Abstract

The utility model relates to a large biogas generating pool, and in particular relates to a large concrete biogas generating pool. The large concrete biogas generating pool comprises a feed room, a feed orifice, a digestion pool, a discharge port, a discharge room, a gas outlet and an agitating blade. The large concrete biogas generating pool is characterized in that the pool body is poured by concrete (in an underground form or partial underground form, preferably in the form of a tunnel), and the corner of the pool body is designed in a large arc shape; the feed room is arranged at one end and a large-caliber feed tube is pre-buried, and the discharge room is arranged at the other end; the digestion pool is communicated with the discharge room through the discharge port and a liquid outlet, the liquid outlet is arranged on the upper part of the discharge port, the pool bottom inclines downward in a slope manner from the feed room end to the discharge room end, and the top of the pool is poured to be arc-shaped or slope-shaped and a gas outlet tube is pre-buried; antiseep and antiseptic treatments are carried out on the pool body and the inner walls of the top of the pool by glass fiber reinforced plastic resin; the pool is internally provided with an agitating shaft and a fan blade, and antiseptic treatment is carried out on the metal material by spraying the glass fiber reinforced plastic resin, and the metal material is installed on the pool wall and connected with a low speed motor or a rocking arm outside the pool; and an insulating layer made of rock wool products is arranged outside the biogas generating pool. The large biogas generating pool is constructed by concrete materials, has the mechanical agitating function and can insulate heat in winter.

Description

The large-sized concrete methane-generating pit

Technical field

The utility model relates to a kind of large methane tank, is specifically related to a kind of concrete macrotype methane-generating pit.

Background technology

At present, what the large methane tank more than 300 cubic metres generally adopted is the Plate Welding moulding, enamel anticorrosion combines, the technology of building on the ground, this technology cost is high, and is difficult to effectively stir and Winter protection, only has the summer in 1 year, can normally move in two seasons of autumn, winter, spring can not normally use, and cause significant wastage.

Summary of the invention

The utility model is for the deficiencies in the prior art, the large methane tank that provides a kind of concrete material to build up to have the mechanical stirring function and be convenient to Winter protection.

The technical solution of the utility model is: a kind of large-sized concrete methane-generating pit, comprise digester, the charging mouth of pipe, discharge port, discharge room, air outlet and stirring flabellum, it is characterized in that: concrete placement pond body is (underground or partly lower, take tunnel like as best), pond body corner adopts large arc design, one end is provided with feed space, and pre-buried heavy caliber feed-pipe, the other end is provided with discharge room, digester is connected with discharge port and liquid outlet with discharge room, liquid outlet is on discharge port top, be sloping formula declivity by feed space one end to discharge room one end at the bottom of the pond, the pond top casting builds up arch or domatic, and pre-buried escape pipe, and pond body and top, pond inwall are brushed the glass reinforced plastic resin and carried out antiseep and rotproofing, be provided with stir shaft and flabellum in the pond, its metallic substance adopts glass reinforced plastic resin spraying coating process to carry out rotproofing, is installed on the outer slowspeed machine of pool wall and connection pool or rocking arm, adopts asbestos product to do thermal insulation layer outside the pond.

The beneficial effects of the utility model are: adopt concrete material to build, sturdy and durable, construction cost is low; Use the glass reinforced plastic resin to brush pool wall, anti-corrosion leak-proof is effective; Whipping appts is simple and practical, both can effectively stir feed liquid, increases gas production rate, can effectively abolish again the feed liquid crust, and machinery, hand mixing all can; The dead angle has been avoided in the large arc design of pond body corner, makes things convenient for discharging; Adopt sloping formula design at the bottom of the pond, can guarantee that discharging is thorough; Liquid outlet is convenient to extract natural pond liquid by discharge room; Methane-generating pit is built in underground or semi-underground, can adopt winter plastic greenhouse or stacking biological straw effectively to be incubated, and is convenient and easy; For the ultra-large type methane-generating pit, can adopt some monomers pond to combine.
