摘要
在锌的湿法冶炼过程中，氟氯的大量存在会造成阴、阳极板腐蚀严重，剥锌困难及析出锌含铅高，严重影响锌电解的正常作业。文章介绍了湖南某炼锌厂在氯的脱除方面进行的工艺研究与应用。通过多种方法——多点除氯工艺的实施，溶液氯含量由800～1000mg／L降至400～500mg／L。
In the process of wet zinc smelting, the abundant fluorine and chlorine will cause serious corrosion of the cathode and anode plate, and lead to strip zinc difficultly and also high precipitation lead in zinc, which seriously af- fect the normal operation of zinc electrolysis. In this paper, it introduces a chlorine removal technology research and application in a factory in Hunan province （China） about wet zinc smelting. Through a variety of methods-multipoint to the implementation of the chloride process, the solution of chlorine from 800 - 1 000 mg/L fell to 400 - 500 mg/L.
