摘　　要：结合海绵钛生产工艺过程中氯化尾气的排放及治理现状,提出了采用菱锰矿吸收氯化尾气的工艺方案,通过热力学和动力学分析,表明该工艺是可行的。在单因素试验的基础上设计了三因素三水平的正交试验,结果表明:在氯离子初始浓度为90g/L,初始吸收温度为60℃,液固比为8∶1的条件下,氯化尾气的吸收率为98.76%,锰回收率可达95.23%。不仅能实现氯化尾气的无害化排放,而且试验制备的氯化锰品质较好。In this paper, combining with the chlorination exhaust emission and management present situation in the production process of titanium sponge, a process scheme is proposed,which rhodochrosite is used to absorb chlorination exhausts. Through the thermodynamics and dynamics analysis, the results show that the technology is feasible. On the basis of single factor experiment, three factors of the three level orthogonal experiment is designed, the results show that the absorption rate of chlorination exhaust is 98.76% and manganese recovery is 95.23% under the initial concentration of chloride ion for 90g/ L,initial temperature 60~C and the liquid - solid ratio for 8： 1, this technology is not only able to realize harmless chlorination exhausts emission and can prepare high -quality manganese chloride.
