AIR CLEANING SYSTEM HAVING FUNCTION OF REGENERATING PHOTOCATALYST RESPONSIVE TO VISIBLE LIGHT

摘要

Disclosed is an air cleaning system using a photocatalyst responsive to visible light. The present invention relates to a method for regenerating a photocatalyst by completely regenerating the photocatalyst contaminated after a photocatalytic reaction to a photocatalyst responsive to visible light by high temperature heating such that the photocatalyst is reusable. The present invention also relates to an air cleaning system using a filter for use in high-temperature coated with a photocatalyst, the filter having the device generated by the abovementioned method. The air cleaning system is configured to serve as a filter having a photocatalyst regenerating ability, in which the filter is moved to a heating chamber and regenerated at a high temperature based on the contaminated condition thereof so as to regenerate the visible light responsiveness of the photocatalyst.
