KOERFARANDE OCH ANLAEGGNING FOER BEHANDLING AV LUFT I OMRAADET AV EN TRAFIKLED FOER MOTORFORDON

摘要

An installation for air treatment in the area of a traffic route for motor vehicles (30) emitting air-polluting exhaust gases comprises an elongate shell (1) which completely or partly encapsulates the traffic route and in which outlets (19) are arranged for evacuating the air present in the shell and polluted by the exhaust gases from the vehicles passing through the shell. The outlets (19) communicate with filters (22) positioned in air treatment stations (11) spaced from each other in the longitudinal direction of the shell, for cleaning the exhaust air before it is discharged into the atmosphere.
