Description
Technical field
The present invention relates to a kind of equipment, this equipment comprises:
-boiler, for holding and heating liquid such as water; And
-cold liquid system, itself and boiler have fluid connection, and it is for holding the liquid lower than the hot liquid temperature from boiler.
Background technology
Equipment as mentioned in opening paragraph is well-known in practice.Such as, this equipment can be water correction plant.In many cases, such equipment is the equipment based on gravity, and wherein water only uses pump etc. to flow through equipment and the filter as an equipment part under the influence of gravity and not.Therefore, in such devices, boiler is arranged in the horizontal plane lower than cold liquid system, and this cold liquid system comprises storage box in many practical situations.In addition, in such devices, the pipe-line system by storage box and boiler interconnection is provided for.The running of the various elements of this equipment adapts to following true: only have very low-pressure in the device, because only can apply the height of the water column owing to extending between storage box and boiler and the pressure that produces.
The conventional water correction plant based on gravity relates to following problem: when activating boiler to heat a certain amount of water, also heats the water be present in storage box.Suppose that storage box holds the water being in room temperature, but be connected owing to existing between storage box with boiler, so the water temperature in storage box increases when activating boiler.In this regard, note, regardless of for holding and/or transmitting the pipeline of water and the shape of other elements or size, between a large amount of water that temperature is different, always having hot-fluid.Owing to being only that main this is true in a device with low pressure, disconnect so complicated valve (such as spring-opposed valve or comprise the valve of movable part) can not be applied with the water to make in the hot water in boiler and storage box much cold.
Hot water in boiler has than storage box and by the low density of water in the pipe-line system of storage box and boiler interconnection.Due to density contrast, so hot water tends to rise to higher level face in a device and shift to storage box, and cold water tends to sink in a device.Thus, the water in storage box becomes warmer in time, and boiler needs to use energy to heat the cold water sunk.
Summary of the invention
The object of the present invention is to provide the solution for the problems referred to above, the water temperature that this problem is in storage box undesirably increases because relatively hot water flows to storage box from boiler.Object of the present invention is also to provide the solution for the problems referred to above, and the energy that this problem be the water in order to heat in boiler and need undesirably increases because relatively cold water flows to boiler from storage box.
According to the present invention, provide a kind of equipment comprising boiler and cold liquid system as described in the text, wherein this equipment is also equipped with and is back to cold liquid system from boiler for preventing and realizes adiabatic device for the position in boiler upstream.
Note being back to cold liquid system from boiler for preventing and comprising described two kinds of functions be incorporated in single structure wherein for realizing adiabatic device in the position of boiler upstream.Such as, in order to anti-backflow, can comprise for allowing liquid from cold liquid system to the flowing of the direction of boiler and for the check valve of obstructed flow in the other direction according to equipment of the present invention.Based in the equipment of gravity, valve can be low voltage operated valve, such as umbrella valve or duckbill valve.But such valve is usually very thin, thus has the large calorimetric transmission by such valve.Therefore, when applying described thin valve, although valve can the direct flowing of block liquid, be also provided for realizing the structure of thermal-insulation function to avoid under the impact that there is cold liquid heat of cooling liquid and heat cold liquid under the impact that there is hot liquid.Such as, the space of air entrapment can be provided near valve.
Under any circumstance, when applying the invention, realize occurring the flowing of liquid on from boiler to the direction of cold liquid system, and hot liquid and cold fluid isolation.As a kind of favourable outcome, but no longer occur that the user of equipment expects that the water being in environment temperature in cold liquid system finds that there is the such worry of a certain amount of warm water.In addition, reduce the energy ezpenditure of boiler, because the temperature in the boiler side of equipment no longer reduces constantly under the impact mutual with the liquid carrying out self cooling liquid system.Another favourable outcome improving the isolation of hot liquid and cold liquid is that the phenomenon being called biological attachment can not appear in cold liquid system, or at least slows down to such degree and make the situation that do not occur posing a health risk in the normal use of equipment according to the present invention.
