Description

Technical Field

[0001] This invention belongs to the field of water purification technology, specifically relating to a double-sided water electrolysis device. Background Technology

[0002] Electrolyzed water typically refers to the products generated after electrolyzing water containing salts (such as sodium chloride). The electrolyzed water itself is neutral, but it can be supplemented with other ions or separated through a semi-permeable membrane to produce two types of water: alkaline ionized water and acidic ionized water. Electrolyzed water using sodium chloride as the electrolyte will contain sodium hydroxide, hypochlorous acid, and sodium hypochlorite after electrolysis (if pure water is electrolyzed, only hydroxide ions, hydrogen gas, oxygen gas, and hydrogen ions will be produced).

[0003] Patent application number 201911061246.9 discloses a small-scale water electrolysis device and system. The document also discloses the following information: Electrolyzed water is classified according to its pH value into strongly acidic electrolyzed water (pH 2.3-2.7), strongly alkaline electrolyzed water (pH 11-11.5), weakly acidic electrolyzed water (pH 5-6), electrolyzed sub-water (pH 8-9), and alkaline ionized water (pH 8-10). Strongly acidic electrolyzed water is known for its strong bactericidal power and good safety. Its bactericidal targets are not limited to common bacteria but also have the effect of killing HIV, HBV, and Bacillus spores. It has a wider range of applicability than glutaraldehyde and disinfectant ethanol, and is therefore widely used as a cleaning agent to prevent infection, a disinfectant for medical equipment, and a disinfectant for human skin and mucous membranes.

[0004] Currently, the production of strongly acidic electrolyzed water typically involves injecting a saline solution of less than 0.1% into an electrolytic cell equipped with an anode, a cathode, and a separator between the anode and cathode, followed by electrolysis. The electrolytic cell is the key piece of equipment in this process. Commonly used electrolytic cells are typically twin-cylinder type with plate electrodes. Under low voltage and low current conditions, their electrolysis efficiency is low and cannot meet the requirements for continuous and large-volume supply of electrolyzed water with a specified pH value in short periods, such as when cleaning medical instruments like endoscopes in hospitals.

[0005] However, currently known hypochlorous acid water generators are mainly used in industrial applications, and they are generally complex in structure, large in size, expensive, and have high maintenance costs. In recent years, with the frequent occurrence of infectious diseases, there is a great need in the market for small, inexpensive, reliable, and widely applicable electrolytic water production equipment as a means of preventing infection, to meet the daily needs of households, community healthcare stations, and hospitals.

[0006] Therefore, given the problems of complex structure, troublesome maintenance, and limited applicability of existing water electrolysis preparation devices, a more reasonable technical solution is needed to solve the current technical problems. Summary of the Invention

[0007] The purpose of this invention is to provide a double-sided water electrolysis device to solve the problems of complex structure, troublesome maintenance and limited applicability of existing water electrolysis preparation devices.

[0008] To achieve the above objectives, the present invention provides a double-sided water electrolysis device, comprising an anode frame, a cathode frame, an electrolytic membrane, and a perforated plate. The anode frame is provided with a first cavity to form an anode chamber. The cathode frames are configured in two sets and respectively disposed on both sides of the anode frame. The two ends of the anode frame are respectively provided with a water inlet and a water outlet.

[0009] Electrolytic membranes are sequentially arranged on both sides of the anode frame. The electrolytic membranes are located between the anode frame and the cathode frame. The cathode frame is fixedly connected to the anode frame by fasteners, so that the electrolytic membranes and the upper second cavity of the cathode frame together form a cathode chamber.

[0010] The perforated plates are configured in two pairs, with each pair of perforated plates respectively attached to both sides of the electrolytic membrane, and the perforated plates are sealed to the anode frame and the cathode frame; wherein, the perforated plates are also provided with a plurality of perforations arranged in an array, so that the liquid in the anode chamber can flow to the cathode chamber through the perforations;

[0011] The cathode frame is provided with an electrolyte inlet for introducing electrolyte and an electrolyte outlet for discharging electrolyte; pipe joints are provided at the water inlet, water outlet, electrolyte inlet and electrolyte outlet.

[0012] The anode chamber contains an anode plate, which is electrically connected to the positive terminal of an external power source; the cathode chamber contains a cathode plate, which is electrically connected to the negative terminal of an external power source.

[0013] In one possible design, both the anode frame and the cathode frame are provided with grooves for accommodating annular washers; the annular washers are embedded in the grooves one by one; and the perforated plate presses against the annular washers.

[0014] In one possible design, the groove has a semi-circular cross-section.

[0015] In one possible design, the drain holes are configured as square holes; the drain holes are arranged in a matrix.

[0016] In one possible design, the drain holes are configured as circular holes; the drain holes are arranged circumferentially.

[0017] In one possible design, the pipe fitting is configured as a one-touch pipe fitting.

[0018] The above technical solution allows for the continuous production of electrolyzed water through two cathode chambers. This simplifies the electrolyzer structure while ensuring both efficiency and quality, and effectively guarantees a stable supply and high efficiency of the electrolyzed water. This double-sided electrolysis device can rapidly change the pH value of the electrolyzed water, reaching a maximum of 12, thus achieving effective pH control. By simultaneously electrolyzing water on both sides, the device significantly increases the effective electrolytic area of ​​the electrodes, thereby greatly improving the electrolysis efficiency. Therefore, the optimized structure of the device reduces space requirements while maintaining efficiency and quality.

