Water-pressure separation type methane-generating tank

Abstract

The invention relates to a water-pressure separation type methane-generating tank. The water-pressure separation type methane-generating tank is characterized in that a tank body is provided with a cover plate; the cover plate is provided with a water-pressure tank and a methane opening higher than the water-pressure tank; a baffle plate is arranged at the bottom part of the tank body and separates the tank body into a solid area and a liquid area with non-communicated bottom parts; a slag feeding pipe and a slag discharging pipe are inserted into the solid area; a liquid feeding pipe is inserted into the liquid area; the lower end part of the liquid feeding pipe is lower than the top part of the baffle plate; the upper end part of the slag discharging pipe is higher than the top part of the water-pressure tank; floating devices are arranged on the slag feeding pipe and the liquid feeding pipe and are positioned in the water-pressure tank. The water-pressure separation type methane-generating tank has the advantages that solid slag is introduced into the solid area by the slag feeding pipe, liquid materials are introduced into the liquid area by the liquid feeding pipe, and the solid slag in the solid area is positioned at the bottom part and can not enter the liquid area; after fermentation, since the solid slag is not completely utilized, the liquid materials are pumped out by the liquid feeding pipe, the solid slag is remained, and new liquid materials are introduced for repeated fermentation, so that the utilization rate of the solid slag can be increased, solid and liquid can be effectively separated and pumped, and the utilization rate can be increased.

Description

technical field [0001] The invention relates to a biogas digester, in particular to a water pressure separation type biogas digester. 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. Because this gas was first found in swamps, lakes, and ponds, people called it biogas. [0003] Biogas contains a variety of gas components, the main component is methane. 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. Among them, there are bacteria that specialize in decomposing cellulose, call...
