Description

Electrode assembly, adsorption unit and gas particulate matter purification device Technical Field

[0001] This invention relates to the field of gas purification technology, specifically to an electrode assembly, an adsorption unit, and a gas particulate matter purification device. Background Technology

[0002] As people become increasingly environmentally conscious, their understanding of and demand for purification of air pollutants (including but not limited to smoke, dust, VOCs, and engine exhaust) are constantly rising. Consequently, more and better purification technologies are being installed and used in vehicles, factories, and homes. Among these technologies, electrostatic precipitator technology is widely used. The principle of electrostatic precipitator technology is that gas is ionized when it passes through an electrostatic field. Particulate matter in the gas combines with charged ions and tends to move towards the electrode with the opposite polarity of the charged ions, thus depositing. Therefore, the particulate matter removal rate is related to the charge efficiency of the particulate matter. However, most devices are manually assembled, making it difficult to mold into a single unit and mass-produce. Summary of the Invention

[0077] Example 1

[0078] This embodiment provides a gas particulate matter purification device. Referring to Figures 1 to 7, the gas particulate matter purification device 3 includes an adsorption unit 31 and a discharge unit 32. The discharge unit 32 includes a discharge beam 321, which comprises multiple metal wires and / or conductive non-metal wires. One end of each wire is fixed together to form a fixed end 322, while the other ends are dispersed to form free ends 323. Along the airflow direction, the gas sequentially passes through the free end 323 of the discharge beam 321, the fixed end 322 of the beam 321, and the adsorption unit 31. Particulate matter includes micron- and nano-sized particles such as dust, bacteria, and viruses. This design allows for better removal of particulate matter from the gas, especially airborne particles, achieving air purification.

[0079] In one embodiment of the present invention, the adsorption unit 31 includes two electrode assemblies, namely a first electrode assembly 311 and a second electrode assembly 312. The first electrode assembly 312 has a certain preset voltage, and the second electrode assembly 313 is grounded. The first electrode assembly 311 is an integrally formed structure and includes a first electrode connector 3111 and a plurality of first electrodes 3112. The second electrode assembly 312 is an integrally formed structure and includes a second electrode connector 3121 and a plurality of second electrodes 3122. The features of the second electrode connector 3121 and the plurality of second electrodes 3122 of the second electrode assembly 312 can be referred to the features of the first electrode connector 3111 and the plurality of first electrodes 3112 of the first electrode assembly 311. The first electrode 3112 has a certain fixed preset voltage, and the second electrode 3122 is grounded. The first and second names in the first electrode connector 3111 and the second electrode connector 3121 are only for distinguishing their relationship and can be collectively referred to as electrode connectors. The first and second names in the first electrode 3112 and the second electrode 3122 are only for distinguishing their relationship and can be collectively referred to as electrodes. The electrode assembly is described using the first electrode assembly 311 as an example. The features of the second electrode assembly 312 can be referred to those of the first electrode assembly 311, and the similarities will not be repeated.

[0080] Optionally, the first electrode assembly 311 is an integrally formed structure and includes a first electrode connector 3111 and a plurality of first electrodes 3112. The first electrodes 3112 are hollow tubular, and the plurality of first electrodes 3112 are coaxially mounted and have two open ends 313, which are respectively a first end 3131 and a second end 3132. For example, the first electrode 3112 can be a cylindrical hollow tube, and the plane on which the plurality of first electrodes 3112 are coaxially mounted and have two open ends 313 can be regarded as two circular end faces of the plurality of first electrodes 3112 assembled together. The first end 3131 of the plurality of first electrodes 3112 is provided with a first electrode connector 3111. The first electrode connector 3111 includes at least one connecting rod 314, and each connecting rod 314 is connected to at least two first electrodes 3112 and spans the gap 315 between adjacent first electrodes 3112. The hollow tubular cross-section perpendicular to the axis can be circular or polygonal (triangular, quadrilateral, pentagonal, hexagonal, etc.). This design enables automated mass production of electrode assemblies; for example, injection molding allows for rapid prototyping of the electrode assemblies, rather than manually assembling the connectors and electrodes.

[0081] Optionally, each connecting rod 314 is arranged along the radial direction of the first electrode 3112. This not only ensures that the electrode assembly has excellent structural strength, but also that the electrode assembly has reliable electrical performance.

