Preferably, each adsorption plate includes a plurality of ventilation holes, the plurality of ventilation holes are arranged in at least one row along the axial direction, wherein the hole center of any ventilation hole on one adsorption plate on the adjacent two adsorption plates is arranged on a different plane perpendicular to the axial direction from the hole center of any ventilation hole on the other adsorption plate.

Because the hole centers of the second vent hole 1520 and the third vent hole 1530 are arranged on different planes perpendicular to the axial direction of the third chamber 1130, the gas flow direction of the gas passing through the third chamber 1130 is disturbed, further increasing the residence time of the gas in the two chambers, being beneficial to increasing the frequency of contact with the discharge electrode at a close distance, the closer to the discharge electrode, the higher the gas ionization efficiency, and improving the particulate matter charging efficiency and the charging amount; and when the gas forms a cyclone flow direction, the separation of large particles is facilitated, the two points are combined, and the dust removal efficiency is effectively improved. In this embodiment, since the adsorption plates of each chamber can be provided with the vent holes, the vent holes on the different adsorption plates of the same chamber are arranged on different planes perpendicular to the axial direction of the chamber, so that the gas of each chamber can originate from a plurality of adjacent chambers and can flow to a plurality of adjacent chambers, the gas flow direction is highly turbulent, the gas flow passing near the discharge electrode is increased, the particulate matter charging efficiency and the charging quantity in the gas are increased, and the dust removal efficiency is improved.
