摘　　要：应用空气－水物系，在直径为６００ ｍ ｍ 的塔内，对ＡＤＶ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、雾沫夹带率和液体泄漏率。应用空气－水－氧气物系，测定了ＡＤＶ 微分浮阀塔板的传质效率，并与Ｆ１ 型浮阀塔板进行了对比试验研究。试验结果表明，ＡＤＶ微分浮阀塔板比Ｆ１型浮阀塔板具有更好的流体力学和传质性能。通过对试验数据进行回归，获得了计算临界孔速、塔板压降、雾沫夹带率和泄漏点孔速的关联式，用于ＡＤＶ 微分浮阀塔板的水力学计算。并介绍了ＡＤＶ 微分浮阀塔板的工业应用情况。The hydrodynamics of the advanced micro dispersion valve (ADV) trays and F 1 valve trays were experimentally studied with an air water system in a Φ600 mm circular column. Critical gas velocity through valve holes, pressure drop, entrainment and weeping were measured. The plate efficiencies of the ADV trays and F 1 valve trays were determined using air water oxygen system. The experimental results showed that the ADV trays possessed better characteristics than F 1 valve trays on the hydrodynamics and mass transfer. The hydrodynamic experimental data of the ADV trays have been correlated and the correlation equations 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 ADV trays. The industrial applications of ADV trays are introduced.
