DETAILED DESCRIPTION

[0037] The technical solutions of the present application will be described clearly and completely below in conjunction with the drawings. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application. In the description of the present application, it should be noted that the orientations or positional relationships indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0038] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0039] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0040] As shown in Figure 1 The application provides an activated water preparation device, which comprises a water tank 1, a reactor 5 and a second electrode 4. The water tank 1 contains a water solution 8 to be treated. The reactor comprises a first electrode 52 and a containing part 51. After the first electrode 52 and the second electrode 4 are electrified, electrons form a closed loop circuit from the first electrode 52 to the air to the containing part 51 to the water and finally to the second electrode 4. The device can only normally operate when there is air in the inner wall of the containing part 51. Therefore, after electrification, the water tank 1 must be aerated and drained before electrification. During the discharge process, high pressure will open oxygen molecules, water molecules and nitrogen molecules in the air and form a series of complex physical and chemical reactions to finally generate plasma active substances. Further, the reactor 5 extends into the water solution 8 to be treated, and the second electrode 4 is placed below the liquid level of the water solution 8 to be treated. The reactor 5 and the second electrode 4 circulate and transport gas by a pump body. The pump body transports gas to the reactor 5, ionizes the gas to generate air plasma, and transmits the air plasma to the water solution 8 to be treated. Ionization occurs at the gas-liquid interface.

[0041] Specifically, the water tank 1 is used to contain the water solution 8 to be treated. The shape and size of the water tank 1 can be set according to the actual needs, and the water tank 1 can be made of insulating materials. In the preferred embodiment of the application, the water tank 1 can be made of plastic materials. The water solution 8 to be treated is specifically a water solution. After the air plasma enters the water solution, H+, NO2- and NO3- are generated.

[0042] Further, the second electrode 4 wrapped by an insulating medium can also be arranged at the bottom of the water tank 1. The second electrode 4 described herein is specifically a ground electrode, and the reactor 5 can be a high-voltage electrode. In the specific use process, the products under different discharge modes are different. The arc mode mainly generates hydrogen peroxide active particles, the glow mode mainly generates nitric acid and nitrous acid, and the mixed mode of the two can generate hydrogen peroxide and nitric acid and nitrous acid active particles. The arc hole 512 provided by the application is used to generate a glow arc mixed mode, which can generate more mixed particles to improve the sterilization efficiency.

[0043] Further, since the inner wall of the water tank 1 is made of insulating materials, the inner wall of the water tank 1 will appear intermittent starlight during the discharge process. The main reason is that part of the water vapor or water is adsorbed to the inner wall of the water tank 1 under the action of bubbles. Since the inner wall of the water tank 1 is made of insulating materials, the water film potential on the inner wall and the water potential in the water tank 1 form a potential difference. When a certain local potential is reached, starlight creeping phenomenon occurs, which causes part of the injected energy to be lost, thereby affecting the activated water treatment efficiency. Therefore, the inner wall of the water tank 1 is coated with a conductive coating, which forces the water film adsorbed on the inner wall of the water tank 1 to form an equipotential state with the water solution, which can effectively solve the inner wall creeping and thereby improve the preparation efficiency.

[0044] Further, as shown in Figure 2 and Figure 3 , the water solution surface of the water to be treated in the water tank 1 is arranged at the middle position of the water tank 1, the middle part of the reactor 5 is arranged in the water solution 8 to be treated, and the second electrode 4 is arranged below the reactor 5 and penetrates the middle and lower part of the water tank 1. As a preferred embodiment, the second electrode 4 is a ground electrode, and the reactor 5 comprises a first electrode 52 which is a high-voltage electrode. The first electrode 52 and the second electrode 4 are connected to a power supply to ionize the air flowing between the first electrode 52 and the second electrode 4 to generate plasma. The plasma is mixed with the water solution 8 to be treated in the water tank 1 to generate peroxynitrite, hydrogen peroxide, nitric acid, nitrous acid and other substances with anti-cancer and sterilization functions, thereby preparing plasma-activated water.

[0045] Further, the gas between the first electrode 52 and the second electrode 4 can be circulated reciprocally through pipelines inside and outside the water tank 1. After the air is fully reacted with the water solution, a gas-liquid mixture with high temperature and high humidity is formed. The gas-liquid mixture is circulated through the second electrode 4 to cool and dry the gas-liquid mixture with high temperature and high humidity, thereby forming low-temperature and dry gas which is circulated into the first electrode 52 to react, thereby effectively improving the sterilization efficiency of the plasma-activated water.

