Abstract
Description
Technical Field
[0001] This utility model relates to a barbed corona wire for an electrostatic precipitator. Background Technology
[0002] As is well known, the corona wire is a core component of an electrostatic precipitator. It utilizes the discharge electrode corona wire and the collecting electrode plates to create a strong collecting electric field, charging the dust particles and allowing them to be captured by the collecting plates. The structure and shape of the corona wire directly affect the volt-ampere characteristics and dust collection efficiency of the electrostatic precipitator. Therefore, since the invention of the electrostatic precipitator, researchers have continuously studied and designed new corona wires in hopes of improving its performance and increasing its dust collection efficiency.
[0003] Utility model patent CN2160471Y discloses a new structure of corona wire. This document describes its advantages, including high mechanical strength, resistance to breakage, easy cleaning, low cost, and simple manufacturing. It is suitable for use in new electrostatic precipitators or for retrofitting older ones. However, this structure has the following problems in practical use: First, the corona discharge efficiency is low. Because the barbs are cut and bent from corresponding positions on both sides of the corona wire body, although the structure is stable, it only has a single discharge end, which cannot reduce the uneven electric shock caused by electric field concentration, thus reducing discharge efficiency. Second, the uneven electric shock weakens the electric field strength, making it difficult for the electrostatic precipitator to efficiently remove dust and impurities from the air, thus affecting the dust removal effect and hindering the reduction of pollutant emissions. Utility Model Content
[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a barbed corona wire for an electrostatic precipitator.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] A barbed corona wire for an electrostatic precipitator includes an angle steel busbar, connecting ends fixed at both ends of the angle steel busbar, and downward-sloping barbs and upward-folding barbs equidistantly fixed on both sides of the angle steel busbar. The downward-sloping barbs and upward-folding barbs are staggered. The downward-sloping barb includes a barb body, a fastening part located at the lower end of the barb body and bent outward, a fixing screw set on the barb body and close to the fastening part, a main discharge end integrally formed with the barb body and not bent, a first auxiliary discharge end and a second auxiliary discharge end located on both sides of the main discharge end and bent in different directions, a first side discharge end located on one side of the middle of the barb body and bent in the same direction as the second auxiliary discharge end, and a second side discharge end located on the other side of the middle of the barb body and bent in the same direction as the first auxiliary discharge end.
[0007] Preferably, the first and second auxiliary discharge ends are based on the barb body as the reference plane, and their bending angles are both 45°.
[0008] Preferably, the first discharge end and the second discharge end are based on the barb body as the reference plane, and their bending angles are both 90°.
[0009] Preferably, the upward-folded barb is formed by bending the barb body of the downward-sloping barb of the same structure vertically upward at 90° near the fastening part, and the upward-folded barb and the downward-sloping barb form a 90° angle.
[0010] Preferably, the two sides of the angle steel busbar are bent inward to form an inner hook. The inner hook has threaded holes corresponding to the fastening parts of the downward sloping barb and the upward folded barb. The barb is fixed by screwing the fixing screws into the threaded holes and the barb body in sequence.
[0011] Furthermore, after the inner hook and the fastening part are engaged, the fixing screw tightens the fastening part to enhance the connection stability.
[0012] The beneficial effects of this utility model are as follows:
[0013] 1. High-efficiency corona discharge: The staggered distribution of downward-sloping and upward-folding barbs makes the corona discharge more uniform, reduces the uneven electric shock caused by electric field concentration, and improves the discharge efficiency. By setting the bending angles of 45° and 90°, the electric field distribution is optimized, enhancing the intensity and stability of the corona discharge.
[0014] 2. Enhanced stability and connection reliability: The inner hooks on both sides of the angle steel busbar are fastened to the fastening parts and fixed with fixing screws to ensure a firm connection of each part. This avoids failures or reduced efficiency caused by loosening or vibration. The fixing screws tighten the fastening parts, further increasing the stability of the connection and preventing the possible loosening or vibration from affecting the corona wire.
[0015] 3. Improved dust removal efficiency: The improved discharge design effectively enhances the electric field strength, enabling the electrostatic precipitator to remove dust and impurities from the air more efficiently, thereby improving the dust removal efficiency and reducing pollutant emissions.

[0021] 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.
[0022] Example
[0023] A type of barbed corona wire for an electrostatic precipitator, such as Figure 1-5 As shown, it includes an angle steel busbar 1, connecting ends 2 fixed at both ends of the angle steel busbar 1, and downward oblique barbs 3 and upward folded barbs 4 fixedly installed at equal intervals on both sides of the angle steel busbar 1. The downward oblique barbs 3 and upward folded barbs 4 are staggered, which can make the corona discharge more uniform, reduce the uneven electric shock caused by electric field concentration, and improve the discharge efficiency.
[0024] The downward-sloping spike 3 includes a spike body 31, a fastening part 32 located at the lower end of the spike body 31 and bent outward, a fixing screw 33 disposed on the spike body 31 and close to the fastening part 32, a main discharge end 34 integrally formed with the spike body 31 and not bent, a first auxiliary discharge end 35 and a second auxiliary discharge end 36 located on both sides of the main discharge end 34 and bent in different directions, a first side discharge end 37 located on one side of the middle of the spike body 31 and bent in the same direction as the second auxiliary discharge end 36, and a second side discharge end 38 located on the other side of the middle of the spike body 31 and bent in the same direction as the first auxiliary discharge end 35.
[0025] In this embodiment, the first auxiliary discharge end 35 and the second auxiliary discharge end 36 are based on the thorn body 31, and their bending angles are both 45°.
[0026] In this embodiment, the first discharge end 37 and the second discharge end 38 are based on the thorn body 31, and their bending angles are both 90°.
[0027] Therefore, by setting bending angles of 45° and 90°, the electric field distribution was optimized, enhancing the intensity and stability of corona discharge.
[0028] The upward-folded barb 4 is formed by bending the barb body 31 of the downward-sloping barb 3, which has the same structure, vertically upward at 90° near the fastening part 32. The upward-folded barb 4 and the downward-sloping barb 3 form a 90° angle.
[0029] The two sides of the angle steel busbar 1 are bent inward to form an inner hook 11. The inner hook 11 is provided with a threaded hole 12 corresponding to the fastening part of the downward sloping barb 3 and the upward folded barb 4. The barb body 31 is fixed by screwing the fixing screw 33 into the threaded hole 12 and the barb body 31 in sequence.
[0030] After the inner hook part 11 is engaged with the fastening part 32, the fixing screw 33 tightens the fastening part 32 to enhance the connection stability. Specifically, the inner hook parts 11 on both sides of the angle steel busbar 1 are fastened to the fastening part 32, and then fixed with the fixing screw 33 to ensure a firm connection of each part, avoiding failures or reduced efficiency caused by loosening or vibration. The fixing screw 33 tightens the fastening part 32, further increasing the stability of the connection and preventing the possible loosening or vibration from affecting the corona wire.
[0031] It should be further explained that the angle of the angle steel busbar 1 faces upward, which is not conducive to the accumulation of dust during actual use, and the dust can be quickly shaken off by the tapping device.
[0032] 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.
