[0033] Ozone gas is usually mixed with water to generate ozone water before use. The existing ozone generator usually needs to be placed in a container filled with water when in use. The water is electrolyzed to generate ozone gas, and the ozone gas is mixed with water by itself diffusion to form ozone water. However, this method has the phenomenon of uneven mixing, and the flow of ozone water generated at a time is also limited due to the limited volume of the container.

[0034] Therefore, the present application provides an ozone gas-water mixing device.

[0035] In the first embodiment of the present application, referring to Figures 1 to 3 The ozone gas-water mixing device comprises a main body 1, two ends of the main body 1 are used to connect a water inlet pipe and a water outlet pipe, an ozone module for generating ozone is arranged in the inside of the main body 1, a plurality of parallel ozone channels 140 are arranged on both sides of the ozone module in the inside of the main body 1, the cross section of the ozone channel 140 is a U-shaped structure or a semicircular structure, the plurality of ozone channels 140 are communicated with the ozone module, and the two ends of the plurality of ozone channels 140 are connected with the water inlet pipe and the water outlet pipe respectively.

[0036] Specifically, the water flow enters the main body 1 through the water inlet pipe, converges to the ozone module through the ozone channels 140 on both sides, and after the ozone generation is completed in the ozone module, the water carrying ozone flows to the water outlet pipe along the ozone channel 140; when the cross section of the ozone channel 140 is a U-shaped structure, the water flow increases the flow rate and the Reynolds number after passing through the ozone channel 140, forms a turbulent flow, enhances the gas-liquid mass transfer efficiency, and increases the dissolution efficiency of ozone in water by 30%-50%; when the cross section of the ozone channel 140 is a semicircular structure, the water flow also forms a turbulent flow, reduces bubble aggregation, and improves the dissolution efficiency; the plurality of parallel ozone channels 140 disperse the water flow, avoid insufficient mixing caused by too high local flow rate, and further strengthen the gas-liquid contact through the fluid disturbance between the channels, so that the ozone and water are fully mixed, thereby significantly improving the dissolution efficiency of ozone in water.

[0037] In the first 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 cross section of a semicircle with the ozone module as the center, the outer side of the main body 1 is sleeved with a first fixing sleeve 3 and a second fixing sleeve 4 near the two ends respectively, an annular limiting block 130 is arranged on the main body 1 between the first fixing sleeve 3 and the second fixing sleeve 4, the limiting block 130 is integrally formed with the main body 1, and the first fixing sleeve 3 and the second fixing sleeve 4 are respectively located at the two ends of the limiting block 130; the first part 110 and the second part 120 can form a complete main body 1 structure through assembly, which is convenient for installation and maintenance of internal components, the symmetrical structure makes the water flow uniform, avoids leakage caused by excessive pressure on one side, the first fixing sleeve 3 and the second fixing sleeve 4 are sleeved on the two ends of the main body 1, the external mechanical constraint is resisted, the expansion or deformation caused by the water flow pressure is resisted, the integrally formed limiting block 130 provides a mechanical stop, limits the positions of the first fixing sleeve 3 and the second fixing sleeve 4, ensures that the first fixing sleeve 3 and the second fixing sleeve 4 are accurately located at the two ends, ensures that the first fixing sleeve 3 and the second fixing sleeve 4 are uniformly stressed, enhances the structural strength, and improves the structural stability.

[0038] In the first embodiment, the ozone module includes a first electrode sheet 210, a first proton film 212 and a second proton film 213 are tightly arranged on the two sides of the first electrode sheet 210 respectively, a first power supply sheet 214 is tightly arranged on the other side of the first proton film 212, a second electrode sheet 211 is tightly arranged on the other side of the second proton film 213, a second power supply sheet 216 is tightly arranged on the other side of the second electrode sheet 211, and the first electrode sheet 210 and the second electrode sheet 211 are both BDD electrode sheets; an external power supply applies a direct current voltage to the electrode sheets through the power supply sheets, wherein the first electrode sheet 210 serves as a cathode, the second electrode sheet 211 serves as an anode, a proton exchange membrane (PEM) is used to separate the cathode and the anode, water electrolysis is performed on the anode side to generate O3, and protons are reduced to H2 on the cathode side; the proton exchange membrane is a Nafion membrane, the proton exchange membrane selectively conducts H+, the sulfonic acid group of the Nafion membrane fixes a negative charge, attracts H+ migration (σH+≈0.1S / cm), forces electrons to pass through an external circuit, and improves current efficiency; the electrode sheet and the proton exchange membrane are tightly combined to reduce interface resistance and ensure stable electrolysis under high current density.

