Technical Field

[0001] This invention relates to the field of air purification technology, and in particular to an electrochemical air purification device. Background Technology

[0002] Currently, the main gaseous pollutants in the air include formaldehyde, benzene compounds, volatile organic compounds, organochlorides, alcohols, ethers, as well as sulfur dioxide and nitrogen oxides. These pollutants not only pollute the environment but also pose serious threats to human health. At the same time, bacteria, viruses, and other microorganisms in the air can also be transmitted through respiratory contact, posing health risks. Therefore, efficient air purification and disinfection are of significant practical importance.

[0003] Current air purification technologies are mainly reactive degradation technologies. Reactive degradation technologies can catalytically decompose volatile organic pollutants into harmless substances, and the catalysts can be used for a long time, thus having greater application prospects. However, the current mainstream reactive degradation technologies include low-temperature plasma technology and catalytic oxidation technology, both of which have problems such as secondary pollution and easy deactivation of catalysts, resulting in short lifespans.

[0004] To address the aforementioned issues, developing an electrochemical air purification device that can continuously supply electrolytes, has stable ion conduction, and high purification efficiency has significant application value. Summary of the Invention

[0005] This invention proposes an electrochemical air purification device, which aims to purify air through electrochemical means, continuously supplying electrolytes, ensuring stable ion conduction, and achieving high purification efficiency.

[0006] To achieve the above objectives, the present invention proposes an electrochemical air purification device comprising: a mounting base, an anode, a cathode, a water distribution component, and a water pump. The anode is disposed within the mounting base; the cathode is disposed opposite to the anode and is also disposed within the mounting base; the water distribution component is disposed between the anode and the cathode; and the water pump is connected to the water distribution component for circulating and transporting water containing electrolyte to the water distribution component. The water distribution component has multiple vertically extending first channels and multiple second channels extending from the anode to the cathode. All the second channels are connected to the first channels. The water pump delivers water containing electrolytes to the water distribution component, allowing the water containing electrolytes to pass through the first and second channels. The water containing electrolytes simultaneously contacts the anode and the cathode, making the anode and the cathode conductive.

[0007] In one embodiment, the electrochemical air purification device further includes a water tank; the water tank is arranged below the mounting base for collecting water flowing out of the mounting base, the input end of the water pump is connected to the water tank, and the output end of the water pump is connected to the upper end of the water distribution component.

[0008] In one embodiment, the water distribution component is a plate-shaped frame, the water distribution component includes a plate body and a plurality of protruding columns disposed on the front and rear surfaces of the plate body, the plurality of protruding columns abutting against the anode and the plurality of protruding columns abutting against the cathode, so as to form gaps between the plate body and the cathode, and between the plate body and the anode.

[0009] In one embodiment, the width of the gap is 0.1mm-10.0mm.

[0010] In one embodiment, the plate includes a plurality of spaced-apart columns and a plurality of connecting rods connecting the columns. The first channel and the second channel are both disposed on the columns. The protruding column is disposed on the columns. The upper end of the first channel is open and the lower end is closed. Alternatively, the water distribution component is a porous ceramic plate.

[0011] In one embodiment, both the anode and the cathode are made of porous materials and have plate-shaped structures. The outer surfaces of the anode and the cathode in the thickness direction are perpendicular to the airflow direction. Air containing gaseous pollutants passes sequentially through the anode, the water distribution component containing electrolyte water, and the cathode, or sequentially through the cathode, the water distribution component containing electrolyte water, and the anode.

[0012] In one embodiment, the distance between the anode and the cathode is 3 mm to 30 mm.

[0013] In one embodiment, the electrochemical air purification device includes multiple sets of electrode units, each set of electrode units including an anode, a cathode and a water distribution element, the water distribution element being disposed between the anode and the cathode.

[0014] In one embodiment, the electrolyte is at least one selected from sulfate, phosphate, carbonate, fluoride, chloride, bromide, iodide, nitrate, borate, citrate, silicate, boron oxide, and phosphorus oxide.

