Description

Technical Field

[0001] This invention relates to the field of electrolytic functional water technology, specifically to a continuous preparation equipment for ionized sterilization and insecticidal water. Background Technology

[0002] With the rapid development of green and organic agriculture in my country, the problems caused by the long-term and excessive use of traditional chemical pesticides, such as excessive pesticide residues, soil pollution, increased pest resistance, and ecological damage, have become increasingly prominent, seriously restricting the improvement of agricultural product quality and sustainable agricultural development. Electrolyzed functional water, due to its significant advantages such as broad-spectrum and highly effective sterilization and insecticidal effects, no chemical residues, rapid decomposition, and environmental friendliness, is gradually becoming an important technical means to replace chemical pesticides for agricultural pest and disease control. It is also widely used in sterilization and disinfection operations in medical, food processing, and public environmental fields.

[0003] Currently, most mainstream water electrolysis equipment on the market adopts an integrated cylindrical electrolytic cell structure. Electrolysis is achieved by arranging multiple sets of flat electrodes in parallel inside the cell, along with a simple bottom aeration device to achieve gas-liquid mixing. While this type of equipment has a simple structure, it suffers from several insurmountable defects in practical use. For example, Chinese utility model patent CN212954439U discloses a device for producing slightly acidic electrolyzed water. This device achieves continuous electrolysis production by setting up a primary electrolytic cell and a secondary electrolytic cell, but it has the following significant shortcomings: Firstly, the electrolytic cell has a straight-through flow channel, which results in a short residence time of the material in the electrolysis area and uneven contact with the electrode surface, leading to insufficient electrolysis reaction. This results in a low content of effective bactericidal and insecticidal components in the finished product, making it difficult to achieve the ideal control effect. Secondly, the electrode plates are arranged in a fixed parallel manner, and the material always flows through the electrode surface in a single direction. This easily leads to local polarization on the electrode, causing scaling and corrosion on the electrode surface. This not only shortens the service life of the electrode, but also results in large fluctuations in the physical and chemical properties of the finished product and poor storage stability. Third, the gas-liquid mixing method uses bottom aerators for direct aeration, which produces large and unevenly distributed bubbles, resulting in a small gas-liquid contact area and poor aeration-enhanced oxidation effect. Fourth, the filter components adopt a fixed installation structure, which makes it impossible to perform online backwashing maintenance. The equipment must be stopped for disassembly and cleaning after running for a period of time, which seriously affects the continuous operation capability and production efficiency of the equipment. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the present invention provides an ionization-type sterilization and insecticidal water continuous preparation device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a continuous preparation device for ionized sterilization and insecticidal water, comprising a main body, a movable side plate on one side of the main body, a reaction processing tank fixedly located at the rear of the main body, and a conveying pump located at the front of the main body; the reaction processing tank contains several ionization reaction tanks, and a gas-liquid separation tank is fixedly located at the bottom of the reaction processing tank, with the bottoms of the several ionization reaction tanks communicating with the interior of the gas-liquid separation tank; the ionization reaction tank contains several upper reaction racks and lower reaction racks, which are inclined inside the ionization reaction tank; the several upper reaction racks and lower reaction racks are alternately distributed inside the ionization reaction tank, and adjacent upper reaction racks and lower reaction racks are interconnected; a guide pipe is also provided above one side of the ionization reaction tank, and one end of the guide pipe is connected to the interior of the uppermost upper reaction rack.

[0006] Furthermore, the reaction outlet of the reaction processing tank is connected to the feed end of the conveying pump via a conduit, and the discharge end of the conveying pump is connected to a conveying pipe, which is hung on the front of the main body of the equipment; a feed interface is also provided on the upper back of the main body of the equipment, and one end of the feed interface is connected to the interior of the reaction processing tank.

[0007] Furthermore, porous anode plates and porous cathode plates are fixedly installed on both sides inside the upper and lower reaction frames, and several baffles are also fixedly installed inside the upper and lower reaction frames, with the baffles arranged alternately in the upper and lower positions.

