                设计简介
                摘要
                    换热器又被叫热量交换器,是一种把热流体的热量传递给冷流体的设备,并且实现化工生产过程中热量的交换和传递不可缺少的设备,在工厂中具有重要的意义。换热◢器可以是一种单独的设备,例如加热器、冷却器和凝汽器等等。换热器是两种温度不同的物料∮在一个设备内相互交换热量,最终达到将物料冷却,或者将冷物料加热为目的的◢设备。本换热器是蒸汽冷凝器在成产中是非常常见╱的设备,该换热器有耐高压的优点、价格低廉、清洗方便不宜结垢的优点。
                已知条看着黑蛇件为:设计压力为管程1.3Mpa,壳程0.9Mpa,工作温度管程25℃,壳程164.97℃,设计温度管程75℃,壳程85℃,管程介质▽为1.3Mpa的水,壳程介质↘为0.9Mpa的水蒸气。依据给定条件所得传〓热面积为241.6m2。考虑到介质特性等因素,采用Φ25×2.5×4500的#20(材料)的无▲缝钢管,本设计◣采用根换热管可满足换热量。设↑定拉杆数量为6根,计算得到筒体直径为DN=1000mm。完成了压降计算々、强度计算、开孔补强、管箱短节壁※厚计算等。在强度设计中,依据GB150进行筒体、封头强度设计☆及校核,依据流量进行入口接管、出口接管等管口◆直径的选择,依据等面积补强法进行开 笑着点了点头口补强计算。本设计选择管板延长兼做法兰,依据GB151中的弹性支⌒撑假设对管板进行设计和校核,管板与换热管的连接方式为焊接,拉杆与管板为螺纹连接结√构。同时,进行了卧恶魔之主式容器鞍座校核。
                    本设计充分的利用材★料,适用比较多的场合。366根换热管更加体现了换热的效率。在同样的换热器中此换热器十分的廉价、安全。所以该换热器在工厂中占有重要位置。

                Abstract
                Heat exchanger called heat exchanger again, it is a kind of the thermal fluid heat transfer to cold fluid equipment, and realize the heat exchange and transmission in the process of chemical production indispensable equipment, has the vital significance in the factory. Heat exchanger can be a single device, such as a heater, cooler and steam condenser, etc. But also part of the process equipment, such as waste heat recovery unit in petrochemical industry, coal industry, and so on. Temperature heat exchanger are two different materials in a heat exchanging equipment, eventually achieve the material cooling, or heating equipment for the purpose of cold material. This heat exchanger is steam condenser is very common in into during equipment, the heat exchanger has the advantages of resistance to high pressure, low cost, convenient cleaning is unfavorable and scale advantages.
                Known condition is: the design pressure for tube side and shell side, working temperature tube side and shell side, the design temperature tube side and shell side, the medium as the water passes, shell side medium is water vapor. Based on the heat transfer area of the given conditions. Considering the characteristic of medium etc factors, using (material) seamless steel tube, this design USES the root heat exchange tube can meet the change of heat. Set rod of 6 root number, calculate the cylinder diameter. Completed the pressure drop calculation, strength calculation, opening reinforcement, short tube box section wall thickness calculation, etc. In strength design, strength design basis for cylinder, head and checking, according to the inlet connection of traffic and exports over the selection of nozzle diameter, opening reinforcement method on the basis of equal area reinforcement calculation. The design of flange, tubesheet extended and do according to the hypothesis of elastic support for tube plate design and checking, tube plate and the heat exchange tube connections for welding, rod and tube plate to the threaded connection structure. At the same time, for the horizontal vessel saddle checking.
                This design make full use of material, is more occasions. 366 more embodies the heat exchange tube, so the heat exchange efficiency. At the same heat exchanger in the heat exchanger is very cheap and safe. So the heat exchanger occupies an important position in the factory.
                Key words:   Fixed tube sheet; Heat exchanger; Different materials;
                             reinforcing
