The invention relates to an arrangement and method for purification of flowing gas. The invention comprises at least one flow duct (1, 5, 6, 7), with a first potential, which has an internal dimension and through which the gas is arranged to flow, and at least one electrode (2) with a secondary potential, arranged parallel to the flow duct (1, 5, 6, 7), to which ion-producing tips (3) are attached, which, by means of the voltage connected to them, can ionize the gas arranged to flow in the flow duct (1, 5, 6, 7). Electrode (2) is closed member in relation to the flow duct (1, 5, 6, 7), which has a volume and through which the gas cannot flow, so that the gas in the flow duct (1, 5, 6, 7) has a flow with a ring-shaped flow cross-sectional surface. |
