Description

Technical Field

[0001] The utility model relates to the technical field of fermentation tanks, in particular to a heating device for an anaerobic fermentation tank. Background Art

[0002] An anaerobic fermentation tank is an important equipment for carrying out biological fermentation processes in an oxygen-free environment. It is usually made of materials such as stainless steel and has good sealing properties to ensure an oxygen-free state inside. Anaerobic fermentation tanks play a key role in many fields. In the field of environmental protection, they are used to treat organic waste and convert it into renewable energy such as biogas; in the food industry, they can be used to produce certain specific fermented foods; in industrial wastewater treatment, anaerobic fermentation tanks can help reduce the organic matter content in wastewater and reduce pollution emissions. During the fermentation process, in order to maintain the smooth progress of the fermentation reaction, special attention must be paid to the temperature of the fermentation tank. Traditional anaerobic fermentation equipment uses boiler heating to increase the temperature inside the anaerobic fermentation equipment. This heating method consumes more fuel resources and is relatively wasteful.

[0003] The existing announcement CN208649299U provides a heating device for an anaerobic fermentation tank. The heating device is a waterless heating device. The air in the solar vacuum tube is used as the heat medium. The air in the solar vacuum tube is heated by the sun and exchanges heat with the evaporator in the air source heat pump. The heat energy is then released through the coil on the outside of the anaerobic fermentation tank to achieve the purpose of heating the anaerobic fermentation tank.
