Description

Technical Field

[0001] This invention relates to the field of technology, specifically to a gas particulate matter purification device, system, mask system, 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. Summary of the Invention

[0070] The beneficial effects of this invention are as follows: The gas particulate matter purification device provided by this invention includes three electrodes: a discharge beam, an induction electrode, and an adsorption electrode. The two ends of the power supply are electrically connected to the discharge beam and the adsorption electrode, respectively. The discharge beam is a negative high voltage, and the adsorption electrode is simultaneously grounded. The induction electrode does not need to be energized, but it can sense the negative high voltage of the discharge beam to form a negative potential induced voltage. The negative high voltage induction electrode and the adsorption electrode form an induced electric field. Its main advantages are as follows: First, the electric field formed by the induction electrode and the adsorption electrode through the high voltage of the discharge beam is less prone to arcing. In this case, the accuracy requirement for the electrode spacing is lower, which can reduce manufacturing precision and costs during large-scale production. Second, since the electric field between the induction electrode and the adsorption electrode is induced, meaning that the induction electrode and the adsorption electrode are not directly electrically connected to the two ends of the power supply, even if foreign objects (such as water, flying insects, excessive dust, etc.) are present between the induction electrode and the adsorption electrode during the adsorption and dust removal process, they will not affect the power supply or burn it out. The design of the discharge beam, induction electrode, and adsorption electrode in this invention enhances the anti-pollution capability of the gas particulate matter purification device. Meanwhile, in the presence of foreign objects, the adsorption capacity between the sensing electrode and the adsorption electrode is reduced or even disappears; when the foreign object obstacle is removed, such as when water vapor evaporates and the flying insect is removed, the adsorption capacity between the sensing electrode and the adsorption electrode returns to normal, which makes the device adaptive and self-repairing.

[0071] In addition, the gas particulate matter purification device provided by the present invention can efficiently adsorb nano-sized particles, which include not only dust, but also viruses and bacteria ranging from tens to hundreds of nanometers.

[0072] In the gas particulate matter purification system provided by the present invention, 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. Attached Figure Description

[0100] Example 1

[0101] The first embodiment of the present invention 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. (See reference...) Figure 1 The gas particulate matter purification device 200 includes a discharge unit 220 and an adsorption unit 230. Along the gas flow direction (in the direction of arrow A), the discharge unit 220 is located in front of the adsorption unit 230 and there is a distance between them. The discharge unit 230 includes at least one discharge beam 221 connected to a DC high voltage power supply.

[0102] With this design, the discharge beam 221 in the discharge unit 220 discharges to charge the particulate matter in the gas, improving the charge efficiency of the particulate matter. The charged particulate matter enters the adsorption unit 230 at the back 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 purifying the gas.

[0103] In one embodiment of the present invention, reference is made to Figure 1 The adsorption unit 230 includes at least one grounded adsorption electrode 231 and at least one induction electrode 232 that does not require power. The induction electrode 232 senses the high voltage of the discharge beam 221 and forms an induced electric field with the adsorption electrode 232.

[0104] It should be noted that the induction electrode does not need to be energized, including the induction electrode not being grounded and not being electrically connected to a DC high-voltage power supply.

[0105] In existing technologies, electrostatic adsorption involves two electrodes, one grounded and the other connected to a high-voltage power supply, or the other connected to the positive and negative terminals of the power supply. Existing electrostatic adsorption devices have the following drawbacks: First, the electrode spacing requires high precision during manufacturing, as a fixed spacing at any point on the electrodes is necessary to prevent arcing, which affects dust removal efficiency. Second, during dust removal, excessive contaminants adsorbed onto one electrode can alter the discharge distance at that point, potentially causing a short circuit or partial short circuit, and ultimately damaging the power supply.

[0106] In this invention, electrostatic adsorption comprises three electrodes: a discharge beam, an induction electrode, and an adsorption electrode. The two ends of the power supply are electrically connected to the discharge beam and the adsorption electrode, respectively. The discharge beam is a negative high voltage, and the adsorption electrode is simultaneously grounded. The induction electrode does not need to be energized, but it can sense the negative high voltage of the discharge beam to form a negatively induced voltage. The negatively induced high voltage induction electrode and the adsorption electrode form an induced electric field, which has the following advantages:

[0107] First, the electric field formed between the induction electrode and the adsorption electrode by the high voltage of the induction discharge beam makes it less likely to cause arcing. Under such circumstances, the accuracy requirement for the electrode spacing between the two electrodes is lower, which can reduce manufacturing precision and costs during mass production.

