Description

Technical Field

[0001] This invention relates to the field of electric fields, and more specifically to an electric field unit component, an electric field adsorption device, and an electric field device. Background Technology

[0002] Currently, electrostatic technology is widely used in the field of gas purification. When gas passes through an electrostatic field, it is ionized. After particulate matter in the gas combines with charged ions, it tends to move towards the electrode with the opposite polarity of the charged ions and is deposited. It can be seen that the particulate matter removal rate is related to the charging efficiency of the particulate matter. In current electrostatic gas purification devices, the direction of gas entering the electric field is perpendicular to the direction of ion flow in the electric field, which has drawbacks such as short residence time of gas in the electric field and low charging efficiency.

[0137] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so as to better understand the purpose, features and advantages of the present invention. It should be understood that the embodiments shown in the drawings are not intended to limit the scope of the present invention, but are only for illustrating the essential spirit of the technical solution of the present invention.

[0138] In the following description, certain specific details are set forth for the purpose of illustrating various disclosed embodiments in order to provide a thorough understanding of the various disclosed embodiments. However, those skilled in the art will recognize that embodiments may be practiced without one or more of these specific details. In other instances, well-known apparatuses, structures, and techniques associated with this application may not have been shown or described in detail to avoid unnecessarily obscuring the description of the embodiments.

[0139] Throughout this specification, references to "an 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. Therefore, the appearance of "in an embodiment" or "an embodiment" in various places throughout the specification does not necessarily refer to the same embodiment. Furthermore, a particular feature, structure, or characteristic may be combined in any manner in one or more embodiments.

[0140] In the following description, in order to clearly demonstrate the structure and working method of the present invention, a number of directional terms will be used. However, terms such as "front", "back", "left", "right", "outside", "inside", "outward", "inward", "up", and "down" should be understood as convenient terms and not as limiting terms.

[0141] According to one aspect of the present invention, an electric field unit is provided having an axially extending channel, a sidewall formed around the channel, and an inlet for gas to enter the channel and an outlet for gas to exit the channel.

[0142] It should be noted that the gas does not flow along the axial direction of the channel, which can be understood as the gas not flowing from one end of the channel to the other along the axial direction of the channel; the gas enters the channel through the inlet and exits the channel through the outlet.

[0143] It should be noted that the aforementioned electric field unit can serve as the adsorption electrode of the electric field device. The discharge electrode of the electric field device discharges and ionizes. After the particulate matter in the gas combines with the charged ions, the particulate matter in the gas gains a charge. The charged particulate matter moves towards the adsorption electrode and is deposited there. When the gas enters in a direction that is not parallel to the sidewall of the electric field unit, that is, the gas entry direction is not perpendicular to the ion flow direction in the electric field, compared with an electric field where the gas entry direction is perpendicular to the ion flow direction, this invention increases the residence time of the gas in the electric field, which can improve the charging efficiency of the particulate matter and allow more particulate matter to be deposited on the adsorption electrode, thereby improving the dust removal efficiency.

[0144] It is also important to note that when the centers of the inlet and outlet are arranged on different planes perpendicular to the axial direction, the gas flow in the channel can be disrupted, 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 charge of the particles. Moreover, when the gas forms a cyclone flow, it is beneficial for the separation of large particles. Combining these two points, the dust removal efficiency can be effectively improved. Additionally, it is important to note that if at least one of the sidewalls does not have an inlet or outlet along the centerline extending along the channel direction, the area at the centerline position is not damaged. After the particles are charged, they are directly adsorbed near the centerline of the adsorption electrode, increasing the amount of particles adsorbed on the adsorption electrode, thereby improving the dust removal efficiency. The particles include, but are not limited to, solid particles, droplets, solid particles with attached liquid, aerosols, plasma-state solid particles or droplets, and can also be microorganisms such as bacteria and fungi.

[0145] Figure 1 This is a three-dimensional schematic diagram of an electric field device according to an embodiment of the present invention. The electric field device 20 includes a discharge electrode 209 and an adsorption electrode 200. The adsorption electrode 200 is composed of an electric field adsorption device.

The channel of each electric field unit 2000 is surrounded by the sidewall, and the cross section perpendicular to the axial direction is an equilateral triangle. In other embodiments, the number of electric field units in the electric field adsorption device is not limited to this. The number of electric field units can be adjusted according to the actual gas flow rate to be purified. Moreover, the arrangement of multiple electric field units can be adjacent and / or non-adjacent in any direction, such as up, down, left, right, front, or back. In this embodiment, the twelve electric field units have the same structure and shape for ease of production and processing. However, in other embodiments, depending on the storage conditions of the device space or other factors, the structure and size of multiple electric field units may be different or partially the same.

[0146] Reference Figure 1The structure of the first electric field unit 2100 and the second electric field unit 2200 will be used as an example for explanation, and the structure of other electric field units can be deduced by analogy. The first electric field unit 2100 has a first channel 2110 extending along the axial direction, the axial direction being the same as the direction of the central axis of the electric field unit 2100 extending along the first channel 2110. A sidewall 2120 is formed around the first channel 2110. The sidewall 2120 is provided with a first air inlet 213 for gas to enter the channel 2110 and a first air outlet 214 for gas to exit the channel. There are multiple first air inlets 213 and first air outlets 214. Preferably, the multiple first air inlets 213 and multiple first air outlets 214 have the same diameter. The multiple first air inlets 213 are evenly arranged in a row along the axial direction on the first sidewall 2121. The multiple first air outlets 214 are evenly arranged in a row along the axial direction on the second sidewall 2122. No air inlets or air outlets are provided on the third sidewall 2123. The center of the first air inlet 213 and the center of the first air outlet 214 are arranged on different planes perpendicular to the axial direction. The first electric field unit 2100 and the second adsorption unit 2200 share a second sidewall 2122. The two surfaces of the second sidewall 2122 face the first channel 2110 of the first electric field unit 2100 and the second channel 2210 of the second electric field unit 2200, respectively. That is, the first air outlet 214 on the second sidewall 2122 of the first adsorption unit 2100 is used as the second air inlet of the second sidewall 2122 of the second adsorption unit 2200 to ensure that the gas can directly enter the second electric field unit 2200 from the first electric field unit 2100. Multiple second air outlets 224 are opened on the fourth sidewall 2222 of the second adsorption unit 2200 and are evenly arranged in a row along the axial direction. No air inlet and / or air outlet are opened on the fifth sidewall 2223 of the second adsorption unit 2200.

[0147] Reference Figure 1 Each discharge electrode 209 is disposed within the channel of its corresponding electric field unit 2000. Since the cross-section of each channel of the electric field unit 2000, formed by the sidewalls surrounding it and perpendicular to the axial direction, is an equilateral triangle, the discharge electrode 209 is preferably disposed parallel to the sidewall of the channel and passes through the center of the inscribed circle of the corresponding electric field unit 2000's cross-section, where the discharge efficiency is highest. It should be noted that the cross-section here refers to the cross-section of the electric field unit 2000 perpendicular to the axial direction of the channel. For example, the first discharge electrode 219 is disposed within the channel of the first electric field unit 2100, and is preferably disposed parallel to the sidewall of the channel and passes through the center of the inscribed circle of the first electric field unit 2100's cross-section. The relationship between other discharge electrodes and electric field units is similar and will not be detailed here.

[0148] Continue to refer to Figure 1All electric field units 2000 are electrically connected to the same pole of the power supply, and all discharge electrodes 209 are electrically connected to the other pole of the power supply. For example, taking the first electric field unit 2100 and the second electric field unit 2200 as examples, the first electric field unit 2100 is electrically connected to the anode of the power supply, while the first discharge electrode 219 is electrically connected to the cathode of the power supply; and the second electric field unit 2200 is electrically connected to the anode of the power supply, while the second discharge electrode 229 is electrically connected to the cathode of the power supply. The first electric field unit 2100 and the first discharge electrode 219 form a first electric field, and the second electric field unit 2200 and the second discharge electrode 229 form a second electric field.

[0149] However, in other embodiments, the multiple electric field units can be divided into two groups, arranged in two or more rows. Each row of electric field units is in the same group. The first group of electric field units is electrically connected to the anode of the power supply, and the corresponding first group of discharge electrodes is electrically connected to the cathode of the power supply. The second group of electric field units is electrically connected to the cathode of the power supply, and the corresponding second group of discharge electrodes is electrically connected to the anode of the power supply. When the airflow passes successively through the electric fields formed by the first group of electric field units and the first group of discharge electrodes, and the second group of electric field units and the second group of discharge electrodes, the particulate matter in the gas acquires negative and positive charges, respectively. Negatively charged particulate matter is deposited on the first group of electric field units, and positively charged particulate matter is deposited on the second group of electric field units, thus improving dust removal efficiency.

