Marginal effect disturbance elimination system of large straw biogas project

Abstract

The invention relates to the technical field of biogas engineering facilities, and provides a marginal effect disturbance elimination system for a large straw biogas engineering in order to solve a series of technical problems that materials in an existing fermentation tank float to form crusts and hinder gas production, the marginal effect disturbance elimination system is provided with a transverse compensator, and the transverse compensator is installed on a stirring shaft; the transverse compensator is used for breaking shells of floating biogas residues; the transverse compensator comprises a stirring arm and stirring teeth, the stirring arm is mounted on the stirring shaft, and the stirring teeth are mounted on the stirring arm. Through the transverse compensator, upper-layer scum can be stirred and hulled, the problems of scum and crusting in a straw biogas project are solved, stirring is more uniform, homogenization is achieved, fermentation materials and microorganisms make full contact, the maximum temperature difference between the upper portion, the middle portion and the lower portion does not exceed 2 DEG C, fermentation is promoted, the gas production potential of the materials is fully exerted, and the production efficiency is improved. Meanwhile, due to reduction of crusts and scum, material feeding is smoother, and the problem that the tank capacity is reduced is solved.

Description

technical field [0001] The invention relates to the technical field of biogas engineering facilities, in particular to a marginal effect disturbance elimination system for large-scale straw biogas engineering. Background technique [0002] At present, as the country gradually pays attention to the harmless and resource utilization of agricultural and forestry waste (straw, livestock and poultry manure, etc.), the biogas anaerobic fermentation project has ushered in a period of rapid development. During the operation of a biogas project, material stirring is an important factor affecting the fermentation of the fermentation system. Stirring is mainly to mix materials through the stirring system. Stirring can make the fermentation materials and microorganisms in a completely mixed state, increase the contact area between raw materials and microorganisms, and promote The aerobic fermentation process, the stirring system is the core system of anaerobic fermentation, especially i...
