Facility for producing and treating a gas stream through a volume of liquid

A facility (1A;

• 1B;
• 1C;
• 1D;
• 1E) for producing and treating a gas stream, said facility including at least two treatment devices (2) each including an exchange enclosure (20) containing a liquid bath in its bottom, wherein each exchange enclosure includes at least one opening (20f) for discharging a gas stream, wherein each treatment device (2) includes at least one injection conduit (21) having at least one intake opening (21a) and at least one discharge opening (21b), said facility further including aeraulic means (4), which are connected to all the discharge openings (20f) of the exchange enclosures (20) or which are connected to all the intake openings (21a) of the injection conduits (21), and which, during operation, make it possible to create, by suction or blowing, simultaneously and in parallel for each treatment device (2), an incoming gas stream (F) coming from the outside of the exchange enclosures (2), wherein each injection conduit (21) of the corresponding treatment device (2) is designed to introduce each corresponding incoming gas stream (F) and to allow said stream to pass through the discharge opening (21b) of the injection conduit (21), said discharge opening (21b) of the injection conduit (21) being designed to introduce said stream into the liquid bath contained in the bottom of the exchange enclosure (20), below the surface (S) of said liquid bath, and the exchange enclosure is designed to allow an outgoing gas stream (F′), treated by direct contact with said liquid bath, to rise up inside the exchange enclosure, and to discharge said outgoing gas stream out of said exchange enclosure (20) by allowing it to pass through the discharge opening (20f) of the exchange enclosure (20), wherein the exchange enclosures (20) communicate hydraulically with one another so that, when the aeraulic means (4) are not operating each exchange enclosure (20) contains, at its bottom, an initial volume (Vinitial) of liquid, with an initial level (Hinitial) of liquid which is identical in all the exchange enclosures (2).
