When the incinerator is used for incinerating organic domestic garbage, a large amount of tail gas is generated, the tail gas contains a large amount of sulfur dioxide, and the sulfur dioxide is discharged into the air to inevitably affect the surrounding air environment and generate acid rain. Therefore, before the tail gas is discharged, the absorption tower is used for absorbing the sulfur dioxide in the tail gas. The during operation will burn in the tower body that the tub inserts the absorption tower is gone into to the exhaust pipe of burning furnace, spraying system blowout chemical agent in the tower body afterwards, and the chemical agent that sprays down absorbs sulfur dioxide to the desulfurization treatment to tail gas has been realized. However, the chemical agents sprayed from the spraying system are in a dispersed state, and the flow speed of the tail gas entering the tower body is high, so that the chemical agents do not fully contact with the sulfur dioxide in the tail gas, and further the spraying treatment is required for a long time to completely absorb the sulfur dioxide, which undoubtedly reduces the treatment efficiency of the sulfur dioxide. In addition, the sprayed chemical agent cannot be reused to continue spraying, so that the waste of the chemical agent is caused, and the treatment cost of the sulfur dioxide is increased.