[0150] Reference Figure 1 Taking the gas flow direction of the first electric field unit 2100 and the second electric field unit 2200 as an example, the gas flow direction of other electric field units is similar and will not be described in detail. Since the centers of the first inlet 213 and the first outlet 214 in the first electric field are arranged on different planes perpendicular to the axial direction, and the centers of the second inlet 224 and the second outlet 224 in the second electric field are arranged on different planes perpendicular to the axial direction, the gas flow direction is disordered as the gas passes through the first and second electric fields, which further increases the residence time of the gas in the two electric fields and increases the frequency of close contact with the first discharge electrode 219 and the second discharge electrode 229. The closer to the discharge electrode 209, the higher the gas ionization efficiency, which improves the charging efficiency and charge of the particulate matter. Moreover, when the gas forms a cyclone flow direction, it is conducive to the separation of large particles. Combining the above two points, the dust removal efficiency is effectively improved.

[0151] In other embodiments, an air inlet can be formed on the fifth sidewall 2223 of the second electric field unit 2200, allowing airflow between the second and third electric field units 2200, enabling gas to flow from the third electric field unit 2300 to the second electric field unit 2200. However, in other embodiments, an air inlet or outlet can be formed on the sidewall of each electric field unit, resulting in gas originating from or flowing to multiple adjacent electric field units. This highly turbulent gas flow increases the amount of airflow near the discharge electrode, increasing the charge efficiency and charge of particles in the gas, thus improving dust removal efficiency.

[0152] Figure 2A This is a three-dimensional schematic diagram of an electric field unit according to an embodiment of the present invention. The electric field unit 710 has a channel 711 extending along the axial direction, and a side wall 712 is formed around the channel 711. The side wall 712 is provided with an air inlet 713 for gas to enter the channel 711 and an air outlet 714 for gas to exit the channel 711. The center of the air inlet 713 and the center of the air outlet 714 are arranged on different planes perpendicular to the axial direction.

[0153] Reference Figure 2A The electric field unit 710 has an axially extending channel 711, the axial direction being the same as the direction of the central axis of the electric field unit 710 extending along the channel. Three sidewalls 712 are formed around the channel 711, including a first sidewall 7121, a second sidewall 7122, and a third sidewall 7123. The first sidewall 7121, the second sidewall 7122, and the third sidewall 7123 have equal lengths along the axial direction of the electric field unit 710. The cross-section of the channel 711 surrounded by the first sidewall 7121, the second sidewall 7122, and the third sidewall 7123 is preferably an equilateral triangle, meaning a cross-section perpendicular to the axial direction. However, in other embodiments, the electric field unit may also include more than three sidewalls; for example, the electric field unit may include three, four, five, six, or even more sidewalls. The cross-section of the channel surrounded by the sidewalls may be triangular, quadrilateral, pentagonal, hexagonal, or other polygonal shapes. Preferably, the cross-section of the channel surrounded by the sidewalls is a regular polygon; the electric field unit may also include only one sidewall, that is, the cross-section of the channel surrounded by the sidewalls is circular or elliptical; preferably, the interior angle of the cross-section of the regular polygon formed by the channel surrounded by the sidewalls is a divisor of 360, which is beneficial for seamless splicing of multiple electric field units in one plane at 360 degrees, simplifying the manufacturing process; more preferably, the cross-section of the channel surrounded by the sidewalls is an equilateral triangle or a regular hexagon.

[0154] In one embodiment, the first sidewall 7121, the second sidewall 7122, and the third sidewall 7123 each have a sidewall body and folded edges formed by bending from the sidewall body along both ends perpendicular to the channel. The connector is disposed on the folded edges of two adjacent sidewalls to fix the two adjacent sidewalls together. Because sidewalls connected using connectors can be standardized and mass-produced, are easy to process, and highly efficient, the connector connection also has the advantages of simple assembly, detachability, and ease of packaging and transportation.

[0155] Reference Figure 2A The first sidewall 7121 has a first sidewall main body 71211 and a first sidewall left folded edge 71212 and a first sidewall right folded edge 71213 formed by bending from both ends of the first sidewall main body 71211, the second sidewall 7122 has a second sidewall main body 71221 and a second sidewall left folded edge 71222 and a second sidewall right folded edge 71223 formed by bending from both ends of the second sidewall main body 71221, and the third sidewall 7123 has a third sidewall main body 71231 and a third sidewall left folded edge 71232 and a third sidewall right folded edge 71233 formed by bending from both ends of the third sidewall main body 71231. Specifically, the left folded edge 71212 and the right folded edge 71213 of the first sidewall are parallel to each other; the left folded edge 71222 and the right folded edge 71223 of the second sidewall are parallel to each other; and the left folded edge 71232 and the right folded edge 71233 of the third sidewall are parallel to each other and perpendicular to the main body 71231 of the third sidewall. It should be noted that the terms "left" and "right" here are merely to distinguish the two folded edges and do not constitute a limitation on their orientation.

[0156] Continue to refer to Figure 2A Each sidewall's folded edge extends along the extension direction of the channel 711, and the folded edges of adjacent sidewalls are aligned and connected by connectors, thereby fixing the adjacent sidewalls together. For example, each folded edge has multiple through holes 718 arranged along the extension direction of the channel, and the connectors pass through and are fixed within the through holes 718, thereby fixing the adjacent sidewalls together. Preferably, each folded edge has through holes 718 at both ends of the channel. Preferably, each folded edge has through holes at its ends, and the connectors can be rivets, screws, etc., and adjacent sidewalls are connected by rivet connections, bolt connections, screw connections, etc. In this embodiment, adjacent sidewalls are riveted together sequentially by rivets.

[0157] Reference Figure 2A , Figure 3In this embodiment, the right folded edge 71213 of the first sidewall 7121 and the right folded edge 71223 of the second sidewall 7122 are riveted together by rivets 99 to form a connecting top. The left folded edge 71222 of the second sidewall 7122 and the left folded edge 71232 of the third sidewall 7123 are riveted together by rivets 99 to form a first connecting bottom. The left folded edge 71212 of the first sidewall 7121 and the right folded edge 71233 of the third sidewall 7123 are riveted together by rivets 99 to form a second connecting bottom.

[0158] In one embodiment, refer to Figure 2A The side wall 712 is provided with an air inlet 713 for gas to enter the channel 711 and an air outlet 714 for gas to exit the channel 711. The air inlet 713 and the air outlet 714 are preferably arranged on different side walls. For example, the air inlet 713 is arranged on the third side wall 7123, and the air outlet 714 includes a first air outlet 7141 and a second air outlet 7142. The first air outlet 7141 is arranged on the first side wall 7121, and the second air outlet 7142 is arranged on the second side wall 7122. In this embodiment, air inlets 713 or air outlets 714 are arranged on all three sidewalls of the electric field unit 710. However, it should be understood that in other embodiments, the air inlets and / or air outlets may be arranged on part of the sidewalls of the electric field unit. For example, the air inlet 713 may be arranged on the third sidewall 7123, the first air outlet 7141 on the first sidewall 7121, and the second air outlet 7142 may not be arranged on the second sidewall 7122; or the air inlet 713 may be arranged on the third sidewall 7123, the second air outlet 7142 on the second sidewall 7122, and the first air outlet 7141 may not be arranged on the first sidewall 7121. Furthermore, in other embodiments, the air inlets and air outlets may also be arranged at different positions on the same sidewall. For example, the air inlet may be arranged on the upper part of the sidewall and the air outlet on the lower part of the sidewall, or the air inlet may be arranged on the left side of the sidewall and the air outlet on the right side of the sidewall. Those skilled in the art should understand that the positions of the air inlet and air outlet are not limited to those listed above.

[0159] In one embodiment, see Figure 2A At least one of the multiple sidewalls has no air inlet or outlet on its centerline extending along the channel direction, and the distance between the centerline of this sidewall and the centerline of the channel is the shortest. Preferably, no air inlet or outlet is provided within 2-50mm on either side of the centerline extending along the channel direction of each sidewall.

[0160] Reference Figure 2AThe sidewalls for providing air inlets, such as the third sidewall 7123, are provided with multiple air inlets 713; the sidewalls for providing air outlets, such as the first sidewall 7121 and the second sidewall 7122, are provided with multiple air outlets 714. The multiple air inlets 713 are evenly arranged in two rows along the axial direction on the third sidewall 7123, the multiple first air outlets 7141 are evenly arranged in two rows along the axial direction on the first sidewall 7121, and the multiple second air outlets 7142 are evenly arranged in two rows along the axial direction on the second sidewall 7122. Preferably, the two rows of air inlets and / or outlets are respectively arranged on both sides of the centerline of the side wall. For example, a plurality of first air inlets 7141 are arranged in two rows and are located on both sides of the centerline of the first side wall 7121 at a certain distance. It is preferable that the two rows of first air inlets 7141 are arranged symmetrically with respect to the centerline of the first side wall 7121. In other embodiments, the plurality of air inlets and / or outlets can also be arranged in one or more rows along the axial direction. The air inlets and / or outlets can also be arranged on the side wall in a non-uniform manner. In this embodiment, a plurality of air inlets 713 are arranged axially from one end of the third sidewall 7123 to the other end of the third sidewall 7123, a plurality of first air outlets 7141 are arranged axially from one end of the first sidewall 7121 to the other end of the first sidewall 7121, and a plurality of second air outlets 7142 are arranged axially from one end of the second sidewall 7122 to the other end of the second sidewall 7122. In other embodiments, the air inlets or outlets may also be distributed axially on a portion of the sidewall according to the actual air intake or exhaust requirements.

