Automatic uniform feeding method for anaerobic jar used for preparing methane with straws

Abstract

An automatic uniform feeding method for an anaerobic jar used for preparing methane with straws is characterized in that a charging tank (24) is connected with the anaerobic jar (12) through a charging pipe, wherein the anaerobic tank (12) is connected with a float liquid level meter (22) through a reflowing pipe (20); the float liquid level meter (22) is connected with the charging tank (24) through a liquid conveying pipe (23) and communicates with a pressure gas pipe (7); a charging valve (6) is mounted on a pipeline of the charging pipe (4); a reflowing valve (19) is mounted on the pipeline of the flowing pipe (29); a pressure gas pipe valve (5) is mounted on the pipeline of the pressure gas pipe (7); the charging pipe (4) is connected with a charging spray head (25) and is connected from the upper part of the anaerobic jar (12) into an inner chamber (Q) of the anaerobic jar; the material methane is uniformly sprayed and distributed in sector shape into the inner tank (Q) of the anaerobic jar through the charging spray head (25). Materials are fed and distributed uniformly, the reaction speed is high, circumstances of flocking together and crusting can be decreased, the capacity utilization rate of the inner tank (Q) of the anaerobic jar is increased,the preparation quality is improved,the efficiency is improved,and the methane output is increased.

Description

technical field [0001] The invention relates to a method for producing biogas by fermenting straw, in particular to an automatic feeding method for an anaerobic fermentation tank. Background technique [0002] At present in China, the anaerobic production of biogas from straw generally adopts the feeding fermentation process in the anaerobic tank. Accumulation, the debris at the back enters the anaerobic tank and accumulates on the front pile, forming a phenomenon of clustering and crusting. Due to the large inner volume of the anaerobic tank, the inside of the anaerobic tank is in a closed state and cannot be adjusted by external force. It can only rely on the gravity of the straw debris to fall by itself. The uneven distribution of the debris in the anaerobic tank causes the materials to get together The degree of heating and fermentation of the crust is not uniform, the reaction speed is slow, the quality of the biogas produced is affected, the utilization rate of the in...

Due to the large inner volume of the anaerobic tank, the inside of the anaerobic tank is in a closed state and cannot be adjusted by external force. It can only rely on the gravity of the straw debris to fall by itself. The uneven distribution of the debris in the anaerobic tank causes the materials to get together The degree of heating and fermentation of the crust is uneven, the reaction speed is slow, the quality of biogas production is affected, the utilization rate of the internal volume of the anaerobic tank is low, and the production efficiency is difficult to improve
