Ozone generation apparatus
View Patent ↗In an ozone generation apparatus, a discharge cell includes a first electrode part, a second electrode part, and a dielectric partition plate. The first electrode part and the second electrode part face each other, and the dielectric partition plate is provided between the first and second electrode parts.
1. An ozone generation apparatus that includes a discharge cell in which a dielectric barrier discharge is generated to generate ozone using said dielectric barrier discharge, said discharge cell comprises:
a first electrode part;
a second electrode part being disposed to face said first electrode part to form a space; and
a dielectric partition plate being provided between said first electrode part and said second electrode part to separate said space as two discharge spaces, the two discharge spaces including a first discharge space formed between the first electrode part and the dielectric partition plate, and a second discharge space formed between the second electrode part and the dielectric partition plate, wherein
each of said first electrode part, said second electrode part, and said dielectric partition plate has a flat plate shape, and
spacers for forming said two discharge spaces are integrally formed on said dielectric partition plate, said spacers keep a gap length in each of said two discharge spaces constant,
wherein the gap length in each of the two discharge spaces is smaller than a thickness of the dielectric partition plate.
2. The ozone generation apparatus according to claim 1 , wherein
said dielectric partition plate is a net plate.
3. The ozone generation apparatus according to claim 1 , wherein
said spacers include a plurality of spacers.
4. The ozone generation apparatus according to claim 3 , wherein
said spacers are radially disposed on said dielectric partition plate.
5. The ozone generation apparatus according to claim 1 , wherein
a photocatalytic material is formed on said first electrode part facing said first discharge space, said dielectric partition plate facing said first discharge space, and said second electrode part facing said second discharge space.
6. The ozone generation apparatus according to claim 1 , wherein
a metal or a metal oxide is formed on said first electrode part facing said first discharge space, said dielectric partition plate facing said first discharge space, and said second electrode part facing said second discharge space.
7. The ozone generation apparatus according to claim 1 , wherein the gap length in each of the discharge spaces is less than 40% the thickness of the dielectric partition plate.
