Description

Technical Field

[0001] This application relates to the field of gas-water mixing technology, and in particular to a split-flow ozone gas-water mixing structure. Background Technology

[0002] An ozone generator is a device used to produce ozone gas (O3). Because ozone decomposes easily and cannot be stored for long periods, it usually needs to be generated and used on-site. Therefore, ozone generators are required wherever ozone is used. Ozone generators are widely used in drinking water, wastewater treatment, industrial oxidation, food processing and preservation, pharmaceutical synthesis, and space sterilization. The ozone gas produced by an ozone generator can be used directly or mixed with liquids using a mixing device.

[0003] When using ozone gas, it is usually mixed with water to generate ozonated water before use. Existing ozone generators typically require placement in a water container, where the water is electrolyzed to produce ozone gas. The ozone gas then diffuses and mixes with the water to form ozonated water. However, this method suffers from uneven mixing, and the limited container volume restricts the flow rate of ozone water produced per cycle. Utility Model Content

[0004] The main objective of this application is to propose a split-flow ozone-water mixing structure, which aims to solve the problems of uneven mixing of ozone and water and the limited amount of ozone and water produced in a single operation.

[0005] To achieve the above objectives, the present application proposes a diversion-type ozone-water mixing structure, comprising: a main body, with an inlet pipe and an outlet pipe respectively connected at both ends of the main body; an ozone module for generating ozone disposed inside the main body; multiple parallel ozone channels disposed inside the main body corresponding to both sides of the ozone module, all of which are connected to the ozone module; water flow channels disposed inside the main body corresponding to both sides of the ozone module, which are parallel to the ozone channels and not connected to the ozone module; and the ends of the multiple ozone channels and the ends of the water flow channels respectively connected to the inlet pipe and the outlet pipe.

[0006] Optionally, the ozone module includes a proton exchange membrane, with electrode plates attached to both sides of the proton exchange membrane and a charging plate attached to the side of the electrode plates.

[0007] Optionally, the electrode sheet is provided with a plurality of first through slots evenly distributed along a straight line, and the power supply sheet is provided with a second through slot at each of the first through slots.

[0008] Optionally, both the first through slot and the second through slot are rectangular structures, and the width of the second through slot is greater than the width of the first through slot.

[0009] Optionally, both of the power supply plates are provided with a connecting portion extending out of the main body, the connecting portion being used to connect to an external power source.

[0010] Optionally, the main body is a cylindrical structure, and the main body is symmetrically divided into a first part and a second part with a semi-circular cross section about the ozone module.

[0011] Optionally, the first part is provided with a plurality of pins on the surface for connecting with the second part, and the second part is provided with a plurality of pin holes on the surface for connecting with the first part, each corresponding to a pin position.

[0012] Optionally, a fixing sleeve is fitted on the outer side of the main body near both ends.

[0013] Optionally, an annular limiting block is provided on the main body between the two fixed sleeves. The limiting block is integrally formed with the main body, and the two fixed sleeves abut against the two ends of the limiting block respectively.

[0014] Optionally, the cross-section of the ozone channel is a semi-circular structure, and the two ends of the main body are provided with funnel-shaped through holes corresponding to the ozone channel. The end with the smaller diameter of the through hole is connected to the corresponding ozone channel.

[0015] This application's technical solution involves a main body with an inlet and outlet pipe connected at both ends. An ozone module for generating ozone is housed inside the main body. Multiple parallel ozone channels are arranged on both sides of the ozone module, all communicating with the ozone module. Water flow channels are also arranged on both sides of the ozone module, parallel to the ozone channels but not communicating with the ozone module. The ends of the ozone channels and the ends of the water flow channels are connected to the inlet and outlet pipes, respectively. Water flows in from the inlet pipe and splits into two paths: one part enters the outlet pipe through the water flow channel, and the other part enters the ozone channel. The ozone module electrolyzes the water to generate ozone, which is then injected into the ozone channel, thus creating an ozone-containing environment. Water enters the outlet pipe through the ozone channel, and the ozone water passing through the ozone channel mixes rapidly with the water passing through the water flow channel as it enters the outlet pipe. Multiple ozone and water flow channels divert the water entering the main body. The parallel arrangement of multiple ozone channels disperses the water flow and increases the contact area with the ozone module, thereby increasing the contact between ozone gas and water and improving the mixing efficiency. Furthermore, by first diverting the water and then recombining it, the water flow speed is changed, ensuring sufficient contact between ozone gas and water, thus improving the uniformity of mixing. This design allows water to flow through the main body, generating ozone gas during the water flow process, enabling the flowing water to mix rapidly with the ozone gas, effectively improving the ozone water production efficiency.