[0046] As shown in Figure 10 , the second electrode 4 is arranged in the water solution 8 to be treated in the water tank 1. As a preferred embodiment, the second electrode 4 is horizontally arranged at the bottom of the water tank 1. Generally, the water tank 1 is a square tank, and the second electrode 4 is arranged at the position close to the bottom of the water tank 1, and the two ends of the second electrode 4 penetrate the opposite two side walls of the water tank 1. Of course, it can be understood that the second electrode 4 can also be arranged obliquely at the bottom of the water tank 1. In addition to being connected to a power supply, the second electrode 4 can also extend the flow path of the gas and uniformly distribute the potential in the solution.

[0047] As a preferred embodiment, the second electrode 4 is a horizontal serpentine pipeline. In order to extend the flow path of the gas, the second electrode 4 can condense, dry and cool the gas flowing in, so that the gas flowing through the second electrode 4 is dry and low-temperature gas. Of course, it can be understood that the shape of the second electrode 4 can be a U-shaped pipeline, an S-shaped pipeline or a plurality of pipeline bends connected, as long as it can extend the flow path of the gas-liquid mixture.

[0048] Further, the outer wall of the second electrode 4 is coated with a layer of polytetrafluoroethylene dielectric layer, which can avoid short circuit caused by direct contact between the high-voltage electrode and the ground electrode, and also reduce the creepage phenomenon at the connection between the electrode and the water tank 1. Of course, it can be understood that the dielectric layer coated on the outer wall of the second electrode 4 can also be other dielectric layers as long as it can withstand high temperature and high pressure. The coated dielectric layer is not specifically limited, and other dielectric layers that can withstand high temperature and high pressure are also within the protection scope of the embodiments of the present application.

[0049] Further, the resistance of the water solution 8 to be treated gradually decreases during the discharge process, but the resistance fluctuation is relatively large and extremely uneven, so that the potential uniformity in the solution can be improved under the action of the second electrode 4. On the other hand, since the discharge device needs to be circulated multiple times during operation to improve the plasma dissolution rate, the high humidity of the circulating gas during the circulation process causes too many water droplets on the glass tube of the reactor 5, which causes creepage or even sparking phenomenon, thereby reducing the energy loss and processing efficiency of the discharge process. The circulating gas flow path flows through the inside of the second electrode 4, which can play a condensing and cooling role, so that the humidity of the gas flowing out of the second electrode 4 can be effectively reduced, thereby improving the processing efficiency of the gas in the high-voltage electrode glass tube. The outer wall of the ground electrode is coated with a layer of polytetrafluoroethylene dielectric layer, which can avoid short circuit caused by direct contact between the high-voltage electrode and the ground electrode, and also reduce the creepage phenomenon at the connection between the electrode and the water tank 1.

[0050] As shown in Figure 1 and Figure 2 , the circulation path of the gas is that the gas flows from the first electrode 52 to the water tank 1, then flows from the water tank 1 to the second electrode 4, and then flows back to the first electrode 52, thereby forming a gas loop.

[0051] Specifically, the side wall of the water tank 1 is provided with a first gas outlet 11, and the second electrode 4 is provided with a first gas inlet 41, and the first gas outlet 11 and the first gas inlet 41 are connected by a pipeline. The second electrode 4 is provided with a second gas outlet 42, and the reactor 5 is provided with an air inlet pipe 521, and the second gas outlet 42 is connected with the air inlet of the pump body, and the air inlet pipe 521 is connected with the air outlet of the pump body. The second electrode 4 includes at least two loops connected with each other, and the gas-liquid mixture passes through the at least two loops for condensation and drying, so as to prolong the flow path of the gas-liquid mixture in the second electrode 4.

[0052] As a preferred embodiment, the pump body can be a circulating pump, which is provided with an air inlet and an air outlet, so that the gas can be circulated between the first electrode 52, the water tank 1, the second electrode 4 and the circulating pump.

[0053] Further, as shown in Figure 1 and Figure 2As shown, the water tank 1 is provided with a cover 2, the cover 2 is provided with a fixing frame 3, and the reactor 5 is arranged on the fixing frame 3 so that the reactor 5 is partially accommodated in the water solution 8 to be treated. The reactor 5 includes a plurality of reactors 5 which are arranged at equal intervals on the fixing frame 3, and the plurality of reactors 5 are connected by a connecting plate 6. An accommodation space 21 is formed between the reactor 5 and the cover 2, and the accommodation space 21 is filled with a sealing and insulating material.

