High-efficiency methane generation system connected to the fermentation zone to promote flow and agitation

Abstract

The invention discloses an efficient methane generation system communicated with a fermentation area to promote flow stirring. The system comprises a feed pipe, a discharge pipe, a fermentation pipeline and a hydraulic chamber. The fermentation pipeline is a linear pipeline. The side tops of the two ends of the fermentation pipeline are provided with openings and detachably connected with the feed pipe and the discharge pipe respectively. The side wall of the feed pipe and the side wall of the discharge pipe extend to the position below the biogas slurry surface in the fermentation pipeline. The hydraulic chamber is installed on the top of the fermentation pipeline. A horizontally placed feed pipe drainage pipe is connected between the hydraulic chamber and the feed pipe. A horizontally placed discharge pipe drainage pipe is connected between the hydraulic chamber and the discharge pipe. A plurality of methane baffles located between the side wall of the feed pipe and the side wall of the discharge pipe are arranged in the fermentation pipeline. A fermentation area is formed in the space between the side wall of the feed pipe / discharge pipe and the methane baffle adjacent to the side wall, or in the space between every two adjacent methane baffles. The tops of the fermentation areas are communicated with independent methane guide pipes respectively. The methane guide pipes are provided with valves. Biogas slurry flows circularly, the stirring property is high, flow stirring of biogas slurry prompts uniform distribution of strains, raw fermentation materials are made to enter a fermentation system deeply, and the fermentation efficiency and methane yield 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
