摘　　要：分析某变换反应器裙座处隔热圈设置与其对应力的影响。计算结果表明,设置隔热圈时裙座处金属温度相对较高,但是温度梯度较小,对于消除裙座热应力作用明显。设置隔热圈时最大总应力是不设置隔热圈时的50%。塔式容器裙座设计时,壳体和裙座连接处要避开最大应力部位。This paper analyzed the impact of insulation ring,whether installed on the shift reactor skirt or not,on the stress.The calculation results showed that the metal temperature at the skirt was relatively high when the insulation ring was installed,but the temperature gradient was small.It had an obvious function for eliminating the thermal stress of the skirt.The maximum total stress with the insulation ring was 50%of that without the insulation ring.When designing tower container skirt,the joint between shell and skirt should avoid the maximum stress part.

关 键 词：塔式容器 裙座 隔热圈 热应力
