Abstract

The utility model relates to the technical field of gas-liquid redistributors, and discloses a gas-liquid redistributor for a small packed tower, which comprises a distribution plate, gas uniform distribution holes and liquid uniform distribution holes are arranged on the distribution plate and are arranged on different circles taking the center of the distribution plate as the center, and the gas uniform distribution holes and the liquid uniform distribution holes are arranged on each circle. The gas uniform distribution holes and the liquid uniform distribution holes are alternately distributed, the distances between two adjacent circles are equal, and the liquid distribution holes of the two adjacent circles are distributed in a staggered manner; a gas distribution pipe and a liquid distribution pipe are respectively arranged above and below the distribution disc, the gas distribution pipe is connected with the gas uniform distribution holes, and the liquid distribution pipe is connected with the liquid uniform distribution holes. The gas-liquid redistributor disclosed by the utility model is suitable for being used in a small-sized gas-liquid mass transfer packed tower, has a simple structure, cuts a gas phase into smaller gas flows, uniformly distributes liquid into smaller liquid drops, and increases the contact area between the liquid and the gas, thereby improving the mass transfer efficiency.