[0082] Optionally, in the coaxially assembled plurality of first electrodes 3112, the number of connecting rods 314 on the outer first electrodes 3112 is greater than the number of connecting rods 314 on the inner first electrodes 3112. For example, in this embodiment, seven first electrodes 3112 are coaxially assembled, with 16 connecting rods 314 on the four outer first electrodes 3112 and eight connecting rods 314 on the three inner first electrodes 3112. In this embodiment, at least one connecting rod 314 is connected to each electrode and spans the gap 315 between adjacent electrodes, and at least one connecting rod is connected to the inner electrode and spans the gap 315 between adjacent electrodes. For example, eight connecting rods 314 are connected to each first electrode 3112 and span the gap 315 between adjacent first electrodes 3112, and eight connecting rods 314 are connected to the inner first electrode 3112 and span the gap 315 between adjacent first electrodes 3112. Each connecting rod 314 can be adapted to the circumference length of each electrode, so that electrodes with a larger outer circumference length receive more support from the connecting rods, while electrodes with a smaller inner circumference length receive correspondingly less support from the connecting rods 314. This not only saves materials, but also provides a balanced radial constraint force during overall injection molding, preventing electrode deformation.

[0083] Optionally, the connecting rod 314 includes a first surface 3142 facing outward of the first electrode assembly 311 and a second surface (not shown in the figure) facing inward of the first electrode assembly 311. The plane containing the first surface 3143 is coplanar with the plane containing the end faces of the first ends 3131 of the plurality of first electrodes 3112. This makes the mold structure extremely simple during integrated molding, and the cavity on the mold corresponding to this part of the structure can be a simple plane, reducing processing difficulty and cost, improving precision, and avoiding molding defects.

[0084] Optionally, the connecting rod 314 includes a groove 3141. The connecting rod 314 includes a first surface 3142 facing outward of the first electrode assembly 312 and a second surface (not shown) facing inward of the first electrode assembly 312. Those skilled in the art will understand that the first surface 3142 and the second surface are arranged opposite to each other. The first surface 3142 is recessed into the second surface to form the groove 3141, or the second surface is recessed into the first surface 3142 to form the groove. In this embodiment, the first surface 3142 is recessed into the second surface to form the groove 3141. The circumferential width of the connecting rod 314 is greater than the thickness of the electrode, which can improve the structural strength of the electrode assembly. However, in the integral molding process, such as injection molding, the electrode assembly (especially the electrode) is prone to deformation. Therefore, a groove 3141 is provided in the connecting rod 314. Preferably, the wall thickness of the groove 3141 is the same as the thickness of the electrode. This technical feature is described in detail in another embodiment below.

[0085] Optionally, referring to Figure 2, the connecting rod 314 located at the gap 315 is provided with a groove 3141. That is, the groove 3141 on the connecting rod 314 is provided in a segmented manner. For example, in the first electrode assembly 311, the groove 3141 of the connecting rod 314 of the first electrode connector 3111 is provided as follows: the connecting rod 314 located at the gap 315 is provided with a groove 3141. It can be understood that the first electrode 3112 still exists inside the connecting rod 314. Although the first electrode 3112 located in the groove 3141 has no adsorption effect, and the area ratio of this part of the first electrode relative to the overall first electrode is very small, it has almost no impact on the adsorption effect, but it can provide a certain support for the connecting rod 314.

[0086] Optionally, referring to Figure 4, the groove 3141 extends radially on the connecting rod 314, meaning the groove 3141 is continuous on the connecting rod 314. For example, in the second electrode assembly 312, the groove 3141 on the connecting rod 314 of the second electrode connector 3121 is arranged such that the groove 3141 extends radially on the connecting rod 314. That is, the second electrode 3122 is discontinuous at the connecting rod 314.

[0087] Optionally, at least one of the multiple first electrodes 3112 has a clearance groove 3132 at its second end. This can be understood as the edge of the second end 3132 of the first electrode 3112 being recessed towards the first end 3131 to form a notch, which is the clearance groove 316. There are two ways of recessing. The first is that all edges of the second end 3132 of the first electrode 3112 are recessed towards the first end 3131 to form a clearance groove. For example, all edges of the second ends 3132 of the two inner first electrodes 3112 are recessed towards the first end 3131 to form a clearance groove, and the clearance groove is annular. The second is that a certain edge of the second end 3132 of the first electrode 3112 is recessed towards the first end 3131 to form a clearance groove. For example, a certain edge of the second ends 3132 of the five outer first electrodes 3112 is recessed towards the first end 3131 to form a clearance groove, and the clearance groove has a structure similar to an arc or rectangle. The clearance groove 316 is configured to correspond to the position of the connecting rod 314 of the second electrode 3122, which is interlocked with the first electrode 3112, in order to achieve clearance. The size of the clearance groove 316 is configured to be greater than or equal to the size of the connecting rod 314 of the second electrode 3122, which is interlocked with the first electrode 3112.

