Description
Technical field
The utility model relates to living beings gasification field, and refering in particular to is a kind of small-sized household biomass gasifying furnace.
Background technology
Encourage to clean, develop efficiently bio-fuel, the encourage growth energy crop has become the fundamental state policy of China, the Party Central Committee repeatedly clearly will carry forward vigorously energy savings hereof, fully develop regenerative resource, particularly strengthen the rural energy construction paces energetically, development is fit to the clean energy resource of rural area characteristics.And biomass gasification technology is with the biomass material heating, under the condition of anoxycausis, makes organic hydrocarbon chain fracture of higher molecular weight, becomes low hydro carbons, CO and hydrogen etc.This method has changed the form of biomass material, use more convenient, and low-grade biomass energy can be converted into high-grade energy, energy conversion efficiency improves a lot than the direct burning of solid-state biomass, biomass energy can realize " zero-emission " of carbon dioxide when being utilized as the energy, help purifying air, keep ecological balance, so biomass gasification technology receives countries in the world government and scientist's concern.
In the last few years, some family expenses or small-sized biomass gasifying furnace device have appearred, as: Chinese patent ZL02277000.3 " producer ", ZL02277525.0 " hand-rail type blanking producer ", ZL01244199.6 " family expenses stalk gasifier ", ZL200520050979.X " biomass gasifying furnace ", ZL200520050980.2 " biomass gasifying furnace igniting and gasification installation ", its structure substantially all comprises body of heater, air-intake device and cooling purifying device.Yet this technology is still not mature enough, wherein there is the problem of two keys all effectively not solved, one is the tar content height, the user just can't use continuing after using a period of time, decoking mode commonly used at present has: washing decoking, Pintsch process decoking, catalysis decoking, the small-sized biomass equipment for gasification is because the low cause of operating cost can't adopt washing decoking and catalysis decoking, and the Pintsch process decoking, can't the reach a high temperature temperature of cracking decoking of small-sized biomass equipment for gasification; Another is exactly that gas heating value is not high, CO content height, adopts steam as gasifying agent individually, the supply control difficulty of gasifying agent, so some product just only with air as gasifying agent, so just reduced the content of hydrogen in the gas.
Summary of the invention
For fear of with overcome above-mentioned deficiency, the purpose of this utility model is at the deficiency of prior art and innovative design goes out a kind of integral design, integrated assembling, and the tar problem can thoroughly solve, gasifying agent is controlled automatically, the high a kind of small-sized household biomass gasifying furnace of hydrogen content in the combustible gas.
The realization the technical solution of the utility model is:
A kind of small-sized household biomass gasifying furnace, comprise: grey chamber, fire grate, wind is chewed, flame retardant coating, burner hearth, bell, clarifier, wireway, air bleeding valve, cooking stove, valve, the tar recovery tube, body of heater, sewage draining exit, ash discharging hole, blower fan, it is characterized by: body of heater is straight tubbiness, furnace body inside is a flame retardant coating, bottom of furnace body is grey chamber, the ash chamber is provided with ash discharging hole, ash is followed successively by fire grate and Feng Zui above the chamber, wind is chewed with the blower fan on body of heater next door and is linked to each other, clarifier and body of heater are fixed, be positioned at the top of any side of body of heater, clarifier is connected with burner hearth by the tar recovery tube that is positioned at the clarifier bottom, by wireway and chimney, cooking stove connects, chimney, cooking stove is provided with valve, and the valve of cooking stove is positioned on the wireway; But a V-type fluid-tight structure is arranged in the middle of the tar recovery tube; But sewage draining exit is positioned at the bottom of V-type fluid-tight structure; The top of body of heater is the bell that can seal.
The course of work: material is put into burner hearth, cover bell and ash discharging hole, open blower fan, after a few minutes, fuel produces fuel gas by reaction backs such as destructive distillation, pyrolysis, gasification, reduction, at this moment close the air bleeding valve on the chimney, institute's aerogenesis body is lighted in the gas-cooker and can be used through delivering to behind the purification utensil.Living beings are in the process of anoxycausis gasification, and water in the combustible gas and tar just enter under the condensation in clarifier and participates in reaction in the burner hearth, and water participates in gasification reaction as gasifying agent, while tar in burner hearth by high temperature pyrolysis.In the use, according to required gas quantity, as long as the corresponding rotating speed of regulating blower fan.After cooking is finished, cut off blower fan, close gas-cooker, open the air bleeding valve on the chimney.The lime-ash that is produced in the burner hearth is regularly discharged by ash discharging hole.
The utility model compared with prior art has following outstanding advantage:
(1) tar that condenses in the clarifier directly turns back to by the tar recovery tube and carries out pyrolytic gasification once more in the burner hearth, thoroughly solved the problem of small evaporator device tar, avoided polluting once more, in addition, tar generally occupies 10%～18% energy, by pyrolytic gasification once more, improved the energy conversion efficiency of gasification installation.
(2) hot water that condenses in the clarifier directly turns back in the burner hearth as one of gasifying agent by the tar recovery tube, one is to have improved the content of hydrogen in the combustible gas, another is that water by condensation in the gasification is as gasifying agent, realize the automatic supply of steam, and need not additionally add water again.
(3) whole gas generation process, simple and convenient, the material selectivity is big, consumption is little, gas production is high, and energy-saving effect is remarkable, and in-furnace dust, slag, gas can be realized effective separation, manually slag tap and lack blanking time, the combustion gas hygiene, the calorific value height, user or dealer need not pass through strict training simultaneously, only need to carry out simple operations, can realize normal use by product description.
