(2.1), in inertial separator, be provided with built-in air preheater, the vapourizing furnace required air is sent into the air compartment of vapourizing furnace fluidized-bed after this air preheater preheating;
(3), constitute multistage gas-purification system by cyclonic separator, Venturi tube, water wash column, send into cyclonic separator through the combustion gas that inertial separator is separated, Venturi tube is sent in combustion gas after the cyclonic separator dust removal process, combustion gas in Venturi tube through the cooling and flush away part tar after send into water wash column, combustion gas in water wash column through further cool off and remove tar after send into gas-holder by induced draft fan;
(4), have the sewage disposal and a recycle system thereof, the waste water of being discharged by Venturi tube and water wash column is pumped into Venturi tube again after treatment tank is handled and water wash column recycles.
The circle fluidized-bed gasification furnace that has built-in fluidized-bed in the system can be in conjunction with constituting integral structure with the inertial separator with built-in air preheater, promptly constitute preheating of air formula circle fluidized-bed gasification furnace, this vapourizing furnace collection gasifying biomass, the multiple function of the flying dust in the combustion gas being separated and the flying dust of separating being back to the vapourizing furnace burning and the air that vapourizing furnace is provided being carried out preheating.
How one of son conspires to create the multistage gas sweetening of carrying out to water wash column in the system as required.
Treatment tank in the system can be done the processing of processes such as waterfall gas, absorption and filtration to the sewage of being discharged by Venturi tube and water wash column, is converted into clean water again and recycles for Venturi tube and water wash column.
Unique design of the present invention, it is wide to have suitability, adjustable extent is big, the characteristics that technical feature is high, it can handle several waste materials individually or simultaneously, comprises wood chip, husk, straw or bagasse etc., day is handled the waste material amount can be from 10 tons to 200 tons, the combustion gas that is produced can be generated electricity hundreds of kW to several thousand kW, and water loss is low, thermo-efficiency height (greater than 16%).
