Description
Technical field
The present invention relates to can the loading machine of vitrified material, it includes the head formed by dismountable slide baffle plate, relates to the facility for melten glass including this type of loading machine, and the method relating to use this type of facility melten glass.
Background technology
In glass-melting furnace, vitrifiable primary material (matieres
Premieres) charging generally by being deposited in glass bath realization by these materials.In there is the smelting furnace being positioned at the normal burner above glass horizontal, need moistening can vitrified material with prevent they by heat furnace gas take away (such as seeing US 3,725 022 and US 6 349 570).But, due to the evaporation of water used, this moistening in advance has high cost in terms of energy consumption.
In addition known recovery comprises the mineral fibres of organic principle (organic bond).But, this reclaims needs to remove organic principle (such as seeing EP 2 072 474) in advance by burning in loading machine the most the latest.But, this type of precombustion in the positive upstream of smelting furnace prevents the moistening before the fibrous material that will reclaim feeds in smelting furnace to them.
Summary of the invention
It is an object of the invention to provide a kind of method for melten glass and facility, it allows to need not any pre-wetting and overcomes the problem that the spreading (volage) to primary material is relevant, and the problems even for primary material to be reclaimed the such as mineral wool comprising vast scale organic material.In the method for the invention, it is not necessary to the primary material that will reclaim is placed among the precombustion step being intended to remove organic material.The method relying on the present invention, can so feed smelting furnace by the glass wool comprising organic bond (even accounting for significant proportion) or asbestos, i.e. do not have precombustion or pre-wet.
This purpose uses following means to realize by comprehensive in the present invention:
-specific loading method relates to feeding under the level of the bath of melted material, is referred to as " feeding at depth " or " submergence charging " later；And
-at the burner of center submergence of melten glass, it is allowed to the burning of the organic principle that primary material to be circulated is concomitantly introduced into.
The most fully spreading can be restricted to vitrified material amount acceptable for the method in depth charging.The organic principle of primary material to be reclaimed be no longer regarded as be melted before debatable factor to be removed, but valuable fuel, which improve the energy budget of the method.Specifically, when the organic material (paper, binding agent, polymer adhesive) being concomitantly introduced into primary material to be reclaimed contacts with the bath of hot glass, pyrolytic reaction and pyrolysis gas is occurred to contact with oxygen and burn.This oxygen may originate from the oxide in glass bath, and the consumption of this oxygen causes again the minimizing of glass bath.During otherwise it may be present in the air above molten glass bath.Certainly, when the ratio of organic material is the biggest, such as oxygen can be continuously fed by oxygen bubbler or oxidation chemistry reagent.
The energy budget of the glass melting process of the present invention is enhanced also by need not fiber or pre-wetting of granule primary material.
As fuel with can the organic principle that is concomitantly introduced into of vitrification primary material use thus in theory permission liquid or solid fuel such as organic waste or biomass substitute usually submerged burner completely the gaseous fuel (natural gas) of the energy be provided.
But, the submergence charging of the present invention creates restriction and causes the problem about safety.If sealing system lost efficacy, under the level of melten glass, the existence of smelting furnace groove tank skin mesopore creates the risk of leakage.Additionally, if loading machine lost efficacy, any work to loading machine will need to make smelting furnace shut down and soar.Finally, loading machine faces the thermal stress more much higher than the thermal stress that the conventional loading machine of charging above the level of glass bath is born.
In the present invention, submergence charging these technical problems caused are solved by the loading machine of a kind of novelty, and this loading machine is particularly suited for the method for the present invention.This loading machine includes that the removable head formed by slide baffle plate, at least its movable part (slide) are passed by the inner conduit system for the coolant that flows.This slide baffle plate allows simply and quickly to close charging hole without making smelting furnace shut down or the groove tank that soars in advance.After closedown, the active cooling of the slide of baffle plate results in the protectiveness duricrust of solid material, and prevents the calorifics deterioration of the head of loading machine.
