采用空气-水-氧气物系，在内径为Φ600mm，塔板间距为350mm的冷模精馏塔内，分别研究了带有14个浮阀的FGS-VT-14塔板和带有8个浮阀的FGS-VT-8塔板的流体力学与传质性能。根据实验数据，回归得到了FGS-VT-14塔板的干板压降和湿板压降关联式分别为Δp_d=ξu²_hρ_g/2和Δp_w=a₁Fⁿ_hL^m_w。实验结果表明，与FGS-VT-8相比，FGS-VT-14的干板压降降低3%、湿板压降降低16%（浮阀升起后）、漏液降低90%、雾沫夹带升高55%、塔板效率增大12%，具有更好的综合性能；与导向筛板相比，FGS-VT-14塔板的操作性提高了10%~20%、塔板效率提高了7%、湿板压降降低了8%（浮阀升起后）。

The performance of two types of flow-guided sieve tray with 14 and 8 valves (FGS-VT-14 and FGS-VT-8, respectively) has been studied in an air-water-oxygen system within a 600mm diameter plexiglass column with a 350mm tray spacing. The regression models of the dry-plate pressure drop (Δp_d=ξu²_hρ_g/2) and wet-plate pressure drop (Δp_w=a₁Fⁿ_hL^m_w) of FGS-VT-14 were obtained from the experimental data. The results indicated that the performance of FGS-VT-14 was better than FGS-VT-8 because its dry-plate pressure drop, wet-plate pressure drop (when the valves start to open) and weeping were reduced by 3%, 16% and 90%, respectively, and the tray efficiency was improved by 12%, although the entrainment increased by 55%. Compared with conventional flow-guided sieve trays, the operating flexibilities of the two FGS-VT units were improved by 10%-20%, and the tray efficiency increased by about 7%. On increasing the gas velocity, the pressure drop decreased by about 8%. 
