Description

Technical Field

[0001] This application relates to, but is not limited to, the field of air purification technology, specifically to an electrostatic dust collection net, a dust collection device, and an air handling equipment. Background Technology

[0002] In related technologies, dust collection devices include a frame, multiple first dust collection plates, and multiple second dust collection plates. The multiple first dust collection plates and multiple second dust collection plates need to be manually inserted and fixed onto the frame one by one, resulting in low production efficiency. Utility Model Content

[0003] The technical problem to be solved by this application is to provide an electrostatic dust collection net, a dust collection device, and an air handling equipment, which is beneficial to improving the production efficiency of the dust collection device.

[0004] This application provides an electrostatic dust collection mesh, comprising: multiple first electrode layers, multiple second electrode layers, and a continuously bent insulating sheet; the multiple first electrode layers are configured to connect to the high-voltage end of a power supply module, and the multiple second electrode layers are configured to connect to the low-voltage end or ground end of the power supply module; the insulating sheet includes an air duct component and two connecting portions, the two connecting portions being located on both sides of the air duct component along a first direction and connected to the air duct component; the first electrode layers and the second electrode layers are alternately spaced along a second direction perpendicular to the first direction in the air duct component, the air duct component having multiple first cut-off portions spaced along the second direction and extending along the first direction, the first... A cut-off portion is located between adjacent first electrode layers and second electrode layers, so that an air passage can be formed between any adjacent first electrode layers and second electrode layers; the center line of the first cut-off portion extending along the first direction is the bending line of the insulating sheet; a plurality of second cut-off portions are provided between the air duct forming portion and each of the connecting portions, and both ends of each first cut-off portion in the first direction are connected to the second cut-off portion, and the length L1 of the second cut-off portion in the second direction in the flat state is greater than the width L3 of the first cut-off portion in the second direction in the flat state, so that the first electrode layer and the second electrode layer can be parallel to each other.

[0005] The electrostatic dust collection mesh provided in this application embodiment, through the arrangement of continuously bent insulating sheets, a first cut-off portion, and a second cut-off portion, achieves a parallel and spaced distribution of the first and second electrode layers and provides an air passage. Furthermore, due to the presence of the two connecting portions, the electrostatic dust collection mesh forms an integrated structure, rather than being multiple dispersed dust collection sheets. Therefore, it does not require individual insertion and fixing; instead, it can be installed as a whole on the frame, thereby improving the production efficiency of the dust collection device.

[0006] By setting a second cutting section, the electrostatic precipitator can be continuously bent along the centerline of each first cutting section, making the first electrode layer and the second electrode layer parallel to each other. This is beneficial for the uniform distribution of the electric field between the first and second electrode layers, as well as for reducing wind resistance, increasing ventilation volume, and thus improving dust removal efficiency. Furthermore, fewer bending operations simplify the production process, thereby improving production efficiency. The spacing between the first and second electrode layers is also relatively small. Under the same conditions of total airflow area and power supply voltage, this solution is beneficial for increasing the strength of the dust collection electric field and the number of dust collection plates, thus improving dust removal efficiency.

[0032] The principles and features of this application are described below with reference to the accompanying drawings. The examples given are only for explaining this application and are not intended to limit the scope of this application.

[0033] like Figure 1 and Figure 2 As shown, this application embodiment provides an electrostatic dust collection mesh 100, including: a plurality of first electrode layers 21, a plurality of second electrode layers 22, and a continuously bent insulating sheet 1.

[0034] Multiple first electrode layers 21 are configured to connect to the high-voltage end of a power supply module (not shown in the figure), and multiple second electrode layers 22 are configured to connect to the low-voltage end or ground end of the power supply module. The power supply module can be a DC power supply module. The voltage output from the high-voltage end of the power supply module can be negative high voltage or positive high voltage, the voltage output from the low-voltage end can be positive high voltage or negative high voltage (but the absolute value of the voltage is lower than the absolute value of the voltage output from the high-voltage end), and the voltage output from the ground end is 0. Therefore, the dust collection sheet formed by the first electrode layer 21 and its corresponding insulating sheet 1 can be called a high-voltage dust collection sheet, and the dust collection sheet formed by the second electrode layer 22 and its corresponding insulating sheet 1 can be called a low-voltage dust collection sheet (or a grounded dust collection sheet, hereinafter collectively referred to as a low-voltage dust collection sheet).

[0035] like Figure 1 As shown, the insulating sheet 1 includes an air duct component 15 and two connecting portions 16. The two connecting portions 16 are located on both sides of the air duct component 15 along a first direction and are connected to the air duct component 15. The first direction is the extending direction of the dust collection sheet, which is also the width direction of the insulating sheet 1.

