ABSTRACT:
An air purifier to improve air quality for breathing is disclosed. A magnetized torch module that passes a large air flow 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 kinds of microbes. The invention employs two torch modules which run alternately to generate non-thermal plasma for air treatment via both thermal
on-thermal processes. The air flow 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 closing and opening 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 a household air purifier, integrating it to a building HVAC system, and a hospital air disinfector and maintaining the air quality of the clean rooms.
