Anaerobic fermentation device

Abstract

The invention discloses an anaerobic fermentation device. The anaerobic fermentation device comprises a tank, a carbonization assembly, an annular tube, sprayers, a stirring assembly, a circular culture assembly, cyclone separator and a controller, wherein the tank is provided with an interlayer tank; the carbonization assembly is arranged on the upper part of the tank and comprises a plurality ofcombustors; the combustors are arranged at intervals in the peripheral direction of the tank; the annular tube is arranged below the combustors; the sprayers are arranged on the annular tube at intervals and are downwards and obliquely arranged; the stirring assembly is arranged on the middle lower part of the tank; the circular culture assembly comprises a culture tank, a stirring shaft, a feeding tube and a discharging tube; a temperature sensor is arranged on one side of the upper part of the culture tank; an electric heating tube is arranged on one side of the middle of the culture tank;the stirring shaft is vertically arranged along the central axis of the culture tank and is driven to rotate through a motor; the stirring shaft is further provided with vertical stirring blades; a filter screen is arranged at the upper end of the feeding tube, the upper end of the feeding tube communicates with the lower part of the tank, and the lower end of the feeding tube communicates with the culture tank; and the upper end of the discharging tube communicates with the annular tube through a three-way valve, and the lower end of the discharging tube communicates with the bottom of the culture tank through a circulating pump. The anaerobic fermentation device has the advantages of high fermenting speed, high yield of methane and the like.

Description

technical field [0001] The invention relates to the field of fermentation equipment. More specifically, the present invention relates to an anaerobic fermentation device. Background technique [0002] Anaerobic fermentation refers to the stabilization of waste organic matter through microbial metabolic activities under anaerobic conditions, accompanied by changes in the production of methane and CO2. In the existing anaerobic fermentation process, the fermentation substrate will gradually degrade and form a scum layer, a supernatant layer, an active layer and a sediment layer, and the existence of the scum layer will seriously affect the fermentation efficiency and methane yield. Contents of the invention [0003] It is an object of the present invention to solve at least the above-mentioned problems and to provide at least the advantages which will be described later. [0004] Another object of the present invention is to provide an anaerobic fermentation device, which ...