The dismountable characteristic of loading machine head allows the loading machine with the facility of full groove tank quickly to be removed and/or change.Finally, the head of the cooling of loading machine is inserted between groove tank skin and the nose of loading machine makes loading machine and molten glass bath separate and protected from excessive thermal stress.
The present invention thus relates to a kind of will to be charged to the loading machine in glass melting smelting furnace by vitrified material composition at the level under being positioned at melten glass level, including:
-main body, its have bucket and for conveying can the mechanical system of vitrified material, described system is contained in described bucket；
-there is the head of slide baffle plate, this head is removably secured on the end of bucket；And
-tubular junction divides, and it is fastened on slide baffle plate and is intended to be at least partially inserted in the charging hole in the wall of the groove tank being located at smelting furnace, and this slide baffle plate and this coupling part include the inner conduit system that may be coupled on coolant source.
The main body of the loading machine of the present invention, i.e. comprise for conveying can the bucket of mechanical system of vitrified material, not there is any special mechanical features.Can this mechanical system of vitrified material can be such as piston or one or more worm screw for conveying, the single thread of the main body of loading machine the most for example, routine or double thread extruder.
By the system of the head for cooling down loading machine, main body need not be therefore actively cooled to be protected from the heat impact of smelting furnace.In a preferred embodiment of the invention, bucket or for conveying can the machinery of vitrified material thus the most do not include Active Cooling System, such as may be coupled to the conduit system on coolant source.
The device of supply loading machine is also known (hopper, auxiliary extruder etc.).Loading machine preferably has at least one ingate, is positioned at upstream or the downstream of device for introducing primary material, and this hole will be used for supplying one noble gas (such as nitrogen) during operation.This inert gas flow is intended to purge oxygen and the premature combustion preventing organic principle in the main body of loading machine.
As explained above, the head of loading machine includes slide baffle plate, is preferably fastened directly on the nose of loading machine, and the tubular junction being fastened on slide baffle plate divides.Tubular junction divides preferably substantially coaxial with worm screw, i.e. on the axis of symmetry of the cross section that the rotation axis of worm screw is superimposed upon pipe.In the outer surface of coupling part preferably substantial cylindrical and the charging hole that will be inserted in groove tank skin.Self-evident, the external diameter of coupling part must be the least with the different diameters of charging hole due to this reason, in order to is more easily sealed this and connects.This seals the curing glass layer by being formed on the coupling part of this active cooling and realizes.
The inner surface that tubular junction divides is not preferably strict cylinder, but somewhat opens on the direction of smelting furnace.Coupling part preferably has the inner surface (frustoconical) of general conical, and this taper is widened to the end away from described baffle plate from the end contacted with the formation of slide baffle plate.This widens or opens and is directed primarily to prevent the primary material of partial melting from forming blocking and blocking the opening of coupling part, thus stops freely supplying of the homogeneous of primary material and boundling.
The degree widened of the frustoconical of the inner surface of coupling part, opening angle in other words, preferably between 7 to 13 °, especially between 8 to 12 °, and ideally between 9 to 10 °.
Baffle plate is between the end and coupling part of bucket, and described baffle plate forms the necessary part of the loading machine of the present invention.This baffle plate includes standing part and movable part (slide).
This standing part of baffle plate is detachably fastened on the bucket of loading machine.The hole of baffle plate preferably has the circle of the diameter of the internal diameter divided close to tubular junction, the two part thus form smooth " fuel loading passage ", can the danger that can not blocked by this fuel loading passage of vitrified material.
Additionally, the internal diameter that divides of tubular junction preferably internal diameter with the bucket of loading machine differs at most 20%, especially up to 10%, and desirably less than 5%.
At least this detachable portion of baffle plate includes the inner conduit system that may be coupled on coolant source.During the glass fusion process of the present invention so that the inner conduit system that coolant preferably continuously flows through slide and tubular junction divides.Certainly the standing part by inner conduit system cooling slide baffle plate it is likely to.But when the cooling system of two other parts (movable part, coupling part) is effective, such cooling is not required in that.Although it is required that the active cooling of movable part is only only when flapper closure in principle, for it, preferably even if it is in opening and is also cooled, so that can close very fast and make to forget to turn on cooling system, this can be proved to be harmful.
