Household garbage biogas production system

Abstract

The invention discloses a household garbage biogas production system which comprises a household garbage screening tank, a garbage can transferring vehicle, a garbage crushing device, a straw dry-method anaerobic fermentation device, a biogas storage device, a biogas biological desulfurizer, a biogas pressurizing treatment device, a biogas purification device and a biogas refilling tank. The household garbage biogas production system has the beneficial effects of being simple in structure, high in fermentation efficiency, convenient to assemble and simple and convenient to operate, garbage isclassified through the household garbage screening tank, the garbage is transferred to a garbage station through the garbage can transferring vehicle, the garbage is crushed through the garbage crushing device, the crushed garbage is poured into and fermented in the straw dry-method anaerobic fermentation device, a biogas generated after fermentation is introduced into and collected by using the biogas storage device, the collected biogas is desulfurized and dehydrated by using the biogas biological desulfurizer, the desulfurized and dehydrated biogas is introduced into the biogas pressurizingtreatment device for pressurization, the pressurized biogas is purified by using the biogas purification device, and the purified biogas is input into the biogas refilling tank.

Description

technical field [0001] The invention relates to the technical field of biogas production from garbage, in particular to a biogas production system from domestic garbage. Background technique [0002] Biogas, as the name implies, is the gas in swampy wetlands. People often see that in swamps, sewers or cesspools, there are bubbles coming out. If we strike a match, it can be ignited. This is the naturally occurring methane. From the perspective of scientific definition, biogas is a kind of combustible gas produced by the fermentation of microorganisms under the isolation of air (reducing conditions) and the appropriate temperature and pH value of various organic substances. [0003] The currently used reaction system for making biogas from garbage has complex structure, low fermentation efficiency, cumbersome operation, and inconvenient assembly, resulting in slow production efficiency. Contents of the invention [0004] The purpose of the present invention is to provide a...
