Embodiment Construction

[0048] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0049] like Figure 1-7As shown, the tower-type two-stage linkage fermentation system for promoting uniform distribution of bacteria includes a primary fermentation system 10 and a secondary fermentation system 40. A support 60 is provided at the bottom of the secondary fermentation system 40, so that the secondary fermentation system 40 is located The position is higher than the primary fermentation system 10. The basic principle is that when biogas is produced...

Abstract

The invention discloses a method for producing methane by using a system used for promoting uniform distribution of strains in a tower-type two-stage linkage fermentation way. The method comprises following steps: fermentation is performed in a first-stage fermentation system to generate methane and the generated methane is accumulated in a fermentation region formed between the side wall of a charge/discharge barrel and an adjacent gas blocking plate or between adjacent gas blocking plates; then, biogas slurry in a first-stage fermentation pipeline is pressed to flow into a first water guide pipe and a second water guide pipe and finally flow into a second-stage fermentation pipeline; methane is produced through fermentation in a second-stage fermentation system, is accumulated in a fermentation region formed between the side wall of a second-stage charge/discharge tube and an adjacent gas blocking plate or between adjacent gas blocking plates and finally flows into a hydraulic pressure room through the second-stage discharge pipe in a unidirectional way.

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...
