Device for heating methane tank

Abstract

The invention discloses a device for heating a methane tank. The device for heating the methane tank comprises a methane wall hanging stove; a hot water outlet pipe of the methane wall hanging stove is provided with a heat exchange coil pipe; the heat exchange coil pipe is arranged in a heating water tank; a water return pipe of the heat exchange coil pipe is connected to a cold water inlet pipe of a water replenishing hopper of the wall hanging furnace; one side of the heating water tank is provided with a hot water pump; a water pipe is communicated between the water inlet of the hot water pump and the water outlet of the heating water tank; a water outlet pipe of the hot water pump is connected with a heater in the tank; a water return pipe of the heater in the tank is connected to the other side of the heating water tank through a sensor; and a water replenishing hopper of the water tank is arranged above the heating water tank. The device for heating the methane tank has a simple structure, and can be used safely and reliably, and effectively guarantee the year-round gas production rate of the methane tank.

Description

Technical field: [0001] The invention relates to heat exchange, in particular to a biogas pond heating device suitable for heating materials in the biogas pond in winter and increasing the biogas output. Background technique: [0002] With the development of large-scale industrialization and agricultural industrialization, the increasing shortage of non-renewable energy such as petroleum and coal, the utilization of biomass energy biogas is increasing. However, in northern China, due to the low temperature in winter, the amount of biogas produced will decrease Greatly reduced, affecting normal use, in order to increase biogas output, there are currently devices for heating biogas pits, but there is no easy-to-use device for biogas pit heating by biogas wall-hung boilers. Invention content: [0003] The object of the present invention is to provide a biogas pit heating device which uses a biogas wall-hung boiler as the main body to heat the biomass raw materials in the biog...

[0002] With the development of large-scale industrialization and agricultural industrialization, the increasing shortage of non-renewable energy such as petroleum and coal, the utilization of biomass energy biogas is increasing. However, in northern China, due to the low temperature in winter, the amount of biogas produced will decrease Greatly reduced, affecting normal use. In order to increase biogas production, there are devices for heating biogas digesters at present, but there is no easy-to-use device that uses biogas wall-mounted boilers to heat biogas digesters.
