四合一重整反应器应力分析和结构优化

STRESS ANALYSIS AND CONSTRUCTION OPTIMIZATION OF CCR REACTORS OF"FOUR IN ONE"DESIGN

连续重整装置四合一反应器承受高温、内压及压力降、自重、风、地震等载荷作用,其裙座部位的应力数值很大、分布复杂,因此裙座结构是该设备的设计关键。通过调整四合一反应器裙座部位不同的结构型式,采用有限元方法对该部位在高温等6种载荷工况作用下的26个结构模型进行了计算和分析,从而确定了较为优化的结构设计方案,并提出了设计时需要考虑的要点。

As CCR reactors of ＂Four in One＂ design are subject to high temperature, internal pressure and pressure drop, equipment weight, wind load and seismic load etc, the skirt location has a very large comphcated stress distribution. Therefore, the correct design of skirt construction is very critical for the reactor equipment. Through the adjustment of different skirt constructions for the reactor and calculation and analysis of 26 models of skirt location under 6 different loads like high temperature etc by finite element method, the optimized construction was determined. Unique concepts and considerations in skirt design were presented.
