Abstract
The utility model discloses a flue gas desulfurization absorption tower, which comprises a tower body, as well as a stirrer, a nozzle and a demisting device which are arranged in the tower body. A flue gas inlet and a flue gas outlet are arranged on the tower body, wherein a spray layer is arranged between the flue gas inlet and the flue gas outlet; a gas flow distributing plate parallel to the cross section of the tower body is arranged between the flue gas inlet and the spray layer; and a plurality of through holes are distributed on the gas flow distributing plate. The absorption tower ensures that flue gas in the tower is uniformly distributed and increases the contact chances of SO2 and absorption liquid by setting the porous gas flow distributing plate parallel to the cross section of the tower body in the tower body, ensuring that the distribution of holes on the plate can guarantee the uniform passing of gas flow and ensuring that serous fluid after absorbing the SO2 can smoothly fall back to the bottom of the tower. Meanwhile, due to the presence of the porous gas flow distributing plate, the contact time of the SO2 and the absorption liquid can be prolonged, so as to guarantee the complete reaction of the SO2 and the absorption liquid and improve desulfurization efficiency.
