Method for producing biogas in water-pressure type horseshoe-shaped efficient biogas tank with biogas slurry circulative convection

Abstract

The invention discloses a method for producing biogas in a water-pressure type horseshoe-shaped efficient biogas tank with biogas slurry circulative convection. The method comprises the following steps: pouring fermentation raw materials into a U-shaped fermentation pipeline through a discharge tube and fermenting in the U-shaped fermentation pipeline to produce biogas; and gathering the biogas to a fermentation region which is formed between the side wall of a charge / discharge tube and an adjacent gas baffle plate or adjacent gas baffle plates, introducing the biogas into a space in the fermentation region and extruding the biogas slurry in the fermentation region to form convection, so as to enable the biogas slurry exhausted out of the fermentation pipeline to flow to the charge tube, the discharge tube and a bacteria distributing device, and flow into a water pressure room through a water outlet tube of the discharge tube.

Description

technical field [0001] The invention relates to an anaerobic fermentation device, in particular to a biogas 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 dec...

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.
