Description

Technical Field

[0001] This utility model relates to the field of ozone generators, and in particular to a support structure for a plate-type ozone generator. Background Technology

[0002] An ozone generator is a device used to produce ozone gas. Because ozone is easily decomposed and cannot be stored, it needs to be produced and used on-site. This makes ozone generators widely used in various production, processing or living environments that require ozone.

[0003] In a commonly used plate-type ozone generator, the cathode of the discharge chamber is an aluminum plate with a ceramicized outer shell. A ceramic sheet acts as a barrier discharge body, and a silver layer sintered on the back of the ceramic sheet serves as the high-voltage anode. The discharge gas flow channel between the ceramic sheet and the cathode is formed by support. The ceramic sheet lies on the support and is pressed tightly. The gas flow passes through the support gaps, and the high voltage generates a corona discharge that decomposes oxygen. Some of the oxygen atoms then form ozone molecules.

[0004] The alternating current generated by high-frequency high-voltage electricity flows repeatedly through the silver layer, and the resulting electromagnetic force continuously vibrates the ceramic sheet. Local stress concentration will occur at the support edge. Long-term vibration will cause material fatigue and fracture. The fracture of the ceramic sheet will cause a short circuit between the silver layer and the cathode, leading to failure. Therefore, in order to reduce the stress concentration caused by vibration, elastic materials are needed to support the ceramic sheet to ensure the stability and reliability of the ozone generation process. Utility Model Content

[0005] The purpose of this invention is to provide a support structure for a plate-type ozone generator, which has the advantage of helping to improve the stability and reliability of the ozone generator during operation.

[0007] Furthermore, the polytetrafluoroethylene support spring is also provided with a glass fiber layer.

[0008] Furthermore, both the inlet transverse groove and the outlet transverse groove are connected to the ionization chamber.

[0009] Furthermore, the ionization tank is provided with a support platform edge that is aligned with the edge of the polytetrafluoroethylene support spring.

[0010] Furthermore, a limiting ring edge is also provided on the outer aluminum plate surrounding the ionization tank.

[0011] Furthermore, the groove depth of the strip is less than the thickness of the strip, and the thickness of the strip is less than 0.1 mm.

Detailed Implementation

[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] Example: A support structure for a plate-type ozone generator, such as... Figure 1 and Figure 2 As shown, it includes an outer aluminum plate 1 and a ceramic sheet 2. The surface of the outer aluminum plate 1 is covered with a ceramic layer. The outer aluminum plate 1 is provided with an ionization tank 3 for the ceramic sheet 2 to be fitted. The outer aluminum plate 1 is also provided with a limiting ring edge 16 around the ionization tank 3. When the ceramic sheet 2 is engaged with the outer aluminum plate 1, the limiting ring edge 16 is kept in contact with the ceramic plate, and a reliable ozone reaction space is formed between it and the ionization tank 3.

[0019] The outer aluminum plate 1 is also provided with an air inlet slot 4, an air outlet slot 5, a water inlet hole 6, and a drain hole 7. Gas is input through the air inlet slot 4. The outer aluminum plate 1 serves as the cathode of the discharge chamber of the plate ozone generator, and the ceramic sheet 2 serves as the blocking discharge body. A high-voltage anode silver layer is provided on the side of the ceramic sheet 2 near the ionization tank 3, which satisfies the requirement that the silver layer sintered on the back of the ceramic sheet 2 serves as the high-voltage anode. A polytetrafluoroethylene support spring 8 is provided between the outer aluminum plate 1 and the ceramic sheet 2. The ionization tank 3 is provided with a support platform edge 15 aligned with the edge of the polytetrafluoroethylene support spring 8. The discharge gas flow channel between the high-voltage anode and the cathode is formed by the support spring 8. The ceramic sheet 2 is pressed on the support spring 8, and the gas flow passes through the support gap. After the high voltage generates a corona, it decomposes the oxygen, and some oxygen atoms form ozone molecules, completing the ozone generation process.

[0020] The alternating current generated by high-frequency high-voltage electricity flows repeatedly through the high-voltage anode silver layer, and the resulting electromagnetic force continuously vibrates the ceramic sheet 2. The polytetrafluoroethylene support spring 8 can effectively reduce the stress concentration caused by the vibration, so as to ensure the stability and reliability of the ozone generation process.

[0021] The ionization tank 3 has an inlet transverse groove 9 and an outlet transverse groove 10 at its two ends, respectively. Both the inlet transverse groove 9 and the outlet transverse groove 10 are connected to the ionization chamber 13. The inlet transverse groove 9 is connected to the inlet groove 4, and the outlet groove 5 is connected to the outlet transverse groove 10. This ensures that the input gas can fully enter the ionization tank 3 through the inlet transverse groove 9, and that the ozone gas generated after the reaction enters the outlet groove 5 in an orderly manner from the outlet transverse groove 10 for discharge. During this process, water is continuously injected between the water inlet hole 6 and the drain hole 7 for water cooling to ensure a reliable working environment temperature during the high-voltage discharge process.

[0022] The bottom of the ionization tank 3, located between the inlet transverse groove 9 and the outlet transverse groove 10, is uniformly provided with multiple strip-shaped grooves 11. The polytetrafluoroethylene support spring 8 is provided with strips 12 that fit into the strip-shaped grooves 11, so that the support spring 8 can provide reliable support when the ceramic sheet 2 is fitted into the ionization tank 3. The groove depth of the strip-shaped groove 11 is less than the thickness of the strip 12, and the thickness of the strip 12 is less than 0.1 mm, which ensures that the ceramic sheet 2 is as close as possible to the bottom of the ionization tank 3 while ensuring a reliable ionization gap.

[0023] Adjacent strips 12 divide the polytetrafluoroethylene support spring 8 into multiple ionization chambers 13. At this time, the strips 12 are engaged in the strip groove 11. The gas entering through the inlet transverse groove 9 reacts in the multiple ionization chambers 13 and is then discharged from the ionization chamber 3 through the outlet transverse groove 10. All ozone reactions occur within the gaps supported by the support spring 8.

[0024] Because the polytetrafluoroethylene support spring 8 will undergo local breakdown and surface modification under the combined action of high voltage electric field and high concentration of ozone, its mechanical strength will decrease and electrochemical corrosion will be triggered. The polytetrafluoroethylene support spring 8 is also provided with a glass fiber layer 14. The addition of the glass fiber layer 14 under high temperature environment can significantly improve the mechanical properties and electrical resistance of the polytetrafluoroethylene film, improve the working reliability of the support spring 8, and ensure a stable ozone reaction preparation process.

[0025] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
