Background technology
Biomass gasifying furnace lives through a low ebb in the process promoted, now along with gasification technology is constantly perfect, society is readmitting this technology, particularly gasification technology unique function in refuse treatment, causes the attention of more and more scientific research personnel.
There is the following problem in absorbing biomass gasification furnace traditionally: one is that well how solution does not remove the tar problem in combustion gas; Two is that in the fuel gas buring process of gasification generation, the simple operation of secondary air distribution is too poor; Three is that vapourizing furnace is too high to the humidity requirement of material.
Research proves, the starting point of secondary air distribution is changed into the fuel gas layer of vapourizing furnace, the temperature of combustion gas can be reduced rapidly, remove the portion of water in combustion gas and tar, discharged out of the furnace by tank, has certain effect to solution three problems above-mentioned.
Summary of the invention
The purpose of this utility model is the top-suction type biomass gasification furnace providing a kind of good airproof performance, energy-saving and environmental protection.
For achieving the above object, technical scheme provided by the utility model is: a kind of top-suction type biomass gasification furnace, it includes bell, sealed cistern, blow-off pipe, dirt collecting tank, secondary aid distributing pipe, gas line, stove outer covering, thermal insulation layer, air distribution plate, an electrical ignition element pipe, main blast pipe, gasification blast pipe, stove pin, ash storage box, ash-draining gate, wherein, ash storage box is provided with bottom stove outer covering, ash storage box side sidewall is provided with ash-draining gate, stove outer covering bottom ash storage box extends to form stove pin, be coated with thermal insulation layer in stove outer covering above ash storage box and form furnace chamber, place of furnace chamber bottom centre is provided with air distribution plate, wind distributing hole on air distribution plate is communicated with furnace chamber and ash storage box, bottom furnace chamber, side is provided with an electrical ignition element pipe, side, furnace chamber top is provided with gas line, and opposite side is provided with secondary aid distributing pipe, and the gasification blast pipe of secondary aid distributing pipe and ash storage box side is all connected on main blast pipe, stove outer covering top is provided with sealed cistern, and bell is fastened in sealed cistern and forms water seal, and sealed cistern side is provided with blow-off pipe, and blow-off pipe outlet extends the dirt collecting tank being positioned at stove outer covering outer wall.
Described secondary aid distributing pipe is provided with switch.
Described main blast pipe connecting secondary aid distributing pipe and gasification blast pipe, the cross-sectional area of secondary aid distributing pipe is greater than gasification blast pipe cross-sectional area, and area ratio is λ, 2≤λ≤5.
Described bell is the doline of falling of epirelief, and pitch angle is α, 5
0≤ α≤45
0.
The utility model has the advantage of:
1) secondary air distribution first accesses the fuel gas layer of vapourizing furnace, combustion gas is cooled rapidly in stove, and the coal-tar middle oil and sewage of combustion gas has part wash rice and goes out and flow in tank on bell, reduces the ratio of moisture and tar in combustion gas, is conducive to improving combustion gas quality.The reduction of combustion gas water content, reduces the requirement of vapourizing furnace to humidity of materials naturally.
2) sewage containing tar in tank flows into dirt collecting tank, and the sewage of collection and crushed biomass are again inserted after mixing and stirring airing in vapourizing furnace and gasified, and have good environment protecting.
3) secondary air distribution in stove, will mix process in advance, be conducive to combustion gas with air is fully mixed, and the rapid degree of raising mixed gas, burns more abundant.