[0039] In the first embodiment, a plurality of first through-slots 218 are uniformly and linearly arranged on the side surface of the first proton membrane 212 and the second proton membrane 213, a second through-slot 219 is arranged on the side surface of the second electrode sheet 211 corresponding to the first through-slot 218, and a third through-slot 220 is arranged on the side surface of the first power supply sheet 214 and the second power supply sheet 216 corresponding to the first through-slot 218. The first through-slot 218, the second through-slot 219, and the third through-slot 220 are all rectangular structures, and the long sides of the first through-slot 218, the second through-slot 219, and the third through-slot 220 are all perpendicular to the ozone channel 140. The width of the second through-slot 219 is greater than the width of the first through-slot 218, and the width of the third through-slot 220 is greater than the width of the second through-slot 219. The water flow passes through the third through-slot 220, the second through-slot 219, and the first through-slot 218 in sequence, forming a gradient flow rate in the through-slots of different widths, promoting the shear mixing of ozone and water, and strengthening the fluid collision of the rectangular through-slots. The rectangular through-slots are perpendicular to the ozone channel 140, so that the water flow direction and the ozone diffusion direction intersect, enhancing the mass transfer effect.

[0040] Working principle of the ozone module:

[0041] Cathode reaction (hydrogen evolution reaction):

[0042] 2H + +2e - ->H2↑(acidic environment)

[0043] or 2H2O+2e - ->H2↑+2OH - (neutral / alkaline environment)

[0044] This reaction consumes protons (H+), maintaining the ion conduction balance of the proton membrane. The hydrogen gas evolved can be carried out by the water flow, avoiding the accumulation of gas affecting the electrolysis efficiency.

[0045] Anode reaction (second electrode sheet surface):

[0046] H2O->O3+H + +e -

[0047] 2·OH->O3+H2O

[0048] Hydroxyl radicals (·OH) are efficiently generated on the surface of the electrode sheet, and then ozone is synthesized.

[0049] Specifically, to remove scale on the electrode surface, the electrode polarity can be periodically switched, so that the original first electrode sheet temporarily acts as an anode and the second electrode sheet acts as a cathode. H+ reacts with scale to dissolve the scale, keeping the electrode surface clean.

[0050] Reverse polarity scale removal anode oxidation reaction (first electrode sheet as temporary anode):

[0051] CaCO3+2H + ->Ca 2+ +H2O+CO2↑

[0052] Mg(OH)2+2H + ->Mg 2+ +2H2O

[0053] During the reverse polarity, strong acidic micro-environment (pH≈2~3) is generated on the surface of the first electrode, which directly dissolves the calcium carbonate and magnesium hydroxide scale. Meanwhile, the electrochemical oxidation can degrade the organic pollutants (such as microbial membrane).

[0054] Cathodic reaction during reverse polarity scale removal (the second electrode as a temporary cathode):

[0055] 2H2O+2e - ->H2↑+2OH -

[0056] The generated OH-can neutralize the local acidity and avoid long-term corrosion of the electrode.

[0057] The synergy of the proton exchange membrane, normal mode, only allows H+from the anode to the cathode, maintains charge balance; reverse polarity mode, H+reverse migration, accelerate the cathode scale dissolution.

