Title:
NONTHERMAL PLASMA AIR TREATMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO2004014439
Kind Code:
A3
Abstract:
A method and apparatus (10') for reducing air contamination using a contaminant adsorbent (22') to remove contaminants from air, and a nonthermal plasma (20') to desorb and oxidize or detoxify the contaminants. The adsorbent (22') may be comprised of a unique combination of a zeolite with a material having a high dielectric value. The power supply for the nonthermal plasma reactor (20') is designed to seek and operate at the system resonant frequency. In one embodiment, the adsorbent material (22') is separated from the nonthermal plasma reactor(20'). In this embodiment, heat is applied to the adsorbent material to thermally desorb contaminants during a desorption/regeneration phase. Air is recirculated within the system to move desorbed contaminants from the adsorbent material to the nonthermal plasma reactor for decomposition. The recirculating air repeatedly moves contaminants through the reactor until they are destroyed or the desorption/regeneration phase is complete.
