Based 011 analyzing research status and existing problems of Packed Column that wall flow effect and larger effect influence on development of Packed Column in this paper,the mass transfer model of Equal Probability Packed Column,which solved wall flow effect and
larger effect of Packed Column,is given.
Division scheme of equal probability packing cell·grid was test systems of the Equal Probability Packed Column Was designed to determine wall flow,pressure drop and transfer efficiency of equal probability an experimental round plexiglasses column of巾600 x 1 2ram,the behaviors of Pall ring random packings,equal probability packing and corrugated structured packing were tested with air-water-oxygen the experiment of the ordinary Packed Column and Equal Probability Packed Column,many hydraulie
properties,such as wall flow,pressure drop and transfer efficiency,were measured,and parative research is also done with wall flow,pressure drop and transfer efficiency,It
showed that,pared with the corresponding properties of the ordinary Packed
Column wall flow respectively,the wall flow of the Equal Probability Packed Column is
lowered by %'--%,the pressure drop is almost the same,the transfer efficiency is improved by %---%.Parameters of the wall flow mathematical model were determined
by experiment,which got through material balance,then wall flow equations of Pall ring random packings,equal probability packing and corrugated structured packing were determined.
putational fluid dynamics)model of gas,liquid—phase flow Was established in the Packed Column by the volume averaging technique,which through definition of the Representative Elementary Unit(I也U).A numerical simulation Was conducted for the flow behavior of fluid in the ordinary Packed Co
