摘要：本设计是依据“云锡氯化法”处理难选贫锡中矿，火法工序所得到的收尘沉淀，利用氯化钠溶液进行浸出，得到一定湿度的氯化铅和锡精矿。按照给定的工艺流程，设计中要求的年产量，计算出每个工序所需的量，推导出工艺流程的物料平衡和水系平衡，根据计算出的每个工序所需的量，选择辅助设备，并对主体设备——搅拌洗涤槽进行设计，目的在于保持母液温度下过滤，浸出液在不结晶，减少氯化铅进入浸出底流的量，降低洗涤负荷。
本设计主要是确定辅助设备的类型及型号，主体设备的设计，画出主体设备搅拌槽的工业设计图、工艺流程图和车间设备布置图，其中，车间布置与浆化洗涤槽的设计是本设计的重点与核心。为了适应我国现代锡工业的发展要求，同时本着节能和获得最大经济效益的原则，并考虑环境保护的因素，本设计尽量采用新技术，力求设计更加合理，方便操作，为车间今后取得良好的经济效益奠定基础。

ABSTRACT：This design is based on "YunXi LvHuaFa" deal with hard-to-beneficiate poor tin middlings gets, the dominated process to collect dust precipitation, using sodium chloride solution for leaching, get certain humidity of chlorinated lead and tin concentrates. According to a given process, design requirements, calculated the annual amount of needed for each working procedure is deduced, the material balance and process water balance, according to calculate the amount of each working procedure, needed to choose auxiliary equipment, and main equipment - stirring catharsis chamfer to carry on the design, the purpose is to keep liquor temperature filtration, leaching solution in not crystallization, reduce chlorinated lead into leaching of quantity, reduce the flow washing load.
This design is determining the type of auxiliary equipment and model number, the design of main equipment, draw the main equipment of industrial design drawings and stirring chest flow chart and workshop equipment layout, among them, the workshop of arrangement and the design of slurry catharsis chamfer is this the focal point of design and core. In order to adapt to the development of China's modern tin industry requirements, but also in line with energy-saving and obtain the biggest economic benefits, and the principle of environmental protection factor, this design try to adopt new technologies, and strive to design more reasonable, convenient operation, for workshop next good economic benefit is obtained lay the foundation.