[0008] Furthermore, the porous anode plate inside the upper reaction frame is located on the left side, and the porous cathode plate is located on the right side, while the porous anode plate inside the lower reaction frame is located on the right side, and the porous cathode plate is located on the left side. When the material flows between the upper and lower reaction frames, an S-shaped flow is formed between the upper and lower reaction frames.

[0009] Furthermore, a feeding filter chamber is provided on the left side inside the reaction processing box, and a filter processing frame is provided inside the feeding filter chamber. The upper part of the filter processing frame is connected to one end of the feeding interface. Several filter tanks are vertically arranged inside the filter processing frame, and several filter ports that cooperate with the filter tanks are provided at the top and bottom of the filter processing frame.

[0010] Furthermore, a backwashing interface is fixedly provided on the lower back of the main body of the device, and one end of the backwashing interface is connected to the lower part of the feeding filter chamber.

[0011] Furthermore, a feeding pump is provided in the middle of the reaction processing tank, and the feed end of the feeding pump is connected to the lower part of the feeding filter chamber; a material distribution rack is also fixedly provided in the lower part of the reaction processing tank, and the discharge end of the feeding pump is connected to the interior of the material distribution rack.

[0012] Furthermore, several mixing sections are fixedly installed inside the reaction processing box and on top of the material distribution rack, and the top of each mixing section is connected to one end of the material guide pipe.

[0013] Furthermore, the mixing section includes a contraction section, a throat section, and a diffusion section. The bottom end of the contraction section is fixedly connected to the top of the material distribution frame. The top of the contraction section is fixedly provided with a throat section, and the surface of the throat section is provided with several air inlets. The top end of the throat section is fixedly provided with a diffusion section, and the top end of the diffusion section is connected to one end of the guide pipe.

[0014] Furthermore, the interior of the reaction processing chamber is fixedly equipped with an air supply frame, and the interior of the air supply frame is connected to the interior of the air inlets on the surface of several throat sections.

[0015] The beneficial effects achieved by the present invention using the above structure are as follows: By adopting a pretreatment structure with multi-stage filter tanks in parallel, the raw water can be continuously filtered and softened in multiple stages, effectively removing suspended impurities, colloidal substances, and calcium and magnesium ions from the raw water. This prevents scaling on the electrode surface during subsequent electrolysis from the source. At the same time, the backwashing interface can backwash the filter components during normal operation of the equipment, allowing for cleaning and maintenance of the filter tanks without disassembling any parts of the equipment. This ensures that the equipment can operate stably and continuously for a long time, improving production efficiency per unit time.

[0016] By utilizing the negative pressure generated by the change in fluid velocity, gas is automatically drawn in, and the strong shearing action of the high-speed fluid breaks the drawn-in gas into micron-sized tiny bubbles. This achieves efficient and thorough mixing of the gas and liquid phases without the need for additional power equipment. The bubbles are evenly distributed and have a long residence time in the water, which can significantly improve the effect of the aeration-enhanced oxidation process and promote the generation of a large number of active bactericidal and insecticidal components such as hydroxyl radicals and hypochlorous acid during electrolysis.

[0017] By employing an alternating inclined upper and lower reaction rack structure in the electrolysis reaction zone, an overall S-shaped material flow path is formed. At the same time, each reaction rack is divided into internal S-shaped flow channels by staggered baffles. The double S-shaped flow channel structure significantly extends the residence time of the material in the electrolysis zone, enabling the material to have sufficient and continuous contact with the electrode surface, ensuring that the electrolysis reaction can proceed completely.

[0018] By arranging the anode and cathode plates inside the upper and lower reaction racks in a reverse manner, the material can alternately contact the electrode surfaces of different polarities when flowing between adjacent reaction racks. This effectively avoids the localized polarization phenomenon caused by the material always contacting the same polarity electrode. This not only significantly extends the service life of the electrodes, but also makes the electrolysis reaction more uniform and stable throughout the entire electrolysis area. The physicochemical indicators of the finished product, such as pH value, redox potential, and available chlorine content, fluctuate within a smaller range, and the storage stability is qualitatively improved.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0023] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes an ionization-type sterilization and insecticidal water continuous preparation device.

