Combined type air purification and sterilization device

A combined-typed air purification and sterilization device, is used in air purifying field. The invention consists of particle collecting component, ozone- photocatalysis, air and water departing component, water spray-air and water isolation component. Particle collecting component is installed in the front with ozone-light catalysis at its back and water spray-air and water isolation component at last, all of them are separate and parallel with each other, linking closed to air pipe all around, and all the air currents cross particle collecting component , ozone- photocatalysis and water spray- air and water isolation component. The invention combines water mist absorption technique with the photocatalysis and ozone technique, uses water mist to absorb organic pollutant and ozone gas remained and creates clean air. The invention has excellent sterilization ability and absorbing organic pollutant effect, especially suitable for air purification in room of central air conditioning system to eliminate cross transmission of infectious disease caused by using central air conditioning system effectively, and used as air humidifying and purifying device as well.
