Method of making UV lamp for air cleaning
First Claim
1. A method for fabricating a UV lamp for treating waste gases, comprising the steps of:
- (a) formulating a photocatalyst coating sol;
(b) dip coating a glass fiber cloth with said photocatalyst sol;
(c) drying and sintering into a coating having a photocatalytic function;
(d) impregnating said photocatalyst-coated glass fiber cloth with a solution of an oxidation catalyst;
(e) drying again to form a photocatalyst-coated glass fiber cloth; and
,(f) wrapping around a UV lamp with said photocatalyst-coated glass fiber cloth, wherein depending on the shape of the UV lamp tube, said photocatalyst-coated glass fiber cloth wrap tightly and be fixed around said UV lamp tube, or said photocatalyst-coated glass fiber cloth can be tailored into a sleeve or box and then cover on said UV lamp tube.

Abstract
The invention relates to a method for fabricating a UV lamp for treating waste gas and to a UV lamp for treating waste gases fabricated therefrom, which is designed and fabricated based on solgel coating techniques by coating a sol of photocatalytic materials comprising anatasse TiO2 as the main component, and/or other semi-conductive components such as WO3, ZnO, SnO2, or Fe2 O3, on a glass-fiber-cloth, and/or then impregnate this cloth with oxidation catalyst of precious metal such as Pd, Au, Pt or Ag, or transition metal oxide about Mo, Nb, B, Ce or Cr, and then wrap this cloth on a UV lamp. The invention relates also to a process for treating waste gases by using said UV lamp for treating waste gas through irradiating UV light therefrom on the surface of such photocatalytic materials to generate free electron and electron hole pairs which can decompose waste gases such as organic or inorganic pollutants in the air into unharmful gases.
