摘　　要：填料塔内液体流动分布状况直接关系到塔内气液两相的有效接触,影响塔的操作性能.由于液体分布不良,造成填料塔内局部区域的气液比与全塔宏观的气液比有显著差别,从而大大降低塔的总传质效率.因此。According to the structure of Mellapak type packing, liquid flow and mixing mechanisms were analyzed in gas - liquid counter - contacting packed column. A new liquid flow distribution mathematical model , specific for Mellapak type packing columns, was presented. Experimental data of the liquid flow distribution measurements agreed quite well with the theoretical prediction. Furthermore, the effects of gas initial maldistribution and gas load on liquid flow distribution were discussed, and the wall zone liquid flow was preliminarily studied.
