Abstract

The invention discloses a large capacity storage methane fermentation system which comprises a primary fermentation system and a secondary fermentation system, wherein the mounting position of the secondary fermentation system is higher than that of the primary fermentation system; the primary fermentation system and the secondary fermentation system are connected by virtue of a water guide pipe; the water guide pipe is connected between a secondary feeding pipe and / or discharging pipe and a primary fermentation pipeline; and a water guide pipe is connected between a water pressure room and the primary fermentation pipeline. An annular fermentation pipeline is adopted in the primary fermentation system, the fermentation route is long, circular flow of biogas slurry in the system is promoted by virtue of simultaneous fermentation of the primary fermentation system and the secondary fermentation system, stirring of the biogas slurry is effectively promoted, uniform culture distribution is promoted, and the fermentation efficiency in the system is improved.

Description

technical field

[0001] The invention relates to a biogas fermentation system, in particular to a multistage biogas fermentation system. Background technique

[0002] Biogas, the chemical name; methane, as the name implies, is the gas in the swamp; with the development of biogas science and technology in China and the promotion of household biogas in rural areas, according to local use requirements and conditions such as temperature and geology, household biogas pits have fixed arch cover water pressure Type pool, large uncovered hydraulic pool, hanging pipe hydraulic pool, meandering cloth hydraulic pool, top return hydraulic pool, separated floating cover pool, semi-plastic pool, all-plastic pool and tank pool. Although there are various forms, they are generally formed by four basic types of changes: hydraulic biogas digesters, floating cover biogas digesters, semi-plastic biogas digesters and tank-type biogas digesters.

[0003] The existing biogas still has many proble...
