Double-tube bundled methane generation system with multi-region mixed flow bacteria

Abstract

The invention discloses a binocular bundled methane generation system capable of realizing multi-area mixed flowing bacteria distribution. The methane generation system comprises a feeding pipe, a discharge pipe, a fermentation pipeline and a water pressure room, wherein the fermentation pipeline is a straight pipeline; openings are formed in the top parts of two end sides of the fermentation pipeline, and can be detachably connected with the feeding pipe and the discharge pipe respectively; the side wall of the feeding pipe and the side wall of the discharge pipe extend to below the liquid level of biogas slurry in the fermentation pipeline; the water pressure room is arranged at the top part of the fermentation pipeline; a horizontally arranged feeding pipe drain pipe is connected between the water pressure room and the feeding pipe; a horizontally arranged discharge pipe drain pipe is connected between the water pressure room and the discharge pipe; a plurality of air baffle plates between the side wall of the feeding pipe and the side wall of the discharge pipe are also arranged in the fermentation pipeline; a fermentation area is formed by a space between the side wall of the feeding pipe / discharge pipe and the adjacent air baffle plates or between the adjacent air baffle plates; the top parts of the fermentation areas are respectively communicated with independent air guide pipes; and a valve body is arranged on each air guide pipe. The circular flow stirring property of the biogas slurry is high; uniform distribution of the strains is promoted by biogas slurry flow stirring; penetration of a fermentation raw material into the fermentation system is promoted; and the fermentation efficiency and the biogas production rate of the system are improved.

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
