[0038] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0039] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0040] An air purification assembly 100 according to a first aspect embodiment of the present invention will now be described.

[0041] like Figure 1 As shown, the air purification component 100 is adapted to be installed in the air handling unit 1000 for treating the air flowing through the air handling unit 1000. The specific type of the air handling unit 1000 is not limited, such as an air conditioner, air purifier, humidifier, etc., and is not limited here.

[0042] For example, in some embodiments, the air handling device 1000 may have an air inlet 101 and an air outlet 102. The air purification component 100 is disposed inside the air handling device 1000. Airflow enters the air handling device 1000 through the air inlet 101, is processed by the air purification component 100, and is then discharged to the outside of the air handling device 1000 from the air outlet 102, thereby achieving the effect of air purification. Of course, the present invention is not limited to this. For example, in other embodiments, the air purification component 100 may be disposed outside the air handling device 1000, for example, near the air inlet 101. In this way, the airflow is purified by the air purification component 100 before entering the air handling device 1000 from the air inlet 101 (e.g., ...). Figure 1 As shown), and / or, the air purification component 100 is located near the air outlet 102. When the airflow flows out of the air handling unit 1000 from the air outlet 102, it will be purified by the air purification component 100 and then sent into the environment.

[0043] Combination Figure 2 and Figure 3As shown, the air purification component 100 includes a charged module 1, an electrostatic dust collection module 2, and an electrocatalytic module 3. The electrostatic dust collection module 2 is disposed between the charged module 1 and the electrocatalytic module 3. That is, the charged module 1, the electrostatic dust collection module, and the electrocatalytic module 3 are arranged in sequence. The electrostatic dust collection module 2 includes a surface insulating layer 23 (combined with...). Figure 6 ).

[0044] Therefore, the high-voltage electric field formed between the charged module 1 and the electrocatalytic module 3 allows the catalyst on the surface of the electrocatalytic module 3 to have its surface active sites reorganized. When gaseous pollutants in the air enter the electrocatalytic module 3, the catalyst can catalytically decompose various gaseous pollutants, for example, catalytically oxidizing and decomposing them into CO2 and H2O. For example, when the charged module 1 is connected to the high-voltage electrode and the electrocatalytic module 3 is connected to the ground electrode, the electrocatalytic module 3 can oxidize and reduce gaseous pollutants; while when the charged module 1 is connected to the ground electrode and the electrocatalytic module 3 is connected to the high-voltage electrode, the electrocatalytic module 3 can reduce and oxidize gaseous pollutants. Furthermore, when the electrocatalytic module 3 is connected to the ground electrode, excess electrons can be conducted away by the ground electrode, increasing the catalytic oxidation reaction rate; while when the electrocatalytic module 3 is connected to the high-voltage electrode, it provides the electrons required for the reduction reaction, increasing the reduction reaction rate, thereby improving the purification efficiency and purification effect of the air purification component 100.

[0045] Meanwhile, since the electrostatic dust collection module 2 includes a surface insulating layer 23, dielectric barrier discharge can be achieved through the high-voltage electric field between the electrostatic dust collection module 2 and the charged module 1. This ionizes solid pollutants in the airflow, and the ionized solid pollutants are adsorbed by the electric field of the electrostatic dust collection module 2. For example, when the charged module 1 is connected to a high voltage, the solid pollutants are ionized and become negatively charged, and are adsorbed by the positive electrode of the electrostatic dust collection module 2. Conversely, when the charged module 1 is grounded, the solid pollutants are ionized and become positively charged, and are adsorbed by the negative electrode of the electrostatic dust collection module 2.

[0046] In this way, when indoor air containing solid and gaseous pollutants circulates through the air purification component 100 in its activated state, the airflow first flows through the charged module 1, which ionizes the solid pollutants in the airflow. The airflow then flows through the electrostatic dust collection module 2, where the ionized solid pollutants are adsorbed onto the insulating layer 23 on the surface of the electrostatic dust collection module 2 under the influence of the high-voltage electric field, thus achieving dust removal and sterilization effects. The airflow then flows through the electrocatalytic module 3, where the remaining gaseous pollutants react with the catalyst attached to the surface of the electrocatalytic module 3, achieving effects such as formaldehyde removal and VOCs (volatile organic compounds).

[0047] Furthermore, according to the embodiment of the present invention, the air purification component 100, by providing an electrostatic dust collection module 2 with a surface insulating layer 23 between the charged module 1 and the electrocatalytic module 3, can reduce the ozone generated between the positive and negative electrodes in the high-voltage electric field between the charged module 1 and the electrocatalytic module 3, and can improve the discharge arcing phenomenon between the charged module 1 and the electrocatalytic module 3, further reducing the large amount of ozone generated by the discharge arcing phenomenon. Thus, it can effectively reduce the ozone generated between the charged module 1 and the electrocatalytic module 3 in all aspects, thereby reducing the ozone release of the air purification component 100.

