Description

A kind of firewood ＆ stalks gasification stove
Technical field：
The invention belongs to a kind of faggot straw gasifying stove, specifically the organic matters such as faggot, stalk are converted into stove The gas-cooker burning specially made is sent to after imflammable gas.
Background technology：
At present, coal gas or gas fuel have all been used in many cities, and this not only makes urban air environment be greatly improved, and And brought great convenience to life, as long as resident opens gas stove switch one, you can dish of cooking of heating up water, it is not only simple and convenient but also clear Clean health, but in vast rural area, it is sparsely populated, it is unlikely that gas piping or natural gas line are all led into every family, most Good method is to gather materials on the spot, and the various discarded gasifiable feedstocks of farmers' are converted into imflammable gas, this gasifiable original Material includes faggot, sawmilling, husk, wood shavings, corncob, beans bar, cotton stalk, sesame straw, wheat straw, peanut shell, tree deciduous leaf, food bacterium Discarded object ox, sheep, horse argol etc., these discarded objects per peasant household collect at least every year it is several very heavy, if gasified Caused imflammable gas, it can be needed completely for every peasant household's whole year combustion gas, the gasifiable feedstock for these farmers' are discarded is converted into Imflammable gas, many people think hard designing various gasification furnaces, such as patent of invention《Automatic ignition type stalk gasifier》, application Numbers 200620051195.3；《A kind of biomass gas stalk gasifying stove》, application number 200620051365.8, these gasification furnaces are all It using stalk, rice husk, faggot, wood chip etc. is raw material to be, under anaerobic conditions, imperfect combustion, organic matter is resolved into rapidly The imflammable gas such as carbon monoxide, methane, ethane, used after purified for gas-cooker.In the prior art, or structure is simple It is single, but some problems have been used, or complicated, cost is high.
The content of the invention：
The purpose of the present invention, it is to invent a kind of a kind of low but easy to use firewood ＆ stalks gasification stove of cost simple in construction, Allowing vast countryside and peasantry to afford to use use must get well.
The principle of the present invention, is to make combustable organic thing imperfect combustion in stove in the case of oxygen deprivation high temperature, resolves into The materials such as carbon monoxide, methane, ethane, carbon, steam, carbon dioxide, tar, steam are returned in stove through arch form bell (7) condensation, Reduction reaction is produced with red-hot carbon and generates flammable carbon monoxide and hydrogen, and red-hot carbon and carbon dioxide generation reduction are anti- Flammable carbon monoxide should be generated, tar returns in stove the decomposition that burns away through the condensation of arch bell 7, and it is unnecessary that bell 7 condenses Water flow to body of heater inner bag along circular arch and absorbed by inner bag, so the gas master come out in a kind of firewood ＆ stalks gasification stove gas outlet 14 If imflammable gas such as carbon monoxide, hydrogen, methane, there are a small amount of tar and steam to condense filtering i.e. by filter 15 and 16 It can remove.
A kind of firewood ＆ stalks gasification stove of the present invention is it was found from Figure of description, including base 1, the stove on base 1 Body case 2, body of heater inner bag 3, furnace bottom grate 4, the blower fan 5 outside stove, the filter of the bell 6 on furnace roof and gas outlet 7th, 8, it is characterised in that stove first 9 is equipped with burner hearth interior base 1, there is many arch side of stove first 9 in body of heater inner bag Stomata, but top is upper non-porous, and stove first 9 has oxygenation port 10, and there is ash hole 11 in stove rostral face, between shell 2 and body of heater inner bag 3 It is that heat-insulation layer 13, lower portion of furnace body have ash hole 14 by the position of grate 4, lower portion of furnace body has gas-adding pipe 15, top to have escape pipe 16, There are disk 17 on closure, the hollow diameters of upper disk 17 to be slightly less than the diameter of body of heater inner bag 3 between bell 6 and body of heater, in each pipeline Inlet and outlet has Valve controlling air inlet and outlet.
Body of heater inner bag 3 is to add 2 to form by refractory cement and seat clay, and when moisture content is excessive in stove, material has hygroscopicity, Fire leaching in stove will not be put out at once, while be not easy to conduct heat, the temperature in favourable holding furnace body.
Body of heater height and body of heater internal diameter will have certain proportion, tests prove that stove height burns with the ratio between warp in body of heater for 1.5: 1 Gasification result is best.
Bell 6 is processed into arch, is advantageous to the condensation of steam and tar, reduces the water exported from escape pipe 16 in combustion gas Vapour and tar content, make combustion gas purer, reduce environmental pollution, filtration device structure is become more simple, only use air setting Filtering.
In order to strengthen the heat insulation effect of body of heater, in addition to having heat-insulation layer between body of heater shell and body of heater inner bag, furnace bottom also has Heat-insulation layer 18.
Bell 6 is processed into arch, as pot cover, is advantageous to the condensation of steam and tar.
The present invention has following features：
1. not having to light a fire again when using daily after once lighting a fire successfully, because furnace insulation performance is good, ash content wraps up during blowing out Mars, when blower fan is blown, can revive again.
2. gasification result is good, per kilogram stalk can produce 2m3 combustion gas.
3. the body of heater internal layer 3 of heat-insulation layer 13 is all nonmetallic materials, through cost accounting, the hundreds of members of this gasification furnace cost, and peasant Afford to use.
4. aboundresources, the applicable raw material range of this gasification furnace is broad, including faggot, sawdust, husk, wood shavings, corncob, Beans stalk, cotton stalk, sesame stalk, wheat straw, straw, branch, fallen leaves, waste edible fungus gurry, ox, sheep, the argol etc. of horse, peasant household is annual At least thousands of jin, enough each peasant household's whole year combustion gas use.
5. save the energy, environment purification.After gasification furnace, burning coal can be completely dispensed with, has both saved purchase coal money, simultaneously Purified environment, using gasification furnace user only need to toward the built-in 6-8 jin faggot of burner hearth can do five mouthfuls of people food of one day and Domestic water, the limitation of climate condition, does not compare with traditional coal stove, saves the energy, economy, calculates.Such as burn a kettle 6kg boiling water 6-8 minutes are only needed, boiling one pot of 25Kg of heat pig feed only needs 45~50 minutes, it is most important that it changes rural kitchen completely The situation of " smoke fire bakes people ", make peasant household from traditional cooking stove fall behind cook in liberated oneself.
