Efficient biogas generation system capable of improving turbulence effect of biogas slurry by virtue of biogas pressure

Abstract

The invention discloses an efficient biogas generation system capable of improving the turbulence effect of biogas slurry by virtue of biogas pressure. A U-shaped fermentation pipeline is horizontally arranged, a material inlet pipe and a material outlet pipe are vertically connected with both end sides of the U-shaped fermentation pipeline, a hydraulic pressure room is arranged at the upper part of the U-shaped fermentation pipeline, the connection position of the hydraulic pressure room and the material inlet pipe is a material inlet pipe drainage hole, the connection position of the hydraulic pressure room and the material outlet pipe is a material outlet pipe drainage hole, a material inlet pipe baffle plate is arranged at the connection position of the U-shaped fermentation pipeline and the material inlet pipe, a material outlet pipe baffle plate is arranged at the connection position of the U-shaped fermentation pipeline and the material outlet pipe and a biogas collection pipe is arranged on the U-shaped fermentation pipeline; the hydraulic pressure room is also connected with a bacteria-distribution device, one end side, departing from the material inlet pipe and the material outlet pipe, of the hydraulic pressure room is connected with a drainage pipe of the bacteria-distribution device, the other end of the drainage pipe is connected with a U-shaped bacteria-distribution pipe which is fixed inside the fermentation pipeline, the U-shaped bacteria-distribution pipe corresponds to the fermentation pipeline in shape and extends into the fermentation pipeline and a plurality of vertically upwards bacteria-distribution holes are formed in the U-shaped bacteria-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...

AI Technical Summary

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
