摘　　要：基于对丙烯高温氯化反应条件的研究,提出了该反应器放大的原则,确定了两种将反应器生产能力扩大至原来的1.7倍的放大方案:①反应器直径和高度都放大至原来的1.195倍,喷嘴截面积增加至1.7倍;②反应器直径放大至原来的1.306倍,高度不变,喷嘴截面积增加至1.7倍。利用计算流体力学(CFD)软件CFX5对这两种放大方案进行了模拟计算,对放大前后反应器出口氯气摩尔分率、出口温度、釜内最高温度、釜内平均温度、釜内温度和流场分布图等进行了对比分析,结果表明,高径比例不变的放大方案最好。Base on the research of reaction conditions on propylene chlorinated, the scale up principles of the reactor were brought forward. Two schemes that enlarging original reactor＇s capacity 1.7 times were ascertained, these schemes including： （1）enlarging both the diameter and the height of the rector to 1. 195 times and the nozzle＇s section to 1.7 times ;（2） keeping the height of the rector invariant and enlarging both the diameter of the rector to 1. 306 times and the section of the nozzle to 1.7 times. The scaling up characteristics of high temperature chlorinated propylene reactor was investigated with help of computational fluid dynamics （CFD） software CFXS. Comparing original reactor＇s outlet mole fraction of chlorine, outlet temperature, max temperature and average temperature of the reactor, the distributing figure of temperature and flow field for the reactor with the scaling up one, the results shows that the scheme that keeping the ratio of height to diameter invariant is the best.
