Description

Technical Field

[0001] The present invention relates to the field of ozone generating devices, and in particular to an adjustable flat-plate ozone generating device and an adjustment method thereof. Background Art

[0002] With the continued acceleration of industrialization and urbanization, increasingly stringent environmental governance standards, and growing public health awareness, reliance on high-efficiency ozone generation technologies has significantly increased in a variety of applications, including air purification, water sterilization, food preservation, and medical disinfection. As a strong oxidant, ozone (O3) is widely used in industrial waste gas treatment, tap water purification, cold chain transportation disinfection, and cleanroom air control due to its efficient, rapid, and residue-free sterilization and organic matter degradation capabilities. It is a core technology in today's green environmental protection industry.

[0003] However, most current mainstream ozone generators are based on electrochemical principles such as dielectric barrier discharge (DBD) or corona discharge. They apply a high-voltage electric field between electrodes to ionize oxygen molecules, generating free oxygen, which then reacts with oxygen molecules to produce ozone. While this discharge method is technically mature, it still faces a series of technical bottlenecks and application challenges in industrial operation, severely restricting device performance and application expansion.

[0004] First, ozone generation efficiency is highly sensitive to electric field strength and distribution. Conventional ozone generators utilize a fixed electrode structure and constant voltage excitation, making it difficult to adjust electric field parameters in real time based on actual operating conditions (such as ambient temperature, gas humidity, electrode aging, and inlet gas flow rate). This results in large fluctuations in ozone production, low conversion efficiency, and high system energy consumption, making it difficult to meet the requirements of high-stability and high-efficiency industrial operation.

[0005] Secondly, existing research and experiments have shown that introducing an external magnetic field can effectively increase the migration rate and collision probability of high-energy electrons in the discharge channel, thereby enhancing the activity and rate of the ozone generation reaction. However, most current magnetic field-assisted ozone generators still use a single magnetic field direction design, with a fixed magnetic field source position and lacking the ability to dynamically adjust the field during operation. This static coupling method makes it difficult to achieve an optimal magneto-electric synergistic discharge environment and fails to fully tap the potential of magnetic field-enhanced ozone generation.

[0006] In addition, in pursuit of the magnetic field enhancement effect, some existing devices use non-disassembly structures or bulky permanent magnet components, which not only leads to a significant increase in manufacturing costs, but also creates difficulties in system integration, miniaturized deployment, modular maintenance, etc., limiting their promotion and application in multiple scenarios and platforms.

[0007] It can be seen that the existing magnetic field-assisted ozone generator has the following shortcomings: the magnetic field structure is fixed, the direction and intensity cannot be adjusted, and it cannot be optimized and controlled in real time according to the discharge state; the electrode structure is fixed, the electrode area and gap cannot be adjusted, and it is difficult to control the discharge intensity and uniformity; the magneto-electric synergy effect is limited, and it is difficult to improve the ozone generation efficiency to an ideal level.

[0008] Therefore, there is an urgent need to develop a new type of ozone generator with strong adjustability and real-time control of magnetic field direction and intensity, which can not only effectively improve the ozone generation efficiency, but also achieve energy consumption control and performance stability under actual working conditions, and provide more efficient and flexible ozone application solutions for the environmental protection industry, medical and health care, food industry, etc. Summary of the Invention

[0009] In order to overcome the above problems, the present invention provides a flat-plate ozone generator with adjustable magnetic field direction and intensity and electric field intensity, and an adjustment method thereof, so as to improve the ozone generation efficiency and regulation capability of the device, realize adaptive discharge optimization under multiple working conditions, reduce energy consumption, and improve system reliability.

[0010] The technical solution adopted by the present invention to solve the technical problem is: Adjustable flat-plate ozone generator, including The ozone generating assembly includes a housing and a ground electrode and a dielectric plate fixedly mounted therein. The dielectric plate is provided with a high-voltage electrode opposite to the dielectric plate, forming a discharge gap in an oxygen environment therebetween. The high-voltage electrode is mounted in the housing so as to be axially rotatable and axially movable via an axial adjustment mechanism. The ozone generating assembly is mirror-imaged with a radial magnetic field regulating assembly and an axial magnetic field regulating assembly on both sides; The radial magnetic field adjustment assembly includes a radial track base and a helical base. The surface of the radial track base is provided with a plurality of circumferentially equally spaced radial tracks, in which a slidable magnet is disposed. The helical base is mounted on the radial track base and has a surface provided with spiral grooves corresponding to the radial tracks. The magnet is mounted in the corresponding spiral groove via a magnet slide. The axial magnetic field adjustment assembly includes a base and an axial track. The radial track base is installed on the base. The base is driven by a ball screw mechanism to reciprocate on the axial track.

