Abstract
A wet flue gas desulfurizer wherein sulfur dioxide is absorbed into a slurry and an oxygen-containing gas is blown into the slurry to oxidize sulfites present in the slurry is characterized in that a slurry oxidation tank is equipped with a return pipeline for returning a portion of the slurry to a position at or near the bottom of the slurry oxidation tank, and the oxygen-containing gas is blown in at the discharge end of the return pipeline so as to divide the oxygen-containing gas finely by the action of the slurry returned through the return pipeline.
Claims4
A wet flue gas desulfurizer wherein sulfur dioxide is absorbed into a slurry and an oxygen-containing gas is blown into the slurry to oxidize sulfites present in the slurry, said desulfurizer comprising a slurry oxidation tank equipped with a return pipeline loxated outside of the slurry oxidation tank for returning a portion of the slurry to a position in said slurry oxidation tank, and the oxygen-containing gas is blown in at a discharge end of said return pipeline so as to divide the oxygen-containing gas by the action of the slurry returned through said return pipeline and to simultaneously agitate the slurry.
