Methane generator with double-pipe channel biogas slurry convection stirring

Abstract

The invention discloses a double-pipe channel type super-efficient biogas slurry convection stirring methane generating device which comprises a feeding pipe, a discharging pipe, a fermentation pipeline and a water pressure chamber. The fermentation pipeline is a linear pipeline, and openings are formed in the tops of the two end sides of the fermentation pipeline and are detachably connected with the feeding pipe and the discharging pipe respectively. The side wall of the feeding pipe and the side wall of the discharging pipe extend to the positions below the liquid surface of biogas slurry in the fermentation pipeline, and the water pressure chamber is mounted at the top of the fermentation pipeline. A feeding pipe drain pipe which is horizontally placed is connected between the water pressure chamber and the feeding pipe, and a discharging pipe drain pipe which is horizontally placed is connected between the water pressure chamber and the discharging pipe. A plurality of gas blocking plates which are located between the side wall of the feeding pipe and the side wall of the discharging pipe are further arranged in the fermentation pipeline. A fermentation area is formed in the space between the side wall of the feeding pipe / discharging pipe and the adjacent gas blocking plate, or fermentation areas are formed between the space between the adjacent gas blocking plates. The tops of all the fermentation areas are communicated with independent gas guide pipes, and valve bodies are arranged on the gas guide pipes. The circular flow stirring performance of the biogas slurry is high, strains are promoted to be evenly distributed by flowing and stirring of the biogas slurry, fermentation raw materials are promoted to go deep into the fermentation system, and the fermentation efficiency and the gas 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
