Description

Technical Field

[0001] This invention relates to the field of ozone preparation technology, specifically to a high-efficiency ozone generator. Background Technology

[0002] An ozone generator is a device that converts oxygen or air into ozone through high-voltage discharge. It is widely used in water treatment, disinfection, and industrial oxidation. Its core working unit is typically a tubular discharge structure. Under the action of a high-voltage electrode and a dielectric barrier layer, the gas is broken down and ionized to generate ozone. Because the discharge process generates a large amount of heat, and ozone has poor thermal stability, its decomposition is accelerated by increased temperature. Therefore, effective cooling of the discharge tube is essential to maintain a high ozone yield and stable equipment operation.

[0003] In existing technologies, a common cooling method involves installing a water-cooled jacket outside the ozone generating tube, using circulating cooling water to remove the heat generated by the discharge. During operation, the cooling water flows in the annular gap between the tube and the ozone generating tube, undergoing forced convection heat exchange with the tube wall made of materials such as ceramic. This structure can significantly reduce the tube temperature and ensure ozone production efficiency.

[0004] However, the existing water cooling methods still have the following drawbacks: In practical industrial applications, cooling systems typically use non-pure water, which inevitably contains calcium and magnesium ions and other impurities. Under the influence of the discharge thermal field and electric field, these impurities easily deposit and scale on the outer wall of the ceramic tube, forming a scale layer. The thermal conductivity of scale is much lower than that of the ceramic tube wall material. Once formed, it drastically increases the heat transfer resistance, leading to a continuous decrease in heat exchange efficiency, an increase in tube temperature, and thus accelerating the thermal decomposition of ozone, seriously affecting the ozone production efficiency and yield stability. Traditional solutions require periodic shutdowns to disassemble the tubes for manual or chemical cleaning, which is not only costly to maintain but also causes production interruptions, failing to meet the requirements for continuous operation. Summary of the Invention

[0005] The purpose of this invention is to provide a high-efficiency ozone generator to solve the problems in the prior art where scale on the outer wall of the ozone generating tube is difficult to remove online, resulting in reduced heat exchange efficiency, decreased ozone yield, high downtime cleaning and maintenance costs, and impact on continuous production.

[0006] The technical problem to be solved by the present invention can be achieved through the following technical solution: A high-efficiency ozone generating device includes a shell and a plurality of ozone generating tubes arranged in a ring inside the shell.

An annular plate supporting the lower fixed part is installed inside the shell, and a driving mechanism for driving the rotating part to rotate and the squeezing part to rise and fall is installed on the annular plate. When the squeezing part descends, it squeezes the elastic transverse sliding part, thereby driving the cleaning part to move laterally to contact the outer wall of the ozone generating tube.

The spring is installed between the end of the cylinder and the stop block.

[0009] Preferably, the extrusion member includes a frustum portion, an annular portion, and a guide cover. The frustum portion is connected to the bottom end of the annular portion, and the inner diameter of the frustum portion gradually increases from the direction away from the annular portion. The guide cover is disposed at the top end of the annular portion, and the guide cover is slidably sleeved with the rotating portion.

[0010] Preferably, the driving mechanism includes a servo motor, a gear disk, gears, a lead screw, and a cross connector. The gears are fitted onto the bottom outer wall of the rotating part. The gear disk meshes with multiple gears. The servo motor is mounted on the top of the annular plate and is used to drive the gear disk to rotate. The lead screw is coaxially connected to the top of the gear disk. The ends of the cross connectors are respectively connected to the outer walls of each annular part, and the cross connectors are threadedly sleeved with the lead screw.

[0011] Preferably, the extrusion member further includes an elastic sleeve, which is connected to the inner sidewalls of the frustum portion and the annular portion respectively.

[0012] Preferably, the pipe fitting further includes a tapered portion connected to the bottom end of the lower fixed portion, the inner diameter of the tapered portion gradually decreasing from top to bottom, and the tapered portion being open at the bottom end. The bottom end of the ozone generating pipe is connected to a sealing element for sealing the tapered portion, and the top end of the ozone generating pipe is connected to an annular cover plate. The top of the housing is equipped with a cylinder for controlling the lifting and lowering of the annular cover plate.

[0013] Preferably, the bottom of the annular cover is connected to an annular plug for sealing the upper fixing part, and the annular plug is sleeved with the outer wall of the top end of the ozone generating tube, and a drain outlet is connected to the side wall of the housing near the bottom end.

