Patent number: 8703049Abstract: An apparatus and a method for purifying and heating air using photocatalytic oxidation. The apparatus includes a housing, a heater, and a photocatalytic oxidation unit disposed within the housing. The housing defines a flow path for air to move through the apparatus such that air from the environment is drawn into the apparatus and passes over the photocatalytic oxidation unit. A pollutant in the air from the environment adsorbs to a surface of the photocatalytic material coating the plates, and the surface of the photocatalytic material is exposed to ultraviolet light generated by the ultraviolet light source. The energy of the ultraviolet light activates the photocatalytic material, which then breaks down the pollutant leaving non-toxic components and purified air. The air then passes over the heater and back into the environment. A fan is also included to move air through the flow path.Type: GrantFiled: May 27, 2009Date of Patent: April 22, 2014Assignee: Marley Engineered Products LLCInventors: Frank Lockhart, Timothy Matt, Joseph DeAngelis, Dennis Neibrook

Publication number: 20090288559Abstract: An air purifier to improve air quality for breathing is invented. A magnetized torch module that passes a large airflow is designed. The emission spectroscopy of the torch indicates that the plasma effluent carries an abundance of reactive atomic oxygen (RAO), which can effectively kill all kind microbes. The invention employs two torch modules which run alternately to generate non-thermal plasma for air treatment via both thermal/non-thermal processes. The airflow through the on-torch module is mainly treated thermally. A controlling air valve is designed to direct the exiting airflow of the off-torch module to pass through the plasma torch of the on-torch module for non-thermal treatment. The controlling air valve also works to turn the torch modules on and off synchronizing with the close and open of the two air valves in the controlling air valve. This device purifies ambient air in a fast rate and kills microbes thoroughly.Type: ApplicationFiled: May 24, 2008Publication date: November 26, 2009Inventor: Spencer P. Kuo
