Description

Technical Field

[0001] The utility model relates to the field of electrostatic precipitators, in particular to a cathode hanging device with a porcelain-free insulating structure. Background Art

[0002] The electrostatic precipitator charges the dust by releasing ions through the discharge electrode, which then adsorbs the dust onto the collecting plate through electrostatic force. The discharge electrode, also known as the cathode, is suspended within the electric field by a hanging device and connected to a high-voltage power supply for discharge. Therefore, the cathode hanging device needs to be reliably insulated from the main structure. Currently, the industry generally uses an insulating porcelain bushing hanging device. The insulating porcelain bushing has a conical structure, with the bottom placed in the tube seat and a metal top cover on the top. Porcelain pillars are installed on both sides of the porcelain bushing, and a support beam is installed between the tops of the porcelain pillars. The cathode hanger passes through the porcelain bushing top cover and connects to the support beam, and the hanger is hung with a nut.

[0003] However, since the bottom of the hanging device is in direct contact with the flue gas in the electric field, and the upper and lower structural parts are all made of metal, during the long-term operation of the electrostatic precipitator, dust is easily attached to the wall of the porcelain bushing or condensation and creepage occur due to temperature difference, and the insulation effect is unstable. In addition, the sealing effect of the upper and lower ends of the bushing is limited, which makes it easy for external dust to enter or the flue gas inside the electric field to leak out. Therefore, the practicality of the cathode hanging structure is poor.
