Abstract
A pretreatment system for biogas fermentation. The drive shaft drives the upper curved plate, the lower curved plate, the stirring rod, and the stirring hook to destroy and crush the straw to be treated in the main processing bin, so as to reduce the volume of the straw and increase the humidity of the straw. Excellent mixing uniformity, especially when the top of the upper spindle is connected to the clockwise drive motor, and the top of the lower spindle is connected to the counterclockwise drive motor, the clockwise and counterclockwise switching rotation can be interrupted during operation, and the heating device It can increase the temperature in the main processing chamber, and the temperature sensor can monitor the temperature in the processing main chamber to ensure the crushing effect. This design not only has a better crushing effect, but also can switch the crushing direction, which is beneficial to the subsequent fermentation, and can improve the filtration efficiency, with strong controllability and good environmental protection.
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...
