Air purification apparatus and method of forming the same

摘要

A photocatalytic air purification apparatus and method of fabricating the same. The apparatus may be configured to include a light source surrounded by one or more porous plate substrates. An inner and outer surface of each plate substrate may be coated with a photocatalyst material. The light source may be placed in a direction parallel to the direction of an air flow and in optical proximity to the plate substrates in order to activate the photocatalyst coating. The photocatalyst coating associated with the plate substrates may be activated by absorbing light with a wavelength shorter than a cut-off activation wavelength from the light source in order to capture and decompose organic components and airborne pollutants in the air by the activated photocatalyst.

1. An air purification apparatus, comprising:
a plurality of plate substrates each having an inner surface and an outer surface, wherein said inner and outer surfaces are coated with a photocatalyst and wherein said plurality of plate substrates possess a relatively high transmittance with respect to a wavelength range for activating said photocatalyst wherein a total number of said plurality of plate substrates is dependent on said transmittance; an adjustable interval between each of said plurality adjacent plate substrates; a light source surrounded by said plurality of plate substrates and located in a direction parallel to a direction of air flow, wherein said plurality of plate substrates absorbs a light energy with a wavelength shorter than a cut-off activation wavelength to activate said photocatalyst and thereby improve a usage efficiency of said light energy and an air purification efficiency for purification of air by said apparatus; a fixture associated with a plurality of fixture buckle for mounting said plurality of plate substrates and said light source; and a channel formed from and located at a base of said fixture providing an electrical circuit connection to said light source.
