Description

Technical Field

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

[0002] In related technologies, dust collection devices include a frame, multiple first electrode plates, and multiple second electrode plates. The multiple first electrode plates and multiple second electrode 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 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 a dust collection device, including: a frame and a first electrode module and a second electrode module mounted on the frame. The first electrode module is configured to connect to the high-voltage end of a power supply module, and the second electrode module is configured to connect to the low-voltage end or ground end of the power supply module. The first electrode module includes a plurality of spaced-apart first electrode plates and a first bent portion connecting two adjacent first electrode plates. The first bent portion is located on the same side of two adjacent first electrode plates and connected to one end of two adjacent first electrode plates. The second electrode module includes a plurality of spaced-apart second electrode plates and a second bent portion connecting two adjacent second electrode plates. The second bent portion is located on the same side of two adjacent second electrode plates and connected to one end of adjacent second electrode plates. The first bent portion and the adjacent second bent portion are spaced apart, and the second electrode plates and the first electrode plates are staggered along the thickness direction of the first electrode plates, so that a dust collection electric field can be formed between adjacent first electrode plates and second electrode plates.

[0005] The dust collection device provided in this application embodiment connects adjacent first electrode pieces into a whole through a first bending portion, and connects adjacent second electrode pieces into a whole through a second bending portion. Therefore, multiple first electrode pieces and multiple second electrode pieces are no longer multiple independent electrode pieces. They do not need to be manually inserted and fixed onto the frame one by one. It is only necessary to fix the first electrode module and the second electrode module onto the frame respectively, thereby reducing the assembly difficulty of the dust collection device and improving the production efficiency of the dust collection device.

[0006] Furthermore, multiple first electrode pieces can be electrically connected through the first bending portion, and multiple second electrode pieces can be electrically connected through the second bending portion. Therefore, as long as one of the first electrode module and the second electrode module has a power connection point connected to the power supply module, multiple first electrode pieces and multiple second electrode pieces can be powered.

[0007] Based on the above technical solution, the following improvements can be made to this application.

[0008] In an exemplary embodiment, the space between the first electrode sheet and the second electrode sheet forms an airflow channel. The width directions of the first electrode sheet, the second electrode sheet, the first bend, and the second bend are consistent with the airflow direction of the airflow channel. The width of the first bend is smaller than the width of the first electrode sheet, and the width of the second bend is smaller than the width of the second electrode sheet.

[0009] In an exemplary embodiment, the first bent portion is flush with one end of the width direction of the first electrode sheet, and the second bent portion is flush with the other end of the width direction of the second electrode sheet, so that adjacent first bent portions and second bent portions are staggered along the airflow direction of the airflow channel.

[0010] In one exemplary embodiment, the adjacent first bend and second bend are also staggered along the length direction of the first electrode sheet.

[0011] In an exemplary embodiment, the first bending portion includes a first extension segment, a first connecting segment, and a second extension segment connected in sequence. The first extension segment and the second extension segment are respectively connected to two adjacent first electrode sheets and extend along the length direction of the first electrode sheet. The first connecting segment extends along the thickness direction of the first electrode sheet. And / or, the second bending portion includes a third extension segment, a second connecting segment, and a fourth extension segment connected in sequence. The third extension segment and the fourth extension segment are respectively connected to two adjacent second electrode sheets and extend along the length direction of the second electrode sheet. The second connecting segment extends along the thickness direction of the second electrode sheet.

[0012] In one exemplary embodiment, the first electrode module is a bent-formed integral structure; and / or, the second electrode module is a bent-formed integral structure.

[0013] In an exemplary embodiment, a gap retainer is provided between adjacent first electrode plates and second electrode plates, the gap retainer being configured to maintain the gap between adjacent first electrode plates and second electrode plates.

[0014] In an exemplary embodiment, there are multiple gap retainers between adjacent first electrode plates and second electrode plates, and the multiple gap retainers are spaced apart along the length direction of the first electrode plate; and / or, the gap retainer includes a limiting post, the two ends of which are connected to adjacent first electrode plates and second electrode plates.