[0015] The present invention also proposes another electrochemical air purification device, comprising: a mounting base, a water pump, multiple anodes, multiple cathodes, and multiple water distribution components. The multiple anodes are disposed within the mounting base and arranged at intervals along the width direction of the mounting base; the multiple cathodes are disposed within the mounting base and arranged at intervals along the width direction of the mounting base, with the cathodes and anodes arranged alternately at intervals; a water distribution component is disposed between each adjacent cathode and anode; the water pump is connected to the water distribution component for circulating water containing electrolytes to the water distribution component. The water distribution component is made of a porous material. The water pump circulates water containing electrolyte to the water distribution component, making the anode and the cathode conductive. The thickness direction of the surfaces of the anode and the cathode is parallel to the airflow direction. Air containing gaseous pollutants passes through the water distribution component between the anode and the cathode.

[0016] The technical solution of this invention employs a circulating water path to ensure a stable passage between the cathode and anode, enabling electrolyte-containing water to continuously and uniformly form an electrolyte water curtain between the anode and cathode, ensuring the continuous and efficient electrochemical reaction, thereby achieving continuous air purification.

[0024] This invention proposes an electrochemical air purification device.

[0025] Please see Figures 1 to 6In one embodiment of the present invention, the electrochemical air purification device includes a DC power supply, an anode 10, a cathode 20, a water distribution component 30, and a water pump. The anode 10 is electrically connected to the positive terminal of the DC power supply; the cathode 20 is electrically connected to the negative terminal of the DC power supply; the water distribution component 30 is disposed between the anode 10 and the cathode 20; the water pump is connected to the water distribution component 30 and is used to circulate and transport water containing electrolytes to the water distribution component 30. The water distribution component 30 is provided with multiple vertically extending first channels 31 and multiple front-to-back extending second channels 32. The multiple second channels 32 are all connected to the first channels 31 and are respectively oriented towards the anode 10 and the cathode 20. The water pump transports the water containing electrolytes to the upper end of the water distribution component 30, so that the water flows from top to bottom under the action of gravity. The water containing electrolytes simultaneously contacts the anode 10 and the cathode 20, making the anode 10 and the cathode 20 conductive. After the anode 10 and the cathode 20 are energized, an electrochemical reaction occurs in the water, generating active species to decompose gaseous pollutants in the air.

[0026] Specifically, in this embodiment, the DC power supply serves as the core energy supply for the entire device, providing the necessary electrical support for the electrochemical reaction. The anode 10 is electrically connected to the positive terminal of the DC power supply, and the cathode 20 is electrically connected to the negative terminal. This connection method creates a stable electric field between the anode 10 and the cathode 20, laying the foundation for the subsequent electrochemical reaction. The water distribution component 30 is a key component for ion conduction. It is located between the anode 10 and the cathode 20 and is used to transport water containing electrolytes to the surfaces of the anode 10 and the cathode 20, ensuring the full implementation of the electrochemical reaction. The water distribution component 30 has multiple cooperating structures, including multiple vertically extending first channels 31 and multiple longitudinally extending second channels 32 (the longitudinal extension direction is perpendicular to the cathode 20 and the anode 10). The first channels 31 are mainly used for longitudinal water flow, while the second channels 32 are used to guide the water flow to the surfaces of the anode 10 and the cathode 20. All second channels 32 are interconnected with the first channels 31, forming a complete flow path to ensure smooth water flow. Meanwhile, the second channel 32 is positioned facing the anode 10 and the cathode 20 respectively, which can deliver water to the surfaces of the two electrodes and avoid purification dead zones caused by uneven water flow distribution.

[0027] The water pump is connected to the water distribution unit 30, and its core function is to realize the circulation and transportation of water containing electrolytes. On the one hand, it transports the water containing electrolytes to the upper end of the water distribution unit 30 to provide a stable water source for water distribution. On the other hand, it cooperates with water circulation to realize the reuse of water resources, reduce operating costs, and avoid water waste. During the operation of the device, the water pump transports the water containing electrolytes to the upper end of the water distribution unit 30. Under the action of gravity, the water flows from top to bottom along the first channel 31 inside the water distribution unit 30, and is evenly dispersed through the second channel 32, forming a continuous and uniform electrolyte water curtain between the anode 10 and the cathode 20. This water curtain can fully cover the surface of the anode 10 and the cathode 20, ensuring that both electrodes can fully contact the electrolyte water.

