摘　　要：基于ASPEN PLUS模拟平台,对机械脱水后含水率为70%的污泥经热干燥后再进入循环流化床焚烧的模拟计算,与其他焚烧过程计算方法相比,可以快速实现污泥焚烧过程的模拟,并可方便对焚烧工艺及物流参数进行优化调整。结果显示:完全可用污泥焚烧后的烟气对污泥进行干燥;用污泥焚烧后的烟气(300～400℃)对污泥进行干燥,可将污泥含水率由70%降至60%左右,而不需要额外的热源;随着污泥含水率由70%降低到60%,污泥的发电效率不断增加。Based on the ASPEN PLUS simulation platform,drying and fluidized bed incineration process of mechanically dewatered sludge with 70% moisture content was simulated.Compared with other calculation methods,this method could achieve sludge incineration simulation rapidly,and could further optimize the technology or adjust the stream parameter conveniently.The obtained results showed that the heat of flue gas（about 300 ~ 400 ℃） could be used to dry the initial sludge,and the moisture content of sludge could be reduced to 60% without additional energy and the generation efficiency increased with the decrease of moisture content from 70% to 60%.
