Absorption tower for bromine extraction

The utility model discloses an absorption tower for bromine extraction, which belongs to the technical field of absorption towers and comprises an absorption tower body, two filler supporting plates are fixedly arranged in the absorption tower body, and the two filler supporting plates divide the internal space of the absorption tower body into a first filler cavity, a second filler cavity and a liquid collecting cavity from top to bottom. According to the tank-type liquid redistributor, the water collecting tray is additionally arranged below the traditional tank-type liquid redistributor, so that the liquid in the tank-type liquid redistributor can be effectively redistributed, and the liquid in the tank-type liquid redistributor is uniformly distributed; the problem that liquid discharged during drainage of a traditional liquid redistributor only gathers at the same position is solved, meanwhile, the water collecting disc is driven by gas in the gas inlet pipe to rotate, accumulated water in the groove-sha
