Description

Technical Field

[0001] This utility model relates to the field of electrolysis equipment technology, and in particular to a reactor for disinfection and oxygenation of aquaculture water for aquaculture. Background Technology

[0002] In high-density aquaculture, the routine application of antibiotics has become a primary technique for controlling bacterial diseases. However, long-term monitoring data shows that this approach not only accelerates the evolutionary selection pressure on drug-resistant strains but also leads to the accumulation of recalcitrant chemical pollutants in the aquaculture ecosystem. In contrast, hydrogen peroxide, as an environmentally friendly oxidant with spontaneous degradation properties, utilizes hydroxyl radicals (hydroxyl radicals) to... - The strong oxidizing effect of OH enables the inactivation of a broad spectrum of pathogens. Its decomposition products are only water and oxygen, which has been proven to not induce drug resistance. It has shown significant technological substitution value in the field of pathogen control.

[0003] Currently, disinfection in aquaculture relies heavily on purchasing hydrogen peroxide solutions. This traditional method of relying on purchased solutions carries inherent safety risks due to the storage and transportation of hazardous chemicals. Furthermore, the limitations of offline solution preparation processes make it difficult to dynamically match disinfectant concentration with aquatic environmental parameters. In addition, the fluid dynamics of open aquaculture waters further contribute to the inability to achieve uniform distribution of the disinfectant to meet the requirements for precise disinfection.

[0004] However, currently available electrolysis production equipment is mainly developed for large-scale industrial applications. Its inherent design flaws include low equipment integration resulting in excessive space occupancy and energy conversion efficiency not optimized for aquaculture applications.

[0005] Therefore, there is an urgent need in this field for a water disinfection and aeration reactor for aquaculture to solve the above problems. Utility Model Content

[0030] 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 of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] The purpose of this invention is to provide a water disinfection and oxygenation reactor for aquaculture, which solves the problems existing in the prior art. It has the advantages of simple structure and small size, thus occupying less space and having high energy conversion efficiency.

[0032] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] like Figure 1 As shown, this embodiment provides a reactor for disinfection and oxygenation of aquaculture water, including an electrolyte container, a detection tank, a reactor body, and an electrolysis power source. The electrolyte container is filled with the electrolyte required for the reaction. The electrolyte is prepared by dissolving sodium sulfate in tap water, i.e., a sodium sulfate solution. The electrolyte container is connected to the inlet of the reactor body via an inlet pipe, and the detection tank is connected to the outlet of the reactor body via an outlet pipe. An ultraviolet spectrophotometer is installed at the detection tank to measure the degree of light absorption, thereby calculating the hydrogen peroxide content. In addition, to ensure smooth flow of the solution in the inlet and outlet pipes, a peristaltic pump is installed on each pipe to provide power for the solution flow. Existing silicone flexible tubing can be used for the inlet and outlet pipes.

[0034] The reactor body contains a first cathode body 3, an anode plate 5, and a second cathode body 7. The first cathode body 3 and the second cathode body 7 are respectively positioned on opposite sides of the anode plate 5. The space between the first cathode body 3 and the anode plate 5 forms the first cathode chamber, and the space between the second cathode body 7 and the anode plate 5 forms the second cathode chamber. Each of the first and second cathode chambers is connected to an inlet and an outlet. The inlet is located at the lower end of the corresponding first or second cathode chamber, and the outlet is located at the upper end. This extends the residence time of the electrolyte in the first and second cathode chambers, resulting in a more complete reaction and improved efficiency. An existing DC power supply is sufficient for electrolysis. The first cathode body 3 and the second cathode body 7 are both electrically connected to the negative terminal of the electrolysis power supply, and the anode plate 5 is electrically connected to the positive terminal of the electrolysis power supply, thereby supplying power to the first cathode body 3, the second cathode body 7, and the anode plate 5.

[0035] In practical use, the electrolyte in the electrolyte container enters the reactor body through the inlet. A peristaltic pump regulates the liquid flow rate, ensuring it fills the entire first and second cathode chambers. The electrolysis power supply is activated, and a certain voltage is input to the first cathode body 3, the second cathode body 7, and the anode plate 5, causing the electrolyte to undergo an electrolytic reaction in the first and second cathode chambers, producing hydrogen peroxide. The resulting solution flows out through the outlet at the top, is tested in a detection tank, and then enters the aquaculture water area for disinfection.