[0029] When using ozone gas, it is usually mixed with water to generate ozonated water before use. Existing ozone generators typically require placement in a water container, where the water is electrolyzed to produce ozone gas. The ozone gas then diffuses and mixes with the water to form ozonated water. However, this method suffers from uneven mixing, and the limited container volume restricts the flow rate of ozone water produced per cycle.

[0030] In view of this, this application proposes a split-flow ozone-water mixing structure.

[0031] In the embodiments of this application, reference is made to Figures 1 to 4The aforementioned diversion-type ozone-water mixing structure includes: a main body 1, with an inlet pipe and an outlet pipe connected to both ends of the main body 1, an ozone module installed inside the main body 1, and multiple parallel ozone channels 140 arranged on both sides of the ozone module inside the main body 1, all of which are connected to the ozone module; water flow channels 150 arranged on both sides of the ozone module inside the main body 1, which are parallel to the ozone channels 140 and are not connected to the ozone module; the cross-sectional area of ​​the water flow channels 150 is larger than that of the ozone channels 140; and the inlet pipe and outlet pipe are connected to both ends of the multiple ozone channels 140 and the water flow channels 150, respectively.

[0032] Specifically, water flows in from the inlet pipe and is divided into two paths: one part enters the outlet pipe through the water flow channel 150, and the other part enters the ozone channel 140. The ozone module electrolyzes the water to generate ozone and injects it into the ozone channel 140, allowing the ozone-containing water to enter the outlet pipe through the ozone channel 140. Finally, the ozone-rich water passing through the ozone channel 140 mixes rapidly with the water passing through the water flow channel 150 as they enter the outlet pipe. The water entering the main body 1 is diverted through multiple ozone channels 140 and water flow channels 150, arranged in parallel. Multiple ozone channels 140 disperse the water flow and increase the contact area with the ozone module, while also increasing the contact between ozone gas and water, thereby improving the mixing efficiency of ozone gas and water. In addition, by first splitting the water and then merging it, the speed of the water flow is changed, and the ozone gas is allowed to come into full contact with the water, thereby improving the uniformity of mixing. This design allows the water to flow through the main body 1 and generate ozone gas during the water flow, enabling the flowing water to mix with the ozone gas quickly, which can effectively improve the generation efficiency of ozone water.

[0033] In this embodiment, the ozone module includes a proton exchange membrane 210, with electrode plates 220 respectively attached to both sides of the proton exchange membrane 210. The electrode plates 220 are BDD electrode plates 220, and charging plates 230 are attached to the sides of the electrode plates 220. The main function of the proton exchange membrane 210 is selective permeation, allowing only H+ to pass through, thereby maintaining the charge balance between the anode and cathode. One of the charging plates 230 is connected to the positive electrode, and the other is connected to the negative electrode. When the charging plate 230 is energized, it supplies power to the corresponding electrode plate 220 and electrolyzes water to produce ozone.

[0034] In this embodiment, a plurality of first through slots 221 are uniformly formed along a straight line on the electrode plate 220, and a second through slot 231 is formed on the electrode plate 230 at the corresponding positions of the first through slots 221. The first through slots 221 and the second through slots 231 form channels for water flow and ozone passage. Water flows through the second through slots 231 of the electrode plate 230 and the first through slots 221 of the electrode plate 220, and comes into contact with the surface of the proton exchange membrane 210, promoting the electrolysis reaction. The through slot design increases the contact area between the water flow and the electrode plate 220, optimizes ion transport during the electrolysis process, and the uniformly distributed through slots disperse the water flow, improving the electrolysis stability.

