Effect of TiO2 and Reverse Air Supply on Ozone Production of Negative Corona Discharge with the Needle in the Dielectric Tube to Mesh Electrode System
Original language description
Ozone production using a hollow-needle-to-mesh negative corona discharge, with the needle electrode inserted in a dielectric tube, has been investigated. The air to the discharge could be supplied either through the needle electrode or reversely through the mesh electrode, which could additionally be covered with globules of TiO2 photocatalyst. The effects of these parameters on the electrical characteristics of the discharge, on ozone production and on the transition of the discharge from the glow to the streamer regime, have all been investigated. We found that reverse air supply substantially affects the electrical characteristics of the discharge when the needle electrode is inserted in the dielectric tube. Placement of TiO2 globules on the mesh decreases discharge voltage for a simple needle as well as for all positions of the needle inside the dielectric tube. The best performance from the standpoint of discharge ozone generation showed discharge with a supply of air through the needle electrode inserted in the dielectric tube with TiO2 globules on the mesh electrode.
