Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of air purification, and particularly relates to a stacked electrostatic dust removal system for air purification and a use method. BACKGROUND

[0002] The electrostatic technology brings the particulate matters in the air to charge by a direct current high-voltage power supply in an ionization zone, and the charged particulate matters are adsorbed by an electric field formed in a dust collection zone, so that the purification is completed. Various high-voltage electrostatic dust removal devices designed by using the principle of the electrostatic technology can complete the purification of a wide flow rate and full particulate pollution, can be relatively stably used in different environments such as different temperatures and humidities, and can be better applied to household, commercial, industrial, special and other fields, and has the characteristics of long service life, high purification efficiency, low operation cost, low maintenance cost and the like.

[0003] High-voltage electrostatic dust removal devices are used in occasions requiring large air flow purification, such as tunnel purification, industrial dust removal, oil smoke purification, etc. In order to increase the ventilation area, reduce the air flow rate, control the noise, and ensure the purification efficiency, multiple electrostatic dust removal modules need to be stacked. For example, CN202121230841 is a staggered electrostatic filtration system structure for tunnel air purification. When multiple electrostatic dust removal modules are stacked, how to achieve reliable high-voltage electrical connection between the electrostatic dust removal modules is a problem that needs to be solved by those skilled in the art. At present, multiple electrostatic dust removal modules used in occasions requiring large air flow purification are stacked in a side push-pull manner, and high-voltage electrical connection between the electrostatic dust removal modules is usually achieved by using a striker type and a spiral spring type. The so-called striker type refers to the use of a metal columnar body to compress an internal elastic element and tightly and elastically connect with the high-voltage electrical connection contact on the side of the adjacent electrostatic dust removal module. The so-called spiral spring type refers to the use of a spring with a large diameter at one end and a small diameter at the other end. The end with a small diameter is tightly connected with the high-voltage end on the side of the electrostatic dust removal module, and then gradually increases in diameter perpendicular to the side of the electrostatic dust removal module. The end with a large diameter is elastically connected with the adjacent electrostatic dust removal module. The high-voltage electrical connection contact of the adjacent electrostatic dust removal module is in contact with the spring end with a large diameter, and a columnar metal part is provided between them. The columnar metal part penetrates into the spring by a certain distance to form an interference contact, thereby achieving the stacking connection of multiple electrostatic dust removal modules. The high-voltage electrical connection structure of the above two types of electrostatic dust removal modules can only be used in side electrostatic dust removal module series touch, and is limited in many afterloading or space-limited occasions. Due to the use of side electrical connection, the electrostatic dust removal module is mainly composed of sheet metal parts, which is heavy. Generally, the electrostatic dust removal module used in large air flow occasions weighs 300 kg, and the lightest one weighs 100-200 kg. There are even heavier ones. It is difficult to move such a heavy electrostatic dust removal module. During installation, it is difficult to push and pull multiple electrostatic dust removal modules along the side, especially the electrostatic dust removal modules close to the inside. During maintenance, if the internal electrostatic dust removal module needs to be replaced, the electrostatic dust removal modules on the outside need to be removed one by one, which causes great inconvenience to installation and maintenance.

DETAILED DESCRIPTION

[0045] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0046] Example 1:

[0047] like Figure 1 As shown, a stacked electrostatic dust removal system for air purification includes a frame 1 and a plurality of electrostatic dust removal modules 2 located within the frame 1. The plurality of electrostatic dust removal modules 2 are arranged sequentially, and adjacent electrostatic dust removal modules 2 are detachably connected by electrical connection components 3. Meanwhile, to improve the safety of the electrical connection components 3, an insulating layer is provided around the electrical connection components 3.

[0048] Specifically, the frame 1 is a frame structure, and includes multiple layers of crossbeams 4 and columns. The ends of the crossbeams 4 are connected to the columns to improve stability. The crossbeams 4 have mounting positions for accommodating the electrostatic dust removal module 2, and the electrostatic dust removal module 2 can be directly placed in the mounting positions from the front or back of the frame 1.