[0161] Figure 2B yes Figure 2A A C-direction view of the electric field element, as shown Figure 2B As shown, the center of the air inlet 713 and the center of the air outlet 714 are arranged on different planes perpendicular to the axial direction. That is, the line connecting the center of the air inlet 713 and the center of the air outlet 714 is not perpendicular to the axial direction. This structure causes gas to enter the internal channel of the electric field unit 710 through the air inlet 713 when it is not parallel to the sidewall of the electric field unit. The gas cannot be directly discharged through the air outlet, resulting in turbulent gas flow, increasing the residence time in the channel, and even forming a cyclone-like gas flow, before being discharged from the electric field unit 710 through the air outlet 714. In this embodiment, the center of the air inlet 713 and the centers of the first air outlet 7141 and the second air outlet 7142 are arranged on different planes perpendicular to the axial direction. The centers of the first air outlet 7141 and the second air outlet 7142 can be arranged on the same plane perpendicular to the axial direction or on different planes perpendicular to the axial direction. When there are multiple air inlets 713 and air outlets 714, preferably, the center of any air inlet and the center of any air outlet are arranged on different planes perpendicular to the axial direction.

[0162] Reference Figure 2BThe air inlet 713 and the air outlet 714 are circular holes of the same diameter. However, in other embodiments, the air inlet and the air outlet can be elliptical holes, triangular holes, quadrilateral holes, or pentagonal holes; the diameters of the air inlet and the air outlet can also be different, but it is necessary to ensure that the gas cannot be discharged directly through the air outlet without obstruction. That is, if the two sidewalls are overlapped, the air inlet and the air outlet will not completely overlap or one air inlet / air outlet will completely contain the other air outlet or air inlet, so that the gas will encounter obstruction when flowing, so that the airflow changes direction and forms a cyclone path in the channel when it flows in through the air inlet and out through the air outlet, and then is discharged from the electric field unit through the air outlet.

[0163] In one embodiment, the ratio of the total area of ​​the air inlets or outlets on a sidewall to the total area of ​​the sidewall is less than or equal to a certain value. After extensive experimentation and in-depth research, the inventors unexpectedly discovered that setting the total area of ​​the air inlets or outlets on a sidewall to be less than or equal to 49% of the total area of ​​the sidewall—preferably within the range of 40%-49%, and more preferably equal to 49%—increases ventilation while maximizing the strength and rigidity of the sidewall.

[0164] In one embodiment, the sidewall is made of a conductive material, such as a material containing stainless steel and / or aluminum. Preferably, the use of aluminum has the advantage of low energy consumption.

[0165] Figure 3 This is a top cross-sectional view of an electric field device according to an embodiment of the present invention. The electric field device 700 includes a discharge electrode 719 and an adsorption electrode 710. The adsorption electrode 710 is composed of an electric field unit. In this embodiment, the adsorption electrode 710 can also be referred to as an electric field unit 710. The electric field unit is the same as that described above and will not be repeated. This embodiment only describes the differences.

[0166] like Figure 3As shown, the channel 711 of the electric field unit 710 is provided with a discharge electrode 719. In this embodiment, the cross-section of the channel 711, which is surrounded by sidewalls and perpendicular to the axial direction, is an equilateral triangle. The discharge electrode 719 is preferably arranged parallel to the sidewalls of the channel and passes through the center of the inscribed circle of the cross-section, where the discharge efficiency is highest. However, in other embodiments, the cross-section of the channel, which is surrounded by sidewalls and perpendicular to the axial direction, can be other polygons. The discharge electrode is arranged parallel to the sidewalls of the channel and passes through the center line of the channel. The center line is a line extending along the axial direction of the channel and passing through the midpoint of the polygonal cross-section. For example, when the cross-section of the channel, which is surrounded by sidewalls and perpendicular to the axial direction, is rectangular, the center line is a line extending along the axial direction of the channel and passing through the intersection of the long side symmetry axis and the short side symmetry axis of the rectangular cross-section. When the cross-section of the channel, which is surrounded by sidewalls and perpendicular to the axial direction, is triangular, the center line is a line extending along the axial direction of the channel and passing through the intersection of the angle bisectors of the triangular cross-section. Preferably, when the channel, surrounded by sidewalls, has a regular polygonal cross-section perpendicular to the axial direction, the discharge electrode is arranged parallel to the sidewalls of the channel and passes through the center of the inscribed circle of the cross-section. Those skilled in the art will understand that, due to limitations in actual processing conditions, the discharge electrode may be arranged slightly off-center from the centerline of the channel or the center of the inscribed circle of the cross-section.

[0167] In this embodiment, the discharge electrode 719 is an elongated 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 719 is 0.1-10 mm, preferably 0.2-5 mm.

[0168] In one embodiment, the discharge electrode 719 is elongated and made of any one of 304 stainless steel, titanium, tungsten, or iridium. Preferably, the discharge electrode is made of iridium.

[0169] Reference Figure 3The electric field unit 710 is electrically connected to one electrode of the power supply, and the discharge electrode 719 is electrically connected to the other electrode of the power supply. The electric field unit 710 and the discharge electrode 719 form an active electric field. Preferably, the electric field unit 710 is electrically connected to the anode of the power supply, and the discharge electrode 719 is electrically connected to the cathode of the power supply, that is, the electric field unit 710 is the anode and the discharge electrode 719 is the cathode. However, in other embodiments, the electric field unit 710 may also be electrically connected to the cathode of the power supply, and the discharge electrode 719 may be electrically connected to the anode of the power supply, that is, the electric field unit 710 is the cathode and the discharge electrode 719 is the anode. When the electric field unit 710 is electrically connected to the anode of the power supply and the discharge electrode 719 is electrically connected to the cathode of the power supply, gas enters in a direction not parallel to the sidewall of the electric field unit 710. The discharge electrode 719 discharges and ionizes, causing the particulate matter in the gas to acquire a negative charge. The negatively charged particulate matter moves towards the electric field unit 710 and deposits on the electric field unit 710. When the center of the air inlet and the center of the air outlet on the side wall of the electric field unit 710 are arranged on different planes perpendicular to the axial direction, the gas flow in the channel 711 can be disordered, which further increases the residence time of the gas in the channel 711 and increases the frequency of close contact with the discharge electrode 719. The closer to the discharge electrode 719, the higher the gas ionization efficiency, thereby improving the charging efficiency and charge of particulate matter. Moreover, when the gas forms a cyclone flow, it is conducive to the separation of large particles. Combining the above two points, the dust removal efficiency is effectively improved.

[0170] Figure 4A This is a three-dimensional schematic diagram of an electric field device according to an embodiment of the present invention. The electric field device 80 includes a discharge electrode and an adsorption electrode. In this embodiment, the similarities between the adsorption electrode and the discharge electrode and those described above will not be repeated. This embodiment only describes the differences.

[0171] Reference Figure 4AThe adsorption electrode is composed of an electric field adsorption device 800. The electric field adsorption device 800 includes eight electric field units, namely a first electric field unit 810, a second electric field unit 820, a third electric field unit 830, a fourth electric field unit 840, a fifth electric field unit 850, a sixth electric field unit 860, a seventh electric field unit 870, and an eighth electric field unit 880. The eight electric field units are arranged adjacently on the left and right sides, and adjacent electric field units share a sidewall. The channel of each electric field unit is surrounded by the sidewall, and the cross-section perpendicular to the axial direction is an equilateral triangle. In other embodiments, the number of electric field units in the electric field adsorption device is not limited to this. The number of electric field units can be adjusted according to the actual gas flow rate to be purified. Moreover, the multiple electric field units can be arranged adjacently and / or non-adjacently in any direction, such as up, down, left, right, front, or back. In this embodiment, the eight electric field units have the same structure and shape for ease of production and processing. However, in other embodiments, depending on the storage conditions of the device space or other factors, the structure, shape, and size of the multiple electric field units may be different or partially the same.

