Abstract: The plasma rail device of the invention is a novel method and device to generate plasma right at the surface or slight above the surface for surface treatment, specifically for surface sanitization. The device generally comprises pairs of electrodes held together by a frame. The device features a fame that holds and positions the electrodes in a close proximity towards the surface under treatment. Discharges are created in the space bounded by the electrodes to generate plasma on the surface and above the surface for treatment so that the device can be positioned outside the object under treatment.

Abstract: The Diffusive Plasma is for effective treatment of contaminated air and material processing. Air is purified and disinfected by passing through the diffusive plasma device which includes a reactor or a plurality of reactors arranged in parallel or series and is energized by a high voltage alternating current power supply. The diffuser, being electrically isolated, provides extra nucleation sites to initiate discharges. It serves to improve the generation of uniform and consistent plasma and to reduce the variation of discharge properties among the reactors. The addition of a diffuser, thereby, enhances the overall effectiveness of decomposing chemicals and destroying microbes to achieve high air treatment and material processing performance. The diffuser can be made of suitable filtering materials to additionally serve as a filter.

Abstract: An apparatus for air purification and disinfection is provided. The apparatus includes at least one elongated reactor having an elongated inner electrode and an elongated outer electrode. The outer electrode encompasses at least a portion of the inner electrode along a longitudinal axis of the reactor. The outer and inner electrodes are positioned in a substantially concentric relationship and define a reaction chamber therebetween. The apparatus also includes an inner electrode mounting member holding the inner electrode at an end of the inner electrode and an outer electrode mounting member holding the outer electrode at an end of the outer electrode. The apparatus further includes a power supply adapted to supplying electrical power to the inner and outer electrodes to generate plasma within the reaction chamber to purify and disinfect air flowing therethrough.