[0058] In the first embodiment, the first fixed sleeve 3 and the second fixed sleeve 4 are structures made of conductive materials, which can be stainless steel, aluminum alloy, copper alloy and other materials that can conduct electricity and have certain strength. The first fixed sleeve 3 and the second fixed sleeve 4 are used to be electrically connected with the external power supply. The first power supply piece 214 is provided with a first connecting part 215 extending out of the main body 1. The second power supply piece 216 is provided with a second connecting part 217 extending out of the main body 1. The first connecting part 215 and the second connecting part 217 are both arc-shaped structures with elasticity. The first connecting part 215 is used to contact the inner side of the first fixed sleeve 3. The second connecting part 217 is used to contact the inner side of the second fixed sleeve 4. The external power supply supplies power to the power supply piece through the first and second fixed sleeves 4. The elastic connecting part deforms during assembly to ensure reliable electrical contact with the inner wall of the fixed sleeve. The elastic contact can compensate for manufacturing tolerances to ensure stable current during equipment vibration or temperature changes. It is suitable for complex environments such as vehicle-mounted or mobile disinfection equipment. The connecting part can be repeatedly disassembled and reused, reducing the maintenance workload during long-term operation.

[0059] Specifically, a first arc-shaped slot 111 is formed on the outer side of the first part 110 of the main body 1 corresponding to the first connecting part 215, and a second arc-shaped slot 121 is formed on the outer side of the second part 120 of the main body 1 corresponding to the second connecting part 217; the first arc-shaped slot 111 is used to accommodate the first connecting part 215, and the second arc-shaped slot 121 is used to accommodate the second connecting part 217, so that the first fixing sleeve 3 and the second fixing sleeve 4 can be tightly fitted when they are sleeved on the outer side of the main body 1.

[0060] In the first embodiment, the cross section of the ozone channel 140 is in a U-shaped structure, and the plurality of ozone channels 140 are divided into a plurality of first flow channels 141 and a plurality of second flow channels 142. The cross sections of the plurality of first flow channels 141 and the plurality of second flow channels 142 are distributed in a radial direction of the main body 1. The cross-sectional area of the first flow channel 141 is greater than that of the second flow channel 142. The cross sections of the first flow channel 141 and the second flow channel 142 are in a circular arc structure away from the side of their own openings. The corners in the first flow channel 141 and the second flow channel 142 are provided with a circular arc transition structure. When the water flows through the first flow channel 141 and the second flow channel 142 with a U-shaped cross section, the water flow velocity increases, the Reynolds number increases, and a turbulent flow is formed, which enhances the gas-liquid mass transfer efficiency and improves the ozone dissolution efficiency in water by 30%-50%. The first flow channel 141 dominates the main flow, and the second flow channel 142 balances the flow velocity to avoid water flow dead zones and ensure the uniformity of the flow field.

[0061] Specifically, in the first embodiment, eight ozone channels 140 in a U-shaped structure are provided, and the first part 110 and the second part 120 of the main body 1 each have four ozone channels 140, including two first flow channels 141 in the middle and two second flow channels 142 on both sides of the first flow channel 141. The four U-shaped ozone channels 140 form a multi-channel shunt, and the water flow velocity is uniformly distributed to avoid short-circuit flow. The right-angle edges of the four U-shaped ozone channels 140 enhance the turbulent flow and improve the ozone dissolution rate (Reynolds number Re≈3000-5000, in the transition turbulent flow region). It is suitable for medium flow (such as household water purifiers and small ozone water machines) and occasions that require stable ozone concentration.

[0062] In the first embodiment, the advantages of the U-shaped ozone channel are:

[0063] Fluid mechanics: The U-shaped cross section provides a symmetrical flow channel, and the turbulent intensity is moderate when the water flows through, which can ensure sufficient contact between ozone and water and avoid excessive pressure drop;

[0064] Bubble breaking efficiency: The right-angle edges of the U-shaped cross section can cut bubbles (similar to the Venturi effect), promote the breaking of large ozone bubbles into small bubbles, and improve the dissolution efficiency;

[0065] Processing and sealing: U-shaped section is easy to achieve high precision by CNC machining.