[0172] Reference Figure 4A The discharge electrode 809 includes a first discharge electrode 819, a second discharge electrode 829, a third discharge electrode 839, a fourth discharge electrode 849, a fifth discharge electrode 859, a sixth discharge electrode 869, a seventh discharge electrode 879, and an eighth discharge electrode 889. Each discharge electrode is disposed within the channel of its corresponding electric field unit. Since the cross-section of the channel of each electric field unit, formed by the sidewalls surrounding it, is an equilateral triangle perpendicular to the axial direction, the discharge electrode 809 is preferably disposed parallel to the sidewall of the channel and passes through the center of the inscribed circle of the corresponding electric field unit's cross-section, where the discharge efficiency is highest. For example, the first discharge electrode 819 is disposed within the channel of the first electric field unit 810, and is preferably disposed parallel to the sidewall of the channel and passes through the center of the inscribed circle of the first electric field unit 810's cross-section, and so on, relating the other discharge electrodes to the electric field units.

[0173] Reference Figure 4AThe structure of the first electric field unit 810 and the second electric field unit 820 will be used as examples for explanation, and the structures of other electric field units can be deduced by analogy. The first electric field unit 810 includes a first channel 811 extending along the axial direction, and a side wall 812 is formed around the first channel 811. The side wall 812 is provided with a first air inlet 813 for gas to enter the channel 811 and a first air outlet 814 for gas to exit the first channel 811. There are multiple first air inlets 813 and first air outlets 814. Multiple first air inlets 813 are evenly arranged in two rows along the axial direction on the first side wall 8121, and multiple first air outlets 814 are evenly arranged in two rows along the axial direction on the second side wall 8122. There are no air inlets or air outlets distributed on the third side wall 8123. The center of the first air inlet 813 and the center of the first air outlet 814 are arranged on different planes perpendicular to the axial direction. The first electric field unit 810 and the second electric field unit 820 share a second sidewall 8122. The two surfaces of the second sidewall 8122 face the first channel 811 of the first electric field unit 810 and the second channel 821 of the second electric field unit 820, respectively. That is, the first vent 814 on the second sidewall 8122 of the first electric field unit 810 is used as the second vent of the second sidewall 8122 of the second electric field unit 820 to ensure that gas can directly enter the second electric field unit 820 from the first electric field unit 810. Multiple second vents 824 are opened on the fourth sidewall 8222 of the second electric field unit 820 and are evenly arranged in two rows along the axial direction. No vents and / or vents are opened on the fifth sidewall 8223 of the second electric field unit 820.

[0174] Reference Figure 4AIn this embodiment, all electric field units are electrically connected to the same pole of the power supply, and all discharge electrodes are electrically connected to the other pole of the power supply. For example, taking the first electric field unit 810 and the second electric field unit 820 as examples, the first electric field unit 810 is electrically connected to the anode of the power supply, and the first discharge electrode 819 is electrically connected to the cathode of the power supply; the second electric field unit 820 is electrically connected to the anode of the power supply, and the second discharge electrode 829 is electrically connected to the cathode of the power supply. The first electric field unit 810 and the first discharge electrode 819 form a first electric field, and the second electric field unit 820 and the second discharge electrode 829 form a second electric field. However, in other embodiments, multiple electric field units are divided into two groups, and the two groups of electric field units are arranged in two or more rows. Each row of electric field units is in the same group. The first group of electric field units is electrically connected to the anode of the power supply, and the corresponding first group of discharge electrodes is electrically connected to the cathode of the power supply; the second group of electric field units is electrically connected to the cathode of the power supply, and the corresponding second group of discharge electrodes is electrically connected to the anode of the power supply. When the airflow passes through the electric fields formed by the first set of electric field units and the first set of discharge electrodes, and the electric fields formed by the second set of electric field units and the second set of discharge electrodes, the particulate matter in the gas acquires negative and positive charges respectively. The negatively charged particulate matter in the gas is deposited on the first set of electric field units, and the particulate matter in the gas that is easily charged with positive charges is deposited on the second set of electric field units, thereby improving the dust removal efficiency.

[0175] Reference Figure 4ATaking the gas flow of the first electric field unit 810 and the second electric field unit 820 as an example, the gas flow of other electric field units follows the same principle. Gas enters the first electric field through the first inlet 813, then enters the second electric field through the first outlet 814, and finally exits through the second outlet 824. Since the centers of the first inlet 813 and the first outlet 814 are arranged on different planes perpendicular to the axial direction, and the centers of the second inlet (in this embodiment, the second inlet is the first outlet 814) and the second outlet 824 are arranged on different planes perpendicular to the axial direction, the gas flow is turbulent as it passes through the first and second electric fields, further increasing the residence time of the gas in the two electric fields and increasing the frequency of close contact with the first discharge electrode 819 and the second discharge electrode 829. The closer to the discharge electrode 809, the higher the gas ionization efficiency, improving the particulate matter charging efficiency and charge. Moreover, when the gas forms a cyclone flow, it is beneficial for the separation of large particles. Combining the above two points, the dust removal efficiency is effectively improved. In other embodiments, an air inlet is provided on the fifth sidewall 8223 of the second electric field unit 820, so that the airflow between the second electric field unit 820 and the third electric field unit 830 is connected, and gas can flow from the third electric field unit 830 to the second electric field unit 820. However, in other embodiments, an air inlet or outlet can be provided on the sidewall of each electric field unit, resulting in gas in each electric field unit originating from or flowing to multiple adjacent electric field units. The gas flow is highly turbulent, and more airflow passes near the discharge electrode, increasing the charge efficiency and charge of the particles in the gas, thereby improving the dust removal efficiency.

[0176] Figure 5 This is a front view schematic diagram of an electric field device including a top plate and a bottom plate. The electric field device 80 also includes a top plate 81 and a bottom plate 82. The top plate 81 and the bottom plate 82 are respectively connected to the two ends of the electric field adsorption device 800, that is, respectively connected to the two ends of each electric field unit in the electric field adsorption device 80, and the two ends are sealed to ensure that gas only enters and exits through the air inlet or outlet of each electric field unit. It should be noted that the top plate 81 and the bottom plate 82 are only for the convenience of description and are not intended to restrict their orientation. That is, the top plate 81 does not need to be located at the top, and the bottom plate 82 does not need to be located at the bottom. Specifically, they can be set at both ends of the electric field adsorption device 800 according to the placement orientation of the electric field device 80, so as to seal the channel of each electric field unit.

[0177] Figure 6This is an exploded cross-sectional view of an electric field unit assembly according to an embodiment of the present invention. The electric field unit assembly 900 includes an electric field unit 910 and an auxiliary adsorption mechanism 920. The electric field unit 910 has an axially extending channel 911, and a sidewall 912 is formed around the channel 911. The sidewall 912 is provided with an inlet for gas to enter the channel and an outlet for gas to exit the channel. The auxiliary adsorption mechanism 920 has a porous structure and is arranged on one side of at least a portion of the sidewall 912 of the electric field unit 910. The at least a portion is provided with an inlet and / or an outlet. The electric field unit is the same as described above and will not be repeated. This embodiment only describes the differences.

[0178] Reference Figure 6 The sidewall 912 of the electric field unit 910 includes an inner surface 9121 and an outer surface 9122. In this embodiment, the auxiliary adsorption mechanism 920 is preferably arranged on one side of the sidewall 912 where the electric field unit 910 has an inlet and / or outlet. The gas passes through the sidewall 912 of the electric field unit 910 in a manner that is not parallel to the sidewall 912 of the electric field unit 910. The porous auxiliary adsorption mechanism 920 can filter out a portion of the particles in the gas at the inlet and outlet ends through physical filtration. In other embodiments, the auxiliary adsorption mechanism can also be arranged on a portion of the inner and / or outer surface of the sidewall of the electric field unit where the inlet and / or outlet are located. In this embodiment, there is a gap between the auxiliary adsorption mechanism 920 and the electric field unit 910. Preferably, the distance between the auxiliary adsorption mechanism 920 and the electric field unit 910 is less than or equal to 50 mm. The gas in this space will mix again, and the mixed gas will then be used for particle removal by the electric field unit 910 or the auxiliary adsorption mechanism 920. Within a certain distance range between the auxiliary adsorption mechanism 920 and the electric field unit 910, the charge of the auxiliary adsorption mechanism 910 increases with the increase of the distance between them. In other embodiments, the auxiliary adsorption mechanism 920 is adhesively attached to the entire outer surface 9122 of the side wall 912 of the electric field unit 910. This attachment can be understood as theoretically having no gap between the auxiliary adsorption mechanism 920 and the electric field unit 910. In other embodiments, the attachment method can also be selected from tenon and mortise fixing, riveting fixing, or other mechanical fixing methods. Tenon and mortise fixing can be achieved by first fixing the auxiliary adsorption mechanism to the frame, and then fixing the frame to the electric field unit with tenon and mortise. However, those skilled in the art will understand that due to the limitations of actual processing conditions, there may be a certain gap when the auxiliary adsorption mechanism 920 is attached to the side wall 912 of the electric field unit 910. This gap can be ignored.

