DETAILED DESCRIPTION

[0032] The specific implementation of the utility model will be further described in detail below in conjunction with the accompanying drawings.

[0033] Reference Figures 1 to 4 In some embodiments of the present invention, a plate-type ozone generating device includes a high-voltage electrode plate 100 and a grounding electrode plate 200 .

[0034] There is one high voltage electrode plate 100 , and dielectric layers (not shown) are respectively disposed on two opposite sides thereof.

[0035] One grounding electrode plate 200 is provided on each of the two opposite sides of the high-voltage electrode plate 100, and the dielectric layer is located between the grounding electrode plate 200 and the high-voltage electrode plate 100. A discharge gas chamber 300 is formed between each grounding electrode plate 200 and the high-voltage electrode plate 100, and an air inlet pipe 210 and an air outlet pipe 220 are formed in the grounding electrode plate 200. The air inlet 211 of the air inlet pipe is connected to the first external pipeline, and the oxygen source is connected through the first external pipeline; the air outlet 212 of the air inlet pipe is connected to the discharge gas chamber 300, the air inlet 221 of the air outlet pipe is connected to the discharge gas chamber 300, and the air outlet 222 of the air outlet pipe is connected to the second external pipeline, and the ozone collection device is connected through the second external pipeline; a cooling cavity is also formed in the grounding electrode plate 200, and the cooling cavity is connected to a cooling medium inlet 240 and a cooling medium outlet 250.

[0036] The grounding electrode plate 200 and the high-voltage electrode plate 100 can be made of corrosion-resistant metal materials, and the dielectric layer can be a dielectric material coating coated on the opposite sides of the high-voltage electrode plate 100 using existing mature processes, such as a ceramic material coating with uniform thickness and excellent performance, or a sheet-like dielectric plate attached to the opposite sides of the high-voltage electrode plate 100. A discharge gas chamber 300 for generating ozone is formed between the dielectric layer and the grounding electrode plate 200. In order to improve the discharge efficiency, the thickness of the discharge gas chamber 300 is preferably 0.1-0.2 mm.

[0037] Oxygen enters from the air inlet 211 of the air inlet pipe, and enters the discharge chamber 300 through the air inlet pipe outlet 212. The high-voltage electrode plate 100 performs high-voltage discharge, and oxygen is converted into ozone, which enters the air outlet pipe 220 through the air outlet pipe inlet 221, and is discharged into the ozone collection device through the air outlet 222 of the air outlet pipe for collection. A cooling medium, such as cooling water, enters the cooling chamber from the cooling medium inlet 240, and is discharged from the cooling medium outlet 250, cooling the grounding electrode plate 200, effectively reducing the temperature of the gas in the discharge chamber 300, and preventing ozone from decomposing again in a high-temperature environment, thereby effectively improving the output rate of ozone.

[0038] The plate-type ozone generator in the embodiment of the utility model adopts a high-voltage electrode plate 100 to discharge two grounding electrode plates 200 to form two discharge chambers 300. Compared with the prior art in which a set of plate-type ozone generators has only one discharge chamber 300, the discharge area is large and the ozone output rate is high. The plate-type ozone generator in the utility model has two discharge chambers 300, and only cooling cavities are provided on the two grounding electrode plates 200 to connect the cooling system. If the prior art wants to form two discharge chambers 300, two sets of plate-type ozone generators need to be provided, and accordingly, four sets of cooling systems are required, and the equipment is large in size and high in cost. In contrast, the plate-type ozone generator in the embodiment of the utility model has a small equipment size and low cost.

[0039] In some embodiments of the present invention, an insulating spiral guide component 400 is provided in the discharge chamber 300, the center of the spiral guide component 400 is close to the center of the discharge chamber 300, the air inlet duct outlet 212 is located at the outermost spiral end of the spiral guide component 400, and the air outlet duct inlet 221 is located at the center of the spiral guide component 400.

[0040] After the oxygen enters the discharge gas chamber 300 through the air inlet pipe 210, it first reaches the outermost spiral end of the spiral guide component 400, and flows to the air inlet 221 of the gas outlet pipe under the guidance of the spiral guide component 400, that is, the air flow flows from the outer periphery of the discharge gas chamber 300 to the middle of the discharge gas chamber 300 along the spiral direction, thereby improving the uniformity of the air flow at various locations in the discharge gas chamber 300. By providing the spiral guide component 400, the flow velocity of the gas between the high-voltage electrode plate 100 and the grounding electrode plate 200 does not change much, and the discharge energy is uniform and stable, thereby improving the ozone production efficiency.

[0041] The spiral flow guide component 400 is sandwiched between the high-voltage electrode plate 100 and the ground electrode plate 200, and is attached to both the high-voltage electrode plate 100 (specifically, the dielectric layer on the side of the high-voltage electrode plate 100) and the ground electrode plate 200. The spiral flow guide component 400 is coaxially arranged with the discharge gas chamber 300. The spiral flow guide component 400 is fixedly connected by the high-voltage electrode plate 100 and the ground electrode plate 200, and there is no need to set up a fixing structure of the spiral flow guide component 400, which is conducive to simplifying the overall structure.

