Claims
- 1. A device for purifying and decontaminating air comprising a cyclone exchanger having means for causing cyclonic centrifugation of the air in combination with means for exposing the air to at least one cyclone path enhancing field, wherein the air is partially electrified before entering the enhancing field, wherein the cyclone exchanger has cooling means coupled to a peripheral wall of the cyclone exchanger, wherein the enhancing field operates to direct the partially electrified air radially outwardly toward the peripheral wall of the cyclone exchanger, and further comprising a tranquilizing chamber separated from the cyclone exchanger by a vent and adapted to maintain a volume of liquid into which particles and droplets are received from the peripheral wall.
- 2. The device of claim 1 wherein the enhancing field is an axial magnetic field.
- 3. The device of claim 2 which further includes a plurality of electrically conducting turns for receiving a continuous current so that the axial magnetic field is induced in the conducting turns.
- 4. The device of claim 2 wherein the enhancing field further includes a radial electric field in combination with the axial magnetic field.
- 5. The device of claim 1 wherein the enhancing field is a radial electric field.
- 6. The device of claim 5 which further includes a plurality of polarized plates for developing a centripetal electric field between an inner wall of the cyclone exchanger and the peripheral wall.
- 7. The device of claim 1 which further includes an axial ionizer located at an inlet of the cyclone exchanger, for electrifying the air entering the inlet.
- 8. The device of claim 7 wherein the inlet includes a heated central filament and a cylindrical collector casing.
- 9. The device of claim 1 wherein the cooling means is a coolant fluid circulating through a coil which operates as a condenser, thereby causing a trickle of water droplets which effects a dual role of particle trapping and self-cleaning of the cyclone exchanger.
- 10. The device of claim 1 which further includes a deflector for directing scrubbed air to an outlet vortex of the cyclone exchanger.
- 11. A method for purifying and decontaminating air in a cyclone exchanger including cooling means coupled to a peripheral wall of the cyclone exchanger, and means for causing cyclonic centrifugation of the air, the method comprising the steps of partially electrifying the air, and exposing the partially electrified air to at least one cyclone path enhancing field in combination with the cyclonic centrifugation, wherein the enhancing field operates to direct the partially electrified air radially outwardly toward the peripheral wall of the cyclone exchanger, on which droplets form carrying particles into a tranquilizing chamber separated from the cyclone exchanger by a vent and adapted to maintain a volume of liquid into which the particles and droplets are received from the peripheral wall.
- 12. The method claim 11 wherein the enhancing field is an axial magnetic field.
- 13. The method of claim 12 wherein the enhancing field further includes a radial electric field in combination with the axial magnetic field.
- 14. The method of claim 11 wherein the enhancing field is a radial electric field.
- 15. The method of claim 11 which further includes the step of electrifying the air in an axial ionizer located at an inlet of the cyclone exchanger.
- 16. The method of claim 11 wherein the cooling means operates as a condenser, causing a trickle of water droplets which effects a dual role of particle trapping and self-cleaning of the cyclone exchanger.