[0036] The first electrode layer 21 and the second electrode layer 22 are alternately spaced along a second direction perpendicular to the first direction in the air duct forming part 15. The second direction is the length direction of the insulating sheet 1. The air duct forming part 15 is provided with a plurality of first cut-off portions 13 spaced along the second direction and extending along the first direction. The first cut-off portions 13 are located between adjacent first electrode layers 21 and second electrode layers 22, so that an air passage can be formed between any adjacent first electrode layers 21 and second electrode layers 22. The center line of the first cut-off portion 13 extending along the first direction is the bending line 17 of the insulating sheet 1. The insulating sheet 1 can be continuously bent along the center line of the plurality of first cut-off portions 13 to form a sawtooth-like structure. After bending, an air passage opening will be formed at the location of the first cut-off portion 13, so that an air passage with the airflow direction perpendicular to the first and second directions can be formed between adjacent first electrode layers 21 and second electrode layers 22.

[0037] like Figure 1 As shown, a plurality of second cut-off portions 14 are provided between the air duct component 15 and each connecting portion 16, spaced apart along the second direction. Both ends of each first cut-off portion 13 in the first direction are connected to the second cut-off portion 14, and the length L1 of the second cut-off portion 14 in the second direction when it is laid flat is greater than the width L3 of the first cut-off portion 13 in the second direction when it is laid flat, so that the first electrode layer 21 and the second electrode layer 22 can be parallel to each other.

[0038] Without the second cutting section 14, when bending directly along the center line of the first cutting section 13, the first electrode layer 21 and the second electrode layer 22 would form an acute angle due to the restriction of the connecting sections 16 on both sides, making it difficult for them to be parallel. This would affect the uniform distribution of the electric field between the first electrode layer 21 and the second electrode layer 22, and would also generate greater wind resistance, reducing ventilation volume and thus reducing dust removal efficiency.

[0039] After the addition of the second cutting section 14, the connection between the first cutting section 13 and the connecting sections 16 on both sides is broken. When bending along the center line of the first cutting section 13, the part where the first cutting section 13 is located can get rid of the restriction of the connecting sections 16 on both sides. After bending, it can open to form a wider air passage opening. The width of the air passage opening is determined by the length L1 of the second cutting section 14, rather than by the width L3 of the first cutting section 13. This makes the distance between the first electrode layer 21 and the second electrode layer 22 larger, so that they can be parallel to each other. This is beneficial to the uniform distribution of the electric field between the first electrode layer 21 and the second electrode layer 22, as well as to reduce wind resistance, increase ventilation volume, and thus improve dust removal efficiency.

[0040] In a comparative example, by eliminating the second cut-off portion 14 and providing bending lines 17 on both sides of the width direction of each first cut-off portion 13, the first electrode layer 21 and the second electrode layer 22 are made parallel by two 90° bends. However, a relatively large interval is required between the two bending lines 17 to achieve parallelism between the first electrode layer 21 and the second electrode layer 22. (Ignoring the thickness of the insulating sheet 1, the distance between the two bending lines 17 is equal to the distance between the first electrode layer 21 and the second electrode layer 22). Compared with the above comparative example, this solution only requires one bend along the center line of the first cut-off portion 13 between adjacent first electrode layers 21 and second electrode layers 22, thus reducing the number of bends by half, simplifying the production process, and improving production efficiency. Furthermore, the distance between the first electrode layer 21 and the second electrode layer 22 is significantly reduced. Under the same conditions of total air passage area and power supply voltage of the electrostatic dust collection mesh 100, this solution is beneficial to increasing the strength of the dust collection electric field and the number of dust collection plates, thereby improving dust removal efficiency.

[0041] Therefore, the electrostatic dust collection mesh 100 provided in this embodiment achieves parallel and spaced distribution of the first electrode layer 21 and the second electrode layer 22 with air passages through the continuously bent insulating sheet 1, the first cut-off portion 13, and the second cut-off portion 14. Furthermore, due to the presence of the two connecting portions 16, the electrostatic dust collection mesh 100 forms an integrated structure, no longer consisting of multiple dispersed dust collection sheets. Therefore, it does not require individual insertion and fixing; instead, it can be installed as a whole on the frame 4, thereby improving the production efficiency of the dust collection device.