[0011] As an improvement of the above technical solution, the surface of the radial track base is provided with six circumferentially equally spaced radial tracks, and the six magnets are respectively mounted on corresponding radial tracks and can slide radially in their respective radial tracks.

[0012] As an improvement of the above technical solution, the helix base is supported and installed on the inner side of the radial track base by two helix base bearings, and cooperates with the slide seat of the magnet through a spiral groove linkage structure. When the helix base is rotated, all magnets will be driven to move synchronously along their respective radial tracks at the same time, and the radial magnetic field strength can be adjusted by adjusting the radial position of the magnet.

[0013] As an improvement to the above technical solution, a track slider is provided at the bottom of the base, and the track slider is installed on the axial track to limit the freedom of the base when moving in the axial direction and provide linear guide support.

[0014] Optionally, the radial track base is arranged on the base and fixed thereto by bolts.

[0015] As an improvement of the above technical solution, the ball screw mechanism includes a ball screw, a ball screw nut and a screw nut seat. The ball screw passes through the ball screw nut. The ball screw nut is fixedly connected to the screw nut seat. The screw nut seat is fixedly connected to the base by bolts. The outer end of the ball screw is connected to a manual operating handle through a coupling.

[0016] When the operator turns the handle, the ball screw rotates about its axis, causing the ball screw nut to move axially on the ball screw. Because the screw nut seat is fixedly connected to the base, this drives the entire base assembly to move linearly along the axial track, changing the axial distance between each magnet and the ozone generator assembly, thereby adjusting the axial magnetic field distribution intensity. The axial position change is continuous, and the position control accuracy is determined by the screw pitch and the handle rotation angle.

[0017] Optionally, the inner end of the ball screw is fixedly mounted on the bed through a screw fixed end.

[0018] Optionally, the shell is provided with an air inlet and an air outlet, which are respectively arranged at the upper and lower ends of the shell.

[0019] Optionally, the dielectric plate is fixed to the inner end of the ground electrode.

[0020] As an improvement of the above technical solution, the axial adjustment mechanism includes an electrode rotating plate mounted in cooperation with the housing, which can rotate axially without moving axially; A translation screw is installed at the axis of the electrode rotating plate, and the translation screw and the electrode rotating plate can rotate relative to the axial direction without moving relative to the axial direction; The inner end of the translation screw is threadedly connected to the electrode translation plate, and the high-voltage electrode is fixedly mounted on the electrode translation plate. The electrode translation plate and the electrode rotation plate can move axially relative to each other but will not rotate axially relative to each other. An insert ring is installed at the outer end of the translation screw, which can move axially with the translation screw without rotating axially relative to it. When the insert ring moves axially at the outer end of the translation screw to engage or disengage with the electrode rotating plate, the relative area of ​​the discharge electrodes and the width of the discharge gap are adjusted respectively.

[0021] Optionally, the translation screw is embedded in the annular pin groove through a pin and is slidably matched with the electrode rotating plate.

[0022] As an improvement to the above technical solution, when the insert ring is moved to cooperate with the electrode rotating plate, the insert ring is rotated, and the translation screw, the electrode rotating plate, the electrode translation plate, and the high-voltage electrode rotate together around the axis, thereby achieving adjustment of the relative area of ​​the discharge electrode; When the insert ring is moved to disconnect it from the electrode rotating plate, the insert ring is rotated, and the translation screw rotates axially, the electrode rotating plate and the electrode translation plate do not rotate axially, and the electrode rotating plate and the translation screw rotate relative to each other axially, and the relative axial movement of the electrode translation plate is converted into through the thread, thereby realizing the adjustment of the discharge gap width.

[0023] As an improvement of the above technical solution, support shafts are connected to both sides of the shell base of the ozone generating assembly, and the support shafts are installed in the support through support bearings arranged at both ends to realize the axial rotation function; one side of the support shaft is connected to the support handle through a support connection mechanism, and the other side of the support shaft is installed with a dial; when the support handle is rotated, the support shaft drives the shell base as a whole to rotate around the axis to adjust the angle between the discharge gap direction and the axial magnetic field direction in the ozone generating assembly.

[0024] The rotation angle is read on a scale. This structure is used to adjust the relative relationship between the magnetic field direction and the electrode arrangement direction. Angle adjustment does not change the position of the magnets, nor does it affect the original function of the radial and axial magnetic field intensity adjustment mechanisms.