[0019] The device has a simple structure, is easy to operate, and has good economic efficiency and practicality. It can be better adapted to ordinary family life and can meet the daily needs of residents, community health care stations, and hospitals, thus expanding its application scope from the industrial field to the residential field and broadening the application range of the water electrolysis device.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that while the description of these embodiments is intended to aid in understanding the present invention, it does not constitute a limitation thereof.

[0027] The specific structural and functional details disclosed herein are for illustrative purposes only and are intended to describe exemplary embodiments of the invention. However, the invention may be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0028] In recent years, with the frequent occurrence of infectious diseases, there is a great demand in the market for small, inexpensive, reliable, and widely applicable electrolytic water production equipment as a means of preventing infection, to meet the daily needs of households, community healthcare stations, and hospitals. In response, this disclosure proposes a double-sided electrolytic water device that can output electrolyzed water from two directions. Furthermore, the device can use potassium carbonate or sodium carbonate as the electrolyte, producing an alkaline stock solution after electrolysis. Figures 1 to 4 A specific implementation method is shown.

[0029] See Figures 1 to 4 As shown, the double-sided water electrolysis device includes an anode frame 1, a cathode frame 2, an electrolytic membrane, and a perforated plate 3. The anode frame 1 has a first cavity to form an anode chamber. The cathode frames 2 are arranged in two sets and are respectively located on both sides of the anode frame 1. The two ends of the anode frame 1 are respectively provided with a water inlet 11 and a water outlet 12.

[0030] An electrolytic membrane is sequentially disposed on both sides of the anode frame 1. The electrolytic membrane is located between the anode frame 1 and the cathode frame 2. The cathode frame 2 is fixedly connected to the anode frame 1 by fasteners, so that the electrolytic membrane and the upper second cavity of the cathode frame 2 together form a cathode chamber.

[0031] The perforated plates 3 are configured in two pairs, with each pair of perforated plates 3 respectively attached to both sides of the electrolytic membrane, and the perforated plates 3 are sealed to the anode frame 1 and the cathode frame 2; wherein, the perforated plates 3 are also provided with a plurality of perforations 31 arranged in an array, so that the liquid in the anode chamber can flow to the cathode chamber through the perforations 31.

[0032] The cathode frame 2 is provided with an electrolyte inlet 21 for introducing electrolyte and an electrolyte outlet 22 for discharging electrolyte; pipe joints are provided at the water inlet 11, water outlet 12, electrolyte inlet 21 and electrolyte outlet 22; an anode plate is provided in the anode chamber and is electrically connected to the positive terminal of an external power supply; a cathode plate is provided in the cathode chamber and is electrically connected to the negative terminal of an external power supply.

[0033] The above technical solution allows for the continuous production of electrolyzed water through two cathode chambers. This simplifies the electrolyzer structure while ensuring both efficiency and quality, and effectively guarantees a stable supply and high efficiency of the electrolyzed water. This double-sided electrolysis device can rapidly change the pH value of the electrolyzed water, reaching a maximum of 12, thus achieving effective pH control. By simultaneously electrolyzing water on both sides, the device significantly increases the effective electrolytic area of ​​the electrodes, thereby greatly improving the electrolysis efficiency. Therefore, the optimized structure of the device reduces space requirements while maintaining efficiency and quality.

[0034] The device has a simple structure, is easy to operate, and has good economic efficiency and practicality. It can be better adapted to ordinary family life and can meet the daily needs of residents, community health care stations, and hospitals, thus expanding its application scope from the industrial field to the residential field and broadening the application range of the water electrolysis device.

[0035] In one embodiment provided in this disclosure, both the anode frame 1 and the cathode frame 2 are provided with grooves for accommodating annular washers; the annular washers are correspondingly embedded in the grooves; and the perforated plate 3 presses against the annular washers. This ensures the sealing performance of the device. The annular washers are made of a flexible material resistant to acids and alkalis, such as the plastic rings used in this disclosure.

[0036] In this disclosure, the leakage holes 31 are configured as square holes; the leakage holes 31 are arranged in a matrix. This increases the area of ​​the leakage holes 31 while ensuring the strength of the leakage plate 3, which is beneficial for facilitating rapid liquid flow.

[0037] Specifically, both the anode frame 1 and the cathode frame 2 are square.

[0038] In another embodiment, the drain holes are arranged in a circular pattern to allow for smooth liquid flow and increase the flow cross-section. The anode frame 1 and the cathode frame 2 are circular.

[0039] In other embodiments, the anode frame 1 and the cathode frame 2 may also be in shapes other than square and circular. Those skilled in the art can flexibly configure them according to the application scenario.

[0040] When the cathode frame 2 and the anode frame 1 are arranged in a circular shape, the corresponding electrolytic membrane and the perforated plate 3 are also arranged in a circular shape.

[0041] Furthermore, the groove has a semi-circular cross-section. This not only provides a better sealing effect but also facilitates cleaning and maintenance.

[0042] In this disclosure, the pipe fitting is configured as a single-contact fitting, which can prevent liquid backflow from contaminating the internal electrolysis environment of the cathode and anode chambers.

[0043] Finally, it should be noted that the principle of water electrolysis is common knowledge, and the components mentioned in this application, such as the electrolytic membrane, are also existing technologies, so they will not be described in detail here.

[0044] It should be noted that the present invention is not limited to the optional embodiments described above, and anyone can derive other various forms of products under the guidance of the present invention.
