F360U型管式换热器设计
摘要
本次设计课题为F360U型管式换热器，管式换热器的组成部分有：壳体、管体和管子，管箱，折流板，接管，支座等零件和其他附件。本次设计的U型管换热器为单壳程双管程，将管体的两端均匀的固定在一个管板上，让管体可以自由的收缩，使它具有高的热补偿性和较低的热应力；此次设计中采用的是双管程，双管程的好处有，它的流动速比较快，其中流动过程变长，管程承受压力能力高，有较好的传热性；同时应为管体可以轻松取出，大大的降低了它的清洁和维修难度，使得它的制造成本变低。其中管的排列比较密集，在管的规格相同的情况下，它的生产制造也比较简单。在使用时管程受热为430℃，承受压力是1.2MPa，采用的介质是烟道气；使用时壳程受热为90℃，所受压力是1.15MPa,采用的介质是水；它的换热面积360㎡。
其中主要过程有主体的结构设计，材料的选择和零部件的设计，强度计算和校核，加工工艺等。换热器的设计需要注意：管体的排布形式及尺寸、圆筒、管板的材料选择和厚度加工以及防冲板等等。

ABSTRACT
The design of the use of dual-tube process, the advantages of the two-pipe process, it's faster flow,which the flow of the long process, the pressure towithstand high capacity, a better heat transfer and pipe, tube box, baffle plate, take over, support and other parts and other accessories. The design of the U-tube heat exchanger for the single shell double pipe, the pipe body at both ends of the uniform fixed on a tube board, so that the tube can be freely contracted, so that it has high heat compensation and low thermal stress, the pipe is used in two-pipe process, its advantages are, the flow rate is faster, the process is long, high pressure capacity, a better heat transfer; At the same time, the tube can be easily removed, greatly reducing the difficulty of its cleaning and maintenance, making it lower manufacturing costs. The arrangement of the pipe is more dense, in the case of the same specification, its production and manufacture is relatively simple. In use, the tube is heated to 430℃, the pressure is 1.2MPa, the medium used is flue gas,when the shell is heated to 90℃, the pressure is 1.15MPa, the medium used iswater, and its heat exchange area of 360 square meters. The main process has the main structure design, material selection and parts design, strength calculation and check, processing technology.
The design of heat exchanger needs attention: the arrangement form and size of the tube body, the material selection and thickness processing of the tube plate and the punching board etc.
Keywords: U-Tube heat exchanger, shell process, pipe process, medium structure design, parts