[0049] Specifically, the electrical connection component 3 is made of a conductive material, preferably iron or steel. The two ends of the electrical connection component 3 are respectively connected to the high-voltage terminals of adjacent electrostatic precipitator modules 2. It is worth noting that the electrostatic precipitator module 2 includes an ionization zone and a dust removal zone, and both the high-voltage terminals of the ionization zone and the dust removal zone need to be connected at high voltage via the electrical connection component 3. Both the high-voltage terminals of the ionization zone and the dust removal zone are electrically connected to a high-voltage power supply.

[0050] A method of using a stacked electrostatic precipitator system for air purification includes:

[0051] During installation, several electrostatic dust removal modules 2 are placed sequentially in the installation position from the front or back of the frame 1, so that several electrostatic dust removal modules 2 are stacked. The high voltage ends of adjacent electrostatic dust removal modules 2 are electrically connected through electrical connection components 3, and one electrostatic dust removal module 2 is electrically connected to an external high voltage power supply.

[0052] For multiple electrostatic precipitators 2 in the same layer, the electrostatic precipitator at the outermost side is firstly connected to the output of the high-voltage power supply directly or indirectly, and the adjacent electrostatic precipitators are connected in sequence through the electric connection assembly 3 in the horizontal state. It is worth mentioning that two adjacent electrostatic precipitators use two electric connection assemblies 3 (one for connecting the ionization zone and one for connecting the dust collection zone).

[0053] For multiple electrostatic precipitators 2 in multiple layers, the electrostatic precipitator at the outermost side of a layer is firstly connected to the output of the high-voltage power supply directly or indirectly, and the adjacent electrostatic precipitators in the layer are connected in sequence through the electric connection assembly 3 in the horizontal state. An electrostatic precipitator in another layer is connected to the electrostatic precipitator connected to the high-voltage power supply directly or indirectly through the electric connection assembly 3 in the vertical state, and then connected to the electrostatic precipitators in the same layer as the electrostatic precipitator through the electric connection assembly 3 in the horizontal state.

[0054] In case of failure, when one or more electrostatic precipitators 2 fail, the electric connection assembly 3 connected to the failed electrostatic precipitator 2 is disassembled, the failed electrostatic precipitator 2 is removed from the installation position, a new or repaired electrostatic precipitator 2 is placed in the installation position, and the disassembled electric connection assembly 3 is reassembled.

[0055] Embodiment Two:

[0056] As shown in Figure 2 , Figure 3 , the same parts of this embodiment as embodiment one are not described again, and the difference is:

[0057] Specifically, the electric connection assembly 3 includes two clamping parts 5 and a connecting part 6 between the two clamping parts 5, and the clamping part 5 is electrically connected to the high-voltage end 8.

[0058] In order to save materials as much as possible, when the electric connection assembly 3 is in the horizontal state, the distance between the two nearest high-voltage ends of two adjacent electrostatic precipitators is A, and the length of the connecting part 6 is L, then L = A + n x B, where B represents the distance between the two adjacent high-voltage ends in the electrostatic precipitator, and n is an integer. When the electric connection assembly 3 is in the vertical state, the minimum distance between two adjacent electrostatic precipitators is D, which includes the lower frame height of the upper electrostatic precipitator, the upper frame height of the lower electrostatic precipitator, and 1 times the distance between the two adjacent high-voltage ends in the electrostatic precipitator, and the length of the connecting part 6 is L, then L ≥ D.

[0059] It is worth noting that the minimum distance between the connecting part 6 and the electrostatic precipitator module 2 is half the distance between two adjacent high-voltage terminals in the electrostatic precipitator module. If an insulating layer is provided around the connecting part 6, the minimum distance between it and the electrostatic precipitator module 2 can be further shortened. In other words, the insulating layer can reduce the front and back space of the stacked electrostatic precipitator system for air purification.

