Biogas fermentation pretreatment system

Abstract

The invention discloses a biogas fermentation pretreatment system. The biogas fermentation pretreatment system has the advantages that an upper bent plate, a lower bent plate, stirring rods and stirring hooks can be driven by a driving shaft to destroy and smash to-be-treated straw in a main treatment bin, so that the volume of the straw can be reduced, and the straw and moisture mixing uniformitycan be improved; particularly, clockwise and anticlockwise switching rotation can be intermittently carried out during operation when the top of an upper spindle is connected with a clockwise drivingmotor and the top of a lower spindle is connected with an anticlockwise motor, the internal temperature of the main treatment bin can be increased by a heating device and can be monitored by a temperature measuring sensor, and accordingly smashing effects can be guaranteed; the good smashing effects can be realized by the biogas fermentation pretreatment system, the smashing directions can be switched over, and accordingly the biogas fermentation pretreatment system is favorable for follow-up fermentation; the filter efficiency can be improved, and the biogas fermentation pretreatment systemis high in controllability and excellent in environmental friendliness.

Description

technical field [0001] The invention relates to a biogas fermentation system, which belongs to the field of environmental protection, in particular to a pretreatment system for biogas fermentation, which is particularly suitable for improving the crushing effect and facilitating subsequent fermentation. Background technique [0002] Biogas fermentation, also known as anaerobic digestion or anaerobic fermentation, refers to organic matter, such as human, livestock and poultry manure, straw, weeds, rice husk, wheat husk, bean husk, etc. The process of catabolism and the final formation of flammable mixed gases such as methane and carbon monoxide, which is biogas. Since most of its raw materials come from straws of crops such as wheat, corn, peanuts, and soybeans, as well as the shells of wheat, rice, peanuts, melon seeds, and beans, it is regarded as a highly environmentally friendly waste utilization method. [0003] The authorized announcement number is CN205954001U, and th...
