Strong mass transfer self-adaptive absorption tower

The strong mass transfer self-adaptive absorption tower comprises a tower body provided with a gas inlet and a gas outlet, and a liquid holding part and a spraying part which are sequentially arranged in the tower body along the flue gas trend, the liquid holding part comprises a regulating valve and a liquid holding tank arranged on the inner wall of the tower body, and the opening direction of the liquid holding tank directly faces the spraying direction of the spraying part. The spraying part is used for spraying absorption liquid and enabling the absorption liquid to react with flue gas entering the liquid holding layer, the liquid holding tank is used for receiving the absorption liquid sprayed by the spraying part, the regulating valve is arranged on the liquid holding tank and used for controlling the liquid level height of the liquid holding layer, and a stable and efficient liquid holding layer reaction area is formed; on the premise of realizing dual treatment of the liquid holding layer and the spr
