Abstract: An exhaust purification system for purifying exhaust gas from a combustion engine comprising: an exhaust pipe (10) for the supply of exhaust gas; a pre-chamber (12) for receiving a flow of exhaust gas via a supply pipe (14); a supply valve (16) for controlling a flow of exhaust gas into the pre-chamber; at least one mixing chamber (18), in fluid connection with the pre-chamber for receiving the exhaust gas via the pre-chamber; an ionizing equipment (20) configured to ionize air, connected to the mixing chamber (18) so that ionized air is fed into the mixing chamber and is mixed with the exhaust gas; wherein the supply valve (16) is configured to be controlled based on a flow velocity of exhaust gas in the exhaust pipe (10).

Abstract: A purification arrangement for purifying a contaminated gaseous medium comprising: an ionizing equipment for ionizing air; a supply pipe for the supply of contaminated air; and at least one mixing chamber, wherein the contaminated air is fed through the mixing chamber in a main flow and ionized air is added to the main flow; an inlet for introducing ambient air into the main flow of the contaminated gaseous medium prior to the mixing chamber; a first temperature sensor arranged in the supply pipe prior to the inlet and configured to detect the temperature of the contaminated gaseous medium; wherein if the temperature of the contaminated gaseous medium detected by the first temperature sensor is above 70° C., ambient air is added through the inlet into the main flow.
