Method for generating biogas in intertwined partitioned super-efficient bacteria distribution biogas fermentation system

Abstract

The invention discloses a method for generating biogas in an intertwined partitioned super-efficient bacteria distribution biogas fermentation system. The method includes the steps: pouring fermentation raw materials from a feeding pipe and fermenting the raw materials in a fermentation pipeline to generate the biogas; using the biogas stored in an optional fermentation area. The biogas is respectively gathered in fermentation areas formed among the feeding/discharging pipe and adjacent gas baffle plates or between the adjacent gas baffle plates, occupies space in the fermentation areas, squeezes biogas slurry in convection and flows towards the feeding pipe and the discharging pipe, and the biogas slurry in the fermentation pipeline flows into a water pressure space through a drain hole of the discharging pipe along with rise of the liquid level of the biogas slurry in the feeding pipe and the discharging pipe. The pressure of the biogas stored in the optional fermentation area is reduced, the biogas slurry in an adjacent fermentation area flows towards the optional fermentation area, and the biogas slurry stored in the water pressure space unidirectionally flows into the fermentation pipeline through a drain hole of the feeding pipe and flows back into the fermentation pipeline through the drain hole of the discharging pipe to supplement reduced biogas space, so that circulating flow of the biogas slurry is finished.

Description

technical field [0001] The invention relates to the technical field of biogas, in particular to a biogas fermentation system. Background technique [0002] According to statistics, there are currently about 3 million biogas problems in my country. The problems are: 1. Unreasonable materials used, causing serious air and water leakage in the pool; 2. Poor mechanical performance of biogas digesters, reducing biogas The structural strength of the pool causes wide structural stress cracks inside the pool body; 3. The connection between the inlet / outlet pipe and the pool body is bent, sheared or even broken, and the shearing causes serious water and air leakage in the biogas tank; 4. 1. The fermentation route of the biogas digester is short, the efficiency of gas production is low, it is easy to crust, it is difficult to clean, and a large number of waste ponds are generated. Contents of the invention [0003] The technical problem to be solved by the invention is that the ferme...
