Publication number: 20220217833Abstract: 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.Type: ApplicationFiled: May 5, 2020Publication date: July 7, 2022Applicant: ALPHATECH INTERNATIONAL LIMITEDInventor: Herman Yik Wai TSUI

Publication number: 20190287763Abstract: 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.Type: ApplicationFiled: March 16, 2018Publication date: September 19, 2019Applicant: ALPHATECH INTERNATIONAL LIMITEDInventor: Herman Yik Wai TSUI
