Hydraulic double-pipe channel type biogas generator

Abstract

The invention discloses a hydraulic double-pipe channel type biogas generating device, which includes a feed pipe, a discharge pipe, and a U-shaped fermentation pipe. The U-shaped fermentation pipe is placed horizontally, and the feed pipe and the discharge pipe are vertically connected to the U-shaped fermentation pipe. At both ends of the pipeline, a water pressure room is placed on the upper part of the U-shaped fermentation pipeline. A feed pipe air baffle is set at the connection position between the pipeline and the feed pipe, and a discharge pipe air baffle is set at the connection position between the U-shaped fermentation pipeline and the discharge pipe; The position of the drainage hole is provided with a one-way valve to control the one-way flow of the biogas slurry in the fermentation pipeline into the water pressure room, and the one-way valve is set on the drain hole of the feed pipe to control the one-way flow of the biogas slurry in the water pressure room into the feed pipe; The channel-type fermentation device has a long fermentation route, and uses the control of water pressure difference and one-way valve to realize the full flow of biogas slurry in the system, and to drive the uniform distribution of bacteria, effectively preventing crusting, high gas production rate, suitable for Large-scale production.

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...
