Description

a biogas generator

technical field

The invention relates to the technical field of biogas, in particular to a biogas generator.

Background technique

As a new clean energy, biogas can be widely used in rural areas of our country. It uses the waste straw of crops to produce biogas as an energy source for cooking, heating water, lighting, etc., which can save a lot of coal, fuel and Firewood, etc., and can improve the environment, high thermal efficiency, because of its environmental protection and practicality, more and more people's attention.

Traditional concrete biogas digesters have problems such as difficult construction, difficult maintenance, short service life, large land occupation, and inconvenient factory mass production.
