Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a gas particulate matter purification device, system, mask, and table. 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. The core electrostatic field is mostly composed of an adsorption plate and cathode wires installed within the adsorption plate. Therefore, the technology of the adsorption plate and cathode wires has become crucial for improving the particulate matter removal rate. Utility Model Content

[0103] Example 1

[0104] The first embodiment of this utility model provides a gas particulate matter purification device capable of efficiently adsorbing nanoscale particles, which include not only dust but also viruses and bacteria ranging from tens to hundreds of nanometers. (Refer to...) Figure 1 The gas particulate matter purification device 200 includes a pre-discharge electrode assembly 220 and an adsorption unit 230. Along the gas flow direction (in the direction of arrow A), the pre-discharge electrode assembly 220 is located in front of the adsorption unit 230 and is spaced apart from the adsorption unit 230. The pre-discharge electrode assembly 230 includes at least one discharge beam 221 connected to a DC high-voltage power supply.

[0105] With this design, the discharge beam 221 in the pre-discharge electrode group 220 discharges to charge the particulate matter in the gas, thereby improving the charge efficiency of the particulate matter. The charged particulate matter enters the adsorption unit 230 at the rear end for purification treatment. The adsorption unit adsorbs the charged particulate matter in the gas on the adsorption electrode. The particulate matter includes, but is not limited to, pollutants such as viruses, bacteria, and radiation-containing aerosols. After purification treatment, the particulate matter and aerosols containing viruses, bacteria, and radiation are removed from the gas, resulting in sterile, radiation-free, and virus-free clean gas, thus achieving the effect of gas purification.

[0106] In one embodiment of this utility model, reference is made to Figure 1 The adsorption unit 230 includes at least one grounded adsorption electrode 231 and at least one discharge electrode 232 for forming an adsorption electric field.

[0107] Through the design of this utility model, a voltage is applied between the adsorption electrode and the discharge electrode, making the adsorption performance of the adsorption unit more stable.

[0108] In one embodiment of this utility model, reference is made to Figure 1The adsorption electrode 231 end near the pre-discharge electrode group 220 extends out of the discharge electrode 232 end near the pre-discharge electrode group; or, the adsorption electrode 231 end near the pre-discharge electrode group 220 and the discharge electrode 232 end near the pre-discharge electrode group 220 are on the same plane perpendicular to the airflow direction, that is, the adsorption electrode 231 end near the pre-discharge electrode group 220 and the discharge electrode 232 end near the pre-discharge electrode group 220 are flush.

[0109] With this design, if the discharge electrode near the front discharge electrode group extends beyond the adsorption electrode, and the discharge beam is a negative high voltage, the discharge electrode can sense the high voltage of the discharge beam, thereby forming an induced voltage with a negative potential. An induced electric field will exist between the discharge electrode and the adsorption electrode. Therefore, by making the adsorption electrode near the front discharge electrode group extend or be flush with the discharge electrode 232 near the front discharge electrode group, it is possible to control whether there is an induced electric field between the discharge electrode and the adsorption electrode, or whether the induced electric field is very weak and insufficient to adversely affect the adsorption electric field. This makes it easy to adjust the distance between the adsorption unit and the discharge unit.

[0110] In one embodiment of this utility model, reference is made to Figure 1 The discharge electrode 232 includes a first discharge electrode end near the pre-discharge electrode group 220, and the adsorption electrode 231 includes a first adsorption electrode end near the pre-discharge electrode group 220, with the first adsorption electrode end located in front of the first discharge electrode end. That is, along the airflow direction, the gas first passes through the pre-discharge electrode group 220, then through the first adsorption electrode end, and finally through the first discharge electrode end. Alternatively, it can be understood that the end of the adsorption electrode 231 near the discharge beam 221 extends beyond the end of the discharge electrode 232.

[0111] Specifically, refer to Figure 1 The distance between the orthographic projection of the first end of the discharge electrode onto the adsorption electrode 231 and the first end of the adsorption electrode is less than or equal to 10 cm, and this distance is L2, where 0 < L2 ≤ 10 cm. Preferably, refer to... Figure 1 The distance between the orthogonal projection of the first end of the discharge electrode onto the adsorption electrode 231 and the first end of the adsorption electrode is less than or equal to 3 cm, and this distance is L2, where 0 < L2 ≤ 3 cm. Typical but non-limiting distances L2 are: 0.5 cm, 1 cm, 2 cm, 3 cm, 4 cm, 5 cm, 6 cm, 7 cm, 8 cm, 9 cm, or 10 cm.

