Study of Exhaust Air Treatment From a Ship Building Factory Painting Facility Using Pulse Plasma Technology

Ship building companies are exposed to increasingly strict regulations on exhaust air from painting facilities, which current exhaust air treatment methods cannot adequately meet. We propose the use of a plasma system using a pulsed-power supply, which we constructed and tested at the painting facility of a ship building factory. Through gas chromatography and facility efficiency analysis, we found flexibility in design of the plasma system. We demonstrate the efficiency and safety of our plasma system, and emphasize the importance of posttreatment facilities for the secondary pollutant treatment.
