Abstract

The invention discloses an efficient environment-friendly straw methane tank used in rural areas, which includes a tank body, a charging tank and a discharging tank, wherein the charging tank and the discharging tank are respectively mounted on two sides of the tank body; the upper part of the tank body is an acidification tank, and the lower part of the tank is a fermentation tank separated from the acidification tank; a gas outlet of the fermentation tank extends out of the acidification tank and is flush with a tank port of the acidification tank; two sides of the fermentation tank are respectively connected with the discharging tank and the charging tank; a first discharge port is arranged on one side at the bottom part of the acidification tank; the first discharge port is connected with a vacuum pump; and moreover, a second discharge port is mounted at the upper end of vacuum pump and is communicated with the charging tank. According to the invention, the whole tank body is divided into two parts, namely the upper part and the lower part, the upper part is acidification tank while the lower part is the fermentation tank, as a result, solid-liquid separation and acidification-fermentation separation are realized, discharging of the methane tank is facilitated, the age-old problem of difficulty in discharging is solved, and further, the straw methane tank solves the problems of difficult management and the like in case of multi-day gas usage stop because the movable cover of the methane tank is opened due to large-volume of discharge in two seasons every year.

Description

technical field

[0001] The invention relates to the field of biogas digesters, in particular to a high-efficiency and environment-friendly straw biogas digester for rural areas. Background technique

[0002] Biogas is a combustible gas produced by microbial fermentation of organic matter in an anaerobic environment under certain conditions of temperature, humidity, and pH. Since this gas was first found in swamps, lakes, and ponds, people call it biogas. The construction of straw biogas digesters is one of the important ways to solve the problem of rural fuel. The biogas residue cannot be discharged directly by the suction and discharge truck of the fecal biogas digester. The discharge of straw biogas residue has become one of the key issues in the promotion of straw biogas. The stop of gas output has caused difficulties in management. After the transfer of labor force in rural areas, the breeding industry has declined, resulting in insufficient fermentation materials for b...
