Abstract

The present invention discloses an incinerator improved by a sealing means around the pulsating floor or between moving floor parts. The sealing device reduces or prevents ingress and egress of contaminant gases into and out of an incinerator chamber having a moving hearth. The sealing means may be a tank filled with a fluid such as water, sand or small stone-like substances. Alternatively, the sealing means may comprise a refractory material pad connected to the relatively moving parts, a flexible resilient part such as a corrosion resistant spring stainless steel or refractory fibre fixed to one part and pressed against the other part, or a fibre pad refractory material comprising a weave of alumina or silica fibres between the moving parts. The air knife may maintain combustion gases within the main incinerator chamber. The combination of these different sealing means allows to isolate the environment and to avoid the undesirable side effects that may occur with the use of only one type.

Description

The incinerator sealing device

Background technology

John N.Basic, Jr. in its United States Patent (USP) 4438705,4475469,4516510,4706578,5007353,5209169 and 5413715, obtaining very big progress aspect the waste incineration, and " three T " of control burning, i.e. time, temperature and turbulence level how have suitably been disclosed.In first and the 3rd in these patents, Mr. Basic has proposed a kind of incinerating method and equipment, and they are obtaining very big improvement aspect the efficient of burning dissimilar rubbish, and can reclaim heat selectively to make further economic utilization.These two pieces of lists of references have made up three combustion zones, measure temperature in important position, and change burning condition to obtain the desirable efficient and the feature of environmental protection.In addition, these patents can realize these targets under the situation of bulky refuse, and this means before rubbish being incorporated in the main combustion chamber does not need rubbish is handled.This system has versatility, and promptly it can be adapted to visibly different rubbish type, and still can realize the environmental protection burning.

Related principle has so wide applicability in these patents, they in addition can not be fuel with rubbish.These discoveries can be used to realize making the smog burning of the hydrocarbon-containifirst material that is sent by the uncertain source of broad sense.These patents especially comprise the application in these smog when not main incinerator combustion chamber of this system.

But when using main chamber, these patents have also been improved these parts in the incinerator system.These improvements comprise: the first, and stair-stepping furnace bottom, and on the vertical plane of ladder, have air nozzle.As an independent consideration, the amount of oxygen of stoichiometric(al) has been accepted roughly to become with the burning content of this combustion chamber in the incinerator combustion chamber, and the bottom, combustion chamber becomes overall corresponding relation with volume with the thermal capacity of combustion refuse.Independent says, the admission velocity that enters the air of combustion chamber has a upper limit, to avoid that unburned granulated garbage is raise.Perhaps, each size of chamber wall exists specific relation to burn to improve each other.

In second and the 4th above-mentioned patent, Mr. Basic has disclosed how to carry and has dropped on furnace bottom and be likely material on the furnace bottom in main incinerator combustion chamber.These Patent publish the non-sine motion of siege or furnace bottom, in fact this motion makes material pulse forward.The motion of furnace bottom is very similar to shovel snow or other material.Except the garbage disposal that material is especially burnt made progress, pulsating motion can make the progress of garbage disposal quicken and deceleration, therefore effectively pushed away and hit rubbish group, to improve burning velocity and efficient.

Preceding four pieces of patents of above-mentioned Mr. Basic have made up a kind of brand-new system that is used for waste incineration.They have provided the necessary condition of combustion waste, and have disclosed and how to make bulk rubbish move through main chamber to advance this process.Utilize these parameters of setting up, Mr. Basic sets about improving and improving this system then.In this processing procedure, he is in the quantity grade and handle the degree of perfection that has improved his CIU aspect the ability of dissimilar rubbish reliably, this be before just expectation accomplished.Top back three patents authorize exactly this award that keeps punching to him.

One of foremost in these three patents, Mr. Basic has proposed various incinerator improvement projects.In these improvement projects, embodied the theory that the flue that will burn again is divided into two parallel combustion parts again, wherein each again combustion parts can carry out same function to the smog that sends from the source of for example main chamber.Two parallel versatilities that combustion parts provided have again greatly improved the control to three T of burning.

As an independent aspect, this patent is provided with " driver (excitor) " in the flue that burns again.In fact this driver reduces the sectional area of flue central authorities, is the place, position of the mass flow of fuel gas herein, and can force smog gas to pass through around it.Between gas molecule and the wall (be outer wall or excitation wall) distance shorten and the heat followed again radiation greatly improved control to three T.In addition, this driver can be provided with the nozzle of introducing air in flue, is used for carrying out temperature and time control, and guarantees to have enough oxygen to be used for completing combustion.The others of driver comprise the bracing or strutting arrangement that makes air pass driver in the flue that burns again, and guarantee the driver outside to have low thermal conductivity and keep the heat that the residence generates.In addition, this patent has also disclosed a damper has been set in the exit of the flue that burns again, can further control burning time (among three T one).

Ensuing patent US5209169 has disclosed brand-new parts that are placed in the combustion chamber with furnace bottom.Specifically, this combustion chamber can comprise near entrance door and be in fire grate on the siege.This fire grate can support the rubbish with high humility or high B.T.U. content.In the situation of high humility, this material is dried on fire grate.In the situation of high B.T.U. content, some volatile hydrocarbon fuel or dispersed is to prevent overheated and contingent coking phenomenon on furnace bottom.In each case, the hydro carbons rubbish that is fixed passes fire grate and falls, thoroughly to burn on the siege below.Still half that comprises its incendivity hydro carbons when this rubbish for a long time, this rubbish is burning like this.Perhaps, fire grate can have the opening of specific dimensions, to continue with the burning that hockets of remaining above-mentioned rubbish, to realize described target.Fluid for example air or steam passes fire grate, is used to cool off fire grate, and refractory material is used for further protecting fire grate.When fire grate had air to pass, gas can directly enter the combustion chamber, thereby improved efficiency of combustion.Travelling grate can quicken the collision of its content, thereby can carry out desirable burning, and impels dry or partially combusted rubbish is fallen on the following siege.

Last that list piece patent 5413715 relates to and being used for after incinerator places a pond with ashes from wherein taking out the scraper bowl of ash above.This scraper bowl is advanced along a track, and when its arrives basin bottom, thereby this scraper bowl cuts out and can grasp ashes.After track is upwards advanced, scraper bowl is opened, and ashes drop into certain receiving system for example in the truck.

From above as can be seen, pass through Mr.'s Basic creativity and guidance, the technology of waste incineration is greatly improved.As the modern history of the burning that provides above, it all is the new prospect of having opened of further improving that each step advances.Some such progress have below been proposed.

Summary of the invention

It is the combustion chamber of sealing substantially that incinerator has usually, and this combustion chamber has the outlet that is used to introduce the inlet of rubbish and is used to discharge combustion product.The combustion chamber also has bottom part (furnace bottom) and the wall components (furnace wall) that is used to support rubbish, and this wall components is positioned on the bottom part and has formed the periphery of basic closure with bottom part.This wall components provides the described combustion chamber of sealing basically with bottom part.

As top patent 4475469 at John Basic was described, incinerator also can comprise the moving component of certain form that is connected with wall components with bottom part.This moving component makes bottom part move with respect to wall components along basic predetermined path.But some incinerator makes their " bottom part " along accurate path movement.A kind of such system has adopted the design of " rotary furnace " type.Rotary furnace can have simple sealing with outer wall, advances along accurate path with respect to wall because this rotatablely moves.In the patent of quoting in the above, the Basic system on this type incinerator, the especially advantage of its pulsation siege have obtained discussing completely.

But may there be very big deviation in the path that moving component moves bottom part and followed with the predetermined ideal path in the Basic patent 4475469.The reason of these deviations may be that the effect that one or more pulsation bags (pulsing bag) provide is lower or lower than other bag than expection.Perhaps the possibility of the load on the siege one side is bigger than opposite side.These and other factor produces the actual pulsation that has sizable deviation with normal condition possibly.Therefore, and the deviation of ideal path can give and be contained in the space that being used in the incinerator seal between bottom part and the wall components and bring white elephant to prevent any device that air passes between them.

Therefore, an important improvement of this incinerator comprises seal member, and it links to each other with bottom part with wall components, and extends along at least a portion closed perimeter.When moving component makes bottom part with respect to wall device during substantially along its path movement, the sealing parts must prevent basically that closed perimeter that air is mentioned partly is between wall and the bottom part in the above and pass.When bottom part actual path of following and its predefined paths when sizable deviation occurring, the sealing parts especially should be realized this task.

Specifically, the sealing parts at first comprise with bottom part and wall components in a holding member that is connected, be used to keep a kind of on-gaseous material of basic fluidisation.The second, the sealing parts should comprise and bottom part and another immersion device that is connected in the wall components, and when bottom part during along path movement that it is scheduled to substantially, this immersion device to small part is arranged in fluidized mass.

Perhaps, seal member can comprise basic flexibility, the air-locked heat-resistant material net that links to each other with wall components with bottom part.Another kind of possibility is that the sealing parts can be combined with compressible, flexible, the air-locked substantially heat proof material liner that remains between bottom part and the wall components.