[0108] Secondly, since the electric field between the induction electrode and the adsorption electrode is induced, meaning that the induction electrode and the adsorption electrode are not directly connected to the two ends of the power supply, even if foreign objects (such as water, flying insects, excessive dust, etc.) are present between the induction electrode and the adsorption electrode during the adsorption and dust removal process, it will not affect the power supply and burn it out. The design of the discharge beam, induction electrode, and adsorption electrode in this invention can enhance the anti-pollution capability of the gas particulate matter purification device. Simultaneously, in the presence of foreign objects, the adsorption capacity between the induction electrode and the adsorption electrode decreases or even disappears; when the foreign object obstacle is removed, such as when water vapor evaporates or flying insects are removed, the adsorption capacity between the induction electrode and the adsorption electrode returns to normal. This gives the device self-adaptability and self-repair capability.

[0109] Furthermore, the discharge unit and adsorption unit can generate ion wind. When the ion wind is sufficient to propel the gas for purification, there is no need for additional wind-generating equipment such as fans. This not only reduces equipment investment but also saves the electricity required for future fan use. In other special cases where the ion wind is insufficient to propel the gas for purification, additional equipment such as fans can be added.

[0110] In one embodiment of the present invention, reference is made to Figure 1 The discharge beam 221 and the induction electrode 232 form an induction electric field before and after, so that the induction electrode 232 has an induced voltage. The induction electrode 232 with the induced voltage forms an induction electric field with the adsorption electrode 231.

[0111] With this design, the adsorption unit 230 includes at least one adsorption electrode 231 and at least one induction electrode 232. One pole of the DC power supply is connected to the discharge beam 221, and the other pole is connected to the adsorption electrode. The discharge beam 221 at the front end and the induction electrode 232 at the rear end, which does not require power, induce a current. The induction electrode 232 induces the high voltage of the discharge beam 221 and forms an induced electric field with the adsorption electrode 231. The induction electrode 232 is neither connected to a power source nor grounded. The induction electrode 232 becomes charged by inducing the high voltage of the discharge beam 221 and forms an adsorption electric field with the adsorption electrode 231. A gas flow channel is formed between the induction electrode 232 and the adsorption electrode 231 to allow gas to pass through for electric field treatment. The discharge beam 221 charges the particulate matter, thereby adsorbing it onto the adsorption electrode 231.

[0112] In one embodiment of the present invention, reference is made to Figure 1 The induction electrode 232 includes a first induction electrode end near the discharge unit 220, and the adsorption electrode 231 includes a first adsorption electrode end near the discharge unit 220. The first induction electrode end is located in front of the first adsorption electrode end. That is, along the airflow direction, the air first passes through the discharge unit 220, then through the first induction electrode end of the induction electrode 232, and then through the first adsorption electrode end of the adsorption electrode 231. It can also be understood that the end of the induction electrode 232 near the discharge beam 221 extends out of the end of the adsorption electrode 231.

[0113] With this design, the sensing electrode 232 can better sense the high voltage of the discharge beam 221 and form an induced electric field with the adsorption electrode 231.

[0114] Specifically, refer to Figure 1 The distance between the orthographic projection of the first end of the adsorption electrode onto the induction electrode 232 and the first end of the induction electrode is less than or equal to 10 cm, where L2 is the distance, and 0 < L2 ≤ 10 cm. Preferably, refer to... Figure 1 The distance between the orthographic projection of the first end of the adsorption electrode onto the induction electrode 232 and the first end of the induction 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.

[0115] In one embodiment of the present invention, reference is made to Figure 1 The adsorption electrode 231 and the induction electrode 232 are both hollow tubes with different diameters. The induction 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 induction electrode 232 and the adsorption electrode 231 is the same. A gas flow channel is formed between the induction electrode 232 and the adsorption electrode 231 to allow gas to pass through for induction electric field processing.

[0116] 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.

