ABSTRACT:
Gases that are to be scrubbed, particularly flue gases, pass through an inlet line (14) into a processing area (9) wherein the gases are exposed to the effects of a scrubbing agent that is contained in a bath (4). To this end, the liquid is sprayed by means of a rotating disc arrangement (17), the discs of which are coated--preferably through a hollow shaft (18)--with a layer of the scrubbing agent, this coating then being separated from the rotating discs as a result of centrifugal forces, with the attendant formation of an annular spray zone. The gas scrubber can trap sulfur dioxide that is contained in the flue gases. To this end, water is used as the scrubbing agent, and sodium carbonate (soda) is added to this. The sodium carbonate is converted with the water and with the carbon dioxide that is contained in the flue gas to hydrosodic carbonate, and this, together with the sulfur dioxide that is contained in the flue gas forms sodium sulfate if oxygen or additional air is introduced through the opening (26) into the processing area (9), and this sodium sulfate then collects on the bottom of the bath (4) in the form of a sediment.