Another possibility is, that the sealing parts comprise is flexibility on one that is attached in bottom part and the wall components, air-locked, keep the material of shape (form-retaining) substantially, this material also is pressed against in bottom part and the wall components another, thereby provides friction sealed when bottom part moves.This material can be substantially rigid but some flexible materials stainless steel substrates for example slightly.A kind ofly fully dissimilar friction sealedly can pressing another surperficial air bag on one of them surface simultaneously and constituting by remaining on.This air bag can for example be equipped with the material of the resilient basic solid of air or some other fluids or a kind of flexibility.

As an independent aspect, bottom part can comprise first and second bottom surface portions (furnace bottom section) that intersect along the path of substantially linear.As previously mentioned, bottom part is supporting the rubbish of burning.The wall components that is positioned at this bottom part top has formed the combustion chamber of a base closed with this bottom part.In this case, moving component links to each other with first and second bottom surface portions and wall components, and make first and second bottom surface portions relative to each other and respectively with respect to wall components along the first and second basic predetermined path movement.The improvements here comprise seal member, and it is connected with first and second bottom surface portions, and extend along at least a portion linear path.When moving component made first and second bottom surface portions relative to each other mobile, seal member has prevented substantially that air partly is between first and second bottom surface portions at this linear path to be passed through.

Seal member between two parts of bottom part can be taked the above-mentioned form that is used for the various described interfaces between bottom part and the wall components.In this case, one in seal member and (for example being connected to) first and second bottom surface portions links to each other, and in a comparable manner, with bottom surface and wall between seal member very similarly mode link to each other with another bottom surface portions.That various dissimilar specific sealings can have is friction sealed, net sealing, fibre gasket sealing and fluid sealing.Friction sealed sheet metal sealing and the air sac sealing of comprising again.Any or all types in these sealings can be used as two seal members between the motion bottom surface portions.

More in a broad sense, system can comprise first and second surfaces of intersecting along the substantially linear path.The moving component that links to each other with first and second surfaces makes first surface move with respect to second surface along basic predetermined path.The improvements of this system comprise: link to each other with first and second surfaces and along the seal member of at least a portion of this linear path extension.When moving component with first surface with respect to second surface substantially when predefined paths moves, seal member has prevented substantially that linear path that gas intersects on this first and second surface partly is between first and second surfaces to be passed through.Specifically, when in fact moving component made moving of two surfaces and predefined paths have sizable deviation, the sealing parts must can be accomplished this point.

The above-mentioned seal member that is used for particular type between bottom part and the wall components or that be used for two interfaces between the bottom surface portions can be used between first and second surfaces.As previously mentioned, one in this seal member and first and second surfaces interrelates (for example being connected thereon), and interrelates as between bottom surface and the wall components or seal member and another surface between two parts of bottom part (two furnace bottom sections).

In addition, no matter be that seal member can use two or more dissimilar seal members above-mentioned between bottom part and the wall or between two bottom surface portions or between two surfaces.This combination can comprise the combination of fibre gasket sealing and fluid sealing, friction sealed or net sealing.Other example can adopt the form of fluid sealing and net seal combination under the situation that is with or without the fibre gasket sealing.Other combination can provide good effect for various situations.

Form sealing completely around in the combustion chamber, the siege that moves will need several hermetic units.The direction that will have level that several hermetic units have, other will be along vertical direction.When between two moving hearths Packed the time, sealing also will be along horizontal direction.As a result, according to the concrete needs and the requirement of each hermetic unit, complete sealing may utilize different types of sealing or its combination.

Adopt incinerator to come combustion refuse need make great efforts to improve in this device maybe this device ambient air quality.Incinerator can have the combustion chamber of base closed, and this combustion chamber has and is used to the outlet introducing the inlet of rubbish and be used to discharge combustion product.This combustion chamber also can comprise the bottom part that is used to support combustion refuse, and is positioned at the wall components that the bottom part top is used for forming with bottom part the periphery of basic closure.Wall components and bottom part have formed the combustion chamber of base closed together.Improve around this incinerator or the method for inner air quality comprise make bottom part with respect to wall components along basic predetermined path movement.This method also relate at moving component substantially along this path but and this path prevent that gas from passing through along at least a portion periphery when existing suitable large deviation ground mobile between wall components and bottom part.

Specifically, between wall components and bottom part, pass through in order to prevent gas substantially, need one in described bottom part and described wall components on along keeping the material of fluidised substantially on-gaseous to the small part periphery between bottom part and the wall.Keep one to immerse device along described peripheral part in bottom part and wall components another, when bottom part when its basic predefined paths moves, this installs to small part and is arranged in this material.

As a kind of possibility that uses the immersion system, air-locked heat-resistant material net that can a kind of basic flexibility be connected on the bottom part and along the peripheral part of stipulating along at least a portion periphery and be connected on the wall components.Perhaps can between bottom part and wall components, keep compressible resilient air-locked substantially heat-resisting gasket material along at least a portion periphery.Another kind of optional method be air-locked plate of material that keeps shape with basic flexibility on one that is fixed to the described periphery of small part in bottom part and the wall components, and this material is pressed against in bottom part and the wall components another.

As mentioned above, bottom part can comprise first and second bottom surface portions that intersect along the substantially linear path.In order to improve around such incinerator or inner air quality, at first to comprise described first and second bottom surface portions relative to each other and are respectively moved with respect to wall components along the first and second basic predetermined paths.When moving component makes first and second bottom surface portions relative to each other mobile, prevent substantially that gas from passing through along at least a portion linear path between first and second bottom surface portions.

In general, the method for improving the air quality at least one side in first and second surfaces of joining along a substantially linear path comprises: make first surface with respect to second surface along a basic predetermined path movement.This method also comprises: when first surface with respect to second surface substantially along this predetermined path but when greatly departing from this predefined paths and moving, prevent substantially that gas from passing through along this substantially linear path of at least a portion between first surface and second surface.

Also have, the method for the air quality at least one side on improvement two surfaces in the incinerator that has two bottom surface portions can adopt the above-mentioned special technique that is used to have the incinerator that seals main chamber.But the relation between replacement and wall and the bottom part, this special method will be considered in two parts of bottom part the relation on any or two surfaces here usually.

According to concrete condition that is faced and needs, the practical methods that is used for ad-hoc location can be in conjunction with two kinds, three kinds or multiple technology previously discussed.In addition, different technology can be adopted at the diverse location place of this equipment in for example incinerator combustion chamber of complete closed.Intersect part on relevant wall, bottom surface, bottom surface portions or surface along the non-horizontal line different, especially will do like this with horizontal direction.Certainly, two the pulsation bottom surface portions for example between the siege sealing of junction may need and other surface between diverse ways.

In case of necessity, the combustion position of incinerator can make air enter main chamber by the space between bottom surface and the wall.This will allow to use positive air pressure to stop combustion gas leakage in surrounding environment, especially under the situation of gravity-flow ventilation and induced draught failure.In this case, incinerator will comprise the combustion chamber of base closed, and it has the outlet that is used to introduce the inlet of rubbish and is used to discharge combustion product.In addition, this combustion chamber will comprise the bottom part that is used to support combustion refuse, and be positioned on the bottom part and form the wall components of basic closed perimeter with bottom part, be used for forming with bottom part the combustion chamber of described base closed.This improved incinerator comprises (a) container parts, links to each other with bottom part with wall components on the outside, combustion chamber of base closed, and extends along at least a portion periphery, is used to keep high gas pressure.Specifically, the pressure that can keep surpass pressure and (2) pressure on the outside, combustion chamber of base closed in (1) base closed chamber.Improved incinerator also can comprise the seal member that links to each other with container parts, its can with in the container parts and the gas pressure of the peripheral part of container parts present position be kept above in (1) base closed chamber and (2) pressure on outside, base closed chamber.This higher air pressure will force air to enter main chamber, and prevent that burning gases from entering in the surrounding environment of incinerator along opposite direction.

The sealing of above-mentioned high air pressure can be used with above-mentioned other type seal combination.In fact the existence of other sealing can enter combustion chamber by sealing to air and bring great obstacle, and can reduce the air inlet.In fact, the sealing of other type can make the air inlet reduce to minimum, or even negligible degree.

This combustion chamber also comprises moving component, the pulsing mechanism shown in the US4475469 of Basic for example, and it links to each other with wall with bottom part.As previously mentioned, moving component moves bottom part along basic predetermined path with respect to wall components.In this case, when but moving component made bottom part exist suitable large deviation ground mobile along this predetermined path with this path, seal member had improved in the container parts and at the gas pressure at part periphery place.

When the combustion chamber can be accepted outside air and when not having too much bad effect, can improve incinerator ambient air quality from sealing device.In this case, this method relates to the combustion chamber of base closed, and it has the outlet that is used to introduce the inlet of rubbish and is used to discharge combustion product.This combustion chamber self comprises the bottom part that is used to support combustion refuse, and is positioned on the bottom part and forms the wall components of basic closed perimeter with bottom part, and this wall components is used for forming together with bottom part the combustion chamber of described base closed.Improving incinerator extraneous air method for quality comprises: improve the gas pressure in the container parts, this container parts links to each other with bottom part with wall components on the outside of the combustion chamber of base closed, and extends along at least a portion of described periphery.Specifically, the air pressure in the container parts should be increased to than (1) base closed chamber in and (2) on outside, base closed chamber and pressure height that locate at this part periphery.Certainly gas pressure should remain on and force gas to enter this high level place of combustion chamber rather than other path.