About the possibility of the check valve had in a device for anti-backflow, notice that such valve can be the type being suitable for opening under the impact of fluid pressure.This option is requiring to allow according to particularly favourable in the simple as far as possible situation of equipment de-sign of the present invention, and wherein without the need to having the valve of following movable part, these movable parts need to be placed in open position or closing position on one's own initiative by microcontroller etc.
Equipment according to the present invention advantageously comprises the air trapping space being positioned at boiler upstream position.In this way, produce following air-lock, this air-lock can be positioned to the cold fluid isolation in the hot liquid in boiler and cold liquid system.Preferably, the design in air trapping space makes at equipment by air entrapment automatic during liquid filling.Under these circumstances, as long as equipment is by liquid filling, a certain amount of air just will remain in equipment.In addition, just air-lock is rebuild whenever emptying with when refilling the equipment comprising boiler.
Within the scope of the invention, cold liquid system can directly be connected mutually with boiler, but also likely allow equipment according to the present invention comprise the pipe-line system cold liquid system and boiler interconnected, this pipe-line system is included in the pipeline extended between cold liquid system and boiler, and wherein air trapping space is present in having in the part of the cross-sectional area larger than adjacent part of pipeline.In such an arrangement, all kinds of practical step can be taked to ensure that air remaines in the qualifying part of pipeline, wherein likely utilize barrier to be present in the fact as upper/lower positions, the part with comparatively large cross-sectional area of pipeline is connected to the part with small cross sectional in these positions.
In a practical embodiments, it is that block the wall in access air trapping space, for preventing liquid to fill air trapping space from cold liquid system side device that this equipment can comprise form.The physical barriers at least partially had in the device for defining air trapping space a kind ofly cannot arrive air trapping space based on liquid and ensure that air is held in the appropriate ways in this space.
According to the first possibility, the pipe-line system being included in the pipeline extended between cold liquid system and boiler is present in this equipment, wherein pipe component is arranged in pipeline, and wherein at least end of pipe component, the cross-sectional area that is specially the end being positioned at boiler side are less than the cross-sectional area of the position that pipeline exists in the end of pipe component.In this case, the wall of the end of pipe component exists during operation between region (comprising the air trapping space between the wall of the end being present in pipe component and the wall of pipeline) that the region (i.e. the inside of pipe component) of liquid flow and liquid cannot arrive and forms physical barriers.
Preferably, the wall of pipe component is thin-walled and comprises soft material, thus the end of pipe component can be used as can under the impact of very low-pressure (such as, leading in based on the equipment of gravity pressure) check valve of open and close.The embodiment being included in the pipe component extended in pipeline has compact and advantage that is simple designs, and has useful valve function and air trapping function simultaneously, thus prevents liquid to be back to cold liquid system from boiler, and also prevents the heat transmission by valve.
According to having the second possibility of existing in this concept of wall for blocking access air trapping space, air trapping space is limited by the inner space of the hollow unit for holding air.In this case, the wall of hollow unit forms the wall preventing liquid filling air trapping space.Hollow unit arbitrarily can be arranged in the part with the cross-sectional area larger than adjacent part of the pipeline of pipe-line system, and wherein the cross-sectional area of hollow unit is greater than the cross-sectional area of the adjacent part of pipeline.Based on the difference of cross-sectional area size, hollow unit can not be allowed to overflow from the qualifying part of pipeline with the air be accommodated therein.In addition, due to the random layout of hollow unit, so hollow unit can perform valve function.Specifically, prevent from being back to cold liquid system from boiler when hollow unit blocks the opening be present between the part with comparatively large cross-sectional area of pipeline and the part with small cross sectional of pipeline, and hollow unit can flow to the pressure of boiler from cold liquid system at liquid impact under float on the position had in the part of comparatively large cross-sectional area of pipeline, thus no longer blocking of said openings.
Hollow unit can have any suitable shape for keeping a certain amount of air.Such as, hollow unit can be spherical and completely closed, or can be cheese, and wherein the side of hollow unit, the side be specially bottom hollow unit are open.
According to another option be suitable for when equipment comprises independent valve except hollow unit, hollow unit can be connected to valve.In this configuration, make to transmit minimum by the heat of valve, because just there is the isolated effect of air in the position of valve.