[0112] In one embodiment of this utility model, the gas treatment device includes a power supply one and a power supply two. The two ends of power supply one are electrically connected to a discharge beam and an adsorption electrode, respectively. The two ends of power supply two are electrically connected to a discharge electrode and an adsorption electrode, respectively. The adsorption electrode is grounded. This can be understood as follows: the discharge beam is electrically connected to the negative terminal of power supply one; the adsorption electrode is electrically connected to the positive terminal of power supply one; the discharge electrode is electrically connected to the negative terminal of power supply two; and the adsorption electrode is also electrically connected to the positive terminal of power supply two, wherein the adsorption electrode is grounded.

[0113] In one embodiment of this utility model, reference is made to Figure 1 The adsorption electrode 231 and the discharge electrode 232 are both hollow tubes with different diameters. The discharge electrode 232 and the adsorption electrode 231 are coaxially mounted and arranged alternately from the center to the outer periphery. The vertical distance between the discharge electrode 232 and the adsorption electrode 231 is the same. A gas flow channel is formed between the discharge electrode 232 and the adsorption electrode 231 to allow gas to pass through for electric field treatment.

[0114] Specifically, refer to Figures 1-3 The cross-section of a hollow tube can be polygonal, as shown in the reference. Figure 4 The cross-section of a hollow tube can be circular.

[0115] For example, refer to Figure 4 The adsorption unit 100 includes a discharge electrode group and an adsorption electrode group for forming an electric field. In this embodiment, the discharge electrode group includes discharge electrode 11 and discharge electrode 12, and the adsorption electrode group includes adsorption electrode 21, adsorption electrode 22, and adsorption electrode 23. Both the discharge electrode group and the adsorption electrode group include cylinders of different diameters. Multiple cylinders are coaxially fitted together and staggered inside and outside, arranged sequentially from the inside to the outside as adsorption electrode 21, discharge electrode 11, adsorption electrode 22, discharge electrode 12, and adsorption electrode 23. The distance between adsorption electrode 21, discharge electrode 11, adsorption electrode 22, discharge electrode 12, and adsorption electrode 23 is the same. That is, adjacent cylinder walls are different electrodes, ensuring that the distance between each cylindrical electrode is consistent. A gas flow channel 31 is formed between adsorption electrode 21 and discharge electrode 11, a gas flow channel 32 is formed between discharge electrode 11 and adsorption electrode 22, a gas flow channel 33 is formed between adsorption electrode 22 and discharge electrode 12, and a gas flow channel 34 is formed between discharge electrode 12 and adsorption electrode 23.

[0116] Preferably, the polygon is a hexagon or a rectangle; more preferably, the hexagon is a regular hexagon, and the rectangle is a square.

[0117] Specifically, refer to Figures 1-3 Multiple discharge electrodes 232 are electrically connected as a single unit to serve as discharge electrodes, and multiple adsorption electrodes 231 are electrically connected as a single unit to serve as adsorption electrodes. For example, multiple first conductive rods 2321 are used to electrically connect multiple discharge electrodes 232 into a single unit, and multiple second conductive rods 2311 are used to electrically connect multiple adsorption electrodes 231 into a single unit. Both the first conductive rods 2321 and the second conductive rods 2311 are perpendicular to the axis of the cylinder. Both the first conductive rods 2321 and the second conductive rods 2311 are made of conductive material. One end of the first conductive rod 2321 is connected to the outer wall of the innermost discharge electrode, and the other end is connected to the inner wall of the outermost discharge electrode. One end of the second conductive rod 2311 is connected to the outer wall of the innermost adsorption electrode, and the other end is connected to the inner wall of the outermost adsorption electrode. The outermost adsorption electrode is grounded.

[0118] In one embodiment of this utility model, reference is made to Figure 1 In the adsorption unit 230, the smallest diameter hollow tube serves as the inner adsorption electrode. The gas particulate matter purification device 200 also includes a power supply D', which is located within the inner adsorption electrode. It is understood that the smallest diameter hollow tube in the adsorption unit can also serve as the inner discharge electrode, and the power supply D' can be located within the inner discharge electrode.

[0119] With this design, the power supply D' (e.g., a rechargeable battery) is cleverly placed inside the internal discharge electrode or the hollow tube of the internal discharge electrode, which reduces the size of the entire device, thereby reducing the amount of material used and saving costs.

[0120] In one embodiment of this utility model, reference is made to Figures 5-7 Both the adsorption electrode 15 and the discharge electrode 25 are flat plates. The discharge electrode 25 and the adsorption electrode 15 are arranged in parallel and staggered. The distance between the discharge electrode 25 and the adsorption electrode 15 is the same. A gas flow channel is formed between the discharge electrode 25 and the adsorption electrode 15 to allow gas to pass through for electric field treatment.

