Abstract:
A photocatalytic reactor for the destruction of organic air-borne pollutants, the photoreactor comprising;means for admission of a gas stream carrying air-borne volatile organic pollutants into a closed tubing system; a Venturi section for constraining and increasing the velocity of the gas stream while simultaneously creating a suction effect to promote self-cleaning of said Venturi section by the removal of dust and dirt from the air stream and preventing dust and dirt to accumulate within said Venturi section; and means for irradiating the air-borne volatile organic pollutants within the gas stream; wherein said Venturi section comprises an elongate pipe having a convergent section, a straight section and a divergent section, said divergent section having a UV light illuminating means and a reflective means to direct reflected light onto the irradiating means.
