Description

Technical Field

[0001] This utility model relates to a novel cathode wire for an electrostatic precipitator. Background Technology

[0002] The design of the cathode wire in an electrostatic precipitator must not only meet the required current but also pay attention to its strength and rigidity. Currently, the cathode wires used in electrostatic precipitators on the market generate an electric field within the precipitator housing when the cathode wire is connected to a negative high-voltage power supply, due to their relatively weak overall rigidity. In actual use, they are prone to breakage, and "breakage" often accounts for a large proportion of electrostatic precipitator failures. In addition, the number of discharge spikes is reduced to ensure the rigidity of the cathode wire body, which is not conducive to optimizing electrical discharge performance, resulting in low discharge efficiency and affecting the dust removal effect. Therefore, a cathode wire that is not prone to breakage and can improve discharge efficiency is needed for efficient dust removal. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a novel cathode wire for electrostatic precipitators.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A novel cathode wire for an electrostatic precipitator includes a seamless steel pipe, several cathode assemblies mounted on the seamless steel pipe, and expansion bolts that pass through the cathode assemblies and are fixed to the seamless steel pipe. The seamless steel pipe includes a seamless steel pipe body, wiring terminals integrally formed at both ends of the seamless steel pipe body, and several mounting holes opened on the seamless steel pipe body. The cathode assembly includes an arc-shaped fastening part, a through hole opened at the center of the arc-shaped fastening part, and a first barb and a second barb symmetrically arranged at both ends of the arc-shaped fastening part.

[0006] Preferably, the surface of the seamless steel pipe body is also provided with a spiral guide wire, and the mounting holes are equidistantly distributed along the extension direction of the spiral guide wire.

[0007] Preferably, the axis of the mounting hole is perpendicular to the tangent direction of the helical wire, and the spacing between all mounting holes is equal.

[0008] Preferably, the curvature of the inner wall of the arc-shaped fastening part of the cathode assembly matches the curvature of the outer wall of the seamless steel pipe body, so that the arc-shaped fastening part is attached to the surface of the seamless steel pipe body by clamping.

[0009] Preferably, the tips of the first and second barbs extend outward and are centrally symmetrically distributed to form a double-barb discharge structure.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. The use of seamless steel pipes as the main support structure provides higher mechanical strength and corrosion resistance. The design of the seamless steel pipe body ensures the stability of the cathode wire and the reliability of long-term use, while expansion bolts are used to fix the cathode assembly, ensuring that the assembly will not loosen during use, thus enhancing the reliability of the entire equipment;

[0012] 2. The cathode assembly design uses a first barb and a second barb, with the tips distributed in a centrally symmetrical manner to form a double-barb discharge structure. This design helps to improve discharge efficiency and enhance the working effect of the electrostatic precipitator. In addition, the optimization of the discharge structure can make the electrostatic precipitator more efficient when dealing with high voltage or strong electric fields, thereby improving its dust removal capacity.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0017] Example

[0018] A novel cathode wire for electrostatic precipitators, such as Figure 1-3 As shown, the device includes a seamless steel pipe 1, several cathode components 2 mounted on the seamless steel pipe 1, and expansion bolts 3 that pass through the cathode components 2 and are fixed to the seamless steel pipe 1. The seamless steel pipe 1 includes a seamless steel pipe body 11, wiring terminals 12 integrally formed at both ends of the seamless steel pipe body 11, and several mounting holes 13 opened on the seamless steel pipe body 11. The cathode component 2 includes an arc-shaped fastening part 21, a through hole 22 opened at the center of the arc-shaped fastening part 21, and a first barb 23 and a second barb 24 symmetrically arranged at both ends of the arc-shaped fastening part 21.

[0019] The seamless steel pipe body 11 also has a spiral guide wire 111 on its surface, and mounting holes 13 are equidistantly distributed along the extension direction of the spiral guide wire 111. Specifically, the equidistant distribution of mounting holes 13 along the extension direction of the spiral guide wire 111 ensures the uniform distribution of the cathode assembly, thereby making the discharge effect of the entire electrostatic precipitator more balanced, avoiding uneven current distribution, and improving efficiency. Moreover, the spiral guide wire design can effectively guide the current and reduce possible electrical interference, improving the electrical performance of the electrostatic precipitator.

[0020] The axis of the mounting holes 13 is perpendicular to the tangent direction of the helical wire 111, and the spacing between all mounting holes 13 is equal. Specifically, the fact that the axis of the mounting holes 13 is perpendicular to the tangent direction of the helical wire 111 and the spacing between all mounting holes makes the installation of the cathode assembly more precise and reduces errors and unevenness.

[0021] The inner curvature of the arc-shaped fastening part 21 of the cathode assembly 2 matches the curvature of the outer wall of the seamless steel pipe body 11, allowing the arc-shaped fastening part 21 to be snapped onto the surface of the seamless steel pipe body 11. Specifically, the matching of the inner curvature of the arc-shaped fastening part 21 of the cathode assembly 2 with the curvature of the outer wall of the seamless steel pipe body 11 ensures a tight fit of the snap-fit ​​structure, enabling the cathode assembly to be stably fixed to the steel pipe without loosening or falling off. Moreover, through the snap-fit ​​design, the cathode assembly can be installed quickly and securely, reducing the difficulty and time in the assembly process and further improving production efficiency.

[0022] The tips of the first barb 23 and the second barb 24 extend outwards and are centrally symmetrically distributed, forming a double-barb discharge structure. Specifically, the outward extension and centrally symmetrical distribution of the tips of the first barb 23 and the second barb 24, forming a double-barb discharge structure, helps to enhance the discharge capacity of the current and improve the discharge effect of the electrostatic precipitator. Furthermore, it increases the stability of the discharge, making the electric field distribution more uniform, thereby improving the overall working efficiency of the electrostatic precipitator and ultimately enhancing the dust removal effect.

[0023] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
