Background technology
Scarcity of resources, ecological deterioration are the major crisis of face of mankind nowadays, and various pollutions are serious day by day to the infringement of earth environment, and the mankind have only the dependence of breaking away from as early as possible fossil fuel, and the rational exploitation and utilization regenerative resource could purify oneself living environment.
Biomass energy is a kind of regenerative resource, according to estimates, have approximately about 700,000,000 tons every year such as utilizable biomass resource in China rural area such as agricultural crop straw, forest tree castoff, edible fungi residues, but its utilization rate is very low, and because of improper disposal (as burning) contaminated environment.At present, it is fuel with biological material still that China still has the family about 2.3 hundred million, but the uncleanly direct burning of original stalk poor efficiency utilizes the mode needs that improve of incompatibility life of farmers level, urgently wishes that low-grade biomass energy that energy density is low is converted into high-quality, cleaning, high-grade energy efficiently.Therefore, the utilization and extention biomass energy will produce immeasurable social benefit and economic benefit, and nervous with energy to alleviating the rural area, improving the ecological environment has great significance.
Summary of the invention
The purpose of this utility model is to provide that cost is low, efficient is high, handling safety, a kind of domestic efficient biomass gasification stove that applicability is strong, and the agricultural abandoned biomass is changed into high-grade fuel gas.
The technical solution adopted in the utility model is: the epimere cavity in the body of heater is a Bunker, be provided with an air inlet pipe in the Bunker, the air inlet pipe end is welded with nozzle, have a fire hole with body of heater one side of nozzle sustained height, stage casing cavity in the body of heater is a vaporizer, the vaporizer diameter is less than the Bunker diameter, the larynx neck that has a diameter to dwindle in the middle of the vaporizer, the vaporizer bottom is provided with four uniform support bars, grate and ash-cleaning device are housed on the support bar, ash accepting chamber, grate lower end, body of heater one side near the vaporizer top has the fuel gas outlet, the clarifier outer by pipeline and body of heater links to each other, and the cylinder end straight cutting of clarifier is gone in the water tank, and the top of body of heater is provided with the bell assembly.
Described grate is welded by the staggered steel bar of two rows.
Described bell assembly is provided with a prescription to opposite explosion-proof spring.
The outside of described air inlet pipe is to link to each other with blower fan by check valve or air inlet switch.
Described nozzle be have three row diameters be the nozzle in the spray wind hole of 2～3mm.
The utility model is compared the beneficial effect that has with background technology: adopt the method for body of heater top air inlet, the air that enters is fully preheating in Bunker, makes heat of gasification transformation efficiency height, and adaptability to raw material is strong; Bell is provided with a prescription to opposite spring, and the cylinder end straight cutting of cyclone separator goes in the water tank, when can pressure release during hypertonia in the stove or in the pipeline, guarantees stove and accessory and operating personnel's safety; Grate is provided with the hand-rail type ash-cleaning device, can overcome the lime-ash choking phenomenon.