[0014] Preferably, the sealing element includes an upper guide portion and a lower sealing portion. The lower sealing portion abuts against the inner wall of the conical portion. The outer diameter of the bottom end of the upper guide portion is equal to the outer diameter of the top end of the lower sealing portion. The outer diameter of the top end of the upper guide portion is equal to the outer diameter of the ozone generating tube. The outer diameter of the upper guide portion gradually decreases from the direction away from the lower sealing portion.

[0015] Preferably, the sealing element is a hollow structure with an open bottom end, the bottom end of the ozone generating tube is connected to a lower corrugated pipe that passes through the sealing element, the bottom of the housing is equipped with an air inlet ring that communicates with the lower corrugated pipe, and the air inlet ring is connected to an air inlet main pipe, the top end of the ozone generating tube is connected to an upper corrugated pipe, the upper corrugated pipe is connected to an air outlet ring installed at the top of the inner end of the housing, and the air outlet ring is connected to an air outlet main pipe that extends to the outside of the housing.

[0016] Compared with the prior art, the beneficial effects of this application are as follows: 1. The pipe fitting of the present invention consists of an upper fixed part, a rotating part, and a lower fixed part, forming a water-cooling cavity inside, and a cleaning component is installed at the rotating part. The cleaning component is connected to the rotating part through an elastic transverse component. During normal operation, the elastic transverse component keeps the cleaning component in a retracted state, separated from the outer wall of the ozone generating pipe, and does not obstruct the heat exchange surface, ensuring that the cooling water in this area has sufficient contact with the pipe wall for heat exchange. When it is necessary to remove scale, the drive mechanism drives the extrusion component to descend, squeezing the elastic transverse component to make it move radially, pressing the cleaning component tightly against the outer wall of the ozone generating pipe; at the same time, the drive mechanism drives the rotating part to rotate, and the cleaning component rotates around the pipe to scrape and remove scale from the pipe wall online. After cleaning is completed, the drive mechanism controls the extrusion component to rise and reset, and the elastic transverse component drives the cleaning component to move laterally and reset, so that it is once again separated from the outer wall of the ozone generating pipe, avoiding the heat exchange effect of this part due to adhesion and coverage. Therefore, it can automatically keep the pipe wall clean, maintain efficient heat exchange, ensure long-term stability of ozone production efficiency, and significantly reduce maintenance frequency and labor costs without disassembling the equipment or interrupting operation.

[0017] 2. In this invention, the cleaning component is not always in contact with the outer wall of the ozone generating pipe. Instead, it is only driven by the squeezing component to move radially and contact the pipe wall when cleaning is required. After scraping, it automatically separates and resets. This design solves the problems of heat exchange efficiency reduction and ozone yield decrease caused by scale deposition, avoids excessive wear caused by long-term contact operation of the cleaning component, and eliminates the obstruction of the heat exchange area of ​​the pipe wall by the cleaning component during non-cleaning periods, ensuring sufficient contact heat exchange between the cooling water and the pipe wall.

Detailed Implementation

[0020] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] Example 1 In existing technologies, when ozone generating tubes are cooled by external circulating water, impurities such as calcium and magnesium ions in the industrial cooling water are easily deposited and scaled on the outer wall of the ceramic tube under the action of the discharge thermal field and electric field. Once the scale layer forms, it will drastically increase the thermal resistance, leading to a continuous decrease in heat exchange efficiency, an increase in tube temperature, and thus accelerating the thermal decomposition of ozone. This seriously affects the ozone production efficiency and output stability, and requires shutdown for cleaning.

[0022] like Figures 1 to 3In this embodiment, a high-efficiency ozone generator is provided, including a housing 100 and a plurality of ozone generating tubes 200 arranged in a ring within the housing 100. The ozone generating tubes 200 are characterized by having a fitting 300 on their outer side, and the area between the fitting 300 and the ozone generating tubes 200 is used to inject flowing water for heat dissipation. The fitting 300 includes an upper fixed part 301, a rotating part 302, and a lower fixed part 303 connected sequentially from top to bottom. A cleaning component 400 is provided inside the fitting 300. An elastic transverse member 500 is installed between the 00 and the rotating part 302. An extrusion member 600 is slidably sleeved on the rotating part 302 above the elastic transverse member 500. An annular plate 107 supporting the lower fixing part 303 is installed inside the housing 100. A drive mechanism 700 for driving the rotating part 302 to rotate and the extrusion member 600 to rise and fall is installed on the annular plate 107. When the extrusion member 600 descends, it extrudes the elastic transverse member 500, thereby causing the cleaning member 400 to move laterally to contact the outer wall of the ozone generating tube 200.