[0179] Reference Figure 6In this embodiment, the auxiliary adsorption mechanism 920 is composed of a 60-mesh polytetrafluoroethylene (PTFE) film. Since PTFE is an electret material, after the electret material is charged by an electric field, its own electret electric field can electrostatically adsorb charged particles. Moreover, when the electric field suddenly disappears, the electret electric field will not disappear, and dust removal can continue. In other embodiments, the pore size of the auxiliary adsorption mechanism can also be selected from one or more of 40-100 mesh. The finer the pore size, the greater the air resistance and the greater the energy consumption. Preferably, the pore size of the auxiliary adsorption mechanism can also be selected from one or more of 40-80 mesh; it can also be composed of multiple layers of thin films, with the porous structure overlapping and interconnected. In other embodiments, the material of the auxiliary adsorption mechanism may be selected from one or more of conductive materials or electret materials, wherein the conductive material may be selected from one or more of metals or alloys, and the electret material may be selected from inorganic compounds with electret properties and / or organic compounds with electret properties. 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. The organic compound is selected from one or more combinations of fluorocarbon polymers, polycarbonate, polypropylene, polyethylene, polyvinyl chloride, natural wax, resin, and rosin. The fluorocarbon polymer is selected from one or more combinations of polytetrafluoroethylene, polyvinylidene fluoride, perfluoroethylene propylene, soluble perfluoroethylene propylene, and soluble polytetrafluoroethylene.

[0180] One embodiment of the present invention provides an electric field unit component. The electric field adsorption component is the same as that described above and will not be repeated. This embodiment only describes the differences.

[0181] The electric field adsorption assembly includes an electric field unit and an auxiliary adsorption mechanism. The electric field unit has an inlet for gas entry and / or an outlet for gas exit. The auxiliary adsorption mechanism has a porous structure and is arranged on one side of at least a portion of the sidewall of the electric field unit, wherein the at least a portion has the inlet and / or outlet. Preferably, there is a gap between the auxiliary adsorption mechanism and at least a portion of the electric field unit. More preferably, the distance between the auxiliary adsorption mechanism and at least a portion of the electric field unit is less than or equal to 50 mm, allowing the gas in this space to mix again. The mixed gas then passes through the electric field unit or the auxiliary adsorption mechanism for particle removal. Within a certain distance range between the auxiliary adsorption mechanism and the electric field unit, the charge of the auxiliary adsorption mechanism increases with the increase of the distance between them. In other embodiments, the auxiliary adsorption mechanism may also be attached to at least a portion of the surface of the sidewall of the electric field unit.

[0182] The electric field unit can be plate-shaped, serving as one pole to form the electric field. It has an inner surface facing the other pole and an outer surface opposite the inner surface. The auxiliary adsorption mechanism is arranged on one side of the outer surface of the plate-shaped electric field unit. Preferably, the plate-shaped electric field unit serves as the anode to form the electric field. Gas passes through the electric field unit in a manner not parallel to its sidewalls. The porous auxiliary adsorption mechanism can filter out some particles from the gas at the inlet and outlet ends through physical filtration. When the auxiliary adsorption mechanism is made of electret material, after the electric field charges the electret material, its own electret electric field can electrostatically adsorb charged particles. Furthermore, even if the electric field suddenly disappears, the electret electric field will not disappear, allowing dust removal to continue.

[0183] Figure 7 This is an exploded perspective view of an electric field adsorption device according to an embodiment of the present invention. The electric field adsorption device 1000 includes eight electric field units and an auxiliary adsorption mechanism 1020. Each electric field unit has an axially extending channel, and a sidewall 1010 is formed around the channel.

The electric field units, auxiliary adsorption mechanism, and electric field adsorption device are the same as described above and will not be repeated. This embodiment only describes the differences.

[0184] The sidewall 1010 of the electric field adsorption device 1000 includes a first type of sidewall 1011 and a second type of sidewall 1012. A channel is arranged on one side of the first type of sidewall 1011, and a channel is arranged on each side of the second type of sidewall 1012. The first type of sidewall 1011 has an inner surface facing the channel and an outer surface opposite to the inner surface.

In this embodiment, the auxiliary adsorption mechanism 1020 is arranged on one side of at least a portion of the outer surface of the first type of sidewall 1011, and there is a gap between the auxiliary adsorption mechanism 1020 and the outer surface of the first type of sidewall 1011. Preferably, the distance between the auxiliary adsorption mechanism 1020 and the outer surface of the first type of sidewall 1011 is less than or equal to 50 mm. The gas in this space will be remixed, and the mixed gas will then be used for particle removal by the electric field unit or the auxiliary adsorption mechanism. Within a certain distance range between the auxiliary adsorption mechanism and the electric field unit, the charge of the auxiliary adsorption mechanism increases with the increase of the distance between them. In other embodiments, the auxiliary adsorption mechanism 1020 is arranged to conform to at least a portion of the outer surface of the first type of sidewall 1011. In this embodiment, the electric field adsorption device has 10 first type of sidewalls 1011, of which 8 are provided with air inlets and / or outlets, and the 8 auxiliary adsorption mechanisms 1020 are respectively arranged on one side of the outer surface of the 8 first type of sidewalls 1011 provided with air inlets and / or outlets.

In other embodiments, the auxiliary adsorption mechanism is arranged to conform to at least a portion of the surface of the second type of sidewall.

[0185] Figure 8 This is an exploded perspective view of an electric field adsorption device according to an embodiment of the present invention. The electric field adsorption device 1100 includes 12 electric field units and an auxiliary adsorption mechanism 1120. In other embodiments, the electric field adsorption device 1100 may also include only 12 electric field units. Each electric field unit has an axially extending channel, with a sidewall 1110 forming around the channel. The sidewall 1110 is provided with an inlet for gas to enter the channel and an outlet for gas to exit the channel. The auxiliary adsorption mechanism 1120 has a porous structure and is arranged on one side of at least a portion of at least one sidewall 1110 of at least one electric field unit. The at least one portion is provided with the inlet or outlet. The auxiliary adsorption mechanism 1120 is made of a 60-mesh polytetrafluoroethylene film. The electric field units, auxiliary adsorption mechanism, and electric field adsorption device are the same as described above and will not be repeated. This embodiment only describes the differences.

[0186] The sidewall 1110 of the electric field adsorption device 1100 includes a first type of sidewall 1111 and a second type of sidewall 1112. A channel is arranged on one side of the first type of sidewall 1111, and a channel is arranged on each side of the second type of sidewall 1112. The first type of sidewall 1111 has an inner surface facing the channel and an outer surface opposite to the inner surface. An auxiliary adsorption mechanism 1120 is arranged on one side of the outer surface of the first type of sidewall 1111. In this embodiment, the auxiliary adsorption mechanism 1120 is arranged on at least a portion of one side of the outer surface of the first type of sidewall 1111, and there is a gap between the auxiliary adsorption mechanism 1120 and the outer surface of the first type of sidewall 1111. Preferably, the auxiliary adsorption mechanism 1120 is arranged on at least a portion of one side of the outer surface of the first type of sidewall 1111, and there is a distance of less than or equal to 50 mm between the auxiliary adsorption mechanism 1120 and the outer surface of the first type of sidewall 1111. The gas in this space will be mixed again, and the mixed gas will then be used for particle removal by the electric field unit or the auxiliary adsorption mechanism. Within a certain distance range between the auxiliary adsorption mechanism and the electric field unit, the charge of the auxiliary adsorption mechanism increases with the increase of the distance between them. In other embodiments, the auxiliary adsorption mechanism 1120 is arranged to adhere to at least a portion of the outer surface of the first type of sidewall 1111. In this embodiment, two auxiliary adsorption mechanisms 1120 are arranged integrally on one side of the outer surface of the first type of sidewall 1111, which has an air inlet or outlet. In other embodiments, the auxiliary adsorption mechanism may also be disposed on one side of at least a portion of the surface of the second type of sidewall. Preferably, there is a gap between the auxiliary adsorption mechanism and the surface of the second type of sidewall; more preferably, the distance between the auxiliary adsorption mechanism and the surface of the second type of sidewall is less than or equal to 50 mm. In other embodiments, the auxiliary adsorption mechanism is arranged to adhere to at least a portion of the surface of the second type of sidewall.

