Industrial dielectric barrier discharge plasma for odor control

This paper presents one industrial dielectric barrier discharge plasma technique for controlling odor gases emission. The cylinder type home-made ceramic dielectric insulator has outer and inner diameters of 100 mm and 80 mm, respectively. Its active plasma length is 800 mm. The plasmas are produced on both side of the ceramic tube by applying pulse AC voltage. The main specifications of peak-peak voltage, pulse duration, repetition frequency and average power are around 30−50 kV, 25 μs, 3−5 kHz and 50−100 kW, respectively. Typical industrial applications are related to food, municipal sewage, incineration power plant, and chemical industries for odor emission control.
