Description

Technical Field

[0001] This utility model relates to the field of water-gas separation technology, specifically to a water-gas separation device and an ozone generator using the same. Background Technology

[0002] Ozone water is a green, environmentally friendly, and highly effective oxidizing disinfectant with no toxic byproducts. Current ozone production primarily utilizes low-to-medium voltage electrolysis, which is characterized by its wide applicability and high efficiency. This method employs boron-doped diamond sheets and cation exchange membranes to complete the electrolysis reaction. However, the resulting ozone water contains a large number of ozone and hydrogen bubbles. While more efficient, with higher solubility, and safer to use than ozone produced by aeration or high-voltage corona discharge, it still suffers from intermittent water output and unstable ozone generation. Therefore, the generated ozone water needs to be treated to remove the bubbles. Currently used water-gas separation devices are mostly designed for aeration or high-voltage corona discharge methods and are ineffective and unsuitable for separating microbubbles generated by low-voltage electrolysis.

[0003] The existing patent publication number CN22092592U mentions using ultrasound for bubble breaking. However, this method accelerates the decomposition of ozone molecules due to high-frequency vibration, significantly reducing the effective concentration of ozone water. It also carries the risks of high energy consumption, noise pollution, and mechanical failure, affecting not only equipment reliability but also reducing the disinfection ability of ozone water. Therefore, there is a need for a water-gas separation device that is physically driven, requires external energy input, and can maintain ozone stability. Utility Model Content

[0004] One of the objectives of this invention is to provide a water-gas separation device that solves the problem that existing water-gas separation devices require energy and are prone to structural failures during long-term use, leading to separation failure.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0006] A water-gas separation device includes a water-gas separation chamber and an inlet / outlet connector. The water-gas separation chamber has an exhaust end and an inlet / outlet end at its two ends, respectively. The inlet / outlet connector is connected to the inlet / outlet end. A floating valve core is provided inside the water-gas separation chamber. The floating valve core moves up and down inside the water-gas separation chamber. When the floating valve core moves to the bottom of the water-gas separation chamber, it closes the inlet / outlet end. When the floating valve core moves to the top of the water-gas separation chamber, it closes the exhaust end. Water-gas separation is performed without external energy supply and does not adversely affect the solubility of ozone.

[0007] Furthermore, the inlet / outlet water connector includes an inlet pipe, a drain pipe, and a buffer chamber. The inlet pipe extends into the buffer chamber and can form a closed fitting connection with the lower part of the floating valve core. One end of the drain pipe is connected to the bottom of the buffer chamber, and water and gas are separated due to their different densities.

[0008] Furthermore, the floating valve core includes a float, an upper valve needle, and a lower valve needle. The upper valve needle and the lower valve needle are respectively connected to the upper and lower ends of the float. The float has a cavity inside. When the floating valve core moves to the top of the water-air separation chamber, the upper valve needle closes the exhaust end; when the floating valve core moves to the bottom, the lower valve needle closes the inlet and outlet ends. The water inlet and exhaust can be controlled by the up and down movement of the float.

[0009] Furthermore, the water-air separation chamber is provided with a guide part, and the floating valve core slides in cooperation with the guide part to make the floating valve core move up and down stably.

[0010] Furthermore, the floating valve core also includes a stabilizing ring, which is disposed on the outer wall of the float to improve the stability of the exhaust action and reduce exhaust noise.

[0011] Preferably, the system also includes a housing, which comprises an upper shell and a lower shell, which are combined to form the housing. The water-air separation chamber is disposed within the housing for easy disassembly, assembly, maintenance, and use.

[0012] Furthermore, it also includes a filter device connected to the exhaust end for filtering gas.

[0013] Preferably, the filtration device has a filter layer filled with activated carbon to filter out impurities in the extracted gas and prevent pollution and odor diffusion.

[0014] Preferably, the filter device is also equipped with a gas probe for detecting the composition of the discharged gas.

[0015] One of the purposes of this invention is to provide an ozone generator that solves the problem of ozone bubbles and secondary bubbles in the generated ozone water.

[0016] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0017] An ozone generator includes the aforementioned water-gas separation device for separating impurity gases from ozone water.

[0018] The beneficial effects of this utility model are as follows:

[0019] (1) The water-gas separation device achieves gas-liquid separation through a mechanical structure in the water-gas separation chamber of the floating valve core that floats with the water level: when the water level rises, the upper valve needle on the floating valve core closes the exhaust end to prevent gas from escaping; when the water level falls, the lower valve needle closes the inlet and outlet ends to intercept air bubbles from seeping in. It uses the density of water and gas for separation. Compared with ultrasonic forced bubble breaking technology that uses high-frequency vibration to decompose ozone molecules, this device has no energy disturbance throughout the process through physical isolation, and the solubility of ozone water can be kept stable. Compared with ultrasonic equipment that relies more on continuous power input, the buoyancy adaptive mechanism achieves zero external energy drive, completely avoiding vibration failures such as electrode damage and seal failure, and effectively improving the life of the equipment.