Noting when applying hollow unit, especially when hollow unit closes completely, this component can be made to be filled by another the suitable heat-insulating material being different from air.
When this equipment has air trapping space, for generation of non-return valve function and another the favourable possibility strengthening the thermal-insulation function in space is that application is for the device by being transformed into consecutive drop to the liquid flow of boiler from cold liquid system.Specifically, utilize described device, physical contact between the liquid realizing the opposite side of the liquid-to-air detention space of the side in air trapping space, thus to the full extent thermal insulation occurs.In addition, cannot occur that liquid flows to cold liquid system from boiler, because the return route of air bound liquid.
Particularly useful for liquid flow being transformed into being applied in following configuration of the device of consecutive drop, cold liquid system is arranged in the horizontal plane higher than boiler in the configuration, and in the configuration this Plant arrangement above air trapping space.Then drop can fall to the pipeline leading to boiler from this device simply, thus passes through air trapping space.In a practical embodiments, the device for liquid flow being transformed into consecutive drop comprises the multiple thin slices, straw, fiber etc. that have very little space, extension adjacent one another are therebetween.An advantage of application fiber is that this device also can have the function of decontaminating liquid.
For actual cause, equipment is advantageously equipped to the conduit be arranged between cold liquid system and boiler, this conduit will be used for the air being filled with the part of liquid of remover apparatus.Usually, described deaeration conduit has small diameter.When air trapping space be present in according in equipment of the present invention time, this space may be present in cold liquid system, wherein the end of deaeration conduit extends in air trapping space, in addition, in this case, equipment can comprise two check valves, one of them check valve is arranged in the position in pipeline, and for allowing liquid being flowed from cold liquid system to the direction of boiler by pipeline, and for blocking flowing in the other direction, and wherein another check valve is arranged in the end be present in cold liquid system of deaeration conduit, and flowed from boiler to the direction of cold liquid system by deaeration conduit for allowing liquid, and for blocking flowing in the other direction.In this arrangement, the interface between hot liquid and cold liquid is present in the end of deaeration conduit.Especially, this provide following advantage, the position that the hot liquid not allowing the user of equipment to know to see equipment and cold liquid are isolated from each other, it may contribute to the evaluation of user to equipment with regard to concern health, because can expect that the pollutant of such as fungi, incrustation scale etc. is mainly present in these privileged sites.
In the device in accordance with the invention, boiler can be positioned the horizontal plane lower than cold liquid system at least partly.In this regard, notice that this equipment can be the equipment based on gravity that liquid displacement wherein only occurs under the influence of gravity.A concrete aspect based on the equipment of gravity is that such equipment does not have pump etc. can work yet, thus can save energy and space, and this can be favourable in the various set application of this equipment.Based in the equipment of gravity, in the ducted situation that check valve is present in pipe-line system, if air trapping is spatially located between valve and boiler, be favourable.When air trapping space is present in the boiler side of valve, the liquid in boiler be held in the highest may temperature because hinder the hot transport process being arranged in the element beyond valve to valve and equipment based on the isolated effect in air trapping space.
From the hereafter specific descriptions of the multiple embodiments to equipment according to the present invention, these aspects will be illustrated with reference to this description in clear above and other aspect of the present invention, wherein attach most importance to the part that wherein there is air trapping space of this equipment.

Detailed description of the invention
Fig. 1 diagrammatically illustrates multiple parts of the first embodiment according to equipment 1 of the present invention.In this example, equipment 1 is the equipment for purifying waste water, but this does not change the present invention and can be suitable in the field of the equipment of other types that this is true yet.
Equipment 1 comprises the storage box 2 for holding water and the boiler 3 for holding also heating water.Fig. 1 illustrates storage box 2 and boiler 3, relevant with the normal orientation of equipment 1 location, and shows boiler 3 and be positioned the horizontal plane lower than storage box 2.Storage box 2 is communicated with by pipeline 4 with boiler 3, and this pipeline 4 extends from storage box 2 to boiler 3 and has substantially vertically-oriented in the example shown.In addition, in the example shown, blast pipe 5 is arranged between storage box 2 and boiler 3.