[0121] Specifically, such as Figure 5 As shown, the adsorption unit includes an adsorption electrode 10 and a discharge electrode 20. (As shown...) Figure 6 As shown, the adsorption electrode 10 has a first frame 14 and a plurality of parallel adsorption electrodes 15 connected to the first frame 14. The first frame 14 is a rectangular box, including a first upper cover plate, a first lower cover plate, a first left side plate, and a first right side plate. The two ends of the adsorption electrode 15 are respectively connected to the first upper cover plate and the first lower cover plate. The adsorption electrode 15 includes an upper end portion 151, a middle portion 152, and a lower end portion 153 connected in sequence. The widths of the upper end portion 151 and the lower end portion 153 are both smaller than the width of the middle portion 152 of the adsorption electrode. In the embodiment, the widths of the first upper cover plate and the first lower cover plate are the same as the width of the middle portion 152. Figure 7 As shown, the discharge electrode section 20 has a second frame 24 and a plurality of parallel discharge electrodes 25 connected to the second frame 24. The second frame is a rectangular box, including a second upper cover plate, a second lower cover plate, a second left side plate, and a second right side plate. The two ends of the discharge electrodes 25 are respectively connected to the second upper cover plate and the second lower cover plate. In the embodiment, the width of the second upper cover plate and the second lower cover plate is smaller than the width of the discharge electrodes 25.

[0122] Specifically, refer to Figures 5-7 At least a portion of the discharge electrode portion 20 is disposed within the adsorption electrode portion 10. Both the adsorption electrode 15 and the discharge electrode 25 are flat plates. Multiple adsorption electrodes 15 and multiple discharge electrodes 25 are arranged in parallel and staggered. The distance between the adsorption electrode 15 and the discharge electrode 25 is the same.

[0123] Specifically, refer to Figures 5-7There is a gap between the first frame 14 and the second frame 24, and the gap is the same as the distance between the adsorption electrode and the discharge electrode.

[0124] In one embodiment of this utility model, reference is made to Figure 1 In the adsorption unit 230, the outermost adsorption electrode 231 is the outer adsorption electrode, one end of which extends to form an extension portion 2312 and the front discharge electrode group 220 is disposed in the extension portion 2312.

[0125] Specifically, refer to Figure 1 For example, the adsorption electrode 231 and the discharge electrode 232 are both hollow tubes with different diameters. The discharge electrode 232 and the adsorption electrode 231 are coaxially mounted and arranged alternately from the center to the outer periphery. The hollow tube with the largest diameter in the adsorption unit 230 is the outer adsorption electrode. The end of the outer adsorption electrode near the front discharge electrode group 230 extends to form an extension 2312. The front discharge electrode group 220 is placed inside the extension 2312. That is, the extension 2312 is sleeved on the outside of the front discharge electrode group 220 and has a certain distance.

[0126] Specifically, refer to Figures 5-7 For example, both the adsorption electrode 15 and the discharge electrode 25 are flat plates, and the discharge electrode 25 and the adsorption electrode 15 are arranged in parallel and staggered. The outermost layer of the adsorption unit 230 is the external adsorption electrode, that is, the two sides of the outermost layer are the external adsorption electrodes. The two external adsorption electrodes extend to form extensions at one end near the front discharge electrode group 230, and the front discharge electrode group is placed between the extensions of the two external adsorption electrodes.

[0127] With this design, the external adsorption electrode can be used as the shell of the pre-discharge electrode assembly 220 and the adsorption unit 230, saving materials and simplifying the manufacturing process.

[0128] Preferably, refer to Figure 1 The vertical distance between the front discharge electrode assembly 220 and the extension 2312 is 5-150 mm. Preferably, referring to... Figure 1 The vertical distance between the front discharge electrode assembly 220 and the extension 2312 is 5-20 mm. Typical but non-limiting vertical distances are: 5 cm, 10 cm, 15 cm, 20 cm, 30 cm, 40 cm, 50 cm, 60 cm, 70 cm, 80 cm, 90 cm, 100 cm, 110 cm, 120 cm, 130 cm, 140 cm, or 150 cm.

[0129] In one embodiment of this utility model, reference is made to Figure 1 The inner wall of the extension 2312 is provided with an insulating layer (not shown in the figure) and the front discharge electrode group 220 is disposed in the insulating layer, and there is a distance between the insulating layer and the front discharge electrode group 220.

[0130] Specifically, refer to Figure 1 For example, the adsorption electrode 231 and the discharge electrode 232 are both hollow tubes with different diameters. The discharge electrode 232 and the adsorption electrode 231 are coaxially mounted and arranged alternately from the center to the outer periphery. The hollow tube with the largest diameter in the adsorption unit 230 is the outer adsorption electrode. The end of the outer adsorption electrode near the front discharge electrode group 230 extends to form an extension 2312. The insulating layer is at least partially sleeved on the inner wall of the extension 2312 of the outer adsorption electrode. The front discharge electrode group 220 is placed inside the insulating layer. That is, the insulating layer is sleeved on the outside of the front discharge electrode group 220 and has a certain distance.

