高温高压微波化学反应器耦合窗的应力分析

一些高温高压微波化学反应器使用圆形陶瓷片作为介质耦合窗口。本文基于有限元的方法,对窗口在不同腔体内压和微波输入功率下的热应力和机械应力分布进行了计算,并且进行了分析比较。结果表明:介质耦合窗上的热应力和机械应力及其形变随着腔体内压和输入功率的变化而发生很大改变,并且在不同条件下介质耦合窗上主要作用应力也不同。主要作用应力对高温高压微波化学反应器窗口的结构设计具有很高的参考价值。

Analysis of Stresses on Microwave Transmission Window for Microwave Chemical Reactor of High Temperature and High Pressure

Some microwave chemical reactors of high temperature and high pressure use circular ceramic as dielectric coupling window.In this paper,based on calculation of finite-element method(FEM),the distributions of thermal and mechanical stresses were computed with different pressures in the reactor and input microwave power,and these two stresses were analysed and compared.Simulations indicate that the distribution of thermal and mechanical stresses on the dielectric coupling window and the window' s deformation ...
