[Abstract]:Glass beads, high alumina porcelain, quartz sand and fused quartz sand were filled in the discharge gap of DBD ozone generator with coaxial single medium and double water cooling structure respectively.The effect of gap width and other parameters on ozone formation efficiency.The results show that the dielectric constant of granular material is the main factor affecting the effect of ozone preparation. With the increase of dielectric constant, the gap breakdown voltage decreases, but because of the distortion of electric field caused by particles, the gap break field strength increases.The maximum energy efficiency of ozone formation is reduced and the saturation concentration is increased. The highest ozone saturation concentration is found in high alumina ceramics. Compared with unfilled empty bed, the saturation concentration increases by 136 percent. For filling molten quartz sand with different particle sizes, the saturation concentration increases with the increase of particle size.With the increase of gap breakdown voltage, the reduced field strength of gap increases, the maximum energy efficiency of ozone generation decreases, and the saturation concentration increases. By filling medium particles in wide gap, the effect of ozone production with narrow gap width can be obtained.