[0131] Specifically, refer to Figures 5-7 For example, both the adsorption electrode 15 and the discharge electrode 25 are flat plates, and the discharge electrode 25 and the adsorption electrode 15 are arranged in parallel and staggered. The outermost layer of the adsorption unit 230 is the outer adsorption electrode, that is, the two sides of the outermost layer are the outer adsorption electrodes. The two outer adsorption electrodes extend to form extensions at one end near the front discharge electrode group 230, and the insulating layer is at least partially disposed on the inner wall of the extension 2312 of the two outer adsorption electrodes. The front discharge electrode group is placed between the two insulating layers.

[0132] With this design, the insulating layer can be made of plastic and connected to the inner wall of the extension 2312 of the outer adsorption electrode. By setting the insulating layer on the outside of the pre-discharge electrode group 220, the pre-discharge electrode group 220 discharges only to the adsorption unit 230, avoiding discharge to the surrounding area.

[0133] Preferably, refer to Figure 1 The vertical distance between the front discharge electrode assembly 220 and the insulating layer is 5-150 mm. Preferably, refer to... Figure 1 The vertical distance between the front discharge electrode assembly 220 and the insulating layer is 5-20 mm. Typical but non-limiting vertical distances are: 5 cm, 10 cm, 15 cm, 20 cm, 30 cm, 40 cm, 50 cm, 60 cm, 70 cm, 80 cm, 90 cm, 100 cm, 110 cm, 120 cm, 130 cm, 140 cm, or 150 cm.

[0134] It should be noted that the vertical distance between the pre-discharge electrode group and the extension refers to the vertical distance between the outermost discharge beam of the pre-discharge electrode group and the extension, and the distance between the insulating layer and the pre-discharge electrode group refers to the vertical distance between the outermost discharge beam of the pre-discharge electrode group and the insulating layer.

[0135] In one embodiment of this utility model, reference is made to Figure 1The distance between the discharge electrode 232 and the adsorption electrode 231 is less than 30 mm; preferably, the distance is less than 10 mm; preferably, the distance is 2.5-10 mm, or the distance is 3-6 mm. Typical but non-limiting distances are: 0.1 mm, 0.25 mm, 0.5 mm, 1 mm, 2 mm, 2.5 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 15 mm, 20 mm, 25 mm, or 30 mm.

[0136] It should be noted that the distance between adjacent discharge electrodes 232 and adsorption electrodes 231 is a vertical distance, which is the electrode spacing between discharge electrodes 232 and adsorption electrodes 231 in the adsorption unit.

[0137] In one embodiment of this utility model, reference is made to Figure 1 The voltage range between the discharge electrode 232 and the adsorption electrode 231 is -0.5kV to -12kV; preferably, the voltage range between the discharge electrode 232 and the adsorption electrode 231 is -1kV to -8kV; preferably, the voltage range between the discharge electrode 232 and the adsorption electrode 231 is -1kV to -3kV; preferably, the voltage range between the discharge electrode 232 and the adsorption electrode 231 is -0.5kV to -3kV. Typical but non-limiting induced voltages are: 0.1kV, 0.3kV, 0.5kV, 0.7kV, 1kV, 2kV, 3kV, 4kV, 5kV, 6kV, 7kV, 8kV, 9kV, 10kV, 11kV, or 12kV.

[0138] In one embodiment of this utility model, reference is made to Figure 1 When the distance between the discharge electrode 232 and the adsorption electrode 231 is less than 10 mm, the voltage range between the adsorption electrode 231 and the discharge electrode is -0.5 to -12 kV, or the voltage range between the adsorption electrode 231 and the discharge electrode is -0.5 to -1.2 kV.

[0139] It should be noted that when the vertical distance between adjacent discharge electrodes 232 and adsorption electrodes 231 is less than 10 mm, that is, when the inter-electrode spacing between discharge electrodes 232 and adsorption electrodes 231 in the adsorption unit is less than 10 mm, the voltage range between adsorption electrodes 231 and discharge electrodes is -0.5 to -12 kV, or the voltage range between adsorption electrodes 231 and discharge electrodes is -0.5 to -1.2 kV. The smaller the distance between discharge electrodes 232 and adsorption electrodes 231 in the adsorption unit, the lower the required voltage; the larger the distance, the higher the required voltage. However, the relationship between the distance and voltage between discharge electrodes 232 and adsorption electrodes 231 in the adsorption unit is non-linear. For example, if the distance between discharge electrodes 232 and adsorption electrodes 231 is 1 mm, the voltage can be -0.5 kV; if the distance is 10 mm, the voltage can be -12 kV.

