Description

Technical Field

[0001] The present invention relates to the technical field of ozone preparation, and particularly to a plate-type ozone generating device. Background Art

[0002] The preparation methods of ozone can be roughly divided into: electrolysis method, corona discharge method, and ultraviolet photochemical method. Among them, the plate-type ozone generator uses a ceramic plate as a dielectric layer to conduct high-voltage discharge, thereby decomposing oxygen, making the oxygen decompose into oxygen molecules, and then the oxygen molecules combine to form ozone.

[0003] The existing patent CN222781403U, a plate-type ozone generating device, includes a high-voltage electrode plate and a grounded electrode plate. Dielectric layers are respectively provided on the opposite two side surfaces of the high-voltage electrode plate; a grounded electrode plate is arranged on each of the opposite two sides of the high-voltage electrode plate, and a discharge chamber is formed between each grounded electrode plate and the high-voltage electrode plate. An air inlet pipe and an air outlet pipe are formed in the grounded electrode plate. The air inlet of the air inlet pipe is communicated with a first external pipeline, the air outlet is communicated with the discharge chamber, the air inlet of the air outlet pipe is communicated with the discharge chamber, and the air outlet is communicated with a second external pipeline; a cooling cavity is also formed in the grounded electrode plate, and the cooling cavity is communicated with a cooling medium inlet and a cooling medium outlet. The present invention uses one high-voltage electrode plate to discharge to two grounded electrode plates, constituting two discharge chambers, with a large discharge area and a high ozone production rate; the equipment has a small volume and low cost.

[0004] However, in the actual preparation process, it is necessary to stand for a period of time in the ozone forming inner cavity to make the oxygen molecules fully combine, or use ultraviolet irradiation or high-voltage corona to stimulate the oxygen molecules, so as to improve the forming efficiency and concentration of ozone.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1 to 12 , the present invention provides a technical solution:

[0034] Embodiment 1: A plate-type ozone generating device includes a generating device housing 1. A plate-type electrode assembly for discharging and decomposing oxygen is arranged in the generating device housing 1. An air inlet end 3 is arranged on one side of the plate-type electrode assembly, and an exhaust end 8 is arranged on the other side. The exhaust end 8 is externally connected to an excitation assembly. The plate-type electrode assembly includes a group of high-voltage electrode plates 2 located at the middle position inside the generating device housing 1. Grounding electrode plates 4 are symmetrically arranged on both sides of the high-voltage electrode plate 2. The high-voltage electrode plate 2 is externally connected to a high-voltage power supply. A discharge gap 5 is left between the high-voltage electrode plate 2 and the grounding electrode plate 4. One end of the discharge gap 5 is provided with an air inlet end 3 connected to an external pure oxygen source, and the other end of the discharge gap 5 communicates with the exhaust end 8.

[0035] Through the discharge between the high-voltage electrode plate 2 and the grounding electrode plate 4, the oxygen in the discharge gap 5 is decomposed into oxygen molecules.

[0036] A heat dissipation gap is left between the grounding electrode plate 4 and the inner wall of the generating device housing 1. A heat dissipation folding plate 7 is arranged in the heat dissipation gap. One end of the bending section of the heat dissipation folding plate 7 is attached to the outer side wall of the grounding electrode plate 4, and a cooling coil 6 is installed on the other end of the bending end of the heat dissipation folding plate 7.

[0037] By arranging the cooling coil 6 and the heat dissipation folding plate 7, sufficient heat dissipation of the plate-type electrode assembly is realized, ensuring the stable and continuous operation of the equipment.

[0038] The excitation assembly includes an excitation disk 9 and an ultraviolet lamp 14. Multiple layers of connected annular gas flow channels 18 are arranged on the excitation disk 9. An air inlet 19 communicating with the exhaust end 8 is arranged outside the gas flow channel 18. An air outlet pipe 10 for discharging ozone is arranged in the middle of the gas flow channel 18. An airway side wall 24 for isolation is arranged between adjacent gas flow channels 18. An opening 21 is arranged on the airway side wall 24 between adjacent gas flow channels 18. The openings 21 on adjacent gas flow channels 18 are mutually offset to form a gas circulation path with the maximum stroke.

[0039] By arranging the gas flow channel 18 to form a long-distance gas circulation channel, it is ensured that they are fully combined under the irradiation of the ultraviolet lamp 14 to form ozone, ensuring the concentration and efficiency of ozone formation.

[0040] On the other side of the excitation disk 9, there is an ultraviolet lamp 14 that irradiates the gas flow channel 18 directly. One end of the air outlet pipe 10 is connected to the innermost gas flow channel 18. A concentration detection device 11 for detecting the ozone concentration is provided on the air outlet pipe 10.

[0041] By providing the transparent cover 15, the sealing of the gas flow channel 18 is ensured, enabling the air flow to move along the specified flow channel. Under the action of the light guide cover 13, the ultraviolet lamp 14 irradiates the gas flow channel 18 through the transparent cover 15, achieving sufficient excitation of the decomposed oxygen molecules, making the oxygen molecules more active, and improving the ozone formation efficiency.