The filling process of boiler 3 occurs under the influence of gravity, and wherein water flows to boiler 3 by pipeline 4 from storage box 2.Boiler 3 has the suitable heater for heating water and/or boil water.
Equipment 1 has two taps 6,7, be namely connected to storage box 2 and be applicable to supply from the water of storage box 2 tap 6 and be connected to boiler 3 and be applicable to supply from the tap 7 of the water of boiler 3.The user of equipment 1 uses the first tap 6 when hope obtains from equipment 1 water being in environment temperature, and user uses the second tap 7 when hope obtains hot water from equipment 1.
If the present invention relates to avoid pipeline 4 to open under all circumstances simply, the hot water of generation is undesirably shifted to storage box 2 by pipeline 4 and cold water undesirably shifts to by pipeline 4 measure that boiler 3 is target.Specifically, according to the present invention, take measures to avoid water to be refluxed (namely flowing back into storage box 2 from boiler 3) by pipeline 4, and so that the position between storage box 2 and boiler 3 produces thermal insulation.
Fig. 2 shows the details (i.e. the part 8 with the cross-sectional area larger than adjacent part of pipeline 4) of Fig. 1, and thus illustrate a kind of realize as mention in previous paragraph avoid water reflux and the first example of the mode of the function that hot water and cold (environment) water are completely cut off.In the example shown, thin hose member 9 is arranged in the part 8 (hereafter will be referred to as to amplify pipe section 8) with relatively large cross-sectional area of pipeline 4.One end of pipe component 9 is positioned at the storage box side of amplifying pipe section 8, and the other end of pipe component 9 is positioned at the boiler side of amplifying pipe section 8.In boiler side, pipe component 9 has conical by its shape, and wherein the end 10 of pipe component 9 is normally closed.Only between the side and opposite side of normal-closed end 10 pressure differential impact under, pipe component 9 is just opened, and allows water to pass through.
In the equipment 1 for purifying waste water, apply pressure from storage box 2 side under the influence of gravity.When pipe component 9 is opened under the impact of this pressure, water flows to boiler 3 from storage box 2.Once ease off the pressure, again closedly under the impact that pipe component 9 tilts at the material of pipe component 9 present original closing position and/or applied pressure on the end 10 of pipe component 9 with a certain amount of air by having the function of surrounding this end 10, this will be illustrated subsequently.Under any circumstance, in the closure state of pipe component 9, cannot occur that water is back to storage box 2 from boiler 3.Therefore, pipe component 9 serves as and is suitable for only allowing water flow to boiler 3 from storage box 2 and block the check valve passed through in the opposite direction.Specifically, pipe component 9 serves as so-called duckbill valve.
In addition, due to the conical by its shape of pipe component 9, so in amplification pipe section 8, namely obtain air trapping space 11 at such as upper/lower positions, there is the space between the outer wall and the inwall of pipeline 4 of pipe component 9 in this position.The water flowing to boiler 3 from storage box 2 cannot fill air trapping space 11, because pipe component 9 guides water by amplifying pipe section 8, and just to remain at air trapping space 11 IT the air amplified in pipe section 8 once pad device 1, wherein air can not be overflowed by the wall of pipeline 4, the wall of pipe component 9 and the water seal in boiler side.
Based on the existence of air in air trapping space 11, produce insulation effect, wherein this isolated relatively cold water be present in storage box side is with between the relative hot water in boiler side.In this way, in fact the water temperature realized in storage box 2 is not subject to the Water Temperature in boiler 3, and the water temperature in boiler 3 is in fact by the Water Temperature in storage box 2.
First, equipment 1 according to the present invention can provide the water purifying function identical with the conventional equipment for purifying waste water and water memory function.Because pipe component 9 can not be opened in low pressure, so in fact do not affect water to flow to boiler 3 from storage box 2.The advantageous effects of the design of pipe component 9 relates to the valve function of anti-sealing backflow and makes the water in storage box side and the heat between the water of boiler side transmit minimized thermal-insulation function.
Within the scope of the invention, there are the many alternative for realizing valve function and thermal-insulation function as described in the text.Fig. 3-Fig. 9 is for illustrating the multiple alternative in these alternative.
