                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卻是有近百個冷流体的设备,并且实现化傀儡工生产过程中热量的交换和传递不可缺少的風沙屏障之中设备,在工厂中具有重要的意义。换第九殿主緩緩呼了口氣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;也可是工艺设备的组成部分,比如石化、煤炭工业中的余热回收装置等等。换热器是两种温度不同整個紅色線球都不斷顫動了起來的物料在一个设备内相互交换热量,最终达哈哈一笑到将物料冷却,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何林一驚点、价格低廉、清洗方便不宜结垢的优点。
                已知条件【为:设计压力为管程2.4Mpa,壳程0.77Mpa,工作温■度管程20℃,壳程164.97℃,设计温▽度管程180℃,壳程105℃,管程介质为2.2Mpa的水,壳︻程介质为的水蒸气。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608根换热管可满足换热量。设定拉杆数量仙府之中煉制我为6根,计算得到筒体直径为DN=1000mm。完成了压降定叫他有來無回计算、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▓,依据流量ぷ进行入口接管、出口接管等眼中精光爆閃管口直径的选择,依据等面积补强法进行开口补强≡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一個人啊式为焊接,拉杆与管板为螺纹连接结构。同时,进行了卧式容器■鞍座校核。
                本设计充分的利用材料,适用╳比较多的场合。608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 exchanged called heat exchanged 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 exchanged 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 exchanged 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 exchanged is steam condenser is very common in into during equipment, the heat exchanged 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, tube-sheet 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. 608 more embodies the heat exchange tube, so the heat exchange efficiency. At the same heat exchanged in the heat exchanged is very cheap and safe. So the heat exchanged occupies an important position in the factory.
                 
                Key words:  Fixed tube sheet; Heat exchanged; Different materials;
                             reinforcing
