摘要
换热器数量占总设备的40%左右,在化工生产中起着重要作用,提高其传热效率,进而实现能源的高效利用,具有现实意义。阐述换热器管程与壳程的强化传热技术,从管程的管型变化与壳程的支撑结构2个方面进行改进,通过增加管壳程冷热流质的湍流程度使其换热更加充分,以实现单位传热面积上热效率的最大化,进而促进能源利用率与经济效益的提高,达到高效节能的效果,为换热设备管壳程结构进一步优化提供新思路和新技术。
The number of heat exchangers accounts for about 40% of the total equipment, it plays an important role in chemical production, it is of practical significance to improve the heat transfer efficiency and realize the efficient utilization of energy resources. Heat transfer enhancement technology of tube side and shell side of heat exchangers are expounded, it is improved from two aspects of tube type change and shell side support structure, by increasing the turbulence level of the cold and hot fluid in the shell and tube makes the heat transfer more sufficient, in order to maximize the thermal efficiency per unit heat transfer area, and promote the improvement of energy utilization and economic efficiency, to achieve the effect of high efficiency and energy saving, New ideas and new technologies are provided for further optimization of shell-and-tube side structure of heat exchange equipment.
