PLASMA AND PHOTOCATALYSIS HYBRID SYSTEM FOR ELIMINATING VOLATILE ORGANIC COMPOUNDS AND A BAD SMELL

摘要

A plasma/photocatalyst hybrid system capable of eliminating volatile organic compounds and odors of various concentrations and all types by disposing a photocatalyst in a post-treatment step after a low temperature plasma treatment step, and a method for eliminating volatile organic compounds and odors using the same are provided. In a plasma/photocatalyst hybrid system basically comprising a plurality of flat electrodes disposed in parallel, wherein an AC power source is connected to one flat electrode, and other flat electrode neighboring the one flat electrode is connected to an earth in a continuous and repeated manner, a plasma/photocatalyst hybrid system for eliminating volatile organic compounds and odors comprise: a low temperature plasma reactor for generating low temperature plasma by connecting two dielectric plates to both sides of a metal thin film in the respective flat electrodes; and a photocatalytic reactor comprising a photocatalyst coated honeycomb monolith or metal mesh-form support mounted perpendicularly to a flow of volatile organic compounds and odors, and ultraviolet lamps respectively installed in front and rear of the honeycomb monolith or the metal mesh-form support.
