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

In order to deal with the “wall flow effect” and the “scaling effect” that commonly exist in packed tower, a new type of 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 experimental and numerical simulation, and the results such as wall-flow contours and velocity distribution were given. The study results showed that the wall flow was significantly reduced by about 31% and the gas-liquid velocity was more uniformly distributed compared to the normal packed tower. The results showed that the symmetrical-flow packed equipment had a very good effect on improving the uniform distribution of the macroscopic flowing of fluid. The symmetrical-flow packed equipment, therefore, can effectively reduce the “wall-flow effect” and eliminated the “scaling effect”, and also increase the mass transfer efficiency of the packed tower is improved.