[0088] Optionally, the size of the clearance groove 316 of the first electrode 3112 is configured to be larger than the size of the connecting rod 314 of the second electrode 3122, which is interlocked with the first electrode 3112. This is so that when the connecting rod 314 of the second electrode 3122 is disposed within the clearance groove 316, the edge of the clearance groove 316 and the connecting rod 314 of the second electrode 3122 have a second predetermined distance. The clearance groove of the second electrode 3122 and the connecting rod of the first electrode 3112 are similarly configured. For example, the length of the clearance groove 316 of the second electrode 3122 is greater than the length of the connecting rod 314 of the first electrode 3112, and the width of the clearance groove 316 of the second electrode 3122 is greater than the width of the connecting rod 314 of the first electrode 3112. When the connecting rod 314 of the second electrode 3122 is disposed within the clearance groove 316, the clearance groove 316 of the second electrode 3122 and the connecting rod 314 of the first electrode 3112 do not contact each other. The second electrode 3122 or the first electrode 3112 constitutes the entire working area, which includes the substrate and conductive layers disposed on both sides of the substrate. With this design, the second preset distance can be adjusted according to the actual voltage, and the first electrode 3112 and the second electrode 3122 will not short-circuit.

[0089] In one embodiment of the present invention, the second end 3121 of the first electrode 3112 and the second end 3121 of the second electrode 3122 are inter-inserted and assembled so that the first electrode 3112 and the second electrode 3122 are coaxially assembled and the first electrode 3112 and the second electrode 3122 are alternately arranged in the radial direction.

[0090] Optionally, a first opening 3113 is formed between the second ends 3121 of adjacent first electrodes 3112, and a second opening 3123 is formed between the second ends 3121 of adjacent second electrodes 3122. Multiple connected first electrodes 3112 are inserted into the space between the multiple connected second electrodes 3122 through the second opening 3123, and multiple connected second electrodes 3122 are inserted into the space between the multiple connected first electrodes 3112 through the first opening 3113. After assembly, the connecting rod 314 of the first electrode assembly 311 is disposed within the clearance groove 316 of the second electrode assembly 312, and the connecting rod 314 of the second electrode assembly 312 is disposed within the clearance groove 316 of the first electrode assembly 311.

[0091] In one embodiment of the present invention, the gas particulate matter purification device 3 further includes a housing 33, with the adsorption unit 31 and the discharge unit 32 disposed within the housing 33, which is also grounded. The electrode adjacent to the housing 22 is the first electrode 3112, so the housing disposed next to the first electrode 3112 of the adsorption unit 31 can also have the same function as the second electrode 3122, adsorbing particulate matter in the air. Since the discharge beam 321 of the discharge unit 32 has a certain voltage, the discharge beam 321 and the housing disposed next to the discharge beam 321 can also form an electric field to adsorb a certain amount of particulate matter.

[0092] In one embodiment of the present invention, the adsorption unit 31 further includes a conductive support frame 317 disposed at the first end 3131 of the second electrode 3122. The conductive support frame 317 is connected to the connecting rod 314 of the second electrode connector 3121 and the outer casing 33, respectively. The edge of the conductive support frame 317 extends beyond the radial edge of the outermost second electrode 3122. The distance between the edge of the conductive support frame 317 and the radial edge of the outermost second electrode 3122 is a third preset distance. Preferably, the third preset distance = 2 × the inter-electrode spacing between the first electrode and the second electrode + the thickness of the first electrode. The conductive support frame 317 can serve as a positioning element, so that when the adsorption unit 31 is installed inside the outer casing 22, the distance between the first electrode 3112 and the outer casing 22 is equal to the inter-electrode spacing between the first electrode 3112 and the second electrode 3122.

[0093] In one embodiment of the present invention, when the size of the clearance groove 316 is configured to be larger than the size of the connecting rod 314 of another electrode that is interlocked with the electrode, the innermost electrode of the second electrode 3122 is provided with a second electrode connecting plate 3124. The adsorption unit 31 also includes an insulating connector 318 disposed at the first end 3131 of the first electrode 3122. The insulating connector 318 is connected to the connecting rod 314 of the first electrode connector 3111 and the second electrode connecting plate 3124 respectively. The insulating connector 318 can play a role in installation positioning when the first electrode assembly 311 and the second electrode assembly 312 are installed together, ensuring that the electrode spacing between the first electrode 3112 and the second electrode 3122 is the same everywhere.

