摘　　要：在分馏塔开孔率和微反应理论基础上,分析了板式塔流体力学性能的影响因素,重点论述了分馏塔塔盘升气阀尺寸对分馏效果的影响,在此基础上引入了分馏塔塔盘气液接触微界面理论和气液接触界面系数的概念。通过工业应用证实,微型升气阀的应用,能够大幅提高分馏塔的生产能力,改善气液接触和分离效果,经济效益明显,是石油化工技术的一项重大突破。On the basis of the fractionator opening rate,the influencing factors of plate tower fluid mechanical properties were analyzed.The influence of the size of the riser valve on the fractionation effect was discussed.The concept of gas-liquid contact micro-interface theory and gas-liquid contact interface coefficient was introduced on the basis of the existing micro-reaction theory.The industrial application proves that the application of micro-lift valve can greatly increase the production capacity of fractionator and improve the gas-liquid contact and separation effect,which is a major breakthrough in petrochemical technology.