[0028] The electrolyte water curtain not only enables ion conduction between the anode 10 and cathode 20, forming a stable ion conduction pathway to ensure the smooth occurrence of electrochemical reactions, but also provides ample space for contact between gaseous pollutants and reactive species. When the device is powered on, an electric field is formed between the anode 10 and cathode 20. Under the action of the electrolyte water curtain, an electrochemical reaction occurs, generating highly oxidizing reactive species. These reactive species can rapidly and efficiently oxidize and decompose various gaseous pollutants in the air, including formaldehyde, benzene, and volatile organic compounds, completely destroying the molecular structure of the pollutants and transforming them into harmless substances, thereby achieving the purpose of air purification. Furthermore, the circulating water flow design ensures a stable concentration of electrolyte water, avoiding a decrease in reaction efficiency due to water flow stagnation.

[0029] Furthermore, the electrochemical air purification device also includes a mounting base 40 and a water tank, with the anode 10 and cathode 20 installed inside the mounting base 40; the water tank is arranged below the mounting base 40 for collecting water flowing out of the mounting base 40, the input end of the water pump is connected to the water tank, and the output end of the water pump is connected to the upper end of the water distribution component 30.

[0030] Specifically, in this embodiment, the mounting base 40, as the core support component of the device, is mainly used to fix and position the anode 10 and cathode 20. Both the anode 10 and cathode 20 are securely installed inside the mounting base 40. The internal structure of the mounting base 40 is adapted to the shape of the anode 10 and cathode 20, providing precise positioning for the two electrodes and ensuring that their relative positions remain fixed, thereby guaranteeing a stable distance between them. This design effectively prevents the anode 10 and cathode 20 from shifting positions due to vibration, handling, or long-term use during operation, preventing problems such as uneven electric field distribution and poor ion conduction, thus ensuring the stability of the electrochemical reaction and the consistency of air purification effects. Simultaneously, the mounting base 40 also provides some protection for the anode 10 and cathode 20, preventing direct contact between the electrodes and external objects that could cause wear and damage, extending the service life of the anode 10 and cathode 20, and reducing the maintenance costs of the device.

[0031] The water tank, serving as a storage component of the water circulation system, is positioned to match the mounting base 40, specifically below it. It collects electrolyte-containing water flowing out of the mounting base 40 (which has an opening for water outflow). After the water distributed by the water distribution component 30 completes distribution and electrochemical reaction between the anode 10 and cathode 20, the water flows downwards through the mounting base 40 under gravity and eventually into the water tank below. Therefore, the water tank enables the recovery and recycling of electrolyte-containing water, avoiding water waste caused by leakage, preventing electrolyte loss leading to decreased reaction efficiency, and minimizing the environmental impact of leakage, thus improving the environmental friendliness and economic efficiency of the device.

[0032] To achieve complete water circulation, a precise connection design is adopted between the water pump, water tank, and water distribution component 30. The input end of the water pump is connected to the water tank, enabling continuous and stable extraction of circulating water containing electrolytes collected in the tank, ensuring stable water intake for the pump. The output end of the water pump is connected to the upper end of the water distribution component 30, delivering the extracted circulating water at high pressure and stably to the upper end of the water distribution component 30, providing sufficient power and water source for the uniform water distribution of the water distribution component 30. Through the above connection relationship, a complete water circulation path is formed: water tank → water pump → water distribution component 30 → mounting base 40 → water tank, ensuring the continuity and stability of water circulation. This allows the electrolyte-containing water to continuously and uniformly form an electrolyte water curtain between the anode 10 and the cathode 20, ensuring the continuous and efficient electrochemical reaction, thereby achieving continuous air purification.