[0054] Further, as a preferred embodiment, the sealing and insulating material is epoxy resin. Of course, it can be understood that other sealing and insulating materials are also within the scope of the embodiments protected by the present application.

[0055] Further, the fixing frame 3 is provided with a flow distribution plate 7, one side of the flow distribution plate 7 is provided with a second gas inlet 72 connected with the gas outlet of the pump body, and the other side of the flow distribution plate 7 is provided with a plurality of third gas inlets 73 connected with the gas inlet pipe 521, and the pump body delivers the gas to the plurality of reactors 5 through the flow distribution plate 7.

[0056] Specifically, as shown in the figure, Figure 2 the flow distribution plate 7 is arranged on one side wall of the cover 2, the middle of the flow distribution plate 7 is provided with an accommodation groove 71 which mainly accommodates the gas output by the pump body. One side of the accommodation groove 71 is provided with the second gas inlet 72 connected with the pump body, and the number of the second gas inlet 72 is one. The other side of the accommodation groove 71 is provided with at least two third gas inlets 73, of course, it can be understood that the number of the third gas inlets 73 can be three or more, and each third gas inlet 73 corresponds to the first gas inlet 41 arranged on each reactor 5, so that the gas flowing into each first gas inlet 41 through the second gas inlet 72 can be distributed through the accommodation groove 71.

[0057] As shown in the figure, Figures 4 to 9 the reactor 5 includes an accommodation part 51 with an opening, the accommodation part 51 is provided with a first electrode 52, the first electrode 52 and the accommodation part 51 form a gas flow channel, the accommodation part 51 is placed in the water solution 8 to be treated, and the opening of the accommodation part 51 is provided with a sealing member 53 to improve the air tightness between the accommodation part 51 and the first electrode 52.

[0058] Further, the accommodation part 51 includes a tubular structure with an opening, and the first electrode 52 is a columnar structure which penetrates through the sealing member 53 and extends into the accommodation part 51, so that the sealing member 53 and the accommodation part 51 are clamped and fixed.

[0059] Of course, as a preferred embodiment, the sealing member 53 and the accommodation part 51 can be made of glass material, and the sealing member 53 or the accommodation part 51 can be made of glass material or ceramic material respectively, as long as the insulation function can be achieved.

[0060] Further, the sealing member 53 comprises a connecting surface 531, and the opening inner wall of the accommodating portion 51 is provided with a third contact surface 515, the connecting surface 531 of the sealing member 53 and the third contact surface 515 are in contact, so that the sealing member 53 and the accommodating portion 51 are sealingly connected. The third contact surface 515 and / or the connecting surface 531 is provided as a glass rough surface, and the third contact surface 515 and / or the connecting surface 531 is coated with a sodium hydroxide solution. In order to improve the air tightness between the first electrode 52 and the accommodating portion 51, the connecting mode of frosted glass is adopted for connection, and the first electrode 52 and the sealing member 53 can be made into one body through a high-temperature processing process before assembly, wherein the connecting surface 531 in the sealing member 53 is a rough surface. The upper end tapered surface of the accommodating portion 51 is made of a frosted glass tube, wherein the second contact surface 514 and the third contact surface 515 are rough surfaces. When assembling, the connecting surface 531 and the third contact surface 515 are matched, and sodium hydroxide solution is added to the connecting surface 531 and the third contact surface 515 at the same time to cause a chemical reaction to form a protective film, thereby ensuring the air tightness of the connecting surface 531. The same method is used to connect the accommodating portion 51 and the cover 2 of the water tank 1. The first contact surface 511 is frosted glass, which is processed into the cover 2 of the water tank 1 in an embedded manner. When installing, the first contact surface 511 and the second contact surface 514 in the glass tube are matched and a protective film is formed by a chemical reaction under the action of the sodium hydroxide solution, thereby achieving the sealing effect.

[0061] Further, the first electrode 52 comprises a first body 523 and a second body 524, which are connected in sequence so that the second body 524 is accommodated in the accommodating portion 51. The first body 523 has a hollow structure, and the second body 524 has a solid structure. The material of the first electrode 52 needs to have the characteristics of high temperature and high pressure resistance and corrosion resistance.

