Plasma Torch Implemented Air Purifier

Abstract

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. This invention is suitable for applications such as household air purifier, integrating it to building HVAC system, and hospital air disinfector and maintaining the air quality of the clean rooms.