[0094] Optionally, the second end 3132 of the innermost second electrode 3122 extends radially toward the axial direction to form a second electrode connecting plate 3124. The second electrode connecting plate 3124 is connected to the middle of the insulating connector 318, and the edge of the insulating connector 318 extends beyond the radial edge of the outermost first electrode 3112. The distance between the edge of the insulating connector 318 and the radial edge of the outermost first electrode 3112 is a fourth preset distance. Preferably, the fourth preset distance is equal to the electrode spacing between the first electrode and the second electrode. The insulating connector 318 can serve as a positioning element, so that when the adsorption unit 31 is installed inside the housing 22, the distance between the first electrode 3112 and the housing 22 is equal to the electrode spacing between the first electrode 3112 and the second electrode 3122.

[0095] In one embodiment of the present invention, the gas particulate matter purification device 3 further includes a fan 34 and a humidification mechanism 35. Along the airflow direction, the gas sequentially passes through the free end 323 of the discharge beam 321, the fixed end 322 of the discharge beam 321, the adsorption unit 31, the fan 34, and the humidification mechanism 35. The fan 34 and the humidification mechanism 35 are integrally disposed at the outlet end of the gas particulate matter purification device 3. An air inlet (not shown in the figure) is provided at the bottom of the gas particulate matter purification device. The gas sequentially passes through the discharge unit 32 and the adsorption unit 31 along the axial direction. After passing through the fan 34, the gas enters the humidification mechanism 35 in the radial direction and exits the humidification mechanism 35 in the radial direction. This design results in low gas resistance, a compact device, and better purification effect.

[0096] In one embodiment of the present invention, the humidification mechanism 35 includes a housing 351 and a wet curtain 352. The housing 35 includes an inner sidewall 3511 and an outer sidewall 3512 coaxially arranged, forming an annular chamber 353 between the inner sidewall 3511 and the outer sidewall 3512. The inner sidewall 3511 is provided with a first air inlet 3541, and the outer sidewall 3512 is provided with an air outlet 3542. The wet curtain 352 is disposed in the annular chamber 353. Gas enters the annular chamber 353 from the first air inlet 3541, passes through the wet curtain 352 for humidification, and then leaves the annular chamber 353 from the air outlet 3542.

[0097] Optionally, the housing 351 further includes a bottom plate 3513 disposed below the annular chamber 353. The bottom of the inner sidewall 3511 and the outer sidewall 3512 are respectively provided with an inner baffle 3514 and an outer baffle 3515. The inner baffle 3514, the outer baffle 3515, and the bottom plate 3513 enclose a water storage tank 355. The bottom of the evaporative cooling pad 352 is disposed within the water storage tank 355. The evaporative cooling pad 352 absorbs water from the water storage tank 355, and gas passing through the evaporative cooling pad 352 can be humidified.

[0098] Optionally, the housing 351 also includes a top cover 3516 disposed above the annular chamber 353, and the inner sidewall 3511 includes a plurality of connecting arms 35111. The two ends of the connecting arms 35111 are respectively connected to the inner baffle 3514 and the top cover 3516, and a first air port 3541 is formed between two adjacent connecting arms 35111.

[0099] Optionally, the evaporative cooling pad 352 includes a sheet that is repeatedly folded, with its two ends joined together to form a ring structure. The sheet includes porous fiber paper. The two ends of the sheet can be connected by adhesive, heat fusion, or sewing. The porous fiber paper includes wood pulp fiber paper, glass fiber paper, or plant fiber composite paper.

[0100] Alternatively, the evaporative cooling pad 352 can also be made of materials and structures found in existing technologies. In terms of materials, the evaporative cooling pad can be made of plant fibers or synthetic materials. Common synthetic materials include honeycomb paper-based evaporative cooling pads, plastic evaporative cooling pads, fiberglass evaporative cooling pads, and ceramic evaporative cooling pads. In terms of structure, the evaporative cooling pad can have a regular honeycomb structure, for example, by processing sheets into continuous, uniform honeycomb or corrugated corrugations, then stacking and bonding them to form numerous small, uniformly oriented vertical air ducts; an interlaced grid or corrugated plate structure, for example, composed of multiple layers of parallel plastic or metal wire mesh, or corrugated plates at angles to each other, interlaced to form tortuous air channels, which can also effectively increase the contact area; a loosely filled structure, where regularly spaced fillers such as plastic balls, Raschig rings, or Pall rings are loosely filled into a frame as the evaporative cooling pad; or a fabric roller blind structure, using a continuous roller blind made of non-woven fabric, felt, or special absorbent fabric.

