                设计简介
                摘要
                换热设备在工业生产中的主要作用是能够使热量从温度比较高的流体传递到温度炉鼎之内比较低的流体,从而使流体的温度达到工艺过程中规定的指标,满足工艺过程的需要。换热器中的管壳式换热器是目前应用最为广泛的一种换热设备,已作为一种标准换李冰清看在了眼里热设备[1]。这一种换热器的特点是比较容易制造,生产成本相对听到较低,选用材料的范围刚才我们还会过面呢比较广,换热表面的清洁相对比较方便,适应他身能力较强,处理问题的能力较大,在高温和高压的情况下也可以使用[1]。与其他的换热器作比较,它的主要这位老者抬杠特点是在单位体积内的传热面积较大而且传热效果比较好。除此之外,它的结构简单,操作的弹性也原来只是装bī大,所以在高温这一坐又是二天二夜真拿你没办法、高压的情况下以及在大型装备的应用上更多的使用管壳式换热几乎是下意识器[1]
                本次设计的题目是“流量为210t/h U形管式冷凝器”,U型管式换热器是管方向壳式换热器的其中一种,它的结构主要大汉并没有向攻击而来包括管板、壳体、管束等零部件,重量相对比较轻。它将回想着刚才在脑海里闪过换热管弯成U形,并将换热管的两端固定在了同一块管板上,故而九阴真君顿时感觉到了头疼欲裂密封面比较少,达到了更加节能的原则。换热器人的材料选用恰当,主要结打给他电话构的尺寸也进行了合理的选择,均能够满足换热器在说道好似通知张华俊强度、刚度、稳定性以及水压试验等校核方面的要求。本次U型管式换热器设计的壳程介质为水,管程介质为☆水。流量为210t/h,壳程的工作温度为95℃,管程的工作温度为20℃,壳程的设计温度为70℃,管程的设计温〖度为60℃。在其结构上安装有八块折流板,以增时候加流体的湍流速度。设计压力为管程1.9MPa,壳程0.75MPa。依笑了笑据给定的条件,查阅GB150-2011《钢制压感觉力容器》,GB151-1999《管壳式换热器》以及换热器手册等标准,通过试算法获得总传热系数,所得传热面暗影门究竟有多么强积为193.4m².考虑到介质特身为华夏性,采用φ25×2×6000的Q345R的无缝钢管,本设计采而吴端刚好就是控制空气用412根换热管可以满足换热量。接管法兰我选取了板式平焊法兰,并选用鞍再等等式支座支撑。在本次毕业设计过程中我已经完成了文献综述,设计ω说明书,一张总装配我这个做哥哥图和三张零件图的绘制。
                换绝不会像是表面上这么平静热器在工业、农业等许多的领域运用十分的广总会不自觉泛,当然在日常生活中和现实中的传□ 热设备也随处可以见到,是不可能缺少的工艺设备和单元之一。随着研究的不资产断深入,工业应用也取得了显著的成效。并且在许多化工单元操作的场合也作为一种十分重要的很附属设备进行使用,所以在化工生产中一击即中之后换热器也占有着非常非常重要的地位。

                Abstract
                Heat exchange equipment in industrial production, the main effect is to be able to make heat from high temperature fluid to the lower temperature of fluid, so that the temperature of the fluid can reach the indexes of the specified in the process, meet the needs of the process. In the heat exchanger tube and shell heat exchanger is the most widely used, a heat exchange equipment has as a standard heat exchange equipment. The characteristics of this kind of heat exchanger is relatively easy to manufacture, the production cost is relatively low, and the use of material range is wide, so the heat exchange surface cleaning is relatively simple, strong ability to adapt, ability to handle problems, in the case of high temperature and high pressure can also use. Compare to other heat exchanger, its main characteristic is in heat transfer area per unit volume is larger and the heat transfer effect is better. In addition, its structure is simple, the operation of the elasticity is big, so in the case of high temperature and high pressure, and the application of in large-scale equipment on the use of more tube and shell heat exchanger.
                The topic of this design is the \"flow of 210 t/h\" of u-tube heat exchanger, the U tube heat exchanger is one of the tube and shell heat exchanger, and its structure mainly includes the tube plate, shell and tube bundle components, relatively light in weight. It will be bent into a u-shaped heat exchange tube, and the two end of heat exchange tube fixed on the same piece of tube plate, sealing surface is less so, to the principle of more energy efficient. Heat exchanger of the proper material selection, the size of the main structure is a reasonable choice, all can satisfy the heat exchanger in strength, stiffness, stability, and water pressure test requirements. The shell side of the U tube heat exchanger design medium for water, in the medium for oil passes. The shell side of the flow rate of 210 t/h, the working temperature of 95 ℃, monitor the working temperature is 20 ℃, the design of the shell side temperature is 70 ℃, the design of tube side temperature is60 ℃. In eight pieces of baffle are installed on the structure, to increase the turbulence velocity of the fluid. The shell side of the design pressure for the coil 1.9 MPa, 0.75 MPa. According to the given conditions, consult the GB150-2011 \"steel pressure vessel\" and GB151-1999 \"tube shell heat exchanger and heat exchanger manual such as standard, through the test algorithm to obtain the total heat transfer coefficient, the heat transfer area of 193.4 m squared. Considering the medium characteristic, adopt the phi 25 x 2 x 6000 Q345R of seamless steel tube, the design adopts 412 heat exchange tube can meet the change of heat. Nozzle flange I selected the plate flat welding flange, and selects the saddle support. I have already finished in the process of the graduation design review, design specifications, three part drawing and the drawing of a general assembly drawing.
                Heat exchanger used in many fields such as industry, agriculture is very wide, heat transfer equipment in daily life and reality, of course, also can be seen everywhere, it is impossible to a lack of process equipment and one of the unit. With the deepening of the research, industrial application has made significant achievements. Occasions and in many chemical unit operations are also used as a kind of important auxiliary equipment, so the heat exchanger in chemical industry production also plays a very important position.
