Efficient desulfurizing, dedusting and demisting spray tower

The utility model discloses an efficient desulfurizing, dedusting and demisting spray tower which is characterized in that the side wall of the spray tower is respectively provided with a flue gas inlet and a flue gas outlet, a plurality of spray layers are arranged in the spray tower, and a demister and a pore plate are also arranged in the spray tower; an upper manhole and a lower manhole are respectively formed in the spray tower. The number of the spraying layers is four, and the horizontal rotation angle between every two adjacent spraying layers is 30 degrees. And the layer flow of the spraying layer is 250m < 3 >/h. By arranging the pore plate, the smoke homogenizing effect can be achieved when the smoke passes through the pore plate, the reaction area with the smoke is increased, and the sulfur removal efficiency in the subsequent spraying process is improved. And four spraying layers are arranged, and the horizontal angle between every two adjacent spraying layers is set to be 30 degrees, so that the
