摘　　要：对蓄电池用高密度聚乙烯(PE)隔板生产制程排放废气中的三氯乙烯(TCE),进行了溶剂回收以及排放控制的工艺研究。可再生活性炭吸附是一种高效的TCE回收与排放控制技术。通过对活性炭的选择,对制程废气温度、湿度的控制,以及对活性炭的再生工艺参数优化,TCE回收效率可达98%以上,回收的TCE溶剂可以直接回用于制程,降低了生产成本。经活性炭吸附处理的气体中,TCE浓度可控制在20mg/m;以下,满足环保排放要求。The process of solvent recovery and emission control of trichloroethylene (TCE) in waste gas from the production process of high density polyethylene (PE) separator for battery was studied.Renewable activated carbon adsorption is an efficient TCE recovery and emission control technology.Through the selection of activated carbon,the control of process waste gas temperature and humidity,and the optimization of activated carbon regeneration process parameters,the TCE recovery efficiency can reach more than 98%,and the recovered TCE solvent can be directly reused in the process,reducing the production cost.In the gas treated by activated carbon adsorption,the TCE concentration can be controlled below 20mg/m;,which meets the requirements of environmental emission.