[0042] By setting the second cutting section 14, the electrostatic dust collection mesh 100 can be continuously bent along the center line of each first cutting section 13, so that the first electrode layer 21 and the second electrode layer 22 are parallel to each other. This is beneficial to the uniform distribution of the electric field between the first electrode layer 21 and the second electrode layer 22, as well as to reduce wind resistance, increase ventilation volume, and thus improve dust removal efficiency. Moreover, the number of bending times is less, which helps to simplify the production process and thus improve production efficiency. It also makes the distance between the first electrode layer 21 and the second electrode layer 22 relatively small. Under the same conditions of total air passage area and power supply voltage of electrostatic dust collection mesh 100, this solution is beneficial to increase the strength of the dust collection electric field and the number of dust collection plates, thereby improving dust removal efficiency.

[0043] In some exemplary embodiments, such as Figure 1 As shown, the second cutting section 14 is symmetrically arranged about the center line of the first cutting section 13 that is connected to it.

[0044] In this way, after the insulating sheet 1 is bent along the center line of the first cut portion 13, the first cut portion 13 can open to both sides and extend two symmetrical and parallel extension portions 18, such as... Figure 2 As shown, the space between the two extensions 18 is the air passage opening, and the width of the air passage opening is determined by the length L1 of the second cut-off portion 14. The width L4 of the extension 18 is (L1-L3) / 2.

[0045] The first electrode layer 21 and the second electrode layer 22 can extend to the locations of the two extension portions 18, which helps to increase the area of ​​the dust collection electric field and improve dust removal efficiency. Of course, the first electrode layer 21 and the second electrode layer 22 may not extend to the locations of the two extension portions 18.

[0046] In some exemplary embodiments, such as Figure 2 As shown, the portion of the first electrode layer 21 and the insulating sheet 1 corresponding to the first electrode layer 21 forms the first dust collection sheet 23 (i.e., the high-voltage dust collection sheet). The portion of the second electrode layer 22 and the insulating sheet 1 corresponding to the second electrode layer 22 forms the second dust collection sheet 24 (i.e., the low-voltage dust collection sheet). The distance d between adjacent first dust collection sheets 23 and second dust collection sheets 24 is d = (2 × L1) / π.

[0047] Since the adjacent first electrode layer 21 and second electrode layer 22 only undergo one bend, the second cut portion 14 and the connecting portion 16 outside the second cut portion 14 will bend to form a semicircle. Therefore, the distance between the adjacent first dust collecting plate 23 and second dust collecting plate 24 is the diameter d of this semicircle, so d = (2 × L1) / π. Therefore, by adjusting the length L1 of the second cut portion 14, the distance between the first dust collecting plate 23 and the second dust collecting plate 24 can be adjusted.

[0048] exist Figure 2 , Figure 4 and Figure 5 In order to clearly illustrate the first dust collection plate 23, the second dust collection plate 24 and the air passage, the distance between the first dust collection plate 23 and the second dust collection plate 24 has been enlarged. In fact, the distance between the first dust collection plate 23 and the second dust collection plate 24 is very small, and the dust collection plates are arranged relatively densely.

[0049] In some exemplary embodiments, such as Figure 1 and Figure 4 As shown, the electrostatic dust collection mesh 100 also includes a first electrical connection strip 31 and a second electrical connection strip 32 extending along a second direction. The first electrical connection strip 31 is disposed at one of the connection portions 16 and connected to a plurality of first electrode layers 21, and the second electrical connection strip 32 is disposed at the other connection portion 16 and connected to a plurality of second electrode layers 22.

[0050] In this way, by connecting the first electrical connection strip 31 and the second electrical connection strip 32 to the high-voltage terminal and low-voltage terminal (or ground terminal) of the power supply module, respectively, the power supply module can simultaneously supply power to multiple first electrode layers 21 and multiple second electrode layers 22, without requiring each first electrode layer 21 to be electrically connected to the power supply module separately, nor does it require each second electrode layer 22 to be electrically connected to the power supply module separately. This simplifies the wiring process of the electrostatic dust collection mesh 100 and also helps to improve production efficiency.

[0051] The semi-circular portion of the connecting part 16, which is bent into a semi-circular shape, and the semi-circular structure formed by the first electrical connection strip 31 and the second electrical connection strip 32 located at that portion, can be referred to as the bent connecting strip 25. The first dust collecting plate 23 and the second dust collecting plate 24 are located between adjacent bent connecting strips 25.

[0052] In some exemplary embodiments, such as Figure 3 As shown, the insulating sheet 1 includes a first insulating layer 11 and a second insulating layer 12. A plurality of first electrode layers 21 and a plurality of second electrode layers 22 are sandwiched between the first insulating layer 11 and the second insulating layer 12.

