Abstract

The invention discloses a wet-type anaerobic marsh gas preparation device for kitchen waste and belongs to the field of anaerobic digestion tanks. The wet-type anaerobic marsh gas preparation device comprises a fermentation tank body, a material evenly-distributing system, a uniform discharging system, a stirring and residue breaking system, a heat balance system, a sand and residue draining system and a marsh gas collecting system. By means of cooperation of the systems, an anaerobic digestion tank resists impact loads; dross, crusting and blockage are not prone to occurrence, gas overflows smoothly, and no sand is accumulated on the bottom of the fermentation tank body; materials and temperature in the fermentation tank body are distributed evenly; the marsh gas generation efficiency is high, and overhauling and maintaining are convenient.

Description

technical field [0001] The invention relates to a device for wet anaerobic biogas production from kitchen waste, belonging to the field of anaerobic digestion tanks. Background technique [0002] At present, domestic and foreign food waste treatment processes mainly include landfill, incineration, anaerobic fermentation, aerobic composting, direct drying to make feed, pyrolysis and microbial treatment technologies. Compared with other treatment technologies, the anaerobic fermentation treatment technology of food waste is mature, the equipment is reliable, the input-output ratio is the best, it can adapt to the characteristics of food waste, meet the requirements of environmental protection, and meet the principles of circular economy and the requirements of energy saving and emission reduction in my country . [0003] Although anaerobic fermentation biogas has the above advantages, making it a mainstream process for kitchen treatment, but the practice in many regions in Chi...
