Description

technical field [0001] The invention relates to the field of new energy and fermentation, in particular to a microbial fermentation treatment system for fermentation of raw materials such as straw and animal manure. Background technique [0002] The air ducts of the existing biogas fermentation systems are mostly poured with concrete and fixed on the top of the gas storage plate, and the airtightness of the surrounding is not high, and the air leakage around the surrounding is difficult to block; since the fermentation raw materials of the biogas digester are mostly livestock manure, manure During the decay process, various insects are easy to breed, and maggots crawl into the airway tube and cause blockage, which is difficult to clean; when there is water in the airway tube, it is difficult to discharge; the most prominent problem is that when the airway tube breaks, it is difficult to replace and can Lead to the scrapping of the whole biogas fermentation system.

[0002] The air ducts of the existing biogas fermentation systems are mostly poured with concrete and fixed on the top of the gas storage plate, and the airtightness of the surrounding is not high, and the surrounding air leakage is difficult to block; since the fermentation raw materials of the biogas digester are mostly livestock manure, manure During the decay process, various insects are easy to breed. Maggots crawl into the airway tube and cause blockage, which is difficult to clean; when there is water in the airway tube, it is difficult to discharge; the most prominent problem is that when the airway tube breaks, it is difficult to replace and can Lead to the scrapping of the entire biogas fermentation system

[0003] The biogas storage space of the current hydraulic biogas fermentation system refers to the area between the gas baffles of the feed pipe and the gas baffles of the discharge pipe arranged at both ends of the fermentation chamber. When the stored biogas is not used for a long time, The stored biogas overflows from the bottom of the feed pipe air baffle, discharge pipe air baffle, and enters the air, causing waste; the existing biogas storage space is limited

[0004] The most important factors affecting biogas fermentation efficiency and gas production are fermentation raw materials, strains, and temperature. When the fermentation raw materials and strains are evenly distributed, microorganisms can fully decompose the fermentation raw materials, produce more biogas and make the temperature in the biogas storage chamber increase to further promote fermentation; in the existing biogas fermentation system, due to the poor fluidity of the biogas slurry, a large amount of fermentation raw materials are accumulated at the inlet. After long-term fermentation, the biogas slurry containing a large number of bacteria mainly accumulates at the outlet. As a result, the distribution of fermentation raw materials and strains in the fermentation system is uneven, which inhibits the fermentation efficiency and reduces the gas production.
