Split-type heating methane tank

Abstract

The invention discloses a split-type heating methane tank, which comprises a methane tank and an efficient methane reactor. The split-type heating methane tank is characterized in that a heat exchanger is arranged inside the efficient methane reactor; an insulating layer is arranged at the outside the efficient methane reactor; discharge and feeding pipes are connected with the methane tank; an escape pipe is connected with the escape pipe of the methane tank; a water pump is assembled on a feeding pipe of the efficient methane reactor; a temperature sensor of a temperature controller is arranged inside the efficient methane reactor; the temperature controller is connected to the water pump; and the heat exchanger in the efficient methane reactor is connected with hot water inlet and outlet pipes. The split-type heating methane tank has the beneficial effects that the efficient methane reactor is added to a common methane tank to heat; the improvement on the common methane tank is facilitated; the construction cost of heating and heat preservation is reduced; the temperature in the efficient methane reactor is ensured by heating; the temperature in the methane tank is also improved at the same time; and the methane gas yield is increased. The split-type heating methane tank plays a stirring role through circulation of the water pump and ]methane fermentation is promoted.

Description

technical field [0001] The invention relates to a biogas generating device, in particular to a split-type temperature-increasing biogas pit. Background technique [0002] Biogas is a renewable energy source produced by the fermentation of organic matter in digesters. Temperature is one of the key factors affecting the gas production rate of biogas fermentation. When the temperature of the biogas digester is above 15°C, biogas fermentation can proceed well, and 35°C is a peak of biogas fermentation gas production. The temperature in the digester changes with the seasons. The winter in northern my country is cold and long, the air temperature and surface temperature are low, and the gas production rate of biogas digesters is low, which cannot meet the needs of farmers, resulting in a large number of idle rural biogas digesters in winter. Even in summer, due to the influence of ground temperature, the temperature in the biogas digester is not high, and the gas production rate...

Problems solved by technology

If it is to increase the temperature and heat preservation of the biogas digester that has been built, it is necessary to dig the biogas digester again for construction, which will increase the difficulty
