Abstract

The inventive gasification stove has a stove body, in which the upper section cavity is a fuel bunker with a gas inlet pipe inside. At the end of the gas inlet pipe is welded a nozzle and on one side of the stove body in the sane height as the nozzle is opened an ignition hole. The middle section in the stove body is a gasification chamber, whose diameter is smaller than one of the fuel bunker. At the bottom of the gasification chamber is disposed a supporting bar mounted a grid and an ash remover, and the bottom of the grid is connected with an ash chamber. On one side of the stove body near the above of the gasification chamber is opened a combustible gas outlet connected with a cleaner, whose end is plugged in the water tank. On top of the stove body is disposed a stove lid assembly.

Description

Domestic efficient biomass gasification stove
Technical field
The present invention relates to solid fuel ignition equipment, relate in particular to a kind of domestic efficient biomass gasification stove.
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 object of the present invention is to provide that cost is low, efficient is high, handling safety, a kind of domestic efficient biomass gasification stove that applicability is strong, the agricultural abandoned biomass is changed into high-grade fuel gas.
The technical solution used in the present invention 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 present invention compares 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.
Description of drawings
Fig. 1 is the structural representation of biomass gasifying furnace;
Fig. 2 is the structural representation of grate.
Among the figure: 1, air inlet switch, 2, air inlet pipe, 3, Bunker, 4, fire hole, 5, vaporizer, 6, grate, 7, fire door, 8, body of heater, 9, support bar, 10, ash-cleaning device, 11, clarifier, 12, fuel gas outlet, 13, nozzle, 14, the bell assembly, 15, explosion-proof spring.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
As shown in Figure 1, the present invention is made up of body of heater 8, bell assembly 14, vaporizer 5, Bunker 3, grate 6, ash-cleaning device 10, clarifier 11 etc.Body of heater 8 is a cylinder; epimere cavity in the body of heater 8 is a Bunker 3; be provided with an air inlet pipe 2 in the Bunker 3; the outside of air inlet pipe 2 links to each other with blower fan by check valve or air inlet switch 1; when blower fan is shut down; in time close air inlet switch 1 or close automatically because of check valve 1, can prevent furnace gas because of hypertonia from air inlet pipe 2 oppositely ejection hurt sb.'s feelings.Air inlet pipe 2 ends are welded with stainless steel nozzle 13, and having three row's diameters on the nozzle 13 is the spray wind hole of 2~3mm.The air that blower fan blasts can obtain abundant preheating in Bunker 3, combustion-supporting from nozzle 13 ejections, greatly improves the thermal efficiency of gasification furnace.Have a fire hole 4 with body of heater 8 one sides at the concordant place of nozzle 13 height and positions, when stove starts from then on the hole introduce the flare material that ignites.Stage casing cavity in the body of heater 8 is provided with vaporizer 5, and intraformational bed is filled heat insulating pearlite material, plays the heat-insulation and heat-preservation effect.Vaporizer 5 diameters are less than Bunker 3 diameters, the larynx neck that has a diameter to dwindle in the middle of the vaporizer 5, vaporizer 5 bottoms are welded with four uniform support bars 9, grate 6 and ash-cleaning device 10 are housed on the support bar 9, grate 6 is welded (as shown in Figure 2) by the staggered steel bar of two rows, ash-cleaning device 10 passes cinder chamber and links to each other with the handle of outside, when lime-ash can not drop and when blocking naturally, can shake the outer handle of body of heater 8.Hypomere cavity in the body of heater 8 is cinder chamber and ash hole, and ash hole is sealed by fire door 7 during burning.Body of heater 8 one sides near the vaporizer top have fuel gas outlet 12, link to each other with clarifier 11 by pipeline, clarifier 11 is a cyclone separator, the cylinder end straight cutting of cyclone separator is gone in the explosion-proof water tank, fuel gas forms eddy current in cyclone separator, isolate tar and dust.The top of body of heater 8 is a bell assembly 14, and bell 14 is provided with the band charge door of sealing device and a prescription to opposite explosion-proof spring 15, can overcome spring pressure and pressure release when furnace pressure is too high.
