Abstract
Description
Technical field:
[0001] The invention belongs to the technical field of ozone generators, and in particular relates to an ozone discharge unit and an ozone generator. Background technology:
[0002] Most of the existing ozone generator discharge units are double air gap discharges, including an outer electrode, an inner electrode and a dielectric tube located between the inner and outer electrodes. An annular gap is formed between the inner electrode and the dielectric tube, and between the dielectric tube and the outer electrode, respectively.
[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, an ozone discharge unit and an ozone generator with high output ozone concentration and low power consumption per kilogram of ozone produced are needed to meet actual needs. Summary of the invention:
[0006] One of the purposes of the present invention is to provide an ozone discharge unit with high ozone concentration in the output gas and low power consumption per kilogram of ozone produced, so as to overcome the shortcomings of the existing ozone generator with low ozone concentration in the output gas and high operating power consumption.
[0007] One of the technical solutions for achieving the first objective is as follows: an ozone discharge unit, comprising an inner electrode 1, an outer electrode 2 and a dielectric tube 3, wherein the inner electrode 1 is located in the dielectric tube 3, and the dielectric tube 3 is located in the outer electrode 2, characterized in that the outer surface of the inner electrode 1 has a concave-convex texture, and an annular gap is provided between the outer surface of the inner electrode 1 and the dielectric tube 3.
[0008] For better technical effects, the technical solution of the first objective of the present invention can also be specifically characterized by the following technical features:
[0009] 1. The concavo-convex texture is a raised texture 11, the top of the raised texture 11 is slightly higher than the root thereof, and the height of the raised texture 11 on the outer surface of the same inner electrode 1 is the same.
[0010] 2. The raised texture 11 is a combination of one or more of a lattice shape, a grid shape, a corrugated shape, a columnar dot shape, a spiral shape, and a corrugated shape.
[0011] 3. The raised textures 11 are evenly distributed on the outer surface of the inner electrode 1 .
[0012] 4. Furthermore, the raised textures 11 are regularly and evenly distributed on the outer surface of the inner electrode 1 .
[0013] 5. The annular gap between the outer surface of the inner electrode and the medium tube 3 is uniform.
[0014] 6. The height of the raised texture 11 is between 0.1-1 mm.
[0015] 7. The height of the raised texture 11 is between 0.15-0.75 mm.
[0016] 8. The inner electrode 1 and the medium tube 3 are supported by a spiral support device 5.
[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 for achieving 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:
[0020] 1. In the discharge unit of the present invention, surface discharge occurs on the concave-convex textured surface of the inner electrode, which can increase the concentration of ozone in the mixed gas output by the ozone discharge unit and improve the ozone production rate of the ozone generator.
[0021] 2. The ozone generator using the discharge unit of the present invention consumes low power per kilogram of ozone produced, has low operating electricity cost, and is energy-saving.
[0022] 3. The ozone concentration in the mixed gas output by the ozone generator is high. Under the condition of requiring the same ozone output, the ozone generator of the present invention can reduce the number of ozone discharge units, reduce hardware investment, and save costs.

[0027] 11 is the texture and 5 is the supporting device. Specific implementation method:
[0028] The following is combined with Figure 1-3 A first embodiment of the ozone discharge unit of the present invention is described in detail.
[0029] like Figure 1-3 As shown, an ozone discharge unit according to the first object of the present invention comprises an inner electrode 1, an outer electrode 2 and a dielectric tube 3, wherein the inner electrode 1 is in the dielectric tube 3, and the dielectric tube 3 is in the outer electrode 2, characterized in that: the outer surface of the inner electrode 1 has a concave-convex texture, and there is an annular gap between the outer surface of the inner electrode 1 and the dielectric tube 3. The top of the convex texture 11 is slightly higher than the root of the convex texture 11, and the height of the texture 11 on the outer surface of the same inner electrode 1 is the same.
[0030] Preferably, in this embodiment, the raised texture 11 is in the form of a raised grid and is evenly distributed on the outer surface of the inner electrode 1, such as Figure 2 shown.
[0031] Preferably, the annular gap between the outer surface of the inner electrode and the medium pipe 3 is uniform.
[0032] Preferably, the height of the raised texture 11 is between 0.1 and 1 mm.
[0033] Preferably, the height of the raised texture 11 is between 0.15 and 0.75 mm.
[0034] The raised texture 11 can be a combination of one or more of a dot matrix, a grid, a corrugated shape, a columnar dot shape, a spiral shape, a corrugated shape, or other textures that can generate surface discharge and help improve the discharge efficiency of the discharge unit. The raised texture 11 is regularly and evenly distributed on the outer surface of the inner electrode 1.
[0035] The raised texture on the outer surface of the inner electrode 1 can be formed by engraving, casting, embossing, pasting, knurling or spraying or other processes.
[0036] In order to obtain better technical effects, in this embodiment, the inner electrode 1 and the medium tube 3 are supported by a spiral support device 5, which ensures smooth airflow and makes the annular gap substantially uniform. They can also be supported by an outer gear ring or other support devices.
[0037] By providing a raised texture 11 on the surface of the inner electrode, the ozone discharge unit can generate surface discharge at the raised texture 11 on the surface of the inner electrode, thereby increasing the concentration of ozone in the mixed gas output by the ozone discharge unit, thereby increasing the ozone yield of the ozone generator, reducing the operating power consumption of the equipment, reducing the power consumption level per kilogram of ozone produced, and reducing the operating cost.

Since the present invention only innovates the ozone discharge unit and does not change the specific structure of the ozone generator, the specific structure of the ozone generator will not be repeated.
[0039] The ozone discharge unit using the technical solution of the present invention can be applied to various ozone generators, which can significantly improve the ozone production rate of a single discharge unit and an ozone generator using the discharge unit, reduce the size of the equipment, and reduce the investment cost and operating power consumption cost.
