Description

Technical Field

[0001] This application relates to the field of dust collector technology, specifically to an electrostatic precipitator and its anode plate array. Background Technology

[0002] Electrostatic precipitators (including hybrid electrostatic precipitators and bag filters) all employ electric field dust removal at their front end. This method utilizes the high-voltage ionization of the discharge electrode to generate a large number of negative ions in the flue gas. These negative ions adsorb onto the dust particles in the flue gas, giving the dust particles a negative charge. Due to the principle of opposite charges attracting, the negatively charged dust particles move towards the grounded anode plate and are eventually captured by it. Once the dust on the anode plate reaches a certain thickness, the anode plate is vibrated, causing the dust to fall off into the bottom ash hopper, thus cleaning the anode plate. The vibrating mechanism is typically installed on the top or side of the anode plate.

[0003] The electrostatic precipitator's electrostatic precipitator zone includes several flue gas channels. Each flue gas channel is formed by two rows of anode plates, with a cathode discharge electrode positioned at the center of the channel, between the two anode plate rows. Each anode plate row comprises multiple anode plates arranged along the extension direction of the flue gas channel, with both the top and bottom ends of the anode plates connected to corresponding fixing components in the height direction. In related technologies, adjacent anode plates in a row are not connected. During cleaning operations, the rapping force of the vibrator is transmitted vertically, with stronger force closer to the vibrator and weaker force farther away, resulting in uneven force distribution and poor cleaning effect on the anode plates.

[0004] Therefore, how to improve the cleaning effect on the anode plate array is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this application is to provide an electrostatic precipitator and its anode plate array, the structural arrangement of which provides technical conditions for improving the dust removal effect.

[0006] To solve the above-mentioned technical problems, embodiments of this application provide an anode plate array for an electrostatic precipitator, the anode plate array comprising a plurality of anode plates arranged along a first direction;

[0007] The anode plate has a fixing portion on both sides in the first direction, and the fixing portion includes a fixing substrate; along the first direction, the two adjacent fixing substrates of two adjacent anode plates are arranged opposite to each other.

[0008] The anode plate row also includes a connector that passes through two adjacent fixed substrates to connect two adjacent anode plates.

[0009] In some possible implementations, the connector includes a first component and a second component; the first component includes a first part and a second part that are connected to each other, and the first part and the second part are at a set angle.

[0010] Two adjacent fixed substrates are defined as a first fixed substrate and a second fixed substrate. The first component is located on the side of the first fixed substrate facing away from the second fixed substrate. The second component passes through the first fixed substrate and the second fixed substrate. The second component is welded to the first fixed substrate. The second member is located on the side of the second fixed substrate facing away from the first fixed substrate. The second member is welded to the second component.

[0011] In some possible implementations, the connector includes a connector head and two connector legs, the first ends of the two connector legs are fixedly connected to the connector head, and the two connector legs are arranged opposite to each other;

[0012] Two adjacent fixed substrates are defined as the first fixed substrate and the second fixed substrate. The connection head is located on the side of the first fixed substrate facing away from the second fixed substrate, and the connection head can abut against the first fixed substrate.

[0013] The connecting leg passes through the first fixed substrate and the second fixed substrate. The connecting leg is bent through the second end of the second fixed substrate, and the bending directions of the two connecting legs are opposite.

[0014] In some possible implementations, the connector is an integral structural component, formed by bending a sheet metal with a thickness of 1mm to 2mm.

[0015] In some possible implementations, the fixed substrate has a through hole through which the connector passes, the through hole having a first height dimension in the height direction of the anode plate, and the connector having a second height dimension in the height direction of the anode plate, the first height dimension being greater than the second height dimension.

[0016] In some possible implementations, the fixed substrate has through holes through which the connector passes, and the fixed substrate has a plurality of through holes spaced apart along the height direction of the anode plate.

[0017] In some possible implementations, the thickness of the anode plate is 1mm to 2mm, and / or the spacing between two adjacent through holes is 1m to 3m.

[0018] In some possible implementations, the anode plate includes a plate body and two fixing parts, which are respectively located on both sides of the plate body. The fixing parts have a groove-shaped structure, and the bottom wall of the groove-shaped structure forms the fixing substrate. The groove openings of the two fixing parts of the anode plate are arranged facing each other.

[0019] In some possible implementations, there is a gap between two adjacent fixed substrates of two adjacent anode plates in the first direction, so that at least one fixed substrate can move relative to the connector in the first direction.

[0020] This application also provides an electrostatic precipitator, which includes a housing and an anode plate array installed inside the housing, wherein the anode plate array is any of the anode plate arrays described above.