[0023] The working principle of this embodiment is as follows: Figure 2 During normal ozone generation, cooling water flows between the pipe 300 and the ozone generating pipe 200 to dissipate heat. At this time, the extruder 600 is in a high position, the elastic transverse member 500 is not subjected to radial pressure, and the cleaning member 400 retracts under the action of elastic force, maintaining a gap with the outer wall of the ozone generating pipe 200 to avoid obstructing water flow and blocking the heat exchange surface. When scale removal is required, the drive mechanism 700 drives the rotating part 302 to rotate, while simultaneously causing the extruder 600 to descend. During the descent of the extruder 600, its inner working surface gradually presses against the outer end of the elastic transverse member 500, forcing the elastic transverse member 500 to produce radial inward displacement, thereby causing the cleaning member 400 to adhere tightly to the outer wall of the ozone generating pipe 200. As the rotating part 302 continues to rotate, the cleaning member 400 performs a circumferential scraping motion around the outer wall of the ozone generating pipe 200, removing the attached scale layer in real time. After cleaning, the extrusion component 600 rises and resets, and the elastic transverse component 500 drives the cleaning component 400 out of the tight state, restoring separation from the pipe wall and ensuring that heat exchange in this area is not affected.

[0024] It should be emphasized that the core improvement of this embodiment lies in the fact that the cleaning component 400 is not always in contact with the outer wall of the ozone generating tube 200. Instead, it is only driven by the extrusion component 600 to move the elastic transverse component 500 radially and make it contact the tube wall when descaling is required. After scraping, it automatically separates and resets. This design solves the problems of heat exchange efficiency reduction and ozone yield decrease caused by scale deposition, avoids excessive wear caused by long-term contact operation of the cleaning component 400, and eliminates the obstruction effect of the cleaning component 400 on the heat exchange area of ​​the tube wall during non-descaling periods, ensuring sufficient contact heat exchange between the cooling water and the tube wall.

[0025] like Figures 1 to 2In this embodiment, to facilitate the entry and exit of circulating water, an upper water ring 101 and a lower water ring 102 are respectively fitted onto the outer side wall of the housing 100 from top to bottom. The upper water ring 101 and the lower water ring 102 are respectively connected to a main outlet pipe 103 and a main inlet pipe 104. A water outlet conduit 105 penetrating the side wall of the housing 100 is connected between the upper water ring 101 and the upper fixed part 301, and a water inlet conduit 106 penetrating the side wall of the housing 100 is connected between the lower water ring 102 and the lower fixed part 303. This allows cooling water to enter from the bottom and exit from the top, flowing evenly through each pipe 300, ensuring uniform heat dissipation.

[0026] like Figures 4 to 6 In this embodiment, the elastic transverse component 500 includes a cylinder 501, a piston 502, a protruding rod 503, a spring 504, and a stop block 505. Two cylinders 501 are symmetrically connected and disposed on the side wall of the rotating part 302. One end of the protruding rod 503 is connected to the side wall of the cleaning component 400, and the other end of the protruding rod 503 slides through the end of the cylinder 501 and extends outward. The piston 502 is slidably disposed with the cylinder 501 and is fitted onto the protruding rod 503. The stop block 505 is fitted onto the protruding rod 503 near its end. The spring 504 is installed between the end of the cylinder 501 and the stop block 505. This structure utilizes the preload of the spring 504 to maintain the retracted tendency of the cleaning component 400, while the piston 502 prevents cooling water from leaking along the cylinder 501, ensuring a seal. To facilitate the sliding of the protruding rod 503 under pressure, its end is designed as a spherical structure. When the extruder 600 descends, its inner conical surface presses against the spherical structure at the end of the protruding rod 503, forcing the protruding rod 503 to slide radially inward. This, in turn, causes the cleaning component 400 to press against the outer wall of the ozone generating tube 200, thus achieving radial feeding of the cleaning component 400. like Figure 5 and Figure 7In this embodiment, the extruder 600 includes a frustum 601, an annular portion 602, and a guide cover 603. The frustum 601 is connected to the bottom end of the annular portion 602, and the inner diameter of the frustum 601 gradually increases from the direction away from the annular portion 602, forming a conical surface. The guide cover 603 is disposed at the top end of the annular portion 602, and the guide cover 603 is slidably sleeved with the rotating portion 302 to ensure that the extruder 600 rises and falls smoothly. When the extruder 600 descends, the conical surface of the frustum 601 gradually contacts the spherical structure at the end of the protrusion 503 and presses it to slide radially inward. As the end of the protrusion 503 enters the inner wall region of the annular portion 602, since the inner diameter of the annular portion 602 remains unchanged, the radial position of the protrusion 503 is locked. At this time, the cleaning component 400 just keeps in contact with the outer wall of the ozone generating tube 200. Within the height range of the annular portion 602, as long as the end of the protruding rod 503 is located therein, the cleaning component 400 can maintain contact with the outer wall of the ozone generating tube 200. Furthermore, in this embodiment, the maximum descent stroke of the extrusion component 600 is designed to prevent the guide cover 603 from colliding with the elastic transverse component 500 below at its extreme position, ensuring the structural safety. This design, utilizing conical surface guidance and equal-diameter section locking, achieves stable holding of the cleaning component 400 after it has been fed into position, resulting in a simple structure and reliable operation.

