Description

The simple and easy methane-generating pit of rural area family expenses

Technical field

The utility model relates to methane-generating pit, particularly the rural area household methane tank.

Background technology

Methane-generating pit is meant that each biolobic material carries out the closed unit that anaerobically fermenting is manually produced biogas by the microbial biochemical effect.Titles such as biogas generator, biogas fermentation device, anaerobic digestor are arranged again.Methane-generating pit is various informative, and structure differs, and can be divided into some types, divides by the air storage mode, can be divided into: hydraulic type biomass pool, cover-floating type methane-generating pit, air-bag type methane-generating pit.The cover-floating type methane-generating pit can be divided into again: top cover-floating type methane-generating pit with separate two kinds in cover-floating type methane-generating pit.The cover-floating type methane-generating pit is meant the methane-generating pit that biogas is stored by floating cover, and during generation, floating cover rises, and floating cover descends during with gas, and the cover internal gas pressure is comparatively stable.Floating being covered with of top cover-floating type methane-generating pit places fermentation vat top, the present top cover-floating type methane-generating pit of promoting, it is made up of feed-pipe, sweathouse, discharge room, airway, floating cover, cover plate etc., and sweathouse is garden, little, shallow pond type, floating cover is the floating cover of rigid cylinder, its manufacturing technology requires high, difficult sealing, and it is difficult to make, Production Time is long, recruitment is many, drops into thousands of units, and peasant household is beyond affordability.At present,, still there is the technical requirements height, problem such as it is difficult to make, and Production Time is long, and recruitment is many, drops into thousands of units, and peasant household is beyond affordability at the garden that China's rural area household methane tank is mainly promoted the use of, little, shallow hydraulic type biomass pool.In sum, no matter hydraulic type biomass pool or cover-floating type methane-generating pit, difficult peasant household is all beyond affordability, and its major cause has: the one, and the complex structure of methane-generating pit is difficult to make; The 2nd, the technical requirements height, construction is difficult, needs the professional and technical personnel to construct; The 3rd, investment is big, promptly drops into thousands of units, and peasant household is difficult to bear; The 4th, the construction period is long, and recruitment is many, and peasant household also is difficult to accept.Because the existence of these problems, it is very difficult to cause the rural area to popularize methane-generating pit, therefore, remain to be explored and the invention less investment, build fast, make easily, the simple and easy methane-generating pit of peasant household's acceptant rural area family expenses.

Summary of the invention

The purpose of the invention: provide a kind of rural area family expenses simple and easy methane-generating pit.

The utility model is achieved in that family expenses simple and easy methane-generating pit in rural area is to improve to form on cover-floating type biomass pool structure basis, existing top, it has feed-pipe, sweathouse, discharge room, airway, floating cover, sweathouse is the rectangle pond, long is 2000-2500mm, wide is 1000-1500mm, and height is 1700-2200mm; Floating cover is the floating cover of flexible pouch, it is made by plastics film, above the floating cover of flexible pouch airway is arranged, and below the floating cover of flexible pouch a rectangle counterweight ring made from bamboo wood or timber is arranged, rectangle counterweight ring is fixed on the fermentation partition, and the floating cover of flexible pouch directly places feed liquid; On the floating cover of flexible pouch, a load frame made from timber or bamboo wood is arranged; Sweathouse is connected by a liquid discharge pipe and a scum pipe with discharge room; Be connected with a pressure-regulator on the airway; On the load frame, briquetting is arranged; Load frame bolt is on collision bumper; On the methane-generating pit top, cover plate is arranged.The plastic film material of the floating cover of flexible pouch is a polyethylene, and thickness is 0.14-0.50mm, and the number of plies is the 1-2 layer.Liquid discharge pipe is 25-50mm steel pipe and hose connection the forming of a joint by a joint diameter, and steel pipe is embedded in the partition wall of sweathouse and discharge room, 600-1200mm place at the bottom of the sweathouse pond; Scum pipe is 50-100mm steel pipe and hose connection the forming of a joint by a joint diameter, and steel pipe tilts to be embedded in the partition wall of sweathouse and discharge room 100-150mm place at the bottom of the sweathouse pond.The shell of pressure-regulator is transparent plastic containers, and graduated scale is arranged outside container, in a transparent inlet pipe moving up and down is arranged, a venting port is arranged above plastic containers.

Methane-generating pit of the present utility model, structure is very simple, it is very easy to make, general 4-5 worker promptly can be made into, only be 1/4 of isometric cover-floating type methane-generating pit recruitment, cost of manufacture about 400 yuan, only is 1/3 of an isometric cover-floating type produced by methane-generating pit cost only, its aerogenesis effect is suitable, is easily accepted by peasant household.