[0117] For example, refer to Figure 4 The adsorption unit 100 includes an induction electrode group and an adsorption electrode group for forming an electric field. In this embodiment, the induction electrode group includes induction electrode 11 and induction electrode 12, and the adsorption electrode group includes adsorption electrode 21, adsorption electrode 22, and adsorption electrode 23. Both the induction electrode group and the adsorption electrode group include cylinders of different diameters. Multiple cylinders are coaxially mounted and staggered inside and outside, arranged sequentially from the inside to the outside as adsorption electrode 21, induction electrode 11, adsorption electrode 22, induction electrode 12, and adsorption electrode 23. The distance between adsorption electrode 21, induction electrode 11, adsorption electrode 22, induction 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 induction electrode 11, a gas flow channel 32 is formed between induction electrode 11 and adsorption electrode 22, a gas flow channel 33 is formed between adsorption electrode 22 and induction electrode 12, and a gas flow channel 34 is formed between induction electrode 12 and adsorption electrode 23.

[0118] Preferably, the polygon is a hexagon or a rectangle; more preferably, the hexagon is a regular hexagon, and the rectangle is a square.

[0119] Specifically, refer to Figures 1-3 Multiple induction electrodes 232 are electrically connected to form a single induction electrode, and multiple adsorption electrodes 231 are electrically connected to form a single adsorption electrode. There is no conductive connection between the induction electrodes 232 and the adsorption electrodes 231, but an induced electric field is formed between them. For example, multiple first conductive rods 2321 are used to electrically connect the multiple induction electrodes 232 to a single unit, and multiple second conductive rods 2311 are used to electrically connect the multiple adsorption electrodes 231 to a single unit. Both the first and second conductive rods 2321 are perpendicular to the axis of the cylinder. Both the first and second conductive rods 2321 are made of conductive material. One end of the first conductive rod 2321 is connected to the outer wall of the innermost induction electrode, and the other end is connected to the inner wall of the outermost induction 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.

[0120] In one embodiment of the present invention, reference is made to Figure 1 In the adsorption unit 230, the smallest diameter hollow tube serves as the inner induction electrode. The gas particulate matter purification device 200 also includes a power supply D', which is located within the inner induction electrode. It is understood that the smallest diameter hollow tube in the adsorption unit can also be the inner adsorption electrode, and the power supply D' can be located within the inner adsorption electrode.

[0121] With this design, the power source D' (e.g., a rechargeable battery) is cleverly placed inside the hollow tube of the inner induction electrode or inner adsorption electrode, which reduces the size of the entire device, thereby reducing the amount of material used and saving costs.

[0122] In one embodiment of the present invention, reference is made to Figures 5-7 Both the adsorption electrode 15 and the induction electrode 25 are flat plates. The induction electrode 25 and the adsorption electrode 15 are arranged in parallel and staggered. The distance between the induction electrode 25 and the adsorption electrode 15 is the same. A gas flow channel is formed between the induction electrode 25 and the adsorption electrode 15 to allow gas to pass through for induction electric field processing.

[0123] Specifically, such as Figure 5 As shown, the adsorption unit includes an adsorption electrode 10 and a sensing electrode 20. For example... 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 sensing electrode portion 20 has a second frame 24 and a plurality of parallel sensing 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 sensing 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 sensing electrodes 25.

[0124] Specifically, refer to Figures 5-7 At least a portion of the sensing electrode 20 is disposed within the adsorption electrode 10. Both the adsorption electrode 15 and the sensing electrode 25 are flat plates. Multiple adsorption electrodes 15 and multiple sensing electrodes 25 are arranged in parallel and staggered. The distance between the adsorption electrode 15 and the sensing electrode 25 is the same.

[0125] Specifically, refer to Figures 5-7 There is a gap between the first frame 14 and the second frame 24, and the distance between the gap and the adsorption electrode 15 and the induction electrode 25 is the same.

[0126] In one embodiment of the present invention, reference is made to Figure 1 In the adsorption unit 230, the outermost adsorption electrode 231 is the outer adsorption electrode, and one end of the outer adsorption electrode extends to form an extension portion 2312, and the discharge unit 220 is disposed in the extension portion 2312.

[0127] Specifically, refer to Figure 1 For example, the adsorption electrode 231 and the sensing electrode 232 are both hollow tubes with different diameters. The sensing 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 close to the discharge unit 230 extends to form an extension 2312. The discharge unit 220 is placed inside the extension 2312. That is, the extension 2312 is sleeved on the outside of the discharge unit 220 and has a certain distance.

