Document Type and Number:
Japanese Patent JP6853640
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for regenerating a photocatalyst deodorization material capable of efficiently, sufficiently regenerating a photocatalyst deodorization material whose performance is deteriorated by contamination by tobacco smoke or the like and the deposition of non-removed substance.SOLUTION: Provided is a method for regenerating a photocatalyst deodorization material used for air purification and whose performance is deteriorated by the deposition of non-removed substance, comprising: a cleaning step where a photocatalyst deodorization material using an acidic aqueous solution; and an irradiation step where the photocatalyst deodorization material after the cleaning is irradiated with light having a wavelength at which the photocatalyst is excited. Also provided is a photocatalyst deodorization material regeneration system comprising: a cleaning part where a photocatalyst deodorization material is cleaned using an acidic aqueous solution; and an irradiation part where the photocatalyst deodorization material after the cleaning is irradiated with light having a wavelength at which the photocatalyst is excited. Also provided is a method for producing a regenerated photocatalyst deodorization material comprising: a cleaning step where a photocatalyst deodorization material is cleaned using an acidic aqueous solution; and an irradiation step where the photocatalyst deodorization material after the cleaning is irradiated with light having a wavelength at which the photocatalyst is excited.SELECTED DRAWING: Figure 4