In addition, bottom part is moved along basic predetermined path with respect to wall components and can bring a lot of benefits.However, when moving component existed suitable large deviation ground mobile along this path but with this path bottom part substantially, the gas pressure in the container parts should remain on the high level.

Detailed description of preferred embodiments

Fig. 1 demonstrates a kind of modern incinerator system 75 that has adopted the heat-recovery section that two

pulsation sieges

76 and 77 and two are made of water-cooling wall 78 and boiler 79 substantially at 75 places.In order to begin this process, solid-state bulky refuse enters hopper 82.Plunger type charger 83 advances rubbish substantially by in 84 main chambers of representing therefrom.In main chamber 84, rubbish drops on the first pulsation siege 76, there Bi Yao words it under help, burn from the additional heat of boiler 85.The first pulsation siege 76 moves the rubbish of burning in the mode of the United States Patent (USP) 4475469 of above-mentioned Basic in its surface and towards main chamber 84 away from inlet.At last, the rubbish of this burning is fallen on the second pulsation siege 77, proceeds there to burn.

Air blast

86 and 87 provides air for combustion process.

During incineration firing, it discharges heat naturally.The part of this heat enters water-cooling wall 78 with heating loading fluid wherein.Leave being heated fluid and can flowing in the boiler 79 of film tubular type water-cooling wall 78 then along pipeline 88.The steam of discharging from boiler 79 tops can be with for example being used in incinerator 75 anywhere or being used in the generating or being used for heating.

Rubbish is fallen the ashcan 89 that water is housed from the second pulsation siege 77 after finishing its burning.Scraper bowl 90 by cable 91 pullings that are connected with motor 92 moves along track 93.It is toppled over ashes in the feed hopper 94 then, and it is fallen in the dustbin 95 therefrom.

The gaseous products of burning flows to the path 10 2 from main incinerator combustion chamber 84.There, they with pool together from the gas of the raw refuse in the hopper 82, these gases are advanced along pipeline 104 under the effect of air blast 103.This has eliminated and will be used for driving away the foul smell of raw refuse.

The gas that leaves path 10 2 enters first burning zone 108 more then.There, under the help of auxiliary fuel burners 109 and fan 110 (necessary words), they continue at high temperature to burn to remove the combustible component in air-flow.Along with the burning of combustion of gaseous product is proceeded, these gases enter into second burning zone 11 again, and they burn away there.In the meantime, they receive a certain amount of additional gas from air blast 112 that is controlled.

Second again after the burning zone 111, if in this system in-problem words, these gases can be overflowed by safe release vertical tube 117.But in normal running, baffle plate 118 makes vertical tube 117 keep closing, and these gases advance in the section 4 of system 121.They receive the refrigerating gas that adds from pipeline 122 there.The cooling of the combustion-gas flow that carries out drops to below the various components temperature that for example zinc can gaseous state exists in these gas its temperature like this.Therefore these components are settled out in cooling procedure, therefore enter on the pipe that Shi Buhui condenses in boiler convection device 79 at combustion-gas flow.Advance when passing boiler 79 at these gases that cooled off a little, discharge extra heat and be used for further purposes.As described in the United States Patent (USP) 4438705 of above-mentioned first Basic, first and second again burning

zone

108 and 111 be inserted between water-cooling wall 78 and the boiler 79.This makes the completing combustion that can keep enough heats with the combustible component of realizing this air-flow again in the gas in the burning zone at two.

After leaving boiler 79, this air-flow enters economizer 123.There, this gas stream is with feed-water preheating, and the water that is preheated will be used in the steam generator system that is made of water-cooling wall 78 and boiler 79.Therefore, economizer is further saved from the heat of combustion process and with this heat delivery and is returned and will pass through in the water of this system.This heat of being saved joins in the steam and electric generating means of this CIU 75.

Leave economizer 123, some gases are advanced along pipeline 124 under the effect of air blast 125.This gas has discharged its most of heat certainly in boiler 79 and economizer 123, so its temperature is lower than the temperature when it enters the parts of these back.Therefore, after pipeline 122 is advanced, the zone 121 of its approach section 4 and having reduced as mentioned above from second temperature of the air-flow that feeds of burning zone 111 again.

The remainder that leaves the air-flow of economizer 123 leads to heat exchanger 133 along pipeline 132.Air blast 134 makes extraneous air enter with this air-flow of further cooling by heat exchanger 133.At this moment, these gases have discharged their major parts at boiler 79 and the heat in economizer 123.But the temperature of air-flow still is kept above evaporating temperature, perhaps is higher than the condensing water temperature (dew point) that is included in acid wherein.Heat exchanger 133 is reduced to the temperature that is lower than 400  substantially with this temperature, and in fact the acid in this temperature downstream condense into liquid state.As described below the same, this make it possible to by add alkali neutralize they and in processing subsequently, remove them.

These waste gas receive dry lime stone and active carbon with the acid neutralization that makes condensation respectively and remove pollutant along pipeline 135 then.Enter bag filter and dry acidic Drechsel system 138 by these air-flows that add material then, this washer makes gas and specific separating substances.Solid matter is fallen in the ashcan 141, and it is waited for and being removed there.

Leaving the gas that is cleaned of filter bag 138 advances along pipeline 142.At this moment, have really under the situation of rubbish in the incinerator of operation, any gas can not enter discharge line 142 from pipeline 143, because motor 144 has cut out baffle plate 145 so that burning gases are directed in the filter bag 138.

These gases in pipeline 142 are subjected to the traction of air-introduced machine 148, and they enter atmosphere by the main vertical tube (chimney) 149 of discharging.Continuous blow-down monitoring system 150 can in leaving these gases of vertical tube 149 the various combustion products that may comprise these discharged gases assess.These may comprise particulate, carbon compound, nitrogen oxide, sulfuration effluent etc.The definite task of monitoring system 150 depends on related particular case, comprises the rubbish that these factors for example burn, addressing of incinerator etc.

During start-up function, incinerator 75 uses natural gas that it is heated to its operating temperature in its

burner

85 and 109, and it can begin to receive actual rubbish under this temperature.In this process, in fact waste gas stream do not comprise any component that needs filter bag 138 to remove preheating time.Under these qualifications, baffle plate 145 can be opened and make waste gas can walk around filter bag 138 fully and directly be entered pipeline 142 and standpipe drain 149 through piping 143.But when incinerator 75 had reached its operating temperature, baffle plate 145 was closed, and waste gas stream equally enters filter bag 138 as mentioned above.

Fig. 2 demonstrates the single pulsation siege 158 that is arranged in the main chamber 84.Press against on the retainer 161 to be formed among each figure with airbag 159 that yoke shape spare 160 connects by the pulsating motion of arrow 162 expressions and among Fig. 3 and as the vector Figure 163 described in the United States Patent (USP) 4475469 of Basic.Air blast 165 by pipeline 166 effects provides round the positive air pressure of pulsing siege 158 and entering main chamber 84.According to the geometry in gap between siege 158 and the chamber wall, this positive air pressure can be enough to make effectively the outside of main chamber 84 and the air seal that is mounted in it.

But requirement or even sealing that need be more positive than the sealing that is provided separately by positive air pressure are provided many situations.Therefore this malleation may produce unacceptable gases at high pressure in combustion zone self.Therefore, the physical seal device of pulsation siege may be suitable.In order to ensure effectively, this sealing device must adapt to the motion of siege when it moves by its pulsating motion.This is considering under the situation of the following fact particularly importantly, i.e. the motion of siege is not necessarily definitely foreseeable.Therefore, airbag or other thrust unit not necessarily always produce just in time identical or even symmetrical motion.In addition, the weight of rubbish adds the load distribution difference that may make on it and makes the motion of siege sizable deviation occur from its normal position.

As in Fig. 2 and 3 as can be seen, the combustion zone with its around isolation must need several different positive seal parts.The characteristic of each hermetic unit and structure will depend on that it is with respect to the employed sealing device type in the position of siege and other position on siege.Therefore, siege 158 will have top or charger end horizontal cross sealing device 167, side horizontal seal device 168, lateral vertical sealing device 169 and bottom or ashes end horizontal cross sealing device 170.Positive seal device in these positions will replace or use outside above-mentioned air seal.In addition, the following describes on the single part of the positive seal device that concentrates on usually in the incinerator.Certainly, all parts will interconnect and form inside and the outside gaseous state isolation of closed periphery to realize the combustion chamber usually.Also have, the following describes can be with reference to a kind of ad hoc structure that is used in a position of sealing device.Usually, improving very little or do not having under the improved situation, identical structure can be advantageously used in some other positions of siege.In these situations, being used for therein, the explanation of the sealing device of a position is equally applicable to other installed position usually.