[0015] In an exemplary embodiment, there are multiple first electrode modules, and the first electrode plates of the multiple first electrode modules are arranged alternately; there are multiple second electrode modules, and the second electrode plates of the multiple second electrode modules are arranged alternately; the multiple first electrode modules and the multiple second electrode modules are interleaved and interposed, so that all the first electrode plates and all the second electrode plates are arranged alternately and interposed.

[0016] This application also provides an air handling device, 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 the first electrode module and the second electrode module and is configured to supply power to the dust collection device.

[0026] 40 limit post. Detailed Implementation

[0027] 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.

[0028] like Figures 1 to 4 As shown in the figure, this application provides a dust collection device, including: a frame 30 and a first electrode module 10 and a second electrode module 20 mounted on the frame 30. The first electrode module 10 is configured to connect to the high-voltage terminal of a power supply module, and the second electrode module 20 is configured to connect to the low-voltage terminal or ground terminal of the power supply module (not shown in the figure). The power supply module can be a DC power supply module. The voltage output from the high-voltage terminal of the power supply module can be negative high voltage, the voltage output from the low-voltage terminal can be positive high voltage (but the absolute value of the voltage is lower than the absolute value of the voltage output from the high-voltage terminal), and the voltage output from the ground terminal is 0. Therefore, the first electrode module 10 can be called a high-voltage module, and the second electrode module 20 can be called a low-voltage module (or ground module, hereinafter collectively referred to as low-voltage module).

[0029] like Figure 1 and Figure 2 As shown, the first electrode module 10 includes a plurality of spaced first electrode pieces 11 and a first bent portion 12 connecting two adjacent first electrode pieces 11. The first bent portion 12 is located on the same side of the two adjacent first electrode pieces 11 and is connected to one end of the two adjacent first electrode pieces 11.

[0030] like Figure 1 and Figure 2 As shown, the second electrode module 20 includes a plurality of spaced second electrode pieces 21 and a second bending portion 22 connecting two adjacent second electrode pieces 21. The second bending portion 22 is located on the same side of two adjacent second electrode pieces 21 and is connected to one end of the adjacent second electrode pieces 21.

[0031] like Figure 2 and Figure 4 As shown, the first bent portion 12 and the adjacent second bent portion 22 are spaced apart, and the second electrode plate 21 and the first electrode plate 11 are staggered along the thickness direction of the first electrode plate 11, so that a dust collection electric field can be formed between the adjacent first electrode plate 11 and the second electrode plate 21.

[0032] In the dust collection device provided in this application embodiment, adjacent first electrode plates 11 are connected into a whole through a first bending portion 12, and adjacent second electrode plates 21 are connected into a whole through a second bending portion 22. Therefore, multiple first electrode plates 11 and multiple second electrode plates 21 are no longer multiple independent electrode plates. They do not need to be manually inserted and fixed onto the frame 30 one by one. It is only necessary to fix the first electrode module 10 and the second electrode module 20 onto the frame 30 respectively, thereby reducing the assembly difficulty of the dust collection device and improving the production efficiency of the dust collection device.

[0033] Furthermore, multiple first electrode pieces 11 can be electrically connected through the first bending portion 12, and multiple second electrode pieces 21 can be electrically connected through the second bending portion 22. Therefore, as long as one of the first electrode module 10 and the second electrode module 20 is connected to the power supply module, multiple first electrode pieces 11 and multiple second electrode pieces 21 can be powered.

[0034] In some exemplary embodiments, the space between the first electrode sheet 11 and the second electrode sheet 21 forms an airflow channel. The width directions of the first electrode sheet 11, the second electrode sheet 21, the first bent portion 12, and the second bent portion 22 are consistent with the airflow direction of the airflow channel. Figure 2 As shown. In this way, the surfaces of the first bend 12 and the second bend 22 are aligned with the airflow direction, which can reduce the resistance of the first bend 12 and the second bend 22 to the airflow, which is beneficial to reducing the wind resistance of the dust collection device, increasing the air volume, and thus improving the dust removal efficiency of the dust collection device.

[0035] And, as Figure 2 As shown, the width of the first bent portion 12 is smaller than the width of the first electrode sheet 11, and the width of the second bent portion 22 is smaller than the width of the second electrode sheet 21. This facilitates the staggering of the first bent portion 12 and the second bent portion 22, avoiding contact between them, and effectively isolating the first electrode module 10 and the second electrode module 20.