[0027] like Figure 3 and Figure 8 In this embodiment, the drive mechanism 700 includes a servo motor 701, a gear 702, a gear 703, a lead screw 704, and a cross connector 705. The gear 703 is fitted onto the outer wall of the bottom end of the rotating part 302. The gear 702 is meshed with multiple gears 703. The servo motor 701 is mounted on the top of the annular plate 107 and is used to drive the gear 702 to rotate. The lead screw 704 is coaxially connected to the top of the gear 702. The ends of the cross connector 705 are respectively connected to the outer walls of each annular part 602, and the cross connector 705 is threadedly sleeved with the lead screw 704. During operation, the servo motor 701 drives the gear 702 to rotate. On the one hand, the gear 703 drives each rotating part 302 to rotate synchronously. On the other hand, the lead screw 704 drives the cross connector 705 and all the extrusion parts 600 to rise and fall synchronously. A single power source can realize the linkage of rotation and lifting, resulting in a compact structure and high synchronization.

[0028] It should be noted that in this embodiment, the servo motor 701 adopts an intermittent working mode. Its working process involves first rotating clockwise to lower the extrusion component 600, and then rotating counterclockwise to reset it, raising the extrusion component 600 back to its original position, thus completing one complete lifting and lowering action. The number of lifting and lowering operations is not specifically limited and can be set according to actual cleaning needs. After each working cycle, the servo motor 701 ensures that the extrusion component 600 returns to its initial height, restoring the separation between the cleaning component 400 and the outer wall of the ozone generating tube 200, thus avoiding any impact on heat exchange of the tube wall during non-cleaning periods.

[0029] like Figure 7 In this embodiment, the extrusion member 600 further includes an elastic sleeve 604, which is connected to the inner sidewalls of the frustum portion 601 and the annular portion 602, respectively. When the cleaning member 400 wears down during long-term use, the elastic sleeve 604 can provide radial compensation through its own elastic deformation when the extrusion member 600 descends into place, allowing the protrusion 503 to be pressed inward a certain distance, thereby compensating for the wear of the cleaning member 400 and ensuring that the cleaning member 400 can still maintain a reliable contact with the outer wall of the ozone generating tube 200, thus ensuring the long-term stability of the descaling effect.

[0030] Example 2 It is understandable that in Example 1, the use of circulating water heat exchange results in cooling water remaining in the pipe 300 when ozone generation stops. This water also contains scale debris that has been removed during cleaning. If it is not removed in time, the scale debris can easily re-adhere to the outer wall of the ozone generating pipe 200, weakening the cleaning effect and even aggravating local scaling.

[0031] like Figure 2 and Figure 5 To solve the above problems, the pipe fitting 300 also includes a tapered portion 304 connected to the bottom end of the lower fixed portion 303. The inner diameter of the tapered portion 304 gradually decreases from top to bottom, and the tapered portion 304 is open at the bottom. The bottom end of the ozone generating pipe 200 is connected to a sealing element 800 for sealing the tapered portion 304, and the top end of the ozone generating pipe 200 is connected to an annular cover plate 900. The top of the housing 100 is equipped with a cylinder 902 for controlling the lifting and lowering of the annular cover plate 900.

