Patent ID: 7892336

Claim:
Apparatus for extracting gaseous, liquid and/or solid elements from a gaseous medium and concentrating said elements in a liquid medium, by nebulizing the liquid medium by means of the gaseous medium for producing a mist and condensing the droplets of liquid medium forming the mist produced by the nebulization, said apparatus comprising: a first enclosure for nebulization and condensation, which has an upper part and a lower part intended to contain the liquid medium, which is provided with a conduit for delivering the gaseous medium into the first enclosure and means for nebulizing the liquid medium, and which is connected to a conduit for discharging the gaseous medium from the first enclosure; means for depressurizing or pressurizing the interior of the first enclosure to allow the gaseous medium to enter the first enclosure, circulate therein and be discharged therefrom, in a continuous flow; at least one second enclosure for condensation, this second enclosure being connected to the conduit for discharging the gaseous medium from the first enclosure, and being provided with a conduit for discharging the gaseous medium from the second enclosure; means for cooling the second enclosure, wherein the conduit for delivering the gaseous medium into the first enclosure has a first end located outside the first enclosure and a second end housed in the first enclosure; wherein the means for nebulizing comprises: a nebulization nozzle which is located level with the second end of the conduit and which has at least one orifice; and a nebulization tube provided with a first opening which is located in a lower part of the first opening which is located in a lower part of the first enclosure, and a second opening which is flush with the orifice of the nebulization nozzle; and wherein a connection between the first enclosure and the conduit for discharging the gaseous medium from the first enclosure is located substantially at a same height as the nebulization nozzle, or shifted with regard to the orifice of the nebulization nozzle to the direction opposite to the direction in which the gaseous medium is delivered into the first enclosure.