[0036] In some exemplary embodiments, such as Figure 2 As shown, the first bent portion 12 is flush with one end of the first electrode sheet 11 in the width direction, and the second bent portion 22 is flush with the other end of the second electrode sheet 21 in the width direction, so that the adjacent first bent portions 12 and second bent portions 22 are staggered along the airflow direction of the airflow channel.

[0037] In this way, the first electrode module 10 and the second electrode module 20 can be formed by punching and bending the sheet conductor. The flush arrangement simplifies the punching process, thus facilitating the processing and forming of the first electrode module 10 and the second electrode module 20. The first bending portion 12 and the second bending portion 22 are located at opposite ends in the airflow direction, which facilitates the staggering of the first bending portion 12 and the second bending portion 22 in the airflow direction, thereby avoiding contact between the first bending portion 12 and the second bending portion 22 and effectively isolating the first electrode module 10 and the second electrode module 20.

[0038] In some exemplary embodiments, adjacent first bends 12 and second bends 22 are also staggered along the length of the first electrode sheet 11, such as... Figure 4 As shown.

[0039] This allows the first bent portion 12 and the second bent portion 22 to be staggered along the length of the first electrode sheet 11, so as to avoid contact between the first bent portion 12 and the second bent portion 22, which is beneficial to effectively isolate the first electrode module 10 and the second electrode module 20.

[0040] In some exemplary embodiments, such as Figure 1 As shown, the first bending portion 12 includes a first extension segment 121, a first connecting segment 123, and a second extension segment 122 connected in sequence. The first extension segment 121 and the second extension segment 122 are respectively connected to two adjacent first electrode sheets 11 and extend along the length direction of the first electrode sheet 11, and the first connecting segment 123 extends along the thickness direction of the first electrode sheet 11.

[0041] like Figure 1 As shown, the second bending portion 22 includes a third extension segment 221, a second connecting segment 223 and a fourth extension segment 222 connected in sequence. The third extension segment 221 and the fourth extension segment 222 are respectively connected to two adjacent second electrode sheets 21 and extend along the length direction of the second electrode sheet 21. The second connecting segment 223 extends along the thickness direction of the second electrode sheet 21.

[0042] This design facilitates the staggering of the first bending portion 12 and the second bending portion 22, preventing them from contacting each other and effectively isolating the first electrode module 10 and the second electrode module 20. Furthermore, it extends the length of the dust collection electric field region, thereby improving dust removal efficiency.

[0043] In some exemplary embodiments, the first electrode module 10 is a bent-formed integral structure. The second electrode module 20 is a bent-formed integral structure.

[0044] In this way, the first electrode module 10 can be integrally formed through a bending process, facilitating automated production. Similarly, the second electrode module 20 can be integrally formed through a bending process, facilitating automated production.

[0045] In some exemplary embodiments, such as Figure 4 As shown, a gap retainer is provided between adjacent first electrode plates 11 and second electrode plates 21, and the gap retainer is configured to maintain the gap between adjacent first electrode plates 11 and second electrode plates 21.

[0046] This helps maintain the gap between the first electrode plate 11 and the second electrode plate 21, 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.

[0047] In some exemplary embodiments, the number of gap retainers between adjacent first electrode plates 11 and second electrode plates 21 is multiple, such as... Figure 4 As shown, multiple gap retainers are spaced apart along the length of the first electrode sheet 11. This helps to improve the gap stability between adjacent first electrode sheets 11 and second electrode sheets 21.

[0048] Of course, the number of clearance retainers is not limited to the above scheme and can be adjusted as needed.

[0049] In some exemplary embodiments, the gap retainer includes a limiting post 40, such as Figure 4 As shown, the two ends of the limiting post 40 are connected to the adjacent first electrode sheet 11 and second electrode sheet 21. The limiting post 40 can be fixedly connected to the first electrode sheet 11 and second electrode sheet 21 by means of hot melt adhesive or double-sided adhesive. The limiting post 40 can be formed by fixing adhesive, which can be extruded between the adjacent first electrode sheet 11 and second electrode sheet 21 in a liquid state, and after curing, it forms the limiting post 40, maintaining the distance between the adjacent first electrode sheet 11 and second electrode sheet 21.

