Marsh gas production system and marsh gas production method thereof

Abstract

The invention discloses a marsh gas production system, which comprises a domestic garbage screening box, a garbage box transfer vehicle, a garbage crushing device, a straw dry process anaerobic fermentation device, a marsh gas storage device, a marsh gas biological desulphurization device, a marsh gas pressurization treatment device, a marsh gas purification device and a marsh gas refilling can. The marsh gas production system has the beneficial effects that the structure is simple; the fermentation efficiency is high; the assembly is convenient; the operation is simple and fast; through the domestic garbage screening box, the garbage is treated in a classified way; the garbage is transferred to a garbage station through the garbage box transfer vehicle; the garbage is crushed through thegarbage crushing device; the crushed garbage is poured into the straw dry process anaerobic fermentation device to be fermented; the fermented marsh gas is introduced into the marsh gas storage deviceto be collected; the collected marsh gas is subjected to desulphurization and dewatering through the marsh gas biological desulphurization device; the marsh gas subjected to desulphurization and dewatering is introduced into the marsh gas pressurization treatment device for pressurization; the pressurized marsh gas is purified through the purification device; the purified marsh gas is input intothe marsh gas refilling can.

Description

technical field [0001] The invention relates to the technical field of biogas production from garbage, in particular to a biogas production system. 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 producing biogas from garbage has complex structure, low fermentation efficiency, cumbersome operation, and inconvenient assembly, resulting in low production efficiency. Contents of the invention [0004] The purpose of the present invention is to provide a biogas production s...
