管壳式换热器 摘 要 换热器是在工厂生产中最常见的过程设备之一，是用于物料之间进行热量传递的过程设备，使热量从热流体传递到冷流体的设备。通过这种设备使物料能达到指定的温度以满足工艺的要求。浮头式换热器是针对固定管板式换热器在热补偿方面的缺陷进行了改进的换热设备。 本设计说明书是关于浮头式换热器的设计，主要分为说明和计算两部分。说明部分主要叙述了换热器的特点和分类、换热器的发展现状、国内发展趋势和研究热点，以及浮头式换热器主要零部件结构的设计及压力容器常用材料等。计算部分主要对浮头换热器的筒体、封头和法兰进行了详细地计算，并对其进行了水压试验的校核；其中，换热管、管板、折流板、鞍座和钩圈等各个受压元件按照的标准进行 Shell and tube heat exchanger Abstract 　 Heat exchanger is used in the materials to carry on the thermal transmission the process. Through this kind of equipment，materials achieve assignment the temperature to satisfy the craft the request. Floating head heat exchanger tube against a fixed plate heat exchanger in the thermal compensation of the defects and improved heat transfer equipment. The design manual is about floating head heat exchanger, which included explanation part and calculation part.And the explanation part described the characteristics and classification of heat exchanger, the development of the status quo, development trend of domestic and research hot spots, also the floating heat exchangers’ design of the structure of the main components and pressure vessels commonly used materials. The main part of the calculation of the cylinder, head and flange of the calculation in detail, and its verification of hydraulic test; also heat exchanger, tube sheet，baffle，circle hooks，such as saddles and all by pressure components in accordance with the GB150-1998 Steel Pressure vessel and GB151-1999 Tubular heat exchangers standard for strength calculation, checking water pressure test intensity to yield stress in the range of allowable stress. In addition, see the related design manuals and a lot of literature, completed the mapping of various parts, but also a translation of a foreign languages and so on. Keywords: floating head heat exchanger; thickness calculation; strength check; pressure test 目 录 1 换热器概述 1 1.1 换热器的特点 1 1.2 换热器的分类及其优缺点 2 1.3 浮头式换热器的简介 2 1.4 换热器的研究热点 4 2 浮头式换热器的设计 6 2.1 设计参数的确定 6 2.1.1 设计压力 6 2.