In order to ensure when needed can be with quick closedown baffle plate, it is important that during operation, the worm screw top of loading machine is not extended past bucket and does not cut the Guan Bi plane of slide baffle plate.
But, mechanical system can be advantageously designed to allow worm screw slide anteroposterior in bucket, in order to can stop during allowing during feeding or after slide flapper closure and reopening that any of fuel loading passage can be forced to release by vitrified material.
The present invention also relates to the facility for melting glass, including loading machine such as above, and there is the glass melting smelting furnace of charging hole, charging hole is positioned in the groove tank skin of smelting furnace under the theoretical level of glass, and this level is limited by the position of the overflow lip of melted material.The tubular junction of loading machine divides and is inserted at least in part in the charging hole of smelting furnace.
The glass melting smelting furnace of this facility can use known heater such as top to install burner, machinery resistor, electrode or submerged burner heating.
In a preferred embodiment, glass melting facility includes being supplied air/gas fuel (such as natural gas) mixture or the submerged burner of oxygen/gaseous fuel mixture.Oxygen/fuel mol ratio can be superstoichiometric, and the amount of oxygen of excess can be adjusted to supply required oxygen and burn the pyrolysis gas formed in charging region.
Finally, the present invention relates to a kind of method for using facility as above to carry out melten glass.
This type of glass melting process includes:
-glass melting smelting furnace can be fed by charging hole by vitrified material composition by the loading machine according to the present invention, charging hole is positioned in the wall of groove tank of smelting furnace, under the level of melten glass, the head of loading machine is divided by tubular junction and is connected on charging hole at the level being positioned at melten glass horizontal down so that can divide entrance smelting furnace via the slide baffle plate opened and tubular junction by vitrified material；And
-cool down the head of loading machine by making coolant flow through the inner conduit system of slide baffle plate, the movable part of inner conduit system especially slide baffle plate and the inner conduit system of coupling part.
Glass melting process is continuous print method.Can the supply of vitrified material and cooling thus simultaneously and preferably implemented continuously by the without interruption of primary material and coolant.
If if it is required, such as loading machine becomes to block or faulty, the existence of detachable slide baffle plate allows to disconnect loading machine and smelting furnace need not shut down and empty.The method of the present invention thus include closing slide baffle plate and being separated by the head of the main body of loading machine with loading machine, head holding is fixedly secured on smelting furnace.
In the case of movable part at slide baffle plate is not therefore actively cooled when the flaps are opened, closing step certainly must be before the initialization of the active cooling making coolant flow or adjoint its is carried out.After closedown, the slide of cooling is covered by one layer of curing glass rapidly, and it forms effective heat ray filter between molten glass bath and slide.
Feed the present invention fusing facility can vitrified material be the most at least partly intended to reclaim can vitrified material, such as mineral fibres or the broken glass that obtains from house refuse.Major part recovering discarded material comprises a certain proportion of organic material, and it need not remove in advance.It is preferably mineral fibres for recycled materials, combines with organic bond alternatively.
By ad hoc structure and the loading method of loading machine, the recycled materials can be at most 100% by constituting by vitrified material.They account for all can vitrified material at least 10% and preferably from 20 to 80%.
The composition of vitrified material can advantageously comprise at least 2 wt%, preferably 5 wt% to 50 wt%, and the organic principle of especially 10 wt% to 40 wt%, this percentage ratio is the mineral relative to supply to loading machine and the gross weight of organic material.
Although the method according to the invention can be implemented by the moistening primary material comprising up to 50 wt% water, one of them benefit is that it actually need not the moistening primary material (see introductory section) for minimizing or the purpose of the spreading preventing granule and fiber.In a preferred embodiment of the method according to the invention, can the composition of vitrified material thus comprise the water less than 5% and the water of preferably less than 3%.
