Abstract

The invention discloses a tower-type two-stage linkage fermentation system for promoting uniform distribution of strains, which includes a primary fermentation system and a secondary fermentation system, the installation position of the secondary fermentation system is higher than that of the primary fermentation system, the primary fermentation system and the secondary fermentation system The first-stage fermentation systems are connected by aqueducts, the secondary feed pipes and / or discharge pipes are connected with the first-stage fermentation pipes, and the water pressure rooms are connected with the first-stage fermentation pipes; the first-stage The fermentation system adopts a circular fermentation pipeline with a long fermentation route. The synchronous fermentation of the primary fermentation system and the secondary fermentation system promotes the circulation of the biogas slurry in the system, effectively promotes the stirring of the biogas slurry, and drives the uniform distribution of bacteria. Improve the fermentation efficiency in the system.

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...
