Abstract

The invention discloses a method for generating biogas by a hydraulic double-pipe channel type biogas generating device. The steps include: pouring fermentation materials into a U-shaped fermentation pipeline through a feed pipe and fermenting to generate biogas, and the biogas is accumulated in the U-shaped fermentation pipeline. In the space between the feed pipe air baffle and the discharge pipe air baffle, biogas occupies the space in the fermentation pipe and squeezes the biogas slurry in the fermentation pipe to flow into the feed pipe and discharge pipe, and drain through the discharge pipe The hole flows into the water pressure room in one direction; when the biogas stored in the fermentation pipeline is output to the outside through the gas collecting pipe, the pressure of the biogas in the fermentation pipeline drops, and the biogas slurry stored in the water pressure room flows back into the fermentation pipeline through the drainage hole of the feed pipe , to complete the circulation of biogas slurry.

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...