[0033] Furthermore, the water distribution component 30 is a plate-shaped frame. The water distribution component 30 includes a plate body 33 and a plurality of protruding columns 34 disposed on the front and rear surfaces of the plate body 33. The plurality of protruding columns 34 abut against the anode 10 and the cathode 20, so as to form a gap 35 between the plate body 33 and the cathode 20, and between the plate body 33 and the anode 10. The width of the gap 35 is 0.1mm-10.0mm.

[0034] Specifically, in this embodiment, the water distribution component 30 adopts a plate-shaped frame structure. As a key component in the device to achieve uniform water distribution and ensure ion conduction, its specific structure and design in conjunction with the anode 10 and cathode 20 are designed to ensure sufficient contact between the electrolyte water and the electrodes, thereby improving purification efficiency. The water distribution component 30 is a plate-shaped frame composed of a plate body 33 and multiple protruding pillars 34. The multiple protruding pillars 34 are respectively disposed on the front and rear surfaces of the plate body 33, and abut against the anode 10 and cathode 20 respectively. The function of this structural design is to form gaps 35 between the plate body 33 and the anode 10, and between the plate body 33 and the cathode 20. The core function of these gaps 35 is to allow the electrolyte-containing water to fully fill them, ensuring that the water flow can fully cover the surfaces of the anode 10 and cathode 20, achieving sufficient contact between the water and the anode 10 and cathode 20.

[0035] The width of gap 35 is controlled within the range of 0.1mm-10.0mm. This size design ensures that the electrolyte water can smoothly fill the gap 35, maximizing the contact area between the water and the anode 10 and cathode 20, avoiding dead zones, and ensuring that the electrochemical reaction can occur fully. It also avoids problems such as excessive water loss and unstable electrolyte concentration due to an overly large gap 35, or poor water flow and gas passage due to an overly small gap 35. Through this gap 35 setting, the electrolyte water can fully wet the surfaces of the anode 10 and cathode 20, providing sufficient contact conditions for the electrochemical reaction, ensuring that active species can fully react with gaseous pollutants, while also ensuring the stability of ion conduction. This improves the purification efficiency and stability of the entire device, and works synergistically with the overall operating logic and other core components of the device to ensure uniform and stable purification results.

[0036] Furthermore, the plate 33 includes a plurality of spaced columns 331 and a plurality of connecting rods 332 connecting the columns 331. The first channel 31 and the second channel 32 are both provided on the columns 331. The protruding column 34 is provided on the columns 331. The upper end of the first channel 31 is open and the lower end is closed.

[0037] Specifically, in this embodiment, the plate 33 of the water distribution component 30 is composed of multiple spaced columns 331 and several connecting rods 332 connecting the columns 331. The columns 331 are evenly spaced along the width of the device, and are interconnected by the connecting rods 332 to form a stable frame structure, ensuring the overall structural stability of the water distribution component 30 and providing basic support for subsequent water flow and electrochemical reactions. The columns 331 of the water distribution component 30 are core functional components. The first channel 31 and the second channel 32 are both located inside each column 331, realizing the longitudinal transmission and lateral dispersion of water flow. Simultaneously, protruding columns 34 are directly disposed on the surface of each column 331, precisely corresponding to the anode 10 and cathode 20, ensuring that the water flow can evenly cover the surfaces of the two electrodes. The first channel 31 on each column 331 is arranged vertically, with an open top and a closed bottom, which allows the water containing electrolyte to flow smoothly from top to bottom, providing a stable water source for the electrochemical reaction; the second channel 32 is connected to the first channel 31 and extends towards the anode 10 and cathode 20, which can accurately deliver the electrolyte water to the electrode surface, ensuring that the electrode and the electrolyte water are in full contact.

[0038] This structural design ensures uniform water distribution while providing ample space for water flow through the cooperation of the column 331 and the connecting rod 332. This ensures that the electrolyte water fully covers the anode 10 and cathode 20, while preventing water accumulation. This provides a guarantee for the smooth progress of subsequent electrochemical reactions and is highly compatible with the overall operating logic of the device, further improving the stability and reliability of the device operation. In some embodiments, the water distribution component 30 is a porous ceramic plate, and this material can also achieve the above-mentioned effects.

