【摘要】：在直徑為476 mm的有機玻璃塔內對新開發(fā)的HSX型填料進行冷膜實驗,測試不同比表面積的HSX型填料的流體力學性能和傳質性能,并將HSX125型填料與Mellapak125X型填料的實驗數(shù)據(jù)進行對比。實驗結果表明:HSX125型填料無論在濕塔壓降、液泛氣速及傳質效率上均優(yōu)于Mellapak125X型填料;當噴淋密度L=28.11m3/(m2·h)時,HSX125型濕塔壓降比Mellapak125X平均降低30.8%,等板高度平均降低16.2%;在實驗操作條件下,HSX125型填料的液泛氣速平均升高5.6%。上述結果表明,HSX型填料經(jīng)波紋結構優(yōu)化后,在保證填料塔大通量的前提下也保持了其較高的傳質效率。
[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.