[0024] Example 1 Please see Figures 1 to 9 As shown, an ionization sterilization and insecticidal water continuous preparation device includes a device body 1, a movable side plate 2 on one side of the device body 1, and a number of heat dissipation holes are provided inside the movable side plate 2 and on one side of the device body 1.

[0025] A reaction processing tank 5 is fixedly installed on the rear side inside the main body 1, and a conveying pump 6 is also installed on the front side inside the main body 1. The reaction outlet of the reaction processing tank 5 is connected to the inlet end of the conveying pump 6 through a conduit, and the outlet end of the conveying pump 6 is connected to a conveying pipe, which is hung on the front of the main body 1. A feeding interface 3 is also provided on the upper back of the main body 1, and one end of the feeding interface 3 is connected to the interior of the reaction processing tank 5.

[0026] In the continuous preparation of sterilization and insecticidal water, the raw materials are fed into the reaction treatment tank 5 through the feed interface 3. After the raw materials are filtered, softened and modified inside the reaction treatment tank 5, a membraneless electrolytic cell is used with titanium-based ruthenium-iridium porous mesh electrodes and a gas-enhanced oxidation process for constant temperature electrolysis. Finally, the liquid in the sterilization and insecticidal water is sent out through the transfer pump 6 via a gas-liquid separation device.

[0027] Specifically, such as Figure 8 and Figure 9As shown, the reaction processing box 5 is equipped with several ionization reaction boxes 14 inside, and a gas-liquid separation box 15 is fixedly installed at the bottom inside the reaction processing box 5. The bottom of the several ionization reaction boxes 14 is connected to the inside of the gas-liquid separation box 15. The ionization reaction box 14 is equipped with several upper reaction racks 22 and lower reaction racks 23 inside, and the upper reaction racks 22 and lower reaction racks 23 are inclined inside the ionization reaction box 14. The several upper reaction racks 22 and lower reaction racks 23 are alternately distributed inside the ionization reaction box 14, and adjacent upper reaction racks 22 and lower reaction racks 23 are connected to each other. A feed pipe 21 is also provided above one side of the ionization reaction box 14, and one end of the feed pipe 21 is connected to the inside of the uppermost upper reaction rack 22.

[0028] Furthermore, porous anode plates 24 and porous cathode plates 25 are fixedly installed on both sides inside the upper reaction frame 22 and the lower reaction frame 23, respectively. Several baffles 26 are also fixedly installed inside the upper reaction frame 22 and the lower reaction frame 23, and the baffles 26 are arranged alternately. The baffles 26 divide the interior of the upper reaction frame 22 and the lower reaction frame 23 into S-shaped flow channels, thereby extending the reaction time of the material inside the upper reaction frame 22 and the lower reaction frame 23.

[0029] The porous anode plate 24 inside the upper reaction frame 22 is located on the left, and the porous cathode plate 25 is located on the right. The porous anode plate 24 inside the lower reaction frame 23 is located on the right, and the porous cathode plate 25 is located on the left. When the material flows between the upper reaction frame 22 and the lower reaction frame 23, an S-shaped flow is formed between the upper reaction frame 22 and the lower reaction frame 23. The material flows sequentially over the surfaces of the porous anode plate 24, the porous cathode plate 25, and the porous anode plate 24 and the porous cathode plate 25. The bottom of the lower reaction frame 23 is connected to the interior of the gas-liquid separation box 15 to perform gas-liquid separation treatment on the sterilization and insecticidal water after the ionization reaction.

[0030] The ionization reaction chamber 14 is equipped with several upper reaction frames 22 and lower reaction frames 23 that are alternately inclined and interconnected, and each reaction frame contains a porous anode plate 24, a porous cathode plate 25, and baffles 26 arranged vertically and vertically. The working principle is as follows: the material enters the uppermost reaction frame 22 through the feed pipe 21, flows along the inclined reaction frame under gravity, and sequentially passes through the alternately distributed upper and lower reaction frames 22 and 23 to form an overall S-shaped flow path. Simultaneously, the baffles 26 inside each reaction frame divide the interior into S-shaped channels, further extending the residence time of the material within a single reaction frame. The porous anode plates 24 and porous cathode plates 25 inside the upper and lower reaction frames 22 and 23 are arranged in a left-right reverse configuration, allowing the material to alternately contact the porous electrode surfaces of different polarities as it flows between adjacent reaction frames.

