The secondary water that the present invention has fundamentally stopped in the gasifying biomass cooled coal gas making processes pollutes, and has following advantage:
1, water coolant passes through in the aciculiform pipe, and combustion gas is flowed at the aciculiform ligament, and the combustion gas cooling makes water not have the pollution of secondary water.
2, the water of combustion gas cooling use provides the thermal water source.
3, the blowback system of sweeping accumulates foreign material for each filtration unit cleaning provides convenience.
4, this unit equipment systematize can guarantee that fuel gasification, air feed move continuously, have practiced thrift the labor force.
Agent structure of the present invention is made up of equipment series; Unit is designed with electrical control cubicles; General supply connects each trip switch; Each trip switch connects each motor with electric wire, and tar device, submersible pump, high-pressure hydraulic pump motor formation electrical control system are caught in each switch of electrical control cubicles and feeder, setting gauge, ash hoist, ash ejector, electric fishing.The feeder below is provided with hopper, constitutes feeding system; Rotation setting gauge, rotating metallic net tonifying Qi bucket, ash hoist, lime-ash vision slit, ash ejector constitute fuel gasification and slag-tapping system; Fly-ash separator cyclonic chamber, metal screen constitute combustion gas and dust separation filtering system; Softening water tank injects cold water by submersible pump, and combustion gas is passed through from many aciculiform ligaments, and softening cold water, aciculiform pipe, aciculiform ligament constitute the combustion gas cooling system; Exocoel constitutes the gas-water separation structure in the coarse filtration cloth bag partition; The fine filtering cloth bag can be detained the fine dust that combustion gas is carried in the bag; Cleaner, induced draft fan, recycle valve constitute fuel gas flow, regulation system; Induced draft fan intake valve, blowback sweep into air valve, recycle valve constitutes each filtration unit blowback of combustion gas and sweeps system; Tar device intake valve is caught in electric fishing, exhaust-valve constitutes combustion gas conveying or emptying system; Electric fishing is caught tar device bottom and electric fishing is housed is caught tar device wash water valve, utilizes the high pressure silicon rectifier to remove the micro-tar in the combustion gas; Liquid packing is a whole set of unit outlet combustion gas backspace stream device.
Principle of work of the present invention is following:
The present invention adopts serial equipment comp comprehensive layout; Fuel drops into side-suction type gasification furnace, and setting gauge regularly moves flat the stove fuel, and drives the rotation of wire netting tonifying Qi bucket; Wire netting tonifying Qi bucket has been eradicated fuel threading, bridging, bed of material perforation phenomenon in the process of rotation, stablized combustion gas quality; Ash hoist, the ash ejector that install the side-suction type gasification furnace bottom have guaranteed that gasifying biomass can move continuously; Through having the cyclone dust collector of metal screen, the dust that carries in the combustion gas falls into the fly-ash separator bottom one after another under the suction function of induced draft fan in combustion gas; Refrigerator aciculiform ligament is passed in combustion gas, and the cold water in the aciculiform pipe has reduced the temperature of combustion gas indirectly; When air water separator was passed through in combustion gas, the globule entering cleaner that the moisture in the fuel after the coarse filtration cloth bag is broken away from cooling forms was passed through in combustion gas rapidly; Under the effect of induced draft fan malleation, combustion gas is caught by electric fishing and is gushed out from the liquid packing air outlet after tar device high pressure silicon rectifier is removed tar.
Method of use of the present invention is following:
After starting total power switch, start feeder, setting gauge, induced draft fan, ash hoist, ash ejector, electric fishing successively and catch tar device, submersible pump, high-pressure hydraulic pump.In service continuously for a long time at the gasifying biomass unit when finding that the induced draft fan negative pressure is excessive, is opened exhaust-valve; Close electric fishing and catch tar device intake valve, open blowback and sweep into air valve, close the induced draft fan intake valve; Open the fly-ash separator wash water valve; Close exhaust-valve, can purge each filtration unit before the induced draft fan and take out stains, just can recover the present invention after each filtration unit is unobstructed and normally move.
