Method for producing biogas by employing device for improving biogas slurry turbulence effect of pipelined fermentation system

Abstract

The invention discloses a method for producing biogas by employing a device for improving a biogas slurry turbulence effect of a pipelined fermentation system. The method comprises the following steps: a fermentation raw material is poured into a fermentation system to be fermented to generate biogas, the biogas is gathered in fermentation areas formed between two adjacent air baffle plates, and pressure of the biogas in the fermentation areas is increased to push biogas slurry in a fermentation pipeline to flow towards the feeding pipe and the discharge pipe and to flow into a water pressure room through a feeding pipe drain pipe and a discharge pipe drain pipe; the biogas in any fermentation area is utilized, the pressure of the biogas in the fermentation area is reduced, and the biogas slurry stored in the water pressure room flows back to the fermentation pipeline through the feeding pipe drain pipe and the discharge pipe drain pipe to finish circular flowing of the biogas slurry; and the biogas in other fermentation areas is utilized, and the biogas is generated and utilized according to the steps in cycle.

Description

technical field [0001] The invention relates to a biogas fermentation system. Background technique [0002] With the development of our country's economy and social progress, the life of urban residents has been further improved, but there are still many problems in the life of rural residents. In order to build a well-off society in an all-round way, it is very necessary to build a new socialist countryside. This requires the grand goal of developing rural ecological agricultural production methods, improving the rural environment, and increasing farmers' income. Among them, the comprehensive utilization of biogas digesters is an important way to change the rural environment. The construction of a biogas digester can be used for about 20 years. Comprehensive utilization of biogas digesters can not only save energy, improve and protect the environment, but also save chemical fertilizers and pesticides, improve crop yield and quality, and promote and drive the development o...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the biogas liquid in the traditional biogas tank has poor fluidity and is easy to crust, and the fermentation raw materials and strains are unevenly distributed in the biogas tank, resulting in low gas production efficiency and low utilization rate of fermentation raw materials
