Phase change heat storage biogas device for increasing solar energy utilization rate

Abstract

The invention discloses a phase change heat storage biogas device for increasing the solar energy utilization rate. The phase change heat storage biogas device comprises a biogas tank, a phase change material, dyestuff, an antireflection film and a heat preservation quilt. The outer wall of the biogas tank is covered with the phase change material, the dyestuff is mixed in the phase change material, the outer side of the phase change material is evenly wrapped by the antireflection film, and when heat needs to be released after the phase change material absorbs heat, the outer side of the antireflection film is covered with the heat preservation quilt. A proper temperature environment can be provided for microbial fermentation in the biogas tank, biogas generating continuity is improved, the biogas yield is increased, the process is simple, and operation is easy.

Description

technical field

[0001] The invention relates to the field of biogas devices, in particular to a phase-change thermal storage biogas device for improving solar energy utilization. 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, and pH. Biogas can be used as a living fuel. With the continuous development of my country's economy, the use of biogas technology is also being popularized and developed. More and more people start to use biogas digesters or biogas tanks. Feces and other materials are put into biogas digesters or biogas tanks for fermentation to produce biogas, which are transported through pipelines for human use. However, biogas digesters or biogas tanks are easily affected by the external temperature, especially in winter, when the temperature is low, the internal fermentation is not sufficient , especially in the north, the...
