Full-fermentation non-crusting methane device

Abstract

The invention discloses a full-fermentation non-crusting methane device. The full-fermentation non-crusting methane device is composed of a base, a fermentation tank body and a top cover, wherein the fermentation tank body is connected to the upper surface of the base, a slag hole and a drain valve are formed in and arranged at the bottom of the fermentation tank body, a heating device is arranged on an inner wall of the tank body, a fermentation chamber is formed in the inner space, the top cover is connected to the top of the fermentation tank body, return pipes and feed ports are arranged on and formed in the top cover, the feed ports are connected with feed port covers, a gas storage chamber is formed below the center feed port cover, an anti-floating grate is arranged at the bottom of the center feed port cover, and a gas guide pipe is connected to the center feed port cover. The full-fermentation non-crusting methane device has the advantages of novel design, no crusting of fermentation of raw materials, no need of stirring, high feed speed, good compression resistance, insulation and sealing performances, less heat loss and high gas yield and can be normally used in winter, the materials are simultaneously fed through a plurality of feed ports, and the methane raw materials, especially straws are manually compressed from the plurality of feed ports, so that the dry matter content of methane is increased.

Description

technical field [0001] The invention relates to the technical field of biogas engineering, in particular to a full-fermentation non-crust biogas device. Background technique [0002] At present, my country's biogas industry is very backward. There are tens of thousands of large and medium-sized biogas projects, most of which cannot operate normally, wasting tens of billions of yuan. The main reason is that the gas production rate per effective volume of fermentation is low; Factors are the dry matter content of biogas raw materials per unit fermentation volume, temperature, bacteria species, etc. Among them, the bacteria species are mostly old biogas residues and biogas liquids, which are relatively easy to obtain. Biogas raw materials are mainly crop straw, human and animal manure, organic waste, etc., and the resources are very rich. But it is currently the main source of pollution in our country. [0003] How to increase the dry matter content of biogas raw materials per u...