[0187] One embodiment of the present invention provides an electric field device, including a discharge electrode and an adsorption electrode. The adsorption electrode is composed of the electric field adsorption component described in the above embodiment. The electric field adsorption component is the same as described above and will not be repeated here; only the differences are described in this embodiment. The discharge electrode can be composed of a long, thin or flat conductor and is arranged on one side of the flat adsorption electrode. When the discharge electrode is a flat conductor, the sidewall of the discharge electrode can be provided with multiple pores to allow gas flow. In other embodiments, the adsorption electrode can also be composed of an electric field unit assembly with a polygonal cross-section perpendicular to the axial direction, formed by the channel of the electric field unit in the above embodiments being surrounded by sidewalls. The discharge electrode is arranged parallel to the sidewall of the channel and passes through the center line of the channel. The center line is a line extending along the axial direction of the channel and passing through the midpoint of the polygonal cross-section. For example, when the cross-section of the channel surrounded by sidewalls perpendicular to the axial direction is rectangular, the center line is a line extending along the axial direction of the channel and passing through the intersection of the long side symmetry axis and the short side symmetry axis of the rectangular cross-section; when the cross-section of the channel surrounded by sidewalls perpendicular to the axial direction is triangular, the center line is a line extending along the axial direction of the channel and passing through the intersection of the angle bisectors of the triangular cross-section; preferably, when the cross-section of the channel surrounded by sidewalls perpendicular to the axial direction is a regular polygon, the discharge electrode is arranged parallel to the sidewall of the channel and passes through the center of the inscribed circle of the cross-section, where the discharge efficiency is the highest.

[0188] The adsorption electrode is electrically connected to one pole of the power supply, and the discharge electrode is electrically connected to the other pole. Preferably, the adsorption electrode is electrically connected to the anode of the power supply, and the discharge electrode is electrically connected to the cathode of the power supply. The adsorption electrode and the discharge electrode form an electric field. Gas enters in a direction not parallel to the sidewall of the adsorption electrode. Some particles in the gas are filtered by an auxiliary adsorption mechanism arranged on the sidewall with the air inlet before entering the electric field. The particles entering the electric field gain a negative charge due to ionization discharge. The negatively charged particles move towards the adsorption electrode and are deposited on the adsorption electrode. Particles not adsorbed by the electric field can also be filtered by the auxiliary adsorption mechanism arranged on the sidewall with the air outlet after leaving the electric field, thus improving dust removal efficiency. When the auxiliary adsorption mechanism is made of electret material, after the electric field charges the electret material, the electret electric field of the electret material itself can electrostatically adsorb the charged particles. Moreover, when the electric field suddenly disappears, the electret electric field does not disappear, and dust removal can continue.

[0189] One embodiment of the present invention provides an electric field device, including a discharge electrode and an adsorption electrode. The adsorption electrode is composed of the electric field adsorption device described in the above embodiment. The similarities between the electric field adsorption device and the electric field device are not repeated here; only the differences are described in this embodiment. The discharge electrode is disposed within the channel of each electric field unit in the electric field adsorption device. Preferably, when the cross-section of the channel, formed by the sidewalls, perpendicular to the axial direction, is a regular polygon, the discharge electrode is arranged parallel to the sidewalls of the channel and passes through the center of the inscribed circle of the cross-section, where the discharge efficiency is highest. When the material of the auxiliary adsorption mechanism is 60-mesh polytetrafluoroethylene, the porous material auxiliary adsorption mechanism can filter out some particles in the gas at the inlet and outlet ends through physical filtration. Furthermore, after the electric field charges the electret material, the electret electric field of the electret material itself can electrostatically adsorb charged particles. Compared to the case without an auxiliary adsorption mechanism, the dust removal efficiency is improved by 10-20%. Since polytetrafluoroethylene is an electret material, when the active electric field suddenly disappears, the electret electric field of the auxiliary adsorption mechanism can also remove dust. Experiments show that when the active electric field of the electric field adsorption device suddenly disappears, the dust removal efficiency can reach 30% by using only the auxiliary adsorption mechanism.

[0190] In one embodiment, refer to Figure 4B The electric field adsorption device 800 is formed by connecting multiple electric field units through connectors. In this embodiment, the electric field adsorption device 800 is formed by connecting eight electric field units. Specifically, the electric field adsorption device 800 is generally composed of two rows of electric field units. For ease of description, these rows will be referred to as... Figure 4BUsing the directions shown as a reference, the row with the sidewalls facing downwards is called the first row, and the row with the sidewalls facing upwards is called the second row. The first row is formed by connecting a first electric field unit 810, a third electric field unit 830, a fifth electric field unit 850, and a seventh electric field unit 870 of identical size and structure sequentially through their respective bottom sidewalls, with the axes of their channels parallel to each other and on the same plane. The second row is formed by connecting a second electric field unit 820, a fourth electric field unit 840, a sixth electric field unit 860, and an eighth electric field unit 880 of identical size and structure sequentially through their respective top sidewalls. Specifically, in this embodiment, the bottom sidewalls of the first electric field unit 810, the third electric field unit 830, the fifth electric field unit 850, and the seventh electric field unit 870 are each provided with a folded edge. The folded edges on the bottom sidewalls of each pair of adjacent electric field units are aligned with each other. By connecting a connector to the folded edge, the two adjacent electric field units are fixedly connected. For example, the folded edges of the two adjacent electric field units are riveted together using rivets to fix them together. Riveting not only facilitates processing but also provides good sealing. Riveting not only ensures a good seal between the connected sidewalls but also allows the rivet to expand within the rivet hole during riveting, resulting in a high sealing performance between the rivet and the hole. Similarly, the second electric field unit 820, the fourth electric field unit 840, the sixth electric field unit 860, and the eighth electric field unit 880 also have folded edges on their top sidewalls. The folded edges of two adjacent electric field units are aligned with each other, and the adjacent electric field units are fixedly connected by connecting the connectors to the folded edges. Specifically, the connection method of adjacent electric field units is illustrated by taking the connection method of the first electric field unit 810, the third electric field unit 830, and the fifth electric field unit 850 in the first row as an example. The bottom sidewall of the third electric field unit 830 has a downwardly bent first folded edge 891, and the bottom sidewall of the first electric field unit 810 has a downwardly bent second folded edge 892. The first folded edge 891 and the second folded edge 892 are aligned with each other. The first electric field unit 810 and the third electric field unit 830 are fixedly connected by passing a connector through the first folded edge 891 and the second folded edge 892. The bottom sidewall of the third electric field unit 830 has a downwardly bent second folded edge 893, and the bottom sidewall of the fifth electric field unit 850 has a downwardly bent first folded edge 894. The third electric field unit and the fifth electric field unit are fixedly connected by passing a connector through the first folded edge 894 and the second folded edge 893. In this embodiment, the first folded edges of each of the multiple electric field units and the second folded edges of adjacent units are preferably riveted together. The connection method between the fifth electric field unit 850 and the seventh electric field unit 870 is similar and will not be described in detail.

[0191] Continue to refer to Figure 4BIn this embodiment, the first electric field unit 810 and the second electric field unit 820 share a second sidewall 8122. That is, the two sides of the second sidewall 8122 face the channels of the first electric field unit 810 and the second electric field unit 820, respectively. The upper and lower ends of the second sidewall 8122 are respectively provided with an upper folded edge 895 and a lower folded edge 896. The upper folded edge 895 and the lower folded edge 896 are bent in different directions. The two sides of the upper folded edge 895 are aligned with the folded edges of the third sidewall 8123 of the first electric field unit 810 and the fourth sidewall 8222 of the second electric field unit 820, and are fixedly connected by connectors such as rivets. The fourth sidewall 8222 of the second electric field unit 820 is connected to the first electric field unit 810 and the third electric field unit 830. The fourth sidewall 8222, the second sidewall 8122, and the fifth sidewall 8223 constitute the second electric field unit 820.

[0192] Similarly, multiple electric field units are connected in the manner described above to form an electric field adsorption device 800. It should be noted that, in Figure 4B In the illustrated embodiment, each sidewall of each electric field unit has a folded edge at both ends perpendicular to the axial direction. The same electric field unit is fixedly connected by the folded edges of adjacent sidewalls. Different electric field units are connected by sharing a sidewall and fixing their other sidewalls to the shared sidewall. For example, the second sidewall 8122 shared by the first electric field unit 810 and the second electric field unit 820 is simultaneously fixedly connected to the third sidewall 8123 of the first electric field unit 810 and the fourth sidewall 8222 of the second electric field unit 820.

[0193] It should be noted that, in Figure 4B In the illustrated embodiment, the folded edges of the top sidewall (e.g., the fourth sidewall 8222) and the bottom sidewall (e.g., the first sidewall 8121) are bent approximately perpendicular to the main body of their respective sidewalls, while the folded edge of the middle sidewall (e.g., the second sidewall 8122) connecting the top and bottom sidewalls is bent approximately at a 120-degree angle to the main body of its respective sidewall. This arrangement facilitates the stable placement of the electric field adsorption device and allows for multi-layer stacking.

