1、 本本 科科 毕毕 业业 设设 计计 ( (论论 文文) ) 蒸汽冷凝器蒸汽冷凝器设计设计 Design of Steam Condenser 毕业设计（论文）中文摘要毕业设计（论文）中文摘要 蒸汽冷凝器的设计 摘 要：冷凝器是使用范围很广的一种化工设备，属于换热器的一种。本设计任 务主要是根据已知条件选择采用浮头式换热器机的设计。 首先根据给出的设计温 度和设计压力来确定设备的结构形式以及壳程和管程的材料， 然后根据物料性质 和传热面积来确定换热管的材料，尺寸，根数。根据换热管的根数确定换热管的 排列，并根据换热管的排列和长度来确定筒体直径以及折流板的选择。通过对容 器的内径和内外压的计算来
2、确定壳体和封头的厚度并进行强度校核。 然后是对换 热器各部件的零部件的强度设计，有法兰的选择和设计计算与校核，钩圈及浮头 法兰的设计计算与校核和管子拉脱力的计算。 还包括管板的结构设计、 防冲挡板、 滑道结构的设计以及支座设计。 结构设计中的标准件可以参照国家标准根据设计 条件直接选取；非标准件，设计完结构后必须进行相应的应力校核。 关键词：换热器；强度设计；结构设计 毕业设计（论文）外文摘要毕业设计（论文）外文摘要 The Design of Steam Condenser Abstract: Condenser is a kind of chemical equipment which h
3、as wide range of application and it is also a kind of heat exchanger.The main task of this thesis is to design a floating heat exchanger based on some known information. It is important to determine the type of construction of the equipment and the material of its shell pass and tube pass first. The
4、n, the material, size and number of the exchange tube are decided by material property and its heat transfer area. The exchange tubes need to be arranged on the basis of its number. Whats more, the diameter and the choice of baffle board are influenced by the arrangement and length of exchange tubes
5、. Furthermore, the thickness of the shell and shell cover is determined by the inner diameter and the calculation of inner and outer pressure of the container. Meanwhile, its intensity also needed to be checked. Next, it is also vital to design the intensity of components of heat exchanger, includin
6、g the choice, calculation and checking of flange, floating flange and backing device, also the calculation of pulling-out force of the tubes. In addition, there are other things to be designed carefully, including tube plate, impingement baffle, slide and support. During the design of structure, standard components can be referred to national standards according to the design conditions of the direct selection; as to the non standard components, corresponding stress checking is needed after
