UV lamp device for air cleaning
A method for fabricating a UV lamp for treating waste gas and for treating waste gases therewith is provided which is designed and fabricated based on solgel coating techniques. A sol of photo-catalytic materials comprising anatase TiO2 as the main component, and/or other semiconductive components such as WO3, AnO, SnO2, or Fe2O3, coated on a glass-fiber-cloth. Then, the cloth is impregnated with an oxidation catalyst of precious metal such as Pd, Au, Pr or Ag, or a transition metal oxide of Mo, Nb, V, Ce or Cr. The impregnated cloth is then wrapped on a UV lamp tube. The UV lamp treats waste gas by irradiating the UV light therefrom onto the surface of the 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.
