Abstract
A dielectric barrier discharge tube includes a quartz tube, the middle of the quartz tube is sleeved with a high-voltage electrode, an inner electrode is arranged in the quartz tube, a drive fan is arranged at the end of the inner electrode, a discharging needle set is arranged on the surface of the inner electrode, and a spiral discharging wire is suspended and arranged at the tip of the discharging needle set. After a high voltage electric field is applied to the high voltage electrode, the discharging needle set and the spiral discharging wire discharge, the discharging needle set and the spiral discharging wire discharge at different time points. When the gas passes through the driving fan, the flow direction of the gas is changed. A cyclone can be generated to drive the gas to flow towards the discharging area.