As relate at a kind of positive seal device as shown in Fig. 4-19 with a resilient metal member for example sheet spring steel be fixed on pulsation siege 158 or the outer wall.Making described metalwork be pressed against other surface goes up to produce the friction slip sealing.Such basic sealing device appears at 173 places substantially in Figure 4 and 5.There, corrosion-resistant spring stainless steel substrates 174 has been taked the shape of a kind of being substantially " Z " shape.In Fig. 5, first shank 175 of Z-shaped metal tape 174 is connected securely by on 176 wall constructions shown in schematically.The mid portion 177 of Z extends between wall surface 176 and siege 158.At last, decline 178 forms sweeps 179, this sweep in fact lean against siege 158 from one's body.At siege 158 by its impulse movement and when mobile, the sweep 179 in metal tape 174 slides along siege.This metal tape 174 constitutes and is connected on the wall 176, thereby sweep 179 continues to be pressed against on the siege 158.Lubricant for example molybdenum bisuphide or dry aerosol lubricant helps to reduce by one along another person's side slip and the wearing and tearing on sweep 179 and siege that cause.

Therefore, owing to the compressing that the elasticity of metal tape 174 causes, sweep 179 keeps contacting with siege 158 when it moves through its range of movement.It is also important that, so siege 158 is because above-mentioned factor can have a little side to the side or transverse motion components when it is subjected to its pulsating motion.In other words, siege 158 can be a little when it is pulsed towards or move away from wall surface 176.Yet the elasticity of metal tape 174 adapts to this motion, and the sweep 179 of metal tape keeps contacting so that continuous positive seal to be provided with siege in its whole range of movement.

As mentioned above, the sealing device 173 that is formed by metal tape 174 acts in two ways.At first, its limits, reduces and may prevent to be positioned at the external environment condition that the burning gases above the siege 158 enter incinerator.This is very important certainly, because these gases in main chamber are very harmful for the workman or other people that are positioned near the incinerator.This is located in the situation in the room of sealing particularly like this at incinerator as often occurring.

The second, sealing device 173 has limited extraneous gas and has entered incinerator.Clearly set forth equally as the patent of above-mentioned JohnBasic institute, the thorough environmental protection that realizes rubbish is burnt and need be strict controlled in all factors of main chamber and the burning process in the flue that burns again.Specifically this comprises the air capacity that is incorporated in the main chamber; Gas enters the position of combustion chamber; And the temperature of the gas that imports like this.Sealing device 173 is used for reducing air entered and influenced nocuously the burning of carrying out inside in the siege side periphery quality.This aspect of sealing device 173 and other all aspect described below have special significance according to the following fact, and promptly main chamber (and the flue that burns again) should and be operated under negative pressure with respect to surrounding environment usually really.This negative pressure may cause by inducing of the gravity-flow ventilation of following burning to occur or existence is ventilative.Any of these sources that ventilate or two (that is the negative pressure in main chamber) have guaranteed that burning gases flow along correct direction towards vertical tube.This ventilation will be drawn into air and influence the situation of burning nocuously around siege under the intervention situation of sealing device described here not having.

On the other hand, positive local pressure occurs in the combustion chamber sometimes.This may break down and cause owing to some gravity-flow ventilation and guiding draft fan.In addition, " blast " of the high volatile volatile material in the rubbish or rapid burning can make the pressure in main chamber produce sizable increase.However, positive seal device described here can help prevent the gas in the combustion chamber to escape into the outside, and they may produce sizable injury in this case.

Fig. 6 demonstrates the improvement project of side, the friction sealed device of level, and wherein nuts and bolt is fixed on metal water stop device 185 on the wall 176 184.Metal tape 185 also contacts with sealing with siege 158 and is pressed against on the gas passage.But in Fig. 6, extension spring 187 stretches between metal tape 185 and furnace bottom 188.The power of extension spring 187 firmly contacts with siege 158 when mobile by its pulsating motion the latter pulling down on the metal tape 185 guaranteeing.Certainly, the incinerator structure should be able to have the opening that leads to spring 187 and connection cable 188 thereof usually so that keep in repair or change temporarily.

Fig. 7 demonstrates the improved plan a little that the scheme by Fig. 6 draws.Here, downward-sloping when siege 158 extends by the metal tape 192 of bolt 193 anchorings at it.This makes compression spring 194 it upwards can be promoted firmly to engage with siege 158.Fig. 8 demonstrates another improvement project, wherein bolt 195 make metal tape 196 keep being anchored at siege 158 from one's body.Metal tape 196 slides to provide a kind of friction sealed with respect to wall 176 again.Here, extension spring 197 makes metal tape keep firmly being pressed against on the wall 176 so that a kind of firm sealing to be provided.As for other friction sealed device, should adopt lubricant to avoid spring metal to take now excessive wearing and tearing out of.In addition, the incinerator structure should allow to enter so that can safeguard various sealing devices.In addition, spring should be arranged on the side away from the sealing device of incinerator flame on request.Certainly this is used for preventing that it is subjected to the adverse effect of burning situation.

Fig. 9 demonstrates the spring metal band 201 as the friction sealed device of last charger end level.Bolt 202 makes metal tape 201 keep being pressed against on the incinerator charger end wall 203, and it leans against on the support 204 that is connected on the siege 158 in this case.Extension spring 205 pulls into metal tape 201 with support 204 and firmly engages to guarantee reliable sealing.Support 204 has metal tape 165,192 (Fig. 7) or 196 (Fig. 8) position in line with Fig. 6 on siege 158, so that form continuous seal around the front end corner part of siege.This align structures is schematically illustrated among Fig. 3.

Equally, Figure 10 has the friction sealed device of following ashes end level that has adopted the spring metal band 208 that contacts with the bottom friction of siege 158.Bolt 209 is connected metal tape 208 on the bottom surface 210, and extension spring 211 guarantees that metal tape 208 contacts with siege 158 sealings.

Figure 11 depicts metal tape 215 and be used as the vertical side sealing device near the ashes end 216 of siege 158.Also have, metal tape 215 contacts along straight line 217 and siege are friction sealed.The top 218 of this straight line 217 is connected on Fig. 6,7 and 8 the horizontal side sealing device 185,192 and 196.The bottom of potted line is connected on the bottom ashes end horizontal seal device 208 of Figure 10 always, from and formed the periphery of a closure.

Demonstrate the more contents of vertical friction slip sealing device at Figure 12-14.There, spring leaf metal tape 223 has short leg 224, and it is pressing siege 225 and is sliding.Bolt 228 is connected metal tape 223 by bolt 230 and is fixed on the carriage 229 on the column 231.Carriage 229 makes metal tape 223 keep being pressed against on the side of siege 225.

Figure 15 demonstrates as by the siege 225 that equally moves right shown in the motion arrow 162.The metal tape 236 that contacts with siege is fixed on the column 237 by bolt 239 along carriage 238.Extension spring 240 is connected on the plate 241 that self is installed on the column 242.Another end of spring 240 is connected on the ring 243 that is fixed on the metal tape 236.The tension force of spring 240 makes metal tape 236 keep firmly contacting with siege 225 when siege is advanced by its pulsating motion 162 and therefore becomes sealing relationship with it.Sliding metal band sealing device 236 in Figure 16 is with unique difference of the sealing device in Figure 15, has it is pressed against compression spring 245 on the siege 225.On the contrary, bolt 246 is anchored at spring 245 on the outer wall 247.The view that Figure 15 and 16 drawing demonstrate from the top and see down at vertical sliding sealing device.These accompanying drawings can demonstrate the bottom transverse sealing device of the view of seeing from the side well.Described general structure can be used in two kinds of situations.

Figure 17 demonstrates the improvement structure as the metal tape of being made by the flexure spring steel 251 of friction slip sealing device.Here, metal tape 251 presents a kind of shape of S a little structure, and this makes it contact with siege and contact with fixed structure 253 at bend 254 places down at it in bend 252 places thereon.Bolt 255 is anchored at metal tape 251 on the cantilever 255 that himself is installed on the support 257.At last, bolt 258 is fixed on support 257 and metal tape 251 on the fixed structure 253.

As mentioned above, the warp architecture of metal tape 251 makes it can form two kinds of sliding friction sealings effectively.First sealing appears at uppermost sweep 252 places, and this metal tape 251 is contacting siege 158 there.Second sealing appears at nethermost sweep 254 places, and this metal tape 251 slides along fixed structure 253 there.Therefore, these burning gases rest in the zone 259, and they can not influence away from the perimeter 260 of combustion flame or the remaining structure of metal tape self there.In addition, extrusion metal band 251 helps to guarantee a kind of tight and firm sealing between siege 158 and fixed structure 253.Specifically, metal tape 251 its warp architectures that are made of spring steel must be squeezed or flatten to be assemblied in the space between siege 158 and the underlying structure 253.In the time of in finally being placed in this position, the elasticity of steel attempts to unclamp makes it can be installed in this squeezing action in this position.This trend that steel band 251 will return to its first pre-structure causes it to be pressed against in siege 158 and the substrate 253 to form above-mentioned two sealings.As always the same, adopt molybdenum dioxide will prolong the life-span of sealing device usually at sealing device and these structure position contacting places and reduce needed maintenance with slip or friction sealed situation.

