Abstract
An ion exchange scrubber has a housing, and a partition plate installed within the housing. The partition plate partitions an inner space of the housing in longitudinal direction into two chambers that are filled with a predetermined amount of aqueous solution. The upper end portions of the two partitioned chambers communicate with each other. At least one cartridge is installed at the upper portion and has an ion exchange resin. The ion exchange resin removes a harmful substance contained in the gas. By repeatedly pumping the aqueous solution from one side chamber to the other side chamber, and immersing and cleaning the contaminated ion exchange resin in the aqueous solution, the contaminated gas can be effectively processed even with a small amount of water.
