| 摘 要： | 针对我国目前对于大型脱硝反应器的设计无规范可循的状况,利用数值方法分析脱硝反应器结构,得到反应器整体变形与应力分布情况,以及反应器结构设计时应注意的构件与位置. 通过对比大、小变形时加劲板的应力与变形发现,考虑大变形影响后其应力值水平有所缓和,分布较均匀. 研究表明,在保证安全和满足反应器使用功能前提下,反应器的合理化设计尚有一定的空间.

| Abstract: | At present there is no design standard in designing large steel SCR (selective catalytic reduction) reactors. According to numerical analysis on the structure of a steel SCR reactor,the stress and deformation as well as weak position of whole construction are obtained. The results derived from geometric linear analysis and geometric nonlinear analysis are compared. According to the results,the data based on geometric linear analysis are conservative,and the stress distribution is more homogeneous when large... |