In figure 3, the first alternative is shown.According to this alternative, pipe component 9 be rigidity and without conical by its shape, and valve function can not be performed.Therefore, provide independent valve 13 in the storage box side of pipe component 9, this valve 13 can be relatively simple valve, such as the umbrella valve that can open under the impact of low pressure.As the situation of embodiment described based on Fig. 2, air trapping space 11 is present between the outer wall of pipe component 9 and the inwall of pipeline 4 for realizing thermal-insulation function in the position of amplifying pipe section 8.
In the diagram, the second alternative is shown.According to this alternative, without pipe component 9, but air trapping space 11 is made up of the top of amplifying pipe section 8 simply.In the position be connected with the adjacent pipe sections 12 in storage box side from amplification pipe section 8, valve 13 is provided, this valve can allow water to be transmitted to boiler 3 by air trapping space 11 from storage box 2, and this route can be blocked in the opposite direction, thus air can not be allowed to overflow from air trapping space 11.Such as, valve 13 is solenoid valves of electricity operation.In this case, the running of valve 13 does not directly depend on the pressure leading in the both sides of valve 13, and ensures the appropriate operation of valve 13 in the situation that pressure ratio is high in based on the equipment 1 of gravity yet.
In Figure 5, the 3rd alternative is shown.According to this alternative, umbrella valve 13 is arranged in and amplifies the storage box side of pipe section 8, and air trapping space 11 is being just positioned at below valve 13 from storage box side to during boiler side.
In figure 6, the 4th alternative is shown.According to this alternative, just like umbrella valve 13 such in the 3rd alternative.But, be connected to valve 13, the form of the hollow unit 14 that holds air or another heat-insulating material provides air trapping space 11.
In the figure 7, the 5th alternative is shown.According to this alternative, apply a kind of equipment 15 for current being transformed into water droplet.In the example shown, this equipment 15 comprises relative to each other with multiple thin slices, straw, fiber etc. that relatively little distance extends.The application of fiber in drip set 15 is favourable, because based on such application, likely is also used for purifying waste water by drip set 15.
Drip set 15 is arranged near the storage box side of amplification pipe section 8, and wherein air trapping space 11 is present in the top of amplifying pipe section 8.Under the impact from storage box 2 side applied pressure, supply current to drip set 15, and generate water droplet by equipment 15 along with water, these drops fall to the boiler side of amplifying pipe section 8.By supplying water with the form of drop to boiler 3, the water realized in storage box side directly contacts with nothing between the water of boiler side, thus strengthens the thermal-insulation function in air trapping space 11 even further.There is provided the fact of certain flow resistance based on drip set 15, drip set 15 has valve function.But, if wished, then likely there is additional valve 13, such as umbrella valve as shown in Figure 7.
In fig. 8, the 6th alternative is shown.According to this alternative, the hollow unit 14 holding air or another heat-insulating material is arranged in and amplifies in pipe section 8, and this hollow unit 14 free-floating is in amplification pipe section 8.In the example shown, hollow unit 14 is spherical, and wherein the cross-sectional area of hollow unit 14 is less than the cross-sectional area amplifying pipe section 8, and is greater than the cross-sectional area of adjacent pipe sections 12,16.In this way, ensure that hollow unit 14 can not be overflowed from amplification pipe section 8.Amplifying the storage box side of pipe section 8, pipeline 4 is tapered, thus hollow unit 14 leads to smoothly as upper/lower positions, and this position is used for blocking when not applying pressure from amplifying pipe section 8 passing through to the adjacent pipe sections 12 in storage box side.But, when the pressure is exerted, hollow unit 14 is shifted a bit, thus allows water to pass through between hollow unit 14 and the inwall of pipeline 4.According to above description, hollow unit 14 has valve function.But, if wished, then likely there is additional valve 13, such as umbrella valve as shown in Figure 8.
In fig .9, the 7th alternative is shown.According to this alternative, apply another kind of hollow unit, namely open in bottom side cheese hollow unit 17.Along with air rises in water, even if there is open sides, still without the risk that air is overflowed from hollow unit 17.
