Super-efficient biogas generation system having plurality of horseshoe-shaped partitions and capable of increasing turbulence of biogas slurry

Abstract

The invention discloses a super-efficient biogas generation system having plurality of horseshoe-shaped partitions and capable of increasing the turbulence of biogas slurry. The super-efficient biogas generation system comprises a material inlet pipe, a material outlet pipe, a U-shaped fermentation pipeline and a hydraulic pressure room, wherein the material inlet pipe and the material outlet pipe are detachably inserted at both end sides of the U-shaped fermentation pipeline and the side walls of the material inlet pipe and the material outlet pipe extend inside the U-shaped fermentation pipeline, the hydraulic pressure room is arranged at the top of the U-shaped fermentation pipeline, a horizontally arranged material inlet pipe drainage pipe is connected between the hydraulic pressure room and the material inlet pipe, a horizontally arranged material outlet pipe drainage pipe is connected between the hydraulic pressure room and the material outlet pipe and a biogas guide pipe is arranged on the U-shaped fermentation pipeline; a one-way valve for controlling the biogas slurry inside the hydraulic pressure room to flow inside the material inlet pipe in a one-way manner is arranged on the material inlet pipe drainage pipe, and the horizontal plane at which the lowest position of the material outlet pipe drainage pipe is positioned is higher than that at which the lowest position of the material inlet pipe drainage pipe is positioned. The super-efficient biogas generation system has the advantages that the fermentation route is long, biogas slurry flowing and stirring effects are significant and uniform distribution of bacterial strains is effectively 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...

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.
