Abstract

A silent type ozone generator using water surface has been studied and improved its ozone generation characteristics by the controlling the height of Taylor cone by installing a mesh electrode, a dielectric bed of glass beads in the just under th surface of the water. The current-voltage characteristics and characteristics of ozone generation quantity of the test system were investigated and discharge current oscillograms of the each cases of the mesh electrode and the beds were observed and compared each other to analyze the discharge conditions. The Taylor cone height could be the cause of the discharge bridge to decrease the ozone generation on the discharge spacing. In this study, the hight of Taylor cone could be reduced greatly by installing the mesh and the glass beads bed just under the water surface. Therefore a higher ozone generation also could be obtained.