[0050] Of course, the gap retainer is not limited to the limiting post 40, but can also be a fixing clip, a limiting plate, a limiting block or other structural forms, as long as it can maintain the gap between the first electrode plate 11 and the second electrode plate 21.

[0051] In some exemplary embodiments, there are multiple first electrode modules 10, and the first electrode pieces 11 of the multiple first electrode modules 10 are arranged in a staggered manner. There are multiple second electrode modules 20, and the second electrode pieces 21 of the multiple second electrode modules 20 are arranged in a staggered manner. The multiple first electrode modules 10 and the multiple second electrode modules 20 are interleaved and interlocked, so that all the first electrode pieces 11 and all the second electrode pieces 21 are arranged in a staggered manner.

[0052] For the first electrode module 10 and the second electrode module 20 formed by bending, after bending, the spacing between two adjacent electrode pieces (first electrode piece 11 / second electrode piece 21) of the same module is relatively large, which will result in a lower electric field strength of the dust collection electric field, or require the power supply module to apply a larger output voltage. However, by arranging multiple modules in a cross configuration, the spacing between two adjacent electrode pieces of the same electrode module can be reduced, thereby reducing the spacing between adjacent first electrode pieces 11 and second electrode pieces 21. This is beneficial to improving the electric field strength of the dust collection electric field and reducing the output voltage of the power supply module.

[0053] The first bent portions 12 of different first electrode modules 10 can be staggered, and then each first electrode module 10 is connected to the high-voltage terminal of the power supply module. Alternatively, the first bent portions 12 of different first electrode modules 10 can be stacked and contacted in the width direction of the first electrode sheet 11 (and can be fixedly connected), so that as long as one first electrode module 10 is connected to the high-voltage terminal of the power supply module, multiple first electrode modules 10 can be connected to the same power supply module.

[0054] The second bends 22 of different second electrode modules 20 can be staggered, and each second electrode module 20 is then connected to the high-voltage terminal of the power supply module. Alternatively, the second bends 22 of different second electrode modules 20 can be stacked and contacted (fixed connection) in the width direction of the second electrode sheet 21. In this case, as long as one second electrode module 20 is connected to the high-voltage terminal of the power supply module, multiple second electrode modules 20 can be connected to the same power supply module.

[0055] The number of first electrode modules 10 and the number of second electrode modules 20 may be equal or unequal. The dimensions (e.g., length, inter-electrode spacing, electrode width, number of electrodes, etc.) of different first electrode modules 10 may be equal or unequal. Similarly, the dimensions (e.g., length, inter-electrode spacing, electrode width, number of electrodes, etc.) of different second electrode modules 20 may be equal or unequal.

[0056] In some exemplary embodiments, the frame 30 is provided with a potting groove 31, such as Figure 4 As shown, the first bent portion 12 and the second bent portion 22 are located within the potting groove 31. Subsequently, after the first bent portion 12 and the second bent portion 22 are connected to the power supply module, glue can be injected into the potting groove 31 to effectively isolate the first bent portion 12 and the second bent portion 22, and ensure that the first electrode module 10 and the second electrode module 20 are fixedly connected to the frame 30.

[0057] In some exemplary embodiments, the distance between adjacent first electrode plates 11 and second electrode plates 21 may be, but is not limited to, greater than or equal to 0.5 mm, to ensure that the dust collection electric field has sufficient electric field strength and is not prone to breakdown.

[0058] In some exemplary embodiments, the outer surface of the first electrode sheet 11 is covered with an insulating layer (not shown in the figure). The outer surface of the insulating layer is covered with a purification coating (not shown in the figure), which is configured to purify gaseous contaminants.

[0059] Covering the first electrode plate 11 with an insulating layer helps prevent the high-voltage module from conducting electricity through contact with external substances (such as the human body), thus avoiding safety accidents. Furthermore, the insulating layer covering the first electrode plate 11 prevents it from contacting air and causing air ionization, thereby preventing ozone generation, arcing, and unpleasant electrical noise. The second electrode plate 21 of the low-voltage module can be exposed without an insulating layer, which reduces the weakening effect of the insulating layer on the electric field strength, helping to maintain the high-voltage electric field strength between the first and second electrode plates 11. The purification coating can purify gaseous pollutants in the air. The dust-collecting electric field can use electrostatic dust collection technology to adsorb solid pollutants such as dust, allergens, and bacteria from the air onto the second electrode plate 21, achieving a dust collection function.

