Description

Technical Field

[0001] This utility model relates to the field of ozone electrolysis technology, specifically to an electrolytic ozone generator. Background Technology

[0002] Ozone water, as a green and environmentally friendly high-efficiency disinfectant, is mainly prepared using a low-voltage electrolysis method. This method employs boron-doped diamond electrodes and a solid electrolyte membrane for electrolytic reaction. While boron-doped diamond electrodes possess excellent chemical properties, in practical applications, ensuring the physical protection of the electrodes and the stability of the water flow is difficult. Existing electrolytic cell structures often focus on heat dissipation, ease of disassembly and assembly, elimination of air blockage, and extended lifespan, but neglect the following issues: First, the electrode sheets are prone to breakage due to direct impact from the water flow. Second, inaccurate water flow control increases the risk of dry burning. The inlet of the ozone generator's electrolytic cell often adopts a direct-flow design, where high-pressure water directly impacts the brittle boron-doped diamond electrode sheets without buffering. Long-term operation can easily cause micro-cracks or even breakage of the electrodes. Since the electrode assembly is connected to the housing as a whole, it needs to be replaced as a whole after damage, increasing operating costs. Especially in compact equipment for preparing high-concentration ozone water, electrode damage or dry burning failure is more likely due to impact on the electrodes and inaccurate water flow control. Utility Model Content

[0003] The purpose of this invention is to provide an electrolytic ozone generator that solves the problems of electrodes being easily damaged by water flow and inaccurate flow monitoring leading to dry burning in existing water electrolysis ozone generators.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0005] An electrolytic ozone generator includes a housing, an electrode assembly, and a tank cover. The housing includes an inlet, an outlet, and an electrolytic cell. The electrolytic cell penetrates one end of the housing to form an opening. The tank cover is disposed on the opening. The inlet and outlet are respectively disposed at both ends of the housing and are connected to the electrolytic cell. A partition structure is provided inside the electrolytic cell. The partition structure is positioned opposite the inlet, so that the incoming water flow is slowed down before entering the electrolytic cell. The electrode assembly is disposed inside the electrolytic cell. Pressurized water entering the electrolytic cell from the inlet is blocked by the partition structure and bends, reducing the impact force of the water flow before entering the electrolytic cell. This reduces the instantaneous impact force of the water flow directly hitting the electrodes, protecting the electrode assembly and extending its service life.

[0006] Furthermore, the electrode assembly includes an electrode support, a first electrode plate, a proton exchange membrane, and a second electrode plate. One end of the electrode support is connected to the tank cover. The first electrode plate, the proton exchange membrane, and the second electrode plate are stacked in sequence and then connected to the other end of the electrode support. Electrolysis of water generates ozone, and the ozone dissolves in water to form ozone water for disinfection.

[0007] Furthermore, the electrode assembly also includes a clamping plate and a fixing member. The clamping plate is connected to the outside of the first electrode plate and the second electrode plate by the fixing member. The clamping plate and the fixing member are made of titanium metal, which protects the electrode plates and has strong corrosion resistance, thus extending their service life.

[0008] Preferably, the first electrode is a boron-doped diamond electrode, which has high efficiency in producing ozone through electrolysis and produces no toxic side effects.

[0009] Furthermore, the groove cover has a groove on its outward-facing side, and a mounting hole is provided at the bottom of the groove. One end of the electrode bracket passes through the mounting hole and is fixed in the groove. The electrode assembly also includes a sealing ring, which is fitted onto the electrode bracket and seals the gap between the electrode bracket and the mounting hole, adjusting the pressure on the electrode sheet and preventing breakage.

[0010] Furthermore, it also includes a flow sensor, which is mounted on the housing and used to detect the flow rate of water entering the electrolytic cell.

[0011] Furthermore, the flow sensor includes a water turbine and a signal conversion module. The water turbine is disposed inside the water inlet, and the signal conversion module is disposed on the housing. The signal conversion module detects the rotational speed of the water turbine through magnetic induction, which accurately detects the flow rate, prevents leakage, and has a long service life.

[0012] Preferably, the first electrode sheet and the second electrode sheet are provided with multiple through holes to improve the efficiency of ozone production by electrolysis.

[0013] Furthermore, the partition structure includes a reversing baffle and a partition. The partition is disposed in the electrolytic cell along the water flow direction. The reversing baffle is disposed at both ends of the partition. The reversing baffle is opposite to the water inlet and the water outlet, respectively. A water flow channel is provided between the reversing baffle and the water inlet and the water outlet for water flow to be diverted and the water flow direction is guided.