[0032] The working principle of this embodiment is as follows: Figure 2During normal operation, cylinder 902 is extended, and the annular cover plate 900 is pressed down, causing the seal 800 at the bottom of the ozone generating tube 200 to be tightly seated inside the conical portion 304, achieving bottom sealing. Cooling water can only flow within the annular cavity between the pipe 300 and the ozone generating tube 200. When production stops and drainage is required, cylinder 902 retracts, and the annular cover plate 900 lifts the ozone generating tube 200 and the seal 800 together a certain distance. The seal 800 disengages from the conical portion 304, opening the bottom channel. Cooling water containing scale debris flows out through the bottom of the conical portion 304 under gravity, preventing scale debris from re-adhering to the tube wall of the ozone generating tube 200.

[0033] It should be emphasized that the core improvement of this embodiment is that a tapered part 304 is provided at the lower end of the pipe fitting 300 and cooperates with the sealing part 800. This is linked with the controllable lifting and lowering annular cover plate 900 and cylinder 902 to form an openable and closable bottom sewage discharge channel. When the machine is stopped, the bottom can be opened by lifting the ozone generating pipe 200 to quickly drain the scale-containing cooling water, which fundamentally prevents the secondary adhesion of scale debris on the pipe wall and solves the problem of repeated cleaning effects caused by residual sewage.

[0034] like Figures 2 to 3 In this embodiment, the bottom of the annular cover plate 900 is connected to an annular plug 901 for sealing the upper fixing part 301, and the annular plug 901 is sleeved with the outer wall of the top end of the ozone generating tube 200. When the cylinder 902 is pressed down, the annular plug 901 is inserted into the upper end of the upper fixing part 301 to prevent cooling water from overflowing upwards and to ensure the top is sealed. A drain port 108 is connected to the side wall of the housing 100 near the bottom end for discharging sewage.

[0035] like Figure 5 and Figure 9 In this embodiment, the sealing element 800 includes an upper guiding part 801 and a lower sealing part 802. The lower sealing part 802 abuts against the inner wall of the conical part 304. The outer diameter of the bottom end of the upper guiding part 801 is equal to the outer diameter of the top end of the lower sealing part 802. The outer diameter of the top end of the upper guiding part 801 is equal to the outer diameter of the ozone generating tube 200. The outer diameter of the upper guiding part 801 gradually decreases from the direction away from the lower sealing part 802. This ensures a smooth transition between the sealing element 800 and the outer wall of the ozone generating tube 200, reducing water flow resistance. It also allows the scale to slide down with the help of the conical surface during sewage discharge, preventing accumulation.

[0036] Example 3 It is understandable that in Embodiment 2, the ozone generating tube 200 will move up and down under the drive of the cylinder 902. If the two ends of the tube are rigidly connected to the air circuit, repeated up and down movement can easily lead to loosening of the interface, air leakage, or even fatigue damage of the pipeline.

[0037] like Figure 9To solve the above problems, the seal 800 is a hollow structure with an open bottom. The bottom end of the ozone generating tube 200 is connected to a lower corrugated pipe 201 that passes through the seal 800. An air intake ring 202 that communicates with the lower corrugated pipe 201 is installed at the bottom of the housing 100, and an air intake manifold 203 is connected to the air intake ring 202. An upper corrugated pipe 204 is connected to the top of the ozone generating tube 200. An air outlet ring 205 installed at the top of the inner part of the housing 100 is connected to the upper corrugated pipe 204, and an air outlet manifold 206 extending to the outside of the housing 100 is connected to the air outlet ring 205.

[0038] The working principle of this embodiment is as follows: Figure 9 The raw material gas enters the intake ring 202 through the intake manifold 203, and then is sent to the bottom of the ozone generating pipe 200 through the lower corrugated pipe 201. The ozone generated by the discharge enters the outlet ring 205 from the upper end through the upper corrugated pipe 204, and is supplied to the outside through the outlet manifold 206. When the cylinder 902 drives the ozone generating pipe 200 to rise and fall, the lower corrugated pipe 201 and the upper corrugated pipe 204 can freely extend and retract, completely compensating for the displacement. The gas circuit connection always remains sealed and reliable. At the same time, the corrugated pipe can also absorb the length change caused by thermal expansion and contraction, avoiding pipeline stress.

[0039] It should be emphasized that the core improvement of this embodiment is that a lower corrugated pipe 201 and an upper corrugated pipe 204 are respectively installed at the inlet and outlet ends of the ozone generating pipe 200, forming a flexible air path connection with the fixed inlet ring 202 and outlet ring 205. This solves the problem of displacement damage to the rigid connection caused by lifting sewage discharge and thermal expansion and contraction, enabling the equipment to ensure the long-term reliability of the air path sealing while having both online descaling and sewage discharge functions.

[0040] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed application.