[0194] Figure 9A An electric field adsorption device 1100 according to an embodiment of the present invention is shown. (Refer to...) Figure 9AThe electric field adsorption device 1100 includes 12 identical electric field units, from left to right: second electric field unit 620, first electric field unit 610, third electric field unit 630, fourth electric field unit 640, fifth electric field unit 650, sixth electric field unit 660, seventh electric field unit 670, eighth electric field unit 680, ninth electric field unit 690, tenth electric field unit 691, eleventh electric field unit 692, and twelfth electric field unit 693. The 12 identical electric field units are arranged adjacent to each other, with adjacent units sharing a sidewall. The channel of each electric field unit is surrounded by the sidewall, forming a regular hexagonal cross-section perpendicular to the axial direction. In other embodiments, the number of electric field units in the electric field adsorption device is not limited to this; the number of electric field units can be adjusted according to the actual required gas flow rate. Furthermore, the multiple electric field units can be arranged adjacently and / or non-adjacently in any direction (up, down, left, right, front, back). In this embodiment, the twelve electric field units have the same structure and shape for ease of production and processing. However, in other embodiments, depending on the storage conditions of the device space or other factors, the structure, shape, and size of the multiple electric field units may be different or partially the same.

[0195] Figure 9B yes Figure 9A Top view, refer to Figure 9B In this embodiment, the first electric field unit 610 is arranged adjacent to the second electric field unit 620 and the third electric field unit 630. The first electric field unit 610 is formed by a first side wall 611, a second side wall 612, a third side wall 613, a fourth side wall 614, a fifth side wall 615, and a sixth side wall 616, and its cross-section is a regular hexagon. Each side wall is provided with multiple air inlets and / or air outlets. The first electric field unit 610 and the second electric field unit 620 share the first side wall 613 of the first electric field unit 610, and the first electric field unit 610 and the third electric field unit 630 share the fifth side wall 615 of the first electric field unit 610.

[0196] exist Figure 9A and 9B In the illustrated embodiment, no air inlet or outlet is provided along the centerline of each sidewall extending in the channel direction of each electric field unit. Specifically, taking the first electric field unit 610 as an example, no air inlet or outlet is provided on the centerline 617 of each sidewall of the first electric field unit 610, thereby forming a dust accumulation portion at the position of the sidewall centerline. When the discharge electrode is set at the centerline of the channel of the electric field unit, the distance between the discharge electrode and the centerline of the sidewall is the shortest distance between the discharge electrode and the sidewall, thus the dust collection efficiency of this part is the highest, and the best dust collection effect can be achieved.

[0197] It should be noted that, although Figure 9AIn the illustrated embodiment, no air inlet or outlet is provided along the centerline of each sidewall of each electric field unit. However, it is also possible to omit air inlet or outlet only along the centerline portion of one or more sidewalls of one or more electric field units. Although these cases do not have the same effect... Figure 9A The illustrated embodiment is excellent, but it also has certain technical effects. Compared with the scheme of setting an air inlet or outlet at the center line position, the absence of an air inlet or outlet at the center line can achieve higher efficiency in dust accumulation.

[0198] Furthermore, it should be noted that the centerline in this invention refers to the centerline extending along the channel direction on the sidewall, and the distance between the centerline and the two ends of the sidewall where the centerline is located perpendicular to the channel is equal.

[0199] Figure 10 This is a three-dimensional schematic diagram of an electric field device according to an embodiment of the present invention. The electric field device includes a discharge electrode and an adsorption electrode.

[0200] In this embodiment, the electric field device includes multiple discharge electrodes and adsorption electrodes. The discharge electrodes include a first discharge electrode 619, a second discharge electrode 629, a third discharge electrode 639, a fourth discharge electrode 649, and eight other discharge electrodes. The adsorption electrodes are... Figure 9A and Figure 9B The electric field adsorption device 1100 shown contains multiple electric field units with identical structures. The adsorption electrode reference... Figure 9A and Figure 9B The description of the electric field adsorption device shown is not detailed here. Figure 10 As shown, no air inlet or outlet is provided on the portion of each sidewall of each electric field unit at the shortest distance 617 from the discharge electrode. For example, when the cross-section of the channel of the electric field unit perpendicular to the axis is a regular polygon, no air inlet or outlet is provided on the centerline of each sidewall (e.g.). Figure 9A and 9B (The electric field adsorption device shown). For example, no air inlet or outlet is provided on the part of each side wall of the first electric field unit 610 that is closest to the discharge electrode 619, so that the part becomes a dust accumulation part.

[0201] Reference Figure 10 The first discharge electrode 619 is disposed in the channel of the first electric field unit 610, and a first electric field is formed between the first discharge electrode 619 and the first electric field unit 610. The second electric field unit 620, the third electric field unit 630, and the fourth electric field unit 640 form a second electric field, a third electric field, and a fourth electric field with the second discharge electrode 629, the third discharge electrode 639, and the fourth discharge electrode 649, respectively. And so on, the remaining electric field units form an electric field with a discharge electrode.

[0202] Since the channel of each electric field unit has a regular hexagonal cross-section perpendicular to the axial direction formed by the sidewalls surrounding it, the discharge electrode is preferably arranged parallel to the sidewall of the channel and passes through the center of the inscribed circle of the corresponding electric field unit cross-section, where the discharge efficiency is highest. For example, the first discharge electrode 619 is disposed in the channel of the first electric field unit 610, and is preferably arranged parallel to the sidewall of the channel and passes through the center of the inscribed circle of the first electric field unit 610 cross-section, and so on for the relationship between other discharge electrodes and electric field units.

[0203] Reference Figure 9B , Figure 10 In this embodiment, A is the air inlet direction and B is the air outlet direction. The case of gas flowing in the first, second, and third electric fields is used as an example for explanation, and the case of other electric fields is deduced by analogy.

[0204] For the first electric field, gas enters the first electric field unit 610 through the air inlets on the first sidewall 611, second sidewall 612, and sixth sidewall 616. The gas entry direction is not perpendicular to the ion flow direction within the first electric field. Because the air inlets on the first sidewall 611, second sidewall 612, and sixth sidewall 616 are staggered with the air outlets on the third sidewall 613, fourth sidewall 614, and fifth sidewall 615, the gas flow can reach multiple adjacent electric field units. The gas flow within the hollow electric field unit 610 is turbulent, resulting in more particles passing near the first discharge electrode 619, more collisions with the discharge electrode 619, and more charged particles, thus improving adsorption efficiency. Furthermore, because the first electric field has two inclined planes, the inclined air inlet further turbulents the gas flow within the hollow first electric field unit 610. Increased collisions with the sidewalls further increase the frequency of passing near the first discharge electrode 619, resulting in even higher adsorption efficiency. After being processed by the first electric field, the gas is discharged through the vents on the third side wall 613, the fourth side wall 614, and the fifth side wall 615, and then enters the second and third electric fields through the vents on the third side wall 613 and the fifth side wall 615.

[0205] For the second electric field, a portion of the gas enters through the inlet holes on the fourth sidewall 624 and fifth sidewall 625 of the adsorption unit 620, while another portion of the gas from the first electric field enters through the hole on the third sidewall 613 of the first electric field unit 610. The direction of these gases entering is not perpendicular to the direction of the ion flow within the second electric field. Due to the staggered arrangement of the inlet and outlet holes, the airflow within the hollow electric field unit 620 is turbulent. The more airflow passes near the discharge electrode 629, the more collisions occur between particles and the second discharge electrode 629, resulting in more charged particles and improved adsorption efficiency. Furthermore, since the second electric field also has an inclined plane, the inclined airflow further turbulents the airflow within the hollow second electric field unit 620, leading to even higher adsorption efficiency. After treatment by the second electric field, the gas is discharged through the outlet holes on the first sidewall 621, second sidewall 622, and third sidewall 623 of the second electric field unit 620.

[0206] For the third electric field, a portion of the gas enters the third electric field through the inlet hole on the fifth sidewall 635 of the third electric field unit 630, while another portion enters the third electric field through the hole on the fifth sidewall 615 of the first electric field unit 610 (gas from the first electric field) and the hole on the fourth sidewall 634 of the third electric field unit 630 (gas from the fourth electric field). The direction of these gases entering is not perpendicular to the direction of the ion flow within the third electric field. Due to the staggered arrangement of the inlet and outlet holes, the airflow within the hollow third electric field unit 630 is turbulent. The more airflow passes near the discharge electrode 639, the more particles collide with the third discharge electrode 639, resulting in more charged particles and improved adsorption efficiency. After treatment by the third electric field, the gas is discharged through the outlet holes on the first sidewall 631, second sidewall 632, and third sidewall 633 of the third electric field unit 630.

[0207] Similarly, the process of gas entering other electric field generating units can be deduced from this.

[0208] The electric field unit of the electric field device in this embodiment has a structure with holes in the side wall. The side air intake makes the gas flow turbulent in the electric field, increasing the collision with the third discharge electrode 639, increasing the number of charged particles, and improving the overall adsorption efficiency.

[0210] Figure 12 yes Figure 11 A three-dimensional exploded diagram.

This at least a portion has the inlet and / or outlet. The auxiliary adsorption element is made of a 60-mesh polytetrafluoroethylene film. The electric field units, auxiliary adsorption elements, and electric field adsorption device are the same as described above and will not be repeated here; this embodiment only describes the differences.