[0060] Therefore, the dust collection device provided in this application embodiment can not only achieve electrostatic dust collection, but also purify gaseous pollutants in the air, effectively improving the purification performance of the dust collection device.

[0061] In some exemplary embodiments, the first electrode module 10 carries the same charge as the solid contaminant, such as dust, and the second electrode module 20 carries the opposite charge. The first electrode module 10 provides a repulsive electrode, and the second electrode module 20 provides a collecting electrode. The solid contaminant, such as dust, is collected onto the second electrode plate 21 of the second electrode module 20, while the first electrode plate 11 of the first electrode module 10 remains exposed. This allows the purification coating to remain in contact with the air during long-term dust collection, thereby enabling long-term removal of gaseous contaminants such as toluene and formaldehyde from the air.

[0062] In some exemplary embodiments, the second electrode sheet 21 may also be covered with an insulating layer.

[0063] In some embodiments, the first electrode module 10 and the second electrode module 20 are metal conductors, such as copper plates, galvanized plates, stainless steel plates, aluminum plates, etc. The first electrode module 10 and the second electrode module 20 are configured as an integral structure formed by punching and bending the sheet conductors, and the first electrode sheet 11 and the second electrode sheet 21 are configured to be formed by bending after the sheet conductors are punched.

[0064] In other words, during the production process, the flat sheet conductor can be punched first, such as... Figure 3 As shown, the first bent portion 12 (or the second bent portion 22) and the first electrode sheet 11 (or the second electrode sheet 21) are punched out before bending. At this time, the first bent portion 12 (or the second bent portion 22) and the first electrode sheet 11 (or the second electrode sheet 21) are located on the same plane. Then, the punched sheet conductor is continuously bent to obtain the first electrode module 10 and the second electrode module 20.

[0065] The punching operation of the sheet conductor can be performed by a punch press, and the bending operation can be performed by a machine tool. Therefore, the integrated first electrode module 10 / second electrode module 20 can achieve industrial automation, which helps to reduce production costs.

[0066] In some exemplary embodiments, the insulating layer is an insulating film. The insulating film is configured to be obtained by performing a coating operation after the sheet conductor is punched and before bending, and then cutting off any excess insulating film (or cutting off the insulating film covering the cutout portion between adjacent first electrode sheets 11 before bending). The excess insulating film includes at least the insulating film located in the cutout portion between adjacent first electrode sheets 11, and may also include a portion extending beyond the outer contour of the electrode body.

[0067] In other words, during the production process, the flat sheet conductor can be punched first, such as... Figure 3 As shown, the first bent portion 12 (or the second bent portion 22) and the first electrode sheet 11 (or the second electrode sheet 21) before bending are punched out. Then, a film coating operation is performed to completely cover the outer surface of the punched sheet conductor with an insulating film, which also covers the cut-out portions. Therefore, the excess insulating film needs to be cut off, leaving only the insulating film on the outer surface of the punched sheet conductor, while the cut-out portions and portions exceeding the outer contour are cut off, or the insulating film covering the cut-out portions between adjacent first electrode sheets 11 before bending is cut off. After bending, the first electrode module 10 is obtained.

[0068] The coating process can be performed using a coating machine, while the film cutting process can be performed using a stamping machine. This allows for industrial automation of the electrode body and the coating process, which helps reduce production costs. The insulating film can have an adhesive backing and is glued onto the first electrode module 10.

[0069] As for the second electrode module 20, since it does not have an insulating layer, it can be directly cut and bent.

[0070] The only difference between the first electrode module 10 and the second electrode module 20 can be that the first electrode module 10 has an additional insulating film and a purification coating; the other shapes, sizes, and structures can be the same. This improves the versatility of the sheet conductor.

[0071] Of course, the number of first electrode modules 10 can also be one, and the number of second electrode modules 20 can also be one.

