4、 05 月 29 日回流冷凝器设计摘要：传热过程是化工生产过程中存在的及其普遍的过程，实现这一过程的换热设备种类繁多，是不可缺少的工艺设备之一。由于使用条件不同，换热设备可以有各种各样的型式和结构。其中以管壳式换热器应用更为广泛。现在，它被当作一种传统的标准换热设备在很多工业部门中大量使用，尤其在化工、石油、能源设备等部门所使用的换热设备中仍处于主导地位。 回流冷凝器是换热设备中的一种，是企业生产中的重要设备。它的作用是通过温度相对较低的水来冷凝温度较高的气体从而保证精馏塔液相产品的摩尔分率，从而使设备部分的温度保持在一个生产所需要的水平，使设备正常工作。因此，循环水冷却器的设计对企业的生产是
5、很重要的，它很可能影响企业的经济损失，对其的设计具有很强的实际意义。首先查阅相关文献资料了解回流冷凝器的基本原理、性质及应用，在化工生产中的地位和作用、回流冷凝器应用的现状和发展趋势、设计的理论基础、技术路线及其意义，对回流冷凝器设计有一个大体上的认识和理解。然后根据工艺要求进行工艺流程计算，确定设备类型、结构，并完成设备工艺设计部分，借助化工模拟软件完成。接着完成回流冷凝器结构设计与部分零部件选型，进行设备强度校核，利用SW6软件包完成设备的强度计算，并以此计算结果作为最终结果，完成设计计算说明书。最后利用计算绘图软件绘制设备的整套设计图纸。关键词：换热器、换热面积、管板、换热管。 Refl
6、ex condenser designAbstract: The reflex condenser is the chemical production process of existence and its general process, heat equipment for this process is various, is one of the indispensable process equipment. Due to the use of different conditions, heat exchange equipment can have various types
7、 and structure. The tubular heat exchanger applied more widely. Now, it is regarded as a kind of traditional standard heat exchange equipment widely used in many industrial departments, especially used in chemical, petroleum, energy equipment department.Heat transfer equipment is still in a dominant
8、 position. Reeflex condenser is a change of thermal equipment, is the important equipment in the production. It is the role of the relatively low temperature water to take away the heat generated by the other device, so as to make part of the temperature is maintained at the required a production le
9、vel, so that the normal operation of the equipment. Therefore, the production design of circulating water cooler of enterprise is very important, it is likely to affect the economic losses of enterprises, which is of great practical significance to the design. This design is for the study of fixed t
10、ube plate heat exchanger on the tube shell type. A fixed tube plate heat exchanger, belonging to the shell and tube heat exchanger, is the use of the high temperature fluid and wall temperature fluid of convective heat transfer and heat transfer between the material. In this design, the GB 150-2011
11、, GB 151-1999 pressure vessel shell and tube type heat exchanger standards and fixed pressure vessel safety technology supervision regulation as the basis, and with reference to Design Handbook heat exchanger, the scheme is demonstrated, to determine the physical material parameters, combined with t
12、he working conditions, select the type of heat exchanger. According to the design task, determine the process parameters on the heat transfer area, the total heat transfer coefficient, and heat transfer area, wall temperature and pressure drop calculation. Then the mechanical design based on process
13、 parameters, mechanical design including the tube, tube box, tube plate, baffle, head, tube heat exchanger, saddle and other parts, such as the bar, fixed pitch pipe calculation and selection, and calculated the strength necessary, finally using AutoCAD drawing fixed tube plate heat exchanger the assembly diagram and parts diagram, and writing a specification.关键词：换热器、换热面积、管板、换热管等。keyword:tube sheet,heat exchange tube.目 录1 概述 .1 1.1 选题的根据和意义 .1 1.2 本设计的目的和要求 .2 1.3 国内外现状和发展趋势 .22 管壳式换热器的分类和选型 .
