Super-efficient biogas generation system with function of promoting biogas liquid flowing and bacterial distribution under gas pressure

Abstract

The invention discloses a super-efficient biogas generation system with a function of promoting biogas liquid flowing and bacterial distribution under the gas pressure. The biogas generation system is characterized in that a feeding pipe and a discharging pipe are vertically connected to the two sides of a U-shaped fermentation pipeline; a water pressure chamber is formed in the upper part of the U-shaped fermentation pipeline; a feeding pipe water outlet is formed in the joint of the water pressure chamber and the feeding pipe; a discharging pipe water outlet is formed in the joint of the water pressure chamber and the discharging pipe; a feeding pipe gas baffle is arranged at the joint of the U-shaped fermentation pipeline and the feeding pipe; a discharging pipe gas baffle is arranged at the joint of the U-shaped fermentation pipeline and the discharging pipe; a gas collecting pipe is arranged on the U-shaped fermentation pipeline; the water pressure chamber is connected with a bacterial distribution device; a water discharge pipe of the bacterial distribution device is connected to one side, deviating from the feeding pipe and the discharging pipe, of the water pressure chamber; the other side of the water discharge pipe is connected and fixed to a U-shaped bacterial distribution pipe in the fermentation pipeline; the U-shaped bacterial distribution pipe is matched with the fermentation pipeline in shape and extends into the fermentation pipeline; a plurality of bacterial distribution holes are vertically formed in the U-shaped bacterial distribution pipe.

Description

technical field [0001] The invention relates to the technical field of biogas, in particular to a biogas fermentation system. Background technique [0002] China's biogas originated in the 1970s and has a development history of nearly 40 years. It has experienced three stages of ups and downs. From 1971 to 1981, it was a stage of rapid development and decline; from 1981 to 1991, it was a stage of adjustment and emphasis on technology; 1991 The period from 2000 to 2000 is the stage of recovery and the benefits are highlighted; the period from 2001 to 2009 is the stage of comprehensive improvement and rapid development; after 2009, it tends to fall back. [0003] Looking back at the ups and downs of biogas development in China, we have fully analyzed the existing problems of biogas (household use) in China: 1. The structure of the biogas fermentation part is unreasonable, and the current promotion is still the pool type fermentation system in the 1980s , It is difficult to fe...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the fermentation route in the biogas fermentation system is short, the biogas slurry self-circulation effect is poor, and the uneven distribution of bacteria in the biogas slurry affects the gas production rate