[0066] In the second embodiment of the present application, referring to Figures 4-7 Compared with the first embodiment, the difference is that the ozone module comprises a third proton film 230, the two sides of the third proton film 230 are respectively tightly arranged with third electrode sheets 231, the third electrode sheets 231 are BDD electrode sheets, the side surfaces of the third electrode sheets 231 are tightly arranged with third power supply sheets 232, the two third power supply sheets 232 are respectively provided with third connecting parts 235 extending out of the main body 1, the third connecting parts 235 are used for connecting an external power supply; wherein the main function of the third proton film 230 is selective permeation, only allowing H+ to pass through, so as to maintain the charge balance between the anode and the cathode; one of the two third power supply sheets 232 is connected with the positive electrode, and the other is connected with the negative electrode, when the third electrode sheet is powered, it will supply power to the corresponding third electrode sheet 231, and generate ozone by electrolysis of water.

[0067] In the second embodiment, a plurality of fourth through grooves 233 are uniformly arranged on the third electrode sheet 231 along a straight line, a fifth through groove 234 is arranged on the third power supply sheet 232 corresponding to the fourth through groove 233, the fourth through groove 233 and the fifth through groove 234 are both rectangular structures, the long sides of the fourth through groove 233 and the fifth through groove 234 are both perpendicular to the ozone channel 140, and the width of the fifth through groove 234 is greater than that of the fourth through groove 233; the water flow passes through the fifth through groove 234 of the third power supply sheet 232 and the fourth through groove 233 of the third electrode sheet 231, and contacts the surface of the third proton film 230, so as to promote the electrolysis reaction; the design of the fourth through groove 233 and the fifth through groove 234 increases the contact area of the water flow with the third electrode sheet 231, optimizes the ion transmission in the electrolysis process, in addition, the uniform distribution of the through grooves disperses the water flow and improves the electrolysis stability; wherein the width size of the fifth through groove 234 is greater than that of the fourth through groove 233, so that a pressure difference is formed when the water flow passes through, the turbulent flow effect is enhanced, the mixing of ozone and water is promoted, and the ozone dissolution rate is improved.

[0068] Specifically, in order to remove the water scale on the surface of the electrode, the polarity of the electrode (positive and negative) can be periodically switched, so that the original cathode becomes anode and the anode becomes cathode, the water scale is dissolved by the reaction of H+ and water scale, and the surface of the electrode is kept clean.

[0069] Anode reaction formula: H2O→OH-+H+; OH-e-→·OH; 2·OH+H2O→O3+4H++4e-;

[0070] Cathode reaction formula: 2H2O+2e-→H2↑+2OH-.

[0071] The working principle of the ozone module is as follows: an external power supply supplies power through the connecting portions of the two power supply sheets to form a closed loop, the two BDD electrode sheets hold the proton membrane to form a series electrode structure, and the current is uniformly distributed. The anode undergoes water molecule dissociation, hydroxyl radical formation and ozone generation reaction, and the cathode undergoes water molecule reduction to generate hydrogen. The proton membrane only allows H+ to pass through, maintaining the charge balance of the two poles. Water molecules are adsorbed and dissociated on the surface of the BDD electrode to generate OH- and H+, OH- loses electrons to form hydroxyl radicals ·OH, ·OH reacts with water molecules to generate ozone, ozone is released into the water flow through the through-slots of the third electrode and the third power supply sheet, and is broken and dissolved at the semicircular ozone passage. The specific reaction formulae are as follows:

[0072] Water molecule adsorption and dissociation: H2O→OH-+H+;

[0073] Formation of hydroxyl radicals: OH-→·OH;

[0074] Ozone generation: 2·OH+H2O→O3+4H++4e-.

[0075] In the second embodiment, the inside of the main body 1 corresponds to the two sides of the ozone module, and is respectively provided with a water flow passage 150. The two water flow passages 150 are respectively located on the first part 110 and the second part 120, and are parallel to the ozone passage 140. The water flow passage 150 is not communicated with the ozone module, and the two ends of the water flow passage 150 are respectively connected with the water inlet pipe and the water outlet pipe. The water flows into the water inlet pipe and is divided into two parts, one part enters the water outlet pipe through the water flow passage 150, and the other part enters the ozone passage 140.
