Development and Experimental Analysis of a New “Serpentine-Shape” Surface-DBD Ozone Generator—Comparison with a Cylindrical Volume-DBD Ozone Generator

Résumé

Ozone generators used in the industry for water treatment are almost all based on volume dielectric barrier discharge (DBD). The generation of ozone by surface DBD is also possible. However, there are not enough studies devoted to this solution. The objective of this article is the development of a new patent-pending “serpentine” model in which the gas circulates in a channel having the shape of a serpentine. The developed model is made of 10 parallel channels engraved in a Bakelite plate of 4-mm thickness. The ground electrode is an adhesive aluminum tape placed on the lower surface of the plate, while the high voltage electrode is constituted of narrow tapes of 1-mm width of the same material, placed in the bottom of each channel. The surface DBD is produced inside each channel that measures 1-cm width, 3-mm depth, and 10-cm length. The obtained results showed that the ozone rate (in g/hr) is much higher in the case of surface DBD compared to a cylindrical volume-DBD generator, which is the most used reactor in ozone technology. Furthermore, the energy efficiency of the “serpentine” model is better than the cylindrical model.