[0140] In one embodiment of this utility model, reference is made to Figure 1 The ratio of the discharge area of ​​the pre-discharge electrode assembly 220 to the radial cross-sectional adsorption area of ​​the adsorption unit 230 is less than 0.9; preferably, the ratio is 0.5-0.9. Typical but non-limiting ratios are: 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, or 0.9.

[0141] It should be noted that:

[0142] If the pre-discharge electrode assembly has only one discharge beam, then the discharge area of ​​the pre-discharge electrode assembly is the area of ​​that discharge beam. This can be understood as the cross-sectional area of ​​the free end of the discharge beam perpendicular to the airflow direction. If the pre-discharge electrode assembly includes multiple discharge beams, then the discharge area of ​​the pre-discharge electrode assembly can be understood as the area enclosed by the outermost discharge beams, as shown in the reference diagram. Figure 8 For example, the pre-discharge electrode group 20 includes two discharge electrode groups 22 with different radii and coaxial arrangement. Each discharge group 22 includes multiple circumferentially arranged discharge beams 21. The discharge beams in the same circumferential direction are circular. The radius of the outermost discharge electrode group is R. Then the discharge area of ​​the pre-discharge electrode group is πR. 2 .

[0143] The radial cross-sectional adsorption area of ​​the adsorption unit is the cross-sectional area of ​​the adsorption unit perpendicular to the airflow direction. Since the airflow passes through the pre-discharge electrode assembly before passing through the adsorption unit, it can be understood as the area of ​​the end of the adsorption unit facing the pre-discharge electrode assembly. For example, if the adsorption electrode and discharge electrode in the adsorption unit are both hollow tubes of different diameters, and the discharge electrode and adsorption electrode are coaxially mounted and arranged alternately from the axis outwards, the radial cross-sectional adsorption area of ​​the adsorption unit is the cross-sectional area of ​​the hollow tube with the largest diameter. If the hollow tube is circular, the cross-sectional area is the area of ​​the circle with the largest diameter; if the hollow tube is hexagonal, the cross-sectional area is the area of ​​the outermost hexagon. For example, if both the adsorption electrode and discharge electrode are flat plates, and the discharge electrode and adsorption electrode are arranged parallel and alternately, the radial cross-sectional adsorption area of ​​the adsorption unit is the area of ​​the rectangle enclosed by the outermost adsorption electrode.

[0144] In one embodiment of this utility model, reference is made to Figure 1 The voltage of the discharge beam 221 is -3kV to -60kV, and the radial cross-sectional adsorption area of ​​the adsorption unit is 0.001m². 2 -0.5m 2 The explanation of the radial cross-sectional adsorption area of ​​the adsorption unit can be found in the description above.

[0145] Optionally, the radial cross-sectional adsorption area of ​​a typical but non-limiting adsorption unit is 0.001 m². 2 0.005m 2 0.01m 2 0.05m 2 0.04m 2 0.08m 2 0.1m 2 0.2m 2 0.3m 2 0.4m 2 or 0.5m 2 .

[0146] It should be noted that the smaller the radial cross-sectional adsorption area of ​​the adsorption unit, the lower the voltage of the discharge beam required, and the closer the discharge beam is to the adsorption unit. Conversely, the larger the radial cross-sectional adsorption area of ​​the adsorption unit, the higher the voltage of the discharge beam required, and the farther the discharge beam is from the adsorption unit. However, the relationship between the radial cross-sectional adsorption area of ​​the adsorption unit and the voltage of the discharge beam is non-linear.

[0147] In one embodiment of this utility model, reference is made to Figure 1There is a direct proportional relationship between the vertical distance L1 from the free end of the discharge beam 221 to the first end of the adsorption electrode of the adsorption unit 230 and the vertical distance L3 from the discharge beam 221 to the inner wall of the outermost adsorption electrode: L1 = (0.7~3) × L3. Preferably, L1 = (0.7~2) × L3. Typical but non-limiting relationships between L1 and L3 are: L1 = 0.7 × L3, L1 = 0.8 × L3, L1 = 0.9 × L3, L1 = 1 × L3, L1 = 1.5 × L3, L1 = 2 × L3, L1 = 2.5 × L3, or L1 = 3 × L3.

[0148] Specifically, for example, the vertical distance L1 from the free end of the discharge beam 221 to the first end of the adsorption electrode of the adsorption unit 230 can range from 2cm to 8cm.

[0149] In one embodiment of this utility model, reference is made to Figure 1 The flow velocity of the gas undergoing electric field treatment in the gas particulate matter purification device 200 ranges from 0.2 to 2.0 m / s. Preferably, the flow velocity of the gas undergoing electric field treatment in the gas particulate matter purification device 200 ranges from 1 m / s.