[0035] In this embodiment, both the first channel 221 and the second channel 231 are rectangular structures. The width of the second channel 231 is greater than the width of the first channel 221. The long side of the first channel 221 is perpendicular to the axis of the ozone channel 140, which increases the fluid shear force. The second channel 231 is larger than the first channel 221, which creates a pressure difference when the water flows through, enhances the turbulence effect, promotes the mixing of ozone and water, and improves the ozone dissolution rate.

[0036] In this embodiment, each of the two power supply plates 230 is provided with a connecting part 232 extending out of the main body 1. The connecting part 232 is used to connect to an external power source. The connecting part 232 of the power supply plate 230 extends out of the main body 1 and is connected to an external power source to supply power to the electrode plate 220. The external power source provides DC power to drive the ozone module electrolysis reaction.

[0037] Specifically, in order to remove scale from the electrode surface, the polarity of the electrodes (positive and negative) can be switched periodically, so that the original cathode becomes the anode and the anode becomes the cathode. H+ reacts with the scale to dissolve the scale and keep the electrode surface clean.

[0038] Anode reaction formulas: H2O→OH-+H+; OH--e-→·OH; 2·OH+H2O→O3+4H++4e-;

[0039] Cathode reaction: 2H2O + 2e- → H2↑ + 2OH-.

[0040] Working principle of the ozone module: An external power supply provides power through the connection of two electrode plates, forming a closed circuit. Two BDD electrode plates sandwich a proton exchange membrane, forming a series electrode structure with uniform current distribution. At the anode, water molecule dissociation, hydroxyl radical formation, and ozone generation occur; at the cathode, water molecule reduction to hydrogen gas occurs. The proton exchange membrane only allows H+ to pass through, maintaining charge balance between the electrodes. Water molecules adsorb and dissociate on the BDD electrode surface, generating OH- and H+. OH- loses electrons to form hydroxyl radicals (·OH). ·OH reacts with water molecules to generate ozone. The ozone is released into the water flow through the channels between the electrodes and the electrode plates, where it is broken down and dissolved at the semi-circular ozone channel. The specific reaction formula is as follows:

[0041] Water molecules adsorb and dissociate: H2O → OH- + H+;

[0042] Hydroxyl radical formation: OH--e-→·OH;

[0043] Ozone formation: 2·OH + H2O → O3 + 4H+ + 4e-.

[0044] In this embodiment, the main body 1 is a cylindrical structure. The main body 1 is symmetrically divided into a first part 110 and a second part 120 with a semi-circular cross section, with the ozone module as the center. The first part 110 and the second part 120 can be assembled to form a complete main body 1 structure, which facilitates disassembly and assembly as well as the installation and maintenance of internal components. The symmetrical structure makes the water flow distribution uniform and avoids leakage caused by excessive pressure on one side.

[0045] In this embodiment, the first part 110 is provided with a plurality of pins 111 on the surface for connecting with the second part 120, and the second part 120 is provided with a plurality of pin holes 121 on the surface for connecting with the first part 110, which correspond one-to-one with the positions of the pins 111; the pins 111 of the first part 110 are inserted into the pin holes 121 of the second part 120 to ensure that the two parts are precisely aligned and to prevent water leakage caused by assembly misalignment.

[0046] In this embodiment, a fixing sleeve 3 is provided on the outer side of the main body 1 near both ends. The fixing sleeve 3 is fitted on both ends of the main body 1 to enhance the structural strength and resist the expansion or deformation caused by water flow pressure through external mechanical constraints.

