Biogas digester with dry and wet separation function against waste materials

Abstract

The invention provides a biogas digester with a dry and wet separation function against waste materials, belonging to the technical field of preparation of biogas. The biogas digester solves the technical problems that the treatment of the waste materials is more troublesome, the biogas poisoning is easy to cause and the like of the existing biogas digester. The biogas digester with the dry and wet separation function against the waste materials comprises a fermentation tank and a feed port connected with the fermentation tank, wherein a feed tank is connected with a filter box hung in the fermentation tank, an inner cavity of the filter box is communicated with the feed port, a plurality of filter holes communicating the inner cavity of the filter box with the fermentation tank are formed in the outer wall of the filter box, the biogas digester further comprises a wastewater treatment tank and a residue treatment tank, the residue treatment tank is connected with the filter box, and the wastewater treatment tank is connected with the fermentation tank. The biogas digester provided by the invention has the advantages of performing dry and wet separation on the waste materials, improving the safety of the biogas digester and the like.

Description

technical field [0001] The invention belongs to the technical field of biogas preparation, and relates to a biogas digester with the function of separating dry and wet waste. Background technique [0002] Biogas is a combustible gas produced by microbial fermentation of organic matter in an anaerobic environment under certain temperature, humidity, and pH conditions. Since this gas was originally found in swamps, lakes, and ponds, So people call it biogas. [0003] Biogas contains a variety of gas components, the main component is methane (CH4). The process in which biogas bacteria decompose organic matter and produce biogas is called biogas fermentation. According to the role of various bacteria in the biogas fermentation process, biogas bacteria can be divided into two categories. The first type of bacteria is called decomposing bacteria, and its function is to decompose complex organic matter into simple organic matter and carbon dioxide (CO2). Among them, there are b...

Problems solved by technology

[0004] After the biogas digester ferments domestic garbage and feces to produce biogas, a large amount of biogas waste is left. The traditional method of discharging waste from the biogas digester is to open the cover of the biogas digester to extract the waste. However, due to the large amount of non-decomposable impurities in the waste , using the waste water pump to pump out the waste water pump will cause blockage of the waste water pump, and the waste cannot be handled lightly. Moreover, biogas poisoning incidents frequently occur, and it is very dangerous for the human body to directly breathe the gas near the opened biogas pit. In order to solve the above problems, the present invention Improvement of biogas digesters