[0021] The anode plate array provided in this application embodiment is used in an electrostatic precipitator. Multiple anode plates in the array are connected in their arrangement direction to form a single unit. When the anode plate array needs to be cleaned, the rapping force applied to the anode plates by the rapping device can be transmitted not only along the height direction of the anode plates but also along the arrangement direction of the multiple anode plates in the array. This improves the uniformity of the rapping force distribution on the anode plates, thereby enhancing the cleaning effect. Attached Figure Description

[0037] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] The ordinal numbers used in the embodiments of this application are for distinguishing different components with the same name and do not indicate a specific order or primary / secondary relationship. The term "multiple" in this application refers to two or more.

[0039] For ease of understanding and description, this paper constructs three directions: the first direction x, the second direction y, and the third direction z. The first direction x represents the arrangement direction of multiple anode plates in the anode plate array, the second direction y represents the arrangement direction of the multiple anode plate arrays, and the third direction z represents the height direction of either the anode plates or the arrays. Typically, the first direction x, the second direction y, and the third direction z are mutually perpendicular.

[0040] For the sake of brevity and ease of understanding, the following description will be combined with the electrostatic precipitator and its anode plate array, and the beneficial effects will not be discussed again.

[0041] Please refer to Figure 1 and Figure 2 , Figure 1This is a structural diagram of the electric field region of the electrostatic precipitator provided in one embodiment of this application. Figure 2 for Figure 1 Top view.

[0042] In this embodiment, the electrostatic precipitator is provided with an electrostatic precipitation zone, which can be located inside the shell of the electrostatic precipitator. The electrostatic precipitation zone includes an anode plate array 110 and a cathode discharge electrode 120.

[0043] The anode plate row 110 includes a plurality of anode plates 200 arranged in sequence, and the arrangement direction of the plurality of anode plates 200 in the anode plate row 110 is the first direction x.

[0044] The electrostatic precipitator zone is equipped with multiple rows of anode plates 110, which are arranged along a second direction y, forming a flue gas channel between two adjacent rows of anode plates 110. The flue gas channel extends in a first direction x. Multiple cathode discharge electrodes 120 are arranged along the first direction x within the flue gas channel. Typically, the cathode discharge electrodes 120 are located at the midpoint between two adjacent rows of anode plates 110.

[0045] During operation, as flue gas flows through the flue gas channel, the negatively charged cathode discharge electrode 120 ionizes the flue gas with high voltage, causing the dust particles in the flue gas to become negatively charged. Due to the principle of attraction between opposite charges, the negatively charged dust particles move towards the grounded anode plate array 110 and are captured by the anode plate array 110. When the anode plate array 110 needs to be cleaned, the anode plates 200 of the anode plate array 110 can be cleaned by a rapping device placed on the top or side of the anode plate array 110, causing the dust to fall into the ash hopper located at the bottom of the anode plate array 110.

[0046] Figure 1 and Figure 2 A partial schematic diagram of the electrostatic precipitator zone is provided. In practical applications, the number of anode plate rows 110, the number of cathode discharge electrodes 120 in a flue gas channel, and the relevant dimensions of the anode plate rows 110 can be set as needed, and no specific limitations are made here.

[0047] This application focuses on structural improvements to the anode plate array 110 to ensure a more uniform distribution of the rapping force during dust removal, thereby improving the dust removal effect. The following description focuses on the structure of the anode plate array 110; other structures of the electrostatic precipitator can be implemented with reference to existing technologies and will not be discussed further.

[0048] Please refer to this as well. Figures 3 to 7 , Figure 3 This is a front view of the anode plates in an anode plate array provided in one embodiment of this application. Figure 4 for Figure 3 The side view of the anode plate shown is shown. Figure 5 for Figure 3 The top view of the anode plate shown. Figure 6 for Figure 4 A magnified view of the area where the through hole is located. Figure 7 for Figure 2 A magnified view of the connection between two adjacent anode plates.

[0049] This embodiment provides an anode plate array 110, which includes a plurality of anode plates 200 arranged along a first direction x. Each anode plate 200 has a fixing portion 220 on both sides of the first direction x, and the fixing portion 220 includes a fixing substrate 221. Along the first direction x, two adjacent fixing substrates 221 of two adjacent anode plates 200 are arranged opposite to each other.

[0050] The anode plate row 110 also includes a connector 300, which passes through two adjacent fixed substrates 221 to connect two adjacent anode plates 200. It can be understood that the two fixed substrates 221 through which the connector 300 passes belong to two adjacent anode plates 200.

