摘　　要：气液并流填料塔板是一种新型的高通量复合塔板 ,以空气 /水体系在直径为 2 85mm的有机玻璃塔内对其流体力学性能进行了测试 ,实验证明这种塔板的压降和雾沫夹带比NVST塔板都有所减小 ,而提升量比NVST要大得多 ,是一种很有应用前景的塔板。Modern industry set more and more strict requirements on the capacity and energy consummation of the columns,and jet coflow packing tray(JCPT) is a kind of high capacity packing tray.In this paper,the hydrodynamics of JCPT was tested with an air/water system in a column with a diameter of 285mm.Results show that JCPT has lower pressure drop/stage and entrainment and higher liquid lift-up than NVST tray, indicating JCPT' good commercial future.
