摘要
换热器是一种在不同温度的两种或两种以上流体间实现物料间热量传递的节能设备,可使热量由温度较高的流体传递给温度较低的流体,从而使流体温度达到规定指标、满足工艺条件的需求,同时,也是提高能源利用率的主要设备之一。换热器是化工生产的主要设备,占有非常重要的地位,可作为加热器、冷却器、冷凝器、蒸发器和再沸器等形式使用,应用非常广泛。
The heat exchanger is a kind of heat transfer between the materials of energy-saving equipment in different temperatures of two or more than two kinds of fluids, can make the heat transmitted by the high temperature of the fluid to fluid temperature is low, so that the fluid temperature reaches the specified indicators meet the conditions of the demand. At the same time, but also improve the energy utilization rate of one of the main equipment. Heat exchanger is the main equipment of chemical production, it is of great importance, and can be used as heater, cooler, condenser, and evaporator and re boiling.
