[0040] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings so that the purpose, features and advantages of the present invention can be more clearly understood. It should be understood that the embodiments shown in the accompanying drawings are not intended to limit the scope of the present invention, but are only intended to illustrate the essential spirit of the technical solution of the present invention.

[0041] In the following description, certain specific details are set forth for the purpose of illustrating the various disclosed embodiments to provide a thorough understanding of the various disclosed embodiments. However, those skilled in the relevant art will recognize that the embodiments may be practiced without one or more of these specific details. In other cases, well-known devices, structures, and techniques associated with the present application may not be shown or described in detail to avoid unnecessarily obscuring the description of the embodiments.

[0042] References throughout the specification to "one embodiment" or "an embodiment" indicate that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, the appearances of "in one embodiment" or "in an embodiment" in various places throughout the specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any manner in one or more embodiments.

[0043] In the following description, in order to clearly show the structure and working mode of the present invention, many directional words will be used for description, but the words "front", "back", "left", "right", "outside", "inside", "outward", "inward", "up", "down", etc. should be understood as convenient terms and should not be understood as restrictive terms.

[0044] According to one aspect of the present invention, an electric field unit assembly is provided, which includes an electric field unit and an auxiliary adsorption mechanism, wherein the auxiliary adsorption mechanism is arranged on at least one side of the electric field unit and forms at least one chamber with the electric field unit, wherein the auxiliary adsorption mechanism has a porous structure to connect the outside of the chamber with the internal fluid of the chamber.

[0045] It should be noted that the above-mentioned electric field unit assembly can be used as an adsorption electrode of the electric field device. First, the auxiliary adsorption mechanism of the porous structure can filter out part of the particles in the gas at the air inlet and / or the air outlet by physical filtration. Secondly, the discharge electrode of the electric field device performs corona discharge and ionizes the gas in the chamber, so that the particulate matter in the gas acquires an electric charge, and the charged particulate matter moves toward the electric field unit and the auxiliary adsorption mechanism, and is deposited on the electric field unit and the auxiliary adsorption mechanism. When the gas enters in a direction that is not parallel to the electric field unit and / or the auxiliary adsorption mechanism, that is, the gas entry direction is not perpendicular to the ion flow direction in the electric field, compared with the electric field in which the gas entry direction is perpendicular to the ion flow direction, the present invention increases the residence time of the gas in the electric field, which can improve the charging efficiency of the particulate matter, and more particulate matter is deposited on the adsorption electrode, thereby improving the dust removal efficiency.

[0046] It should also be noted that when the auxiliary adsorption mechanism is made of a porous structural material with an electret property, the auxiliary adsorption mechanism is arranged in the active electric field formed by the discharge electrode and the electric field unit, that is, the auxiliary adsorption mechanism is arranged in the space charge generated by the corona discharge between the discharge electrode and the electric field unit. The space charge can enter the auxiliary adsorption mechanism with an electret property and then electret the auxiliary adsorption mechanism. The auxiliary adsorption mechanism after electret can form an electret electric field in the surrounding space, and the electrostatic adsorption effect of the electret electric field can enhance the purification of particulate matter. When the active electric field suddenly disappears, the electret electric field will not disappear, and the purification of particulate matter can continue. The present invention utilizes the dual electric field of the electret electric field and the active electric field to remove particulate matter, thereby improving the dust removal efficiency.

[0047] It is further noted that the centers of the vents on two adjacent adsorption plates in the same chamber are arranged on different planes perpendicular to the axis of the chamber, which can turbulent the gas flow in the chamber, further increasing the residence time of the gas in the electric field, increasing the frequency of close contact with the discharge electrode, and improving the charging efficiency and amount of particles; and when the gas forms a cyclonic flow, it is conducive to the separation of large particles. Combining the above two points, the dust removal efficiency is effectively improved. In addition, multiple adsorption plates are connected in sequence through connectors to form an electric field unit. The adsorption plates connected by connectors can not only achieve standardized and mass production, convenient processing, and high efficiency, but also the connector connection has the advantages of simple assembly and detachable packaging and transportation.

[0048] The particulate matter described in the present invention includes but is not limited to solid particles, liquid droplets, solid particles attached with liquid, aerosols, solid particles or liquid droplets in plasma state, etc., and may also be microorganisms such as bacteria and fungi.

