浮头式换热器设计摘要： 换热设备的主要作用是使热量由温度较高的流体传递给温度较低的流体，使流体温度达到工艺过程规定的指标以满足工艺过程上的需要。浮头式换热器是应用最广泛的管壳式换热器中的一种.浮头式换热器的两管板中只有一端与壳体固定，另一端可相对壳体自由移动，称为浮头。浮头由浮动管板钩圈和浮头端盖组成，是可拆连接，管束可从壳体内抽出。管束与壳体的热变形互不约束，因而不会产生热应力。该设计的浮头式换热器主要参照GB151在给定的设计条件下进行工艺设计然后对筒体、管束、浮头端，进行详细的机械结构设计、计算和校核对于换热器的一些零部件则根据设计参数查找标准。各设计步骤以及设计准则在说明书中都将说明关键字 : 管板 浮头 浮动管板 钩圈 The design of Floating-head heat exchangerAbstract: The main function of heat exchanger is to heat the fluid by the high temperature transfer fluid to a lower temperature, so that the fluid temperature reaches the target set to meet the needs of the process. Floating head heat exchanger is one kind of the most widely used shell and tube heat exchanger floating head heat exchanger has two platets , only one plate fixed in the shell and the other plate can move freely comparate to shell, as the floating head. Floating head consist of floating tube sheet , hook ring and floating head cover, is removable connection, control can be extracted from the shell . Control of thermal deformation and the shell are not binding and therefore does not produce thermal stress. The design of the floating head heat exchanger major reference GB151, first make process design in a given design conditions and then on the cylinder, tube, floating head end, a detailed mechanical structural design, calculation and check .for heat exchanger parts find the standard accordance with design parameters. The design steps and design criteria in the brochure will exp
