Pretreatment raw material multi-stage filtering system for biogas

Abstract

The invention relates to the technical field of biogas raw material pretreatment, and specifically relates to a pretreatment raw material multi-stage filtering system for biogas. The pretreatment rawmaterial multi-stage filtering system for biogas comprises a rack, a stirring box, a vibration filtering mechanism, a knockout machine, a fiber cleaning mechanism, a rotary driving mechanism, a fine sand sending mechanism, a discharging mechanism and a collecting mechanism, wherein the stirring box is installed on the rack; the vibration filtering mechanism is erected on the stirring box; the knockout machine is erected at the top end of the vibration filtering mechanism, and a discharging end of the knockout machine is in butt joint with a charging end of the vibration filtering mechanism; the fiber cleaning mechanism is arranged on the stirring box in a mode of stretching out of the stirring box in the horizontal direction; the rotary driving mechanism is rotatably arranged in a semicircular part of the stirring box; the fine sand sending mechanism is installed at one side of the semicircular part of the stirring box and horizontally faces a second blowdown port; a charging end of the discharging mechanism is installed on a first blowdown port of the stirring box; and the collecting mechanism is arranged at one side of the stirring box. According to the scheme, the pretreatment raw material multi-stage filtering system for biogas is good in filtering effect, long in service life, and high in control precision.

Description

technical field [0001] The invention relates to the technical field of pretreatment of biomass biogas raw materials, in particular to a multi-stage filtration system for pretreatment raw materials of biogas. Background technique [0002] The rapid development of the livestock and poultry breeding industry is accompanied by a large amount of animal manure and related waste. As a practical engineering system, biogas engineering is currently an important way to process raw materials such as livestock and poultry manure, improve the environment and utilize biomass energy. way. [0003] The transmission of materials in biogas projects is mainly realized by the delivery pump, but during the transmission process, the agglomeration of raw materials and fibrous objects often cause blockage problems for pumps, valves, external and central control equipment. [0004] The biogas raw material has high sand content and a small amount of feathers. For biogas projects that use livestock an...
