Abstract

PURPOSE: To achieve effective sterilization of microbes in air, by a method wherein ultraviolet is radiated to generate ozone and sterilize microbe and at the same time sterilized microbe-contg. fine particles are treated to carry electric charge, and then the electrically charged particles and remaining ozone as well are removed simultaneously.
CONSTITUTION: An ultraviolet radiating part, a sterilizing part, an electric field, a photoelectron emitting part, a remaining ozone removing part, and an electrically charged particle collecting part are composed of mainly an electrode 20, a metal surface 21 from which photoelectrons are emitted, an ultraviolet lump 22, a remaining ozone removal filter 23, and an electrically charged particle collecting filter 24. By using the apparatus, ozone is generated by ultraviolet radiation and microbes are sterilized. At the same time, sterilized microbe- contg. fine particles are treated to carry electric charge and then the electrically charged fine particles are remaining ozone as well are removed. As a result, microbes in air are sterilized and removed efficiently.