[0048] According to an embodiment of the present invention, the air purification component 100, based on the principle of dielectric barrier discharge plasma, utilizes the electrostatic dust collection function and surface insulation function of the electrostatic dust collection module 2 to improve the arcing phenomenon and ozone generation between the charged module 1 and the electrocatalytic module 3. This allows the air purification component 100 to simultaneously perform functions such as dust removal, sterilization, formaldehyde removal, and VOCs removal, effectively solving the problem of multiple indoor air pollutants. This reduces the number and types of purification components used in the air handling equipment 1000, thereby effectively reducing the overall cost of the air handling equipment 1000, reducing wind resistance, and lowering energy consumption.

[0049] Furthermore, when a suitable surface catalyst is selected for the electrocatalytic module 3, residual ozone can be reacted away, thus achieving the effect of zero ozone release. For example, ozone formed between the charged module 1 and the electrocatalytic module 3 can react with some manganese oxide material at the electrocatalytic module 3 to generate oxygen, thereby further reducing ozone release.

[0050] Based on the target pollutants, air purification technologies can be divided into dust removal and gaseous pollutant removal technologies. Specifically, dust removal technologies include high-efficiency particulate air (HEPA) filters, electrostatic precipitators (IFD, ESP), and ion deposition. Gaseous pollutant removal technologies include adsorption, photocatalysis, ambient temperature catalysis, and plasma methods. However, these technologies are relatively independent, requiring separate purification processes. This necessitates at least two separate purification systems for air handling equipment, one for dust removal and the other for gaseous pollutant removal, resulting in complex structures, high costs, high air resistance, and high energy consumption. Furthermore, electrocatalytic purification technology, which relies on high-voltage discharge to generate ozone groups on the surface, oxidizes and reduces reductive gaseous pollutants. However, this technology suffers from low purification efficiency and generates ozone during the process, limiting its applicability.

[0051] According to an embodiment of the present invention, the air purification component 100 achieves the functions of electrostatic adsorption of solid pollutants and electrocatalytic removal of gaseous pollutants by connecting a conductive substrate with a catalyst-coated surface, i.e., an electrocatalytic module 3, into a high-voltage electric field of an electrostatic dust collection system, and by setting an electrostatic dust collection module 2 with a surface insulating layer 23 between the charged module 1 and the electrocatalytic module 3, while reducing ozone release and improving arcing phenomena between electrodes. In other words, it achieves the purification of gaseous pollutants by high-voltage electrostatic coupling of the catalyst, enabling the purification system to not only remove dust but also efficiently purify various gaseous pollutants without generating ozone, thereby effectively solving the aforementioned technical problems.

[0052] In some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, the charging module 1, the electrostatic dust collection module 2, and the electrocatalytic module 3 are stacked sequentially along the thickness direction of the electrostatic dust collection module 2. That is, the thickness directions of the three modules are the same, and the charging module 1 and the electrocatalytic module 3 are respectively positioned on opposite sides of the thickness of the electrostatic dust collection module 2. The thickness H1 of the electrostatic dust collection module 2 can be 1mm-80mm, allowing for a distance of at least 1mm-80mm between the charging module 1 and the electrocatalytic module 3. For example, the distance between the charging module 1 and the electrocatalytic module 3 can be 1mm, 10mm, 20mm, 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, etc., which can effectively improve the arcing phenomenon between the charging module 1 and the electrocatalytic module 3, reduce the ozone generated between them, and decrease the ozone release.

[0053] Furthermore, the thickness H1 of the electrostatic dust collection module 2 can be 8mm-20mm, thus allowing a distance of at least 8mm-20mm between the charged module 1 and the electrocatalytic module 3. For example, the distance between the charged module 1 and the electrocatalytic module 3 can be 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, etc. This can effectively improve the discharge arcing phenomenon between the charged module 1 and the electrocatalytic module 3, reduce the ozone generated between the charged module 1 and the electrocatalytic module 3, reduce the ozone release, and more effectively, through the high-voltage electric field formed between the charged module 1 and the electrocatalytic module 3, allow the catalyst on the surface of the electrocatalytic module 3 to have its surface active sites reorganized by the high-voltage electric field, so that the electrocatalytic module 3 can better exert its ability to purify gaseous pollutants. It can also effectively ensure the electrostatic dust collection performance of the electrostatic field and better ensure the air volume.

[0054] According to an embodiment of the air purification component 100 of the present invention, the specific selection of the charged module 1 is not limited. For example, it may include at least one of the following: metal wire 111, needle tip, serrated blade, carbon brush, etc., thereby enabling flexible design. It should be noted that, as Figure 3 As shown, the thickness H2 of the charged module 1 is unlimited, for example, it can be 1mm to 90mm. When the charged module 1 includes a tungsten wire, compared with the tip, serrated blade, carbon brush, etc., the size of the protruding part can be reduced, thereby the thickness of the charged module 1 can be better controlled. For example, the thickness of the charged module 1 can be further controlled between 3mm and 15mm.

