Method for generating new energy through fermentation via organic waste fermentation treatment device

Abstract

The invention discloses a method for generating new energy through fermentation via an organic waste fermentation treatment device. Fermentation raw materials are poured into a fermentation chamber through a feeding pipe and ferment in the fermentation chamber, so that marsh gas is generated; due to influence of such factors as the fermentation raw materials, strains and the temperature, the amount of marsh gas collected in all fermentation areas in a gas storage plate is different, thus the air pressure difference is generated between every two adjacent fermentation areas, and convection of biogas slurry is promoted; each fermentation area is connected with an auxiliary gas storage device and a gas guiding device, each gas guiding device is provided with a gas guiding pipe through a luting structure, when one gas guiding pipe ruptures or is blocked, replacement or dredging is convenient to conduct, and in addition, whether air leakage exists or not can be observed through a moistening layer arranged on the upper portion of each luting layer; the auxiliary gas storage device is of a separated hydraulic pressure structure, the marsh gas storage space is expanded, and in addition, structural stability is high.

Description

technical field [0001] The invention relates to a field of new energy and fermentation, in particular to a methane fermentation system. 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. Insects 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 be removed. Lead to the scrapping of the whole biogas fermentation system. [0003] The biogas storage space of the current hydraulic biogas fermentation sy...

[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.