[0036] In this embodiment, the reactor body also includes a first protective plate 1 and a second protective plate 9, such as Figure 1 As shown, the first protective plate 1 is located on the side of the first cathode body 3 away from the anode plate 5, and the second protective plate 9 is located on the side of the second cathode body 7 away from the anode plate 5. That is, the first protective plate 1 and the second protective plate 9 are the two opposite outer walls of the reactor body. Of course, in order to ensure the sealing of the first cathode body 3, the second cathode body 7, and the anode plate 5 and other related components, the first protective plate 1 and the second protective plate 9 can also extend into a rectangular cylindrical structure inward (i.e., on their adjacent sides). When the first protective plate 1 and the second protective plate 9 are fixed together, the rectangular cylindrical structure on the first protective plate 1 and the second protective plate 9 can press the first cathode body 3, the anode plate 5 and the second cathode body 7 located in the middle, so that they can be squeezed firmly against each other, thereby ensuring their sealing.

[0037] In this embodiment, a first perforated plate 2 is provided between the first protective plate 1 and the anode plate 5. The first cathode body 3 is installed on the first perforated plate 2 by internal hexagonal plastic screws. The first perforated plate 2 is provided with a plurality of first vent holes. The first protective plate 1 is provided with a first protective plate vent hole. One side of the first vent hole is connected to the first cathode chamber, and the other side of the first vent hole is connected to the first protective plate vent hole.

[0038] Similarly, a second perforated plate 8 is provided between the second protective plate 9 and the anode plate 5. The second cathode body 7 is installed on the second perforated plate 8 by internal hexagonal plastic screws. The second perforated plate 8 is provided with multiple second vent holes. The second protective plate 9 is provided with second protective plate vent holes. One side of the second vent hole is connected to the second cathode chamber, and the other side of the second vent hole is connected to the second protective plate vent hole.

[0039] Both the vent holes of the first and second protective plates can be connected to an air source, which can be a pump or cylinder connected by a pipeline.

[0040] In practical use, taking one side of the first cathode chamber as an example, when the electrolysis power supply is started, electrolyte will be introduced into the first cathode chamber for electrolysis. During this process, in order to increase the oxygen content of the reaction solution, air or oxygen needs to be introduced into the first cathode chamber. At this time, the gas source can be turned on, so that the air or oxygen at the gas source is delivered to the vent hole of the first protective plate through the pipeline. Then the air or oxygen will pass through the first cathode body 3 and the first porous plate 2 and enter the first cathode chamber (of course, in order to allow the air or oxygen to pass through the first cathode body 3 smoothly, the first cathode body 3 is also provided with multiple cathode vent holes, and the second cathode body 7 is also provided with cathode vent holes), thereby providing oxygen to the reaction solution.

[0041] The oxygenation process in the second cathode chamber is exactly the same as that in the first cathode chamber, so it will not be described again.

[0042] Furthermore, since the first cathode body 3 and the second cathode body 7 are air diffusion cathodes, in addition to providing the oxygen required for the reaction through a gas source, they can also automatically capture the required oxygen from the air after being energized. Figure 1 The first protective plate 1 and the second protective plate 9 are provided with a hollow oxygen-capturing zone in the middle, which is to increase the exposed area of ​​the first cathode body 3 and the second cathode body 7 and capture oxygen to participate in the reaction.

[0043] In this embodiment, a first flow channel baffle 4 is provided between the first cathode body 3 and the anode plate 5; similarly, a second flow channel baffle 6 is provided between the second cathode body 7 and the anode plate 5. It should be noted that both the first flow channel baffle 4 and the second flow channel baffle 6 are provided with serpentine flow channels, with the inlet and outlet being the inlet and outlet ends of the serpentine flow channels, respectively. The advantage of this arrangement is that it lengthens the movement path of the electrolyte in the first and second cathode chambers, thereby increasing its residence time within the reactor body and resulting in a more complete reaction. Furthermore, the inlet is located below the outlet, allowing the liquid to flow from bottom to top, further enhancing the reaction's completeness.

[0044] In this embodiment, a first sealing ring is provided between the first flow channel partition 4 and the anode plate 5 to improve the sealing performance between the first flow channel partition 4 and the anode plate 5. Similarly, a second sealing ring is provided between the second flow channel partition 6 and the anode plate 5 to improve the sealing performance between the second flow channel partition 6 and the anode plate 5.

[0045] In this embodiment, the diameter of both the first vent and the second vent is 0.4 cm, which facilitates the supply of air or oxygen to the first cathode chamber or the second cathode chamber. Both the first porous plate 2 and the second porous plate 8 are made of stainless steel to enhance the strength of the reactor body. Furthermore, the stainless steel material of the first porous plate 2 and the second porous plate 8 allows them to function normally in high-salt or humid environments, demonstrating good corrosion resistance.

[0046] Both the first protective plate 1 and the second protective plate 9 are existing acrylic plates, preferably transparent acrylic plates, so that staff can directly observe the operating conditions of their internal components.

[0047] In this embodiment, the thickness of the first flow channel baffle 4 and the second flow channel baffle 6 is 0.3 cm. The advantage of this setting is that it can shorten the distance between the cathode (i.e., the first cathode body 3 or the second cathode body 7) and the anode (i.e., the anode plate 5), thereby reducing the resistance between the cathode and the anode.

