Description

Technical Field

[0001] This utility model relates to the field of electrostatic precipitator technology, and in particular to an RS line for an electrostatic precipitator. Background Technology

[0002] An electrostatic precipitator (ESP) is a high-efficiency dust removal device that uses electrostatic force to separate dust from gas. The RS wire is one of the commonly used cathode wires in ESPs. Existing RS wires are manufactured separately from the toothed section and the tube blank. For example, Chinese patent application CN201755527U discloses an improved RS wire for ESPs, which is welded together from the toothed section and the tube blank with connecting holes. The toothed section is made of thin steel plate, with a partially rhomboid shape in plan view, and four small teeth cut at the tip, staggered outwards to both sides. The tube blank is made of strip steel rolled into a semi-circular arc blank with flanges on both sides, and then welded together. After welding, the ends and connecting holes are stamped. However, because various corrosive gases and dusts are usually present inside ESPs, the toothed section in the above-mentioned RS wire is susceptible to the corrosive environment, resulting in cracks or breakage, thus reducing the dust removal efficiency of the ESP. Utility Model Content

[0003] To address the aforementioned technical problem of cracks or fractures in the filaments, this invention provides an RS wire for an electrostatic precipitator that isolates the connection point between the filaments and the tube blank from the corrosive environment, thereby improving the durability of the filaments and ensuring the stable and efficient operation of the electrostatic precipitator.

[0004] The specific technical solution of this utility model is as follows: an RS line for an electrostatic precipitator, comprising a first half blank, a second half blank, and a plurality of serrations. The first half blank and the second half blank are stacked and connected to form a tube blank. The tube blank includes a tube blank body, connecting portions located at both ends of the tube blank body, and side portions located on the side of the tube blank body. The side portions are formed by stacking the first side of the first half blank and the second side of the second half blank. A plurality of serrations are spaced apart on the side portions. Each serration includes a fixing portion and a discharge portion. The first side and the second side cover the fixing portion of the serrations.

[0005] In the above technical solution, the teeth are connected to the tube blank through the fixing part. The fixing part is covered by the first side and the second side to form a tight protective structure, which reduces the direct contact between the corrosive gas and dust inside the electrostatic precipitator and the fixing part, and reduces the risk of the teeth cracking or breaking due to corrosion. The discharge part of the teeth is located outside the tube blank, ensuring that its tip discharge characteristics can be fully utilized in the electric field to continuously and efficiently generate corona discharge, thus ensuring the stable and efficient operation of the electrostatic precipitator.

[0006] Preferably, the fixing part is welded to the first side; and / or, the fixing part is welded to the second side.

[0007] In the above technical solution, the fixing part is welded to at least one side, which has a high connection strength and ensures a reliable connection between the teeth and the tube blank. At the same time, the teeth are fixed in position, which can resist airflow impact and mechanical vibration during the operation of the electrostatic precipitator and prevent them from falling out of the predetermined position, thereby ensuring stable and efficient discharge.

[0008] Preferably, the first side and the second side clamp and fix the fixing part.

[0009] In the above technical solution, the connection between the tooth and the tube blank can be completed simply by placing the fixing part between the two sides and pressing the two sides together. The connection is simple and quick.

[0010] Preferably, the toothed part further includes a bent part disposed at one end of the fixing part near the tube blank body, the bent part being disposed within the tube blank body and abutting against the inner wall of the tube blank body.

[0011] In the above technical solution, the contact between the bent part and the inner wall of the tube blank prevents the serrations from shifting outward and leaving the predetermined position, thereby ensuring stable and efficient discharge; the bent part can evenly distribute the external force and avoid stress concentration at the connection point between the fixed part and the tube blank.

[0012] Preferably, the side portion is provided with a plurality of mounting slots that are adapted to the fixing portion, and the fixing portion is installed in the corresponding mounting slot.