In Figure 18, demonstrate further protection for banded sealing device 174.Nozzle 264 is sprayed onto on the banded sealing device 174 cooling liquid 265 so that its various piece 175,177,178 and 179 coolings.This fluid 265 can be taked for example water or the gas form of air for example of liquid.In either case, fluid 265 protection metal sealing devices 174 can not be subjected to the influence of the stove heat of appearance in the zone 267 between siege 158 and outer wall 176.Huge overheated meeting damages sealing device 174 fully and above-mentioned undesired effect can occur.Ventilation forfeiture in incinerator and flame attempt to move to that heating can take place under the situation of outside, combustion chamber.But, even there is not the sort of situation, heating metal strip is heated to even is lower than under its fracture temperature, then the metal in sealing device still can lose its elasticity with and the ability that contacts with siege 158 of maintenance, and stopped up the passage that gas passes in and out stove zone 267.

Nozzle 264 receives its cooling fluid by control valve 271 from pipeline 270.This valve 271 manual operation fully, and operating personnel open it or close according to the operation of incinerator.When opening, it provides stable chilled fluid flow on incinerator remains on All Time in the user mode.Perhaps, valve 271 can mechanically operation under the control of the temperature sensor 272 of emission types.Determine the temperature of sealing device 174 when sensor 272 and risen to predeterminated level, then it makes valve 271 open with coolant seal device 174.Otherwise this valve 271 keeps closing.Perhaps, As time goes on valve can for example open and close when siege 158 actual pulsation simply off and on.In any situation, nozzle can also be set up air knife in the outside of pulsation siege 158 so that the block piece that is used for making burning gases to remain on the combustion side 267 of incinerator and air is remained on the outside to be provided.

In Figure 19, cooling fluid source is taked the form of box forced air-ventilating system 273, and it receives the air from air blast 274 under pressure.Air leaves forced air-ventilating system 273 with cooled metal bands 278 by the nozzle rows 276 along the surface arrangement of siege 158 under pressure.Air blast 274 can be operated continuously or be subjected to and in the control of the similar temperature sensor 279 of the mechanism shown in Figure 18.Perhaps, air blast can be that air is provided off and on.The air that leaves nozzle rows 276 also is used as and the similar air knife of Figure 18.This helps to prevent that gas from flowing to from the furnace side 267 between mechanically-sealing apparatus described here 278 and pulsation siege 158 or flow out.

Figure 20 demonstrate be installed on the wall projection 285 substantially by the replaceable metal sliding sealing device shown in 284.Nut 286 is screwed on the stud 287 so that sealing device 284 is maintained static.In operation, the bight 288 of sealing device 284 contacts with vertical metal plate 289 on being installed in siege 158 and slides friction sealed to form along its.

As the same shown in this figure, ashes 290 can be accumulated on the furnace side 291 of sealing device 284.When this occurred, operating personnel utilized the inlet that leads to these parts to pull down on elastic metal strip 284 so that ashes 290 are fallen on the furnace bottom simply.In addition, if band 284 is subjected to some by the damage that heat, corrosion etc. cause, then operating personnel can back out nut 286 simply, remove metal tape 284 and with another it are changed.

In Figure 21, between siege 158 and wall 296, be used as horizontal friction slip transverse sealing device by the expandable bags sealing device shown in 295 substantially.The bag 298 that is anchored on the support 297 self can be equipped with air, gas or some other fluids.Bag 298 slides along wall 296 when siege 158 moves.Bag 298 should have enough sponginess or elasticity to adapt to the vertical component and the horizontal component thereof of siege motion.It should also have certain lubrication property at contact point 298 places with wall 296.The surface of bag 295 can be self-lubricating, and perhaps it can need to apply as mentioned above some exterior lubricant.Certainly, the material of bag 295 obviously should be fire-resistant or resistant to elevated temperatures.

Perhaps, bag 295 can be connected on the wall 296 and along support 297 and slide.Can be used for any sealing device in the figure and in the following bag type shown in Figure 22, be included in those and the transverse sealing device between a plurality of moving hearths shown in Fig. 2 and 3 at this incinerator.In Figure 22, or not to expand simply by the sack shown in 301 substantially, but be filled with some solid materials 302.This can comprise sand or solid material for example cobblestone, silica and aluminium oxide, and these materials also have fire resistance.This material 302 must in bag 301, have enough flexibilities with elasticity so that it can be out of shape fully when support 297 moves and still return to its original-shape each other on two structures when mobile subsequently at siege 158.In addition, be used for being applicable to the filling pocket type sealing device 301 of Figure 22 in the explanation of the pocket type sealing device 295 of Figure 21.

Figure 23 and 24 demonstrate along bottom 305 friction of siege 158 substantially by the following ashes end horizontal cross bellows seal device shown in 304.Sealing device 304 comprises by bolt 308 and is installed in rubber tube 307 on the adjustable support carriage 309.And this adjustable bracket 309 is installed in by bolt 311 and is installed in the analog bracket 310 on the following supporting construction 312.Be screwed to adjusting nut 315 on the threaded rod that is installed on the carriage 309 and can regulate the height of air bag 307.

In Figure 25 and 26, demonstrate substantially by the pocket type sealing device shown in 320.There, bolt 321 remains on flexible refractory material net 322 on siege 158 and the outer wall 323.Certainly, this web material 322 must have enough flexibilities so that adapt to pulsating motion by the siege 158 shown in the arrow 162.That is especially found out in vector Figure 163 of Fig. 3 is the same, and this motion at first comprises level component back and forth.Usually, net 322 aspect the horizontal component that adapts to motion without any difficulty.But siege 158 also has component motion upwards.This vertical component applies sizable stress on net 322 when siege carries out its pulsating motion.Obviously, net 322 must have enough elasticity and flexible to adapt to two components of motion.This net 322 can be wrinkling well when siege 158 moves by its pulsating motion.But, should have enough materials to avoid fold, because this can provide the ability of its sealing function to cause negative effect to it.

Figure 27-31 demonstrates the dissimilar water sealing device of describing in detail in drawing subsequently.Therefore, specifically Figure 27 demonstrates substantially by the horizontal water sealing device in the side shown in 327.Here, the groove 328 of water 329 is connected on the outer wall 330.Blade 331 or metal tape are connected on the lateral member 332 or form as one with it, and this sheet metal is connected on the siege 158 with the relation of fluid sealing again.Blade 331 in water 329 forms fluid barrier between furnace side 333 and external environment condition 334.As seeing in this drawing, the groove 328 of water 329 is easy to adapt to the horizontal movement of siege 158 these papers of turnover.But the degree of depth of groove 328 also keeps sealing during the moving both vertically of siege 158, and siege can rise 4 inches during its pulsating motion usually.

Figure 28 demonstrates substantially by the last charger end transverse horizontal water sealing device shown in 340.Here, the support 341 that is installed on the siege 158 is fixed on blade 342 in the water 343.Groove 344 is holding water 343 and is being installed on the fixed surface 345.Groove 344 should not move together with siege 158, because water 343 is rocked out when siege 158 moves by its pulsating motion.In addition, blade 342 is towards as being tilted by the same siege direction of motion shown in the arrow 162.This helps to prevent that blade 342 from taking water 343 when being moved to the left out of at siege 158 seeing among Figure 28 from groove 344.Also have, sealing device 340 forms retention device between the furnace side 347 of main chamber and outside 348.

Following ashes end transverse horizontal water sealing device in Figure 29 substantially by shown in 350.Blade 351 is installed on the bottom of siege 158 and is located in the water 352 that is kept by groove 353.As for the drawing of front, groove 353 is connected on the static surface 354, thereby water 352 spills by its pulsating motion Shi Buhui that jolts at siege 158.In addition, blade 351 tilts to enter the direction of motion seen from arrow 162 to avoid taking water 352 in the figure left between moving period out of at siege.

Figure 30 and 31 demonstrates very special substantially by the vertical side water sealing device shown in 360.The difficulty of vertical water sealing device is caused by its orientation.All horizontal seal devices have adopted the blade that is immersed in the open level trough.Obviously, that is not suitable for the vertical seal device; The water that the vertical open groove can only allow all to need therefrom flows out.Therefore, Figure 30 and 31 demonstrates and will realize the layout of vertical water sealing.There, water receptacle 361 by three vertical side 362,363 and 364 and bottom 365 form.Two

outsides

362 and 364 have

lip

366 and 368 respectively, and this bottom 365 has

lip equally.Side

362 and 364, bottom 365 and

lip

366 and 368 also have on bottom 365 lip all have the component of for example suitable rubber of some flexibility, elasticity and heat proof material.

The external compression spring 373 that is anchored on the outer wall 374 is pressed against water receptacle 361 on the pulsation siege 158.This compressing causes these sides, bottom and lip as being pressed against the wiping blade on the siege 158 and having reduced water passing through and lose between water receptacle 361 and siege wall with

side

362 and 364, bottom 365 and their corresponding lips.In addition, along its pulsation direction 162 when moving, side, bottom and lip be as the wiping blade of advancing on the siege surface at siege 158, from and reduced the loss of water.

But in all possibilities, some water will especially overflow between the moving period of siege 158 from container 361.In order to compensate this leakage, feed-line 375 is connected container 361 on the storage cistern 376.Replaced the water that may leak out arbitrarily from the water of storage cistern 376 from container 361.Usually, float or other device can confirm that the water in storage cistern 376 rests on the horizontal plane that must substitute any water of forfeiture from container 361.