[0020] (2) The water-gas separation device is connected to a filter device at the outlet of the water-gas separation chamber. The filter device can filter the discharged gas to prevent the impurities generated by electrolysis from being released directly to the outside, causing pollution and odor, which would affect the use.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0028] Example 1

[0029] like Figures 1-4 As shown, this embodiment discloses a water-gas separation device, including a water-gas separation chamber 1 and an inlet / outlet connector 3. The water-gas separation chamber 1 has an exhaust end 14 and an inlet / outlet end 15 at its two ends, respectively. The inlet / outlet connector 3 is connected to the inlet / outlet end 15. A floating valve core 4 is provided in the water-gas separation chamber 1. The floating valve core 4 moves up and down in the water-gas separation chamber 1. When the floating valve core 4 moves to the bottom of the water-gas separation chamber 1, it closes the inlet / outlet end 15. When the floating valve core 4 moves to the top of the water-gas separation chamber 1, it closes the exhaust end 14. When the water level in the water-gas separation chamber 1 rises, the upper valve needle 42 on the floating valve core 4 closes the exhaust end 14 to prevent gas escape. When the water level drops, the lower valve needle 43 closes the inlet / outlet end 15 to intercept air bubbles from seeping in. It uses the density of water and gas for separation, which does not require external power supply and does not reduce the solubility of ozone in water.

[0030] Furthermore, the inlet / outlet connector 3 includes an inlet pipe 31, a drain pipe 32, and a buffer chamber 33. The inlet pipe 31 extends into the buffer chamber 33 and forms a closed fitting connection with the lower part of the floating valve core 4. One end of the drain pipe 32 is connected to the bottom of the buffer chamber 33. The buffer chamber 33 is used for buffering ozone water after it enters and for separating ozone water from gas. Separation is achieved by utilizing the density of water and gas, without the need for external power supply and without causing a decrease in the concentration of ozone water.

[0031] Furthermore, the floating valve core 4 includes a float 41, an upper valve needle 42, and a lower valve needle 43. The upper valve needle 42 and the lower valve needle 43 are respectively connected to the upper and lower ends of the float 41. The float 41 has a cavity 45. When the floating valve core 4 moves to the top of the water-air separation chamber 1, the upper valve needle 42 closes the exhaust end 14. When the floating valve core 4 moves to the bottom, the lower valve needle 43 closes the inlet and outlet water ends 15. By controlling the volume of the cavity 45 in the float 41, the exhaust frequency and exhaust volume of the floating valve core 4 can be controlled, thereby stabilizing the exhaust.

[0032] Furthermore, the water-air separation chamber 1 is provided with a guide part 11, and the floating valve core 4 slides with the guide part 11 to constrain the direction of the floating valve core 4 to move up and down, thereby achieving stable control of the opening and closing state. Specifically, the guide part 11 is a ring set at the inlet and outlet water end 15, and the lower valve needle 43 of the floating valve core 4 is fitted with the ring.

[0033] Preferably, the floating valve core 4 further includes a stabilizing ring 44, which is disposed on the outer wall of the float 41. The stabilizing ring 44 protrudes from the wall of the floating valve core 4, weakening the internal turbulence, improving the stability of exhaust and ventilation, and reducing vibration.

[0034] Preferably, it also includes a housing 12, which includes an upper housing 121 and a lower housing 122. The upper housing 121 and the lower housing 122 are combined to form the housing 12. The water-air separation chamber 1 is disposed inside the housing 12. The upper housing 121 and the lower housing 122 are connected by a flange structure formed by multiple bolts, which facilitates disassembly and maintenance.

[0035] Furthermore, it also includes a filter device 2, which is connected to the exhaust end 14 and can prevent pollution and odors.

[0036] Preferably, the filter device 2 is provided with a filter layer 21, which is filled with one or more of activated carbon, ethylene fluoride, polypropylene and glass fiber, so as to filter out the by-products generated by electrolysis of water and prevent the spread of odors from affecting use and polluting the environment.

[0037] Preferably, the filter device 2 is also provided with a gas probe 22, which is located at the connection between the water inlet of the filter device 2 and the exhaust end 14 of the water-gas separation chamber 1, and can detect whether gas passes through and the type of gas.

[0038] More preferably, a thread 13 is provided on the outer wall at the lower end of the housing 12 for connecting the inlet / outlet water connector 3.

[0039] The working process of this water-air separator is as follows:

[0040] When no water enters the inlet pipe 31, the floating valve core 4 in the water-gas separation chamber 1 remains at the bottom of the chamber due to its own gravity. The lower valve needle 43 closes the inlet pipe 31. At this time, the exhaust end 14 of the water-gas separation chamber 1 is open. When the ozone water generated by the ozone generator enters the buffer chamber 33 from the inlet pipe 31, the gas in the ozone water will gradually move upwards in the buffer chamber 33, and the gas will rise and pass through the exhaust end 14 and the filter device 2 in sequence before being discharged. After the water fills the buffer chamber 33, the ozone water will be discharged. Oxygenated water will be discharged from the drain pipe 32 of the inlet / outlet water connector 3; when the water flow fills the water-gas separation chamber 1, the floating valve core 4 will move to the top of the water-gas separation chamber 1 under the action of buoyancy, and the exhaust end 14 of the upper valve needle 42 will be closed. When the gas pressure in the water-gas separation chamber 1 gradually accumulates and exceeds the buoyancy, the water level in the water-gas separation chamber 1 will drop under the action of gas pressure, and the floating valve core 4 will also drop, driving the upper valve needle 42 to open the exhaust end 14, and the gas accumulated in the water-gas separation chamber 1 will be discharged outward.

[0041] Example 2

[0042] This embodiment also discloses an ozone generator, including a water-gas separation device and an ozone generator. The two ends of the water inlet pipe 31 on the water-gas separation device are connected to the ozone generator and the water-gas separation chamber 1, respectively. The ozone water generated by the electrolysis of the ozone generator is introduced into the water-gas separation chamber 1, and after being vented, it is discharged to the outside through the drain pipe 32. The ozone generator uses boron-doped diamond electrodes to electrolyze water to generate ozone water, which has the advantages of high electrolysis efficiency and no toxic byproduct generation.

[0043] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and any modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
