Description
Technical field
The utility model relates to biomass fuel thermal decomposition equipment, specifically relates to refer to a kind of biomass pyrolysis furnace.
Background technology
The direct-heating type pyrolysis oven is the body of heater of a sealing, prevents the oxidative pyrolysis stove (patent No.: CN200920062938.0), with top all imporosities, the bottom has the slit, is used for draining steam, wood vinegar, wood tar oil and wood gas etc. all around as a kind of.Biomass are the high renewable energy sources of a kind of water cut, begin in pyrolysis, at first are the moisture in the evaporation biomass, after water becomes steam, through thick biomass; Could get into flue and discharge, owing to receive the resistance of thick biomass layer, water vapor is difficult for passing through, and along with the prolongation of time, the temperature of igniting place constantly rises; To more than 600 ℃, at this moment produce a large amount of water vapors, wood vinegar gas, wood tar oil gas and wood gas etc., cause furnace pressure to raise, and wood gas is directly proportional with temperature and pressure, because exhaust is not smooth; Pyrolysis zone igniting place temperature continues to raise, and furnace pressure is also along with rising, and the pyrolysis direction develops towards producing the wood gas direction in the stove, and a large amount of charcoals and wood tar oil change into wood gas; The wood gas calorific value is low, is a kind of non-condensable gases, have to be drained contaminate environment; Waste energy, although pyrolysis oven igniting place temperature more than 600 ℃, is not still evaporated and leave igniting place biomass moisture far away, for exhaust; Often will open bell, prize biomass with iron staff, wood tar oil gas and wood gas in the boiler face burning, bring danger to the operative employee rapidly; Simultaneously, a large amount of inflammable gass are drained, and have wasted the energy, general whenever will prize once at a distance from 4 hours.And pyrolysis temperature is different, and pressure is different, and the charcoal of generation, wood vinegar, wood tar oil and wood gas are different.Under normal pressure, per 100 kilograms of absolutely dry woods char yield in the time of 300 ℃ is 53 kilograms, and wood gas has only 5.6 cubic metres; Calorific value is 6594KJ/M3, and the wood gas total heat is 36926KJ, and char yield is 28.6 kilograms in the time of 600 ℃; Wood gas has 14.3 cubic metres, and calorific value is 15198KJ/M3, and the wood gas total heating value is 217331KJ; When being 300 ℃ 5.8 times, " wooden castoff regenerative recycle utilization " P32 of Chemical Industry Press.Wood tar oil and temperature and pressure are inversely proportional to, and temperature is high more, and produce oil is few more, and pressure is high more, and produce oil is few more.In process of production, one is long 1 meter, wide 1 meter and high 1 meter pyrolysis oven, and the biomass moisture of 1 cubic metre of volume of evaporation is generally wanted more than 80 hour to pyrolysis completion charcoal and oil.And water vapor and wood tar oil gas enter condensation from flue in the lump, contain a large amount of water vapors in the wood tar oil.Biomass charcoal and wood tar oil yield poorly.Draw through in a few years production, water cut is that 1 ton of xylophyta of 25% could produce 0.15 ton of charcoal and 2 kilograms of wood tar oil, and a large amount of charcoal fuel become wood gas and wood vinegar; And wood gas is a kind of low-grade fuel; Generally to the sky discharging, the commodity value of wood vinegar is low, utilizes few.This biomass fuel thermal decomposition equipment has following deficiency: 1. will prize once in every separated several hours, labour intensity is big, and is dangerous; 2. the biomass pyrolytic time is long, production efficiency is low, and production cost is high; 3. biomass charcoal and wood tar oil output are few, and a large amount of charcoal fuel become wood gas and wood vinegar, and wastage of material is big.
Past is vertical setting separating wood tar oil with the regenerating column that wood gas adopts often; (patent No.: the regenerating column of introducing CN200920062939.5) is a metal cylinder like a kind of environment-friendly type pyrolysis oven; Metal cylinder is sealed up and down; The many metal hollow pipes of middle welding, the higher authorities of metal cylinder weld cold water pipe, following welding heat water pipe of metal cylinder.The flue gas that large flue comes out passes in the open tube of regenerating column, wood tar oil, and wood vinegar and water are cooled, and wood gas is then discharged.The bottom of regenerating column is provided with a wood tar oil pond.In order to guarantee cooling performance, often increase regenerating column, about 20～50 meters, since short at the bottom of the tower with the distance on ground, in case the pipeline of regenerating column is stopped up by wood tar oil, be not easy to use the instrument dredging pipeline.
The applicant's utility model patent ZL201120008867.3 discloses a kind of biomass pyrolysis furnace, and this pyrolysis oven is provided with the steam discharge layer between flue and furnace shell inwall, and air gets in the flue through inlet pipe; Because the flue wall is mesh-structured, behind the air admission, preferentially can be by near the wood utilization inlet pipe; Therefore leave inlet pipe position far away slightly because air rarefaction; Pyrolysis is insufficient, and near the excessively pyrolysis easily inlet pipe influences carbon yield.
