Wherein, one-level water-cooled lock hopper, two-stage water-cooling lock hopper are jacket type can-like structure, chuck internal circulation cooling water, tank interior circulation lime-ash.
Wherein, the first high temperature cut-off valve is Pneumatic high temperature gate valve, and the second high temperature cut-off valve is electric high-temperature gate valve；First batcher is that water-cooled locks gas batcher, and the second batcher is electric lock pneumatic batcher.
Wherein, the dust-exhausting port of sack cleaner connects downtake pipe, and downtake pipe connects air-introduced machine, and air-introduced machine connects second exhaust pipe.
Below, it is as follows that the present invention is described in detail:
The top of one-level water-cooled lock hopper is connected with fluidized-bed gasification furnace burner hearth by Pneumatic high temperature gate valve, its closing primarily serving the purpose of lime-ash and precooling, and bottom is connected with Pneumatic high temperature gate valve by flange and bolt and is switched to two-stage water-cooling lock hopper.
Because gasification furnace gasification does not allow contact with outside air, so it is unaffected for ensureing the gasification of gasification furnace, during system work, upper and lower two the Pneumatic high temperature gate valves of one-level water-cooled lock hopper can not be opened simultaneously, the effect one that two-stage water-cooling lock hopper plays is to precool lime-ash, two is to play sealing process, two-stage water-cooling lock hopper bottom is attached with water-cooled lock gas batcher and electric high-temperature gate valve by flange and bolt, and electric high-temperature gate valve is in order to close down the slag input of barrel slag cooler.
Water-cooled lock gas batcher itself has water cooling function, can be high temperature resistant, the even feeding of lime-ash can be realized, and play certain every pressure effect, make the lime-ash pressure in secondary latch bucket will not be passed directly into barrel slag cooler, therefore lime-ash lag cooler will not coking or blocking, barrel slag cooler also will not produce Lou slag phenomenon.
Electric high-temperature gate valve bottom arranges expansion bellow, and in order to absorb the thermal expansion amount of two-stage water-cooled lock hopper, expansion bellow lower end is connected with barrel slag cooler；nullRed-hot lime-ash is cooled down by barrel slag cooler by the form of indirect water-cooling，And lime-ash is carried to slag notch from slag inlet，Lime-ash is after supercooling，Drain into the belt conveyor being connected with barrel slag cooler and transport boiler room，Enter at barrel slag cooler、Slag output end is respectively equipped with a negative-pressure air duct，And be connected with the second induced duct after converging into a road，Air port at one is had above secondary latch bucket，And be connected with the second induced duct，Second induced duct and the second induced duct are all connected to bellows top，Bellows use rustless steel to make，Can tolerate higher temperature，Effect is to be mixed by two-way dusty gas，And from bellows bottom, mixed dusty gas is caused sack cleaner by taking out dirt pipe，Because high-temperature gas density is little，And bellows use the arrangement form of top air intake bottom air-out，Therefore be easy to high-temperature dusty gas and the most sufficiently mix，Sack cleaner effect is to filter gas，Dusty gas is made to be purified，Electric lock pneumatic batcher it is connected to below the ash bucket of sack cleaner，The dust etc. that can be collected by sack cleaner uniformly discharges ash bucket，Electric lock pneumatic batcher is connected with ash releasing tube，The ash that ash releasing tube is discharged is connected to belt conveyor and transports boiler room.And the gas after sack cleaner filters passes sequentially through downtake pipe, air-introduced machine, second exhaust pipe etc. and drains into air, air-introduced machine provides the kinetic energy in whole gas flow.
During system work, one-level water-cooled lock hopper, two-stage water-cooling lock hopper, water-cooled and electric lock pneumatic batcher, barrel slag cooler are all passed through cooling water, water source is retrieved from steam generator system and condenses water, can introduce from low-temperature level low-pressure heater, returns high-temperature level low-pressure heater or oxygen-eliminating device.

Because the lime-ash in one-level water-cooled lock hopper, two-stage water-cooling lock hopper exists higher malleation, therefore in order to make lime-ash be unlikely to present spray regime to cause lag cooler that leakage slag phenomenon occurs, the present invention is provided above negative pressure air port in two-stage water-cooling lock hopper, this negative pressure air port is connected by the second induced duct with bellows top, lock hopper internal pressure can be greatly reduced by negative pressure wind, thus alleviating the seal pressure of barrel slag cooler, negative pressure wind also functions to certain cooling effect simultaneously.
The slag input end of barrel slag cooler and slag output end are provided with negative-pressure air duct and converge into a road, in order to cold slag machine drum body is internally formed negative pressure state, thus lime-ash will not produce leakage slag phenomenon at the place of being association of activity and inertia of barrel slag cooler, slag input end negative pressure wind temperature is higher, and slag output end negative pressure wind temperature is relatively low.
Preferably, two sections of negative-pressure air ducts are respectively provided with manually or electrically air door, the negative pressure wind flow in scalable every section negative-pressure air duct, reach to adjust the effect of whole negative pressure wind temperature.
The tolerable temperature of bags in bag-type dust remover is 250 DEG C, but the dusty gas temperature about 300 DEG C got rid of in secondary latch bucket, already more than the tolerance of sack cleaner, and lime-ash can be cooled to 80 DEG C because of itself by barrel slag cooler, the negative pressure wind of its slag input end and slag output end is all from surrounding, therefore the dusty gas temperature after barrel slag cooler two ends negative pressure wind converges is about 100-120 DEG C, therefore when dusty gas herein also causes bellows top with the dusty gas in secondary latch bucket after inner bellows mixes, dusty gas temperature can be down to less than 200 DEG C, fully meet the service requirement of sack cleaner, so that the reliability of this system is substantially improved, life-span significantly extends.
When the mixed gas in bellows is directed to sack cleaner from bellows bottom, granule dust big, heavy, owing to the effect of gravity settles down, fall into ash bucket, gas containing relatively fine dust is when by cloth bag, dust also can be by by detention, gas is made to be purified, purified gas passes sequentially through downtake pipe, air-introduced machine, second exhaust pipe etc. and drains in atmospheric environment, the dust being filtered then electric lock pneumatic batcher and ash releasing tube by ash bucket bottom drains into belt conveyor, and environment will not be caused any pollution by whole process.In lime-ash cooling procedure, the heat of the lime-ash water that is cooled fully absorbs, and by heat recovery to steam generator system, thus can improve the thermal efficiency of boiler, reduces boiler coal consumption, energy-conserving and environment-protective.