[0101] Optionally, the top cover 3516 and the inner sidewall 3511 enclose a fan chamber 356, with a fan 34 disposed within the fan chamber 356. A second air inlet 3543 is provided at the bottom of the fan chamber 356. Gas enters the fan chamber 356 through the second air inlet 3543, passes through the fan 34, and then enters the annular chamber 353 through the first air inlet 3541. The fan 34 can be fixedly connected to the top cover 3516, which can be composed of multiple plates. For example, some plates can be positioned above the fan chamber 356 and fixedly connected to the fan, while others can be positioned above the annular chamber 353. The plates positioned above the annular chamber 353 can be integrally formed with the outer sidewall 3512. With this design, the gas sequentially passes through the discharge unit 32 and the adsorption unit 31 along the axial direction. After passing through the fan 34, the gas enters the humidification mechanism 35 along the radial direction and exits the humidification mechanism 35 along the radial direction. This design reduces gas resistance, makes the device compact, and improves purification efficiency.

[0102] Those skilled in the art will recognize that the gas particulate matter purification device 3 may also include a fan support (not shown in the figure), with the fan support, top cover 3516, and inner sidewall 3511 enclosing a fan chamber 356. A fan 34 is disposed within the fan chamber 356. A second air inlet 3543 is provided on the fan support at the bottom of the fan chamber 356. Gas enters the fan chamber 356 through the second air inlet 3543, passes through the fan 34, and then enters the annular chamber 353 through the first air inlet 3541. The fan 34 may also be mounted on the fan support.

[0103] Example 2

[0104] This embodiment provides an electrode assembly. The electrode assembly of this embodiment can be used as the first electrode assembly or the second electrode assembly of the gas particulate matter purification device of Embodiment 1. This embodiment only describes the differences from the electrode assembly in Embodiment 1, and the similarities will not be repeated.

[0105] Referring to Figure 8, the dimensions of the clearance groove 316 are configured to match the dimensions of the connecting rod 314 of the other electrode in the interlocking assembly, so that the connecting rod 314 of the electrode snaps into the clearance groove 316 of the other electrode. This design simplifies the assembly structure; for example, the insulating connector of Embodiment 1 can be omitted because the clearance groove can function as a snap-fit ​​groove, and the connecting rod 314 can snap into the clearance groove 316 of the other electrode, completing the positioning assembly.

[0106] Optionally, the electrode includes a working area 41 (outside the dashed line) and a connecting area 42 (inside the dashed line). The connecting area 42 is formed by extending a first preset distance inward from the edge of the clearance groove 316. The electrode outside the connecting area 42 is the working area 41. The working area 41 consists of a substrate and conductive layers disposed on both sides of the substrate, and the connecting area 42 is the substrate. The connecting area 42 does not contain any conductive layer material, which prevents short circuits after the two electrode assemblies are assembled. The first preset distance can be adjusted according to the actual voltage.

[0107] In this embodiment, at least one connecting rod 314 is connected to the outer electrode and spans the gap between adjacent electrodes, and at least one connecting rod 3114 is connected to the inner electrode and spans the gap between adjacent electrodes. For example, 16 connecting rods 314 are connected to the four outer electrodes and span the gap between adjacent electrodes, and eight connecting rods 314 are connected to the five inner electrodes and span the gap between adjacent electrodes. Each connecting rod 314 can be adapted according to the circumferential length of each electrode, so that electrodes with larger outer circumferential lengths receive more connecting rod support, and electrodes with smaller inner circumferential lengths receive correspondingly less connecting rod support. This not only saves material but also provides a balanced radial constraint force during overall injection molding, preventing electrode deformation.

[0108] Example 3

[0109] An embodiment of the present invention provides an adsorption unit. Referring to Figures 9-14, the adsorption unit 1 includes a first electrode assembly 11 and a second electrode assembly 12. The first electrode assembly 11 is an integrally formed structure and includes a first electrode connector 112 and a first electrode 111. The second electrode assembly 12 is an integrally formed structure and includes a second electrode connector 122 and a second electrode 121. The first electrode assembly 11 includes a plurality of first electrodes 111 and a first electrode connector 112 disposed at the same end of the plurality of first electrodes 111 and used to connect the plurality of first electrodes 111 into one unit. The second electrode assembly 12 includes a plurality of second electrodes 121 and a second electrode connector 122 disposed at the same end of the plurality of second electrodes 121 and used to connect the plurality of second electrodes 121 into one unit.

[0110] It should be noted that the first electrode is connected to a negative high voltage or a positive high voltage, and the second electrode is grounded and forms an electric field with the first electrode for particulate matter adsorption. This electric field can be used alone or in combination with other electric fields or discharge units.