[0055] For example, in some embodiments of the present invention, such as Figure 3 As shown, the charged module 1 has at least one layer of metal wire 11. When the charged module 1 includes multiple layers of metal wire 11, the multiple layers of metal wire 11 are arranged along the thickness direction of the charged module 1 (e.g., ...). Figure 3 The wire layers (as shown in the vertical direction) are spaced apart. The layer 11 closest to the electrostatic dust collection module 2 (e.g., ...) is a metal wire layer... Figure 3 The distance h1 between the bottommost metal wire layer 11 and the electrostatic dust collection module 2 shown can be 1mm-10mm, for example, 1mm, 2mm, 4mm, 6mm, 8mm, or 10mm. This can effectively prevent electrode breakdown.

[0056] Furthermore, the metal wire layer 11 closest to the electrostatic dust collection module 2 (e.g.) Figure 3 The distance h1 between the bottommost metal wire layer 11 and the electrostatic dust collection module 2 shown can also be 1mm-5mm. For example, it can be 1mm, 2mm, 3mm, 4mm, 5mm, etc. This can effectively prevent electrode breakdown and better ensure that a high-voltage electric field for dielectric barrier discharge is formed between the charging module 1 and the electrostatic dust collection module 2, thereby improving the ionization effect.

[0057] In some embodiments of the present invention, such as Figure 3 and Figure 4 As shown, each metal wire layer 11 can have multiple spaced-apart metal wires 111. For example, the multiple metal wires 111 in each metal wire layer 11 can be spaced apart along a direction perpendicular to the thickness direction of the charged module 1. For example, each metal wire 111 can extend along the length direction of the charged module 1, and the multiple metal wires 111 in the same metal wire layer 11 can be spaced apart along the width direction of the charged module 1. Or, for example, each metal wire 111 can extend along the width direction of the charged module 1, and the multiple metal wires 111 in the same metal wire layer 11 can be spaced apart along the length direction of the charged module 1, and so on. Therefore, the planar space can be utilized more fully, improving the effectiveness of the charged module 1.

[0058] Optionally, the diameter of the metal wire 111 can be 0.1mm-0.3mm, for example, 0.1mm, 0.2mm, 0.3mm, etc. This balances cost and effectiveness.

[0059] Optionally, the spacing W1 between adjacent metal wires 111 can be 5mm-150mm, for example, it can be 5mm, 25mm, 50mm, 75mm, 100mm, 125mm, 150mm, etc. This allows for more efficient use of planar space, improves the effectiveness of the charged module 1, and avoids the metal wires 111 being too densely arranged, which could affect ventilation.

[0060] Optionally, the diameter of the metal wire 111 can be 0.1mm-0.3mm, and the spacing w between adjacent metal wires 111 is 5mm-150mm. This allows for full utilization of the planar space, improves the performance of the charged module 1, avoids the metal wires 111 being too densely arranged and affecting the ventilation effect, and also takes cost into consideration.

[0061] Furthermore, the spacing W1 between adjacent metal wires 111 can be 30mm-80mm. For example, it can be 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, 80mm, etc. This allows for more efficient use of planar space, better improvement of the charging module 1's performance, better avoidance of overly dense metal wire 111 layout affecting ventilation, and avoidance of waste caused by excess metal wires 111.

[0062] The specific selection of the electrostatic dust collection module 2 in the air purification component 100 according to embodiments of the present invention is not limited. For example, in some embodiments, such as Figure 5 and Figure 6 As shown, the electrostatic dust collection module 2 may include multiple first electrode plates 21 and multiple second electrode plates 22. The multiple first electrode plates 21 and multiple second electrode plates 22 are arranged alternately, and adjacent first electrode plates 21 and second electrode plates 22 are spaced apart. Specifically, the width direction of the first electrode plate 21 and the width direction of the second electrode plate 22 are the same as the thickness direction of the electrostatic dust collection module 2, and the thickness direction of the first electrode plate 21 is the same as the thickness direction of the second electrode plate 22. The first electrode plate 21 is located on the thickness side of the second electrode plate 22, and a second electrode plate 22 is disposed between two adjacent first electrode plates 21, and a first electrode plate 21 is disposed between two adjacent second electrode plates 22.

[0063] In some embodiments, such as Figure 8As shown, when the air purification component 100 may include a high-voltage controller 4, the high-voltage controller 4 having a second high-voltage port 42 and a grounding port 43, and the second high-voltage port 42 and the grounding port 43 are respectively connected to the electrostatic dust collection module 2, the second high-voltage port 42 can be connected to the first electrode 21, and the grounding port 43 can be connected to the second electrode 22, thereby realizing the alternating interval of the high-voltage electrode and the ground electrode, and obtaining an electric field capable of adsorbing ionized solid pollutants.