The auxiliary adsorption mechanism 1200 with a porous structure can filter out part of the particles in the gas at the air inlet end and / or the air outlet end by physical filtration.

[0055] Figure 1B yes Figure 1AThe exploded schematic diagram of the electric field unit assembly is illustrated by taking the structures of the first chamber 1110 and the third chamber 1130 as examples, and the structures of other chambers are similar. The first adsorption plate 1101 and the second adsorption plate 1102 and the second auxiliary adsorption mechanism 1220 form a first chamber 1110, and the second adsorption plate 1102 and the fourth adsorption plate 1104 and the first auxiliary adsorption mechanism 1210 form a third chamber. The first adsorption plate 1101, the second adsorption plate 1102 and the fourth adsorption plate 1104 are provided with a plurality of ventilation holes 1500, and the centers of the ventilation holes 1500 on two adjacent adsorption plates are arranged on different planes perpendicular to the axial direction of the chamber, that is, the center of the first ventilation hole 1510 on the first adsorption plate 1101 and the center of the second ventilation hole 1520 on the second adsorption plate 1102 are arranged on different planes perpendicular to the axial direction of the first chamber 1110, and the center of the second ventilation hole 1520 on the second adsorption plate 1102 and the center of the third ventilation hole 1530 on the fourth adsorption plate 1104 are arranged on different planes perpendicular to the axial direction of the third chamber 1130. Preferably, each adsorption plate includes a plurality of vent holes, and the plurality of vent holes are arranged in at least one row along the axial direction, wherein the center of any vent hole on one of the two adjacent adsorption plates and the center of any vent hole on the other adsorption plate are arranged on different planes perpendicular to the axial direction. In the present embodiment, the center of the first vent hole 1510 on the first adsorption plate 1101 and the center of the third vent hole 1530 on the fourth adsorption plate 1104 are arranged on the same plane perpendicular to the axial direction of the chamber, however, in other embodiments, the center of the first vent hole 1510 on the first adsorption plate 1101 and the center of the third vent hole 1530 on the fourth adsorption plate 1104 may also be arranged on different planes perpendicular to the axial direction of the chamber. In the present embodiment, the first air holes 1510 on the first adsorption plate 1101 are evenly distributed in two rows along the axial direction and are arranged from one end of the first adsorption plate 1101 to the other end of the first adsorption plate 1101, the second air holes 1520 on the second adsorption plate 1102 are evenly distributed in two rows along the axial direction and are arranged from one end of the second adsorption plate 1102 to the other end of the second adsorption plate 1102, and the third air holes 1530 on the fourth adsorption plate 1104 are evenly distributed in two rows along the axial direction and are arranged from one end of the fourth adsorption plate 1104 to the other end of the fourth adsorption plate 1104. In other embodiments, the air holes can also be axially distributed in a part of the adsorption plate according to the actual needs of air intake or exhaust.In the present embodiment, the first air hole 1510, the second air hole 1520 and the third air hole 1530 are circular holes with the same diameter. In other embodiments, the air holes may be elliptical holes, triangular holes, quadrilateral holes or pentagonal holes. The diameters of the air holes on different adsorption plates may also be different, but it is necessary to ensure that the gas cannot be discharged directly from the chamber through the air holes without obstruction, that is, if two adsorption plates in the same chamber are overlapped together, the air holes on different adsorption plates will not completely overlap or the air holes on one adsorption plate will completely include the air holes on the adjacent adsorption plate, thereby ensuring that the gas will encounter obstructions when flowing, so that when the airflow flows into one adsorption plate and flows out from the air holes on other adsorption plates in the same chamber, the airflow changes direction and even forms a cyclone path in the chamber before being discharged from the chamber through the air outlet.

