<p>A device for entraining a liquid (10) into a carrier gas (61) comprises a hollow cylindrical body (30) having an inlet chamber (11) separated from the interior (54) of the body by a partition (13). A first nozzle (66) and second nozzle (64) are each supported in the partition (13) and interconnect the inlet chamber (11) and the body interior (54). A passageway (42) connects a reservoir (15) to the first nozzle (66) so that a first stream of carrier gas (67) flowing through the first nozzle (66) aspirates a liquid within the reservoir and entrains the liquid therein. A second stream of carrier gas (67) flows through the second nozzle (64) and mixes with the first stream in the interior (54) of the body, thereby forming a resultant carrier gas mixture (21) that is lower in liquid concentration than obtainable by having the first nozzle alone. An air inlet opening (62) with an adjustable cover (52) communicates between the interior (54) of the body and its exterior. The air inlet opening (62) is located adjacent the discharge ends of the nozzles to draw air into the resultant carrier gas mixture to dilute the concentration of carrier gas. The cylindrical body (30) is V-shaped, the reservoir (15) being a separable container that attaches thereto and, when empty, may be detached and replaced with a new reservoir. A drain opening (46) is formed in the cylindrical body (30) at its lowest point and aligns with a vent (120) opening of the container (15) when the container is fully engaged with the cylindrical body (30), thereby maintaining a constant pressure over the liquid in the container and allowing condensed liquid to drain back into the container.</p> |
