<p>PROBLEM TO BE SOLVED: To obtain a wet type stack gas desulfurizing apparatus with a low operation cost by suppressing sucking bubbles into a circulation pump to prevent the deterioration of desulfurization performance without increasing equipment cost sharply. SOLUTION: A baffle plate 15 having a upper end projected up to the liquid level and provided with an absorbing liquid circulation opening part between the lower end part and the bottom surface of a circulation tank 6 is mounted at the vicinity of a suction pipe line 14 of the absorbing liquid circulation pump 4 provided on the wall surface of the circulation tank 6 to divide the tank into 2 zones and air is blown into an absorbing liquid 5 in an oxidation zone side in the divided two zones in the circulation tank 6, where the suction pipe line 14 is not present, through an air blow pipe line 8, liquid drops falling down into the absorbing liquid 5 in the non-oxidation zone in the circulation tank 6, where the suction pipe line 14 is present, are recovered in a upper part space in the non-oxidation zone and all of the recovered absorbing liquid 5 is fed to the oxidation zone side.</p> |