[0039] Furthermore, both the anode 10 and the cathode 20 are made of porous materials and have plate-shaped structures. The outer surfaces of the anode 10 and the cathode 20 in the thickness direction are perpendicular to the airflow direction. Air containing gaseous pollutants passes through the anode 10, the water distribution component 30 containing electrolyte water, and the cathode 20 in sequence, or passes through the cathode 20, the water distribution component 30 containing electrolyte water, and the anode 10 in sequence.

[0040] Specifically, please refer to Figures 1 to 6 In this embodiment, both the anode 10 and the cathode 20 are made of porous materials. The porous structure can not only increase the contact area between the electrode and the electrolyte water, providing sufficient reaction space for the smooth progress of the electrochemical reaction, but also facilitate the smooth passage of air, ensuring that the air containing gaseous pollutants can pass smoothly through the electrode and fully contact the electrolyte water and the electrode, providing good conditions for the degradation of pollutants.

[0041] Both the anode 10 and cathode 20 are designed as plate-shaped structures, with an overall flat surface, which facilitates fixed installation on the mounting base 40 and allows for better contact with electrolyte water and air. The outer surfaces of the anode 10 and cathode 20 in the thickness direction are perpendicular to the airflow direction. This structural design allows air containing gaseous pollutants to flow smoothly along a predetermined path. Air can pass sequentially through the anode 10, the water distribution component 30 containing electrolyte water, and the cathode 20, or sequentially through the cathode 20, the water distribution component containing electrolyte water, and the anode 10, ensuring that the air can fully interact with the active species in the electrolyte water and the electrodes during flow, effectively decomposing the gaseous pollutants.

[0042] The selection of porous materials, combined with the plate-shaped structure and vertical airflow design, ensures sufficient contact between the electrolyte water and the electrodes, providing stable support for the electrochemical reaction, while also ensuring smooth airflow so that gaseous pollutants can fully contact the reaction system, maximizing the purification effect and further improving the purification efficiency and stability of the device, thus conforming to the overall operating logic and purification requirements of the device.

[0043] It should be noted that, in this embodiment, the mounting base 40 includes a bottom shell 41 and a cover plate 42. The bottom shell 41 has a cavity structure, and the anode 10, cathode 20, and water distribution component 30 are disposed inside the bottom shell 41. The cover plate 42 covers the bottom shell 41 to fix the internal components inside. The anode 10, cathode 20, and water distribution component 30 are all stacked in a direction parallel to the cover plate 42, arranged from front to back. The bottom wall of the bottom shell 41 and the cover plate 42 are both perforated structures, allowing air to enter the interior through the cover plate 42, pass through the anode 10 and water distribution component 30, and exit through the bottom wall of the cover plate 42. A water inlet groove 47 is provided at the upper end of the bottom shell 41, and at least one water inlet pipe 48 is provided on the side wall of the water inlet groove 47. The water inlet pipe 48 is connected to the output end of the water pump. When in use, the water pump draws water from the water tank to the inlet pipe 48, and then into the inlet tank 47 through the inlet pipe 48, and then into the first channel 31. The water flows from top to bottom to form a water curtain, so that the anode 10 and the cathode 20 are connected.

[0044] Furthermore, the distance between the anode 10 and the cathode 20 is 3mm to 30mm.

[0045] Specifically, in this embodiment, the distance between the anode 10 and the cathode 20 is set between 3mm and 30mm. This distance range provides sufficient space for the smooth flow of electrolyte water, ensuring that the electrolyte-containing water transported by the water distribution component 30 can be evenly filled between the anode 10 and the cathode 20, fully wetting the surfaces of both electrodes and achieving full contact between the electrodes and the electrolyte water, thus providing a stable ion conduction environment for the electrochemical reaction. At the same time, the distance of 3mm to 30mm avoids airflow obstruction and water flow obstruction due to too small a distance, preventing problems such as poor air circulation and insufficient contact between gaseous pollutants and active species. It also avoids insufficient electric field strength and decreased electrochemical reaction efficiency due to too large a distance, ensuring efficient generation of active species and thus guaranteeing the effective decomposition of gaseous pollutants.

