摘　　要：为保证在内部流场压力和温差热应力双重作用下急冷塔的结构强度满足要求且安全可靠,需要对急冷塔的应力进行流固耦合仿真分析。首先采用ANSYS Fluent对急冷塔内部流场进行仿真模拟,获得急冷塔内部温度分布云图;其次采用ANSYS Mechanical对急冷塔进行结构强度计算。结果表明:塔内部中心烟气由上向下温度逐渐降低,存在明显的温度梯度;在温差热应力及流场强度作用下急冷塔最大应力强度为288.2 MPa,最大变形为5.8 mm。经过JB4732-2005标准判定,急冷塔和支腿组件均满足强度满足要求。In order to ensure the structural strength of quench tower under the dual action of internal flow field pressure and temperature difference thermal stress.It is necessary to analyze the internal stress of quench tower by fluid-structure coupling simulation.Firstly,ANSYS Fluent was used to simulate the internal flow field of quench tower,and the temperature distribution of quench tower was obtained.Secondly,ANSYS Mechanical was used to calculate the structural strength of quench tower.The results showed that the flue gas temperature in the center of the tower decreased gradually from top to bottom,and there was an obvious temperature gradient.Under the action of temperature difference thermal stress and flow field strength,the maximum stress strength of quench tower was 288.2 MPa and the maximum deformation was 5.8 mm.According to the JB4732-2005 standard,the quench tower and the leg assembly met the strength requirements.