[0128] Specifically, refer to Figures 5-7 For example, both the adsorption electrode 15 and the sensing electrode 25 are flat plates. The sensing 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 discharge unit 230, and the discharge unit is placed between the extensions of the two outer adsorption electrodes.

[0129] With this design, the external adsorption electrode can be used as the shell of the discharge unit 220 and the adsorption unit 230, saving materials and simplifying the manufacturing process.

[0130] Preferably, refer to Figure 1 The vertical distance between the discharge unit 220 and the extension 2312 is 5-150 mm. Preferably, referring to... Figure 1 The vertical distance between the discharge unit 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.

[0131] In one embodiment of the present invention, 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 discharge unit 220 is disposed in the insulating layer, and there is a distance between the insulating layer and the discharge unit 220.

[0132] Specifically, refer to Figure 1For example, the adsorption electrode 231 and the induction electrode 232 are both hollow tubes with different diameters. The induction 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 discharge unit 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 discharge unit 220 is placed inside the insulating layer. That is, the insulating layer is sleeved on the outside of the discharge unit 220 and has a certain distance.

[0133] Specifically, refer to Figures 5-7 For example, both the adsorption electrode 15 and the induction electrode 25 are flat plates. The induction 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 discharge unit 230. The insulating layer is at least partially disposed on the inner wall of the extension 2312 of the two outer adsorption electrodes. The discharge unit is placed between the two insulating layers.

[0134] 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 discharge unit 220, the discharge unit 220 discharges only to the adsorption unit 230, avoiding discharge to the surrounding area.

[0135] Preferably, refer to Figure 1 The vertical distance between the discharge unit 220 and the insulating layer is 5-150 mm. Preferably, refer to... Figure 1 The vertical distance between the discharge unit 220 and the insulating layer is 5-20mm. Typical but non-limiting vertical distances are: 5cm, 10cm, 15cm, 20cm, 30cm, 40cm, 50cm, 60cm, 70cm, 80cm, 90cm, 100cm, 110cm, 120cm, 130cm, 140cm, or 150cm.

[0136] It should be noted that the vertical distance between the discharge unit and the extension refers to the vertical distance between the outermost discharge beam of the discharge unit and the extension, and the distance between the insulating layer and the discharge unit refers to the vertical distance between the outermost discharge beam of the discharge unit and the insulating layer.

[0137] In one embodiment of the present invention, reference is made to Figure 1The distance between the sensing 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.

[0138] It should be noted that the distance between adjacent sensing electrodes 232 and adsorption electrodes 231 is a vertical distance, which is the inter-electrode spacing between sensing electrodes 232 and adsorption electrodes 231 in the adsorption unit.

[0139] In one embodiment of the present invention, reference is made to Figure 1 The sensing voltage range of the sensing electrode 232 is -0.5kV to -12kV; preferably, the sensing voltage range of the sensing electrode 232 is -1kV to -8kV; preferably, the sensing voltage range of the sensing electrode 232 is -1kV to -3kV; preferably, the sensing voltage range of the sensing electrode 232 is -0.5kV to -3kV. Typical but non-limiting sensing voltages are: 0.1kV, 0.3kV, 0.5kV, 0.7kV, 1kV, 2kV, 3kV, 4kV, 5kV, 6kV, 7kV, 8kV, 9kV, 10kV, 11kV, or 12kV.

[0140] It should be noted that the induced voltage of the induction electrode 232 comes from the high voltage of the induced discharge beam 221.

[0141] In one embodiment of the present invention, reference is made to Figure 1 When the distance between the induction electrode 232 and the adsorption electrode 231 is less than 10 mm, the voltage range between the adsorption electrode 231 and the induction electrode is -0.5 to -12 kV, or the voltage range between the adsorption electrode 231 and the induction electrode is -0.5 to -1.2 kV.

[0142] It should be noted that when the vertical distance between adjacent induction electrodes 232 and adsorption electrodes 231 is less than 10mm, that is, when the inter-electrode spacing between induction electrodes 232 and adsorption electrodes 231 in the adsorption unit is less than 10mm, the voltage range between adsorption electrodes 231 and induction electrodes is -0.5 to -12kV, or the voltage range between adsorption electrodes 231 and induction electrodes is -0.5 to -1.2kV. The smaller the distance between induction 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 induction electrodes 232 and adsorption electrodes 231 in the adsorption unit is non-linear. For example, if the distance between induction electrodes 232 and adsorption electrodes 231 is 1mm, the voltage can be -0.5kV; if the distance is 10mm, the voltage can be -12kV.