[0053] In this way, on the one hand, it helps to reduce the risk of electric shock to users, thereby improving the safety of using the electrostatic dust collection net 100; on the other hand, it can also protect the first electrode layer 21 and the second electrode layer 22, which helps to extend the service life of the electrostatic dust collection net 100.

[0054] The material of the first insulating layer 11 / second insulating layer 12 can be, but is not limited to, modified PET (Polyethylene Terephthalate).

[0055] In some exemplary embodiments, the second cut-off portion 14 is configured as a strip-shaped notch, such as... Figure 1 As shown. In other words, the second cut-off portion 14 can form a strip-shaped notch by cutting off a portion of the insulating sheet 1, which can then be bent and deformed.

[0056] In some exemplary embodiments, the width L2 of the strip notch in the first direction is greater than or equal to 0.1 mm in the flat state to ensure the feasibility of industrial production.

[0057] In some exemplary embodiments, the first cut-off portion 13 is configured as a strip-shaped opening, such as... Figure 1 As shown. In other words, the first cut-off portion 13 can form a strip-shaped opening by cutting off a portion of the insulating sheet 1, which can be opened to form a ventilation opening during subsequent bending.

[0058] In some exemplary embodiments, the width L3 of the strip opening in the second direction is greater than or equal to 0.1 mm in the flat state to ensure the feasibility of industrial production.

[0059] In some other exemplary embodiments, the first cutting portion 13 is configured as a first strip-shaped cut. In other words, the first cutting portion 13 can make a cut without removing material, which can reduce waste and help reduce production costs.

[0060] In some exemplary embodiments, the second cutting portion 14 is configured as a second strip-shaped cut. In other words, the second cutting portion 14 can make a cut without removing material, which can reduce waste and help reduce production costs.

[0061] In some exemplary embodiments, such as Figure 4 As shown, the first direction is the width direction of the electrostatic precipitator 100, and the second direction is the length direction of the electrostatic precipitator 100. The first electrode layer 21 and the second electrode layer 22 are conductive graphite layers. The first electrical connection strip 31 and the second electrical connection strip 32 are good conductor layers. The electrostatic precipitator 100 is usually installed at the return air vent of the air handling equipment, and the return air vent is usually rectangular, such as... Figure 5 As shown.

[0062] Therefore, the extension direction of the first dust collecting plate 23 / second dust collecting plate 24 is consistent with the short side direction of the return air inlet, and the extension direction of the first electrical connection strip 31 / second electrical connection strip 32 is consistent with the long side direction of the return air inlet. Compared to the first dust collecting plate 23 / second dust collecting plate 24 having its extension direction consistent with the long side direction of the return air inlet, the extension direction of the first electrical connection strip 31 / second electrical connection strip 32 having its extension direction consistent with the short side direction of the return air inlet, this scheme is beneficial to fully utilize the conductivity efficiency of good conductors, reduce the voltage loss of conductive graphite, and improve the dust removal efficiency by more than 30%.

[0063] Furthermore, the first dust collection plate 23 / the second dust collection plate 24 form a stable cross structure with the long side frame 4, making the overall structure more stable.

[0064] This application also provides a preparation method for preparing the electrostatic dust collection net 100 as described in any of the above embodiments, comprising the following steps:

[0065] Prepare the first insulating layer 11 in a flat state;

[0066] A first electrode layer 21 and a second electrode layer 22 are prepared on a first insulating layer 11 in a flat state;

[0067] Prepare a second insulating layer 12 in a flat state, and sandwich the first electrode layer 21 and the second electrode layer 22 between the first insulating layer 11 and the second insulating layer 12 to obtain a flat electrostatic dust collection net 100 blank.

[0068] A first cutting portion 13 and a second cutting portion 14 are processed on the flat electrostatic dust collection net 100 blank to obtain the flat electrostatic dust collection net 100.

[0069] The electrostatic dust collection net 100 in a flat state is continuously bent to obtain the electrostatic dust collection net 100.

[0070] In some exemplary embodiments, the preparation method further includes: preparing a first electrical connection strip 31 and a second electrical connection strip 32 on a first insulating layer 11 in a flat state. The preparation steps of the first electrical connection strip 31 and the second electrical connection strip 32 can be performed simultaneously with the preparation steps of the first electrode layer 21 and the second electrode layer 22.