[0046] Furthermore, the electrochemical air purification device includes at least one set of electrode units, each set of electrode units including an anode 10, a cathode 20 and a water distribution element 30, the water distribution element 30 being disposed between the anode 10 and the cathode 20, and multiple sets of electrode units being arranged in series along the airflow direction.

[0047] Specifically, in this embodiment, the device can further improve air purification efficiency by combining multiple sets of electrode units, adapting to different usage scenarios with different air volumes and purification needs. This electrochemical air purification device includes at least one set of electrode units, each set of electrode units being an independent purification unit. Its core components are consistent with the aforementioned embodiments, that is, each set of electrode units includes an anode 10, a cathode 20, and a water distribution component 30, wherein the water distribution component 30 is fixedly disposed between the anode 10 and the cathode 20. The three work together to form a complete electrochemical purification unit, capable of independently completing the water distribution, electrochemical reaction, and air purification processes.

[0048] To meet diverse purification needs, multiple electrode units can be arranged in series along the airflow direction. This means that multiple electrode units are arranged sequentially according to the airflow path. Air containing gaseous pollutants must pass through the water distribution element 30 of each electrode unit in sequence. Through multiple electrochemical reactions and degradation of active species, the removal rate of pollutants can be further improved. This design is suitable for scenarios with high concentrations of gaseous pollutants and stringent purification requirements. This combination of multiple electrode units allows the purification capacity of the device to be flexibly adjusted according to actual needs, expanding the device's applicability while balancing purification efficiency and effect. It is also highly compatible with the overall structural design and purification logic of the device.

[0049] Furthermore, both the anode 10 and the cathode 20 are three-dimensional electrodes; the electrolyte is at least one of sulfate, phosphate, carbonate, fluoride, chloride, bromide, iodide, nitrate, borate, citrate, silicate, boron oxide, and phosphorus oxide.

[0050] Specifically, in this embodiment, both the anode 10 and the cathode 20 adopt a three-dimensional electrode structure. Compared with traditional planar electrodes, the three-dimensional electrode can greatly increase the contact area between the electrode and the electrolyte water, and at the same time expand the reaction contact range with gaseous pollutants, making the electrochemical reaction more complete and efficient. The three-dimensional electrode structure design allows the electrolyte water to fully wet the electrode surface, ensuring that every electrode can participate in the reaction and avoiding reaction dead zones. It can also improve ion conduction efficiency, providing a guarantee for the rapid generation of active species, further enhancing the air purification effect. Together with the gap design and water distribution structure mentioned above, it forms a synergistic effect to jointly improve the purification capacity of the device.

[0051] The electrolyte used in this device is selected from at least one of the following: sulfate, phosphate, carbonate, fluoride, chloride, bromide, iodide, nitrate, borate, citrate, silicate, boron oxide, and phosphorus oxide. These electrolyte materials all possess good conductivity and stability, providing sufficient ion support for the electrochemical reaction and ensuring smooth ion conduction between electrodes. Furthermore, single or multiple electrolyte combinations can be flexibly selected according to actual purification needs and water quality conditions. This ensures the stable conduction of the electrochemical reaction and adapts to purification requirements in different scenarios. Combined with the three-dimensional electrode, water distribution structure, and gap design, this further enhances the purification efficiency and operational stability of the device, ensuring the efficient decomposition of gaseous pollutants and guaranteeing consistent purification results.