[0014] Preferably, the electrolytic cell includes a first cell and a second cell, which are formed by the partition structure separating the electrolytic cell. Both the first cell and the second cell are connected to the inlet and the outlet. The electrode assembly is provided in both the first cell and the second cell to disperse the water flow, ensure the efficiency of electrolysis, and reduce the impact of water flow.

[0015] The beneficial effects of this utility model are as follows:

[0016] (1) The electrolytic ozone generator is equipped with a partition structure set inside the electrolytic cell and opposite to the water inlet. This forces the high-pressure water flow to turn when entering the electrolytic cell. The impact force of the water flow is reduced before it enters the electrolytic cell, which significantly reduces the instantaneous impact force of the water flow directly hitting the electrode and protects the brittle boron-doped diamond electrode sheet. After passing through the partition structure, the water flow diffuses smoothly into the electrolytic cell, avoiding the generation of micro-cracks or fractures in the electrode due to long-term hydraulic impact. This extends the service life of the electrode assembly and reduces maintenance costs caused by electrode damage. The electrode assembly is connected to the cell cover and installed inside the electrolytic cell, which facilitates replacement after damage and avoids the need for complete replacement, thus saving costs.

[0017] (2) The electrolytic ozone generator has a water flow turbine installed inside the water inlet and a magnetic induction signal conversion module on the housing. It can capture changes in water flow speed in real time and convert them into electrical signals. It can accurately obtain water flow data and link the power supply system of the electrode assembly. When the water flow is interrupted or the flow rate is lower than the threshold, the current of the first electrode plate and the second electrode plate is cut off to prevent dry burning. The water flow turbine and the signal conversion module transmit water flow signals through magnetic induction to prevent leakage. Attached Figure Description

[0028] Example 1

[0029] like Figures 1-7 As shown, this embodiment discloses an electrolytic ozone generator, including a housing 1, an electrode assembly 2, and a tank cover 3. The housing 1 includes an inlet 11, an outlet 15, and an electrolytic cell. The electrolytic cell penetrates one end face of the housing 1 to form an opening, and the tank cover 3 is disposed on the opening. The inlet 11 and the outlet 15 are respectively disposed at both ends of the housing 1, and both the inlet 11 and the outlet 15 are connected to the electrolytic cell. A partition structure 18 is provided inside the electrolytic cell. The partition structure 18 is configured to face the inlet 11, so that the incoming water flow is slowed down before entering the electrolytic cell. The electrode assembly 2 is disposed inside the electrolytic cell, and one end of the electrode assembly 2 is connected to the tank cover 3. The partition structure 18 in the electrolytic cell can reduce the impact of water flow and water pressure on the electrode assembly 2, reduce the risk of damage to the electrode assembly 2, and also change the direction of the incoming water flow, so that the water volume in the electrolytic cell is sufficient, improving the efficiency of ozone generation by electrolysis, preventing the electrode assembly 2 from burning dry due to instantaneous overpressure, and extending the overall service life.

[0030] Furthermore, the electrode assembly 2 includes an electrode support 21, a first electrode sheet 23, a proton exchange membrane 24, and a second electrode sheet 25. One end of the electrode support 21 is connected to the tank cover 3. The first electrode sheet 23, the proton exchange membrane 24, and the second electrode sheet 25 are stacked in sequence and connected to the other end of the electrode support 21. This assembly is used to directly contact water to generate ozone water. It has high electrolysis efficiency and no by-products are generated. The ozone water is also highly safe to use.

[0031] Preferably, the electrode assembly 2 further includes a clamping piece 26 and a fixing member 22. The clamping piece 26 is connected to the outside of the first electrode piece 23 and the outside of the second electrode piece 25 by the fixing member 22, clamping the two electrode pieces. The clamping piece 26 and the fixing member 22 are made of titanium metal, which provides stable clamping, corrosion resistance, and long service life.

[0032] More preferably, the first electrode 23 is a boron-doped diamond electrode, which has an ultra-wide electrochemical window; corrosion resistance and zero electrode consumption; no corrosion in strong oxidizing electrolytes, avoiding the dissolution of metal ions and pollution of water quality, and a long service life; low oxygen evolution side reaction activity; and high ozone electrolysis efficiency.

[0033] Preferably, the groove 31 is provided on the outward side of the groove cover 3, and the mounting hole 32 is provided at the bottom of the groove 31. One end of the electrode bracket 21 passes through the mounting hole 32 and is fixed in the groove 31. The electrode assembly 2 also includes a sealing ring 27, which is sleeved on the electrode bracket 21 and seals the gap between the electrode bracket 21 and the mounting hole 32. This is used to adjust the pressure on the electrode sheet and prevent excessive pressure from damaging the electrode sheet.

