摘　　要：采用空气-富氧水体系,在直径1200 mm不锈钢塔内,对EJT喷射塔板的流体力学与传质性能进行了研究,回归了压降、漏液和雾沫夹带等计算关联式,并与新垂直筛板进行了对比实验.结果表明,与新垂直筛板相比,EJT喷射塔板的压降减少16%左右,漏液率基本相当,雾沫夹带率降低20%左右,传质效率提高3%～10%,是一种综合性能优异的塔板.A new kind of tray,enhanced jet tray(EJT),was presented.The hydraulic and mass transfer performances of EJT and new vertical sieve tray(New VST) were investigated with air-water-oxygen system in a stainless steel column of 1 200 mm internal diameter.Equations of hydraulic parameters such as pressure drop,weeping and entrainment were regressed.The experimental results show that EJT has 16% lower pressure drop,the same weeping rate,20% lower entrainment and 3%～10% higher efficiency compared to New VST,which indicates that EJT has super performance.