[0013] In the above technical solution, the installation groove provides a positioning reference for the tooth, making it easy for operators to quickly find the correct position when inserting the tooth. At the same time, compared with the fixing part being directly connected to the inner wall of the side part, the installation groove leaves more space for the fixing part in the thickness direction, so that the thickness of the fixing part can be designed to be thicker, thereby improving the bending and deformation resistance of the fixing part itself.

[0014] Preferably, the mounting groove is formed by bending a portion of the structure on the first side away from the second side; or, a portion of the structure on the first side is bent away from the second side to form a first half-groove, and a portion of the structure on the second side is bent away from the first side to form a second half-groove, with the first half-groove and the corresponding second half-groove together forming the mounting groove.

[0015] In the above technical solution, the integrally formed mounting groove and the side structure form a continuous mechanical transmission path, which enhances the wrapping and support force of the side on the fixing part and optimizes the overall structural strength.

[0016] Preferably, the discharge section is provided with a curved discharge tip, and at least one of the curved discharge tips is close to the end of the side portion away from the tube blank body.

[0017] In the above technical solution, the bent discharge tip that is close to the side forms a limiting structure, which effectively avoids the risk of the tooth shrinking into the tube blank; in addition, the close fit between the tip and the side can also disperse the external force to the entire RS wire frame through the side structure, further improving the positional stability of the tooth and ensuring that it always maintains a precise discharge distance during long-term operation.

[0018] Preferably, the teeth are integrally stamped; and / or, the first half-blank and the second half-blank are integrally stamped.

[0019] Compared to a split structure, the integrated stamping structure eliminates the need for separate processing and assembly of multiple parts, reducing processing steps and assembly time, resulting in high production efficiency. Furthermore, the integrated stamping avoids gaps between parts, eliminating potential stress concentration and weakness at connection points, thus enhancing structural strength.

[0020] Preferably, multiple serrations on the same side are spaced apart along the length of the tube blank.

[0021] In the above technical solution, the serrations are spaced apart along the length of the tube blank, which facilitates precise control of the discharge distance and prevents short circuits caused by excessively close distance between adjacent serrations. At the same time, it can make the electric field distribution inside the electrostatic precipitator more uniform and improve the dust removal effect of the electrostatic precipitator.

[0022] Preferably, the two opposite sides of the tube blank are provided with multiple serrations, and the serrations on the two sides are staggered.

[0023] In the above technical solution, due to the staggered arrangement of the two side teeth, the electric field forms an interlaced force field distribution in space. During the movement of dust, it will be subjected to electric field forces in multiple directions, thereby improving the dust collection efficiency.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] (1) Good durability of the teeth: The teeth are connected to the tube blank through the fixing part. The fixing part is covered by the first side and the second side to form a tight protective structure, which reduces the direct contact between the corrosive gas and dust inside the electrostatic precipitator and the fixing part, and reduces the risk of the teeth cracking or breaking due to corrosion. In addition, the fixing part is installed in the mounting groove, which allows the thickness of the fixing part to be designed to be thicker, so as to improve the bending and deformation resistance of the fixing part itself.

[0026] (2) Good dust removal effect: The position of the teeth is fixed and the teeth on the two sides are staggered. The electric field forms an interlaced force field distribution in space. The dust will be subjected to electric field forces in multiple directions during the movement, which improves the dust collection efficiency. Attached Figure Description

[0032] The present invention will be further described below with reference to embodiments. Unless otherwise specified, all devices, connection structures, and methods involved in this invention are known in the art.

[0033] Example 1

[0034] Reference Figures 1 to 4 As shown, this utility model provides an RS wire for an electrostatic precipitator, including a first half-blank 1, a second half-blank 2, and a plurality of teeth 4. The first half-blank 1 and the second half-blank 2 are stacked and welded to form a tube blank 3. The tube blank 3 includes a hollow tube blank body 6, connecting portions 5 located at both ends of the tube blank body 6, and side portions 7 located on the sides of the tube blank body 6. The side portions 7 are formed by stacking and welding the first side portion 71 of the first half-blank 1 and the second side portion 72 of the second half-blank 2. A plurality of teeth 4 are spaced apart on the side portions 7. Each tooth 4 includes a fixing portion 41 and a discharge portion 42. The first side portion 71 and the second side portion 72 cover the fixing portion 41 of the tooth 4, and the discharge portion 42 extends out of the tube blank 3.

