摘要
为保证气液分离效率且合理地设计塔的强度,利用ANSYS软件建立设备筒体与切向接管的几何模型,获得了常用矩形截面和优化结构(长圆形截面、圆角矩形截面)接管的应力分布图.分析了接管形状和筋板设置对切向接管处应力的影响,结果表明:圆角矩形截面接管在更好地满足分离效率的情况下,能够减少筒体与接管处应力集中的现象,使切向接管处的应力分布更加均匀.同时,将圆角矩形截面接管按分析设计标准进行应力强度评定,其计算结果满足工程设计强度要求.
Abstract
For purpose of ensuring efficiency of air-liquid separation and designing tower strength reason-ably,ANSYS software was used to establish geometric model of the cylinder and tangential nozzle of the device,and the stress distribution of common rectangular section and the optimized structure(oblong sec-tion,rounded rectangular section)was obtained and influence of the nozzle shape and the ribbed plate set-ting on the stress was analyzed.The results show that,under the condition of better satisfying separation requirements,the stress concentration between the cylinder and the pipe with the rounded rectangular sec-tion can be largely reduced and the stress distribution at the tangential opening becomes more uniform.Meanwhile,assessing stress strength of the rounded rectangular section according to the analysis and design standard indicates that the results meet the requirements specified in the standard.
