固定管板式换热器的设计学生：库勇智，化学与环境工程学院指导老师：王小雨，江汉大学摘 要 换热器是用来在流体间交换热量的装置，在化学专业中具有非常重要的地位，被使用于化工各行业中。由于其中固定管板式换热器管板和壳体是一体构造，具有结构简单、造价十分便宜的优点，所以被普遍的使用。 这篇设计说明书上面着重说明了换热器的换热面积、各个设计压力和设计温度以及接管等数据参数。根据上面所给的数据和换热器类型来对换热器的各个零部件，即换热管根数，尺寸、排列方式，壳体和管箱、封头等等，最后校核、压力试验，根据工艺结构选出材料，最后作图。 本设计说明书的每一部分都是完全参照 GB150-2025《压力容器》和 GB151-2025《热交换器》中固定管板式换热器的有关标准来计算、校核和选型的。关键词管壳式换热器 ；固定管板式换热器 ；加热器AbstractHeat exchanger is a device for exchanging heat between the fluids and in chemistry has a very important position, is used in the chemical industry. Because of the fixed tube plate heat exchanger tube plate and the shell is an integral structure, with has the advantages of simple structure, low cost advantages, so be widely use.The design specification above illustrates the change of the heat exchange area of the heat exchanger, each design pressure and temperature and over data parameters. According to the data given above and the heat exchanger type heat exchanger parts, i.e. the heat exchange tube number, size, arrangement, shell and tube box, head, and so on, finally checking, pressure test, selected according to process structure materials. Finally, drawing.The design specification is strictly according to GB150-2025< pressure container > and heat GB151-2025< exchanger is > fixed tube plate heat exchanger of the relevant provisions of the calculation, selection and checking.Key wordsShell and tube heat exchanger ；fixed tube heat exchanger ；heater 目 录摘 要-------------------------------------...