[0025] The present invention introduces a structural design with adjustable magnetic field direction and intensity, combined with a dynamic adjustment mechanism for electrode spacing and area, to solve the problems of existing ozone generators, such as single adjustment means, low reaction efficiency, and unstable operation. Specifically, it brings the following beneficial effects: 1) Improve ozone generation efficiency By providing radially and axially adjustable magnetic fields, the present invention optimizes the trajectory and energy distribution of high-energy electrons in the discharge channel, effectively enhancing the activity of the ozone generation reaction. The establishment of a magneto-electric synergistic discharge environment enables the device to maintain high ozone output efficiency over a long period of time during actual operation.

[0026] 2) Enhance equipment adaptability and operational stability The present invention uses a mechanical adjustment structure for the electrode spacing and area to optimize discharge parameters in real time according to changes in operating conditions such as gas flow rate, humidity, and electrode wear, significantly reducing fluctuations in ozone production and ensuring the continuity and stability of system operation.

[0027] 3) The device has a reasonable structure and is easy to manufacture and maintain. This invention uses mechanical linkage to achieve multi-dimensional adjustment of magnetic field direction and intensity, reducing manufacturing complexity and the risk of system failure. Furthermore, the clear layout of components and intuitive connection methods facilitate subsequent installation, maintenance, and replacement, improving the device's operability and practicality.

[0028] 4) Easy operation and high adjustment accuracy Each adjustment mechanism has a clear operating interface and physical limits, such as dial positioning, screw guide, and rotary insert ring switching functions, allowing users to achieve fine-grained adjustment and repeatable settings without the need for complex operating training, thereby improving the convenience of on-site use of the equipment.

[0029] 5) Wide range of applications, easy to promote and apply This ozone generating device has a modular structure and strong compatibility. It can be widely used in multiple application scenarios such as air purification, water disinfection, and medical disinfection. It has a good foundation for industrial promotion and technical extension capabilities. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Furthermore, the following description is for purposes of illustration and not limitation, and specific details, such as particular system structures and techniques, are provided to facilitate a thorough understanding of the embodiments of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0035] The present embodiment relates to an adjustable flat-plate magnetoelectric coupling ozone generator, and in particular, a flat-plate magnetoelectric coupling ozone generator in which both the magnetic field direction and magnetic field strength are adjustable. By arranging an adjustable magnetic field structure on the periphery of the ozone generating assembly 1, the device can satisfy the intensity adjustment of the magnetic field in all directions in which the ozone generating assembly 1 is located, namely, the axial magnetic field strength and the radial magnetic field strength. At the same time, the relative area and gap width of the discharge electrodes in the reaction chamber can also be adjusted, thereby significantly improving the ozone generation efficiency and control capability.

[0036] Reference Figures 1 to 3 The main body of the device includes an ozone generating assembly 1, which includes a shell 101 and a ground electrode 102 and a dielectric plate 103 fixedly installed therein. The dielectric plate 103 is provided with a high-voltage electrode 105 opposite to it, forming a discharge gap in an oxygen environment. The high-voltage electrode 105 is installed in the shell 101 so as to be axially rotatable and axially movable through an axial adjustment mechanism, and ozone is generated in an oxygen environment by utilizing the discharge gap between the electrodes.

[0037] The device is equipped with two sets of magnetic field adjustment systems, radial and axial. Specifically, the ozone generating assembly 1 is mirror-imaged with radial magnetic field adjustment components and axial magnetic field adjustment components on both sides. The radial magnetic field adjustment assembly includes a radial track base 4 and a helical base 3. The surface of the radial track base 4 is provided with six circumferentially equally spaced radial tracks, within which six magnets 2 are slidably disposed. The helical base 3 is mounted on the radial track base 4 and has spiral grooves corresponding to the radial tracks on its surface. The magnets 2 are mounted in the corresponding spiral grooves via magnet slides. Rotating the helical base 3 drives the magnets 2 to move equidistantly to achieve adjustment of the radial magnetic field strength. The axial magnetic field adjustment assembly includes a base 6 and an axial rail 23. The axial rail 23 is installed on the bed 22 through the rail base 10. The radial rail base 4 is installed on the base 6. The base 6 is driven by a ball screw mechanism to move axially back and forth on the axial rail 23, thereby adjusting the distance between the magnets 2 on the axis and realizing the adjustment of the axial magnetic field.

[0038] Referring to Figure 4 , the housing 101 of the ozone generating assembly 1 is provided with an air inlet 112 and an air outlet 111, located at the upper and lower ends of the housing 101, respectively. The ground electrode 102 is fixedly mounted on its inner wall, and the dielectric plate 103 is fixed to the inner end of the ground electrode 102. When power is applied to the ground electrode 102 and the high-voltage electrode 105, oxygen is introduced through the air inlet 112 of the housing 101. A chemical reaction occurs in the discharge gap between the dielectric plate 103 and the high-voltage electrode 105, producing ozone, which is then discharged through the air outlet 111 of the housing 101.

