Three-dimensional liquid-phase fermentation helical stirring device

Abstract

The invention relates to a three-dimensional liquid-phase fermentation helical stirring device, which belongs to the methane fermentation technology. A biogass slurry horizontal anticlockwise helical conveying main pipe, a biogass slurry horizontal clockwise helical conveying main pipe and a biogass slurry annular vertical conveying main pipe are installed in a fermentation reaction tank body, wherein the biogass slurry annular conveying main pipe is arranged on the bottom side part of the fermentation reaction tank body, a biogass slurry horizontal anticlockwise ejection pipe is installed on the inner side part of the biogass slurry horizontal anticlockwise helical conveying main pipe, a biogass slurry horizontal clockwise ejection pipe is installed on the inner side part of the biogass slurry horizontal clockwise helical conveying main pipe, and a biogass slurry vertical ejection pipe is installed on the biogass slurry annular vertical conveying main pipe. The three-dimensional liquid-phase fermentation helical stirring device is simple and reasonable in structure, uniform in stirring and high in gas yield.

Description

technical field [0001] The invention belongs to biogas fermentation technology, and mainly relates to a spiral stirring device used for three-dimensional liquid-phase biogas fermentation. Background technique [0002] In biogas production, the stirring operation of fermented organic materials in the fermentation reaction tank can make the fermentation temperature equal, so that the organic fermented materials can be fully decomposed and produce corresponding digested gas, so the biogas production can be increased. At present, the stirring operation of organic fermentation materials through biogas slurry input in the fermentation reaction tank is one of the commonly used stirring methods at present. However, due to structural design defects, when the existing biogas slurry is input into the fermentation reaction tank, the injection direction of the biogas slurry is consistent, and the stirring ability and effect on the fermented organic matter in the fermentation reaction tan...

AI Technical Summary

Problems solved by technology

However, due to structural design defects, when the existing biogas slurry is input into the fermentation reaction tank, the injection direction of the biogas slurry is consistent, and the stirring ability and effect on the fermented organic matter in the fermentation reaction tank are relatively poor, especially The organic fermentation materials deposited at the bottom of the fermentation reaction tank are difficult to be stirred, and the biogas production needs to be improved
