Abstract

This invention relates to a method and a device for ozone production, in particular to produce ozone by synergism of discharge and catalyst. The method includes introducing air or oxygen into the discharge space between high voltage electrode and grounding electrode, and discharging, wherein catalysts with high surface area and dielectric property filled in the space has catalytic effect on ozone production. The device comprises a discharge electrode consisting of high voltage power and high voltage electrode and grounding electrode, a cavity and an outlet and an inlet thereon, catalysts (2) with high surface area and dielectric property composited between the high voltage electrode (3) and the grounding electrode (4), spaces between discharge electrode and catalysts (2) and spaces formed by catalysts (2) as flow channel for discharge gas.

Description

technical field [0001] The invention relates to an ozone generating method and an ozone generating device, in particular to an ozone generating device with synergistic effects of a discharge and a catalyst, and belongs to the technical field of ozone generating equipment manufacturing. Background technique [0002] Ozone has a very strong oxidation ability (redox potential 2.07V), slightly inferior to fluorine (2.87V), higher than chlorine (1.36V). Ozone decomposes into oxygen after tens of minutes, no secondary pollution, and no residue. Ozone is a strong oxidant, bactericidal disinfectant, catalyst, decolorizer and deodorant, and has a wide range of applications. It can be applied to water supply sterilization and disinfection treatment (there is no residual methylhalogen THM and organic chloride carcinogens after chlorine treatment); advanced treatment of sewage and its recycling; bleaching of paper pulp without chlorination treatment; purification of aquaculture pond wa...