[0052] In an optional embodiment, this application also provides a horizontal flow electrochemical air purification device, including a mounting base 40, a water pump, multiple cathodes 20, multiple anodes 10, and multiple water distribution elements 30. The multiple anodes 10, cathodes 20, and water distribution elements 30 are all disposed within the mounting base 40. The multiple anodes 10 and multiple cathodes 20 are spaced apart along the width of the mounting base 40, and a water distribution element 30 is disposed between each anode 10 and cathode 20. The water distribution element 30 is made of a porous material. The water pump circulates water containing electrolyte to the water distribution element 30, making the anodes and cathodes conductive. The surfaces of the anodes and cathodes in the thickness direction are parallel to the airflow direction, and air containing gaseous pollutants passes through the water distribution element between the anodes and cathodes.

[0053] Please refer to Figure 7 and Figure 8In this embodiment, another arrangement of the electrochemical air purification device is provided. The core difference from the previous embodiment lies in the arrangement direction of the anode 10 and cathode 20 and the airflow path. In this embodiment, both the anode 10 and cathode 20 are plate-shaped structures. The cathode 20 and anode 10 are arranged in the width direction of the mounting base 40, and the airflow direction is parallel to the surface of the anode 10 and cathode 20 in the thickness direction. At the same time, a water distribution component 30 is still provided between the anode 10 and cathode 20. The water distribution component 30 serves as the core water distribution and reaction carrier, working in conjunction with the two electrodes to achieve air purification. This type of structure is defined as a horizontal flow structure.

[0054] The anode 10 and cathode 20 are arranged relatively parallel to each other, with their surfaces (i.e., the surfaces in the thickness direction) parallel to the airflow direction. This allows air containing gaseous pollutants to flow in a direction parallel to the electrode surface, and the airflow path passes through the area between the anode 10 and cathode 20. A water distribution element 30 is installed in this area, so the airflow must pass through the water distribution element 30 between the anode 10 and cathode 20 to complete the purification process. The water distribution element 30 plays a role in uniformly distributing water and carrying electrolyte water between the two electrodes. The water containing electrolyte, pumped by the water pump, is evenly distributed through the structure of the water distribution element 30, forming a stable electrolyte water layer inside and on the surface of the water distribution element 30, providing a basis for the electrochemical reaction.

[0055] It should be noted that the mounting base 40 in this embodiment includes an upper shell 43, a base plate 44, a left side plate 45, and a right side plate 46, which are connected as a whole to form a through-type frame. The anode 10, cathode 20, and water distribution component 30 are disposed inside the through-type frame. The anode 10, cathode 20, and water distribution component 30 are arranged in a direction extending from the left side plate 45 to the right side plate 46. In this embodiment, air enters the water distribution component 30 from the front side of the mounting base 40 along a direction parallel to the cathode 20 and anode 10, and then exits from the rear side of the mounting base 40. The upper shell 43 has a water inlet groove 47 and a water inlet pipe 48 communicating with the water inlet groove 47, and the output end of the water pump is connected to the water inlet pipe 48.

[0056] In this embodiment, the water distribution element 30 is made of a porous material, such as a sponge-like structure. The porous structure can efficiently adsorb and store electrolyte water, ensuring that the surface of the water distribution element 30 is always covered with a uniform electrolyte water layer, ensuring sufficient contact between the anode 10, cathode 20 and electrolyte water, thereby ensuring that the electrochemical reaction continues to occur stably and generates a sufficient amount of active species. On the other hand, the permeability of the porous structure allows airflow to pass through smoothly without causing significant airflow resistance, while allowing the passing airflow to fully contact the electrolyte water and active species in the water distribution element 30, so that gaseous pollutants are efficiently decomposed and air purification is achieved.

[0057] In this embodiment, the number of anodes 10 and cathodes 20 can be set according to actual needs. Multiple cathodes 20 and anodes 10 are arranged in parallel in the direction perpendicular to the airflow, so that the airflow can pass through multiple water distribution components 30 at the same time, increasing the air handling capacity per unit time and improving the purification efficiency. This is suitable for scenarios with large air volume and requiring rapid air purification.

[0058] The above description is merely an exemplary embodiment of the present invention and does not limit the scope of protection of the present invention. Any equivalent structural transformations made based on the technical concept of the present invention and the contents of the specification and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present invention.