[0062] Further, a plurality of through holes are provided on the outer wall of the first body 523, so that the gas in the first body 523 flows out through the through holes to the hollow region formed between the accommodating portion 51 and the second body 524. The side wall of the first body 523 is communicated with the gas inlet pipe 521, so that the gas flows into the first body 523 through the gas inlet pipe 521, and then flows out through the through holes.

[0063] Further, the gas inlet pipe 521 and the side wall of the first body 523 are provided with an included angle, and the value of the included angle is in the range of 0° to 90°, so that the water droplets in the gas inlet pipe 521 automatically flow back to the inner wall of the accommodating portion 51. The purpose is to make the water droplets in the pipeline automatically flow back to the inner wall of the glass tube during operation. The gas is introduced from the gas inlet into the gas inlet pipe 521, and then uniformly discharged from the through holes after passing through the hollow region at the upper end of the first electrode 52, so that the gas flow distribution of the inner wall of the glass tube is uniform. During the discharge process, the electrode device requires high air tightness, and the assembled parts must maintain good sealing.

[0064] As a preferred embodiment, the outer wall of the second body 524 is coated with a dielectric layer 54, which is a polytetrafluoroethylene coating, to increase the arc voltage and stabilize the discharge.

[0065] Further, the bottom of the first body 523 is provided with an arc hole 512, which is located below the liquid level of the water solution 8 to be treated. The bottom of the accommodating portion 51 is provided with a plurality of first gas outlet holes 513. As a preferred embodiment, the diameter of the arc hole 512 ranges from 0.05 mm to 0.5 mm. According to the theory of plasma-activated water, the concentration of active particles generated in the glow arc mixed mode is higher, which is more conducive to improving the preparation efficiency of activated water, and therefore the arc hole 512 is added in the middle of the glass tube.

[0066] The principle of arc mode discharge is that a high-voltage electrode forms a loop with a low potential when the local field strength of the high-voltage electrode is too high during the discharge process, which can produce a violent arc. The purpose of the arc hole 512 in the middle of the glass tube is to artificially increase the loop of the high-voltage electrode and the water solution, that is, the high-voltage electrode forms a path with the water solution 8 to be treated through the arc hole 512 during the discharge process. When a certain field strength is reached, a very obvious arc will be formed between the high-voltage electrode and the water solution 8 to be treated, at which time a large amount of hydrogen peroxide active particles will be generated. In addition to the arc generated around the arc hole 512 in the middle, the high-voltage electrode will generate a glow mode, so that the concentration of active particles is relatively high in the mixed mode, thereby improving the treatment efficiency of activated water. Traditional discharge devices generally use aeration stones for aeration, but the installation of aeration stones and discharge devices is complex, and different expansion coefficients of the two different materials will cause air and water leakage during operation, which will cause the creeping phenomenon. The embodiment provided in the present application integrates the aeration device and the glass tube into one body, effectively reducing a series of problems generated during the installation process, and through experimental verification, the feasibility of improving the gas-liquid mass transfer efficiency by the arc hole 512 aeration is verified, and finally the diameter of the micro-pore is selected to be 0.1 mm-1 mm.

[0067] The present application proposes to use the glass tube arc hole 512 method for aeration, which effectively simplifies the installation difficulty, and can realize the glow arc mixed mode, greatly improving the preparation efficiency of activated water. The discharge electrode is designed by using a segmented processing method, the gas inlet pipe 521 is integrated with the electrode, which reduces the processing difficulty and effectively improves the discharge stability of the system. The ground glass tube structure is used for sealing, which ensures the air tightness during the operation of the system, thereby effectively reducing the energy loss and improving the treatment efficiency of activated water.

[0068] The reactor 5 provided by the application improves the air tightness of the first electrode 52 and the accommodating portion 51 by arranging the sealing member 53 on the accommodating portion 51. The arc hole 512 arranged on the side wall of the accommodating portion 51 improves the transmission efficiency of the active particles. The segmented media layer coated on the first electrode 52 makes the discharge process generate a glow arc mixed mode, effectively improving the discharge treatment efficiency.

[0069] The activated water preparation device provided by the application horizontally places the second electrode 4 at the bottom of the water tank 1, and coats a polytetrafluoroethylene coating on the outer wall of the second electrode 4, effectively solving the creeping phenomenon of the second electrode 4, and the inner wall of the second electrode 4 can cool the circulating gas, thereby reducing the water droplets on the inner wall of the first electrode 52 and improving the discharge efficiency.