[0060] In this embodiment, both the clamping part 5 and the high-pressure end 8 have a first through hole, and a first locking member 7 for fastening the clamping part 5 and the high-pressure end 8 is provided in the first through hole. Preferably, the first locking member 7 is a bolt, screw, cotter pin, or elastic cotter pin.

[0061] Preferably, the connecting part 6 can take various forms, such as a straight line, an arc, or a curve.

[0062] Example 3:

[0063] like Figure 4 As shown, the parts that are the same as those in Embodiments 1 and 2 will not be repeated here. The differences are as follows:

[0064] The clamping part 5 consists of two parallel legs 9. One end of the leg 9 is a free end, and the other end of the leg 9 is connected to the connecting part 6. The high-voltage end is inserted between the two legs 9.

[0065] Preferably, the width of the support leg 9 is equal to the width of the connecting part 6, or the width of the support leg 9 is less than the width of the connecting part 6, which saves material and ensures the firmness and reliability of the electrical connection between the clamping part 5 and the high-voltage end. At the same time, the cross-section of the support leg 9 can be square, rectangular, semi-circular or circular, and the shape is not specifically limited.

[0066] Considering the difficulty of molding and processing, the entire electrical connection assembly is welded together from two sub-modules. The number of solder joints is increased at the connection between the support leg 9 and the connecting part 6 to improve stability.

[0067] In some other embodiments, such as Figure 5 As shown in (d), the free end of the support leg 9 has a bevel 10, and the bevels 10 of the two support legs 9 are in opposite directions to form a plug-in interface 11. The high voltage end is inserted between the two support legs 9 through the plug-in interface 11.

[0068] In some other embodiments, such as Figure 5 As shown in (a), the free end of the support leg 9 is bent away from the other support leg to form a wing leg 12. The wing legs 12 on the two support legs 9 form a connector 11, through which the high-voltage terminal is inserted between the two support legs 9. The connector 11 forms an angle, facilitating quick insertion for installation and maintenance.

[0069] Specifically, in order to improve the clamping stability, the two legs 9 are in contact, as shown in Figure 5 (a) and (d). Alternatively, the parts adjacent to the insertion port 11 are in contact, as shown in Figure 5 (b) and (c), that is, the leg 9 has a curvature, so that a gap is formed between the two legs 9, wherein the maximum opening distance of the curvature (i.e. the width of the gap) matches the thickness of the high-voltage end, and is generally set to be equal, such as 0.8-1.5mm, Figure 5 The width of the gap in (b) is 0.8-1.5mm, or greater than the corresponding thickness value, and the maximum opening distance of the curvature is the maximum distance between the two legs 9 in the natural state. Figure 5 (c) is similar to Figure 5 (b), mainly symmetrical arrangement, more uniform stress. The curvature can be appropriately increased according to the actual clamping needs, and the clamping force is increased as much as possible.

[0070] In other embodiments, the leg 9 can have multiple curvatures, which can preset the clamping force or can buffer the prestress, and better clamp the high-voltage end.

[0071] Embodiment four:

[0072] The same parts of this embodiment as embodiments one to three will not be repeated, and the difference is:

[0073] As shown in Figure 6 , Figure 7 The leg 9 and the high-voltage end 8 both have a second through hole, and the two legs 9 form an insertion port through the wing, and the second through hole is provided with a second locking member 13 for fastening the clamping part 5 and the high-voltage end 8, and the high-voltage end 8 is inserted between the two legs 9 through the insertion port and locked by the second locking member 13.

[0074] Preferably, the second locking member 13 is a bolt, screw, split pin or elastic split pin. In addition, the two legs 9 can also not form an insertion port, or the two legs 9 form an insertion port through the bevel, and at the same time, the leg 9 can be provided with a curvature according to needs.