[0056] Reference Figure 1B , taking the gas direction of the first chamber 1110 and the third chamber 1130 as an example, the gas direction of other electric field units is analogous. The gas enters the first chamber 1110 through the porous structure of the second auxiliary mechanism 1220, then enters the third chamber through the second vent 1520, and finally enters the fourth chamber 1140 through the third vent 1530 or is discharged through the first auxiliary adsorption mechanism 1210. Since the hole center of the second vent 1520 and the hole center of the third vent 1530 are arranged on different planes perpendicular to the axial direction of the third chamber 1130, the gas flow direction of the gas passing through the third chamber 1130 is turbulent, which further increases the residence time of the gas in the two chambers, which is conducive to increasing the frequency of close contact with the discharge electrode. The closer to the discharge electrode, the higher the gas ionization efficiency, which improves the particle charging efficiency and charge; and when the gas forms a cyclonic flow, it is conducive to the separation of large particles. Combining the above two points, the dust removal efficiency is effectively improved. In this embodiment, since ventilation holes can be opened on the adsorption plate of each chamber, the ventilation holes on different adsorption plates in the same chamber are arranged on different planes perpendicular to the axis of the chamber. As a result, the gas in each chamber can come from multiple adjacent chambers or flow to multiple adjacent chambers. The gas flow is highly turbulent, and the air flow passing through the discharge electrode becomes more, which increases the charging efficiency and charge amount of particles in the gas and improves the dust removal efficiency.

[0057] Reference Figure 1BThe auxiliary adsorption mechanism 1200 is composed of a 60-mesh polytetrafluoroethylene film. Since polytetrafluoroethylene is an electret material, the auxiliary adsorption mechanism 1200 is arranged in the active electric field formed by the discharge electrode and the electric field unit, that is, the auxiliary adsorption mechanism 1200 is arranged in the space charge generated by corona discharge between the discharge electrode and the electric field unit. The space charge can enter the auxiliary adsorption mechanism 1200 with electret performance and then electret the auxiliary adsorption mechanism 1200. After electret, the auxiliary adsorption mechanism 1200 can form an electret electric field in the surrounding space, and the electrostatic adsorption effect of the electret electric field can enhance the purification of particulate matter. When the active electric field suddenly disappears, the electret electric field will not disappear, and the purification of particulate matter can continue. The present invention uses the dual electric field of the electret electric field and the active electric field to remove particulate matter, thereby improving the dust removal efficiency. In other embodiments, the aperture of the auxiliary adsorption mechanism can also be selected from one or more of 40 meshes to 100 meshes. The finer the aperture, the greater the wind resistance of the gas and the greater the energy consumption. Preferably, the aperture of the auxiliary adsorption mechanism can also be selected from one or more of 40 meshes to 80 meshes; it can also be composed of a multilayer film, and the porous structure overlaps and penetrates each other. In other embodiments, the material of the auxiliary adsorption mechanism can be selected from one or more of a conductive material or an electret material, wherein the conductive material can be selected from one or more of a metal or an alloy, and the electret material can be selected from an inorganic compound with an electret property and / or an organic compound with an electret property, wherein the inorganic compound is selected from one or more combinations of silicon dioxide, barium titanate, lead zirconate titanate, zinc oxide, tantalum oxide, aluminum oxide, titanium oxide, and silicon nitride, wherein the organic compound is selected from one or more combinations of fluorocarbon polymers, polycarbonate, polypropylene, polyethylene, polyvinyl chloride, natural wax, resin, and rosin, wherein the fluorocarbon polymer is selected from one or more combinations of polytetrafluoroethylene, polyvinylidene fluoride, polyperfluoroethylene propylene, soluble polyperfluoroethylene propylene, and soluble polytetrafluoroethylene.

[0058] Reference Figure 1B The electric field unit assembly 1000 further includes a top plate and a bottom plate (not shown in the figure), which are respectively connected to the top and bottom ends of the electric field unit and seal the top and bottom of the chamber. Preferably, the electric field unit assembly 1000 further includes an end plate 1600 and a reinforcement member 1700, which is arranged on the outer surface of the auxiliary adsorption mechanism 1200 and fixedly connected to the end plate 1600.

The auxiliary adsorption mechanism 3200 is arranged on at least one side of the electric field unit 3100 and encloses at least one chamber with the electric field unit 3100, wherein the auxiliary adsorption mechanism 3200 has a porous structure to connect the outside of the chamber with the internal fluid of the chamber.

The similarities between the electric field unit assembly and the above are not repeated, and this embodiment only describes the differences.

