摘　　要：2007年,攀钢海绵钛分公司全套引进乌克兰熔盐氯化法生产海绵钛的技术,现已建成并投入生产,经过连续攻关,全厂工艺流程已全部打通。通过对熔盐氯化过程中产生的尾气成分,以及传统二级水洗四级碱洗工艺处理原理的分析,结合攀钢生产实际,对尾气处理系统进行优化,采用三级水洗三级碱洗工艺对熔盐氯化尾气进行处理,能有效避免堵塞并减少碱液的使用,处理后的尾气能达标排放,洗涤废液可用于下游生产。In 2007,Panzhihua Iron and Steel Sponge Titanium Branch introduced a full set of Ukrainian molten salt chlorination technology to produce sponge titanium.It has been completed and put into production.After continuous research,the entire plant’s process flow has been fully opened up.Through the analysis of the exhaust gas composition generated during the molten salt chlorination process and the treatment principle of the traditional two-stage water washing and four-stage alkaline washing process,combined with the actual production of Panzhihua Iron and Steel,the exhaust gas treatment system is optimized,and the three-stage water washing and three-stage alkaline washing process is adopted.The treatment of molten salt chlorination tail gas can effectively avoid clogging and reduce the use of lye.After treatment,the tail gas can be discharged up to the standard,and the washing waste liquid can be used for downstream production.