[0031] The dual S-shaped flow channel structure significantly extends the contact reaction time between the material and the electrode, improving the fullness of the electrolysis reaction. The porous mesh electrode increases the reaction contact area, and combined with the aeration-enhanced oxidation process, it can generate more active oxidizing substances. The alternating reverse arrangement of the anode and cathode plates avoids the local polarization phenomenon caused by the material always contacting the same polarity electrode during the flow process, making the electrolysis reaction more uniform and stable, and ultimately significantly improving the preparation efficiency and sterilization and insecticidal effect of the disinfectant water.

[0032] After the material enters the ionization reaction chamber 14 through the feed pipe 21, it forms a diaphragm-free electrolysis structure with the porous anode plate 24 and porous cathode plate 25 inside the upper reaction frame 22 and the lower reaction frame 23. The electrode is a titanium-based ruthenium-iridium porous mesh electrode. The constant temperature electrolysis operation is carried out in conjunction with the aeration-enhanced oxidation process. During the operation, the various physicochemical indicators of the water are precisely controlled. This equipment can produce two finished products: acidic electrolyzed water and alkaline electrolyzed water. The pH value of the acidic electrolyzed water stock solution is controlled between 1.5 and 2.0, preferably between 1.5 and 1.9; the oxidation-reduction potential is controlled between 900 mV and 1200 mV, preferably between 1185 mV and 1200 mV; the chlorine concentration in the stock solution is between 80 mg / L and 150 mg / L, preferably between 100 mg / L and 150 mg / L; and the sodium mass fraction does not exceed 0.01%. The pH value of the alkaline electrolyzed water stock solution is controlled between 12.5 and 13.5, preferably between 13.1 and 13.5; the oxidation-reduction potential is controlled between -900 mV and -1200 mV, preferably between -1160 mV and -1200 mV; and the potassium mass fraction in the stock solution is not less than 2.0%. After electrolysis, the water is sent to the gas-liquid separator 15 to complete gas-liquid separation, and then subjected to nitrogen protection for settling and fine filtration to finally obtain the finished product, ionized water.

[0033] The electrolyzed water prepared by this process has a high effective chlorine content, broad-spectrum sterilization and fast speed, with a kill rate of no less than 99.99% for common pathogens. At the same time, it can effectively improve the defects of traditional electrolyzed functional water, such as poor stability and easy scaling of electrodes. The finished product can be stored at room temperature for more than 30 days and has the characteristics of low corrosion, no residue and green environmental protection.

[0034] Example 2 like Figure 4 and Figure 5 As shown, a feeding filter chamber 8 is provided on the left side inside the reaction processing chamber 5, and a filter processing frame 7 is provided inside the feeding filter chamber 8. The upper part of the filter processing frame 7 is connected to one end of the feeding interface 3. Several filter tanks 9 are vertically arranged inside the filter processing frame 7. Several filter ports 10 that cooperate with the filter tanks 9 are provided at the top and bottom of the filter processing frame 7. A backwashing interface 4 is also fixedly provided on the lower back of the main body 1, and one end of the backwashing interface 4 is connected to the lower part of the feeding filter chamber 8.

[0035] After the reactants are fed into the filter processing rack 7 through the feed port 3, the reactants are filtered and softened by several filter tanks 9. The material after being filtered by several filter tanks 9 is fed into the lower part of the feed filter chamber 8 through the filter port 10 to complete the pretreatment of the reactants.

