Abstract

The invention relates to a roller type composting reactor with composting tail gas waste heat recovery and purification functions. The roller type composting reactor includes a fermentation roller, anaeration system, a tail gas recovery system, a tail gas utilization system, a power system and monitoring system; the fermentation roller is installed on a base, and the feed end and discharge end ofthe fermentation roller are connected with a raw-material pretreatment system and a subsequent processing device respectively; the air discharge end of the aeration system is communicated with the inside of the fermentation roller through the feed end of the fermentation roller; the tail gas recovery system is communicated with the inside of the fermentation roller through the discharge end of the fermentation roller; the tail gas utilization system is used for recycling tail gas in the fermentation roller, the power system is installed on a base on the lower portion of the middle of the fermentation roller and used for providing power to operation of the fermentation roller; the monitoring system is connected with the fermentation roller, the aeration system, the tail gas recovery system, the tail gas utilization system and the power system through a communication network. The reactor can be widely used in the field of composting.

Description

technical field [0001] The invention relates to a composting reactor, in particular to a drum-type composting reactor with the functions of recovering and purifying waste heat of composting tail gas. Background technique [0002] Composting technology is one of the important means to realize the harmless treatment and resource utilization of livestock and poultry manure. It is in line with the development direction of agricultural green production and is an important measure to realize the cycle of agricultural planting and breeding. The existing livestock and poultry manure composting technologies mainly include three types: strip stacking, trough and reactor composting, among which the reactor composting device has the advantages of convenient operation, high processing efficiency, small footprint, and wide application range. more and more widely used. Among the reactor-type composting devices, the drum-type composting reactor has the advantages of continuous composting p...
