Description

Technical Field

[0001] The present application relates to the field of dust collectors, and in particular to a wet electrostatic dust collector for treating flue gas from a graphitization furnace. Background Art

[0002] A wet electrostatic precipitator (ESP) is a type of dust removal device that uses electrostatic force (Coulomb force) to separate particles from the airflow. Its main operating principle is to spray water mist onto the discharge electrode and corona zone. The water mist becomes charged within the powerful corona field, splitting and further atomizing. The electric field force, combined with the collision, interception, adsorption, and agglomeration of the charged water mist, collectively capture dust particles. Ultimately, driven by the electric field, the dust particles reach the collecting electrode and are captured. A continuous water film forms on the collecting electrode, flushing the captured dust into the hopper and discharging it with the water.

[0003] However, after a traditional wet electrostatic precipitator has been cleaning dust for a long time, too much dust will accumulate on the dust collecting electrode, thus affecting the subsequent cleaning quality. Summary of the Invention
