High-efficient granite desulfurizing tower

The utility model relates to a high-efficient granite desulfurization tower, comprising a desulfurization tower body. The desulfurization tower which is made of granite is internally provided with a fog dispersal system, a plurality of layers of spraying systems, a cyclone device and a pre-cool zone, manhole doors are arranged on the wall of the desulfurization tower body corresponding to the repair positions of the fog dispersal system, the spraying systems and the pre-cool zone; platforms and stairs are arranged outside the wall of the desulfurization tower body corresponding to the positions of the manhole doors of the fog dispersal system and the spraying systems; the pre-cool zone is fixedly connected with the desulfurization tower body in a way that a tangential line inclines downwards, and overflow ports are arranged at the bottom part of the desulfurization tower body. The high-efficient granite desulfurization tower has the advantages that a combined structure of pre-cool zone pre-spray treatment, la