[0039] The axial adjustment mechanism includes an electrode rotating plate 106 mounted in cooperation with the outer shell 101, which can rotate axially without moving axially; a translation screw 108 is mounted at the axis of the electrode rotating plate 106, which can rotate axially relative to the electrode rotating plate 106 without moving axially relative to the electrode rotating plate 106; the inner end of the translation screw 108 is threadedly connected to the electrode translation plate 104, and the high-voltage electrode 105 is fixedly mounted on the electrode translation plate 104, and the electrode translation plate 104 and the electrode rotating plate 106 can move axially relative to each other without rotating axially relative to each other; an insert ring 109 is mounted at the outer end of the translation screw 108, as shown in Figures 10 and 11, which can move axially relative to the translation screw 108 without rotating axially relative to each other. When the insert ring 109 moves axially at the outer end of the translation screw 108 to engage or disengage with the electrode rotating plate 106, the relative area of ​​the discharge electrodes and the width of the discharge gap are adjusted respectively.

[0040] The translation screw 108 is inserted into the pin groove 110 via the pin 107 and is slidably matched with the electrode rotating plate 106 .

[0041] 12 , when the insert ring 109 is moved to engage with the electrode rotating plate 106 , and the insert ring 109 is rotated, the translation screw 108 , the electrode rotating plate 106 , the electrode translation plate 104 , and the high-voltage electrode 105 rotate together about the axis, thereby adjusting the relative area of ​​the discharge electrodes. When the insert ring 109 is moved to disconnect it from the electrode rotating plate 106, the insert ring 109 is rotated, and the translation screw 108 rotates axially, while the electrode rotating plate 106 and the electrode translation plate 104 do not rotate axially. The electrode rotating plate 106 and the translation screw 108 rotate axially relative to each other, and the rotation is converted into relative axial movement of the electrode translation plate 104 through the thread, thereby realizing the adjustment of the discharge gap width.

[0042] 7 , the surface of the radial track base 4 is provided with six circumferentially equally spaced radial tracks, and the six magnets 2 are respectively mounted on corresponding radial tracks and can slide radially in their respective radial tracks.

[0043] The helical base plate 3, as shown in Figures 8 and 9, is supported by two helical base plate bearings 5 ​​and mounted on the inner side of a radial track base 4. It engages with the slide of the magnets 2 via a spiral groove linkage structure. The magnet 2 structure is shown in Figures 5 and 6. Rotating the helical base plate 3 drives all magnets 2 to move synchronously along their respective radial tracks, maintaining an equidistant distribution. The radial position of the magnets 2 determines the strength of the radial magnetic field generated by the device.

[0044] Referring to Figure 2 , the ball screw mechanism includes a ball screw 9, a ball screw nut 8, and a screw nut seat 7. The ball screw 9 passes through the ball screw nut 8, which is fixedly connected to the screw nut seat 7. The screw nut seat 7 is fixedly connected to the base 6 via bolts. The outer end of the ball screw 9 is connected to a manual operating handle 11 via a coupling 12, and the inner end of the ball screw 9 is fixedly mounted on the bed 22 via a screw fixing end 13. The ozone generating assembly 1 is fixed to the upper middle portion of the ball screw 9 via a screw support seat 15 and a ball screw bearing 14.

[0045] When the operator turns handle 11, the ball screw 9 rotates about its axis, causing the ball screw nut 8 to move axially on the ball screw 9. Because the screw nut holder 7 is fixedly connected to the base 6, the magnets 2 remain in the same radial position while moving linearly along the axial track 23 along with the entire base 6 assembly. This changes the axial distance between each magnet 2 and the ozone generator assembly 1, thereby adjusting the axial magnetic field distribution intensity. The axial position change is continuous, and the position control accuracy is determined by the screw pitch and the rotation angle of handle 11.

[0046] 3 , a track slider 21 is provided at the bottom of the base 6 and is mounted on an axial track 23 to limit the freedom of movement of the base 6 in the axial direction and provide linear guide support. The radial track base 4 is provided on the base 6 and fixed thereto by bolts.

[0047] The shell base 17 of the ozone generating assembly 1 is connected to support shafts 19 on both sides. The support shaft 19 is installed in the support 16 through support bearings 18 provided at both ends to realize axial rotation function; one side of the support shaft 19 is connected to the support handle 24 through the support connection mechanism 25, and the other side of the support shaft 19 is installed on the dial 20; when the support handle 24 is rotated, the support shaft 19 drives the shell base 17 to rotate around the axis as a whole to adjust the angle between the discharge gap direction and the axial magnetic field direction in the ozone generating assembly 1.

