This invention teaches a packed column, comprising an outer cylinder, a support plate, and a plurality of fluid balls, wherein an inner cylinder is connected to the center of the support plate, and a plurality of openings and deflectors connected to the openings are disposed on the circular edge of the inner cylinder. By setting a circular spin and planetary travel path for the fluid balls, a series of problems influencing the mass transfer speed are solved. This invention has the following characteristics: 1) the technical problems such that the gas and liquid contact area of static bed packing is small and the operation of turbulent bed is unstable are solved completely; 2) the spray liquid is utilized completely, the consumption of the spray liquid is reduced and the operation cost of the reflecting packed column is decreased; and there is no stringent requirement on the pressure and atomization degree to the spray liquid; 3) the mass transfer effect having a low resistance and high efficiency can be achieved without increasing the air pressure; 4) an absorption liquid circulation system with dual or more loops can be realized; the purpose of multilevel flow split and multistage liquid processing can be reached; and 5) the reflecting packed column has a simple structure and has fewer easily worn-out parts; the scaling buildup can be avoided resulting from the planetary motion of the fluid balls. The reflecting packed column of this invention is applicable to various mass transfer processes.