[0143] In one embodiment of the present invention, reference is made to Figure 1 The ratio of the discharge area of ​​the discharge unit 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.

[0144] It should be noted that:

[0145] If the discharge unit has only one discharge beam, then the discharge area of ​​the discharge unit 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 discharge unit includes multiple discharge beams, then the discharge area of ​​the discharge unit can be understood as the area enclosed by the outermost ring of discharge beams, as shown in the reference section. Figure 8 For example, the discharge unit 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 discharge unit is πR. 2 .

[0146] 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 discharge unit first and then the adsorption unit, it can be understood as the area of ​​the end of the adsorption unit facing the discharge unit. For example, if the adsorption electrode and the induction electrode in the adsorption unit are both hollow tubes with different diameters, and the induction electrode and adsorption electrode are coaxially mounted and staggered from the center 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 the induction electrode are flat plates, and the induction electrode and adsorption electrode are arranged in parallel and staggered, the radial cross-sectional adsorption area of ​​the adsorption unit is the area of ​​the rectangle enclosed by the outermost adsorption electrode.

[0147] In one embodiment of the present invention, 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.

[0148] 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 .

[0149] 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.

[0150] In one embodiment of the present invention, 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 induction 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.

[0151] Specifically, for example, the vertical distance L1 from the free end of the discharge beam 221 to the first end of the inductive electrode of the adsorption unit 230 can range from 2cm to 8cm.

[0152] In one embodiment of the present invention, 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.

[0153] In one embodiment of the present invention, reference is made to Figure 1 The voltage range of the discharge beam 221 is -3kV to -60kV;

[0154] In one embodiment of the present invention, the thickness of the sensing electrode and / or the adsorption electrode is 0.01-5 mm; preferably, the thickness is 1.0-5 mm; preferably, the thickness is 0.2-3 mm.

[0155] In one embodiment of the present invention, reference is made to Figure 1 The length of the gas flow channel is 50-200mm.

[0156] In one embodiment of the present invention, reference is made to Figure 1 The induction 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-conductive 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-conductive ceramics; the metallic materials include stainless steel.

[0157] In one embodiment of the present invention, reference is made to Figure 1The gas particulate matter purification device 200 includes a gas inlet 2111 and a gas outlet 2121. A discharge unit 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.

[0158] 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 discharge unit and a second end away from the discharge unit, with the power source disposed behind the second end of the adsorption unit.

[0159] In one embodiment of the present invention, the gas particulate matter purification device further includes an air equalization unit, wherein the gas passes through the air equalization unit, the discharge unit and the adsorption unit in sequence along the gas flow direction.

[0160] 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.

[0161] Example 2

[0162] like Figure 1 As shown, this embodiment provides a discharge unit that 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 discharge unit 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 discharge unit 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 discharge unit is used for discharge after a voltage is applied. The discharge beam 221 is fixed to the conductive support plate 222. This design serves two purposes: first, it fixes one or more discharge beams; second, when the support plate is electrically connected to one pole of a 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 simultaneously, resulting in a simple and convenient structure.

[0163] In one embodiment of the present invention, 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.

[0164] Through this design, a discharge bundle composed of thousands of metal wires and / or conductive non-metal wires is fixed on a support plate, resembling a brush. The discharge bundle 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 discharge unit 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.

[0165] 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%.

[0166] 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.

[0167] In this invention, the discharge beam of the discharge unit is subjected to voltage for discharge, causing gas ionization and charging of particulate matter in the gas. If an adsorption unit follows, 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 discharge unit 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 throughout the entire adsorption unit, ensuring the required adsorption purification efficiency. When the radial cross-sectional area of ​​the adsorption unit is large, the discharge unit 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.

[0168] In this invention, the corona discharge on the discharge unit adopts 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, -7kV, and... 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.

[0169] In one embodiment of the present invention, a discharge unit and an adsorption unit constitute a gas particulate matter purification device for adsorbing particulate matter in a gas to obtain sterile, radiation-free, and virus-free clean gas. The discharge unit is located in front of the adsorption unit along the gas flow direction, and there is a distance between the discharge unit and the adsorption unit. The discharge beam in the discharge unit 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.