[0111] In one embodiment of the present invention, a first electrode connector 112 is disposed at one end of a first electrode 111 and connects a plurality of first electrodes 111 together to form an integral structure. A second electrode connector 122 is disposed at one end of a second electrode 121 and connects a plurality of second electrodes 121 together to form an integral structure. A first opening 113 is formed between the other ends of adjacent first electrodes 111, and a second opening 123 is formed between the other ends of adjacent second electrodes 121. A plurality of connected first electrodes 111 are inserted into the plurality of connected second electrodes 121 through the second opening 123, and a plurality of connected second electrodes 121 are inserted into the plurality of connected first electrodes 111 through the first opening 113, so that the first electrodes 111 and the second electrodes 123 are alternately arranged in sequence.

[0112] In one embodiment of the present invention, the first electrode 111 and the second electrode 112 are both hollow tubes, the first electrode 111 and the second electrode 112 are coaxially mounted, and the first electrode 111 and the second electrode 112 are alternately arranged in sequence from the axis to the outer periphery.

[0113] In one embodiment of the present invention, the first electrode connector 112 includes a first connecting rod 114, which is disposed at one end of a plurality of first electrodes 111 along the radial direction of the first electrode 111.

[0114] Specifically, the first electrode connector 112 includes a first connecting rod 114 and a first fixing member 115, with a plurality of first connecting rods 114 arranged circumferentially around the first fixing member 115 in a radial pattern.

[0115] In one embodiment of the present invention, the second electrode connector 122 includes a second connecting rod 124, which is disposed at one end of a plurality of second electrodes 121 along the radial direction of the second electrode 121.

[0116] Specifically, the second electrode connector 122 includes a second connecting rod 124 and a second fixing member 125, with a plurality of second connecting rods 124 arranged circumferentially around the first fixing member 125 in a radial pattern.

[0117] In one embodiment of the present invention, the adsorption unit 1 further includes a housing 13 and an insulating connector 14. The first electrode assembly 11 and the second electrode assembly 12 are disposed inside the housing. The insulating connector 14 provides an insulating connection between the first electrode 11 and the housing 13. The first connecting rod 114 and the insulating connector 14 are respectively provided with positioning mechanisms 16. The positioning mechanisms 16 of the first connecting rod 114 and the positioning mechanisms 16 of the insulating connector 14 are mutually positioned and installed. The insulating connector 14 is also provided with a first fixed end 141, which is connected to the housing 13. One end of the second connecting rod 124 extends out of the outermost second electrode 121 to form a conductive support frame 126. The conductive support frame 126 is configured to be connected to the housing 13 of the adsorption unit 1.

[0118] With this design, the second electrode assembly 12 is connected to the outer shell 13 through the conductive support frame 126, so that the second electrode 121 of the second electrode assembly 12 is grounded together with the outer shell 13, and the second electrode 121 and the outer shell 13 are also concentrically installed and fixed. The first electrode assembly 11 is insulatedly connected to the outer shell 13 through the insulating connector 14, so that the first electrode 111 and the outer shell 13 are concentrically installed and fixed. Since the second electrode 111, the second electrode 121 and the outer shell 13 are all concentrically installed and fixed, the distance between the first electrode 111 and the second electrode 121 is equal everywhere, which greatly reduces the error caused by manual assembly.

[0119] Specifically, the first connecting rod 114 and the insulating connector 14 are respectively provided with positioning mechanisms 16, which are screw holes. After positioning, they are installed and positioned by screws.

[0120] Specifically, the first connecting rod 114 and the insulating connector 14 are respectively provided with positioning mechanisms 16, which can be installed and positioned in a nested manner.

[0122] Example 4

[0123] This embodiment provides an electrode assembly. The electrode assembly in this embodiment can be the first electrode assembly or the second electrode assembly of Embodiment 1 or Embodiment 4. Only the differences are described, and the similarities are not repeated.

[0124] Referring to Figures 15 and 16, the electrode assembly 20 is an injection-molded integral structure and includes an electrode connector 22 (a first electrode connector or a second electrode connector) and an electrode 21 (a first electrode or a second electrode). The electrode assembly 20 includes a plurality of electrodes 21 and an electrode connector 22 disposed at the same end of the plurality of electrodes 21 and used to connect the plurality of electrodes 21 into one unit.

[0125] In one embodiment of the present invention, the electrode connector 22 includes a connecting rod 23 and a fixing member 24. The connecting rod 23 is disposed at one end of a plurality of electrodes 21 along the radial direction of the electrodes 21. The connecting rod 23 includes a groove 24 and includes a first surface 261 facing outward of the electrode assembly 20 and a second surface (not shown) facing inward of the electrode assembly 20. The first surface 261 is recessed into the second surface to form the groove 24.

