Abstract

A solar heat-collecting applicator in marsh gas fermentation pool consists of solar heat collector (2), gas-storage tank (10), temperature adjuster (4) and marsh gas pool (11). The solar heat collector (2) is installed outside of marsh gas pool (11), discharging pipe on bottom of solar heat collector (2) is connected to entrance end of internal heat exchanger (7) of marsh gas pool (11) by valve, outlet pipe of heat exchanger (7) is connected to inlet pipe on top of solar heat collector (2) by circulating pump (5) and valve. It has higher fermentation temperature and more marsh gas output.

Description

[0001] Application field [0002] The invention relates to an application device of solar heat collection in a biogas fermentation tank, which is mainly used in the biogas fermentation project of large and medium-sized large-scale livestock and poultry farms, organic production enterprises, and rural straws, garbage, and feces in northern my country . Background technique [0003] Biogas and solar technology have been widely used in my country, but the application of solar heat collection technology in biogas fermentation tanks has not yet been reported and applied. [0004] As we all know, fermentation temperature is a key factor affecting the rate of biogas production, and it directly affects the digestion rate and gas production rate of raw materials. The temperature range of biogas fermentation is relatively large, and the temperature range at which methane bacteria can move is 4℃-72℃. The higher the temperature, the faster the fermentation rate of the fermentation raw material...
