Description

Technical Field

[0001] The invention relates to the field of electrostatic dust removal, and in particular to an air electrostatic dust removal device for a power distribution room. Background Art

[0002] With the rapid development of the power industry, the quality of the operating environment of the power distribution room, as an important part of the power system, has a vital impact on the normal operation and service life of power equipment. In the power distribution room, due to air circulation and equipment operation, there will inevitably be a large amount of dust and particulate matter in the air; the accumulation of dust in the power distribution room will cause many problems. First, dust will cover the surface of electrical equipment, reduce the heat dissipation efficiency of the equipment, cause the temperature of the equipment to rise, and increase the risk of failure. Secondly, dust may enter the inside of the equipment, causing poor electrical contact, short circuit and other faults, affecting the performance and reliability of the equipment. In addition, insulating components that are exposed to dusty environments for a long time are prone to reduced insulation performance, which can cause safety accidents.

[0003] When currently used in a distribution room, the existing electrostatic precipitator is not convenient to install and use in the limited space of the distribution room due to its complex structure and large size. In addition, the large size makes it very troublesome to clean and collect dust from the electrostatic precipitator, and the dust on the dust collecting electrode is not cleaned cleanly enough, thereby reducing the dust removal effect.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Embodiment: This embodiment provides an electrostatic dust removal device for air in a power distribution room, see Figure 1-6 Specifically, it includes a frame 1, a dust removal duct assembly 2, an electrostatic dust removal assembly 3, a dust collection assembly 4 and a cleaning assembly 5. Two fixing rods 11 are fixedly arranged on the inner side of the frame 1. The fixing rods 11 are used to fix multiple dust removal duct assemblies 2. The electrostatic dust removal assemblies 3 are all located in the dust removal duct assembly 2 and are used to filter dust in the air entering the dust removal duct assembly 2. The dust collection assemblies 4 are all connected to the lower side of the dust removal duct assembly 2 and are used to collect dust cleaned from the electrostatic dust removal assembly 3 by the cleaning assembly 5.

[0028] The frame 1 is installed on the ceiling of the distribution room. The frame 1 can be located at various positions on the top of the distribution room. Three dust removal duct assemblies 2 are set up. The dust removal duct assembly 2 absorbs the air in the distribution room. After the air enters the dust removal duct assembly 2, the air in the duct is dusted by the electrostatic dust removal assembly 3. When too much dust accumulates in the duct, the dust in the dust removal duct assembly 2 is cleaned into the dust collection assembly 4 by the cleaning assembly 5. Multiple dust removal duct assemblies 2 are set up, and each dust removal duct assembly 2 is equipped with an electrostatic dust removal assembly 3 and a dust collection assembly 4. Through uniform arrangement, the volume is reduced and the dust processing area is increased. The dust in the duct is quickly processed by the cleaning assembly 5, and the dust is gathered in one place, thereby improving the operating efficiency of the electrostatic dust removal assembly 3 and facilitating the rapid processing of dust.

[0029] In the specific implementation process, Figure 2 and Figure 3 As shown, the dust removal duct assembly 2 includes a plurality of transverse tubes 21 arranged transversely in the frame 1, the plurality of transverse tubes 21 are fixedly connected by two fixing rods 11, one end of the plurality of transverse tubes 21 is fixedly provided with an absorption tube 22, the opening of the absorption tube 22 is fixedly provided with an air suction fan 23, the other end of the plurality of transverse tubes 21 is connected with an exhaust tube 24, and both sides of the outlet below the transverse tube 21 are provided with inclined surfaces 8;

[0030] The transverse pipes 21 are evenly distributed in the frame 1, and the absorption pipes 22 are at ninety degrees with the transverse pipes 21. The air below the distribution room is sucked into the transverse pipes 21 through the suction fan 23 in the absorption pipes 22. After the dust in the air is processed by the electrostatic dust removal component 3 in the transverse pipe 21, the remaining air enters the exhaust pipe 24 from the transverse pipe 21, and is finally discharged from the exhaust pipe 24 into the distribution room.

