Stirring-free dynamic dry anaerobic fermentation system

Abstract

The invention discloses a stirring-free dynamic dry anaerobic fermentation system. The stirring-free dynamic dry anaerobic fermentation system comprises an anaerobic reactor and a base, the anaerobic reactor is vertically fixed on the base through a plurality of support columns, the length direction of the anaerobic reactor is taken as forward and backward directions, an anaerobic reaction chamber is arranged in the anaerobic reactor along the length direction, the top surface of the anaerobic reaction chamber is in an arc structure, the bottom surface of the anaerobic reaction chamber is semicircular and is slantly arranged in such a way that the front part is higher and the rear part is lower, the included angle between the bottom surface of the anaerobic reaction chamber and the horizontal plane is 10 degrees to 18 degrees, methane discharge holes and biogas liquid spraying holes are formed in the top part of the anaerobic reactor, a plurality of rows of methane ejection sections and biogas liquid ejection sections are distributed in a staggered manner at intervals at the bottom part of the anaerobic reactor in the length direction, the methane ejection section comprises a plurality of methane ejection holes distributed in the bottom part of the anaerobic reactor, and the biogas liquid ejection section comprises a plurality of biogas liquid ejection holes distributed in the bottom part of the anaerobic reactor. The stirring-free dynamic dry anaerobic fermentation system is reasonable in structure design, good in anaerobic fermentation effect and large in processing quantity, and the perishable substances like kitchen wastes, straws, faeces and the like are continuously effectively converted into clean energy methane.

Description

technical field [0001] The invention belongs to the technical field of garbage treatment, and in particular relates to a non-stirring dynamic dry anaerobic fermentation system. Background technique [0002] my country produces no less than 60 million tons of kitchen waste, 100 million tons of farming waste, and more than 200 million tons of agricultural and forestry waste every year. Due to the high moisture content, high organic matter content, and a large amount of biomass energy in the kitchen waste, if the kitchen waste is not treated, it will pollute the environment, spread diseases, and affect food safety, which is extremely harmful. . The "garbage pigs" and "gutter oil" caused by kitchen waste are long-standing social chronic diseases in various parts of our country, posing a serious threat to food safety, and have become a hot issue that has been widely concerned by all walks of life in recent years. [0003] At present, people use various means to turn kitchen was...

Problems solved by technology

In addition, there are many devices in the existing anaerobic fermentation device in the fermentation room. When there is a problem with these devices, it is necessary to clean up all the materials in the fermentation room before operating. The labor intensity is high, which affects the normal operation of the operation.