At as described in the sealing device of other type, the sealing fully around the siege 158 needs closed for example at those the periphery of sealing device part shown in Figure 27-31 usually as the front.Therefore, in order to have closed water sealing device periphery, the incinerator main chamber with single pulsation siege 158 will have side horizontal seal device 327 (Figure 27's) on each side; Charger end horizontal cross sealing device 340 (Figure 28's) on the charger place of siege 158 has; Following ashes end horizontal cross sealing device 350 (Figure 29's); And between upper side horizontal seal device 327 on each side and following transverse sealing device 350, has vertical side sealing device 360 (Figure 30 and 31) on each side of siege.In addition, leak for fear of occurring, should form if their water all is in identical horizontal plane place as below with reference to the same continuous pond shown in Figure 50-53 in the connecting portion office of two sealing devices.Can utilize these sealing devices of the advantage in continuous pond to comprise horizontal side sealing device 327 and last charger end horizontal seal device 340.In theory, it can also be combined with lateral vertical sealing device 360, but the latter's leakage problem can influence other sealing device.

Above-mentioned explanation appears to all parts that will advise for round the periphery of siege and adopts water sealing devices (perhaps any one sealing device).Therefore, Figure 27-31 provides a kind of water sealing device that is used for all parts of whole siege sealing devices.But, that not necessarily this situation.Specifically, as mentioned above, has bigger leakage possibility inherently at the vertical water sealing device 360 shown in Figure 30 and 31.Therefore, the practical structures of incinerator can adopt water (or some other fluids) sealing device to all parts except vertical seal.This last sealing can be taked the form of above-mentioned friction sealed device.No matter its form of this sealing device must closely contact with following horizontal water sealing device with the side level, it links together them there.

Usually, container 328,344 and 353 and tank described below will have stainless component to avoid corrosion from the incinerator burning gases.For blade 331,342 and 351 and below the explanation in those also be same.Specifically, burning gases can comprise chlorine, and many plastic fractions produce hydrochloric acid when for example chlorine is in being dissolved in water.Stainless steel helps avoid the corrosion effect of acid.For further protection is provided, water can contain the alkali of interpolation with the described acid that neutralizes.If burning gases produce alkali when dissolving, then the water in groove can comprise the acid of neutralization.

Water 329,343 and 352 in groove 328,344 and 353 provides further significant advantage respectively.Specifically, it has cooled off blade 331,342 and 351.These blades directly or indirectly are exposed to the hot gas of burning in incinerator operating period.This hot environment can be damaged these blades.Water cooling these blades and help avoid this damage effect.Identical explanation is applicable to on the blade in the water sealing device below.The specific sealing device for example further feature of heat resistance fiber liner can reduce this problem.But water has avoided damaging or damaging the high temperature of stainless steel blade really.

Figure 32 and Figure 33 (more detailed) demonstrate substantially by the following ashes end horizontal cross sealing device shown in 379.Briefly relatively demonstrating of these accompanying drawings, they have the similarity very big with the bellows seal device of Figure 23 and 24.But in current situation, adjustable bracket 309 is supporting the groove 380 of water 381, and this groove is assembled in the otch 382 of support member 312.The bottom of groove 380 comprises the gutter 385 that has stopper, thereby water 381 can be discharged.

Compressor arm 386 with the ventilative net 387 of flexibility with airtight mode be connected siege 158 following 305 on.Net 387 can be taked the Wilmington by DuPont Company of, 1/8 inch thick composition kevlar  that Delaware makes and Nomex  aromatic poly-amide fabric or equivalent.Different sacks for example staple fibre, glass fibre Goretex etc. especially those sacks with eyelet of several microns can satisfy the demand.Other thickness that provides thickness above being greater than or less than is suitable equally.The bottom of net 387 is arranged in the water 381 to provide gas-tight seal between furnace side 388 and outside 389.The bottommost of net 387 is wrapped on the bar counterweight 390 so that it is remained in the water 381.As before, which type of form the latter takes no matter bottom level transverse sealing device 379 should be aimed at lateral vertical sealing device 391.

In Figure 34, be very similar to net water sealing device 379 in the prior figures by the sealing device shown in 394 substantially.But in this situation, the sealing device has adopted the rigid blade of being made by corrosion resistant plate 395 that is immersed in the water 381 to form the sealing device.Bar 386 makes blade 395 keep motionless (under the help of the parts that are not equivalent to weight linear meter 390).

Figure 35 and 36 schematically demonstrates respectively and similarly goes up ashes end horizontal cross

water sealing device

401 and 402 with the following ashes end sealing device of Figure 33 and 34.These two holddown grooves 403 that all adopted to be installed on the structure 404 hold water 405.Groove lid 408 forms a side of retention device between furnace gases zone 409 and outside 410.It also allows to enter groove 403 to clean.Lid 408 is installed on the fixed structure 412.

In Figure 35, gripper shoe 413 is connected on the anchorage clip 414 that is fixed on the siege 158.And compressor arm 417 is connected flexible material net 418 on the gripper shoe 413 similarly with Figure 33.Bar counterweight 419 remains in the water 405 net 418.In Figure 36, corrosion resistant plate 422 has replaced the net 418 in the prior figures, and is fixed on the gripper shoe 413 by bar 417.As at charger end or ashes end place as other steel plate of transverse sealing device, this plate 422 should be made into respect to horizontal direction and become relative low-angle.This will help avoid and make this plate 422 when siege 158 moves by its pulsating motion 162 water 405 be released groove 403.Usually the net 418 that is accompanied by the net water sealing device as if during the siege pulsation specific rigidity blade water sealing device move still less water.

Figure 37 and 38 demonstrates respectively substantially by the charger end horizontal cross water sealing device shown in 425 and 426.In these two, supporting construction 427 remains on groove 428 in the fixed position, thereby water 429 remains on wherein.Pulsation siege 158 has the gripper shoe 430 that connects thereon by clip 431.Bolt 434 is fixed on restraint zone 435 and the stainless steel blade in Figure 37 436 on the gripper shoe 430.Blade 436 in water 429 forms sealing between furnace side 437 and outside 438.Sealing device 425 should with aim at and be attached thereto by the side horizontal seal device shown in the horizontal line 439.This relation is applicable to below at Figure 50-53 explanation of being done.Sealing device cover plate 440 rotates allowing around hinge 441 and enters in the water 429.

In Figure 38, bolt 434 and restraint zone 435 are clipped in firmly by weight linear meter 443 and are pressed on flexible fire-resistant being with on 442 in the water 429.In water 429, be with 442 between stove environment 437 and outside 438, to form sealing device.In addition, the top explanation about Figure 37 here is suitable for.

Figure 39 and 40 demonstrates bottom ashes end horizontal cross sealing 447 and 448 respectively substantially, and they are basic the same with the water sealing device 394 of Figure 34.But sealing

device

447 and 448 is used in and is arranged in 451 furnace gas and can takes place under the situation of bad reactions with the water 381 of sealing device 394.When for example rubbish contained a large amount of disposable infant diapers, this thing happens in meeting.In these diapers as the gasification of the polymer gel of absorbent, can form colloidal gel with water in the time of in being dissolved in water 381 and with its curing.This has tangible the conflict with notion and the operation above discussed with " fluid sealing ".

Therefore, replace water as sealing medium, the groove 380 of Figure 39 adopts sand 452 that sealing is provided.Similarly, Figure 40 has shown that bubble medium 453 is as fluid.In the latter case, bubble can be made of the handstone or the particle of aluminium dioxide or silica.453 of the fluid media (medium) 452 of Figure 39 and Figure 40 is positioned on the detailed catalogue screen cloth 456 that is soldered to groove 380.Tracheae 457 be positioned on the top of groove 380 and screen cloth 456 below.Tracheae 457 provides air in the space 458 between the bottom of screen cloth 456 and groove 380.Air is upward through screen cloth 456 then, thereby helps fluidizing agent 452 and 453.Tracheae 457 can provide air continuously, off and on, does not perhaps provide according to the character of the rubbish that burns at all.In fact, Figure 62 and Figure 64 represent to use this medium, but do not have air or any other gas to pass these media.But when pipe 457 provided air off and on, they can provide according to the sequential relevant with the pulsation of siege 158.Therefore, they may be operated in the one-period that beginning also finishes after pulsation just before the pulsation just.Be practical especially like this, because in fact the pulsation of siege can cause the air pressure inside in the main combustion chamber to raise slightly.In this concrete cycle, reduce and maybe may reduce required ventilation and show in this time and will use tracheae 457.

When tracheae 457 provides air really in groove 380, they just provide fluid to flow on the outside of siege 158.This can be used as air knife and helps prevent burning gases from 451 effusions of stove zone, and is similar with the fluid stream of Figure 18 and 19.

