To obtain a desulfurizer for stack gas capable of remarkably decreasing the pieces of pipelines equipped in an absorption column and attaining further simplification of the whole equipment.
In the desulfurizer for stack gas for performing the reaction and absorption of sulfur dioxide in a waste gas by forcibly feeding the waste gas while forcibly feeding a gas for oxidation into an absorbing solution stored in the absorption column to allow to gas-liquid contact, the absorbing solution and the air for oxidation are supplied to the absorption column through the same pipe line 28 used for each other by connecting a supply pipe 22 for replenishing the absorbing solution to the absorption column to a supply pipe 21, for forcibly supplying the gas for oxidation to the absorption column.