[0064] Optionally, such as Figure 6 As shown, the width k1 of each electrode in the first electrode 21 and the second electrode 22 can be no less than 3mm, that is, greater than or equal to 3mm. For example, it can be 3mm, 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, etc., thus ensuring that the thickness of the electrostatic dust collection module 2 is greater than or equal to 3mm. Therefore, the electrostatic dust collection performance of the electrostatic field can be effectively guaranteed. Furthermore, the arcing phenomenon of discharge between the charged module 1 and the electrocatalytic module 3 can be effectively avoided.

[0065] Furthermore, the width k1 of each electrode in the first electrode 21 and the second electrode 22 can be no less than 8mm and no more than 20mm, for example, it can be 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, etc., so as to ensure that the thickness of the electrostatic dust collection module 2 is between 8mm and 20mm, thereby effectively ensuring the electrostatic dust collection performance of the electrostatic field, effectively avoiding the arcing phenomenon of discharge between the charged module 1 and the electrocatalytic module 3, and ensuring the air volume well.

[0066] Optionally, such as Figure 6As shown, the surface insulating layer 23 covers each of the first electrode 21 and the second electrode 22, and the height of the surface insulating layer 23 protruding from the corresponding electrode on both sides in the width direction of the corresponding electrode is not less than 1 mm, thus effectively meeting the safety creepage height requirements. For example, the width direction of the first electrode 21 is the height direction. The first electrode 21 is covered with the surface insulating layer 23, and the surface insulating layer 23 protrudes upward from the first electrode 21 to form an upper protrusion 231, and the surface insulating layer 23 protrudes downward from the first electrode 21 to form a lower protrusion 232. The height k2 of the upper protrusion 231 and the height k3 of the lower protrusion 232 are both greater than or equal to 1 mm, for example, 1 mm, 2 mm, 3 mm, etc., thus effectively meeting the safety creepage height requirements. For example, the width direction of the second electrode 22 is the height direction. The second electrode 22 is covered with a surface insulating layer 23, and the surface insulating layer 23 protrudes upward from the second electrode 22 to form an upper protrusion 231, and the surface insulating layer 23 protrudes downward from the second electrode 22 to form a lower protrusion 232. The height of each of the upper protrusion 231 and the lower protrusion 232 is greater than or equal to 1 mm, for example, it can be 1 mm, 2 mm, 3 mm, etc., so as to better meet the creepage height requirements of safety regulations.

[0067] Optionally, such as Figure 5 As shown, the distance W2 between adjacent first electrode 21 and second electrode 22 can be 0.1mm-50mm, for example, 0.1mm, 10mm, 20mm, 30mm, 40mm, 50mm, etc. This effectively prevents high voltage from breaking down the surface insulation layer 23 and improves the coverage of the purification electric field.

[0068] Furthermore, such as Figure 5 As shown, the spacing W2 between adjacent first electrode 21 and second electrode 22 can be 1.5mm-3mm. For example, it can be 1.5mm, 1.8mm, 2.1mm, 2.4mm, 2.8mm, 3mm, etc. This can better prevent high voltage from breaking down the surface insulation layer 23 and further improve the coverage of the purification electric field.

[0069] In some embodiments of the present invention, such as Figure 5 As shown, multiple first electrodes 21 and multiple second electrodes 22 can be supported by multiple insulating sheets 24 arranged perpendicular to each electrode and along the length of the electrode, thereby ensuring the spacing between adjacent electrodes and improving the reliability and effectiveness of the purification electric field.

[0070] It should be noted that the specific material of the surface insulating layer 23 is not limited; for example, it can be PP, PET, ABS, PTFE, etc. Furthermore, the electrostatic dust collection module 2 can use an electrostatic dust collection mesh with energy storage function or triboelectric charging. To improve the energy storage performance of the material, PP can be selected. The materials of the first electrode 21 and the second electrode 22 are not limited; for example, they can both be conductive graphite, metal sheets, etc. In some specific examples, conductive graphite can be sprayed onto the surface of the insulating material and then completely covered with the insulating material to obtain an electrode with a surface insulating layer 23, thereby giving the electrostatic dust collection module 2 better electrostatic dust collection and insulation performance.

[0071] The specific selection of the electrocatalytic module 3 in the air purification component 100 according to embodiments of the present invention is not limited. For example, in some embodiments, such as... Figure 7 As shown, the electrocatalytic module 3 includes a porous metal substrate, on the surface of which a catalyst layer is disposed, or on the surface of which a catalyst layer and an adsorption layer are disposed. The porous metal substrate can be a metal honeycomb substrate (such as aluminum-based honeycomb), metal foam, etc. The catalyst layer can include at least one of manganese oxide, Co / Mn composite oxide, Pt / Mn composite oxide, Pt / Au / Mn composite oxide, etc., metal oxides or composites. The adsorption layer can include at least one of activated carbon, molecular sieve, zeolite powder, attapulgite, etc. Each honeycomb pore 31 can penetrate substantially along the thickness direction of the electrocatalytic module 3, thereby meeting ventilation requirements. The porous metal substrate can be connected to the grounding port 43 of the high-voltage controller 4, thereby discharging excess electrons from the oxidation-reduction reaction, cutting off the pathway for electrons to participate in the reaction, increasing the catalytic oxidation reaction rate, and improving the purification efficiency and effect of the air purification component 100. Thus, a good purification effect can be achieved, and the structure is simple.

