Abstract
An ozone beam generation apparatus includes an ozonizer for forming an ozone-containing gas through the ozonization of an oxygen-containing gas; a refrigerator for liquefying or solidifying only ozone present in the ozone-containing gas; a vessel for storing the liquefied or solidified ozone; a temperature controller for contorting the temperature of the storing vessel and for gasifying the liquefied or solidified ozone; and a piping system for transporting-the gasified ozone to a desired device. The apparatus makes it possible to steadily and safely supply pure ozone to an apparatus for oxidation treatment.