[0126] This design allows the grooves to facilitate injection molding and prevent the electrode assembly from deforming due to material cooling during injection.

[0127] Specifically, groove 24 is a U-shaped groove.

[0128] In one embodiment of the present invention, the connecting rod 23 is provided with a groove 24 in the gap 25 between adjacent electrodes 21.

[0129] In one embodiment of the present invention, the distance between the inner surface of the groove 24 and the outer surface of the connecting rod 23 is the groove wall thickness d1, which is the same as the thickness d2 of the electrode 21. Since the groove 27 is disposed within the gap 25, and the four sides of the groove 24 are respectively two adjacent electrodes 21 and connecting rods 23, the groove wall of the groove 24 is equal everywhere. During injection molding, it can be ensured that the four sides and / or bottom of the groove 24 shrink uniformly and do not deform. Thus, the electrodes 21 and the connecting rods 23 shrink uniformly and do not deform, which facilitates the processing and production of the injection-molded electrode assembly 20.

[0130] Specifically, two opposing third surfaces 262 and fourth surfaces 263 are provided between the first surface 261 and the second surface. The distance from the inner surface 241 of the groove 24 to the third surface 262, the fourth surface 263, or the second surface is equal to the groove wall thickness d1, which is the same everywhere. The distance from the inner surface 241 of the groove 24 to the third surface 262 or the fourth surface 263 and the thickness d2 of the electrode 21 are equal to the surrounding groove wall thickness d1. The distance from the inner surface 241 of the groove 24 to the second surface is equal to the bottom groove wall thickness d1.

[0131] Example 5

[0132] This embodiment provides a discharge unit in which the free end of the discharge beam faces the air intake direction. In other words, the free end of the discharge beam faces the air intake unit, which can further improve the purification efficiency of the gas particulate matter purification device and make the purification of particulate matter in the gas more stable over a long period of time.

[0133] In one embodiment of the present invention, the discharge beam comprises n metal wires and / or conductive non-metal wires, wherein n is greater than or equal to 1,000; preferably, it comprises more than 5,000 metal wires and / or conductive non-metal wires; preferably, it comprises more than 10,000 metal wires and / or conductive non-metal wires; preferably, it comprises 10,000 to 200,000 metal wires and / or conductive non-metal wires; preferably, it comprises 10,000 to 80,000 metal wires and / or conductive non-metal wires. Typical, but not limiting, quantities of metal wires and / or conductive non-metal wires are 1,000, 2,000, 3,000, 4,000, 5,000, 6,000, 8,000, 10,000, 20,000, 50,000, 150,000, 200,000, 250,000, 300,000, 400,000, or 500,000.

[0134] Through this design, a discharge beam composed of thousands of metal wires and / or conductive non-metal wires is fixed on a support plate, resembling a brush. The discharge beam employs corona discharge, with the tip of each wire at its free end serving as a discharge point, significantly improving the discharge effect and effectively reducing ozone production to almost zero. In this invention, tests have shown that, under the same purification efficiency requirements, compared to purifying particulate matter in a gas using a single electrode rod or wire and an adsorption unit, the voltage required to be applied by the pre-discharge electrode assembly of this invention, when combined with the same adsorption unit, is far less than that required by a single electrode rod or wire. This results in advantages such as low energy consumption and low cost.

[0135] In one embodiment of the present invention, the diameter of the metal wire ranges from 0.1 to 100 μm; preferably, the diameter of the metal wire ranges from 5 to 100 μm; typical but non-limiting diameters of the metal wire are: 0.1 μm, 0.5 μm, 1 μm, 2 μm, 3 μm, 4 μm, 5 μm, 10 μm, 12 μm, 15 μm, 20 μm, 3 μm, 40 μm, 50 μm, 60 μm, 70 μm, 80 μm, 90 μm, or 100 μm. For example, the metal wire includes, but is not limited to, at least one of stainless steel fiber wire, titanium-chromium-aluminum alloy wire, titanium alloy wire, and nickel alloy wire; the metal wire includes stainless steel fiber wire, the single fiber diameter of the stainless steel fiber wire can range from 0.1 to 100 μm, the single fiber diameter of the stainless steel fiber wire can range from 5 to 100 μm, and the carbon content in the discharge material is 90-99.9%, typically but non-limiting carbon content is 90%, 93%, 96%, or 99%.

