Embodiment Construction

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] Such as Figure 1-3 As shown, the U-shaped biogas fermentation system includes a U-shaped fermentation pipeline 20, a feed pipe 11, and a discharge pipe 12. The feed pipe 11 and the discharge pipe 12 are arranged at both ends of the U-shaped fermentation pipeline 20 and placed adjacently The water pressure room 30 is placed on the upper part of the U-shaped fermentation pipeline 20, the connection position between the water pressure room 30 and the feed p...

Abstract

The invention discloses a U-shaped biogas fermentation system, 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 both ends of the U-shaped fermentation pipe. , the upper part of the U-shaped fermentation pipeline is placed with a water pressure room. A feed pipe air baffle is set at the connection position of the pipe, and a discharge pipe air baffle is set at the connection position between the U-shaped fermentation pipe and the discharge pipe; There is a one-way valve to control the one-way flow of the biogas slurry in the fermentation pipeline into the water pressure room; the U-shaped channel fermentation device is adopted, the fermentation route is long, and the biogas slurry can fully flow in the system by using the control of the water pressure difference and the one-way valve , and drive the uniform distribution of bacteria, effectively prevent 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...
