摘要
介绍了DN5200/4900 mm丁醛转化器有限元应力分析计算方法,该反应换热设备直径大,远超出GB 151中的DN2600 mm,设计压力较小,结构重力、介质重力和管、壳程流阻压力降等影响不可忽略。88.9 mm×3.20 mm的换热管,弯曲刚度较大,对按梁和杆模拟换热管分析结果进行比较。为超大型换热设备的设计计算提供参考。
The finite element stress duced. The diameter of the heat exc analysis of one DN5200/4900 mm butyraldehyde converter was introhanger low design pressure, the structure gravity, is very large, far beyond DN2600 mm in GB 151. Because of medium gravity, tube and shell pressure drop arise from fluid resistance can not be ignored. The heat exchanger tube, Φ88.9 mm×3.20 mm, has large bending stiffness, so the simulated analysis results were compared as beam and link element. It provide reference for the design and calculation of super large heat exchanger.