[0170] The discharge unit provided in this embodiment can further improve the 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.

[0171] Example 3

[0172] like Figure 8 As shown, this embodiment provides another discharge unit 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 different parts will be described. The discharge unit 20 includes at least one discharge electrode group 22, which 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 discharge unit 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 discharge unit 20 and the DC high-voltage power supply.

[0173] Continue to refer to Figure 8 The discharge unit 20 includes multiple discharge electrode groups 22 with different radii and coaxial arrangement. For example, in this embodiment, the discharge unit 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.

[0174] 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.

[0175] 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 particulate matter removal at the downstream end.

[0176] Example 4

[0177] This embodiment provides another discharge unit, which differs from embodiment 3 in that the discharge beam setting direction in the discharge unit is the same as that in embodiment 3.

[0178] In this embodiment, the discharge unit 20' includes a discharge electrode group 22', and the discharge electrode group 22' includes a plurality of circumferentially arranged discharge beams 21', and the discharge beams 21' in the discharge electrode group 22' are distributed in a circular shape.

[0179] 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°.

[0180] 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.

[0181] Example 5

[0182] 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 discharge unit 410 and a first metal mesh adsorption unit 420. The metal mesh discharge unit 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 discharge unit 410 and has a distance between it and the metal mesh discharge unit 410 (see reference). Figure 11 ), or the first metal mesh adsorption unit 420 is located behind the metal mesh discharge unit 410 and has a distance between it and the metal mesh discharge unit 410 (refer to...). Figure 12 The discharge beam 411 of the metal mesh discharge unit 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 passes through the electric field between the first metal mesh adsorption unit 420 and the metal mesh discharge unit 410 for electric field purification treatment, removing micron-sized particles, i.e. large particles, from the gas.

[0185] In one embodiment of the present invention, reference is made to Figure 13 and Figure 14 (The hollow arrow indicates the direction of gas flow).

[0189] In one embodiment of the present invention, the non-metallic rod may be made of nylon material.

[0190] In one embodiment of the present invention, 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 discharge unit 410, and the second metal mesh adsorption unit 430 is located on the other side of the metal mesh discharge unit 410. (Refer to...) Figure 5 (The hollow arrow indicates the direction of gas flow), in Figure 11 A 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 discharge unit 410. The first metal mesh adsorption unit 420 is located in front of the metal mesh discharge unit 410. The metal mesh discharge unit 410 is positioned between the two metal mesh adsorption units (the first metal adsorption unit 420 and the second metal adsorption unit 430) and is separated from the first metal adsorption unit 420 and the second metal adsorption unit 430 by a distance. The discharge beam 411 is directed toward the first multilayer metal mesh 421, and 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 discharge unit 410, removing most of the micron-sized particles, i.e., large particles, from the gas. After the gas has been purified by removing large particles through the electric field, it enters the second multilayer metal mesh 431 of the second metal adsorption unit 430. Through the physical adsorption of the multilayer metal mesh, the particles in the gas can be further adsorbed, improving the removal efficiency.

[0191] In one embodiment of the present invention, 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. Charged particles that have not been adsorbed after being purified by the electric field between the first metal adsorption unit 420 and the metal mesh discharge unit 410 are adsorbed by the positively charged second multilayer metal mesh 431, further improving the particle removal efficiency.

[0192] In one embodiment of the present invention, 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 discharge unit 410 is positioned between the two metal mesh adsorption units (the first metal adsorption unit 420 and the second metal adsorption unit 430) and is spaced apart from 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 the discharge beam 411 and the first multilayer metal mesh 421 form an electric field. The gas first enters the second metal adsorption unit 430, and through the physical adsorption of the second multilayer metal mesh 431, a portion of the 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 metal mesh discharge unit 410. 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.

[0194] In one embodiment of the present invention, 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 metal mesh discharge unit 410 and a second end face facing away from the metal mesh discharge unit 410. 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%.

[0195] It should be noted that, in this invention, the distance between the first metal mesh adsorption unit 420 and the metal mesh discharge unit 410 refers to the vertical distance from the free end of the discharge beam 411 on the metal mesh discharge unit 410 to the first multilayer metal mesh 421.
