Abstract

The utility model discloses an efficient purification ammonia-containing tail gas absorption tower combined structure which comprises a shell, supporting legs are fixedly connected to the lower end of the shell in a circumferential array mode, an air inlet channel is formed in the middle of the lower surface of the shell, a honeycomb frame is clamped in the middle of the interior of the shell, and a filler frame is clamped in an inner channel of the honeycomb frame. A connecting frame is fixedly connected to the upper end of the interior of the shell, a fixing groove is formed in the upper surface of the connecting frame, a demister is clamped in the fixing groove, the middle of a filler frame is of a hexagonal structure, an inserting groove is formed in the outer side face of the filler frame, the demister is a folding plate type demister, and a limiting block is fixedly connected to the outer ring side of the upper surface of the demister. A packing layer and a demisting layer are optimally combined, and the packing layer adopts special structured packing and has the characteristics of large specific surface area and high mass transfer efficiency, so that ammonia-containing tail gas can be in full contact with absorption liquid, and efficient absorption is realized.