[0060] Reference Figure 2The electric field unit 3100 is composed of a plurality of adsorption plates and forms an undulating structure. The process of the electric field unit with an undulating structure formed by splicing a plurality of adsorption plates is not only convenient to process and efficient, but also can be standardized and mass-produced. The first adsorption plate 3101, the second adsorption plate 1102 and the third adsorption plate 3103 and the second auxiliary adsorption mechanism 3220 enclose the first chamber 3110, the first adsorption plate 1101, the fourth adsorption plate 3103 and the fifth adsorption plate 3105 and the first auxiliary adsorption mechanism 3210 enclose the second chamber 3120, and the third adsorption plate 3103, the sixth adsorption plate 3106 and the seventh adsorption plate 3107 and the first auxiliary adsorption mechanism 3210 enclose the third chamber 3130. Two adjacent adsorption plates are connected to each other and form a certain angle, the range of the angle is between 90°-179°, preferably, the angle is 120°, and the angle is the angle between the adsorption plates, not the angle formed by the adsorption plate and the straight line where the adsorption plate is located. The first adsorption plate 3101 and the second adsorption plate 3102 are connected to each other and form a certain angle, the second adsorption plate 3102 and the third adsorption plate 3103 are connected to each other and form a certain angle, and the third adsorption plate 3103 and the sixth adsorption plate 3106 are connected to each other and form a certain angle, and the range of the angle is between 90°-179°. Preferably, the angle is 120°. In addition, the first adsorption plate 3101, the second adsorption plate 1102 and the third adsorption plate 3103 form a first peak 3301, the first adsorption plate 1101, the fourth adsorption plate 3103 and the fifth adsorption plate 3105 form a first valley 3302, and the third adsorption plate 3103, the sixth adsorption plate 3106 and the seventh adsorption plate 3107 form a second valley 3303. In other words, a first chamber 3110 is formed between the first valley 3302, the second valley 3303 and the first peak 3301. Similarly, the seventh adsorption plate 3107, the eighth adsorption plate 3108 and the ninth adsorption plate 3109 form a second peak 3304, that is, a third chamber 3130 is formed between the first peak 3301 and the second peak 3304 and the second valley 3303. It will be understood by those skilled in the art that, in other embodiments, the electric field unit may be composed of an adsorption plate, which may be bent by 3D printing or casting and other processes according to the shape and structure of the actual chamber. In other embodiments, the number of chambers in the electric field unit assembly is not limited thereto, and the number of chambers may be adjusted according to the actual amount of gas to be purified, and the arrangement of the multiple chambers may be adjacent and / or non-adjacent in any direction of up, down, left, right, front, or back. In this embodiment, in order to facilitate production and processing, the structures and shapes of the four chambers are the same, however, in other embodiments, the structures and sizes of the multiple chambers may be different or partially the same depending on the storage conditions of the device space or other factors. Reference Figure 2, the first adsorption plate 3101, the third adsorption plate 3103, the fifth adsorption plate 3105, the seventh adsorption plate 3107 and the ninth adsorption plate 3109 are evenly provided with two rows of vents, and the second adsorption plate 3102, the fourth adsorption plate 3104, the sixth adsorption plate 3106 and the eighth adsorption plate 3108 are not provided with vents. This design allows the gas to pass through at least two chambers before being discharged. For example, the gas enters the first chamber 3110 from the second auxiliary mechanism 3220, and enters the second chamber 3120 or the third chamber 3130 through the first adsorption plate 3101 or the third adsorption plate 3103, respectively, and then part of the gas is directly discharged from the first auxiliary adsorption mechanism 3210, and part of the gas enters other chambers and then is discharged from the first auxiliary adsorption mechanism 3210. This design can make the gas in the electric field unit assembly highly turbulent, further increase the residence time of the gas in the chamber, and improve the dust removal efficiency.

