毕业设计说明书 年产0.9万吨CPE-H135生产工艺设计 专 业 高分子材料与工程 学生姓名 顾 小 云 班 级 Ｂ高分子012 学 号 0110220220 指导教师 何 显 运 完成日期 2005年６月 摘 要 氯化聚乙烯(CPE)是聚乙烯经氯化而制得的产品。介于其优良的性能和极好的相容性,且原料来源丰富,价格又相对较低,使得其市场需求量逐年增加。目前CPE的生产工艺主要有溶液法、水相法、固相法和酸相法，水相法工艺由于氯气利用率高，产品含氯量稳定，生产成本相对较低，所以在几种生产工艺里占主导地位。本设计主要介绍氯化聚乙烯（CPE）的水相悬浮法生产工艺流程。计算了物料衡算及氯化反应热量，并设计了配套的氯化反应釜及相关辅助设备；以及对CPE生产过程中产生的废气、废水、废渣的处理问题进行了考虑。另外，还包括生产工艺流程及氯化反应釜设计图纸。 关键词：水相悬浮法；氯化聚乙烯；生产工艺设计 Production Technology Design of CPE-H135 Annual 9000 Tons Abstract: The chlorine polyethylene (CPE) is prepared by chlorinating PE. It has good performance and excellent compatibility; its raw material resources are rich and raw material price is low, which makes its market demand increased year by year. The production technology of CPE has solution-state method, water-state method, solid-state method, and sour-state method at present. Water-state method plays a leading role because the chlorine utilization ratio is high; the chlorine content of the product is steady and the production cost is relatively low in China. This paper introduces production technology of CPE prepared by chlorinating PE suspended in water. The amount of input and output materials and quantity of chlorination reaction heat are calculated. Chlorination reaction kettle and its additional equipments are designed. Also exhaust gas, waste water and waste residue are taken into consideration. In addition, the paper includes production process and chlorination reaction kettle equipments drawing by hand and CAD.