[0048] In this embodiment, the first protective plate 1, the first perforated plate 2, the first cathode body 3, the first flow channel partition 4, the anode plate 5, the second flow channel partition 6, the second cathode body 7, the second perforated plate 8, and the second protective plate 9 are all provided with multiple fixing holes. Specifically, a fixing hole can be provided at the four corners of each component.

[0049] It also includes several double-ended bolts, with each bolt corresponding to a specific fixing hole in terms of both number and position; therefore, four double-ended bolts are provided. Each double-ended bolt passes sequentially through the corresponding fixing holes on the first protective plate 1, the first perforated plate 2, the first cathode body 3, the first flow channel partition 4, the anode plate 5, the second flow channel partition 6, the second cathode body 7, the second perforated plate 8, and the second protective plate 9. A fixing nut is then threaded onto each end of the double-ended bolt. This achieves the fastening effect between the first protective plate 1, the first perforated plate 2, the first cathode body 3, the first flow channel partition 4, the anode plate 5, the second flow channel partition 6, the second cathode body 7, the second perforated plate 8, and the second protective plate 9.

[0050] In this embodiment, both the first cathode body 3 and the second cathode body 7 are provided with cathode conductive through holes, and also include cathode conductive screws, which pass through the two cathode conductive through holes in sequence. Of course, to prevent the cathode conductive screws from contacting the anode plate 5, a corresponding clearance window can be provided on the anode plate 5, allowing the cathode conductive screws to pass through without contacting it. The cathode conductive screws are connected to the negative terminal of the electrolysis power supply via cathode wires, thereby achieving electrical connection between the first cathode body 3 and the second cathode body 7 and the negative terminal of the electrolysis power supply.

[0051] Similarly, the anode plate 5 is provided with an anode conductive through hole, and an anode conductive screw is provided on the anode conductive through hole. The anode conductive screw is connected to the positive terminal of the electrolysis power supply through an anode wire, thereby realizing the electrical connection between the anode plate 5 and the positive terminal of the electrolysis power supply.

[0052] In this embodiment, the first cathode body 3 and the second cathode body 7 are air diffusion cathodes, specifically CB-PTFE air diffusion cathodes. CB-PTFE air diffusion cathodes are special electrodes designed with carbon black (CB) and polytetrafluoroethylene (PTFE) as core materials. Through optimized microporous structure and hydrophobic / hydrophilic balance, they achieve efficient natural oxygen diffusion and electrochemical reactions. The anode plate 5 is a conventional ruthenium-iridium-plated titanium plate. Of course, those skilled in the art can use other structures to replace the first cathode body 3, the second cathode body 7, and the anode plate 5 in this embodiment; it is not limited to this one.

[0053] This embodiment comprises a dual-cathode symmetrical structure consisting of a first cathode body 3, a second cathode body 7, and an anode plate 5. Oxygen (O2) from the air is adsorbed onto active sites on the surface of the cathode catalyst layer (i.e., the first cathode body 3 and the second cathode body 7). After activation by the catalyst, the O2 molecule accepts an electron and a proton (H). + Formation of adsorbed intermediates * OOH; subsequently *OOH further combines with another electron and a proton to finally generate hydrogen peroxide. The anode simultaneously completes the water oxidation production, realizing the co-production of H2O2 and O2.

[0054] This embodiment employs a dual-cathode symmetrical distribution structure (centrally positioned anode), whose innovative geometric arrangement maximizes the effective working area of ​​the anode, thereby simultaneously optimizing hydrogen peroxide yield and energy conversion efficiency under the same energy consumption conditions. Two ultra-thin first flow channel baffles 4 and second flow channel baffles 6 precisely control the anode-cathode distance within the millimeter scale, thus reducing overall internal resistance. This embodiment achieves in-situ hydrogen peroxide generation based on electrochemical synthesis, and its concentration can be precisely controlled in a gradient manner by adjusting core electrochemical parameters such as current density and voltage in real time. The oxygen released simultaneously during hydrogen peroxide generation can be directly dissolved in water; this in-situ oxygenation effect effectively improves the dissolved oxygen level of the aquaculture system. The reactor body adopts a compact structural design, combining modularity and portability. The operation process requires no complex chemical reagent addition or external feeding procedures, avoiding by-product treatment and significantly lowering the technical application threshold. In the field of aquaculture, this embodiment can be adapted to scenarios such as online disinfection of aquaculture water and control of pathogenic microorganisms. Its environmental protection characteristics and operational safety meet the requirements of aquaculture industry standards, and the decomposition products (H2O, O2) do not pose an ecotoxicity risk. The natural replenishment mechanism of dissolved oxygen further enhances the ecological regulation function of the system.