[0061] Figure 3 It is a three-dimensional exploded schematic diagram of an electric field device according to an embodiment of the present invention, wherein the electric field device 2000 comprises an adsorption electrode 2100 and a discharge electrode 2200, wherein the adsorption electrode 2100 is composed of an electric field unit assembly, so the adsorption electrode 2100 can also be referred to as an electric field unit assembly 2100, the electric field unit assembly 2100 comprises an electric field unit 2110 and an auxiliary adsorption mechanism 2120, the auxiliary adsorption mechanism comprises a first auxiliary adsorption mechanism 2121 and a second auxiliary adsorption mechanism 2122, the first auxiliary adsorption mechanism 2121 and the second auxiliary adsorption mechanism 2122 are arranged relative to each other and form an interlayer space 2123, the electric field unit 2110 is arranged in the interlayer space 2123, the auxiliary adsorption mechanism 2120 and the electric field unit 2110 enclose at least one chamber, wherein the auxiliary adsorption mechanism 2120 has a porous structure to connect the outside of the chamber with the internal fluid of the chamber, wherein the auxiliary adsorption mechanism 2120 is composed of a 60-mesh polytetrafluoroethylene film. The similarities between the electric field unit assembly and the above are not described in detail, and only the differences are described in this embodiment.

[0062] Reference Figure 3, the electric field unit 2110 is composed of a plurality of adsorption plates. The electric field unit 2110 and the first auxiliary adsorption mechanism 2121 and the second auxiliary adsorption mechanism 2122 enclose 8 chambers. The structure of the first chamber 2310 is used as an example for explanation, and the structures of other chambers are analogous. Two adjacent adsorption plates are arranged in parallel, that is, the first adsorption plate 2111 and the second adsorption plate 2112 are arranged in parallel, and enclose the first chamber 2310 with the first auxiliary adsorption mechanism 2121 and the second auxiliary adsorption mechanism 2122. The first chamber 2310 has a quadrilateral cross-section, and the cross-sectional direction is perpendicular to the axial direction of the first chamber 2310. In other embodiments, the adsorption plates of the electric field unit are not placed in parallel, and the electric field unit can also enclose a chamber with a polygonal cross-section with the auxiliary adsorption mechanism, and the cross-sectional direction is perpendicular to the axial direction of the chamber. The polygon can be a pentagon, a hexagon, etc. Preferably, the cross-section of the chamber is a regular polygon. In other embodiments, the number of chambers in the electric field unit assembly is not limited thereto, and the number of chambers can be adjusted according to the actual amount of gas to be purified, and the arrangement of the multiple chambers can be adjacent and / or non-adjacent in any direction of top, bottom, left, right, front, and back. In this embodiment, in order to facilitate production and processing, the structures and shapes of the eight chambers are the same, however, in other embodiments, according to the storage conditions of the device space or other factors, the structures and sizes of the multiple chambers may be different or partially the same.

[0063] Reference Figure 3 In this embodiment, no vent is provided on the adsorption plate of the electric field unit 2110, that is, the gases in different chambers cannot circulate with each other. The gas in each chamber enters the chamber through the auxiliary adsorption mechanism and is then discharged from the chamber through the auxiliary adsorption mechanism. The resistance to air flow is reduced, which can reduce energy consumption and increase ventilation volume.

[0064] Reference Figure 3, the discharge electrode 2200 is arranged in each chamber and is composed of a conductor extending along the axial direction of the chamber. In other embodiments, the discharge electrode can be arranged in part of the chamber. In this embodiment, the chamber has a quadrilateral cross-section, and the discharge electrode passes through the longitudinal center line of the chamber. The longitudinal center line is a line extending along the axial direction of the chamber and passing through the intersection of the long side symmetry axis and the short side symmetry axis of the rectangular cross-section. However, in other embodiments, the cross-section of the chamber can be other polygons, and the discharge electrode passes through the longitudinal center line of the chamber. The longitudinal center line is a line extending along the axial direction of the chamber and passing through the midpoint of the polygonal cross-section. For example, when the cross-section of the chamber is a triangle, the longitudinal center line is a line extending along the axial direction of the chamber and passing through the intersection of the angle bisector of the triangular cross-section. Preferably, when the cross-section of the chamber is a regular polygon, the discharge electrode passes through the center of the inscribed circle of the cross-section. For example, when the cross-section of the chamber is a regular triangle, the discharge electrode preferably passes through the center of the inscribed circle of the cross-section, where the discharge efficiency is the highest. Those skilled in the art will appreciate that, due to actual processing conditions, the discharge electrode may be arranged slightly away from the longitudinal center line of the chamber or the center of the inscribed circle of the cross section. The above cross-sectional directions are perpendicular to the axial direction of the chamber.