[0072] In some exemplary embodiments, the insulating layer comprises at least one of the following: PP (Polypropylene), PET (Polyethylene Terephthalate), PC (Polycarbonate), and ABS (Acrylonitrile Butadiene Styrene).

[0073] Therefore, the raw materials used in the production of insulating films can include monomers or composites of plastic films such as PP, PET, PC, and ABS. Of course, the composition of the insulating layer is not limited to the above-mentioned components.

[0074] In some exemplary embodiments, the purification coating includes a catalyst and / or an adsorbent. The catalyst can decompose gaseous pollutants through a catalytic reaction, thus achieving a purification effect. The adsorbent can adsorb gaseous pollutants through a physical reaction, thereby achieving a purification effect.

[0075] In some embodiments, the components of the purification coating include at least one of the following: manganese oxide catalyst, activated carbon powder, nanogel, boron, carbon, and nitrogen catalyst, and binder.

[0076] Manganese oxide catalysts are effective at purifying formaldehyde. Boron, carbon, and nitrogen catalysts are effective at purifying toluene. Activated carbon powder and nanogels are adsorbents with relatively high adsorption performance, capable of adsorbing gaseous pollutants (such as TVOC and odors) to achieve purification. Therefore, the dust collection device can not only efficiently filter solid pollutants such as dust, bacteria, and allergens, but also purify gaseous pollutants such as formaldehyde, toluene, and odors from the air.

[0077] In some embodiments, the composition of the purification coating, by weight, includes: 100 parts manganese oxide catalyst, 0-200 parts activated carbon powder, 0-20 parts nanogel, 0-200 parts boron, carbon, and nitrogen catalyst, and 30-60 parts binder. In other words, by weight, the ratio of manganese oxide catalyst: activated carbon powder: nanogel: boron, carbon, and nitrogen catalyst: binder is 100:(0-200):(0-20):(0-200):(30-60).

[0078] Furthermore, by weight, the ratio of manganese oxide catalyst: activated carbon powder: nanogel: boron carbon nitrogen catalyst: binder = 100: (10-200): (1-20): (10-200): (35-60).

[0079] Because the demand for formaldehyde removal is generally high, the amount of manganese oxide catalyst is relatively large, and other ingredients can be added as needed.

[0080] For example: the parts of activated carbon powder can be, but are not limited to, 0 parts, 10 parts, 30 parts, 50 parts, 80 parts, 100 parts, 120 parts, 150 parts, 180 parts, 200 parts, etc. The parts of nanogel can be, but are not limited to, 0 parts, 1 part, 3 parts, 5 parts, 8 parts, 10 parts, 12 parts, 15 parts, 18 parts, 20 parts, etc. The parts of boron, carbon, and nitrogen catalyst can be, but are not limited to, 0 parts, 10 parts, 30 parts, 50 parts, 80 parts, 100 parts, 120 parts, 150 parts, 180 parts, 200 parts, etc. The parts of binder can be, but are not limited to, 30 parts, 40 parts, 50 parts, 60 parts, etc.

[0081] Of course, the composition of the purification coating is not limited to the above range, and the proportion of each component is not limited to the above range either, and can be adjusted as needed.

[0082] In some exemplary embodiments, the frame 30 is an insulating frame. The first electrode module 10 and the second electrode module 20 can be mounted on the frame by means of fixing clips or potting. The insulating frame 30 may be provided with high-voltage lines, which are connected to the first electrode module 10 and the second electrode module 20 respectively. The high-voltage lines may also be connected to high-voltage resistors, conductive springs, and other structures to facilitate the reasonable setting of the position, input voltage, and output voltage of the power supply modules.

[0083] This application also provides an air handling device, including: a power supply module and a dust collection device as described in any of the above embodiments, wherein the power supply module is electrically connected to the first electrode module 10 and the second electrode module 20 and is configured to supply power to the dust collection device.

[0084] 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.

[0085] The high voltage output from the power supply module to the first electrode module 10 can be a negative high voltage. The power supply module is configured to output DC high voltage (such as DC constant voltage high voltage) to the dust collection device, thereby generating an electrostatic field between the first electrode plate 11 and the second electrode plate 21. This electrostatic field helps improve dust removal efficiency. Of course, the power supply module can also output pulsed high voltage to the dust collection device.

[0086] 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.

