摘　　要：应用空气 -水系统 ,在直径 60 0 mm的塔内 ,对矩形微分浮阀塔板的流体力学进行了试验研究 ,测定了临界孔速、塔板压降、雾沫夹带率和流体泄漏率 ;应用空气 -水 -氧气物系 ,测定了矩形微分浮阀塔板的传质效率 ;并与 F1型浮阀塔板进行了比较。结果表明 ,矩形微分浮阀塔板具有良好的流体力学和传质性能。对试验数据进行了关联 ,获得了计算阀孔临界气速、塔板压降、雾沫夹带率和泄漏点孔速的关联式 ,可用于该塔板的设计计算。The hydrodynamics of the rectangle microdispersion valve (RMDV) trays were experimentally studied with an airwater system in a φ 600 mm circular column. Critical gas velocity through valve holes, pressure drop, entrainment and weeping were measured. The plate mass transfer efficiency of the RMDV trays was determined using airwateroxygen system. Both the hydrodynamics and plate mass transfer efficiency were compared with type F1 valve trays. The experimental results showed that the RMDV trays possessed better characteristics on the hydrodynamics and mass transfer. The hydrodynamic experimental data of the RMDV trays have been correlated and the models of critical gas velocity through valve holes, pressure drop, entrainment and gas velocity through valve holes at weeping point have been obtained, which can be used to design the RMDV trays.