[0065] In this embodiment, the discharge electrode 2200 is a slender needle-shaped conductor. In other embodiments, the discharge electrode may also be a polygonal, burr-shaped, threaded rod-shaped or columnar conductor. In this embodiment, the diameter of the discharge electrode 2200 is 0.1-10 mm. Preferably, the diameter of the discharge electrode 2200 is 0.2-5 mm. In one embodiment, the discharge electrode 2200 is in the shape of a slender strip and is made of any one of 304 stainless steel, titanium, tungsten, and iridium gold. Preferably, the discharge electrode is made of iridium gold.

[0066] Reference Figure 3, the electric field unit 2110 is electrically connected to one electrode of the power source, the discharge electrode 2200 is electrically connected to the other electrode of the power source, and the electric field unit 2110 and the discharge electrode 2200 form an active electric field. Preferably, the electric field unit 2110 is electrically connected to the anode of the power source, and the discharge electrode 2200 is electrically connected to the cathode of the power source, that is, the electric field unit 2110 is the anode, and the discharge electrode 2200 is the cathode. However, in other embodiments, the electric field unit 2110 may also be electrically connected to the cathode of the power source, and the discharge electrode 2200 may be electrically connected to the anode of the power source, that is, the electric field unit 2110 is the cathode, and the discharge electrode 2200 is the anode. When the electric field unit 2110 is electrically connected to the anode of the power supply and the discharge electrode 2200 is electrically connected to the cathode of the power supply, the auxiliary adsorption mechanism 2120 with the electret property is arranged in the active electric field formed by the discharge electrode and the electric field unit, that is, the auxiliary adsorption mechanism 2120 is arranged in the space charge generated by the corona discharge between the discharge electrode and the electric field unit. The space charge can enter the auxiliary adsorption mechanism 2120 with the electret property and then electret the auxiliary adsorption mechanism 2120. After electret, the auxiliary adsorption mechanism 2120 can form an electret electric field in the surrounding space. When the gas enters or is discharged from the chamber through the auxiliary adsorption mechanism 2120, the auxiliary adsorption mechanism 2120 can not only filter out part of the particles in the gas at the air inlet and / or the air outlet by physical filtration, but also can use the electrostatic adsorption effect of the electret electric field to enhance the purification of particulate matter in the gas. Moreover, since the discharge electrode 2200 discharges and ionizes, the particulate matter in the gas acquires a negative charge, and the negatively charged particulate matter moves toward the electric field unit 2110 and / or the auxiliary adsorption mechanism 2120 and is deposited on the electric field unit 2110 and / or the auxiliary adsorption mechanism 2120. When the active electric field suddenly disappears, the electret electric field will not disappear, and the auxiliary adsorption mechanism 2120 can continue to purify the particulate matter. The present invention uses the dual electric field of the electret electric field and the active electric field to remove particulate matter, thereby improving the dust removal efficiency.

[0067] Figure 4It is a top view and cross-sectional schematic diagram of the electric field device of the present invention, the electric field device 4000 includes an adsorption electrode 4100 and a discharge electrode 4200, wherein the adsorption electrode 4100 is composed of an electric field unit assembly, so the adsorption electrode 4100 can also be called an electric field unit assembly 4100, the electric field unit assembly 4100 includes an electric field unit 4110 and an auxiliary adsorption mechanism 4120, the auxiliary adsorption mechanism includes a first auxiliary adsorption mechanism 4121 and a second auxiliary adsorption mechanism 4122, the first auxiliary adsorption mechanism 4121 and the second auxiliary adsorption mechanism 4122 are arranged relative to each other and form an interlayer space, the electric field unit 4110 is arranged in the interlayer space, the auxiliary adsorption mechanism 4120 and the electric field unit 4110 enclose at least one chamber, wherein the auxiliary adsorption mechanism 4120 has a porous structure to connect the outside of the chamber with the internal fluid of the chamber, wherein the auxiliary adsorption mechanism 4120 is composed of a 60-mesh polytetrafluoroethylene film. The similarities between the electric field unit assembly, discharge electrode or electric field device and the above are not described in detail, and only the differences are described in this embodiment.