[0150] In one embodiment of this utility model, reference is made to Figure 1 The voltage range of the discharge beam 221 is -3kV to -60kV;

[0151] In one embodiment of this utility model, the thickness of the discharge electrode and / or adsorption electrode is 0.01-5 mm; preferably, the thickness is 1.0-5 mm; preferably, the thickness is 0.2-3 mm.

[0152] In one embodiment of this utility model, reference is made to Figure 1 The length of the gas flow channel is 50-200mm.

[0153] In one embodiment of this utility model, reference is made to Figure 1 The discharge electrode 232 and / or adsorption electrode 231 are made of metallic or non-metallic conductive materials. The non-metallic conductive materials include at least one of graphite, graphene, carbon nanotubes, C60, carbon fibers, conductive carbon black, amorphous carbon, and ion-conducting ceramics, or a synthetic material containing at least one of graphite, graphene, carbon nanotubes, C60, carbon fiber filaments, conductive carbon black, amorphous carbon, and ion-conducting ceramics; the metallic materials include stainless steel.

[0154] In one embodiment of this utility model, reference is made to Figure 1The gas particulate matter purification device 200 includes a gas inlet 2111 and a gas outlet 2121. A pre-discharge electrode assembly 220 is located near the gas inlet 2111, and an adsorption unit 230 is located near the gas outlet 2121. Metal meshes are provided at both the gas inlet 2111 and the gas outlet 2121. These meshes are used to shield electromagnetic signals, effectively preventing electromagnetic waves from being exposed, and allowing gas to pass through them.

[0155] In one embodiment of the present invention, the gas particulate matter purification device further includes a power source, and the adsorption unit includes a first end close to the pre-discharge electrode group and a second end far from the pre-discharge electrode group, with the power source located behind the second end of the adsorption unit.

[0156] In one embodiment of the present invention, the gas particulate matter purification device further includes an air equalization unit, and the gas passes through the air equalization unit, the pre-discharge electrode group and the adsorption unit in sequence along the gas flow direction.

[0157] In the gas particulate matter purification system provided in this embodiment, gas passing through the gas particulate matter purification device can remove micron-sized and nano-sized particles. The removal effect of particles larger than 100 nanometers can reach more than 99.99%. After the gas passes through the gas particulate matter purification device, it can obtain sterile, radiation-free and virus-free clean gas.

[0158] Example 2

[0159] like Figure 1 As shown, this embodiment provides a pre-discharge electrode assembly, which can be used in the gas particulate matter purification device in Embodiment 1. The parts identical to those in Embodiment 1 will not be repeated; only the differences will be described. The pre-discharge electrode assembly 220 includes at least one discharge beam 221. The discharge beam 221 includes multiple metal wires and / or conductive non-metal wires (discharge materials). One end of each metal wire and / or non-metal wire is fixed together to form a fixed end, and the other end is a free end. The multiple metal wires and / or non-metal wires at the free end are dispersed. The pre-discharge electrode assembly 220 also includes a support plate 222. The fixed end of the discharge beam 221 is fixed to the support plate 222, which is made of a conductive material. The discharge beam of the pre-discharge electrode group is used for discharge after a voltage is applied. The discharge beam 221 is fixed on the conductive support plate 222. With this design, one or more discharge beams are fixed, and when the support plate is electrically connected to one pole of the DC power supply, the discharge beam 221 is also connected to the DC power supply. In the case of multiple discharge beams, multiple discharge beams can be connected to one power supply at the same time. The structure is simple and convenient.

[0160] In one embodiment of this utility model, reference is made to Figure 1The discharge beam 221 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.

[0161] Through this design, a discharge beam composed of thousands of metal wires and / or conductive non-metal wires is fixed on the 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 by the pre-discharge electrode assembly in this invention, 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.

[0162] In one embodiment of this utility model, 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 range of the stainless steel fiber wire can be 5-100 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%.

[0163] In one embodiment of this utility model, 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.

[0164] In this invention, the discharge beam of the pre-discharge electrode assembly is subjected to voltage for discharge, ionizing the gas and charging the particulate matter in it. If there is an adsorption unit following, the charged particulate matter enters the adsorption unit and is adsorbed, thereby purifying the particulate matter. When the radial cross-sectional area of ​​the adsorption unit is small, the pre-discharge electrode assembly can include a single discharge beam positioned at the center of the adsorption electric field. The area covered by the discharge 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 pre-discharge electrode assembly can include multiple discharge beams. Multiple discharge beams simultaneously perform corona discharge to enhance the particle charging efficiency and improve the adsorption effect of the subsequent adsorption electric field.

