Biogas generation method for assembly-type U-shaped biogas-slurry-turbulence biogas generation system

Abstract

The invention discloses a biogas generation method for an assembly-type U-shaped biogas-slurry-turbulence biogas generation system. The method comprises steps as follows: a fermentation raw material is poured into a U-shaped fermentation pipeline through a feeding pipe and is fermented in the U-shaped fermentation pipeline to produce biogas, the biogas is accumulated in a space between the side wall of the feeding pipe and the side wall of the discharging pipe, and the biogas occupies the space in the fermentation pipeline and squeezes biogas slurry in the fermentation pipeline to flow to the feeding pipe and the discharging pipe and then flow into a hydraulic pressure chamber through a discharging pipe water-discharging pipe in one direction. The biogas stored in the fermentation pipeline is used, and the pressure of the biogas in the fermentation pipeline is reduced, so that the biogas stored in the hydraulic pressure chamber flows back to the fermentation pipeline through a feeding pipe water-discharging pipe in one direction, and circulatory flowing of the biogas slurry is completed; biogas is constantly produced and used with methods A and B, and the circulatory flowing of the biogas slurry is promoted.

Description

technical field [0001] The invention relates to an anaerobic fermentation device, in particular to a methane fermentation system. Background technique [0002] The working principle of the traditional biogas digester is that when biogas is generated in the pond, the biogas in the gas storage room increases continuously, and the pressure continues to increase, forcing the liquid level in the main pool to drop, and a part of the material liquid is squeezed out into the hydraulic room. When people turn on the stove, the pressure in the biogas digester gradually drops, and the feed liquid in the hydraulic chamber continuously flows back to the main pond. In this way, gas is produced and used continuously, so that the pressure in the fermentation room and the discharge room is always maintained in a state of pressure balance. [0003] Traditional biogas digesters have short fermentation routes, poor fluidity of biogas slurry, and uneven distribution of bacteria, resulting in a de...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the deficiencies of the prior art, the technical problem to be solved by the present invention is that the fermentation efficiency route of the traditional biogas digester is short, the fermentation efficiency is low, and the biogas slurry convection effect is poor, resulting in uneven distribution of bacteria, etc.