[0072] Optionally, the porous metal substrate has a mesh size of 1-200 mesh and a porosity of 1%-99%, thus meeting different design requirements. For example, in some embodiments, the porous metal substrate has a mesh size of 3-20 mesh, such as 3 mesh, 5 mesh, 8 mesh, 10 mesh, 12 mesh, 14 mesh, 16 mesh, 18 mesh, 20 mesh, etc., which ensures sufficient contact area between the electrocatalytic module 3 and air, achieving a more effective electrocatalytic effect and ensuring good ventilation. For example, in some embodiments, the porous metal substrate has a porosity of 50%-80%, such as 50%, 60%, 70%, 80%, etc., which also ensures sufficient contact area between the electrocatalytic module 3 and air, achieving a more effective electrocatalytic effect and ensuring good ventilation.

[0073] Optionally, such as Figure 3As shown, the thickness H3 of the electrocatalytic module 3 ranges from 1mm to 80mm, allowing for flexible design. For example, in some embodiments, the thickness H3 of the electrocatalytic module 3 is 10mm to 30mm, ensuring sufficient contact area between the electrocatalytic module 3 and the air, achieving a more effective electrocatalytic effect, and also ensuring adequate ventilation.

[0074] In some embodiments of the present invention, such as Figure 4 , Figure 5 and Figure 7 As shown, each of the charged module 1, the electrostatic dust collection module 2, and the electrocatalytic module 3 may include an insulating frame 5 surrounding its periphery to facilitate assembly and connection.

[0075] In some embodiments of the present invention, the voltage difference between the charging module 1 and the electrocatalytic module 3 is greater than the voltage difference between the electrostatic dust collection module 2 and the electrocatalytic module 3. This allows for the formation of multiple voltage steps, resulting in stronger surface catalyst activity and higher catalytic reaction efficiency in the electrocatalytic module 3, enabling it to better perform its gaseous pollutant purification capabilities.

[0076] In some embodiments of the present invention, such as Figures 8-11 As shown, one of the charging module 1 and the electrocatalytic module 3 is connected to a high voltage while the other is connected to ground. For example, connecting the charging module 1 to a high voltage and the electrocatalytic module 3 to ground allows for the oxidation and purification of reducing gases. Furthermore, grounding the electrocatalytic module 3 dissipates excess electrons from the oxidation reaction, improving its efficiency. Alternatively, connecting the charging module 1 to ground and the electrocatalytic module 3 to a high voltage allows for the reduction and purification of oxidizing gases. Furthermore, connecting the electrocatalytic module 3 to a high voltage provides the electrons needed for the reduction reaction, increasing its rate.

[0077] Therefore, by changing the high-voltage electric field between the charging module 1 and the electrocatalytic module 3, the electrocatalytic module 3 simultaneously possesses both catalytic oxidation and catalytic reduction characteristics. The same electrocatalytic module 3 has the function of catalytically decomposing both oxidizing and reducing gases, enabling it to catalytically decompose both oxidizing and reducing gases. Furthermore, the electrostatic dust collection module 2 is connected to both the high voltage and the ground electrode, thus enabling it to perform electrostatic dust collection.

[0078] For example, in some specific examples, the high voltage connected to the charging module 1 is greater than the high voltage connected to the electrostatic precipitator module 2, and the electrocatalytic module 3 is grounded. Therefore, since both the charging module 1 and the electrostatic precipitator module 2 carry high voltage, and the high voltage connected to the charging module 1 is greater than that connected to the electrostatic precipitator module 2, a double-layer electric field can be effectively formed between the charging module 1 and the electrostatic precipitator module 2, preventing the electric fields from canceling each other out. Furthermore, the high-voltage electric field can enhance the catalytic decomposition performance of the catalyst on the surface of the electrocatalytic module 3, and during the catalytic decomposition process, the generated electrons can be conducted away through the grounding terminal of the electrocatalytic module 3, further increasing the catalytic reaction rate.

[0079] Optionally, when both the charging module 1 and the electrostatic dust collection module 2 are connected to high voltage, the high voltage connected to the charging module 1 is 1kV-4kV higher than the high voltage connected to the electrostatic dust collection module 2. That is, the voltage connected to the charging module 1 is 1kV-4kV higher than the voltage connected to the electrostatic dust collection module 2, for example, 1kV, 2kV, 3kV, 4kV, etc. Alternatively, it can be expressed as: the high voltage connected to the charging module 1 is Vh, and the high voltage connected to the electrostatic dust collection module 2 is Vj, where Vh = Vj + v, and v = 1kV-4kV. This effectively creates a dual-layer electric field interaction between the charging module 1 and the electrostatic dust collection module 2, preventing the electric fields from canceling each other out.