[0042] For the high voltage electrode plate 100, Figure 1 and Figure 4 As shown, it includes a high-voltage electrode plate body 110 and an insulating sealing ring 120 sleeved on the periphery of the high-voltage electrode plate body 110, the circumferential outer wall of the high-voltage electrode plate body 110 is fitted with the circumferential inner wall of the insulating sealing ring 120, and the high-voltage electrode 130 of the high-voltage electrode plate body 110 is led out through the circumferential outer wall of the insulating sealing ring 120 to connect to a high-voltage power supply; the opposite side surfaces of the insulating sealing ring 120 are respectively sealed with two grounding electrode plates 200, the insulating sealing ring 120 and the grounding electrode plates 200 are fastened together, and the spiral guide component 400 is also located in the inner ring space of the insulating sealing ring 120.

[0043] On the one hand, the insulating sealing ring 120 plays the role of insulating and isolating the two grounding electrode plates 200, so that the high-voltage electrode plate 100 and the two grounding electrode plates 200 respectively maintain a relatively high voltage difference, ensuring smooth high-voltage discharge in the discharge gas chamber 300, and smoothly ionizing oxygen to generate ozone. On the other hand, the two opposite sides of the insulating electrode plate are respectively sealed and fitted with the two grounding electrode plates 200, and the insulating sealing ring 120 and the grounding electrode plates 200 are tightly connected as a whole, which can also ensure the sealing of the discharge gas chamber 300 and prevent gas leakage.

[0044] To facilitate the formation of cooling cavity, refer to Figures 5 to 9 , while combining Figures 1 to 4 The grounding electrode plate 200 includes a grounding electrode plate body 260 and a cooling cavity cover 270. A discharge gas chamber 300 is formed between the grounding electrode plate body 260 and the high-voltage electrode plate 100. The air inlet pipe 210 and the air outlet pipe 220 are both formed in the grounding electrode plate body 260. A cooling cavity groove 230 is formed on the grounding electrode plate body 260. The cooling cavity cover 270 is located on the side of the grounding electrode plate body 260 away from the high-voltage electrode plate 100. The cooling cavity cover 270 is sealed and connected with the grounding electrode plate body 260 to enclose a cooling cavity. That is, the grounding electrode plate 200 is a two-part matching structure to facilitate the forming of the cooling cavity. Specifically, the grounding electrode plate body 260 and the cooling cavity cover 270 can be fastened and connected as a whole by a plurality of screws arranged circumferentially, and a sealing ring can be provided on the matching surface to ensure the sealing of the cooling cavity.

[0045] Furthermore, the air inlet 211 of the air inlet pipe is arranged on the circumferential side surface of the grounding electrode plate body 260, so as to facilitate the external connection of the first external pipeline, and then facilitate the external connection of the oxygen source. The air outlet 212 of the air inlet pipe is arranged on one end surface a of the grounding electrode plate body 260, so as to communicate with the discharge gas chamber 300. Correspondingly, the cooling cavity groove 230 is arranged on the end surface b of the grounding electrode plate body 260, and the end surface a is opposite to the end surface b; the air inlet 221 of the air outlet pipe is also arranged on the end surface a of the grounding electrode plate body 260, so as to communicate with the discharge gas chamber 300, and the air outlet 221 of the air outlet pipe is arranged on the end surface a of the grounding electrode plate body 260, so as to communicate with the discharge gas chamber 300. The port 222 is arranged on the circumferential side of the grounding electrode plate body 260 to facilitate external connection to a second external pipeline, thereby facilitating external connection to an ozone collection device; the cooling medium inlet 240 is arranged on the circumferential side of the grounding electrode plate body 260, and the cooling medium outlet 250 is arranged on the circumferential side of the grounding electrode plate body 260 to facilitate external connection to a cooling medium circulation loop, and the cooling medium inlet 240 and the cooling medium outlet 250 are opposite to each other so that the distance between the cooling medium inlet 240 and the cooling medium outlet 250 is as far as possible, thereby increasing the cooling medium flow and improving the cooling effect.

[0046] In order to facilitate stacking, the cooling chamber cover 270, the grounding electrode plate body 260, the insulating sealing ring 120, and the high-voltage electrode plate body 110 of this embodiment are disc-shaped, and the grounding electrode plates 200 on both sides are symmetrically arranged. The discharge gas chambers 300 on both sides have the same structure and size.

[0047] To facilitate external connection of related pipelines, such as Figures 5 to 8 As shown, a plane portion 280 is formed at the locations of the air inlet 211 of the air intake pipe, the air outlet 222 of the air outlet pipe, the cooling medium inlet 240, and the cooling medium outlet 250, that is, the circumferential side of the grounding electrode plate body 260 at the locations of the air inlet 211 of the air intake pipe, the air outlet 222 of the air outlet pipe, the cooling medium inlet 240, and the cooling medium outlet 250 are cut into a plane.

[0048] As an embodiment, the air inlet 211 of the air inlet pipe and the cooling medium inlet 240 are located on the same plane portion 280 of the grounding electrode plate body 260 , and the air outlet 222 of the air outlet pipe and the cooling medium outlet 250 are both located on another plane portion 280 of the grounding electrode plate body 260 .

[0049] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
