摘　　要：湿式电除尘器(WESP)的框架结构外部设有板筋结构以形成烟气通道。在采用有限元软件进行分析时,设置板筋结构后能够充分考虑板对整体结构刚度的贡献,从而实现更合理的设计优化。然而,常见的有限元软件不提供板的相关规范校核,因此需要进一步验证计算结果的可靠性。通过对比理论静力计算和有限元软件计算结果,探讨WESP结构的设计方法。结果表明:对组合截面进行合理假设后,静力计算结果与有限元计算结果吻合,这为有限元设计应用提供了有效的补充和验证。The frame structure of the wet electrostatic precipitator(WESP)is equipped with a plate reinforcement structure on the outside to form a flue gas channel.When using finite element software for analysis,the setting of the plate reinforcement structure can fully consider the contribution of the plate to the overall structural stiffness,thereby achieving more reasonable design optimization.However,common finite element software does not provide specification verification for plates,so it is necessary to further verify the reliability of the calculation results.By comparing the results of theoretical static calculation and finite element software calculation,the design method of the WESP structure was discussed.Results show that,after making reasonable assumptions about the combined section,the static calculation results coincide with the finite element calculation results,which provides an effective supplement and verification for the application of finite element design.
