Cold region methane generating system and cold region methane preparation method

Abstract

The invention provides a cold region methane generating system and a cold region methane preparation method, and relates to the technical field of methane preparation. The technical problem that methane cannot be produced in a cold region in winter is solved. The device comprises a primary fermentation device, a methane generator and a sunlight room, wherein the methane generator is arranged in the sunlight room; the primary fermentation device is connected with the methane generator; organic refuse is subjected to aerobic fermentation in the primary fermentation device and then enters the methane generator; the sunlight room rises the temperature of the methane generator; the temperature in the methane generator in the cold region in winter can reach the temperature required for methane generation; the organic refuse subjected to primary fermentation is subjected to anaerobic fermentation in the methane generator to generate methane. In addition, methane generation germs cultured by fruit and vegetable waste are used for fast raising the temperature of the materials in the methane generator, so that the stable methane generation in the cold region in winter can be ensured.

Description

technical field [0001] The invention relates to the technical field of biogas preparation, in particular to a cold area biogas generation system and a cold area biogas preparation method. Background technique [0002] Biogas is a combustible gas produced by microbial fermentation of organic matter in an anaerobic environment under certain conditions of temperature, humidity, concentration and pH. Usually, various organic matter such as human and animal manure, straw, kitchen waste, and domestic sewage can be placed in a closed biogas digester for fermentation, that is, it will be decomposed and transformed by a wide variety of biogas fermentation microorganisms, thereby producing biogas. As a kind of energy for life, biogas can be used for cooking, lighting, and water heaters. It can also be used as industrial energy, biogas power generation, greenhouse seedling raising, biogas chicken raising, biogas thermal energy processing, etc. Therefore, biogas enables agricultural or...
