Technical Field

[0001] The utility model belongs to the field of filter cartridge static elimination, in particular to an anti-static filter cartridge static elimination device. Background Art

[0002] The working principle of the anti-static coated filter cartridge can be simply described as: when the particles in the air pass through the filter cartridge, the coating layer will quickly conduct static electricity to the ground, thereby avoiding the accumulation and discharge of static electricity. In this way, the filter cartridge can effectively filter the particles in the air while maintaining the conductive properties of the filter cartridge surface, ensuring that static electricity can be conducted to the ground in a timely manner without causing harm to the working environment and equipment. However, there are some difficult to solve problems with ordinary anti-static filter cartridges: 1. Ordinary anti-static filter cartridges usually conduct static electricity to the ground, and sparks will be generated during the discharge process, which poses a safety hazard to oil fields, chemical plants, etc., such as fires and explosions.
