Abstract
Description
technical field
[0001] The invention relates to the technical field of biogas pits, in particular to a temperature-increasing and heat-retaining biogas pit. Background technique
[0002] The biogas digester can be used for about 20 years. Making good use of the biogas digester can not only save energy, improve and protect the environment, but also save chemical fertilizers and pesticides, improve the yield and quality of crops, and promote and drive the development of the breeding industry. A septic tank filled with human and animal feces, straw and other organic substances, and the mouth of the tank is sealed; under suitable conditions, the flammable gas produced; through the fermentation of biogas in the biogas digester, a clean and hygienic new biogas energy is formed; however, today's There are also various problems in the biogas digester, especially in winter in the north, due to the drop in temperature, the fermentation in the pond slows down, resulting in a small amou...