[0048] The rotation angle is read via the scale plate 20. This structure can adjust the angle between the magnetic field direction and the electrode arrangement without changing the position of the magnet 2 or affecting the original function of the radial and axial magnetic field intensity adjustment mechanism.

[0049] The second embodiment of the present invention relates to an operating method of an adjustable flat-plate ozone generator, which mainly includes the following contents: 1. Initial preparation and system startup Gas access: Air or air-oxygen mixture is accessed through the air inlet 112 of the housing 101, wherein the oxygen content is 23%-99%. The air inlet flow rate is adjusted to 1.0-3.0 L / min. The air outlet 111 is connected to the ozone collection device.

[0050] Power supply: Connect the ground electrode 102 and the high-voltage electrode 105 to a high-frequency high-voltage power supply (frequency 5.0-15.0 Hz, voltage 5.5-8.0 kV) to form a discharge electric field.

[0051] 2. Radial magnetic field strength adjustment Positioning the helix base 3: Confirm that the bearings of the helix base 3 and the radial track base 4 are installed in place and there is no jamming when rotating the base.

[0052] Synchronous adjustment of magnets 2: Rotate the helical base plate 3 clockwise to drive the six magnets 2 to slide synchronously outward along the radial track through the spiral grooves on the bottom surface, and the radial magnetic field strength is weakened; rotate counterclockwise to retract the magnets 2 and strengthen the magnetic field.

[0053] Precision control: Observe the scale on the magnet 2 slide (each scale corresponds to a magnetic field strength of 0.1mT). For example, if the base plate is rotated 90° from the initial position and the magnet is displaced 5mm in the radial direction, the magnetic field strength increases from 0.5mT to 0.8mT.

[0054] 3. Axial magnetic field strength adjustment Handle drive: The manual handle 11 is rotated at a constant speed, which drives the ball screw 9 to rotate through the coupling 12, and the ball screw nut 8 moves axially.

[0055] Base 6 drives magnet 2 along axial track 23, increasing the axial magnetic field as it approaches ozone generator assembly 1 and decreasing as it moves away. For example, if manual handle 11 rotates 2 times (screw pitch 1mm), base 6 moves 2mm axially, and the magnetic field strength changes by 0.2mT.

[0056] Position locking: After adjusting to the target position, the ball screw 9 is fixed by the locking nut at the fixed end 13 of the screw to prevent displacement.

[0057] 4. Discharge electrode parameter adjustment (dual function switching) Electrode area adjustment: Push the insert ring 109 axially inward to engage with the electrode rotating plate 106; Rotating the insert ring 109 drives the translation screw 108, the electrode rotating plate 106 and the high-voltage electrode 105 to rotate synchronously through the pin 107. For example, if the rotation is 30° clockwise, the coverage area of ​​the high-voltage electrode 105 and the ground electrode 102 increases from 80% to 95%.

[0058] Gap width adjustment: Pull the insert ring 109 out axially to disconnect it from the electrode rotating plate 106; By rotating the insert ring 109, the translation screw 108 rotates independently, and the electrode translation plate 104 moves axially through the screw drive. For example, if it rotates counterclockwise for one turn (pitch 0.5mm), the discharge gap decreases from 2mm to 1.5mm.

[0059] 5. Magnetic angle adjustment Rotate the support handle 24: Turn the support handle 24 clockwise, the support shaft 19 drives the housing base 17 to rotate, and the angle between the discharge gap direction and the axial magnetic field increases; Angle reading: The rotation angle is read in real time through the dial 20. For example, when adjusting from 0° to 45°, the ozone production rate is observed to increase by 12%; Fixed angle: After adjustment, tighten the positioning bolts of the support bearing 18 to prevent the angle from shifting.

[0060] 6. Operation monitoring and parameter optimization Real-time monitoring: The ozone concentration at the air outlet 111 is monitored by an ozone concentration detector (external), which should be stable at 800ppm during normal operation; Dynamic adjustment: If the ozone production rate decreases due to increased gas humidity, the radial magnetic field strength can be increased (+0.2mT) and the discharge gap can be reduced (-0.3mm) to maintain a stable concentration. Shutdown sequence: first cut off the high voltage power supply, then close the oxygen inlet 112, and finally stop the operation of the magnetic field adjustment mechanism.

[0061] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention, and should all be included in the scope of protection of the present invention.