[0075] Embodiment five:

[0076] The same parts of this embodiment as embodiments one to four will not be repeated, and the difference is:

[0077] As shown in Figure 8 , Figure 9As shown, the two legs 9 have protrusions 14 in opposite directions, and the protrusions 14 are connected to the wing 12, and the two legs 9 form a plug-in interface through the wing. At the same time, the two legs 9 are abutted at the positions adjacent to the plug-in interface, and the high-voltage end 8 has a third through hole for accommodating the abutted positions of the two legs 9, and the high-voltage end 8 is inserted between the two legs 9 through the plug-in interface and the protrusions 14.

[0078] It is worth noting that the protrusions 14 are arcs with a certain height, and multiple protrusions 14 can be arranged on the legs 9.

[0079] That is, the high-voltage end 8 is pre-formed with a third through hole, and when the high-voltage end 8 is pushed between the two legs 9, the abutted positions of the two legs 9 fall into the third through hole and are clamped. At the same time, the curvature of the protrusions 14 increases the clamping force and the elastic deformation amount.

[0080] Preferably, the third through hole is a square hole, and the side length of the square hole is 1.5-5mm, preferably 2mm, larger than the linear length of the abutted positions of the two legs 9, so as to ensure that the abutted positions of the two legs 9 can completely fall into the third through hole. The third through hole can also be a rectangular hole, and the distance (i.e. length) between the upper and lower sides of the rectangular hole is 1.5-5mm, preferably 2mm, larger than the linear length of the abutted positions of the two legs 9. Similarly, the third through hole can be a circular hole, a waist circular hole, etc. Regardless of the form of the third through hole, it can accommodate the linear length of the abutted positions of the two legs 9, so that the abutted positions of the two legs 9 can be clamped in the third through hole, and the preset elastic force can be better released. The staff can judge whether the two legs 9 are clamped in the correct position by the change of force when clamping into the third through hole, which is beneficial to rapid installation and maintenance.

[0081] In some other embodiments, as shown in Figure 10 , Figure 11 the abutted positions of the two legs 9 are misaligned. Correspondingly, the high-voltage end 8 is pre-formed with a fourth through hole, and when the high-voltage end 8 is pushed between the two legs 9, the misaligned abutted positions of the two legs 9 fall into the fourth through hole and are clamped. Since the abutted positions of the two legs 9 are misaligned, a larger clamping force can be preset in advance, which can provide a larger buffer prestress and increase the electrical contact area; and Figure 9 Compared with the form shown in the above embodiment, under the same conditions, the misaligned structure increases the distance between the outer side of the electrical connection assembly and the grounding end of the electrostatic dust removal module. Under the same conditions, a higher ionization and dust collection voltage can be set, and the higher the ionization and dust collection voltage, the higher the efficiency of the electrostatic dust removal module, thereby improving the space utilization rate of the purified area. Under the same space, a higher purification efficiency can be achieved. In addition, the misaligned structure design further improves the firmness of the electrical connection and the clamping force of the electrical connection assembly.

[0082] Similarly, the fourth through hole is set in a similar manner to the third through hole, and will not be described again here. It is worth noting that the linear length of the misaligned fit is 2-6mm, preferably 3mm.

[0083] Example 6:

[0084] like Figure 12 As shown, the parts that are the same as those in Embodiment 1 will not be repeated here. The differences are as follows:

[0085] The electrical connection assembly 3 includes two clamping portions 5 and a connecting portion 6 located between the two clamping portions 5. The clamping portions 5 are electrically connected to the high-voltage end. Preferably, the connecting portion 6 is a straight line, an arc, or a curve.

[0086] The clamping part 5 has a U-shaped included angle 15 protruding from its main body, and the high-voltage end is inserted between the U-shaped included angle 15 and the clamping part body. Preferably, according to the actual electrical connection requirements, the U-shaped included angle 15 can be located above, below or to the side of the clamping part body.

[0087] A U-shaped angle of 15° is formed by mechanically bending a metal part of a certain strength. This method is convenient, quick, and low-cost, and is suitable for mass production. The width of the U-shaped angle of 15° is 10-20mm, and its length is 20-40mm. Preferably, the width is 15mm and the length is 30mm.

[0088] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