[0035] In the aforementioned RS line of the electrostatic precipitator, the tooth 4 is connected to the tube blank 3 through the fixing part 41. The fixing part 41 is covered by the first side 71 and the second side 72 to form a tight protective structure, which effectively isolates the corrosive gas and dust inside the electrostatic precipitator from direct contact with the fixing part 41, reducing the risk of the tooth 4 cracking or breaking due to corrosion. The discharge part 42 of the tooth 4 is located outside the tube blank 3, ensuring that its tip discharge characteristics can be fully utilized in the electric field to continuously and efficiently generate corona discharge, ensuring the stable and efficient operation of the electrostatic precipitator.

[0036] In the aforementioned RS line of the electrostatic precipitator, the production of the tooth 4 follows the traditional method of separate welding of the tooth 4, that is, it is made by stamping and forming the strip steel material separately using a punch press. If it is welded on an automated production line, the forming of the tooth 4 can be completed by the automated line. The production of the tube blank 3 involves first rolling the strip steel material into a first half-blank 1 and a second half-blank 2 with two flanged sides. The flanged sides of the first half-blank 1 are the first side 71, and the flanged sides of the second half-blank 2 are the second side 72. After the first half-blank 1 and the second half-blank 2 are welded together, the two ends are stamped to form the connecting part 5. Alternatively, the tube blank 3 can also be produced by separate welding, using an independent connecting pipe as the connecting part 5. The tube blank body and the connecting pipe are made separately first, and then welded together after each part is made.

[0037] Example 2

[0038] This utility model provides an RS wire for an electrostatic precipitator. The tooth 4 is connected to the side portion 7 by welding. There are three connection methods: first, the fixing part 41 of the tooth 4 is welded only to the first side portion 71; second, the fixing part 41 is welded only to the second side portion 72; and third, the fixing part 41 is welded to both the first side portion 71 and the second side portion 72. Welding the fixing part 41 to the side portion 7 provides a strong connection, ensuring a reliable connection between the tooth 4 and the tube blank 3. At the same time, the fixed position of the tooth 4 can resist airflow impact and mechanical vibration during the operation of the electrostatic precipitator, preventing it from falling out of its predetermined position, thereby ensuring stable and efficient discharge.

[0039] In another embodiment, the first side 71 and the second side 72 clamp the fixing part 41, so that the tooth 4 is fixedly connected to the side part 7. Compared with welding, this connection method only requires placing the fixing part 41 between the two sides and pressing the two sides together to complete the connection between the tooth 4 and the tube blank 3, which is simple and quick.

[0040] Reference Figure 3 The tooth 4 also includes a bent portion 43 disposed at one end of the fixing portion 41 near the tube blank body 6. The bent portion 43 is bent relative to the fixing portion 41, forming an angle between them. The bent portion 43 is disposed inside the tube blank body 6 and abuts against the inner wall of the tube blank body 6. By abutting against the inner wall of the tube blank body 6, the tooth 4 is prevented from shifting outward and leaving the predetermined position, thereby ensuring stable and efficient discharge. The bent portion 43 can evenly distribute external forces and avoid stress concentration at the connection point between the fixing portion 41 and the tube blank.

[0041] Furthermore, the bending part 43 and the fixing part 41 form a 90° angle, and the bending part 43 fits against the inner wall of the tube blank body 6. This not only enhances the limiting ability of the tooth 4, but also further improves the effect of dispersing external forces, so that the tooth 4 can work more stably under the complex working conditions of the electrostatic precipitator, providing a strong guarantee for the long-term stable operation of the electrostatic precipitator.

