A device for purification of gases mixed with dust, for example car exhaust fumes, flue gases and other gases containing electrically conductive or actuatable dust particles, said device comprising a flow channel extending from an inlet for the gases to be purified to an outlet for the purified gases, within which channel an electric high voltage field is arranged between electrodes of opposite polarity. In order to obtain an improved efficiency the flow channel (26) is provided with ionization means (41) arranged consecutively in the direction of flow, having the same or opposite polarity and disposed before each their electric high voltage field (27, 31; 27, 31) as seen in the direction of flow of the gas through the flow channel. |
