Title:
AIR STERILIZER AND PURIFIER
Document Type and Number:
WIPO Patent Application WO2017010839
Kind Code:
A1
Abstract:
The present invention provides an air sterilizer and purifier comprising: a dust filter; a photocatalytic tubular element which has a circular or right-angled cross-section of sintered glass beads having a diameter of 0.8-1.5 mm and has a surface coated with anatase titanium dioxide nanoparticle powder in a specific surface area in the range of 100-400 m2/g; and at least one UV lamp having radiation in the range of "A" (400-315 nm wavelength) to purify indoor air from organic, inorganic and biological contaminants such as molecular and aerosol hazardous chemicals, bad odors, allergens, viruses, bacteria and fungi. An electric filter is disposed before the photocatalytic element. The electric filter includes a wire corona electrode, and fixed and repulsive electrodes in groove shapes at a potential difference of 10-25 kV between the corona electrode and a dust collecting electrode and an electric field of 1-20 kV/cm between the dust collecting electrode and a repulsive electrode.