[0087] The charging module can be used to give solid pollutants the same charge as the first electrode module 10, so that solid pollutants can be adsorbed onto the second electrode plate 21, i.e. the collecting electrode, so that the purification coating on the first electrode plate 11, which is the repulsive electrode, remains exposed.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] This application also provides a control method for an air handling device as described in the above embodiments. Figure 5 As shown, the control methods include:

[0093] Step S202: Determine the target working mode. The types of target working modes include at least ordinary dust removal mode, ordinary purification mode, and enhanced dust removal and purification mode.

[0094] Step S204: Control the power supply module according to the determined target working mode.

[0095] The control method provided in this application embodiment, after determining the target working mode, can control the power supply module according to the determined target working mode to provide the corresponding high voltage to the power supply module, so that the air handling equipment can operate in ordinary dust removal mode, ordinary purification mode or enhanced dust removal and purification mode, realizing an air purification solution that integrates ordinary dust removal, ordinary purification, dust removal + purification and other functions.

[0096] In some exemplary embodiments, controlling the power supply module according to a determined target operating mode includes:

[0097] Based on the target working mode being the normal dust removal mode, the power supply module is controlled to supply power to the dust collection device and execute the preset low-voltage control strategy.

[0098] Based on the target working mode being the enhanced dust removal and purification mode, the power supply module is controlled to supply power to the dust collection device and execute the preset medium-voltage control strategy.

[0099] Based on the target operating mode being normal purification mode, the power supply module is shut down.

[0100] In some embodiments, the target operating mode further includes a self-cleaning activation mode. The power supply module is controlled according to the determined target operating mode, and the system further includes:

[0101] Based on the target working mode being the self-cleaning activation mode, the power supply module is controlled to supply power to the dust collection device and execute the preset high-voltage control strategy.

[0102] Among them, based on the low-voltage control strategy implemented by the power supply module, 3kV≤absolute value of the output voltage of the power supply module<6kV.

[0103] Based on the medium-voltage control strategy implemented by the power supply module, the absolute value of the output voltage of the power supply module is less than 15kV and 6kV ≤.

[0104] Based on the high-voltage control strategy implemented by the power supply module, the absolute value of the output voltage of the power supply module is ≤25kV and ≤15kV.

[0105] When the power supply module is off, the dust collection device is not powered. The purification coating can purify the air flowing through it with common gaseous pollutants such as formaldehyde and toluene, but it cannot perform dust removal; therefore, this can be called the ordinary purification mode. When the output voltage of the power supply module reaches -3kV to -6kV, the purification efficiency decreases because the active sites of the catalyst in the purification coating are occupied, and it mainly performs dust removal; therefore, this can be called the ordinary dust removal mode. When the output voltage of the power supply module reaches -6kV to -15kV, the dust collection electric field strength increases, and the dust removal efficiency increases. Furthermore, due to the activation of the active sites of the catalyst in the purification coating, electro-catalytic synergistic purification can be achieved, resulting in even higher purification efficiency; therefore, this can be called the enhanced dust removal purification mode. When the output voltage of the power supply module reaches -15kV to 25kV, the active sites of the catalyst in the purification coating are activated, enabling rapid consumption and decomposition of pollutants adsorbed on the surface of the purification coating, achieving the function of catalyst self-cleaning and activation (therefore, this can be called the self-cleaning and activation mode), which is beneficial for the long-term efficient use of the purification coating. In normal dust removal mode, normal purification mode, or enhanced dust removal and purification mode, the fan can be turned on, and air flows within the duct. In self-cleaning activation mode, the fan can be turned off, and airflow within the duct is essentially stopped.

[0106] During operation, some gaseous pollutants are directly decomposed by the purification coating, while others adhere to its surface. Therefore, after a period of cumulative operation, the amount of gaseous pollutants adhering to the surface increases, affecting the effective contact between the coating and airborne pollutants, reducing the electric field strength, and consequently decreasing purification efficiency. Thus, it is necessary to utilize a catalyst self-cleaning activation mode to consume and decompose the pollutants on the coating surface, restoring the dust collection device to its efficient purification function.

[0107] Furthermore, the activation voltage of the active sites of different catalysts may be different. Therefore, by adjusting the output voltage of the power supply module, a better purification effect can be achieved for a specific pollutant at a certain voltage.

