【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。
[Abstract]:The cold film experiment of newly developed HSX type filler was carried out in an organic glass tower with a diameter of 476 mm. The hydrodynamic and mass transfer properties of HSX type packing with different specific surface area were tested. The experimental data of HSX125 type packing and Mellapak125X type filler were compared. The experimental results show that the mass transfer efficiency and the flow rate of liquid in the wet tower are better than those in the Mellapak125X type packing. When the spray density is L=28.11m3/(m2 h, the pressure drop of HSX125 type wet tower is 30.8 and 16.2% lower than that of Mellapak125X, and the liquid gas flow rate of HSX125 type packing increases 5.6% under the experimental operation condition. The results show that HSX type packing has high mass transfer efficiency on the premise of ensuring large flux of packing tower after corrugated structure optimization.
