Device for producing and treating a gas stream through an automatically controlled volume of liquid

An apparatus for producing and treating a gas stream (F), the apparatus comprising an exchange enclosure (2) having at least one first discharge opening (2b) for discharging a gas stream, a liquid supply conduit (40) for supplying the exchange enclosure (2) with a liquid (L) such that the exchange enclosure (2) can contain a volume (V) of this liquid with said first discharge opening (2b) of the exchange enclosure being positioned above the surface (S) of the volume of liquid (V) contained in the exchange enclosure, and a discharge conduit (50) for discharging the liquid (L) contained in the exchange enclosure (2) and an aeraulic device (6), which is capable, during operation, of creating, by suction or blowing, an incoming gas stream (F) coming from the outside of the exchange enclosure (2), such that this incoming gas stream (F) is introduced into the volume of liquid (V) contained in the exchange enclosure (2), below the surface (S) of said volume of liquid, and such that an outgoing gas stream (F′) treated by direct contact with said volume of liquid rises up inside the exchange enclosure and is discharged out of said exchange enclosure (2) by passing through the at least one first discharge opening (2b) of the exchange enclosure (2), wherein said apparatus further comprises a measuring device (7) for measuring a first operating parameter (Xout) measured in the outgoing gas stream (F′) and said apparatus comprises an electronic control unit for automatically controlling a liquid supply into the exchange enclosure through the supply conduit (40) and for automatically controlling a liquid discharge out of the exchange enclosure through the discharge conduit (50) so as to automatically adjust the height (h) of liquid in the exchange enclosure depending on at least this first operating parameter (Xout).