[0108] It is understandable that the scope of low-voltage, medium-voltage, and high-voltage control strategies is not limited to the above ranges and can be adjusted as needed. For example, a critical value of 6kV can also be placed within the scope of a low-voltage control strategy, and 15kV can also be placed within the scope of a medium-voltage control strategy.

[0109] In some exemplary embodiments, the method for determining the target operating mode can be by receiving external instructions, such as a user selecting the operating mode via a remote control, control panel, or APP; or the machine can automatically determine it based on air quality detection results, such as rationally selecting a normal dust removal mode, a normal purification mode, or an enhanced dust removal and purification mode based on the concentration of solid pollutants and gaseous pollutants in the air. The catalyst self-cleaning activation mode can automatically operate after each run of the normal purification mode and the enhanced dust removal and purification mode, enabling the dust collection device to operate efficiently for a long period; alternatively, it can operate independently after the dust collection device has accumulated a certain period of operation to achieve energy saving.

[0110] The conditions for ending the operation of each target working mode can be determined based on the air quality detection results, such as ending when the air quality meets the set standard; or based on the running time, such as ending when the set running time is reached.

[0111] The following are some examples, comparative examples and experimental results (the air handling unit is a wall-mounted unit of a certain model currently on sale, with 100% air supply, and CCM refers to the cumulative purification volume).

[0112]

[0113] Comparative Example 1, Example 1, Example 2, and Example 3 all yielded experimental results under conditions where the cumulative purification capacity of the air handling equipment did not decrease (i.e., the dust collection device was in brand new condition). CCM refers to Cumulative Purification Capacity. In Example 4, the cumulative purification capacity (CCM) of the air handling equipment decreased to a set value (e.g., 50%), but no self-cleaning activation was performed. Based on this, the output voltage of the power supply module was -9kV, resulting in the above experimental results. In Example 5, the cumulative purification capacity (CCM) of the air handling equipment decreased to a set value (e.g., 50%), but self-cleaning activation was performed (catalyst self-cleaning activation via a -15kV voltage). Based on this, the output voltage of the power supply module was -9kV, resulting in the above experimental results. CADR refers to Clean Air Delivery Rate; a higher value indicates a better purification effect.

[0114] As can be seen from Comparative Example 1, without a purification coating, the dust collection device only has the function of removing solid pollutants (hereinafter referred to as dust removal function), and does not have the function of removing gaseous pollutants such as formaldehyde and toluene.

[0115] As can be seen from Example 1, after the purification coating is applied, the dust collection device does not need to be powered on, but it still has the purification function of removing gaseous pollutants such as formaldehyde and toluene (it has the purification function of ordinary purification mode).

[0116] As can be seen from the comparison between Example 2 and Example 1, when the power supply module executes the low-voltage control strategy, the dust collection device has both dust removal function and the function of removing gaseous pollutants such as formaldehyde and toluene. However, the purification effect on gaseous pollutants is reduced. This is because the low voltage causes the active sites of the catalyst to be occupied, resulting in a decrease in purification efficiency. Therefore, it is mainly used for dust removal and has the purification function of ordinary dust removal mode.

[0117] As can be seen from the comparison between Example 3 and Example 2, when the power supply module executes the medium-voltage control strategy, the dust collection device has both dust removal function and the function of removing gaseous pollutants such as formaldehyde and toluene. Moreover, the dust removal efficiency is increased, and the purification effect on gaseous pollutants is also improved. This is because the active sites of the catalyst are activated, and the electro-catalytic synergistic purification leads to increased purification efficiency and has the purification function of enhanced dust removal and purification mode.

[0118] As can be seen from the comparison between Example 4 and Example 3, after the cumulative purification capacity of the air handling equipment decreases to the set value, if the catalyst self-cleaning activation is not performed, the dust removal efficiency and the efficiency of removing gaseous pollutants will both decrease.

[0119] As can be seen from the comparison between Example 5 and Example 4, after the cumulative purification capacity of the air handling equipment decreases to the set value, the dust removal efficiency and the efficiency of removing gaseous pollutants can be restored through the self-cleaning activation of the catalyst.
