浮头式换热器的设计 摘 要 本设计说明书是关于浮头式换热器的设计，主要是进行了换热器的工艺计算、换热器的结构和强度设计。 换热器是化工、炼油、动力、食品、轻工、原子能、制药、机械及其它许多工业部门广泛使用的一种通用设备。近二三十年来，化工、石油、轻工等过程工业得到了迅猛发展。因此，要求提供尺寸小，重量轻、换热能力大的换热设备。Floating Head Heat Exchanger Design Abstract This design manual is about the floating head heat exchanger design, mainly for the heat exchanger process calculation, heat exchanger design of the structure and strength. Heat exchanger is the chemical, oil refining, power, food, light industry, atomic energy, pharmaceutical, machinery, and other widely used in many industrial sectors as a general-purpose device. The past 23 years, chemical, petroleum, light industry and other process industries have been developing rapidly. Therefore, the required small size, light weight, large capacity heat exchanger heat transfer equipment. In the design process, I try to use a relatively new national standard, so not only meet the design requirements, but also to structural optimization, cost reduction, mainly to improve economic efficiency, and strive to make the products meet the actual needs of production for the market competition. Meanwhile, in order to make this design smoothly carried out, I read a lot before in the design of the books and English literature, and to do a certain amount of foreign language translation work The first part of the design is mainly the principle of heat exchanger, a detailed description of the structure, which for heat exchanger selection, structure design. The latter part is about the design of the structure and strength of the special heat exchanger, which is mainly to design the parts, such as tube-sheet, baffle plate, distance control, floating cover, tube boxes and so on , based on the heat exchanger types selected. The paper include: design and calculation, material selection, determining the specific dimensions , determining the exact location, pipe thickness calculation, the floating head cover and floating head flange thickness calculation, the opening reinforcement calculat
