Study on Wall-Flow of a New Type of Efficient Uniform-Flow Packed Equipment

Abstract:

In order to deal with the wall flow effect and the scaling effect because of uneven distribution of fluid overall that commonly exist in packed tower, a new type efficient symmetrical-flow packed equipment was developed. In the same condition, the symmetrical-flow packed equipment was studied comparatively with the common packed equipment by experiments and numerical simulation, and the results such as pressure drop, wall-flow contours and velocity distribution were given. The study results show that the pressure drop of two kinds of packed tower have no significant differences , wall flow is significantly reduced by about 31%, gas-liquid velocity uniformly distribute compared with ordinary packing. The result demonstrate that the symmetrical-flow packed equipment has good effect tin improving the uniform distribution of the macroscopic flowing of fluid, the wall flow effect of the symmetrical-flow packed equipment can be effectively reduced, and the scaling effect eliminated. So the mass transfer efficiency of the packed tower is improved.