[0051] Using the above scheme, the multiple anode plates 200 of the anode plate row 110 are connected as a whole in their arrangement direction (i.e., the first direction x) by the connector 300. When the anode plate row 110 needs to be cleaned, the rapping force applied by the rapping device to the anode plate 200 can be transmitted not only along the height direction of the anode plate 200 (i.e., the third direction z), but also along the arrangement direction of the multiple anode plates 200 in the anode plate row 110 (i.e., the first direction x). In this way, the uniformity of the rapping force distribution on the anode plate 200 can be improved, thereby improving the cleaning effect of the anode plate 200.

[0052] For ease of explanation, the following definitions apply to two adjacent anode plates 200: the first anode plate 200A and the second anode plate 200B. The fixing portion 220 of the first anode plate 200A adjacent to the second anode plate 200B is the first fixing portion 220A, and the fixing substrate 221 of the first fixing portion 220A is the first fixing substrate 221A. Similarly, the fixing portion 220 of the second anode plate 200B adjacent to the first anode plate 200A is the second fixing portion 220B, and the fixing substrate 221 of the second fixing portion 220B is the second fixing substrate 221B. Figure 4 As shown, the anode plate 200 on the left is the first anode plate 200A, and the anode plate 200 on the right is the second anode plate 200B.

[0053] In some embodiments, the connector 300 includes a first component 310 and a second component 320. The first component 310 includes a first part 311 and a second part 312 that are connected to each other, and the first part 311 and the second part 312 are at a set angle.

[0054] The first part 311 of the first component 310 is located on the side of the first fixed substrate 221A facing away from the second fixed substrate 221B. The second part 312 passes through the first fixed substrate 221A and the second fixed substrate 221B. The second part 312 is welded to the first fixed substrate 221A. The second component 320 is located on the side of the second fixed substrate 221B facing away from the first fixed substrate 221A. The second component 320 is welded to the second part 312.

[0055] After the above configuration, the first part 311 of the first component 310 can interfere with the first fixed substrate 221A to prevent the second part 312 from detaching from the first fixed substrate 221A and the second fixed substrate 221B. After the second component 320 is welded to the second part 312, the second component 320 can interfere with the second fixed substrate 221B to prevent the second part 312 from detaching from the first fixed substrate 221A and the second fixed substrate 221B. This can ensure the stability of the connection between the first anode plate 200A and the second anode plate 200B, thereby improving the uniformity of the vibration force distribution.

[0056] In this process, the first part 311 of the first component 310 is welded to the first fixed substrate 221A, so that the first component 310 and the first anode plate 200A are fixed as a whole. After the second component 320 is welded to the second part 312, the second component 320 and the first component 310 are fixed as a whole. Thus, the connector 300 and the first anode plate 200A are fixed as a whole. There is no fixation between the second component 320 and the second fixed substrate 221B, and the two are allowed to have room for movement. That is, there is room for relative movement between the first anode plate 200A and the second anode plate 200B in the first direction x.

[0057] During assembly, the first fixed substrate 221A and the second fixed substrate 221B can have a gap s in the first direction x. Since the second member 320 is not fixed to the second fixed substrate 221B, the second fixed substrate 221B can have a certain amount of movement relative to the second member 312 in the first direction x. Figure 4 As shown, the second fixed substrate 221B can move to the left in the direction of the first fixed substrate 221A. In practical applications, when the anode plate 200 expands and deforms due to high temperature (e.g., around 100°C), due to the aforementioned connection relationship, the first anode plate 200A and the second anode plate 200B can move relative to each other in the first direction x to offset the deformation and expansion of the anode plate 200, preventing the anode plates 200 from jamming or tearing, and ensuring the reliability of the anode plate array 110.

[0058] The gap s between the first fixed substrate 221A and the second fixed substrate 221B in the first direction x can be set as needed. Generally, the expansion deformation of the anode plate 200 in the first direction x is relatively small, and the gap s can be set to 1mm~3mm, or it can be adjusted as needed.

[0059] In some implementations, the first fixed substrate 221A is approximately parallel to the second direction y, and the second fixed substrate 221B is also approximately parallel to the second direction y. This facilitates the connection of the connector 300 to connect two adjacent anode plates 200.

[0060] In some implementation schemes, the first component 310 can be a bent plate with an L-shaped cross-section, that is, the first part 311 and the second part 312 can be set at a 90° angle.

[0061] In some implementation schemes, the second component 320 can be a columnar member with a cross-section that is circular, rectangular, or elliptical.