[0080] For example, Vh can be 8kV to 12kV. In some specific examples, the high voltage Vh connected to the charging module 1 is 12kV, and the high voltage Vj connected to the electrostatic dust collection module 2 is 8kV. The electrostatic dust collection module 2 is grounded at the same time, and the electrocatalytic module 3 is grounded. This can create multiple voltage steps, making the surface catalyst of the electrocatalytic module 3 more active and the catalytic efficiency higher, so that the electrocatalytic module 3 can better exert its ability to purify gaseous pollutants.

[0081] Experiments show that, compared with purification components in related technologies that combine needle-plate plasma, electrostatic dust collection mesh, and catalytic filter, the air purification component 100 of this embodiment of the invention achieves a PCADR (clean air delivery rate) of 486m³ / h. 3 / h dropped to 422m 3 / h, FCADR (formaldehyde clean air delivery rate) from 195m 3 / h dropped to 165m 3 / h, toluene CADR from 155m 3 The surface bacteria were basically removed, and the sterilization efficiency increased from 99% every 2 hours to 99% every 1 hour. The experiment used a TA100 wall-mounted air conditioner with an airflow of 580 m³ / h. 3 / h, GB / T18801-2015, voltage 8kV.

[0082] In some embodiments of the present invention, such as Figure 8 and Figure 9 As shown, the charging module 1 and the electrostatic dust collection module 2 are respectively connected to a high-voltage power supply, ensuring that a high-voltage electric field with dielectric barrier discharge is formed between them, so that solid pollutants can be ionized. The electrostatic dust collection module 2 is connected to both the high-voltage power supply and the ground electrode, thereby forming an electric field to adsorb the ionized solid pollutants. The charging module 1 is connected to the high-voltage power supply, while the electrocatalytic module 3 is connected to the ground electrode, thus forming a high-voltage electric field between the charging module 1 and the electrocatalytic module 3. This allows the catalyst on the surface of the electrocatalytic module 3 to have its surface active sites reorganized by the high-voltage electric field, enabling the catalyst to catalytically decompose various gaseous pollutants. However, the invention is not limited to this; the ground electrode can be replaced with other voltages, as long as an effective electric field can be formed, which will not be elaborated here.

[0083] In some embodiments of the present invention, such as Figures 8-9 As shown, the air purification component 100 may include a high-voltage controller 4, which has a first high-voltage port 41, a second high-voltage port 42, and a grounding port 43. The first high-voltage port 41 is connected to the charging module 1, the second high-voltage port 42 and the grounding port 43 are respectively connected to the electrostatic dust collection module 2, and the electrocatalytic module 3 is connected to the grounding port 43. Therefore, the air purification component 100 can be controlled by its own high-voltage controller 4, which is beneficial for application and promotion. Of course, the present invention is not limited to this. For example, in other embodiments of the present invention, the high-voltage controller 4 can also be placed in the electrical control box of the air handling equipment 1000 and electrically connected to the air purification component 100, etc., thereby achieving flexible design.

[0084] It should be noted that the high voltage output of the high voltage controller 4 is not limited. For example, in some embodiments, the high voltage output of the high voltage controller 4 can be 1kV to 20kV, which can better meet the value range requirements of the high voltage Vh connected to the charging module 1 and the high voltage Vj connected to the electrostatic dust collection module 2. However, the present invention is not limited to this. The high voltage output of the high voltage controller 4 can also be specifically set and selected as needed, which is not limited here.

[0085] Hereinafter, with reference to the accompanying drawings, a purification control method for an air purification assembly 100 according to a second aspect embodiment of the present invention will be described.

[0086] According to the purification control method of the present invention, it is used to control the air purification component 100 of any of the first aspects described above. As described above, the air purification component 100 of the first aspect of the present invention is adapted to be disposed in an air handling device 1000 to process the air flowing through the air handling device 1000. The air purification component 100 includes a charged module 1, an electrostatic dust collection module 2 and an electrocatalytic module 3. The electrostatic dust collection module 2 is disposed between the charged module 1 and the electrocatalytic module 3. The electrostatic dust collection module 2 includes a surface insulating layer 23.

[0087] Therefore, as described above, by setting an electrostatic dust collection module 2 with a surface insulating layer 23 between the charged module 1 and the electrocatalytic module 3, the arcing phenomenon between the charged module 1 and the electrocatalytic module 3 can be improved, reducing the ozone generated between the charged module 1 and the electrocatalytic module 3, thereby reducing the ozone release of the air purification component 100. Furthermore, by setting the charged module 1, the electrostatic dust collection module 2, and the electrocatalytic module 3, comprehensive purification of both solid and gaseous pollutants in the airflow can be achieved, making the air purification component 100 highly functional.

[0088] Specifically, the purification control method according to an embodiment of the present invention may include: determining the gas type of indoor air pollutants, wherein the gas type of indoor air pollutants includes reducing gases and oxidizing gases; and controlling the power supply to the charging module 1 and the electrocatalytic module 3 according to the gas type of indoor air pollutants, so that the air purification component 100 operates in different purification modes.