Figure 41 and 42 has shown equally respectively and has been in 461 and 462 sealing device substantially that they are very similar to the sealing device 402 of Figure 36.Herein, groove 403 have welding thereon and with the pipe 464 equitant small meshes 463.Pipe 464 is introduced air or gas in the space 466 under screen cloth 463.Sand 467 is arranged on the screen cloth 463 of Figure 41, and bubble material 468 has been filled the space in Figure 42.In either case, steel disc 422 remains in sand 467 or the bubble material 468 so that sealing to be provided.The same with Figure 39 and 40, tracheae can be introduced air continuously, off and in this space, or does not according to circumstances introduce gas at all, with further fluidizing agent 467 or 468.The same with Figure 36, sealing

device

461 and 462 generally drops on the line 410 of side horizontal seal device and is attached thereto.

Incinerator as shown in Figure 1 can have two

sieges

76 and 77 even more sieges.The sealing device that the complete closed of main chamber inside also need link together them between these two sieges.This sealing device between two sieges must worked under the exacting terms more: at first, two sieges are pulsed; The pulsation repetitive rate of the second, two siege is normally different, and the common ripple frequency of following siege is lower than upward siege; The three, two siege has the improper path different with they normal routes separately.In fact water sealing device between two sieges combines the upper load end horizontal seal device of bottom ashes end horizontal seal device and following siege on the siege.In these sealing devices each is with in the tank that blade stretches into some mobile object is connected.The water sealing device of this centre also is applicable to following explanation about Figure 43-48 and Figure 57.Perhaps the sealing between two sieges can be adopted the seal form outside the above water-stop.Same mark can be used for these the different sealing devices between the siege.

Figure 43 and more detailed Figure 44 have shown the siege 158a and the 158b of two tandem operations.Along the direction pulsation of 162a and 162b, ripple frequency and the intensity of

siege

158a and 158b generally are differing from each other certainly usually for they.This situation can be with reference to the

twin furnace bed

76 and 77 of Fig. 1.Perhaps, when main chamber has three or more siege, in the time of shown in Figure 57, also can this thing happens.In fact, can be used between any two pulsation sieges substantially by the by-level transverse sealing device shown in 475.

Shown in Figure 43 and 44, sealing device 475 utterly will be combined by the lower horizontal ashes end type sealing devices of 476 expressions and the sealing device of upper load end horizontal type by 477 expressions.Figure 34 has shown last type sealing device, and Figure 37 has shown back one type sealing device.In Figure 43, last siege 158a has the continuous blade in the water 479 that remains in the groove 480 that is fixed in stationary face 481.Similarly, following siege 158b has the blade 485 that links to each other that also is in the water 479.Have the blade 478 of two submergences and 485 water 479 sealing device between ring border 486 and outside 487 is provided.

For last siege 158a, the vertical side seal setting position shown in sealing device that blade 478 provides and the dotted line 488 aligns.Equally, for following siege 158b, the sealing device 477 of blade 485 aligns with the upper side horizontal seal device of the siege shown in the dotted line 489.Two

blades

478 and 485 are positioned on the same horizontal plane that potted line 489 set up.The relative position of these sealings provides the periphery of a closure, and the continuous sealing that strides across two

pulsation siege

158a and 158b that therefore forms.

Figure 44 at length demonstrates the tank 480 that is positioned on the stationary structure 481, and this tank does not contact with last siege 158a or following siege 158b.The mobile meeting that prevents siege like this causes water 479 to overflow tank 480.

Figure 45 has described the by-level transverse sealing device that is positioned at 490 places between two

siege

158a and 158b, and the sealing device 475 in sealing device and the prior figures is practically identical.Groove 491 is positioned on the static surface 492 and maintains water 493.Be arranged in water 493 from the

blade

494 and 495 of

siege

158a and 158b up and down respectively, so that water-stop to be provided.But Figure 45 also comprises by compressible, additional seal device 496 that elastomer liner 497 forms between siege 158a and 158b.Alloy pin 498 is anchored at liner 497 on the steel plate 499 of the refractory material 500 that is covered with down siege 158b.Along with in the siege one or two pulsed, fibre gasket 497 presses against steel plate 502 on the bottom of refractory material 503 of siege 158a, and it is rubbed.But when

siege

158a and 158b mobile made that they become minimum the separation each other, the length of pin 498 must not can make them contact with the steel plate 502 of last siege 158a.

High-temperature lubricant (normally molybdenum bisuphide) between liner 497 and last siege 158a helps the former and moves with respect to the latter.This lubricant is sprayed on liner 497 and the steel plate 502 usually.Avoid the heat of the combustion flame in the main chamber 504 by protective lining 497 and encroach on, liner 497 has symbiosis with lubricant.

Liner 497 should have the component of the gas of resisting high temperature and producing in incinerator environment 504.Fibre gasket 497 should demonstrate enough compressibilities and elasticity, to fill this space 505 when making space 505 between siege 158a and the 158b increase and reduce at

siege

158a and 158b mobile 162a and 162b separately.The liner that is made of the braided fiber of the mixture of aluminium oxide, silica or these two kinds of combinations can be used for this purpose.

Liner 497 is used for substantially and greatly making heat corrosive of water 493 and incinerator and has destructive gaseous environment 504 and keeps apart, and this environment especially can damage sealing 485.In other words, it can be used as the fire prevention thing.Because liner 497 can not provide complete sealing usually, water 493 can stop may be by any gas of liner 497 effusions.As mentioned above, and according to the rubbish that burns, water 493 does not need liner 500 just can provide enough sealings.Equally, this situation also allows liner 497 as a complete sealing device, thereby has omitted the needs that water sealing device 490 is existed fully.

When liner 497 provided sealing between siege 158a and the 158b, the vertical sealing that is used for the former should fall (fall) along line 506.This also provides the closed perimeter that is used for complete seal.In addition, advise, be similar to the fibre gasket self of liner 497 or combine, can form upper load end horizontal cross sealing device or bottom ashes end horizontal seal device with other type sealing device of for example water sealing device as this figure.

Figure 46 demonstrates water sealing device 490 in fact the same with the figure of front and liner sealing device 507.But liner 508 friction herein is arranged in the steel plate 509 of groove 510 of the refractory material 503 of siege 158a lower surface 511.Along with two

siege

158a and 158b relative to each other move, groove 510 helps to be anchored in down by pin 512 controls liner 509 mobile of siege 158b.Underlined can being used for herein that is used for Figure 45 in addition.

Figure 47 represents to lay respectively at usually the horizontal water sealing device of by-level at 512 places between upper and lower siege 158a and the 158b.This figure is very similar to the water sealing device 475 of Figure 43 and 44.But go up the flexible net 513 and 514 that siege 158a and following siege 158b are connected to the water 515 that is arranged in groove 516 respectively herein.Weight linear meter 517 with 518 with net 513 with 514 separately the bottom link to each other, be used for holding them in water 515.The side of line 517 expressions of last siege 158a vertically sealing aligns with the net 513 that links to each other with this siege.Similarly, the side horizontal seal drops on down on the line 518 of siege.These directions provide the closed perimeter that strides across two siege junctions, thereby provide sealing between stove fire side 519 and outer side 520.

Have same forming by the sealing device 475 of the sealing device shown in 521 and Figure 44 substantially among Figure 48.Therefore two figure use same Reference numeral.But the sealing device of this figure also has two additional parts at present.At first, it comprises the fibre gasket 522 that is anchored at down the resilient flexible on the siege 158b by steel pin 523.This liner 522 is used for liner 495 and the 504 same sealing purposes with Figure 45 and 46, and operation in the same way.

In addition, sealing device 521 comprises by support belt 525 and 526 and presses on

blade

478 and 485 bag 523 that keeps motionless respectively.For sealing effectively is provided, bag 523 must seal fully wraps up in blade 478 and 485.It should have enough elasticity with adapt to

siege

158a and 158b they pulsation 162a and 162b in move.At last, the component of bag 523 should allow it to withstand the environment of incineration area 486, perhaps, should can pass fibre gasket 522 at least as much as possible when it is included in this structure.Figure 25 and 26 bag 322 described materials are enough to satisfy the needs be used for bag 523 herein.

Sealing device 521 among Figure 48 comprises bag 523,

water

479 and 522 3 kinds of parts of fibre gasket.According to the environment in the incinerator main chamber 486, have only above-mentioned two kinds or even during a kind of part, sealing device 521 also can suitably be carried out its function.Specifically,

blade

478 and 485 is used for bag 523 is remained on water 479, and provides water-stop when bag 523 is out of order.Therefore, if situation discussed above represents to omit water 479 (and may omit groove 480), sealing device 521 can not need

blade

478 and 485 so.

Figure 49 represents the main incinerator combustion chambers with the combustion chamber 84 of Fig. 1 very similar (still from opposite side) 527 expressions.Combustion chamber 527 comprises

siege

158a and 158b up and down.Cable 531a hangs from the crossbeam 532a of stationary structure 533, and under the beam 534a of pulsation siege 158a around.Therefore cable 531a is used for siege 158a is suspended in midair from superstructure 533, and makes its swing according to the sus-pension slightly of the mobile 162a of pulsation described in the US4475469 of Basic.Similarly mark is used for remaining by the cable 531b around the beam 532b that is looped around static superstructure 533 the following siege 158b of suspension.

