摘要
Abstract
During the trial operation of the isocyanate and polyether MMDI distillation column,the dividing wall is distorted,so that the distillation can not work on. Finite element method is used in this subject, considering the dividing wall with no flaw, out -of-flatness and with initial stress,the deformation during the temperature loading is studied,unloading and re - loading respectively. According to the results, main factors for deformation of dividing wall are analyzed and possible solutions are proposed eventually.关键词
