The gas is ionized to generate a large amount of free electrons and positive ions, the free electrons are attached to gas molecules to form negative ions, and when the dust-containing gas passes through an electric field, the negative ions collide with dust particles to realize the charge of the dust. Under the action of the electric field force, the charged dust moves to the dust collecting electrode and is collected by the dust collecting electrode. Meanwhile, positive ions in the corona area move to the adjacent corona electrode and collide with dust particles to charge the dust particles positively, and the dust particles charged positively are attached to the corona electrode under the action of an electric field force.
