摘要:设计是依据“云锡氯化法”处理难选贫锡矿，火法工序所得到的收尘沉淀，利用氯化钠溶液进行浸出，得到氯化铅和锡精矿。按照给定的工艺路线，及要求的年产量，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的物种数量，选择设备，并对主体设备——搅拌洗涤槽、冷却结晶设备进行设计，达到符合生产要求的目的。
设计主要是确定设备，进行车间的设备配置，满足生产要求。设计过程尽量采用新技术，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:The design is based on the" Yunnan tin chloride" processing refractory lean ore, pyrometallurgical process the dust precipitation, using sodium chloride solution leaching, get the lead chloride and tin concentrate. According to the given process, and requirements of the production process, calculated for each of the required amount, derived from the process of material balance and water balance, according to the calculated each process a number of species, selection of equipment, and the main equipment -- stirring washing tank, cooling crystallization equipment design, to meet production requirements to the purpose.
Design is the main equipment, workshop equipment, to meet production requirements. The design process as far as possible the use of new technologies, and strive to design more reasonable, convenient operation, as the workshop will obtain good economic benefits to lay the foundation.
Keywords: Design of dust precipitation; workshop
