Horseshoe multi-area mixing flow stirring type super-efficient marsh gas generation system

Abstract

The invention discloses a horseshoe multi-area mixing flow stirring type super-efficient marsh gas generation system which comprises a feed pipe, a discharge pipe, a U-shaped fermentation pipeline and a hydraulic pressure room, wherein the feed pipe and the discharge pipe are detachably inserted into the two end sides of the U-shaped fermentation pipeline; the side wall of the feed pipe and the side wall of the discharge pipe stretch into the U-shaped fermentation pipeline; the hydraulic pressure room is placed at the top of the U-shaped fermentation pipeline; a horizontally-placed feed pipe drain pipe is connected between the hydraulic pressure room and the feed pipe; a horizontally-placed discharge pipe drain pipe is connected between the hydraulic pressure room and the discharge pipe; a gas guide pipe is arranged on the U-shaped fermentation pipeline; the marsh gas generation system is long in fermentation route and remarkable in biogas slurry flowing and stirring effect and effectively promotes uniform distribution of strains.

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.
