摘要：聚丙烯是由丙烯聚合而制得的一种热塑性树脂。按甲基排列位置分为等规聚丙烯、无规聚丙烯和间规聚丙烯三种。聚丙烯为无毒、无臭、无的乳白色高结晶的聚合物，密度只有0.90-0.91g/cm3，是目前所有塑料中最轻的品种之一。首先，介绍聚丙烯及聚丙烯聚合釜的一些发展概况、检验、安装、试车操作、岗位安全等内容。其次，根据所给工作压力和工作容积进行釜体的结构设计，选择釜体、夹套的材料，计算出釜体的工艺尺寸及夹套的工艺尺寸，筒体、封头壁厚的计算，夹套、封头壁厚的计算，并且进行内、外压校核以及水压试验校核，根据釜体开孔情况进行釜体、夹套的开孔补强计算，最终确定筒体、夹套的材料、内径、壁厚、高度。传动装置的计算，包括电动机、减速机、联轴器、搅拌轴（传动轴）、机架、安装底盖及凸缘法兰等的选择和计算。密封方式的选择及其他部件包括人孔、视镜、支撑结构等的选择和计算。33260

Design of the polypropylene Polymerization kettle
Abstract：Polypropylene is made up of propylene polymerization and obtained a thermoplastic resin. Sorted by methyl position is pided into isotactic polypropylene, atactic polypropylene and three kinds of syndiotactic polypropylene. Polypropylene is non-toxic, odourless, tasteless ivory high crystallization of polymer, only 0.90 -0.91 g/cm3 density, is currently one of the lightest of all plastic varieties. First of all, introduces some development situation of polypropylene and polypropylene polymerizer, inspection, installation, commissioning operation, job security, etc. Secondly, according to the working pressure and volume given in body structure design, selection, jacketed kettle body materials, calculate the process dimension and jacketed kettle body size, the technology of cylinder wall thickness calculation, head, jacket, head the calculation of wall thickness, and carries on the internal and external pressure and water pressure test respectively, according to the situation of the kettle body opening and jacketed kettle body opening reinforcement calculation, finally determine the barrel, the material of the jacket, inner diameter, wall thickness, height. The calculation of transmission device, including motor, reducer, coupling, stirring shaft (shaft), frame, install the bottom cover and the selection and calculation of the flange flange, etc. The choice of the ways of sealing and other components including the manhole, sight glasses, selection and calculation of the supporting structure, etc.
