Description

Technical Field

[0001] This utility model relates to the field of electrostatic precipitator technology, specifically to an electrostatic precipitator labyrinth-type insulating board with a blowing function. Background Technology

[0002] High-efficiency dust removal equipment, such as electrostatic precipitators, wet electrostatic precipitators, and dry electrostatic precipitators, is widely used in industrial flue gas purification. The core high-voltage components of these devices typically operate at voltages as high as 50kV or even higher, placing extremely stringent requirements on the performance of critical insulation components. Among these, the insulating plate (or insulator box, insulator chamber), used to support the high-voltage electrodes and isolate the high-voltage area from the grounding section, not only provides stable electrical insulation but also serves a sealing function, preventing the high-temperature, dust-laden, and moist flue gas from rising and contaminating the high-voltage porcelain insulators (or insulating bushings) above.

[0003] Under actual operating conditions, the following problems arise when insulating boards are exposed to harsh environments for extended periods: 1. Fine dust particles, tar, acid mist, and other pollutants carried in flue gas easily deposit and adhere to the surface and crevices of the insulating board; 2. The combined effect of dust accumulation and moisture significantly reduces the insulation resistance of the insulating board surface and forms local conductive paths, thereby inducing creepage (flashover) phenomena along the insulating board surface; 3. Repeated creepage generates localized high temperatures, leading to irreversible carbonization of the insulating material, ultimately causing high-voltage short circuits or grounding faults, forcing the entire electrostatic precipitator to shut down for maintenance. Therefore, this application provides a labyrinth-type insulating board for electrostatic precipitators with a purging function to solve the above problems. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome existing defects and provide an electrostatic precipitator labyrinth-type insulating board with a blowing function. Hot air is blown into the labyrinth groove through through-holes in the insulating board, preventing flue gas and pollutants from rising and contaminating the insulating board. This also ensures the insulating board remains dry and prevents moisture and dust from adhering to and contaminating it, thus guaranteeing the insulating board's insulation performance and preventing creepage. This ensures the long-term stable operation of the environmental protection equipment, is easy to use, and effectively solves the problems in the background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an electrostatic precipitator labyrinth-type insulating board with a blowing function, comprising an insulating board, wherein a cavity is formed on the upper surface of the insulating board, and a plurality of labyrinth grooves arranged in a ring are formed on the bottom of the insulating board, wherein uniformly distributed through holes are formed at the positions corresponding to the cavity and the labyrinth groove, and a hot air pipe is provided on the side of the insulating board corresponding to the cavity.

[0006] As a preferred embodiment of this utility model, the insulating plate has a mounting hole in the middle for mounting a cathode hanger.

[0007] As a preferred embodiment of this utility model, the insulating plate is a circular plate structure composed of two semi-circular insulating plates.

[0008] As a preferred embodiment of this utility model, the insulating board is a polytetrafluoroethylene insulating board.

[0009] As a preferred embodiment of this utility model, the upper surface edge of the insulating plate is provided with uniformly distributed fixing holes.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figs. 1-3This utility model provides a technical solution: an electrostatic precipitator labyrinth-type insulating board with a blowing function, including an insulating board 1. A cavity 3 is formed on the upper surface of the insulating board 1, and a plurality of labyrinth grooves 5 arranged in a ring are formed on the bottom of the insulating board 1. The cross-section of the labyrinth grooves 5 is a "7" shaped structure. The cavity 3 and the corresponding part of the labyrinth grooves 5 are provided with uniformly distributed through holes 6, and the side of the insulating board 1 corresponding to the cavity 3 is provided with a hot air pipe 4. The air outlet pipe of the external hot air system is connected to the hot air pipe 4. Hot air enters into the cavity 3 and is discharged downward from the labyrinth grooves 5 through the through holes 6, so that positive pressure is generated below the insulating board 1 to prevent the flue gas from rising and contaminating the insulating board 1. At the same time, when the hot air blows downward from the labyrinth grooves 5, it can prevent dust particles and water vapor from sticking in the gaps of the labyrinth grooves 5 and reducing the insulation performance of the insulating board 1.

[0018] Furthermore, the insulating plate 1 has a mounting hole 2 in the middle for installing the cathode hanger.

[0019] Furthermore, the insulating plate 1 is a circular plate structure composed of two semi-circular insulating plates. The two semi-circular insulating plates are installed on both sides of the cathode hanger rod of the porcelain insulator box, and then assembled into a circular insulating plate 1 by bonding.

[0020] Furthermore, the insulating board 1 is a polytetrafluoroethylene insulating board.

[0021] Furthermore, the upper surface edge of the insulating plate 1 is provided with evenly distributed fixing holes 7, which facilitates the installation and fixing of the insulating plate 1.

[0022] This invention uses the through holes 6 on the insulating plate 1 to blow hot air into the labyrinth groove 5, preventing smoke and pollutants from rising and contaminating the insulating plate 1. It also ensures that the insulating plate 1 is dry and prevents moisture and dust from adhering to and contaminating the insulating plate 1, thus ensuring the insulation performance of the insulating plate 1 and avoiding creepage. This ensures the long-term stable operation of the environmental protection equipment and makes it easy to use.
