Description

Technical field:

[0001] The invention belongs to the technical field of ozone generators, and in particular relates to a discharge unit of an ozone generator and an ozone generator. Background technology:

[0002] Most of the existing ozone generator discharge units have double air gap discharge, including an outer electrode, an inner electrode and a glass tube between the inner and outer electrodes, wherein there is an annular gap between the inner electrode and the glass tube, and between the glass tube and the outer electrode.

[0003] In this technical solution, oxygen-containing gas enters the annular gap from one end of the discharge unit and performs air gap discharge under the action of a strong electric field. The oxygen in the oxygen-containing gas is ionized to generate ozone gas. The concentration of ozone in the output mixed gas is an important factor affecting the power consumption per kilogram of ozone produced.

[0004] At the same time, due to the instability of ozone, the generated ozone is easily decomposed and regenerated into oxygen, resulting in a low ozone concentration in the mixed gas output by the discharge unit in the air gap discharge ozone generator, low ozone yield, high power consumption per kilogram of ozone production, and high cost. For the performance evaluation of ozone generators, an important technical indicator is the power consumption per kilogram of ozone produced. The lower the power consumption, the lower the operating cost.

[0005] Therefore, there is a need for a discharge unit and an ozone generator having a high ozone concentration in the output gas and low power consumption per kilogram of ozone produced to meet actual needs. Summary of the invention:

[0006] One of the purposes of the present invention is to provide a discharge unit of an ozone generator having a high ozone concentration in the output gas and a low power consumption per kilogram of ozone produced, so as to overcome the shortcomings of the existing ozone generator having a low ozone concentration in the output gas and a high operating power consumption.

[0007] The technical solution for achieving the first object of the present invention is as follows: a discharge unit of an ozone generator, comprising an inner electrode, an outer electrode and a dielectric tube, wherein the inner electrode is in the dielectric tube, and the dielectric tube is in the outer electrode, characterized in that: the inner electrode comprises a core tube and a conductive wire mesh, the conductive wire mesh is coated on the outer surface of the core tube, there is an annular gap between the outer surface of the conductive wire mesh and the dielectric tube, and there is a gap between the outer electrode and the dielectric tube.

[0008] For better technical effects, the technical features of the present invention may also be specifically the following technical features:

[0009] 1. The inner surface of the conductive wire mesh is in close contact with the outer surface of the core tube.

[0010] 2. The conductive wire mesh is in a sleeve shape.

[0011] 3. Furthermore, the conductive wire mesh is single-layered.

[0012] 4. The conductive mesh is elastic.

[0013] 5. The conductive wire mesh is made of conductive material, such as conductive metal.

[0014] 6. The conductive wire mesh is made of one or more of stainless steel, titanium, chromium, aluminum, copper, silver or alloy materials.

[0015] 7. The annular gap between the outer surface of the conductive wire mesh and the dielectric tube is uniform.

[0016] 8. The outer surface of the conductive wire mesh of the inner electrode and the dielectric tube are supported by a spiral support device.

[0017] A second object of the present invention is to provide an ozone generator having a high ozone concentration in the output gas and low power consumption per kilogram of ozone produced.

[0018] The technical solution of the ozone generator of the second purpose of the present invention is as follows: an ozone generator, comprising a plurality of discharge units, characterized in that: the discharge units are the discharge units described in the technical solution of the first purpose of the present invention.

[0019] The ozone discharge unit and ozone generator using the technical solution of the present invention have the following advantages:

[0022] 3. The ozone concentration in the mixed gas output by the ozone generator is high.
