Efficiency of Removing Sulfur Dioxide in the Air by Non-Thermal Plasma Along with the Application of the Magnetic Field

Abstract
The non-thermal plasma created by high voltage pulsed power supply can be usedto remove sulfur dioxide in the air, but how to increase the removing efficiency is not clear. It isnovel to apply the magnetic field in removing SO2 as discussed in this paper. The mechanismsof removing sulfur dioxide by non-thermal plasma along with the application of the magneticfield are analyzed, and the related factors affecting the removal efficiency, such as the magnitudeof pulsed voltage, the polarity of the pulse, the layout of the discharge electrode, especially themagnetic field are experimentally investigated. It can be concluded that the purification efficiencyis improved significantly by applying the magnetic field.
