Methane generating system for stirring and distributing strains by pushing biogas slurry to circularly flow by virtue of air pressure

Abstract

The invention discloses a methane generating system for stirring and distributing strains by pushing biogas slurry to circularly flow by virtue of air pressure. The methane generating system comprises a feeding pipe, a discharging pipe, a fermentation pipeline and a water pressure chamber, wherein the fermentation pipeline is a linear type pipeline, openings are formed in two end sides of the fermentation pipeline, the feeding pipe and the discharging pipe are respectively detachably connected to the two end sides of the fermentation pipeline, the side wall of the feeding pipe and the side wall of the discharging pipe stretch below the liquid level of the biogas slurry in the fermentation pipeline, and the water pressure chamber is mounted on the top of the fermentation pipeline; a horizontally placed feeding pipe draining pipe is connected between the water pressure chamber and the feeding pipe, and a horizontally placed discharging pipe draining pipe is connected between the water pressure chamber and the discharging pipe; a plurality of gas baffles 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 region is formed between the side wall of a feeding pipe / discharging pipe and an adjacent gas baffle or formed between the every two adjacent gas baffles, an independent gas guide tube is communicated to the top of each fermentation region, respectively, and a valve body is arranged on each gas guide tube. According to the methane generating system, the circular flow stirring performance of the biogas slurry is high; by stirring by virtue of the flow of the biogas slurry, the uniform distribution of the strains is promoted, and a fermentation raw material is deeply fed to a fermentation system, so that the fermentation system of the methane generating system is improved, and the gas output of the methane generating system is increased.

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
