Abstract:
Photocatalyst dispersion and a manufacturing method thereof are provided to prevent solid-liquid separation of photocatalysis oxidation tungsten particles and titanium oxide photocatalyst particles and to form a photocatalyst coated film having high photocatalytic activity. Photocatalyst dispersion is gained by dispersing photocatalytic titanium oxide particles and photocatalytic tungsten oxide particles in a dispersion medium. A method for manufacturing photocatalyst dispersion comprises a step for dispersing photocatalytic titanium oxide particles in a solution in which a surface treating agent is dissolved and a step for mixing the photocatalytic tungsten oxide particles and a photocatalytic titanium oxide particle-dispersed solution.
Abstract:
The present invention relates to an air cleaner system having a function of regenerating a visible ray responding type photocatalyst and, more specifically, to a regeneration method capable of reusing a visible ray responding type photocatalyst by heating in high temperatures when the photocatalyst is contaminated after a reaction, and an air cleaner system using a high temperature filter coated with a photocatalyst having a device recycled by the same method. In accordance with the contamination status, the photocatalyst is transferred to a heating chamber and is regenerated in high temperatures to restore visible ray respondence and have a circulation ability to perform as a filter having regeneration ability of the photocatalyst. Therefore, the present invention relates to an air cleaner system having a photocatalyst application function having the regeneration function of a visible ray responding type photocatalyst.
Abstract:
The present invention relates to a fluid purification device using a ultraviolet ray emitting diode which comprises the following: an outer case; a fluid purification filter filtering inflowing fluid by being stored inside the outer case; a light catalyst coated on the surface of the fluid purification filter; and a light source unit mounted on the outer case to face the rear side of the fluid purification filter based on the inflow direction of the fluid, for emitting light in multiple wavelengths to the rear side of the fluid purification filter. The fluid purification device of the present invention emits light in multiple wavelengths for offering excellent sterilization and deodorization effects, and improves a regeneration efficiency of the filter by using the filter coated with the light catalyst for semi-permanently using the filter and improving the purification efficiency of the fluid.