[0071] The first insulating layer 11 and the second insulating layer 12 can be, but are not limited to, modified PET layers, and can be prepared using a laminating machine. The first electrode layer 21, the second electrode layer 22, the first electrical connection strip 31, and the second electrical connection strip 32 can be, but are not limited to, conductive graphite layers, conductive oil film layers, good conductor layers, etc., and can be prepared on the first insulating layer 11 by printing or deposition, and can be prepared using a printing machine or a deposition machine. The preparation steps of the first cut portion 13 and the second cut portion 14 can be achieved by a stamping machine. The bending step can be achieved by a bending machine or a machine tool.

[0072] Therefore, the electrostatic dust collection net 100 provided in this application embodiment can be industrialized, which is beneficial to improving production efficiency.

[0073] like Figure 4 and Figure 5 As shown, this application embodiment also provides a dust collection device, including: a frame 4 and an electrostatic dust collection net 100 as described in any of the above embodiments, which is installed on the frame 4.

[0074] The dust collection device provided in this application embodiment has all the above-mentioned beneficial effects because it includes the electrostatic dust collection net 100 of any of the above embodiments, and will not be repeated here.

[0075] In some exemplary embodiments, the dust collection device further includes a limiting structure 5, such as... Figure 5 As shown. The limiting structure 5 is connected to the electrostatic dust collection mesh 100 and is configured to maintain the spacing between adjacent first electrode layers 21 and second electrode layers 22.

[0076] This helps maintain the gap between the first electrode layer 21 and the second electrode layer 22, which not only helps to keep the dust collection electric field between them stable, but also helps to reduce wind resistance and increase air volume, thereby improving dust removal efficiency.

[0077] In some embodiments, the limiting structure 5 includes a comb-shaped retaining clip that is engaged with the electrostatic dust collection mesh 100 to maintain the spacing between adjacent first electrode layers 21 and second electrode layers 22. The teeth of the comb-shaped retaining clip can be clamped between adjacent first electrode layers 21 and second electrode layers 22 to maintain the spacing between the first electrode layers 21 and second electrode layers 22.

[0078] In other embodiments, the limiting structure 5 includes a fixing adhesive bonded within the air passage to maintain the spacing between adjacent first electrode layers 21 and second electrode layers 22. The fixing adhesive can be extruded between adjacent first electrode layers 21 and second electrode layers 22 in a liquid state, and after curing, it maintains the spacing between adjacent first electrode layers 21 and second electrode layers 22.

[0079] like Figure 5 As shown in the embodiments of this application, an air handling device is also provided, including a power supply module and a dust collection device as described in any of the above embodiments. The power supply module is electrically connected to a plurality of first electrode layers 21 and a plurality of second electrode layers 22, and is configured to supply power to the dust collection device.

[0080] The air handling equipment provided in this application includes the dust collection device of any of the above embodiments, and therefore has all the above-mentioned beneficial effects, which will not be repeated here.

[0081] The high voltage output by the power supply module to the first dust collecting plate 23 can be either negative or positive. The power supply module is configured to output DC high voltage (e.g., DC constant voltage high voltage) to the dust collection device, generating an electrostatic field between the first dust collecting plate 23 and the second dust collecting plate 24. This electrostatic field helps improve dust removal efficiency. Alternatively, the power supply module can also output pulsed high voltage to the dust collection device.

[0082] In some exemplary embodiments, the air handling equipment also includes a charging module (not shown) located upstream of the dust collection device. The charging module is configured to discharge to charge solid pollutants in the air. This makes it easier to capture charged solid pollutants as they flow towards the dust collection device, thereby improving purification efficiency.

[0083] In some exemplary embodiments, the charging module is also electrically connected to the power supply module. In other words, the power supply module supplies power to both the dust collection device and the charging module. This eliminates the need for a separate power supply module, simplifying the structure of the air handling equipment and reducing production costs.

[0084] In some embodiments, the power supply module includes components such as input terminals, input lines, high voltage transformers, charged output lines and carbon brush heads, dust collection output lines and terminals, and micro switches, and can simultaneously output the high voltage required by the charged module and the high voltage required by the dust collection device.

[0085] In some exemplary embodiments, the air handling device can be, but is not limited to, an air conditioner, an air purifier, a humidifier, a dehumidifier, or other air handling devices with air handling functions.

[0086] In some exemplary embodiments, the air handling equipment includes an air duct, and a dust collection device is disposed within the air duct, which may be located at the air inlet, the air outlet, or between the air inlet and the air outlet. The air handling equipment may also include a fan for promoting airflow within the air duct.

[0087] In one embodiment, such as Figure 5 As shown, the air handling unit is an air conditioner. The air conditioner includes an air conditioner body 6 and the aforementioned dust collection device. The air conditioner body 6 has a rectangular return air vent, and the dust collection device is located at the return air vent.

[0088] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0089] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