[0089] Therefore, by adopting different power supply control schemes for the electrocatalytic module 3 for different types of air pollutants, the same air purification component 100 can possess both catalytic oxidation and catalytic reduction characteristics, and can perform the dual function of catalytic decomposition of oxidizing and reducing gases. However, ordinary catalytic filters in related technologies generally only have the function of catalytic oxidation and decomposition of one type of gaseous pollutant, such as manganese oxide catalytic oxidation and reduction of formaldehyde, and Cu / Mn catalytic reduction of NO.

[0090] In short, the purification control method of the air purification component 100 according to the embodiment of the present invention involves setting an electrostatic dust collection module 2 with a surface insulating layer 23 between the charged module 1 and the electrocatalytic module 3, and controlling the power supply to the charged module 1 and the electrocatalytic module 3 according to the gas type of indoor air pollutants, thereby changing the high-voltage electric field introduced between the charged module 1 and the electrocatalytic module 3, which activates the surface potential of the electrocatalytic module 3, enabling the electrocatalytic module 3 to catalytically decompose oxidizing and reducing gases. Through the insulating effect of the electrostatic dust collection module 2, the discharge arcing effect and ozone generation between the charged module 1 and the electrocatalytic module 3 are reduced.

[0091] In some embodiments, combined with Figure 12 The power supply control for the charged module 1 and the electrocatalytic module 3 is based on the gas type of indoor air pollutants, including: when the indoor air pollutants are reducing gases, controlling the electrocatalytic module 3 to be grounded and controlling the charged module 1 to be connected to high voltage to oxidize the reducing gases.

[0092] For example, when the gaseous pollutant analyzer detects indoor pollutants as reducing gases, such as formaldehyde and VOCs, the high-voltage controller 4 outputs a Class O purification mode to the electrocatalytic module 3. This means that the electrocatalytic module 3 is grounded, and the charging module 1 is connected to a high voltage. The high-voltage electric field reforms the active sites on the catalyst surface, enabling the catalyst to catalyze the oxidation and reduction of gases. Grounding the catalyst surface can conduct away excess electrons from the oxidation and reduction reaction, promoting the positive reaction and thus cutting off the pathway for electrons to participate in the reaction, improving the efficiency of the catalytic oxidation reaction, and enhancing the purification efficiency and effect of the air purification component 100.

[0093] In some embodiments, combined with Figure 12 The power supply control for the charged module 1 and the electrocatalytic module 3 is based on the gas type of indoor air pollutants, including: when the indoor air pollutants are oxidizing gases, controlling the electrocatalytic module 3 to connect to a high-voltage pulse and controlling the charged module 1 to ground, so as to reduce the oxidizing gases.

[0094] For example, when the gaseous pollutant analyzer detects oxidizing gases such as O3 and NO as indoor pollutants, the air purification component 100 outputs a Class C purification mode to the electrocatalytic module 3. This means the high-voltage controller 4 outputs a grounded electrode to the charged module 1 and a high-voltage electrode to the electrocatalytic module 3, enabling non-Radidatic electrochemical modification of the catalyst. The catalyst catalyzes the reduction of oxidizing gases and provides electrons to the reaction, promoting the positive reaction. Furthermore, when the high-voltage controller 4 outputs the Class C purification mode to the electrocatalytic module 3, it outputs pulsed electricity to both the charged module 1 and the electrocatalytic module 3. For example, the pulse voltage is 0-20kV, the frequency range is 0-7.3kHz, and the pulse width is 0-100μs. The electrocatalytic module 3 is connected to high voltage, and the charged module 1 is grounded. This allows the catalyst to undergo non-Radidatic electrochemical modification, catalyzing the reduction of oxidizing gases. The catalyst surface receives high-voltage electricity to supplement electrons, promoting the positive reaction. Moreover, by providing the electrons required for the reaction through the high voltage connection to the electrocatalytic module 3, the reduction reaction rate is increased.

[0095] Therefore, according to the purification control method of the air purification component 100 of the present invention, by inputting high voltage to the opposite electrode of the electrocatalytic module 3, and through reforming the catalyst surface potential and non-Radidatic electrochemical modification, the electrocatalytic module 3 simultaneously possesses both catalytic oxidation and catalytic reduction characteristics. The same electrocatalytic module 3 has the function of catalytically decomposing oxidizing and reducing gases. Furthermore, by grounding the electrocatalytic module 3, excess electrons in the oxidation reaction are dissipated, improving the oxidation reaction efficiency; while by connecting the electrocatalytic module 3 to high voltage, electrons required for the reduction reaction are provided, increasing the rate of the reduction reaction.

