They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] Example: Please see Figure 1-4 This utility model provides a technical solution: An electrostatic precipitator structure for a railway air conditioning system includes a filter box 1. The front end of the filter box 1 has an inspection port, and a sealing plate 2 is fixed inside the inspection port. When it is necessary to inspect the internal structure of the filter box 1, the sealing plate 2 can be opened. The upper and lower sides of the inner wall of the filter box 1 are fixed with clamping plates 3. An electrostatic filter 4 is fixed between the two clamping plates 3. Symmetrical inspection lights 5 are fixed at the upper end of the inner wall of the filter box 1. During the inspection process, the inspection lights 5 can be turned on to increase the internal brightness and facilitate the inspection. A first connecting flange pipe 6 is fixed to the left side of the filter box 1, and the first connecting flange pipe 6 is connected and fixed to the air outlet pipe of the air conditioner. A second connecting flange pipe 7 is fixed to the right side of the filter box 1, and the second connecting flange pipe 7 is used to discharge the filtered airflow. A fan 8 is fixed to the lower inner wall of the filter box 1 at the right end of the electrostatic filter 4. A canvas flexible connector 9 is fixed to the air outlet end of the fan 8. The right end of the canvas flexible connector 9 is fixedly connected to the pipe opening of the second connecting flange pipe 7. The canvas flexible connector 9 mainly plays the role of noise reduction, compensation of pipeline displacement, and vibration absorption in the electrostatic dust removal structure of the railway air conditioning system. Its working principle is to absorb vibration and balance pipeline deviation through flexible material, reduce noise and vibration caused by fan operation or pipeline deformation, and adapt to pipeline deformation caused by temperature changes.

[0018] The left and right front ends of the filter box 1 are both threaded with the first bolt. The sealing plate 2 is fixedly connected to the inspection port by the first bolt. When it is necessary to inspect the inside of the filter box 1, the sealing plate 2 can be removed.

[0019] The left and right sides of the two clamping plates 3 are threaded with second bolts. The electrostatic filter 4 is fixedly connected to the clamping plates 3 by the second bolts. When the filtration effect of the electrostatic filter 4 decreases after long-term use, it is convenient to disassemble the electrostatic filter 4.

[0020] A storage box 10 is fixed to the upper side of the filter box 1. The front end of the storage box 10 is connected to the first door 11 by a hinge. The left and right sides of the inner wall of the storage box 10 are fixed with evenly arranged first placement racks 12. A spare electrostatic filter 13 is horizontally clipped into the inside of the storage box 10 by the first placement racks 12. In order to prevent the electrostatic precipitator structure from becoming unusable after the electrostatic filter 4 inside the filter box 1 is removed, a spare electrostatic filter 13 is installed inside the storage box 10 to ensure that the electrostatic precipitator structure can be used continuously.

[0021] A drying box 14 is fixed to the right side of the storage box 10. The front end of the drying box 14 is connected to a second door 15 via a hinge. A second placement rack 16 is fixed to the left and right sides of the inner wall of the drying box 14. An electrostatic filter 17 to be dried is horizontally clipped between the two second placement racks 16. An installation tube 18 is fixed to the upper side of the drying box 14. A drying hood 19 is fixed to the lower end of the installation tube 18. A fan 20 is fixed inside the installation tube 18. A filter screen 21 is fixed to the upper end of the installation tube 18. A water collection tank 22 is provided at the lower end of the interior of the drying box 14. After the disassembled electrostatic filter 4 is manually cleaned, it is installed inside the drying box 14. The filter components inside are quickly dried by airflow. After drying, it is placed back inside the storage box 10 for later use.

[0022] Symmetrical mounting brackets are fixed to the lower side of filter box 1.

[0023] Working principle: When the electrostatic precipitator structure is needed, start the fan 8. The fan 8 draws outside air into the filter box 1 through the first connecting flange pipe 6. The air is filtered, sterilized and disinfected by the internal electrostatic filter 4, and odors are effectively removed. After the air is treated, it is discharged through the second connecting flange pipe 7. After a period of use, the air treatment effect of the electrostatic filter 4 will decrease due to prolonged use. At this time, the sealing plate 2 on the front side of the filter box 1 can be opened, and the second bolt on the side wall of the clamping plate 3 can be removed. The electrostatic filter 4 can be disassembled from the inspection port. In order not to affect the continued use of the electrostatic dust removal structure, a spare electrostatic filter 13 can be taken out from the inside of the storage box 10. The spare electrostatic filter 13 is installed and fixed inside the two clamping plates 3. After the sealing plate 2 is fixed, the electrostatic dust removal structure can continue to be used. The disassembled electrostatic filter 13 is manually disassembled, and the internal filter screen and other filter structures are manually cleaned. After cleaning, it is reassembled and restored to its original state. The electrostatic filter 13 is then installed and fixed inside the drying box 14. The fan 20 is turned on, and the fan 20 discharges the airflow through the drying hood 19 to dry it. After drying, it is placed inside the storage box 10 for later use.