[0036] like Figures 4-7 As shown, a feeding pump 11 is provided in the middle of the reaction processing tank 5, and the feed end of the feeding pump 11 is connected to the lower part of the feeding filter chamber 8; a material distribution rack 12 is also fixedly provided in the lower part of the reaction processing tank 5, and the discharge end of the feeding pump 11 is connected to the interior of the material distribution rack 12; a number of mixing parts 13 are fixedly provided in the reaction processing tank 5 and at the top of the material distribution rack 12, and the top of each mixing part 13 is connected to one end of the guide pipe 21.

[0037] Furthermore, the mixing section 13 includes a contraction section 16, a throat section 17, and a diffusion section 18. The bottom end of the contraction section 16 is fixedly connected to the top of the material distribution frame 12. The top of the contraction section 16 is fixedly provided with the throat section 17, and the surface of the throat section 17 is provided with a plurality of air inlets 19. The top end of the throat section 17 is fixedly provided with the diffusion section 18, and the top end of the diffusion section 18 is connected to one end of the guide pipe 21. The interior of the reaction processing box 5 is fixedly provided with an air supply frame 20, and the interior of the air supply frame 20 is respectively connected to the interior of the air inlets 19 on the surface of the plurality of throat sections 17.

[0038] It should be noted that the pre-treated material is fed into the interior of the distribution rack 12 by the feeding pump 11. The distribution rack 12 then feeds the material into the interior of several contraction sections 16. When the material flows through the interior of the throat section 17, negative pressure is generated through several air inlets 19 on the surface of the throat section 17. In conjunction with the air feeding rack 20, nitrogen gas is drawn into the interior of the throat section 17 and sheared and broken into tiny bubbles, achieving preliminary gas-liquid mixing. Finally, the material is fed into the interior of the electrolysis reaction chamber through the guide pipe 21.

[0039] The raw materials are fed into the top of the filter treatment rack 7 through the feed port 3, and flow from top to bottom through multiple vertically arranged filter tanks 9 to complete the pre-treatment of filtration and softening. The pre-treated material enters the lower part of the feeding filter chamber 8 through the filter port 10. The backwash port 4 can reverse the flow of the flushing medium from the lower part of the feeding filter chamber 8 to perform online backwashing maintenance on the filter tanks 9. The pre-treated material is transported to the inside of the distribution rack 12 by the feed pump 11. It is evenly distributed to the contraction section 16 of each mixing section 13 by the distribution rack 12. The flow rate of the material gradually increases in the contraction section 16. When it enters the throat section 17, a negative pressure is generated. Nitrogen gas is drawn in from the inside of the air supply rack 20 through multiple air inlets 19 on the surface of the throat section 17. Under the shearing action of the high-speed fluid, the nitrogen gas is broken into tiny bubbles, realizing the initial and sufficient mixing of the gas and liquid phases. After the mixed material is decelerated and stabilized by the diffusion section 18, it is sent into the electrolysis reaction chamber through the guide pipe 21.

[0040] The filter processing rack 7, with multiple filter tanks connected in parallel, enables continuous filtration and softening of raw materials. The backwashing port 4 allows for cleaning and maintenance of the filter components without disassembling the equipment, ensuring continuous operation. The mixing section 13, based on the Venturi principle, achieves efficient gas intake and microbubble generation without additional power equipment, resulting in good gas-liquid mixing and low energy consumption. The distribution rack 12 ensures uniform feeding of multiple mixing sections 13, providing a stable gas-liquid mixed raw material base for subsequent aeration-enhanced oxidation electrolysis processes, thus improving the stability and consistency of the overall preparation process.

[0041] This equipment uses municipal tap water as the basic raw material for preparing sterilizing and insecticidal ionized water. The raw material enters the filter treatment rack 7 inside the feeding filter chamber 8 through the feed inlet 3. Multi-stage filtration and softening modification are completed by the filter tank 9, achieving pretreatment of the raw water. After pretreatment, food-grade sodium chloride is added to the water to prepare a low-concentration electrolyte solution, which is then transported by the feed pump 11 to the distribution rack 12. After mixing with nitrogen gas in the mixing section 13, it is sent to the subsequent electrolysis process. This equipment can adjust the type of electrolyte according to the application scenario to prepare two types of functional electrolyzed water: one is acidic electrolyzed water, using potassium chloride or sodium chloride as the electrolyte preparation material; the other is alkaline electrolyzed water, using potassium carbonate as the electrolyte preparation material. The two types of electrolyzed water are suitable for different applications such as sterilization and insecticidal treatment.

