Title:
AIR CLEANING DEVICE AND AIR CLEANING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/218689
Kind Code:
A1
Abstract:
Provided is an air cleaning device that is capable of more reliably breaking down organic matter included in air. An air cleaning device (1) comprises: a thin plate parallel arrangement part (20) which has a plurality of thin plates (21) provided in parallel with spaces therebetween and has a coating layer on the front and rear surfaces of the thin plates (21); and an ultraviolet radiator (35) which radiates ultraviolet light onto the coating layer. The coating layer is configured as a metal-substituted hydroxyapatite layer in which a portion of the calcium in calcium hydroxyapatite is substituted with a metal selected from titanium, zirconium, iron, and tungsten.
