Description
Technical field
The utility model belongs to producer gas generator field, particularly fluidized-bed gasification furnace.
Background technology
Along with the raising day by day of environmental requirement, forbid that directly coal-fired scope is more and more wider, clean fuel will be used widely.Present stage, available clean fuel mainly contained fuel oil, Sweet natural gas, coke gas, producer gas and liquefied petroleum gas (LPG) etc., and wherein producer gas is that the easiest producing also is most economical a kind of fuel.Present coal gas device for making is based on fixed bed coal gas producer, the fluidized bed coal gas producer is the novel furnace that grew up in recent years, it is strong to have fuel tolerance, vaporization efficiency advantages of higher, the heating gas that producer produces are directly supplied with roasting kiln and are used after the separator dedusting, system is simple, not only integrated heat efficiency height, and obnoxious flavour content is few, compliance with environmental protection requirements.
But slagging tap of fluidized-bed gasification furnace (fluidized bed coal gas producer) is partly with higher heat at present, do not recycle well.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of waste heat recovery fluidized-bed gasification furnace, and the waste heat of slag is recycled, and saves heat energy.
The utility model waste heat recovery fluidized-bed gasification furnace, comprise body of heater, body of heater has the jacketed type vapour generator, the body of heater bottom is an air compartment, be provided with the cone air distribution plate in the air compartment, air compartment connects air intlet, be provided with opening for feed in the body of heater middle and lower part, the furnace bottom bottom is provided with the spiral skim gate, has on the skim gate except that cinder notch, and upper of furnace body connects gas exit by fly-ash separator, the body that it is characterized in that described spiral skim gate has water jacket outward, water jacket one end has cooling water inlet, and the other end has hot water outlet, and hot water outlet is connected with jacketed type vapour generator import on the body of heater.
Spiral skim gate of the present utility model adopts the water-cooled skim gate, by being arranged on the waste heat that water jacket on the spiral skim gate can absorb slag effectively, be used to the jacketed type vapour generator of oven body part after water in the water jacket is heated, thereby save heat energy.
Air distribution plate described in the utility model is provided with porous notch cuttype nozzle.This nozzle one is to produce high velocity air, fire coal blown forms suspension fluidisation state of combustion, and the 2nd, be not easy to stop up, tiny coal ash enters nozzle, because of the nozzle lower space is bigger, is difficult for stopping up.
The opening for feed of the utility model body of heater middle and lower part preferably connects acclivitous screw stoker, realizes the vapourizing furnace automatic stoking.
Advantage of the present utility model:
The waste heat recovery fluidized-bed gasification furnace has obvious superiority than traditional type fluidized-bed gasification furnace and fixed bed water-gas generators, and it has opened up a new way for China's coal gasification and waste heat recovery.Owing to can use various fine coal, be convenient to gather materials on the spot, make full use of local coal resources; This furnaceman's process flow is simple, reduced investment, easy to operate, be easy to automatization; In this stove production process, produce seldom tar and phenols, purify easyly, be easy to reach environmental requirement; This stove is provided with afterheat of slags and reclaims skim gate, can save heat energy.Therefore, the waste heat recovery fluidized-bed gasification furnace is traditional type fluidized-bed gasification furnace and fixed bed water-gas generators ideal substitute products, in China's broad market prospect.
