锌浮渣干湿法处理工艺对比与干法处理工艺关键设备选型及应用

Comparison of dry and wet treatment process of zinc ash and selection of key equipment and application of dry treatment process

在湿法炼锌的工业生产中,电解阴极锌片在熔锌感应电炉内熔化除杂时产出副产品锌浮渣,锌浮渣中含锌约80%,其中70%以上锌以单质形态存在。本文对比了干法和湿法两种处理工艺的优缺点,重点介绍了干法处理工艺中关键设备选择和能力计算,并结合实际生产情况对投产后的工艺设备进行改进和完善。

In the industrial production of zinc hydrometallurgy,zinc ash is the by-product of electrolytic cathode zinc sheet melting and impurity removal in zinc melting induction furnace.Zinc ash contains about 80%zinc,of which more than 70%zinc exists in elemental form.In this paper,the advantages and disadvantages of dry and wet treatment processes are compared,the key equipment selection and capacity calculation for the dry treatment process are mainly introduced,and combined with the actual production situation the process equipment is improved and perfected after production.
