Method for producing methane with detachable new methane generator with inlet and outlet pipes

Abstract

The invention discloses a method for producing methane by virtue of a novel methane generating device with detachable feeding and discharging pipes. The method comprises the following steps: pouring a fermentation raw material into a fermentation system for fermenting to produce marsh gas, collecting marsh gas in a fermentation region formed between the side wall of a feeding pipe / discharging pipe and an adjacent gas baffle or a fermentation region formed between the every two adjacent gas baffles, increasing the air pressure of marsh gas in the fermentation region to push biogas slurry in a fermentation pipeline to flow to the feeding pipe and the discharging pipe and flow into a water pressure chamber through a feeding pipe draining pipe and a discharging pipe draining pipe; decreasing the air pressure of marsh gas in any one fermentation region to enable the biogas slurry stored in the water pressure chamber to flow back into the fermentation pipeline through the feeding pipe draining pipe and the discharging pipe draining pipe, thereby realizing the circular flow of the biogas slurry; utilizing marsh gas in other fermentation regions; circularly producing marsh gas and using marsh gas according to the foresaid steps.

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
