吸收塔是化工环保领域的重要设备,其底部槽钢结构能很好地保证吸收塔的静强度和抗震性能要求。利用ANSYS软件建立了吸收塔及其底部槽钢结构的有限元模型,完成了其结构静强度分析,得到了底板和槽钢结构的应力与位移分布规律,并进行了刚度和强度校核。计算结果表明,吸收塔底部平板外圆周和槽钢焊接处的变形和应力比其他位置要大,最大位移为0.15 mm,最大Mises应力为146 MPa,超过设计温度下Q235-B材料的许用应力值113 MPa,焊接位置发生断裂或拉伤的可能性较大,仿真结果与试验结果吻合较好。

Absorber tower is one of the important equipments in the fields of chemical and environmental protec-tion,and its bottom channel structure can guarantee the requirements of static strength and seismic performance of absorber tower. In this paper,the finite element model of absorber tower and its bottom channel structure was estab-lished by using ANSYS software,and its structural static strength analysis was performed. The distribution rule of stress and displacement for the bottom plate and channel structure was obtained,and the stiffness and strength check was finished. The results show that the deformation and stress at the weld location between the outer circum-ference of bottom plate and channel structure is larger than those at other locations,the maximum displacement is 0. 15 mm,the maximum Mises stress is 146 MPa,and it exceeds the allowable stress value 113 MPa of Q235-B un-der the design temperature. The weld location between the outer circumference of bottom plate and the channel structure has a large likelihood of fracture or injury,and the finite element simulation results match the experimen-tal results well.
