Ozone generating unit and ozone generator

Abstract

The invention discloses an ozone generating unit and an ozone generator. The ozone generating unit comprises a high-voltage electrode, a ground electrode and a dielectric pipe. The dielectric pipe is inserted in the ground electrode, such that a first discharging air gap is formed. The high-voltage electrode is inserted in the dielectric pipe, such that a second discharging air gap is formed. A spiral supporting apparatus is arranged on the high-voltage electrode. The high-voltage electrode is arranged in the dielectric pipe through the spiral supporting apparatus. With the spiral supporting apparatus, the high-voltage electrode can be supported in the dielectric pipe, such that relatively high concentricity can be ensured; also, air flow can be uniformly distributed on the surface of the high-voltage electrode under guidance, such that uniform discharging and heat dissipating can be carried out. With the spiral supporting apparatus, dependence of the ozone generating unit on air gap uniformity and processing precision can be reduced. Therefore, under a condition of an existing processing precision, energy consumption of the ozone generator is reduced, ozone concentration is improved, and equipment reliability is improved.

Description

technical field [0001] The invention belongs to the technical field of ozone preparation, and in particular relates to an ozone generating unit and an ozone generator using the unit. Background technique [0002] Ozone is a strong oxidant that has the functions of decolorization, oxidation, sterilization and deodorization.
