模块化滚筒好氧发酵反应器设计与试验OA北大核心

Aiming at the problems of the existing drum-type aerobic fermentation reactor,such as the fixed volume of the cavity,high energy consumption in operation,and the difficulty in recycling the waste heat of tail gas,based on the mod-ular design concept,a modular drum-type aerobic fermentation reactor was developed,which is mainly composed of modules such as the drum,aeration system,waste heat recycling device,drive system,and sealing connectors.The composting performance test of the modular drum-type aerobic fermentation reactor was carried out.The results showed that the seed germination index reached more than 90%after the high temperature period lasted for 9 days and the fer-mentation lasted for 15 days,and all indicators met the requirements of compost maturity and harmless treatment.The design improves the processing and assembly efficiency of the drum aerobic fermentation reactor,expands the application scope of the drum aerobic fermentation reactor,and has the advantages of adjustable scale,segmented drive,staged fer-mentation,and accurate aeration,providing support for the development and application of the composting technology of the drum aerobic fermentation reactor.
