| 摘 要： | 以空气-水为物系，在内径为500mm的有机玻璃塔内测定了不同喷淋密度下BH800、BH1000型金属丝网规整填料的流体力学及传质性能,比较了气相动能因子与单位填料层压降及传质系数的关系。结果表明：当液体流量增大时，填料层的压降增大，而单位填料层等板高度减小；在相同喷淋密度及动能因子下， BH1000型的压降大于BH800型； BH800型填料的操作弹性较优，但传质效率远远低于BH1000型；丝径变小可以提高传质性能且对工况操作弹性影响较小。

| Abstract: | In order to optimize design considerations,the hydrodynamic and mass transfer performance of BH800 and BH1000 metal wire structured packings developed by our laboratory were studied.The pressure drop and mass transfer efficiency of the BH-series packings were investigated under conditions of different gas and liquid loads with an air-water system in an organic glass tower with a diameter of 500 mm.The results show that the pressure drop rises with increasing liquid flow rate and the value of the height equi... |
