A method for producing methane with a double-barrel bundled generation system with multi-region mobile cloth bacteria

Abstract

The invention discloses a method for producing methane by employing a binocular bundled methane generation system capable of realizing multi-area mixed flowing bacteria distribution. The method comprises the following steps: a fermentation raw material is poured into a fermentation system to be fermented to generate a biogas, the biogas in gathered in a fermentation area formed by a space between the side wall of a feeding pipe / discharge pipe and adjacent air baffle plates or a space between the adjacent air baffle plates, and pressure of the biogas in the fermentation area is increased to push biogas slurry in a fermentation pipeline to flow towards the feeding pipe, the discharge pipe and a bacteria distribution device and to flow into a water pressure room through a feeding pipe drain pipe, a discharge pipe drain pipe and the bacteria distribution device; 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, the discharge pipe drain pipe and the bacteria distribution device 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] Biogas digesters change the old living habits of farmers and improve the living environment in rural areas. The biogas digesters are built together with toilets and pigpens, which are not easy to breed mosquitoes and have no odor. It will play an important role in eradicating infectious diseases such as schistosomiasis and hookworm. In addition, due to frequent human activities, a large amount of energy consumption, and a large amount of open-air stacking of straw and livestock and poultry manure, etc., have caused a large amount of carbon dioxide emissions and aggravated the greenhouse effect. The use of biogas digesters can reduce the above problems to a certain extent. [0003] Promote the development of ecological agriculture and animal husbandry The waste from the biogas digester is biogas slurry and biogas residue, which can be used as pesticide additives, fert...

AI Technical Summary

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