[0165] In this invention, the corona discharge on the front discharge electrode assembly uses a DC negative high voltage with a voltage range of -3kV to -60kV. Further, the voltage range is -3kV to -25kV, -4kV to -15kV, -8kV to -20kV, -10kV to -20kV, -15kV to -18kV, or -10kV to -23kV. Typical but non-limiting voltages are -3kV, -3.5kV, -4kV, -5kV, -6kV, and -7kV. -8kV, -9kV, -10kV, -12kV, -13kV, -14kV, -15kV, -16kV, -17kV, -18kV, -19kV, -20kV, -21kV, 22kV, -23kV, -24kV, -25kV, -26kV, 27kV, -28kV, -29kV, 30kV, -35kV, -40kV, -45kV, -50kV, -55kV, or -60kV.

[0166] In one embodiment of this utility model, a pre-discharge electrode assembly and an adsorption unit constitute a gas particulate matter purification device for adsorbing particulate matter in gas to obtain sterile, radiation-free, and virus-free clean gas. The pre-discharge electrode assembly is located in front of the adsorption unit along the gas flow direction, with a distance between them. The discharge beam in the pre-discharge electrode assembly charges at least a portion of the particulate matter in the flowing gas, and the gas with at least a portion of the charged particulate matter enters the adsorption unit for electrostatic particulate removal treatment.

[0167] The pre-discharge electrode assembly provided in this embodiment can further improve discharge efficiency, thereby improving the removal efficiency of downstream particulate matter. When applied to a gas particulate matter purification system, it can further improve the purification efficiency of micron-sized and nano-sized particles.

[0168] Example 3

[0169] like Figure 8 As shown, this embodiment provides another pre-discharge electrode assembly 20, which can be used in the gas particulate matter purification device of Embodiment 1. The parts that are the same as those in Embodiment 2 will not be repeated; only the differences will be described. The pre-discharge electrode assembly 20 includes at least one discharge electrode group 22. The discharge group 22 includes multiple circumferentially arranged discharge beams 21. It is understood that the discharge beams 41 in the discharge electrode group 22 are circularly distributed. The pre-discharge electrode assembly 20 also includes a support plate 23, which is circular, and the fixed ends of the discharge beams 21 are disposed on the support plate 23. Multiple discharge electrodes 22 are connected by a DC high-voltage power supply to achieve DC high-voltage power supply connection between the pre-discharge electrode assembly 20 and the DC high-voltage power supply.

[0170] Continue to refer to Figure 8 The pre-discharge electrode group 20 includes multiple discharge electrode groups 22 with different radii and coaxial arrangement. For example, in this embodiment, the pre-discharge electrode group 20 includes two discharge electrode groups 22. The discharge beams 41 in each discharge electrode group 22 are distributed in a circle. The radii of the circles in the two discharge electrode groups 22 are different, but the center positions are the same.

[0171] In this embodiment, as Figure 9 As shown, the discharge beam 21 is arranged along the axial direction BB' of the discharge electrode group 22, that is, the extension line of the discharge beam is parallel to the axis. In other words, in this embodiment, the discharge beam 21 is arranged along the airflow direction.

[0172] In this invention, the discharge electrode group includes multiple discharge beams, which improves the corona discharge efficiency compared to a single discharge beam. At the same time, the multiple discharge beams are arranged circumferentially, resulting in more uniform discharge and improving the efficiency of particle removal at the downstream end.

[0173] Example 4

[0174] This embodiment provides another front discharge electrode assembly, which differs from embodiment 3 in that the discharge beam setting direction in the front discharge electrode assembly is as described in embodiment 3.

[0175] In this embodiment, the front discharge electrode group 20' includes a discharge electrode group 22', and the discharge group 22' includes multiple circumferentially arranged discharge beams 21', with the discharge beams 21' in the discharge electrode group 22' being circularly distributed.

[0176] Reference Figure 10 In this embodiment, the extension line of the discharge beam 21 forms an angle α with the axis BB' of the discharge electrode group. Preferably, the angle α is 10-85°.

[0177] In this invention, the discharge beam in the circumferentially arranged discharge electrode group is inclined to the axial discharge, which can further improve the discharge efficiency, thereby improving the efficiency of particle removal at the downstream end.

[0178] Example 5

[0179] This embodiment provides a metal mesh device for adsorbing and purifying large particulate matter, including micron-sized particles, in gases. (Refer to...) Figure 11 and Figure 12 (Hollow arrows indicate the direction of gas flow). The metal mesh device 400 includes a metal mesh pre-discharge electrode group 410 and a first metal mesh adsorption unit 420. The metal mesh pre-discharge electrode group 410 includes at least one discharge beam 411 connected to a DC high-voltage power supply. The first metal mesh adsorption unit 420 includes a first multi-layer metal mesh 421 stacked together and grounded. Along the gas flow direction, the first metal mesh adsorption unit 420 is located in front of the metal mesh pre-discharge electrode group 410 and has a distance between it and the metal mesh pre-discharge electrode group 410 (see reference). Figure 11 ), or the first metal mesh adsorption unit 420 is located behind the metal mesh front electrode group 410 and has a distance between it and the metal mesh front electrode group 410 (see reference). Figure 12 The discharge beam 411 of the metal mesh pre-discharge electrode group 410 is directed toward the first metal mesh adsorption unit 420. The discharge beam 411 and the first multilayer metal mesh 421 form an electric field. The gas undergoes electric field purification treatment through the electric field between the first metal mesh adsorption unit 420 and the metal mesh pre-discharge electrode group 410, removing micron-sized particles, i.e. large particles, from the gas. The removal efficiency is at least 70-80%.

