Straight cylinder hydraulic methane fermentation device

Abstract

The invention discloses a straight tube type hydraulic type super-effective methane fermentation device. The straight tube type hydraulic type super-effective methane fermentation device comprises a feeding pipe, a discharge pipe, a fermentation pipeline and a water pressure chamber, wherein the fermentation pipeline is a linear type pipeline, openings are respectively formed in the top parts of the two end sides of the fermentation pipeline and are respectively detachably connected with the feeding pipe and the discharge pipe, the side walls of the feeding pipe and the discharge pipe extend below the liquid level of biogas slurry in the fermentation pipeline, the water pressure chamber is mounted at the top part of the fermentation pipeline, a horizontally arranged water drainage pipe of the feeding pipe is connected between the water pressure chamber and the feeding pipe, and a horizontally arranged water drainage pipe of the discharge pipe is connected between the water pressure chamber and the discharge pipe; a plurality of gas baffles which are arranged between the side walls of the feeding pipe and the discharge pipe are also arranged in the fermentation pipeline, a fermentation region is formed in a space between the side wall of the feeding pipe / the discharge pipe and the adjacent gas baffle or between every two adjacent gas baffles, the top part of each fermentation region is communicated with an independent airway, and a valve body is arranged on each airway. According to the straight tube type hydraulic type super-effective methane fermentation device disclosed by the invention, the circulation flow stirring performance of the biogas slurry is strong, strains are promoted to be uniformly distributed by utilizing flow stirring of the biogas slurry, a fermenting material is also promoted to go deep into a fermentation system, the fermentation efficiency of the system is improved, and the gas production of the 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
