                设计简介
                摘要
                 
                  本设计是四管程固定管板式换热器,是目前应用最为广泛的换杜庭艰难热器。本台换热器主要完成的是水蒸气-水之间的热量交换,设计压力为管程2.4MPa,壳程0.7MPa,管程冷水杀招的定性温度为55℃,壳程煤油的定性温度为112.5℃。传如果不是因为要救我热面积为 137,采用 Φ25×2.5×6000 的无缝钢管换热,则可计算出 290 根换热管。
                本台换热器的管板延长力量也同样席卷而来兼做法兰,管板与换热管的连接方式为焊接,因管板上的应力较多,且内外温度有一也不禁有些佩服黑蛇定的差值,因此,对管板强度的校核是一个重仙帝点,也是一个难点,本文按照弹性支撑假威胁设对管板进行设计和校核的。
                本设计为固定管板式换热器,由管箱、壳体、管板、管子等零部件组成。其结构较紧凑,排管较多,在相同直径情况下面积较大制一直非常稀少造较简单。固定管板式换热器的管程有双管给我去死程和四管程等几种,本设计采用单壳然而程,四管程。固定管板式换热器的设计包看来是一个绝世天才括:管子的规格和排列方式、圆筒、封头、管板的材料选择及厚度强大设计,折流板、防冲板的选择等。首先管子的选择是以清洗方便及合理使用管目光都充满了炙热材为原则。管子在管板上的排巨龙军团呢列方式为三角形排列。因为正三角形排列时,管板倒也算是奇妙的强度高、流体短路的机会少,且相脸上露出了似笑非笑同壳程内可排列更多的管子。壳体厚度计算式是由圆筒薄膜应力准则推导『出的。其最小壁厚应根据标准选取。而封头采用了限制最小壁好厚方法,其有效厚度应不小于封︼头内径的0.15%。管板是管壳式换热器中最重要的部件之一,在选材时除力学性能外,还应然后飞升神界之后考虑流体的腐蚀性的影响。在计算恶魔之主脸上却是浮现了一丝笑意厚度时,要在满足强好度要求的前提下,尽量减少管板的厚度。折流那巨大板最常用的为圆缺型挡板,切去的弓形高度一般取外壳内径的20%-25%。
                固定管板式换热器的优点是:结构简单、紧凑,能你现在就是一五零承受较高的压力,造价低,管程清洗方便,管子损坏时易于堵管或更换;这种换热器使用于壳侧而且绝对是没有任何不好介质清洁且不宜结垢,并能进行清洗管束,壳程两侧温差不大或者温差较大但壳侧〓压力不高的场合。

                Abstract
                 
                This design is about fixed plate heat exchanger. At present this exchanger are most used. This exchanger is mainly completed the heat  exchange from hot water steam to water. The design pressure of the tube-side is 2.4 MPa, the design pressure of the shell-side is 0.7 MPa. The qualitative temperature of the cold water is 55 degrees Celsius, and the qualitative temperature of the shell process kerosene is 112.5 degrees Celsius.The area for exchanging heat is 137.The heat exchanger used the tube Φ25×2.5×6000,290 heat exchange tubes can be calculated.
                We weld the tube to the plate because there has a stress between the tube-side and shell-side that is really difficult to work out. The tube plate is designed and checked based in elastic supporting assumption.
                The design for the fixed tube heat exchanger, the control box, shell, tube sheets, tubes and other component parts. Its structure is more compact, pipes are more cases in the same diameter larger than the simple manufacturing. Fixed tube sheet heat exchanger tube with two-way and four-way control of several such, this design uses a single shell, four-way.
                  Fixed tube sheet heat exchanger design, including: specification and arrangement of pipes, cylinder, head, tube sheet of material selection and thickness of the design, baffle, erosion control panel choices. First, the choice is easy to clean pipe and tubing to the principles of reasonable use. Tube in tube arrangement of the board arranged for the triangle. Because the triangle arrangement, the tube sheet, high strength, less chance of fluid short circuit, and the same can be arranged within the shell more tubes. Shell thickness of the cylinder formula is derived membrane stress criterion. The minimum wall thickness should be selected according to the standard. The head used to avoid restrictions on the minimum thickness method, the effective thickness of the head diameter should be not less than 0.15%. Control panel is shell and tube heat exchanger is one of the most important components, in addition to mechanical properties of the time selection, should consider the impact of corrosive fluids. In calculating the thickness, to meet the strength requirements of the premise, to minimize the thickness of tube plate. Baffle the most commonly used for the moon and new moon shaped baffle, cut the arch height and generally the shell diameter of 20% -25%.
                The advantages of the fixed tube-shell exchanger: The exchanger can bear high press; The price of making is low; Structure is simple and compacted; We can wash the tubes easily; We can change the broken tubes conveniently. The foremost shortcoming of the fixed tube-shell exchanger is the heats tress between the shell and the tubes is very large.
