Description

Technical Field

[0001] The utility model relates to the technical field of ozone electrolysis equipment, in particular to an electrolysis device and an electrolytic ozone generator. Background Art

[0002] Electrolysis is commonly used to produce various chemicals, and one of its applications is the production of ozone. Ozone is recognized as the most broad-spectrum and highly effective bactericide in the world. When ozone reaches a certain concentration, it can quickly kill bacteria in water and air. More importantly, ozone is reduced to oxygen after sterilization, so it is a green and environmentally friendly disinfectant. At the same time, existing technologies have applied electrolysis to produce ozone water, and ozone water is used for many fields such as medical care disinfection, household hygiene cleaning and disinfection, planting and breeding industry disinfection, and sewage treatment.

[0003] At present, in the method of preparing ozone by low-pressure electrolysis of water, an ion exchange membrane and anode and cathode catalyst membranes are mainly used to form a membrane electrode assembly, and the membrane electrode assembly is used to electrolyze water to generate ozone.

[0004] However, the design of the small-sized electrolysis generating device on the market fails to meet the production requirements, the ozone concentration generated is low, and it is not conducive to taking away the ozone generated by electrolysis and the heat dissipation of the electrode sheet, thereby greatly limiting the scope of use of ozone. For example: Patent document CN107177861B discloses an ozone generator nozzle, including a cavity, an electrode sheet and a diaphragm arranged inside the cavity. Each cavity is provided with a positive electrode electrolysis chamber, and a negative electrode electrolysis chamber is provided on both sides of the positive electrode electrolysis chamber, and two cathodes, two LCD terminals, two PEM diaphragms, two diamond sheets and partitions are provided inside the electrolysis chamber. In patent document CN107177861B, the electrode sheet and the PEM diaphragm are too closely attached, and the gap is small, making it difficult for the ozone water generated by electrolysis to flow, so the heat generated by electrolysis cannot be taken away, and the heat dissipation performance is poor. At the same time, due to the low fluidity of ozone water, the concentration of ozone water generated per unit area cannot be increased, resulting in a low ozone concentration.

[0005] Another example: Patent document CN112981440A discloses an ozone generator, including a main body shell and a mounting block; an electrolysis chamber is provided on the main body shell, and a water inlet hole, a water outlet hole and a plug hole communicating with the electrolysis chamber are penetrated through the main body shell; an electrode unit and a conductive unit are provided on the mounting block, the mounting block is detachably plugged and fixed to the plug hole, and the electrode unit extends into the electrolysis chamber, and the fluid can flow into the electrolysis chamber through the water inlet hole, and flow to the water outlet hole after passing through the electrode unit for electrolysis; one end of the conductive unit is electrically connected to the electrode unit, and the other end extends out of the electrolysis chamber through the plug hole. In patent document CN112981440A, a water inlet hole and a water outlet hole connected to the electrolysis chamber are provided through the main body shell, and the fluid can flow into the electrolysis chamber through the water inlet hole, and flow to the water outlet hole after passing through the electrode unit for electrolysis. At this time, the path through which the fluid flows is shorter, resulting in a shorter time for flowing through the electrolysis chamber, less ozone dissolution, and thus a lower output ozone concentration. In addition, due to the shorter contact time with the electrolysis chamber, less heat is absorbed.

[0006] Another example: Patent document CN109321938A also discloses an ozone generator, including an anode fluid chamber, an anode frame plate, a membrane electrode assembly, and a cathode frame plate. The anode fluid chamber and the anode frame plate are arranged on the anode side of the membrane electrode assembly, and the cathode frame plate is arranged on the cathode side of the membrane electrode assembly. The anode frame plate is electrically connected to the anode side of the membrane electrode assembly, and the cathode frame plate is electrically connected to the cathode side of the membrane electrode assembly. The anode fluid chamber has a fluid outlet channel opening upward and a fluid inlet channel opening downward, and the cathode frame plate has a vent. In patent document CN109321938A, the anode fluid chamber has a fluid outlet channel opening upward and a fluid inlet channel opening downward, and the fluid flows in from the inlet channel, flows through the anode fluid chamber, and flows out from the outlet channel. Since the time for the fluid to flow through the anode fluid chamber is short, there is a small amount of ozone dissolved, resulting in a low output ozone concentration. Utility Model Content

[0046] Ozone is an allotrope of oxygen. It is a light blue gas with a special smell. Ozone is a strong oxidant. Because of its strong oxidizing ability, it has a strong bactericidal and disinfecting effect. The main ways to prepare ozone are corona method, electrolysis method, ultraviolet method, nuclear radiation method, plasma method, etc. The ozone generation technologies that have been put into use by food, hospitals and pharmaceutical companies mainly include corona discharge method and electrolysis method. At present, water electrolysis is mainly used to produce ozone water in civilian consumer products. In the method of preparing ozone by low-pressure electrolysis of water, an ion exchange membrane and anode and cathode catalyst membranes are mainly used to form a membrane electrode assembly, and the membrane electrode assembly is used to electrolyze water to produce ozone. However, the design of the small-sized electrolysis generating device on the market fails to meet the production requirements, the ozone concentration produced is low, and it is not conducive to taking away the ozone generated by electrolysis and the heat dissipation of the electrode sheet, which greatly limits the scope of use of ozone.

