Abstract

The invention relates to an earth electrode wind-cooling flat-plate ozone generating unit, and belongs to the technical field of application of gas ionization discharge, plasma chemistry, environmental engineering and the like. The earth electrode wind-cooling flat-plate ozone generating unit is characterized in that both an earth electrode and a discharge electrode are in a rectangular flat-plate mode; the earth electrode and a cooling fin on the rear side are made of the same metal such as composite steel aluminum, stainless steel and titanium; a dense ionization discharge electric field is formed in a narrow gap between the discharge electrode and the wind-cooling earth electrode, and the electric field strength reaches between 100 and 400 kilovolts per centimeter; and electric field parameters are adopted to adjust and control oxygen molecule dissociation, and oxygen atoms, oxygen atom ions and the free radical concentration are generated by dissociative ionization reaction, so that the ozone production quantity and the ozone concentration are controlled, the redecomposition of controllable ozone is realized, and the ozone concentration reaches between 80 and 160 milligrams per liter. The earth electrode wind-cooling flat-plate ozone generating unit has the advantages of using wind cooling to replace water cooling or oil cooling, using the flat-plate ozone generating unit to replace a tube-type ozone generating unit, realizing the wind-cooling flat-plate small ozone generating unit, and highly efficiently generating ozone with high concentration and large production quantity.

Description

technical field

[0001] The invention belongs to the fields of gas discharge physics, atmospheric pressure plasma physics and the like, and relates to a ground electrode air-cooled flat-plate ozone generating unit. Background technique

[0002] There are many kinds of existing ozone generating methods or devices, most of which use water to cool the grounding electrode, while the Japanese flat Otto~plate type ozone generating device uses insulating oil to cool the discharge electrode and the grounding electrode to suppress the temperature rise of the gas in the discharge gap. In order to produce high-concentration ozone and reduce its decomposition.

[0003] However, due to the restriction of the glass manufacturing industry level, it is difficult to obtain a glass dielectric sheet with high flatness and high precision thickness. Due to the poor mechanical strength of glass, it is easy to break. A bigger problem is that due to the poor frequency characteristics of the glass ...
