Abstract (en)
[origin: CN112325423A] The present invention provides a purification device with a heating filter for killing biological species including COVID-19. The device utilizes the supplied power to treat an air flow of an air treatment system of the facility. The frame has a plenum with an inlet and an outlet. The frame is configured to be positioned in an air flow of the air handling system to pass the air flow therethrough.A filter is disposed in the plenum and configured to filter the air flow therethrough up to a filter threshold. An ultraviolet light source disposed in the plenum is connected in electrical communication with the supplied power and is configured to generate ultraviolet radiation in the plenum. A permeable metal barrier disposed in the plenum is configured to obstruct air flow therethrough until anobstruction threshold. The barrier is connected in electrical communication to the supplied power and is heated to a surface temperature.
