摘　　要：在湿法冶锌工艺中氯离子的浓度严重影响着冶锌工艺,目前市场上采用的除氯法效果不是很好。本文探讨了以新的离子交换树脂除氯法为基础,采用FPGA为控制核心进行在线检测与实时控制,以应用较为广泛的CAN总线作为通讯模式,解决了工业除氯效果不佳故障率低。Zinc metallurgy has seriously affacted by chloride concentration.In zinc hydrometallurgy,the chloride ion in zinc sulfate solution has becoming a vital problem. Nowadays silver sulfate sedimentation and Copper--catalyzed dechlorination are adopted by every factory,but they are not quite efficient. The article discusses a new type of removing chlorite ion by ion--exchange resins,which improved the grade of zinc and the exchange rate of resins,solved the inefficiency and controlling delay by using FPGA for on- line detection and real--time control,and by adopting large--scale industrial automatic control mode based on the CAN bus communication. This control system is characterized by its stableness,easy maintaining, and low failure rate.
