  • Cyclone exchanger with tranquilizing tank and method for purifying and decontaminating air
    Patent number: 5968231
    Abstract: A device and a method for purifying and decontaminating air uses an exchanger of the cyclone type and furthermore employs a combination of the action of cyclonic centrifugation and the action of at least one path enhancing field. A tranquilizing chamber, which is separated from the cyclone exchanger by a vent, maintains a volume of liquid into which particles and droplets are received from the peripheral wall. To this end, particulates are partially electrified before entering the enhancing field.