[0212] In one embodiment, the electric field adsorption device includes a plurality of electric field units, a plurality of connecting members, and at least one auxiliary adsorption element, the auxiliary adsorption element being arranged on at least a portion of the outer surface of the sidewall.

[0213] In one embodiment, the electric field adsorption device includes a plurality of electric field units, a plurality of connecting members, and at least one auxiliary adsorption element. The auxiliary adsorption element is arranged on at least a portion of the outer surface of the sidewall, and there is a gap between the auxiliary adsorption element and the surface of the electric field unit.

[0214] In one embodiment, the auxiliary adsorption element is made of a 60-mesh polytetrafluoroethylene film.

[0215] In one embodiment, the connecting member is any one or a combination of an elastic member, a connecting assembly, and a clip.

[0216] In one embodiment, the connecting component includes a rivet or a bolt.

[0217] In one embodiment, the electric field unit has multiple sidewalls, each sidewall having a bent edge at both ends. The bent edges of two adjacent sidewalls in the electric field unit are connected to form a connecting end. The bent edges of two adjacent electric field units are aligned sequentially to form a unit connecting end. Two adjacent electric field units are connected at the unit connecting end. The auxiliary adsorption component is disposed on the outside of the unit connecting end. The multiple bent edges and the auxiliary adsorption component in the unit connecting end are connected and fixed by rivets.

[0218] In one embodiment, the electric field adsorption device further includes a gasket disposed between the rivet and the auxiliary adsorption element.

[0219] Preferably, the gasket has an L-shaped cross-section.

[0220] In one embodiment, such as Figure 11 , 12As shown, the electric field adsorption device 1200 includes 6 electric field units, 12 gaskets 500, multiple rivets 99 and two auxiliary adsorption components 1220.

[0221] In one embodiment, refer to Figure 4B , Figure 11 The six electric field units include the first electric field unit 810, the second electric field unit 820, the third electric field unit 830, the fourth electric field unit 840, the fifth electric field unit 850, and the sixth electric field unit 860.

[0222] For ease of description, Figure 11 Using the directions shown as a reference, the row with sidewalls facing downwards is called the first row, and the row with sidewalls facing upwards is called the second row. The first row is formed by connecting first electric field units 810, third electric field units 830, and fifth electric field units 850 of identical size and structure sequentially through their respective bottom sidewalls, with the axes of their channels parallel to each other and on the same plane. The second row is formed by connecting second electric field units 820, fourth electric field units 840, and sixth electric field units 860 of identical size and structure sequentially through their respective top sidewalls. Specifically, in this embodiment, the bottom sidewalls of the first electric field units 810, third electric field units 830, and fifth electric field units 850 are provided with folded edges, and the folded edges on the bottom sidewalls of every two adjacent electric field units are aligned with each other. The top sidewalls of the second electric field units 820, fourth electric field units 840, and sixth electric field units 860 are also provided with folded edges.

[0223] Specifically, the connection point D between the first electric field unit 810 and the third electric field unit 830 in the first row is used as an example to illustrate the connection method between the electric field unit and the auxiliary adsorption mechanism 1020 through the gasket 500.

[0224] The bottom sidewall of the third electric field unit 830 is provided with a first folded edge 891 that bends downwards, and the bottom sidewall of the first electric field unit 810 is provided with a second folded edge 892 that bends downwards. The upper and lower ends of the second sidewall 8122 are provided with an upper folded edge 895 and a lower folded edge 896, respectively, and the upper folded edge 895 and the lower folded edge 896 bend in different directions. The upper and lower ends of the fifth sidewall 8223 are provided with an upper folded edge 897 and a lower folded edge 898, respectively, and the upper folded edge 895 and the lower folded edge 896 bend in different directions.

[0225] Reference Figure 12At connection point D, from left to right, the second folded edge 892 of the bottom sidewall of the first electric field unit 810, the lower folded edge 896 of the second sidewall 8122, the lower folded edge 898 of the fifth sidewall 8223, and the first folded edge 891 of the bottom sidewall of the third electric field unit 830 are aligned with each other and connected by connecting members such as rivets. In this embodiment, the connecting members include rivets and gaskets. An auxiliary adsorption member 1220 is disposed between the first folded edge 891 or the second folded edge 892 and the gasket.

[0226] The folded edges and auxiliary adsorption components of two adjacent electric field units are riveted together to fix them in place. Riveting not only facilitates processing but also provides excellent sealing. The riveting not only ensures a good seal between the connected sidewalls but also, as the rivet expands within its hole during riveting, it creates a high level of sealing between the rivet and the hole.

[0227] In this embodiment, the gasket 500 is a straight strip with an "L" shaped cross-section. At the connection point D, the two gaskets 500 are respectively arranged on the first folded edge 891 and the second folded edge 892 along the axial direction of the channel. The first right-angled side (parallel to the first folded edge 891) clamps the auxiliary adsorption member 1220 with the first folded edge 891 or the second folded edge 892, and the second right-angled side (perpendicular to the first folded edge 891) clamps the auxiliary adsorption member 1220 with the side wall at the bottom of the electric field unit.

[0228] Similarly, multiple electric field units, multiple gaskets, multiple rivets, and two auxiliary adsorption components are connected in the manner described above to form an electric field adsorption device 1200.

[0229] In one embodiment, during assembly, the first right-angled side of the gasket (parallel to the first folded edge 891) clamps the auxiliary adsorption member 1220 with either the first folded edge 891 or the second folded edge 892, and the second right-angled side is at a distance from the sidewall of the bottom of the electric field unit. At ends D and E, the auxiliary adsorption member 1220 is fixed to the first right-angled side of the two gaskets via the first folded edge 899 and the second folded edge 892 of the bottom sidewall of the first electric field unit 810, respectively. When the auxiliary adsorption member 1220 is tightened, the second right-angled side abuts against and adheres tightly to the auxiliary adsorption member 1220, so that there is a certain distance between the auxiliary adsorption member 1220 and the outer surface of the sidewall 8121. Preferably, the auxiliary adsorption member 1220 is arranged on at least a portion of the outer surface of the sidewall 8121 and the distance between the auxiliary adsorption member 1220 and the outer surface of the sidewall 8121 is less than or equal to 50 mm. The gases in this space will mix again, and the mixed gases will then be used for particle removal by the electric field unit or the auxiliary adsorption mechanism. Within a certain distance range between the auxiliary adsorption element and the electric field unit, the charge on the auxiliary adsorption element increases as the distance between them increases.

[0230] In one embodiment, the gasket is sheet-shaped. During assembly, one side of the gasket clamps the auxiliary adsorption member 1220 with the first folded edge 891 or the second folded edge 892, and one long side of the gasket is in close contact with the side wall surface at the bottom of the electric field unit.

[0232] In one embodiment, such as Figure 13 As shown, the inner cross-section of the clip 501 is groove-shaped. The clip 501 is fitted onto multiple folded parts of the connecting end to fix the multiple folded parts of the connecting end and the auxiliary adsorption component 1220. During assembly, the inner cross-section of the clip 501 matches and is tightly fitted with the thickness of the folded parts and the thickness of the auxiliary adsorption component 1220. The open end 5011 of the clip 501 is in close contact with the side wall surface at the bottom of the electric field unit.

[0233] In one embodiment, during assembly, the open end 5011 of the clip 501 has a gap with the side wall surface at the bottom of the electric field unit.

[0234] In one embodiment, the card 501 can be configured in multiple segments, but preferably, the card 501 is a single unit.

[0235] In one embodiment, the elastic member 502 has an opening and is fitted on the outside of the folded edge of the connecting end to fix multiple folded edges of the connecting end and the auxiliary adsorption member 1220, thereby clamping and fixing the multiple folded edges and the auxiliary adsorption member 1220 by elasticity.

[0236] Better, such as Figure 14 As shown, the elastic element 502 has a gasket 5021 at its open end.

[0237] Preferably, the gasket can be configured in multiple segments.

[0238] Preferably, the gasket is a single piece.

[0239] In one embodiment, the gasket 5021 is sheet-shaped. During assembly, one side of the gasket clamps the auxiliary adsorption member 1220 with the first folded edge 891 or the second folded edge 892, and one long side 5022 of the gasket is in close contact with the side wall surface at the bottom of the electric field unit.

[0240] In one embodiment, during assembly, one long side 5022 of the gasket has a gap with the side wall surface at the bottom of the electric field unit.

[0241] In one embodiment, such as Figure 15 As shown, the gasket 503 is L-shaped. During assembly, the first right-angled surface of the gasket clamps the auxiliary adsorption component 1220 with the first folded edge 891 or the second folded edge 892, and the second right-angled surface 5031 of the gasket is in close contact with the side wall surface at the bottom of the electric field unit.

[0242] In one embodiment, during assembly, the second face 5031 of the right angle of the gasket has a gap with the side wall surface at the bottom of the electric field unit.
