    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. At least one gas inlet hole is formed in an external plate of the chamber at position below the position where the cartridge is installed. At least one gas inlet tube is connected with the gas inlet hole. A gas exhaust hole is formed in an upper plate of the housing. At least one introduction/exhaustion hole is formed at a lower portion of the chamber, for supplying or exhausting the aqueous solution. At least one connection tube connects the introduction/exhaustion holes with each other. At least one level control valve is installed in the at least one connection tube. 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.