[0042] Reference Figure 2 and 3 In one embodiment of the present invention, the planar projection of the discharge section 42 is partially rhomboid in shape, and it is provided with four curved discharge tips 44. These discharge tips 44 are staggered and turned outward on both sides, with the curved position of one of the discharge tips 44 close to the end of the side portion 7 away from the tube blank body 6. The curved discharge tip 44 close to the side portion 7 forms a limiting structure. For example, when the fixing part 41 is clamped and connected to the side portion 7, it can effectively avoid the risk of the tooth 4 retracting into the tube blank 3. In addition, the close contact between the tip and the side portion 7 can also disperse the external force to the entire RS wire frame through the side structure, further improving the positional stability of the tooth 4 and ensuring that it always maintains a precise discharge distance during long-term operation.

[0043] Reference Figure 3 Multiple teeth 4 on the same side 7 are spaced apart along the length of the tube blank 3. The spacing of the teeth 4 along the length of the tube blank 3 facilitates precise control of the discharge distance and prevents short circuits caused by adjacent teeth 4 being too close. At the same time, it makes the electric field distribution inside the electrostatic precipitator more uniform and improves the dust removal effect of the electrostatic precipitator.

[0044] Furthermore, each of the two oppositely positioned side portions 7 of the tube blank 3 is provided with multiple serrations 4, which are staggered. Due to the staggered arrangement of the serrations 4 on the two side portions 7, the electric field forms an interlaced force field distribution in space. During the dust's movement, it will be subjected to electric field forces in multiple directions, thereby improving the dust collection efficiency.

[0045] Reference Figure 2 The side portion 7 is provided with multiple mounting slots 8 that are adapted to the fixing part 41. The fixing part 41 is installed in the corresponding mounting slot 8. That is, the fixing part 41 is installed in the corresponding mounting slot 8 on the side portion 7 according to the distribution of the teeth 4 on the side portion 7, such as the number of teeth 4 and the spacing distance. The mounting slots 8 provide a positioning reference for the teeth 4, making it easy for the operator to quickly find the correct position when inserting the teeth 4. At the same time, compared with the fixing part 41 being directly connected to the inner wall of the side portion 7, the mounting slots 8 leave more space for the fixing part 41 in the thickness direction, so that the thickness of the fixing part 41 can be designed to be thicker, thereby improving the bending and deformation resistance of the fixing part 41 itself.

[0046] The mounting groove 8 can be formed by either single-sided bending or double-sided enclosing. Single-sided bending involves bending a portion of the structure on the first side 71 away from the second side 72, or bending a portion of the structure on the second side 72 away from the first side 71. Double-sided enclosing involves bending a portion of the structure on the first side 71 away from the second side 72 to form a first half-groove, and bending a portion of the structure on the second side 72 away from the first side 71 to form a second half-groove. The first half-groove and the corresponding second half-groove together form the mounting groove 8. The one-piece molded mounting groove 8 forms a continuous mechanical transmission path with the side structure, which enhances the wrapping and support force of the side on the fixing part 41 and optimizes the overall structural strength. Compared with the mounting groove 8 being a split structure installed on the side part 7, the one-piece molded mounting groove 8 avoids splicing gaps, reduces the direct contact between corrosive gases and dust inside the electrostatic precipitator and the fixing part 41, and reduces the risk of the teeth 4 cracking or breaking due to corrosion.

[0047] In this embodiment, the tooth 4, the first half-blank 1, and the second half-blank 2 are integrally stamped structures. Compared with a split structure, the integral stamped structure does not require multiple parts to be processed and reassembled separately, reducing processing steps and assembly time, resulting in high production efficiency. Furthermore, integral stamping avoids the generation of gaps between parts, eliminating problems such as stress concentration and weak strength that may occur at the connection points, thereby enhancing structural strength.

[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, alterations, or equivalent structural transformations made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
