The invention discloses a method for preparing new energy from plant straw through anaerobic fermentation. The method comprises the steps that gas is guided, wherein a gas guide device is utilized for guiding out marsh gas in a gas storage plate, the gas pressure of the marsh gas in the gas storage plate is reduced, biogas slurry stored in a hydraulic pressure room flows back and flows into a feed inlet through a feed inlet drainage pipe in one way, and biogas slurry rich in strain is brought into the feed inlet; a material opening separation plate is opened for promoting bacteria distribution, wherein a circulation flowing hole is opened for achieving mutual convection of two ends, a stirring rod is utilized for stirring in a turbulence area, biogas residue precipitated near a discharge outlet is brought into the discharge outlet through movement in the direction from the feed inlet to the discharge outlet, biogas slurry rich in strain near the discharge outlet flows into the feed inlet through the circulation flowing hole, and uniform distribution of strains is promoted; in addition, a large amount of biogas residue can be taken out of the discharge outlet.
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. [0003] ...
