摘要

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.
