Bubbling absorption tower for wet flue gas desulfurization

The invention discloses a bubbling absorption tower for wet flue gas desulfurization. According to the technical scheme, the bubbling absorption tower for wet flue gas desulfurization is characterized by comprising a tower body, a flue gas outlet arranged in the top of the tower body, and a flue gas inlet arranged in the middle of the tower body; the tower body is provided with an oxygenized air hole below the flue gas inlet, a demister, a bubbling desulfurization area and a spraying desulfurization area are arranged in the tower body sequentially from top to bottom, a spraying circulating component for primary desulfurization of flue gas is arranged in the spraying desulfurization area, and a bubbling component for secondary desulfurization of flue gas is arranged in the bubbling desulfurization area. Flue gas is pretreated via the spraying circulating component, the temperature and acidic matter content of the flue gas are decreased, and accordingly, scaling of the bubbling component is prevented and desulf
