【摘要】 应用空气－水系统，在１６００ｍｍ×４００ｍｍ的矩形塔内，对导向浮阀塔板的流体力学进行了实验室研究，测定了塔板压降、雾沫夹带率和液体泄露率。应用空气－水－ＣＯ２物系，测定了导向浮阀塔板的效率，并与Ｆ１型浮阀塔板进行了比较。试验结果表明，导向浮阀塔板具良好的流体力学和传质性能。更多还原

【Abstract】 The hydrodynamics of the directed floating valve trays were experimentally studied with an air water system in a 1 600×400mm rectangular column. Pressure drop, entrainment and weeping were measured. The plate efficiency of the directed floating valve trays was determined using air water CO 2 system. Both the hydrodynamics and plate efficiency were compared with type F1 floating valve trays. The experimental results showed that the directed floating valve trays possessed better characteristics on the hydrodynamics and mass transfer.更多还原
