A filter plate 4 is fixedly installed on the inner wall of the tower body 1 and is obliquely arranged below the reaction layer. A collection filter box 5 detachably connected to the tower body 1 is arranged at a lower end of the filter plate 4. The filter plate 4 is provided with a collection filter box 5 detachably connected to the tower body 1.
