An eco-friendly digester

Abstract

The invention discloses an ecological and environment-friendly methane tank, which sequentially comprises a gas storage chamber, a fermentation chamber and a substrate chamber from top to bottom, wherein a feeding pipe is arranged in the methane tank; a water pressure chamber is arranged at the outer side; a manure storage tank is arranged at the lateral side of the water pressure chamber; the lateral side of the manure storage tank communicates with a material extraction tank; the methane tank is formed by a three-layer structure; the outermost layer is a heat insulation layer; the middle layer is a vacuum layer; the innermost layer is a heating layer; a backflow pipe is also arranged between the feeding pipe and the material extraction tank; a material pushing mechanism is arranged in the backflow pipe; a material extraction passage is arranged between the material extraction tank and the substrate chamber; a vertical rotation stirring mechanism is arranged in the fermentation chamber. The ecological and environment-friendly methane tank solves the problems of low fermentation efficiency and incomplete fermentation in the prior art; in addition, the goal of cyclic fermentation can be achieved in a backflow mode, so that the fermentation is more thorough; the backflow is smooth; the backflow blockage problem does not exist; meanwhile, the problems of fermentation interruption and methane gas supply interruption due to the temperature reduction in the methane tank in winter are solved.

Description

technical field [0001] The invention relates to an ecological environment-friendly methane pool. Background technique [0002] Biogas: It is a combustible gas produced by microbial fermentation of organic matter in an anaerobic environment under certain conditions of temperature, humidity, and pH. [0003] The current agriculture focuses on ecologically integrated agriculture, which integrates livestock, vegetables, and plant cultivation, and fertilizes or ferments livestock manure to generate biogas, providing cheap and high-quality fuel for rural areas, and solving the problem of large amounts of manure that cannot be solved in time Dealing with the problem, environmental protection, sanitation. [0004] The existing biogas digesters are not equipped with efficient stirring facilities during the fermentation process, resulting in slow fermentation speed, low fermentation efficiency, long fermentation time, and incomplete fermentation; secondly, the existing biogas digeste...

AI Technical Summary

Problems solved by technology

[0006] In view of the above-mentioned problems, the present invention aims to provide an ecological environment-friendly biogas digester, which not only solves the existing problems of low fermentation efficiency and incomplete fermentation, but also achieves the purpose of cyclic fermentation through reflux, It makes the fermentation more thorough, and the backflow is smooth, and there is no problem of backflow blockage. At the same time, it also solves the problems of fermentation interruption and biogas supply interruption caused by the temperature drop in the biogas digester in winter
