Abstract
The utility model relates to a methane pool, in particular to an uncovered high-heat-insulation methane pool built inside a greenhouse. The uncovered high-heat-insulation greenhouse methane pool comprises a cylindrical fermentation pool buried under the ground, wherein a methane pipe introduced into a hollow cavity arranged inside the pool is also arranged on the pool top of the fermentation pool, two side surfaces of the fermentation pool are respectively provided with a material inlet and a material outlet, and the material inlet and the material outlet are respectively communicated with a material inlet pool and a material outlet pool through pipelines. The uncovered high-heat-insulation greenhouse methane pool is characterized in that the top of the fermentation pool is not provided with a sealing cover, and a cover plate is arranged at the material inlet part. The methane pool is not provided with a cover, so the influence caused by external oxygen during cover uncovering does not exist, and the methane pool is always under a good anaerobic condition. Simultaneously, the temperature required by the fermentation is ensured because of greenhouse effect inside the greenhouse. The purposes of products of the methane pool are wide, the greenhouse temperature can be raised through produced gas, energy sources are saved, carbon dioxide and ammonia gas in the produced gas can be used as gas fertilizers, the plant metabolism is promoted, and the plant growth is favorably realized. Methane liquid and methane slag can be used as high-quality organic fertilizers of vegetables.
Description
Technical field
The present invention relates to a kind of methane-generating pit, especially build the high thermal insulation methane pool of uncovered of booth inside in.
Background technology
At present, the vast rural area of China generally builds a methane generating pit, with illumination and the fuel problem that solves vast rural area.In recent years, the methane-generating pit engineering development is very fast, but still exists removable cover than unmanageable and the low problem of gas producing efficiency in winter all the time.If the removable cover of methane-generating pit starts frequent, not only damage easily, and the material of taking off in the frequent fermentation vat of Gai Shihui contacts with oxygen, is unfavorable for biological anaerobically fermenting, thereby influences aerogenesis.In addition, particularly at the no clay in sandy soil area, very difficult gag.Thereby the removable cover at methane-generating pit top is difficult for maintenance and management.Simultaneously, winter temperature is lower, is difficult to maintain the required temperature of biological fermentation, and gas production rate is than obviously reducing summer, not even aerogenesis.
The various ways that heat are arranged at present, cross as some data introductions and utilize cattle and sheep excrement or faggot that methane-generating pit is carried out the technology of Winter protection, add thermal insulation layer on the ground, but thermal insulation layer is destroyed easily.Therefore, can't be incubated methane-generating pit owing to the topology layout restriction also is to cause one of methane-generating pit pond in winter temperature reason on the low side.
The utility model content
The objective of the invention is to overcome the problem that exists in the above-mentioned background technology, a kind of high thermal insulation methane pool of uncovered of building booth inside in is provided.Thereby inner the formation with biogas of booth is the optimum ecological circulation of tie, so both can solve the low problem of aerogenesis in winter, can reach the purpose of vegetables volume increase again.
The utility model proposes following technical scheme:
The high heat preservation greenhouse methane-generating pit of a kind of uncovered, comprise and be embedded in underground tubular fermentation vat, also be provided with the biogas pipe of a feeding pond internal cavity on the Chi Ding of described fermentation vat, the two sides of fermentation vat are shaped on opening for feed and discharge port respectively, and opening for feed and discharge port are communicated with charging pond and material-output tank by pipeline respectively; It is characterized in that: described fermentation vat top is not provided with capping, and the opening for feed place is provided with cover plate.
As preferably, described charging pond is up-small and down-big flared structure.Opening for feed is designed to tubaeform need and adds a cover, and diameter is big slightly, is convenient to artificial turnover operation.Methane-generating pit not only had been convenient to operate but also can have good anaerobically fermenting condition like this.
As preferably, be evenly equipped with fixed orifices on the described cover plate outer circumference surface.
Principle of work of the present invention is: the high heat preservation greenhouse methane-generating pit of this uncovered has solved the deficiency of removable cover, with top design is that uncovered and opening for feed are designed to big slightly tubaeform of diameter, both be convenient to manual maintenance, avoided again frequently taking off when covering and the contacting of air, thereby anaerobic condition preferably is provided, has helped the carrying out of fermentation activity.Simultaneously, by sunlight direct projection plastic greenhouse, booth has certain heat-insulating property, passes to the certain heat of methane-generating pit, and the temperature of fermentation is provided.The gas heating value of output is higher, and the booth internal temperature is risen, and prevents the freeze injury of vegetables, finally at one " Greenhouse effect " of the inner formation of booth.This effect has been guaranteed the state that is in comparatively high temps that methane-generating pit and booth continue, and has guaranteed the normal operation of fermentation gas, thereby realizes that methane-generating pit is high-efficiency insulated, reaches the high purpose of producing of vegetables.
The beneficial effects of the utility model are: because the methane-generating pit uncovered, do not taken off the influence of external world's oxygen when cover, be in all the time preferably under the anaerobic condition; Simultaneously because " Greenhouse effect " of booth inside have ensured the required temperature of fermenting.Under these two kinds of conditions, methane-generating pit can be realized high insulation high yield gas.In addition, the product of methane-generating pit is of many uses, and the gas of output can improve greenhouse temperature, save energy; Carbonic acid gas wherein and ammonia can be used as gas fertilizer, promote plant metabolism, help the growth of plant.Liquid natural pond, natural pond slag then can be used as the high-quality organic fertilizer of vegetables.Therefore the present invention not only is confined to biogas and is used to heat up water, cook, and the gas of output can also have the meaning of good penetration and promotion as gas fertilizer.
