Desulfuration and dust-removal absorption tower with cyclone tray

The invention provides a desulfuration and dust-removal absorption tower with a cyclone tray, and belongs to the technical field of desulfuration. According to the desulfuration and dust-removal absorption tower with the cyclone tray, a cyclone device is arranged in the absorption tower in the gas flow direction and comprises the tray and a cyclone, a cylindrical through hole is formed in the center of the tray, and the cyclone is arranged in the through hole. The desulfuration and dust-removal absorption tower is characterized in that the cyclone device further comprises a gas exhausting cylinder, and the gas exhausting cylinder is coaxially connected with a gas cyclone. According to the desulfuration and dust-removal absorption tower with the cyclone tray, the gas-liquid contact area is large, and gas-liquid mass transferring strength is high.