[0047] In view of this, the utility model proposes an electrolysis device 100, which divides the electrolysis chamber into two by using a partition to increase the flow path of the water flow, thereby increasing the amount of ozone dissolved, and also allowing the heat generated in the electrolysis device 100 to be taken away through the electrolyte.

[0048] like Figures 1 to 4 The electrolysis device 100 includes a shell 1, an electrolysis module and a partition 4.

[0049] The shell 1 is open and has a receiving cavity. The specific structure and shape of the shell 1 are not limited and can be square or rectangular.

[0050] The electrolytic module is disposed in the housing 1 , and at least one side of the electrolytic module is spaced apart from the housing 1 to form a flow channel therebetween, so that the electrolyte can flow in the flow channel.

[0051] The spacer 4 is arranged in the flow channel to separate the flow channel into a first flow channel 21 and a second flow channel 22 distributed up and down, the first flow channel 21 and the second flow channel 22 extend along the circumferential side of the electrolytic module, and have two ends in their respective extension directions, the first flow channel 21 and the second flow channel 22 are interconnected at one end, thereby dividing the electrolytic chamber into two, thereby increasing the flow path of the electrolyte, the spacer 4 can be set as a partition, and there is no restriction on the specific structure and shape of the partition, which can be set separately or integrally formed with the electrolytic module or integrally formed with the shell 1.

[0052] The housing 1 is also provided with a liquid inlet 11 and a liquid outlet 12 spaced apart from each other. The liquid inlet 11 is connected to the other end of the first flow channel 21 , and the liquid outlet 12 is connected to the other end of the second flow channel 22 .

[0053] In the technical solution of the present utility model, at least one side of the electrolysis module is spaced apart from the shell 1 to form a flow channel therebetween, so that the electrolyte can flow in the flow channel. In addition, the spacer 4 divides the flow channel into the first flow channel 21 and the second flow channel 22 which are connected up and down, thereby increasing the path for the water to flow through, thereby increasing the amount of ozone dissolved, and also allowing the heat generated in the electrolysis device 100 to be taken away by the electrolyte. In addition, the shell 1 is also provided with a liquid inlet 11 and a liquid outlet 12 which are spaced apart up and down, the liquid inlet 11 being connected to the other end of the first flow channel 21, and the liquid outlet 12 being connected to the other end of the second flow channel 22, so that the electrolyte can flow normally between the first flow channel 21 and the second flow channel 22. Therefore, the technical solution of the present utility model can realize the division of the electrolysis chamber into two, increase the path for the water to flow through, and solve the problems of low ozone concentration and poor heat dissipation of the electrolysis device 100 in the prior art.

[0054] In order to further increase the flow path of the electrolyte, the outer periphery of the electrolytic module and the inner periphery of the shell 1 are spaced apart so that two flow channels are formed between the electrolytic module and the shell 1, each of the flow channels is semi-circular, and each of the flow channels is provided with the spacer 4 so that each of the flow channels is separated to form the first flow channel 21 and the second flow channel 22. By arranging the outer periphery of the electrolytic module and the inner periphery of the shell 1 to be spaced apart to form two flow channels, and at the same time separating the first flow channel 21 and the second flow channel 22 which are connected up and down by the spacer 4, the flow path of the electrolyte is further increased, thereby being able to further improve the ozone concentration and the heat dissipation capacity.

[0055] In order to increase the concentration of ozone, in this embodiment, as Figure 3 As shown, the electrolysis device 100 further includes a bubble fragmentation unit 26 disposed in the second flow channel 22, and the bubble fragmentation unit 26 is used to split the bubbles generated by electrolysis into bubbles of smaller size. When the bubbles generated by electrolysis flow in the second flow channel 22 along with the electrolyte, they can be split into bubbles of smaller size by the bubble fragmentation unit 26. Compared with large bubbles, the total contact area of ​​the split small bubbles becomes larger, thereby increasing the concentration of ozone in water.

[0056] In this embodiment, there is no limitation on the arrangement and quantity of the bubble fragmentation unit 26. The bubble fragmentation unit 26 may be arranged separately or integrally formed with the electrolysis module. Figure 4 As shown, the bubble fragmentation unit 26 is provided separately, and a mounting groove 231 for mounting the bubble fragmentation unit 26 is provided at corresponding positions of the electrolysis module and the partition 4 .

[0057] In order to further break up the bubbles and increase the concentration of ozone, in this embodiment, the bubble breaking unit 26 includes a first filter 261 and a second filter 262, the first filter 261 is provided with a first filter hole, the second filter is provided with a second filter hole, the second filter 262 is located between the first filter 261 and the liquid outlet 12, and the aperture of the second filter hole is smaller than the aperture of the first filter hole, and these filter holes can allow the bubbles generated by the electrolysis unit 24 to pass through. When the bubbles generated by electrolysis pass through the first filter 261, the bubbles will be cut by the first filter hole and become smaller bubbles, and when these bubbles pass through the second filter 262, they will be cut by the second filter hole and become smaller bubbles, thereby improving the dissolution rate of ozone.