Last siege 158a accepts from load end transverse sealing device and groove 537, side horizontal seal device and groove 538a, vertical side seal device 529a and the horizontal cross sealing device of centre and the isolating seal of groove 540.Equally, the seal perimeter round following siege 158b also comprises intermediate lateral sealing device and groove 540, side horizontal seal device and groove 538b, the vertical sealing device 539b in side and bottom ashes end horizontal cross sealing device 541.All above-mentioned sealing devices are connected to each other, and form the periphery of a closure, therefore seal fully

siege

158a and 158b around, so that the inside and the external isolation of incinerator are opened.Except

vertical sealing device

539a and 539b, can use the water in the groove in these all sealing devices.As shown in the figure, vertically sealing

device

539a and 539b have adopted the friction of aforesaid some form or bag to seal.The water sealing device of siege 158b interconnects shown in Figure 50-53 under being used for.The icotype that has short slightly side can be used for siege 158a.

The interconnective tank systems of following siege 158b that is used for Figure 49 at Figure 50 substantially by shown in 545.It comprises the level trough 546 on two sides that are connected upper level transverse groove 547.Tank systems 545 keeps static in the superstructure 533 of Figure 49.Because similarly structure is used for the tank systems 545 of siege 158a and following siege 158b, thus below be referred to as overall siege 158 usually.

Water in side channel 546 and translot 547 can be freely in the bight 548 places (having shown among Figure 51) flowing to each other.As shown in the figure, the transverse sealing groove 547 of level is shown in dotted line, because it is arranged in the back that (figure) is used for the groove 546 of side horizontal seal device.Two grooves interconnect, and can flow in another from the water in the groove, thereby continuous seal is provided.Conjunction 552 links together two grooves, and the cover plate 553 that links to each other by hinge 554 allows near this transverse groove 547.

Figure 52 demonstrates the bight 555 of pulsation siege 158.Siege 158 has the side blade 556 that links to each other with its sidewall 557.The end of siege 158 has the horizontal flexibility net 418 (also as shown in figure 35) of end.Shown in Figure 52, flexible net 418 presses on the side blade 556 tightly, passes through therein to prevent gas.Similarly the side blade connects on the other end of the net 418 that does not have demonstration in the drawings.There is not the continuous interconnection structure of the side blade that shows to be arranged in the groove structure 545 of filling water of Figure 50 among side blade 556, flexible net 418 and Figure 52, to form the continuous water-stop that links to each other round siege 158 3 sides.In order to finish sealing, two vertical sealing meetings link to each other with the bottom of the end 558 of the lateral groove 546 of Figure 50.Horizontal (water) sealing device of lower horizontal links to each other with the bottom of this vertical sealing device then, so that the closed perimeter round siege to be provided.

The siege 158 of Figure 53 is very similar to the siege of Figure 52, and what still replace flexible net 418 is that it has stainless steel blade 422 (being similar to shown in Figure 36).Set up an airtight intersection along side blade 556 and the crossing line 559 of steel blade, thereby can provide sealing at the place, bight of siege 158.

Figure 54 demonstrates the part of the lateral groove of originally seeing 546 in Figure 50, but this part is connected on the part of outer, stationary superstructure 56 1 of main incinerator combustion chamber.These two figure expression lateral grooves comprise the plate-like slot part 562-567 that is made by for example stainless resistant material usually.Plate-like groove 562-567 allows to enter from the outside this dish 563-567 and so enters the water of lateral groove 546 so that safeguard.In addition, dish 565 has connector 571 in its bottom, discharges to allow the water in this tank systems.And coil 563 and comprise buoyage 574, it is used for still the water in the tank systems being remained on desirable water level under the situation that evaporation is arranged and overflow.

Shown in Figure 54 and 55, dish 562-567 has the baffle plate 575 that extends from left to right.Baffle plate 575 immerses in (in the sealing 538 of Figure 55) water 576, to prevent entering perimeter 578 from the gas in combustion flame district 577 through this dish.But baffle plate 575 can not extend to dish 564 bottom always, can stay path 581 in its bottom, make water can be below and between the part 582 that side blade 556 is in water, the flowing back and forth of lateral groove 546.

Because following various reasons, the dish 562-567 among Figure 50,54 and 55 place of joining end to end of groove 546 from the side forms single continuum.At first, this dish can not extend through the support column 583 of stationary structure 561.The second, the beam 532b that lifts siege has prevented the displacement that dish occurs in the part 584 that meeting is subjected to displacement.Do not coil in these zones, groove 546 has the U-shaped of being given by the trench bottom 587 that occurs after post 583 and part 584.However, lateral groove 546 provides continuous groove 582, and the side blade 556 of siege 158 (seeing Figure 52 and 53) is positioned at this groove.Obviously, between groove 546, dish 562-567, post 583, groove 582 and baffle plate 575, be necessary for gas-tight seal, to prevent to leak to the burning situation 577 of gas from its inside outside 578.

In Figure 55 and 56, demonstrate other details of horizontal side sealing device.Herein, siege 158 has refractory coating 590.Pipe 591 provides the air of underfire by the refractory material 590 of wall 592 for the incineration firing on the siege 158.Vertical refractory walls 592 has the part 593 of appearing towards incinerator inside.This appear 593 tend to prevent be trapped in zone 596 between siege and the static furnace roof (roof) 597 from the central authorities of siege rubbish that push open and that push the side in.Furnace roof 597 has fire-resistant soil layer 598.The sidewall 599 of furnace roof has the pipe 600 that passes it, with the combustion air that provides top to introduce to combustion refuse.Furnace roof 597 has one and is positioned at appearing of siege 158 and hangs part 603 on 593.Hanging part 603 helps avoid material, dust etc. and enters space 596.

Figure 57 demonstrates three

pulse siege

158a, 158b and the 158c that tandem is provided with simply.Each has separately the horizontal water sealing device 538a in side, 538b and 538c respectively.

Figure 58 demonstrates and the horizontal water sealing device 538 in the similar side of Figure 55.In addition, it has the fibre gasket 606 in siege 158 and furnace roof hang space 596 between the part 603.Alloy pin 607 is anchored in liner 606 on the refractory material 590 and steel plate 608 of sidewall 592 of siege 158.Fibre gasket 606 corresponding mobile, siege 158 frictions cover the steel plate 609 that furnace roof hangs the refractory material 610 of part 603.Therefore, liner 606 should have and intersects with steel plate 609 and to its lubricated surface that rubs 611.

The siege of Figure 58 shifts out with respect to the paper shift-in.Obviously, fibre gasket 606 must adapt to this and moves horizontally.In addition, in it move horizontally, siege 158 also has vertical component motion.For suitable under these conditions operation, liner 606 must have enough flexibilities can bear this compression at sidewall 592 with when hanging between the part 603 extruding.Can expand when enough elasticity hangs part 603 to move away at siege 158 and fill up this space but it also must have.Mark about

fibre gasket

495 and 504 among Figure 45 and 46 also can be used for herein.

Figure 59 demonstrates the fibre gasket 613 that is anchored in siege 158 sidewalls 592 equally by steel pin 614 equally.But on the lubricated steel sheet 615 in the groove 616 of liner 613 under the static refractory material that hangs part 603 610, and move in this case, with respect to it.Shown in Figure 58, the figure illustrates the water sealing device 538 except that liner 613.Under certain situation, self is just enough in each case for liner.

Figure 60 is in fact the same with the figure of front, but has increased the capsule bag 618 that is positioned at groove 582 and complete closed blade 556.Be with 619 capsule bag 618 is connected with siege 158, with 620 columns 583 that equally capsule bag 618 are fixed in stationary structure.The same with Figure 48, capsule bag sealing device 618 has formed the triple seal that comprises water 576, liner 613 and capsule bag 618 for siege 158.For concrete situation, may not need all these.Specifically, water 676 can not avoid using blade 556.The explanation of the horizontal cross sealing of Figure 48 can be used for the horizontal seal device of side.

Figure 61-65 is illustrated in the groove 582 that the column 583 that links to each other with stationary structure links to each other and uses different media 623.In the mode of Tao Luning, blade 556 is inserted into the side seal that level is provided in the medium 623 in the above.Do not consider the character that it is definite, medium 623 should allow siege to pass through its pulsation and arcuate motion, and can not damage groove 582, blade 556 or medium 623.In addition, any medium can be used in combination to form multi-sealed with aforesaid for example fibre gasket, capsule bag or this other sealing of two kinds.

Under any circumstance, Figure 61 has represented to adopt the medium 623 of water 576 forms in the prior figures.At Figure 62, sand 626 is arranged in lateral groove 582, as sealing medium.In Figure 63, detailed catalogue screen cloth 627 be welded on groove 582 bottoms near.Sand 628 be positioned at screen cloth 627 above.Conduit 631 enters the groove under the screen cloth 627, air or other gas can be introduced by its opening 632, to help when needed further fluidisation sand 628.With above-mentioned the same with regard to Figure 39-42 discussion of being carried out, air can be introduced or introducing not at all continuously, off and on.This air also provides positive pressure, to help prevent the stove district effusion of burning gases from incinerator, as the air blast 165 of Fig. 2 is done.

The

bubble material

635 and 636 of for example handstone, aluminium oxide or silica shown in Figure 64 and 65 has replaced the

sand
