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。
Based on the study of the reaction conditions of high temperature chlorination of propylene, the principle of amplification of the reactor was proposed, and two amplification schemes were designed to expand the production capacity of the reactor up to 1.7 times: (1) Both the diameter and the height of the reactor were enlarged to the original 1.195 times, nozzle cross-sectional area increased to 1.7 times; ② reactor diameter enlarged to 1.306 times the original height unchanged, the nozzle cross-sectional area increased to 1.7 times. The CFX5 software CFX5 was used to simulate the two amplification schemes. The molar ratio of chlorine to the reactor before and after amplification, the outlet temperature, the maximum temperature in the autoclave, the average temperature in the autoclave, the temperature in the autoclave and the flow field Distribution and other comparative analysis conducted, the results show that the proportion of high-diameter amplification plan is the best.
