Description
Technical field
The utility model relates to industrial equipment for gasification, especially relate to can heating gas top-suction type biomass gasification furnace.
Background technology
In recent years, frequently there is haze weather in the multiple cities of China and area, and how PM2.5 continues to exceed standard.Serious atmospheric pollution, the industrial development road of " high pollution, high energy consumption, the maximum discharge " walked for many years to China has been beaten alarm bell.Wherein to discharge the topsoil causing be a major reason to coal-burned industrial boiler.Reduce the use of the fossil energies such as coal, oil, find and utilize clean energy, can reduce like this pollution level of atmosphere, reduce PM2.5 index.
Biomass energy is known as reproducible clean energy by countries in the world, and China has a large amount of agricultural crop straws and forestry waste every year, for development China biomass energy provides raw material basis.
Biomass are used as the energy and use and be mainly used in the fuel of Industrial Boiler, and combustion system has biomass molding fuel burning, biomass gasification fired etc.Because country requires to improve constantly to Air Pollutant Emission, fume emission index when biomass molding fuel burning is difficult to can meet the requirement of environmental protection.Biomass gasification fired is, by biomass gasification equipment, biomass material is transformed into biological fuel gas.The flue dust ratio discharging when biomass fuel gas firing is easier to meet the requirement of environmental protection.Biomass gasification burning has hot combustion gas and cooling combustion gas.Biological fuel gas for combustion of industrial boiler is generally hot combustion gas, and boiler combustion is directly supplied with in the hot combustion gas that gasifying biomass produces.The biomass gasifying furnace adopting mainly contains downdraft and updraft type.Top-suction type biomass gasification furnace can produce more tar and some dusts in the time of gasification, the combustion gas that updraft type vapourizing furnace produces will be passed the bed of material, fuel gas temperature can be lower, gas outlet is generally all at top of gasification furnace or upper lateral part, make that often Yin Wendu is lower has a large amount of gaseous state tar and in pipeline, condense into tar liquid from vapourizing furnace hot combustion gas out, can cause like this biomass gasification equipment normally not move, tar liquid is difficult to process, simultaneously because the calorific value of separating out biomass thermal combustion gas of tar reduces; When dust is many, equally also can affect the normal of vapourizing furnace.The current updraft type biomass gasification technology of this problem not can solve.
Utility model content
The utility model is exactly for the deficiencies in the prior art, and provide the technical scheme of top-suction type biomass gasification furnace that can heating gas, this scheme adopts updraft type structure that can heating gas, the combustion gas that gasification is produced can be heated in the stokehold that goes out to gasify, allow combustion gas keep higher temperature, tar in combustion gas is present in combustion gas in the mode of gaseous state all the time, reduces the generation of dust in gasification simultaneously.
This programme is achieved by the following technical measures:
Top-suction type biomass gasification furnace that can heating gas has outer cylinder body, middle cylindrical shell, inner barrel, inner barrel top is opening for feed, cover plate is arranged at outer cylinder body top, there is thermal insulation layer outer cylinder body inner side, outer cylinder body bottom connects water-cooling jacket, there is gas outlet outer cylinder body middle and lower part, middle cylindrical shell is connected with water-cooling jacket inner side, middle cylindrical shell top is connected with cover plate, one or several ventage is arranged at the top of middle cylindrical shell, there is heat transfer sheet in the outside of middle cylindrical shell, fire grate is positioned at the bottom of water-cooling jacket, fire grate top to water-cooling jacket upper surface is combustion chamber, the top of combustion chamber is vaporizer, vaporizer top is inner barrel lower rim, between inner barrel and middle cylindrical shell, form internal layer passage, between middle cylindrical shell and thermal insulation layer, form outer layer channel, water-cooling jacket connects support platform, under support platform, connect steel column, fire grate below connects ash bucket, there is air intlet the side that goes out ash bucket.
The beneficial effect of this programme can be learnt from the narration of such scheme, comprise outer cylinder body, middle cylindrical shell, inner barrel, between cylindrical shell, form blast tube, the combustion gas that gasification produces flows to gas outlet through blast tube, the lower outside of middle cylindrical shell has heat transfer sheet, gas outlet is in outer cylinder body middle and lower part, make because the middle cylindrical shell downside temperature in when gasification is higher through combustion gas constantly heated, allow combustion gas keep higher temperature, the tar in combustion gas exists in gas mode all the time, has solved the problem that tar is separated out; Although the increase bed of material can reduce the initial temperature of combustion gas, but because the combustion gas of low temperature can be heated to comparatively high temps by middle cylindrical shell bottom, can make like this bed of material thickening of vapourizing furnace, better filteration is played in the combustion gas that gasification is produced, and reduces the generation of dust.This vapourizing furnace can allow the combustion gas producing keep higher temperature to reduce the generation of dust simultaneously, as can be seen here, the utlity model has obvious advanced unusual effect, can solve the existing corresponding problem of current top-suction type biomass gasification furnace, has promotional value.