[0187] In one embodiment of this utility model, reference is made to Figure 15 The metal mesh device 400 further includes a second metal mesh adsorption unit 430, which includes a second multilayer metal mesh 431. Along the gas flow direction, the first metal mesh adsorption unit 420 is located on one side of the metal mesh pre-electrode assembly 410, and the second metal mesh adsorption unit 430 is located on the other side of the metal mesh pre-electrode assembly 410. (Refer to...) Figure 5 (The hollow arrow indicates the direction of gas flow), in Figure 11A second metal mesh adsorption unit 430 is provided behind the metal mesh device, that is, the second metal mesh adsorption unit 430 is located behind the metal mesh front electrode assembly 410. The first metal mesh adsorption unit 420 is located in front of the metal mesh front electrode assembly 410. The metal mesh front electrode assembly 410 is disposed between the two metal mesh adsorption units (the first metal adsorption unit 420 and the second metal adsorption unit 430) and is respectively between the first metal adsorption unit 420 and the second metal adsorption unit 430. With a distance between them, the discharge beam 411 is directed toward the first multilayer metal mesh 421. The discharge beam 411 and the first multilayer metal mesh 421 form an electric field. The gas undergoes electric field purification treatment through the electric field between the first metal adsorption unit 420 and the metal mesh front discharge electrode group 410, removing most of the micron-sized particles, i.e., large particles, from the gas. After the gas with large particles removed and purified by the electric field enters the second multilayer metal mesh 431 of the second metal adsorption unit 430, the particles in the gas can be further adsorbed by the physical adsorption of the multilayer metal mesh, thereby improving the removal efficiency.

[0188] In one embodiment of this utility model, such as Figure 15 In the process, the second multilayer metal mesh 431 of the second metal mesh adsorption unit 430 is electrically connected to the positive electrode of the DC high voltage power supply.

[0189] In one embodiment of this utility model, the second metal adsorption unit 430 may also be de-energized. In this case, when gas flows through the second metal adsorption unit 430, the physical adsorption of particulate matter in the gas is achieved by using a multi-layer metal mesh.

The metal mesh front discharge electrode group 410 is disposed between the two metal mesh adsorption units (the first metal adsorption unit 420 and the second metal adsorption unit 430) and has a distance between it and the first metal adsorption unit 420 and the second metal adsorption unit 430 respectively. The discharge beam 411 is directed toward the first multilayer metal mesh 421, and an electric field is formed between the discharge beam 411 and the first multilayer metal mesh 421. The gas first enters the second metal adsorption unit 430, and through the physical adsorption of the second multilayer metal mesh 431, some large particles in the gas can be adsorbed. At the same time, it plays a role in equalizing the gas flow, allowing the gas to pass more evenly through the electric field between the first metal adsorption unit 420 and the front discharge electrode group 410 of the metal mesh. In this electric field, the gas is further purified, removing micron-sized particles from the gas, improving the ability to adsorb particles, and improving the removal efficiency.

[0191] In one embodiment of this utility model, reference is made to Figure 17 (The hollow arrow indicates the direction of gas flow), in Figure 5 Based on the provided metal mesh device, the first metal adsorption unit 420 includes a non-metallic rod 422, and the first multilayer metal mesh 421 includes a first end face facing the front discharge electrode group 410 of the metal mesh and a second end face facing away from the front discharge electrode group 410 of the metal mesh. The first non-metallic rod 422 is disposed on the first end face of the first multilayer metal mesh 421. The first non-metallic rod 422 induces the high voltage of the discharge beam 411 and forms an induced electric field with the first multilayer metal mesh 421. Under the combined adsorption effect of the induced electric field, the electric field formed between the first multilayer metal mesh 421 and the discharge beam 411, and the second metal adsorption unit 430, large particles in the gas are effectively removed, and the removal efficiency reaches more than 80%.

[0192] It should be noted that, in this utility model, the distance between the first metal mesh adsorption unit 420 and the metal mesh front discharge electrode group 410 refers to the vertical distance from the free end of the discharge beam 411 on the metal mesh front discharge electrode group 410 to the first multilayer metal mesh 421.