[0136] In one embodiment of the present invention, the diameter of the conductive non-metallic wire ranges from 0.1 to 100 μm; preferably, the diameter ranges from 5 to 100 μm; typical but non-limiting diameters of the conductive non-metallic wire are: 0.1 μm, 0.5 μm, 1 μm, 2 μm, 3 μm, 4 μm, 5 μm, 10 μm, 12 μm, 15 μm, 20 μm, 3 μm, 40 μm, 50 μm, 60 μm, 70 μm, 80 μm, 90 μm, or 100 μm. For example, the conductive non-metallic wire includes, but is not limited to, carbon fiber wire, the diameter of a single fiber of carbon fiber wire can range from 0.1 to 100 μm; the diameter of a single fiber of carbon fiber wire can range from 5 to 100 μm.

[0137] In this invention, a discharge beam, after being energized by an applied voltage, discharges to ionize the gas, charging the particulate matter within it. If an adsorption unit follows, the charged particles enter and are adsorbed, thus purifying the particulate matter. When the radial cross-sectional area of ​​the adsorption unit is small, the discharge unit can include a single discharge beam positioned at the center of the adsorption electric field. The area covered by this single beam is sufficient to radiate across the entire adsorption unit, ensuring the required adsorption and purification efficiency. When the radial cross-sectional area of ​​the adsorption unit is large, the discharge unit can include multiple discharge beams. These beams simultaneously perform corona discharge to enhance the particle charging efficiency and improve the adsorption effect of the subsequent adsorption electric field.

[0138] Example 6

[0139] This embodiment provides a material for an electrode assembly used in the integrally molded electrode assemblies of embodiments 1-5, such as a first electrode assembly and a second electrode assembly. The electrode assembly includes a substrate and conductive layers disposed on both sides of the substrate.

[0140] Optionally, the matrix material includes non-metallic materials, preferably resins. Resins can be engineering plastics such as polypropylene (PP), polyethylene terephthalate (PET), polyamide (PA), polyphenylene sulfide (PPS), acrylonitrile-butadiene-styrene copolymer (ABS), and polycarbonate / acrylonitrile-butadiene-styrene copolymer (PC / ABS) to meet the requirements for structural formability and insulation.

[0141] Optionally, the conductive layer material is attached to the surface of the substrate material. The conductive material may include one or more highly conductive materials selected from graphene, carbon nanotubes, conductive carbon materials, and metal nanoparticles (such as silver, copper, and nickel). Conductive carbon materials include carbon powder, carbon fiber, and carbon black.

[0142] Optionally, the coating thickness of the conductive layer is preferably 10-20 μm.

[0143] Optionally, the substrate is formed by injection molding, and the conductive layer is attached to the substrate surface by spraying. The conductive material may include a composite system of conductive fillers and binders, such as a conductive coating formed by dispersing one or more highly conductive materials, such as graphene, carbon nanotubes, conductive carbon black, and metal nanoparticles (such as silver, copper, and nickel), in a polymer carrier.

[0144] This structure provides mechanical support and an insulating framework through an injection-molded substrate, followed by a conductive layer sprayed onto the surface to form a double-sided conductive interface. This structure and process enable automated, large-scale production of electrode assemblies.

[0145] Optionally, the connection area in Embodiment 2 can be formed by masking the connection area during the spraying process. This part does not have a conductive layer, thus achieving the structure of Embodiment 2.

[0146] Optionally, the matrix material may also include a flame retardant, including a halogen-free flame retardant.

[0147] Example 7

[0148] This embodiment provides a material for an electrode assembly used in the integrally molded electrode assemblies of Embodiments 1-5, such as a first electrode assembly and a second electrode assembly. The electrode assembly uses a conductive plastic electrode material, which includes a mixture of a matrix material and conductive material particles. Preferably, the matrix material includes engineering plastics such as polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polyamide (PA), polyphenylene sulfide (PPS), acrylonitrile-butadiene-styrene copolymer (ABS), and polycarbonate / acrylonitrile-butadiene-styrene copolymer (PC / ABS). The conductive material includes graphene, carbon nanotubes, conductive carbon materials, and metal nanoparticles (such as silver, copper, and nickel). The conductive carbon material includes carbon powder, carbon fiber, and carbon black.

[0149] With this design, since the first electrode and the first electrode connector are made of the same conductive plastic (or the second electrode and the second electrode connector are made of the same conductive plastic), the material has a low melting point, which is beneficial for injection molding. The injection molding technology can ensure that the distance between multiple first electrodes is equal, reducing the error of manual assembly.

[0150] Optionally, the flame retardant includes a halogen-free flame retardant.

[0151] Optionally, the surface resistance or bulk resistance of the electrode material is less than 1 kΩ·m, and preferably, the surface resistance or bulk resistance of the electrode material is less than 100 Ω·m. The flame retardant added to the matrix material can effectively prevent combustion after ignition; for example, if flying insects or other impurities enter between adjacent electrodes, it can cause ignition.