[0096] In some embodiments, combined with Figure 12 The power supply control for the charged module 1 and the electrocatalytic module 3 is based on the gas type of indoor air pollutants, including: when the indoor air pollutants include reducing gases and oxidizing gases, controlling the air purification component 100 to periodically switch between a first purification mode and a second purification mode, wherein the electrocatalytic module 3 is grounded and the charged module 1 is connected to a high voltage so that the air purification component 100 operates in the first purification mode; the electrocatalytic module 3 is connected to a high voltage pulse and the charged module 1 is grounded so that the air purification component 100 operates in the second purification mode.

[0097] Therefore, by controlling the air purification component 100 to periodically switch between the first purification mode (such as the O-type purification mode described above) and the second purification mode (such as the C-type purification mode described above), the electrocatalytic module 3 can have both catalytic oxidation and catalytic reduction characteristics. The same electrocatalytic module 3 can have the dual function of catalytic decomposition of oxidizing and reducing gases, thereby effectively purifying reducing and oxidizing gases in indoor air pollutants.

[0098] Furthermore, combined Figure 12 The air purification component 100 is controlled to periodically switch between a first purification mode and a second purification mode, including: determining the concentrations of reducing gas po and oxidizing gas pc in indoor air pollutants, and determining the ratio between the concentrations of reducing gas and oxidizing gas; and controlling the working time of the first purification mode and the second purification mode in each cycle according to the ratio.

[0099] For example, when the gaseous pollutant analyzer detects both oxidizing and reducing gases in the indoor air, the high-voltage controller 4 outputs a Class S purification mode to the electrocatalytic module 3. Based on the ratio of the oxidizing gas concentration pc to the reducing gas concentration po, the operating time to of the first purification mode (as described above in Class O purification mode) and the operating time tc of the second purification mode (as described above in Class C purification mode) are determined, i.e., po:pc = to:tc. This allows for more thorough, effective, and energy-efficient purification of both reducing and oxidizing gases in indoor air pollutants.

[0100] Furthermore, combined Figure 12 After the air purification component 100 periodically switches between a first purification mode and a second purification mode, the method further includes: when the reducing gas concentration po is greater than or equal to a first preset concentration value Omax and the oxidizing gas concentration pc is less than a second preset concentration value Cmax, controlling the air purification component 100 to continuously operate in the first purification mode (as described above in the O-type purification mode). This allows for effective purification of reducing gases in indoor air pollutants.

[0101] Furthermore, combined Figure 12 After the air purification component 100 periodically switches between the first purification mode and the second purification mode, the method further includes: when the reducing gas concentration po is less than the first preset concentration value Omax and the oxidizing gas concentration pc is greater than or equal to the second preset concentration value Cmax, controlling the air purification component 100 to continue operating in the second purification mode (as described above in the Class C purification mode). This allows for effective purification of oxidizing gases in indoor air pollutants.

[0102] Furthermore, combined Figure 12 After the air purification component 100 periodically switches between the first purification mode and the second purification mode, the method further includes: when the reducing gas concentration po is less than the first preset concentration value Omax and the oxidizing gas concentration pc is less than the second preset concentration value Cmax, controlling the air purification component 100 to stop working and stop purification, thereby achieving the effect of energy saving.

[0103] In some embodiments, combined with Figure 12When controlling the power supply to the charged module 1 and the electrocatalytic module 3 according to the gas type of indoor air pollutants, the method further includes: determining the indoor air dust concentration, determining the air purification efficiency based on the indoor air dust concentration, and controlling whether the electrostatic dust collection module 2 is charged based on the air purification efficiency.

[0104] For example, when the purification mode is activated, a dust tester, such as a dust sensor, monitors the indoor air dust concentration in real time. The output is processed and analyzed to determine whether the purification efficiency meets the set value Pmin. When the purification efficiency is greater than or equal to Pmin, the high-voltage controller 4 prevents the electrostatic dust collection module 2 from outputting high voltage. When the purification efficiency is less than Pmin, the high-voltage controller 4 controls the electrostatic dust collection module 2 to output a charging mode P. By monitoring changes in indoor air quality in real time through the dust tester, the electrostatic dust collection module 2 is no longer charged once the purification efficiency meets Pmin. This effectively ensures the purification effect.

[0105] Hereinafter, a computer-readable storage medium according to an embodiment of a third aspect of the present invention will be described.

[0111] For example, in some embodiments, the air handling device 1000 may have an air inlet 101 and an air outlet 102. The air purification component 100 is disposed inside the air handling device 1000. Airflow enters the air handling device 1000 through the air inlet 101, is processed by the air purification component 100, and is then sent out to the outside of the air handling device 1000 from the air outlet 102, thereby achieving the effect of air purification. Of course, the present invention is not limited to this. For example, in other embodiments, the air purification component 100 may be disposed outside the air handling device 1000, for example, near the air inlet 101. In this way, the airflow is purified by the air purification component 100 before entering the air handling device 1000 from the air inlet 101, and / or, the air purification component 100 is disposed near the air outlet 102. When the airflow flows out of the air handling device 1000 from the air outlet 102, it is purified by the air purification component 100 before being sent into the environment.