[0058] In this embodiment, if Figure 2 and Figure 4 As shown, the housing 1 is also provided with a reflux port 13, and the reflux port 13 is connected to the second flow channel 22; the electrolysis device 100 also includes a reflux device arranged outside the housing 1 and connected to the reflux port 13 and the liquid inlet 11. When the electrolyte flows in the flow channel, a part of the electrolyte will pass through the first flow channel 21 and the second flow channel 22, and then flow out from the liquid outlet 12, and another part of the electrolyte will be discharged into the reflux device through the reflux port 13. At this time, the ozone water with a certain concentration will be sucked into the electrolysis device 100 through the reflux device to react and increase the concentration of ozone, thereby performing multiple cycles, and the ozone concentration of the electrolyte discharged from the liquid outlet 12 will be higher. At the same time, the heat dissipation performance of the device can also be increased by reflux.

[0059] Specifically, the reflux port 13 is disposed at one end of the second flow channel 22 that is in communication with the first flow channel 21. Such a configuration is conducive to the reflux of the electrolyte and further increases the concentration of ozone.

[0060] In this embodiment, if Figure 3 As shown, the electrolysis module includes a main body 23, a support frame 232 and an electrolysis unit 24. The main body 23 is provided with a mounting groove 231 that is arranged to penetrate from top to bottom. The support frame 232 is arranged at the bottom of the main body 23, so that a receiving space 232a is formed between the lower end of the main body 23 and the bottom of the shell 1. The lower end of the electrolysis unit 24 passes through the mounting groove 231 and extends into the receiving space 232a. The upper end of the electrolysis unit 24 is connected to a power source. The lower end of the electrolysis module is set as a support structure in order to accommodate the electrolysis unit 24, so that the electrolysis unit 24 can contact with the electrolyte as much as possible, so that the electrolysis reaction can occur better and more ozone can be generated. The number of the supports is not limited here. In this embodiment, the number of the supports is four.

[0061] Furthermore, if Figure 1 As shown, the electrolytic unit 24 includes a first electrode sheet 241, a second electrode sheet 242, and a separator 243 disposed between the first electrode sheet 241 and the second electrode sheet 242. The separator 243 between the first electrode sheet 241 and the second electrode sheet 242 is an ion exchange membrane. There are a number of through holes in the middle of the electrolytic sheet, and the ion exchange membrane acts as an insulating sheet to prevent the two electrolytic sheets from being directly connected. At this time, when the electrolytic sheets are connected to positive and negative voltages respectively, the surrounding electrolyte can be decomposed to produce ozone.

[0062] Usually, the electrolytic unit 24 also includes a conductive unit 25 for conducting electricity to the electrode sheet. The conductive unit 25 includes a titanium pole piece 251 and a metal spring 252, wherein there are two titanium pole pieces 251, which are respectively attached to the two electrolytic sheets to supply power to the electrolytic sheets. The pins on the titanium pole piece 251 will pass through the openings on the electrolytic module mounting slot 231 of the upper shell and contact the metal spring 252. The metal spring 252 will be stuck in the slot structure in the mounting slot 231 of the metal spring 252. When the metal spring 252 is connected to an external power source, the metal spring 252 first conducts the current to the titanium pole piece 251. After the titanium pole piece 251 is powered on, the current is then conducted to the electrode sheet, so that the electrode sheet can be connected to the current, thereby decomposing the surrounding electrolyte into ozone gas. Here, the material of the metal spring 252 is copper metal.

[0063] Since a gap is likely to be generated when the electrolytic module is directly placed in the shell 1, thereby affecting the electrical performance, after the electrolytic module and the shell 1 are installed, it is necessary to apply potting glue 3 for curing. At this time, the pins of the titanium pole piece 251 and a part of the metal spring 252 are sealed in the potting glue, which can not only effectively solve the problem that the titanium pole piece 251 cannot be soldered and is easily oxidized, but also improve the use scenario of the module.

[0064] In this embodiment, if Figure 2 As shown, in order to fix the electrolytic module, the bottom of the shell 1 is provided with a plurality of limiting ribs 15 around the electrolytic module. When the entire electrolytic module is installed on the shell 1, the limiting ribs 15 surround the bracket of the electrolytic module.

[0065] Furthermore, if Figure 2As shown, the plurality of limiting convex ribs 15 form an opening corresponding to the first flow channel 21, and the inner side wall of the housing 1 is provided with a flow guiding protrusion 14 corresponding to the opening, and the flow guiding protrusion 14 is arranged in a direction away from the liquid inlet 11 and gradually approaches the opening. When the electrolyte flows in the first flow channel 21, the flow guiding protrusion 14 can guide the electrolyte to the electrolytic unit 24, so that the electrolyte flowing in can more effectively undergo an electrolytic reaction. The structure and number of the flow guiding protrusion 14 are not limited, and can be triangular or cylindrical.

[0066] The utility model further proposes an electrolytic ozone generator, including the electrolytic device 100. The electrolytic device 100 specifically refers to the above embodiments. Since the electrolytic ozone generator adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0067] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
