Description

Technical Field

[0001] The utility model relates to the technical field of industrial waste gas filtering, in particular to a filtering device for high-voltage electrostatic dust collection. Background Art

[0002] Industrial waste gas refers to the general term for various pollutant gases discharged into the air during fuel combustion and production processes within the factory area of ​​an enterprise. To avoid air pollution, the waste gas needs to be filtered. Electrostatic dust collection is a common method for filtering waste gas. It usually uses high voltage electricity to discharge through electrode rods, causing the waste gas particles in the hollow dust collecting pipe to generate corona repulsion and gather and adhere to the pipe wall.

[0003] Most of the current high-voltage electrostatic dust collection filter devices have too simple a structure and cannot effectively clean the dust collecting pipe wall regularly. If the dust collecting pipe is used for a long time, it is easy for the pipe wall to absorb too many exhaust gas particles, affecting the subsequent dust collection effect. At the same time, the dust collecting pipe needs to be disassembled to clean its interior, which is very inconvenient. Utility Model Content

[0028] In this embodiment, a collecting groove 41 is provided at the top of the collecting pipe 4 to facilitate the collection of fallen exhaust gas particles. Limiting blocks 9 are fixedly installed on the two edge ends away from the top of the collecting pipe 4. Movable grooves 91 are provided at the tops of the two limiting blocks 9. Reset grooves 92 are provided at the two ends away from each other. Springs 93 are fixedly connected in the two reset grooves 92.
