摘　　要：以阴极锌铸型渣为原料,对水洗除氯工艺进行了系统的条件试验研究,并得出结论:在固液比1∶10、温度70℃、时间1.5 h、中等搅拌强度的条件下,氯的脱除率为84.64%。在此试验条件下,以阴极锌熔铸电炉烟尘、蒸馏炼锌焦结烟尘、挥发窑氧化锌多膛炉除氯烟尘为原料,进行了半工业试验,一次水洗脱氯率可达85%～92%,高于火法烟化工艺,也高于文献报道的湿法脱氯水平。After tested removing chlorine by washing from cathode zinc casting slag,the author drew a conclusion.Under these conditions of solid-to-liquid ratio 1∶10,temperature 70 ℃,time 1.5 hours and middle stirring intensity,the rate of removing chlorine is 84.64%.Under these conditions,the author carried out a pilot test using EAF dust of casting cathode zinc,coking dust of zinc distilling and removing chlorine dust from multiple hearth furnace of volatilization kiln zinc oxide as materials,the primary rate of removing chlorine can be reached to 85%～92%.The rate of removing chlorine from this process is better than fuming process and the other removing chlorine process on present references.