[0062] In some embodiments, the fixed substrate 221 has a through hole 2211 through which the connector 300 passes. The through hole 2211 has a first height dimension H in the height direction (i.e., the third direction z) of the anode plate 200, and the connector 300 has a second height dimension in the height direction of the anode plate 200. The first height dimension H is set to be greater than the second height dimension. In this way, two adjacent anode plates 200 can move relative to each other in the height direction. When the anode plates 200 deform and expand due to the high-temperature working environment of the electrostatic precipitator, there is a relative amount of movement between the two adjacent anode plates 200 in the height direction, which can offset the deformation and expansion and prevent the anode plates 200 from jamming or tearing.

[0063] Connector 300 adopts Figure 7 In the embodiment shown, the connector 300 and the first anode plate 200A are fixedly connected as a whole. When the anode plate 200 deforms due to high temperature, the connector 300 and the first anode plate 200A can move together relative to the second anode plate 200B in the height direction.

[0064] In a specific implementation, the width of the through hole 2211 in the second direction y can be greater than that of the second part 312 of the first component 310. This allows the second anode plate 200B to move relative to the second part 312 in the first direction x. It can be understood that the second part 312 and the through hole 2211 have a clearance fit.

[0065] In one application example, the first height dimension H of the through hole 2211 can be 70 mm, and the width dimension of the through hole 2211 in the second direction y can be 5.5 mm. The first component 310 of the connector 300 can be formed by bending a plate with a thickness of approximately 5 mm. Thus, the second part 312 of the first component 310 has a thickness of 5 mm in the second direction y, which can smoothly pass through the through hole 2211 of the first fixed substrate 221A and the second fixed substrate 221B, and allows the second fixed substrate 221B to move relative to the second part 312 in the first direction x. The second component 320 of the connector 300 can be a columnar member with a diameter of 8 mm. After the second component 320 is welded to the end of the second part 312 away from the first part 311, the second component 320 and the first part 312 can restrict the relative position of the first anode plate 200A and the second anode plate 200B in the first direction x. The second height dimension of both the first component 310 and the second component 320 in the height direction can be 30mm. Thus, after connecting the first anode plate 200A and the second anode plate 200B, the two can have a relative range of motion of about 40mm in the height direction.

[0066] In practical applications, all of the above-mentioned dimensions can be adjusted as needed.

[0067] Figure 7 In the connection scheme shown, the first component 310 of the connector 300 is welded to the first anode plate 200A, and the second component 320 is welded to the first component 310. This can ensure the connection strength between two adjacent anode plates 300 and has high stability. It can be applied to scenarios where the anode plate 200 is high (e.g., greater than 12m) and the connection strength of the anode plate 200 is relatively high.

[0068] In addition to the structural form of connector 300 Figure 7 Besides the embodiments shown, other implementations are also possible. These can be referred to in conjunction with these embodiments. Figure 8 and Figure 9 understand, Figure 8 This is a partial enlarged view of the connection portion between two adjacent anode plates in another embodiment provided in this application. Figure 9 for Figure 8 The diagram shows the structure of the connector before connection.

[0069] Figure 8 and Figure 9 The embodiment shown differs from the previous embodiment in that the specific structure of the connector 300 is different. The other structural settings and connection relationships can be referred to the description of the previous embodiment and will not be repeated.

[0070] exist Figure 8 and Figure 9In the illustrated embodiment, the connector 300 includes a connector head 330 and two connector legs 340. The first ends of the two connector legs 340 are fixedly connected to the connector head 330, and the two connector legs 340 are arranged opposite to each other. The connector head 340 is located on the side of the first fixed substrate 221A facing away from the second fixed substrate 221B, and the connector head 340 can abut against the first fixed substrate 221A. The connector legs 340 pass through the first fixed substrate 221A and the second fixed substrate 221B, and the second ends of the connector legs 340 passing through the second fixed substrate 221B are bent, with the bending directions of the two connector legs 340 being opposite.

[0071] by Figure 8 As shown, the connecting head 340 is located on the left side of the first fixed substrate 200A. The left end of the connecting leg 340 is the first end connected to the connecting head 340. The right end of the connecting leg 340 passes through the first fixed substrate 200A and the second fixed substrate 200B in sequence and is then bent to form a bent portion that can abut against the second fixed substrate 200B. In this way, the relative position of the first anode plate 200A and the second anode plate 200B in the first direction x can be restricted by the connecting head 340 and the bent portion.

[0072] After connection, the two bent parts of the two connecting legs 340 of the connector 300 are roughly V-shaped.

[0073] Figure 9 for Figure 8 The structure before the middle connector 300 connects the two anode plates 300.