[0042] Multiple groups of air column components 20 installed with elastic expansion are provided in the multi-layer gas flow channel 18. A folding hose 12 is provided on the air outlet pipe 10. A nozzle joint 22 that squeezes and communicates with the air column component 20 is provided at the end of the folding hose 12.

An inner air channel 31 that communicates the gas flow channel 18 with the folding hose 12 is provided inside the air column component 20.

[0043] By providing the connection between the nozzle joint 22 and the air column component 20, a section of the gas flow channel 18 can be selectively intercepted, thereby controlling the time length of the gas passing through the gas flow channel 18, and indirectly achieving the purpose of controlling the irradiation time of the ultraviolet lamp 14, realizing precise control of the excitation time.

[0044] Working principle: First, the purified and dried pure oxygen enters the discharge gap 5 through the intake end 3, and then through the discharge between the high-voltage electrode plate 2 and the grounded electrode plate 4, the oxygen passing through the discharge gap 5 is decomposed into oxygen molecules. The decomposed oxygen molecules interact to form ozone. The uncombined oxygen molecules and ozone enter the excitation disk 9 through the exhaust end 8 and flow in the gas flow channel 18 in the excitation disk 9. By providing the connection between the nozzle joint 22 and the air column component 20, a section of the gas flow channel 18 can be selectively intercepted, thereby controlling the time length of the gas passing through the gas flow channel 18, and indirectly achieving the purpose of controlling the irradiation time of the ultraviolet lamp 14, realizing precise control of the excitation time, enabling the oxygen molecules to fully combine to form ozone, and the ozone enters the air outlet pipe 10 through the air column component 20 and the folding hose 12 and is discharged.

[0045] Embodiment 2: On the basis of Embodiment 1, a receiving groove 25 and a compression groove 26 for telescopically mounting the air column assembly 20 are provided on the gas flow channel 18. The air column assembly 20 includes a lifting air column 30 installed in the receiving groove 25 and a stepped pipe 29 installed in the compression groove 26. The stepped pipe 29 is fixedly connected to the lifting air column 30 through an eccentrically arranged connecting pipe 33.

One end of the inner air channel 31 communicates with the air holes, the other end of the inner air channel 31 communicates with the port of the stepped pipe 29, and the middle section of the inner air channel 31 extends along the connecting pipe 33.

[0046] The sliding installation of the air column assembly 20 is realized by setting the receiving groove 25 and the compression groove 26, and the connection of the air channels is realized by using the inner air channel 31.

[0047] A partition is provided between the receiving groove 25 and the compression groove 26. The connecting pipe 33 slides through the partition. A spring 27 is pressed between the upper end of the stepped pipe 29 and the partition. An air channel interface 23 communicating with the compression groove 26 is provided on the outer side wall of the excitation disk 9. A retaining ring 28 is fixedly installed in the air channel interface 23. The end of the stepped pipe 29 slides through the middle through hole of the retaining ring 28.

[0048] The elastic installation of the air column assembly 20 is realized by setting the spring 27, and the position of the stepped pipe 29 is limited by using the retaining ring 28, so that under the reset elastic force of the spring 27, the lifting air column 30 is received in the receiving groove 25, realizing the sealing of the air column assembly 20 and avoiding air leakage.

[0049] The air nozzle joint 22 includes a joint assembly 32 connected to the stepped pipe 29 and a pressing ring 35 pressed on the retaining ring 28. The joint assembly 32 includes a second pressing pipe 38 inserted into the port of the stepped pipe 29 and communicating with the inner air channel 31 and a first pressing pipe 37 pressed on the end of the stepped pipe 29. The outer diameter of the first pressing pipe 37 is the same as that of the stepped pipe 29.

Cross-shaped blocks 36 that can be correspondingly inserted and rotated out of position with the cross-shaped opening grooves 34 are provided on the arc outer wall of the first pressing pipe 37. The gap between the cross-shaped blocks 36 and the pressing ring 35 is greater than the thickness of the retaining ring 28.

[0050] The connection between the folding hose 12 and the inner air channel 31 is realized through the second pressing pipe 38. By squeezing the stepped pipe 29 with the first pressing pipe 37, the spring 27 is compressed. At this time, the lifting air column 30 extends into the gas flow channel 18, realizing the connection with the gas flow channel 18. By inserting and rotating the cross-shaped blocks 36 out of position in the cross-shaped opening grooves 34, the air nozzle joint 22 is fixedly clamped on the air channel interface 23.

[0051] A sealing arc strip 16 that cooperates with and seals against the side wall 24 of the air passage is provided on the transparent cover 15. A lifting side groove 17 that fits against the outer wall of the lifting air column 30 is provided on the side wall of the gas flow passage 18. Under the extrusion of the nozzle connector 22, the end of the lifting air column 30 is tightly pressed against the transparent cover 15.

[0052] Through the cooperation of the lifting side groove 17 and the lifting air column 30, the gas flow passage 18 is cut off, so that the length of the gas passing through the gas flow passage 18 can be selectively controlled, and the purpose of controlling the irradiation time of the ultraviolet lamp 14 is achieved indirectly.

[0053] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