[0031] In the specific implementation process, Figure 2 and Figure 3 As shown, the electrostatic precipitator assembly 3 includes a plurality of conductive rods 31 inserted in the transverse tube 21, and the conductive rods 31 are fixedly provided with discharge electrodes 32 on the outer wall of the transverse tube 21, and the top of the inner wall of the transverse tube 21 is fixedly provided with dust collecting electrodes 33;

[0032] By supplying power to the discharge electrode 32 and the dust collecting electrode 33, in the discharge area of ​​the discharge electrode 32, the positive ions are immediately attracted to the discharge electrode 32 and lose their charge, while the free electrons and the subsequently formed load ions are driven by the electric field force to move toward the dust collecting electrode 33, and finally the dust is adsorbed onto the dust collecting electrode 33, thereby realizing the treatment of dust in the air in the horizontal tube 21.

[0033] In the specific implementation process, Figure 3 and Figure 4 As shown, the dust collection assembly 4 includes a collection pipe 41 installed on the lower surface of the horizontal pipe 21, and a collection box 42 is inserted at the outlets of both ends of the collection pipe 41. A connecting piece 43 is provided between the collection box 42 and the collection pipe 41. The connecting piece 43 includes a connecting block 431 fixed to the outer wall of the collection box 42 and a connecting frame 432 fixed to the lower surface of the collection pipe 41. The connecting block 431 and the connecting frame 432 are connected by bolts.

[0034] The collecting pipe 41 is installed below the transverse pipe 21, and the top of the collecting pipe 41 is connected with the bottom of the transverse pipe 21. The dust on the dust collecting electrode 33 is cleaned into the collecting pipe 41 through the cleaning component 5, and the cleaning component 5 simultaneously cleans the dust in the collecting pipe 41 into the collecting box 42, so as to collect the dust in the pipe. The dust in the collecting box 42 can be quickly cleaned by turning the bolt to remove the collecting box 42.

[0035] In the specific implementation process, Figure 5 and Figure 6 As shown, the cleaning assembly 5 includes a moving frame 51 inserted from the ends of multiple transverse tubes 21, a plurality of L-shaped driving rods 52 are arranged side by side at one end of the moving frame 51, and a plurality of guide grooves 53 are provided on the driving rods 52. A cleaning plate 54 is fixedly provided at the other end of the moving frame 51, and the cleaning plate 54 is fitted with the bottom of the inner wall of the collecting box 42. A plurality of fixed blocks 55 are fixedly provided on the upper surface of the transverse tube 21, and L-shaped vibration blocks 56 are slidably provided on the fixed blocks 55. Rubber pads 57 are fixedly provided at the lower ends of the vibration blocks 56, and inclined surfaces are provided on both sides of the upper ends of the rubber pads 57. Springs 58 are sleeved on the vibration blocks 56. A driving member connected to the moving frame 51 is provided on the frame 1, and the driving member includes a cylinder 6, a stabilizing block 61 and a connecting rod 62. The cylinder 6 is fixedly connected to the fixed rod 11 through the stabilizing block 61, and the output end of the cylinder 6 is fixedly connected to the connecting rod 62.

[0036] The cylinder 6 drives the moving frame 51 to move back and forth, and the round rod at the end of the moving frame 51 drives the cleaning plate 54, and the cleaning plate 54 pushes the dust in the collection pipe 41 into the collection boxes 42 at both ends. The movement of the moving frame 51 also drives the driving rod 52 to move. After the inclined surface of the driving rod end 52 contacts the inclined surface of the vibration block 56, the vibration block 56 is driven to rise, so that the rubber pad 57 leaves the upper surface of the horizontal pipe 21. When the vibration block 56 moves to the guide groove 53 position on the driving rod 52, the spring 58 allows the vibration block 56 to move from the guide groove 53 position. The groove 53 moves downward quickly, and the rubber pad 57 at the lower end of the vibration block 56 contacts the transverse tube 21, causing the transverse tube 21 to vibrate. The dust on the dust collecting electrode 33 inside the transverse tube 21 falls off through the impact, and both sides of the guide groove 53 are inclined surfaces, and the vibration block 56 that has fallen will be lifted up again. By providing a plurality of guide grooves 53 and vibration blocks 56, the dust on the dust collecting electrode 33 can be quickly removed, and the fallen dust enters the collection box 42 from the transverse tube 21, and is finally collected in the collection box 42, so that the dust in the pipeline can be uniformly collected.

[0037] In the specific implementation process, Figure 1 As shown, L-shaped mounting blocks 7 are fixedly provided at the four corners of the upper surface of the frame 1; the mounting blocks 7 facilitate the mounting of the frame 1 on the ceiling.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