[0074] Figure 8 and Figure 9 The connector 300 shown can connect two anode plates 300 relatively quickly and is easy to install. It is suitable for applications where the height of the anode plates 200 is low (e.g., less than 12m) and the connection strength requirements of the anode plates 200 are not high, thus shortening the project time.

[0075] In one implementation, Figure 9 The connector 300 shown can be a one-piece structural component, formed by bending a sheet metal with a thickness of 1mm to 2mm. This ensures the structural strength of the connector 300 while facilitating its formation. It also allows the two connecting legs 340 to bend in opposite directions to form bent sections when connecting the two anode plates 200. The connecting legs 340 can be bent manually or with the aid of tools.

[0076] The connector head 330 of connector 300 can be bent to form a similar shape. Figure 8 and Figure 9The structure is either elliptical or racetrack-shaped. Before connection, the connector 300 is roughly T-shaped.

[0077] use Figure 8 and Figure 9 When the connector 300 is shown, the first fixed substrate 221A and the second fixed substrate 221B can also have a gap in the first direction x, so that they can have relative movement in the first direction x, avoiding defects such as jamming or tearing of the anode plate 200 due to high temperature deformation. The two connecting legs 340 are clearance-fitted with the through hole 2211, so that both the first fixed substrate 221A and the second fixed substrate 221B can move relative to the connecting legs 340 in the first direction x.

[0078] use Figure 8 and Figure 9 When the connector 300 is shown, the second height dimension of the connector 300 in the height direction is also smaller than the first height dimension H of the through hole 2211, so that the two adjacent anode plates 200 have relative mobility in the height direction, and avoid the anode plates 200 from jamming or tearing due to high temperature deformation.

[0079] In one application example, the first height dimension H of the through hole 2211 can be 70 mm, and the width dimension of the through hole 2211 in the second direction y can be 5.5 mm. The second height dimension of the connector 300 in the height direction can be 30 mm, so that the first anode plate 200A and the second anode plate 200B can have a relative range of motion of about 40 mm in the height direction after connection. The dimensions of the two connecting legs 340 in the second direction y can be 5 mm, so as to smoothly pass through the through hole 2211 of the first fixed substrate 221A and the second fixed substrate 221B, and so that the first fixed substrate 221A and the second fixed substrate 221B can move relative to the connecting legs 340 in the first direction x.

[0080] In practical applications, all of the above-mentioned dimensions can be adjusted as needed.

[0081] In the aforementioned embodiments, the height dimension of the fixing portion 220 of the anode plate 200 is consistent with that of the anode plate 200. Along the height direction of the anode plate 200, the fixing substrate 221 is provided with a plurality of through holes 2211 arranged at intervals. In this way, the stability and connection strength of the connection between two adjacent anode plates 200 can be guaranteed, which is conducive to better transmission of rapping force in the first direction x, and can help improve the dust removal effect.

[0082] The anode plate 200 should not be too thick, as this will result in poor vibration force transmission. The anode plate 200 should also not be too thin, as this will easily deform and break. The anode plate 200 can be made of a plate with a thickness of 1mm to 2mm to better balance structural strength and vibration force transmission.

[0083] For example, the spacing between two adjacent through holes 2211 on the fixing substrate 221 of the anode plate 200 in the height direction is 1m to 3m to ensure the connection strength between the anode plates 200.

[0084] In the foregoing embodiments, such as Figure 5 As shown, the anode plate 200 includes a plate body 210 and two fixing portions 220. The two fixing portions 220 are located on both sides of the plate body 210. The fixing portions 220 are groove-shaped structures 220', and the bottom wall of the groove-shaped structure 220' forms a fixing substrate 221. The groove openings of the two fixing portions 220 of the anode plate 200 are arranged facing each other. In this way, setting the fixing portions 220 as groove-shaped structures 220' can increase the dust collection area of ​​the anode plate 200 and improve the structural strength of the anode plate 200 itself.

[0085] In the specific implementation, the plate body 210 is a flat plate structure. The side of the plate body 210 is connected to one groove sidewall 222 of the fixing part 220 through a transition plate 230. Both groove sidewalls 222 of the fixing part 220 have arc-shaped wall sections 2221, and the two groove sidewalls 222 are located on both sides of the plate body 210 in the thickness direction. The thickness direction of the plate body 210 is the second direction y. With this configuration, the anode plate 200 has good structural stability, and the arc-shaped wall sections 2221 of the groove sidewalls 222 of the fixing part 220 can avoid stress concentration, which is beneficial to improving the structural strength of the anode plate 200.

[0086] The above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
