| 摘要 |
The invention relates to a method for purifying a gas in an exhaust gas system comprising an exhaust duct comprising a filter for filtering fine particles, said method comprising spraying of water mist into said exhaust duct upstream of said filter for purifying said gas, said spraying being effected by at least one spray nozzle causing a negative pressure for sucking the gas into the sprayed spray and by guiding said mixture aside from said filter and guiding thus purified gas into the filter. Due to the method gases can be continuously purified without the filter of the exhaust gas system being clogged. When applied to a room having a fire the method simultaneously enables purification of flue gases, sucking of heat out from the room and enables small particles to be captured by the filter. The present invention also relates to an exhaust gas system.
