Biogas bio-fermentation preparation system

Abstract

The invention discloses a biogas bio-fermentation preparation system. The system contains a biogas bio-fermentation device, wherein the biogas bio-fermentation device is connected with a gas-water separation device, a safe exhaust device, a gas storage device, a purification and desulfurization device, a biogas special pressurization device and a biogas control valve in turn through a biogas special pipeline; and the biogas bio-fermentation device is provided with a gas outlet which is used to be connected with the biogas special pipeline, and the biogas bio-fermentation device is also provided with an automatic temperature control device. The system has the advantages of simple structure, automatic temperature control, safety in operation and stable gas supply.

Description

technical field [0001] The invention relates to a new energy preparation system, in particular to a biogas bio-fermentation preparation system. Background technique [0002] Biogas fermentation, also known as anaerobic digestion and anaerobic fermentation, refers to organic matter (such as human, livestock and poultry manure, straw, weeds, etc.) under certain moisture, temperature and anaerobic conditions, through the catabolism of various microorganisms, and finally The process of forming a flammable mixture of gases (biogas) such as methane and carbon dioxide. [0003] At present, the vast majority of biogas production in my country is realized by underground biogas digesters. Biomass raw materials are put into underground biogas digesters, biogas is produced through fermentation, and then the generated biogas is used in people's production and life through a series of auxiliary equipment. Life. This kind of biogas preparation system has the following disadvantages: 1. Th...

AI Technical Summary

Problems solved by technology

This kind of biogas preparation system has the following disadvantages: 1. The structure of the system is complex, and the buried biogas digester is not movable. It is generally built and used by families. It is time-consuming and laborious to build, and the scope of use is limited; Natural temperature fermentation is greatly affected by the external temperature. When the temperature is low, the fermentation work cannot be carried out, which cannot meet the requirements of producing biogas all year round; 3. The gas storage device is easily damaged, and the purity of the biogas is not high. It is easy to produce toxic gas, and the safety is not high; 4. The gas supply is not stable enough, and there are often phenomena such as gas failure
