ABSTRACT：This design mainly discusses around dregs of As and Fe, dregs of Bi, dregs of Zn are the intermediates of disposing of high temperature chlorinate collecting solution in Sn. To collect the valuable metals, using the technology procedures: to prepare neutralizing—ferric salt and dearsenification—to neutralize and deposit Bi—to deposit Zn—to recover the watery CaCl2 to be underway. The design specification makes a detailed description of the process, which includes the calculations of Material balance, the selection of major equipments, the design of main equipment and the design of shop configuration.

Keywords: Chlorinate Collecting Solution; Valuable Metals; Design

在本次设计中，首先根据工艺流程及设计规模对砷、铋、锌、氯元素做平衡计算。其次，根据元素的平衡计算进行设备的选择和主体设备的设计，在此基础上完成了车间设备的平面布置。最后，应用AutoCAD软件完成了工艺流程图、设备连接图、设备配置图、主体设备总图的绘制，并完成设计说明说的编写。