[0034] Furthermore, it also includes a flow sensor, which is installed on the housing 1 to detect the amount of water entering the electrolytic cell, control the concentration of ozone water generated, and prevent the electrode plates from drying out.

[0035] Furthermore, the flow sensor includes a water turbine 6 and a signal conversion module 5. The water turbine 6 is installed inside the water inlet 11, and the signal conversion module 5 is installed on the housing 1. The signal conversion module 5 detects the rotation speed of the water turbine 6 through magnetic induction. The water turbine 6 is directly driven to rotate by the incoming water. The signal conversion module 5 reads the rotation speed of the water turbine 6 through magnetic induction and then converts the rotation speed into a water flow signal. The current on the electrode assembly 2 is controlled by the water flow signal, which helps to prevent dry burning.

[0036] Preferably, the first electrode plate 23 and the second electrode plate 25 are provided with multiple through holes to increase the contact area between the electrode plates and water and improve the efficiency of ozone production by electrolysis.

[0037] Further, see Figure 7The partition structure 18 includes a reversing baffle and a partition. The partition is arranged in the electrolytic cell along the water flow direction. The reversing baffle is arranged at both ends of the partition. The reversing baffle is opposite to the inlet 11 and the outlet 15 respectively. A water flow channel is provided between the reversing baffle and the inlet 11 and the outlet 15 for water flow. The water flows into the electrolytic cell through the axial direction of the inlet 11 and is blocked by the partition structure 18. The water then turns and enters the electrolytic cell along the inner wall of the tank cover 3. After electrolysis, the water flows out through the outlet 15.

[0038] Preferably, it also includes a sealing structure 4, which includes a convex ring disposed on the lower end face of the tank cover 3 and a groove disposed on the edge of the opening of the housing 1. A sealing ring is provided in the groove, and the sealing structure 4 serves to prevent water leakage from the electrolytic cell.

[0039] The working process of this electrolytic ozone generator is as follows:

[0040] Water flows into the housing 1 through the inlet 11. The water flows along the axial direction of the housing 1 and is blocked by the partition structure 18, causing it to turn and decelerate after contacting the inner wall of the electrolytic cell. The water flow at the inlet 11 drives the water turbine 6 to rotate. After the signal conversion module 5 receives the water full signal, the electrode assembly 2 is energized to electrolyze the water entering the electrolytic cell to generate ozone. The ozone dissolves in the water to form ozone water. After the ozone water reaches the required concentration, it flows out of the electrolytic cell through the outlet 15 for use by external equipment.

[0041] Example 2

[0042] This embodiment also discloses an electrolytic ozone generator, including a first tank 12 and a second tank 13. The first tank 12 and the second tank 13 are formed by separating the electrolytic cells by a partition structure 18. Both the first tank 12 and the second tank 13 are connected to the inlet 11 and the outlet 15. Electrode assemblies 2 are provided in both the first tank 12 and the second tank 13. The first tank 12 and the second tank 13 are parallel and located on the left and right sides of the partition structure 18. The tops of the first tank 12 and the second tank 13 are connected, which can mix the ozone generated after electrolysis to ensure that the ozone concentration in the ozone water is uniform.

[0043] Furthermore, it also includes a third electrolytic cell 16 and a fourth electrolytic cell 17. The third electrolytic cell 16 and the fourth electrolytic cell 17 are symmetrically distributed with the first tank 12 and the second tank 13 with the center plane of the partition structure 18 as the reference, dividing the interior of the shell 1 into four equal parts. The third electrolytic cell 16 and the fourth electrolytic cell 17 are equipped with separate electrode assemblies 2, which can improve the efficiency of ozone production by electrolysis of water and ensure that each electrode assembly 2 works independently and stably.

[0044] Preferably, a separator 33 is provided on the bottom wall of the groove 31. The separator 33 separates the internal space of the groove 31 to prevent the external lines of the electrode assembly 2 from interfering with each other and short-circuiting, thereby improving the safety of the internal circuit.

[0045] Preferably, mounting grooves 14 are provided at both the upper and lower parts of the housing 1, and a signal conversion module 5 is installed in the mounting groove 14 to control the electrode assembly 2 in the upper and lower electrolysis cells to perform electrolysis, thereby more accurately controlling the flow rate of generated ozone water.

[0046] This electrolytic ozone generator has a modular structure and can be connected to different disinfection equipment.