[0047] In this embodiment, an annular limiting block 130 is provided on the main body 1 between the two fixed sleeves 3. The limiting block 130 is integrally formed with the main body 1, and the two fixed sleeves 3 respectively abut against the two ends of the limiting block 130. The integrally formed limiting block 130 provides a mechanical stop, restricts the position of the fixed sleeves 3, ensures that they accurately abut against the two ends, ensures that the fixed sleeves are evenly stressed, and improves the structural stability.

[0048] In this embodiment, the ozone channels 140 all have a semi-circular cross-section, and the diameter of the ozone channels 140 is larger than the width of the second channel 231. Both ends of the main body 1 have funnel-shaped through holes 160 corresponding to the ozone channels 140, with the smaller diameter end of each through hole 160 communicating with the corresponding ozone channel 140. The water flow channels 150 all have an arc-shaped cross-section. The semi-circular ozone channels 140 reduce bubble aggregation and improve dissolution efficiency, while the arc-shaped water flow channels 150 utilize curvature to increase turbulence, promoting mixing of water and ozone in the outlet pipe. The special cross-sectional design optimizes fluid dynamics, resulting in more thorough gas-water mixing. The diameter of the semi-circular ozone channels 140 is slightly larger than the width of the first channel 221 and the second channel 231, and the axis of the ozone channels 140 is perpendicular to the long side of the first channel 221. This design optimizes the fluid flow state within the grooves, increases fluid shear force, and facilitates the breakup and uniform dissolution of ozone in the water.

[0049] This application presents an experimental description of a diversion-type ozone-water mixing structure: the overall dimensions are Φ40mm×80mm, the operating voltage is 12V, and the current is 4A. When water flows through the module at a rate of 1L / min, the ozone concentration at the outlet is detected to be 1.2ppm. The calculated energy consumption is 40W / g O3, which is far lower than the energy consumption of existing corona discharge and partial electrolysis modules. Moreover, the ozone concentration is stable, meeting the needs of various water treatment scenarios.

[0050] In long-term use tests, after the module worked continuously for 5000 hours with regular electrode reversal descaling, there was no significant performance degradation and no obvious scale deposition on the electrode surface, verifying the effectiveness of the electrode reversal descaling function and the module's long lifespan advantage.

[0051] This application's technical solution involves a main body with an inlet and outlet pipe connected at both ends. An ozone module for generating ozone is housed inside the main body. Multiple parallel ozone channels are arranged on both sides of the ozone module, all communicating with it. Water flow channels are also arranged on both sides of the ozone module, parallel to the ozone channels but not communicating with the ozone module. The ends of the ozone channels and the ends of the water flow channels are connected to the inlet and outlet pipes, respectively. Water flows in from the inlet pipe and splits into two paths: one part enters the outlet pipe through the water flow channel, and the other part enters the ozone channel. The ozone module electrolyzes the water to generate ozone, which is then injected into the ozone channel, thus creating an ozone-containing environment. Water enters the outlet pipe through the ozone channel, and the ozone water passing through the ozone channel mixes rapidly with the water passing through the water flow channel as it enters the outlet pipe. Multiple ozone and water flow channels divert the water entering the main body. The parallel arrangement of multiple ozone channels disperses the water flow and increases the contact area with the ozone module, thereby increasing the contact between ozone gas and water and improving the mixing efficiency. Furthermore, by first diverting the water and then recombining it, the water flow speed is changed, ensuring sufficient contact between ozone gas and water, thus improving the uniformity of mixing. This design allows water to flow through the main body, generating ozone gas during the water flow process, enabling the flowing water to mix rapidly with the ozone gas, effectively improving the ozone water production efficiency. The split-type water flow design allows ozone water and non-ozone water to mix at the outlet, and the concentration deviation of ozone in the water can be controlled within ±5%, which significantly improves the uniformity and solubility of dissolution. Compared with the existing electrolysis module, the solubility is greatly improved. The overall structure is set as a flow-through type, with water flowing continuously through the main body. Ozone is generated and mixed in real time during the flow process, eliminating the need for a water storage container and enabling instant use. It is suitable for various flowing water scenarios such as faucets and pipes, thus broadening the application range.

Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
