Desulfurization and dust removing spraying absorption tower

The utility model provides a desulfurization and dust removing spraying absorption tower. The desulfurization and dust removing spraying absorption tower is characterized in that a demister, a spraying layer and a rotational flow plate are mounted in a tower body in sequence from top to bottom, wherein a flue gas inlet is arranged on the tower body and located under the rotational flow plate; a slurry groove is formed under the flue gas inlet; the spraying layer comprises a horizontal supporting rod mounted on the tower body, a spraying pipe mounted on the supporting rod, and a lot of hollow tapered nozzles mounted on the spraying pipe; and the spraying pipe is connected with the slurry groove by a circulating pump. The desulfurization and dust removing spraying absorption tower has the beneficial effects that the structure is simple, the operation energy consumption of the system is low and the engineering investment cost is reduced; and the desulfurization and dust removing effect is good, the reaction speed is rapid and the desulfurization and dust removing spraying absorption tower is convenient for popularization and application.
