Description

Stove formula Household dry fermentation methane producer

Technical field

The utility model relates to a kind of biogas generator, particularly relates to a kind of stove formula Household dry fermentation methane producer.

Background technology

Biogas is a kind of inflammable gas that Wood Adhesives from Biomass is the energy that utilizes, in China, be widely applied already, and can produce the marsh gas fermentation pool of biogas or the stationary structure that the mixed earth of fermentor tank modal most employing masonry in rural area is built into, simple and practical, but defect is more, once can not move after building up, and changed greatly by territorial environment and weather condition, the methane-generating pit of the cold mixed clay structure in the north cannot be used, factor of created gase is low, use inconvenience etc., someone utility model adopt steel make portable fermentation vat, and employing insulation, heating unit improves fermenting speed and solves the problem of north use in winter, though the cold place of this device all can be used, and factor of created gase is higher, but exist complex structure, bulky, it is large that heating unit consumes the energy, without electric rural area, mountain area, nomad area can not be used.Aerogenesis raw material is commonly used changing food waste, feces of livestock and poultry, and after fermentation, slag liquid discharge has pollution need administer etc., therefore no matter equipment cost or use cost are all higher, cannot promote the use of in rural area, mountain area and nomadic regional peasant household; The 2nd, the raw material that its aerogenesis of current biogas generating device is used is all changing food waste, just the like waste of pig cow dung, is all in order to solve environmental pollution, adopts wet type fermentation mode, and the slag liquid after aerogenesis still exists environmental pollution to be administered, and has improved aerogenesis cost.For vast rural area, how to use in a large number stalk, take the economical and practical type biogas generator of dry type fermentation mode aerogenesis at present without this equipment, suddenly treat that people go research and development.

Summary of the invention

The purpose of this utility model is that a kind of stove formula Household dry fermentation methane producer that is applicable to vast rural area, mountain area, the use of nomad area will be provided.

The utility model is achieved in that a kind of stove formula Household dry fermentation methane producer, comprise housing, stove formula heating unit, its middle shell is a kind of double-deck sealing member, centre is manufactured with thermal insulation layer by foaming mode, tensimeter, pneumatic tube, opening for feed, discharge port and thermometer are housed on housing, the reinforced lid of bayonet type is equipped with by sealing-ring in upper edge at opening for feed, safety valve is equipped with in central position in reinforced lid, in the outer of discharge port, by sealing-ring, bayonet type discharging lid is housed, stove formula heating unit comprises roasting kiln, stack cover, stove pad, ash output hole, ash discharge lid and biogas burner, wherein roasting kiln is arranged on the central position in housing, the housing top that is contained in suitable for reading of roasting kiln, not only make the charging opening of fuel but also make chimney, stack cover is contained in upper (being on throat) suitable for reading of roasting kiln, stove pad is contained in the top, bottom of roasting kiln, below stove pad, through housing, ash output hole is housed, ash discharge lid is housed on ash output hole, biogas burner is contained in the bottom oven pad top of roasting kiln, feet is equipped with in bottom at housing, for ease of movement, bottom at feet also can fill shifting roller.

The stove formula Household dry fermentation methane producer designing and producing according to technique scheme, compared with prior art its outstanding advantage is:

1, stove formula Household dry fermentation methane producer of the present utility model has been filled up a blank in domestic biogas generator.Because existing biogas generator is all external indirect-heating electrically heated, wet fermentation, and the utility model employing direet-heating type is directly to heat by roasting kiln body of heater, heat to be conducted to the stalk powder as fermentation material, and dry fermentation, therefore thermo-efficiency is high.

2, mixing can be by homemade marsh gas power generation after biogas generator, solves the families such as mountain area, nomad without electric inconvenience.

3, the utility model adopts stalk powder to make biogas; both solved the source of aerogenesis raw material; the a large amount of stalks in rural area have been processed again; avoid burning environmental pollution; and slag charge after fermentation gas is capable of using as feed, fertilizer, fuel are used; compared with wet fermentation, the slag charge after aerogenesis is pollution-free, is conducive to environment protection.

4, charging lid, discharging lid adopt bayonet type structure, and good seal performance is simple, convenient.

5, roasting kiln is a two-purpose stove, and its fuel both can have been used timber, coal, also can directly use homemade biogas.

6, stove formula Household dry fermentation methane generator architecture is simple, raw material sources are wide, cost of manufacture is low, economic operating cost, factor of created gase are high, without power supply support, is specially adapted to rural area, mountain area, nomad family and uses.

7, the utility model adopts direet-heating type, dry fermentation, but equipment itself also can be used for wet fermentation.
