technical field

The utility model belongs to the technical field of biogas production and manufacture, and relates to a biogas tank.

Background technique

The biogas tank is mainly made of a closed tank, which can process organic waste, straw, and manure to generate biogas and fertilizer. However, a certain temperature is required to generate biogas, and the winter temperature in northern regions is too low, which limits biogas production. At present, there is a way to heat the biogas tank with hot water generated by a solar collector. It is mainly composed of a solar collector, a heat exchanger and a biogas tank with a heating pipe. The solar collector heats the medium and exchanges heat. The heat exchanger and the heating water pipe of the biogas tank constitute a water circulation system. The heat medium exchanges heat with the water in the water circulation system in the heat exchanger, and the hot water flows through the heating water pipe of the biogas tank to heat the biogas tank. However, during the time period when the biogas tank needs to be heated in winter, the heat energy generated by the solar collector is small, which cannot meet the temperature requirements of the biogas tank.