[0042] Example 3 This embodiment describes the application method and dilution formula of electrolyzed ionized water prepared by the above-mentioned equipment in the field of medicinal herb cultivation for sterilization and insecticidal purposes.

[0043] The acidic and alkaline electrolyzed water produced by the equipment can be diluted with water according to the corresponding ratio before use. This can completely replace chemical pesticides, avoid pesticide residues in medicinal materials, and improve the quality of medicinal materials.

[0044] When using acidic electrolyzed water for sterilization, dilute the acidic electrolyzed water to clean water at a volume ratio of 1:3 to 1:6, and spray the diluted liquid evenly onto the leaves of medicinal herbs or the surface of the planting soil. When using alkaline electrolyzed water for routine sterilization, dilute it to clean water at a volume ratio of 1:12 to 1:24 before spraying it onto the leaves or soil surface. When carrying out insect control operations during the egg stage of medicinal herbs, use alkaline electrolyzed water, diluting it to clean water at a volume ratio of 1:13 to 1:24, and spray it onto the leaves of medicinal herbs and the surrounding soil. This can effectively kill insect eggs and control pest breeding.

[0045] The electrolyzed ionized water produced by this equipment is suitable for planting various common medicinal herbs such as Adenophora stricta, Codonopsis pilosula, Lithospermum erythrorhizon, Saposhnikovia divaricata, and Glycyrrhiza uralensis. Taking Adenophora stricta as an example, for fungal diseases such as root rot that are common in Adenophora stricta, regular spraying with diluted acidic or alkaline electrolyzed water can effectively control the disease without the need for chemical agents, thus ensuring the safety of medicinal herb planting.

[0046] The working principle of this application is as follows: Step 1: The raw materials are fed into the feeding filter chamber 8 on the left side of the reaction processing tank 5 through the feed interface 3 on the back of the main body 1, and flow into the top of the filter processing frame 7. They flow from top to bottom through several vertically arranged filter tanks 9 inside the filter processing frame 7, completing the multi-stage filtration and soft water modification pretreatment of the raw water. The pretreated material is collected at the bottom of the filter processing frame 7 through the filter port 10 and then collected below the feeding filter chamber 8.

[0047] Step 2: Food-grade electrolyte is added to the pretreated material to prepare a low-concentration electrolyte aqueous solution. The solution is then drawn out by the feed pump 11 in the middle of the reaction processing tank 5 and transported to the distribution rack 12 at the bottom of the reaction processing tank 5. The distribution rack 12 evenly distributes the material into the shrinkage section 16 of several mixing sections 13 fixed at its top.

[0048] Step 3: As the material flows in the contraction section 16 of the mixing section 13, the channel gradually narrows and the flow rate continues to increase. When it enters the throat section 17, a negative pressure effect is generated. Nitrogen gas is drawn in from the gas feeder 20 inside the reaction processing box 5 through several air inlets 19 on the surface of the throat section 17. The high-speed flowing material shears and breaks the drawn-in nitrogen gas into tiny bubbles, achieving preliminary and thorough mixing of the gas and liquid phases. After the mixed material is decelerated and stabilized in the diffusion section 18, it is transported to the inside of the ionization reaction box 14 through the feed pipe 21.

[0049] Step 4: The gas-liquid mixture enters the uppermost reaction rack 22 inside the ionization reaction chamber 14 through the feed pipe 21. Under the action of gravity, it flows downward along the inclined upper reaction rack 22 and flows through several alternating and interconnected upper reaction racks 22 and lower reaction racks 23 in sequence, forming an overall S-shaped flow path.

[0050] Step 5: When the material flows inside each upper reaction rack 22 and lower reaction rack 23, it is blocked by several baffles 26 arranged vertically inside, and flows along the S-shaped flow channel formed by the baffles 26, further prolonging the residence time of the material inside the reaction rack.

