摘　　要：在直径为476 mm的有机玻璃塔内对新开发的HSX型填料进行冷膜实验,测试不同比表面积的HSX型填料的流体力学性能和传质性能,并将HSX125型填料与Mellapak125X型填料的实验数据进行对比。实验结果表明:HSX125型填料无论在湿塔压降、液泛气速及传质效率上均优于Mellapak125X型填料;当喷淋密度L=28.11m3/(m2·h)时,HSX125型湿塔压降比Mellapak125X平均降低30.8%,等板高度平均降低16.2%;在实验操作条件下,HSX125型填料的液泛气速平均升高5.6%。上述结果表明,HSX型填料经波纹结构优化后,在保证填料塔大通量的前提下也保持了其较高的传质效率。Cold pilot model experiments have been conducted in a 476 mm-diameter plexiglass column packed with new type of HSX type structured packing material. The hydrodynamic performance and mass-transfer efficiency of the HSX type packing materials with different specific geometrical areas was analyzed and HSX125 was compared with commerial Mellapak125 X. The HSX type packings were better than Mellapak125 X in respect of the wet pressure drop,the flooding gas and mass transfer efficiency：when L = 28. 11 m3/（m^2·h）,the wet pressure drop of HSX125 was 30. 8% lower than that for Mellapak125 X,the HETP decreased by 16. 2%,and under the experimental operating conditions,the flooding gas velocity was 5. 6% higher for HSX125. As a consequence of the highly effective geometry of the modified packing,the capacity of the HSX type packings materials is increased without any adverse effects on mass-transfer efficiency.