[0068] Reference Figure 4 , the electric field unit 4110 is composed of two adsorption plates, the first adsorption plate 4111 and the second adsorption plate 4112 are arranged in parallel, and together with the first auxiliary adsorption mechanism 4121 and the second auxiliary adsorption mechanism 4122, form a chamber 4310, and the chamber 4310 has a quadrilateral cross-section, and the cross-section direction is perpendicular to the axial direction of the chamber 4310. In this embodiment, the first auxiliary mechanism 4121 and the second auxiliary adsorption mechanism 4122 are arranged in parallel, and the first adsorption plate 4111 and the second adsorption plate 4112 form a certain angle β with the first auxiliary adsorption mechanism 4121 and the second auxiliary adsorption mechanism 4122, wherein 0°<β≤90°, that is, the chamber 4310 has a parallelogram or rectangular cross-section.

[0069] Reference Figure 4, the first adsorption plate 4111 is provided with a first vent hole 4131 and a second vent hole 4132, the second adsorption plate 4112 is provided with a third vent hole 4133 and a fourth vent hole 4134, and the centers of the vent holes on the two adjacent parallel adsorption plates 4110 are arranged on different planes that are perpendicular to the adsorption plate 4110 and parallel to the axial direction of the chamber 4310. In this embodiment, the above-mentioned plane is a plane along the direction of arrow M. For example, the third vent hole 4133 and the first vent hole 4131 are arranged on different planes that are perpendicular to the adsorption plate 4110 and parallel to the axial direction of the chamber 4310, and the third vent hole 4133 and the second vent hole 4132 are arranged on different planes that are perpendicular to the adsorption plate 4110 and parallel to the axial direction of the chamber 4310. In other embodiments, each of the adsorption plates includes a plurality of vent holes, and the plurality of vent holes are arranged in at least one row along the axial direction, wherein the center of any vent hole on one of the two adjacent parallel adsorption plates and the center of any vent hole on the other adsorption plate are arranged on different planes perpendicular to the adsorption plate and parallel to the axial direction of the chamber.

[0070] Reference Figure 4 , the dotted arrow is a schematic path of the direction of part of the gas. Since the third air hole 4133 and the second air hole 4132 are arranged on different planes that are perpendicular to the adsorption plate 4110 and parallel to the axial direction of the chamber 4310, part of the gas enters the chamber 4310 from the third air hole 4133, passes through at least two obstructions and turbulences of the first adsorption plate 4111 and the second adsorption plate 4112, and is finally discharged from the second air hole 4132. The gas flow direction is more chaotic, which further increases the residence time of the gas in the chamber, and is conducive to increasing the frequency of close contact with the discharge electrode. The closer to the discharge electrode, the higher the gas ionization efficiency, which improves the charging efficiency and charge of the particles, and effectively improves the dust removal efficiency.

[0071] Reference Figure 4 In this embodiment, the discharge electrode 4200 passes through the longitudinal center line of the chamber. The longitudinal center line is a line extending along the axial direction of the chamber 4310 and passing through the intersection of the long side symmetry axis and the short side symmetry axis of the parallelogram or rectangular cross-section. The discharge efficiency is highest here. However, in other embodiments, at least two discharge electrodes are arranged in at least one chamber; preferably, the electric field unit is composed of a plurality of adsorption plates, and a chamber is formed between at least two adsorption plates. The distance between at least two discharge electrodes and each adsorption electrode constituting the chamber is equal. This design is conducive to further increasing the discharge efficiency; more preferably, at least two discharge electrodes are evenly distributed in the chamber along the transverse center line of the chamber. Refer to Figure 4Since the chamber 4310 has a parallelogram or rectangular cross-section, the intersection points of the first adsorption plate 4111 and the second adsorption plate 4112 with the first auxiliary adsorption mechanism 4121 and the second auxiliary adsorption mechanism 4122 are a, b, c and d respectively, and the transverse center line is the line connecting the midpoint of the line segment ab and the midpoint of the line segment cd, or the line connecting the midpoint of the line segment ac and the midpoint of the line segment bd; wherein the short transverse center line is the line connecting the midpoint of the line segment ab and the midpoint of the line segment cd, and at least two discharge electrodes are evenly arranged on the short transverse center line.