[0051] Step Six: The porous anode plate 24 and porous cathode plate 25 inside the upper reaction rack 22 are arranged in a left-right reverse manner with the porous anode plate 24 and porous cathode plate 25 inside the lower reaction rack 23. When the material flows between adjacent reaction racks, it can alternately contact the surface of titanium-based ruthenium-iridium porous mesh electrodes of different polarities. Combined with the diaphragm-free constant temperature electrolysis process and the aeration-enhanced oxidation process, the ionization reaction is completed to generate sterilized and insect-repellent ionized water.

[0052] Step 7: After the ionization reaction is completed, the material flows into the gas-liquid separator 15 from the bottom of the lower reaction rack 23 for gas-liquid separation. The separated gas is discharged from the equipment, and the separated liquid sterilization and insect removal water is collected at the bottom of the gas-liquid separator 15.

[0053] Step 8: The sterilizing and insecticidal water after gas-liquid separation is transported through a conduit to the feed end of the conveying pump 6 on the front side of the main body of the equipment. After being pressurized by the conveying pump 6, it is sent out of the main body of the equipment through the discharge end connected to and hung on the front of the main body of the equipment, thus completing the continuous preparation process of the sterilizing and insecticidal water.

[0054] This solution for a continuous ionization-based sterilization and insecticidal water preparation system primarily addresses the common problems in traditional ionization-based sterilization and insecticidal water preparation equipment, including incomplete electrolysis, short and uneven contact time between materials and electrodes leading to localized polarization and electrode scaling, unstable product performance, poor gas-liquid mixing affecting the aeration-enhanced oxidation process, inconvenient maintenance of filter components preventing continuous production, and low effective component content, limited sterilization and insecticidal effects, and poor storage stability in the prepared electrolyzed water. The innovation of this solution lies in the inclusion of a feeding system with a filter rack 7 and a backwashing interface 4 inside the reaction tank 5. The filter chamber 8 utilizes multiple vertically arranged filter tanks 9 to achieve continuous multi-stage filtration and softening pretreatment of raw water. At the same time, the backwashing interface 4 enables online backwashing maintenance of the filter tanks 9, allowing cleaning without disassembling the equipment and ensuring long-term stable and continuous operation. By setting up a Venturi mixing section 13 composed of a contraction section 16, a throat section 17, and a diffusion section 18, and in conjunction with the air supply frame 20, nitrogen gas is automatically drawn in and sheared and broken into microbubbles by the negative pressure effect generated by the fluid flowing through the throat section 17. Efficient and thorough mixing of the gas and liquid phases can be achieved without additional power equipment, providing a stable gas-liquid mixed raw material for the subsequent aeration-enhanced oxidation electrolysis process.

[0055] The inventiveness of this application lies in the use of alternating, inclined, and interconnected upper and lower reaction racks 22 and 23 within the ionization reaction chamber 14, forming an overall S-shaped material flow path. Simultaneously, each upper and lower reaction rack 22 and 23 is separated by staggered baffles 26, forming internal S-shaped flow channels. This double S-shaped flow channel structure significantly extends the residence time of the material in the electrolysis zone. Furthermore, the porous anode plates 24 and porous cathode plates 25 within the upper and lower reaction racks 22 and 23 are arranged in a left-right reverse configuration, allowing the material to flow smoothly in adjacent... When the material flows between the reaction racks, it can alternately contact the surfaces of titanium-based ruthenium-iridium porous mesh electrodes of different polarities, effectively avoiding local polarization and electrode scaling problems caused by the material always contacting the same polarity electrode. This significantly improves the uniformity and completeness of the electrolysis reaction, enhances the generation of active bactericidal and insecticidal components, and ultimately produces bactericidal and insecticidal ionized water with high content of effective components, good bactericidal and insecticidal effects, and a storage time of more than 30 days at room temperature. Overall, it realizes the efficient, stable, and continuous preparation of bactericidal and insecticidal water, greatly improving the production efficiency of the equipment and the performance of the products.
