Forced recirculation mixer

A forced recirculation mixer (1) designed to mix at least one vaporizable liquid (2) with at least one gas (3) to be mixed so as to form a homogeneous gaseous mixture (4) characterized in that it comprises:

• at least one stirring enclosure (5) whose internal cavity forms a recirculation loop (6) in which the homogeneous gaseous mixture (4) can circulate continuously, the beginning and the end of the recirculation loop (6) being combined;
• at least one gas inlet duct (7) which emerges directly or indirectly into the stirring enclosure (5) and through which the gas (3) to be mixed is introduced into the recirculation loop (6) by means (8) for the introduction of gas in a known quantity;
• at least one liquid injection nozzle (9) which emerges directly or indirectly into the stirring enclosure (5) to introduce the vaporizable liquid (2) into the recirculation loop (6), said nozzle (9) being fed by means (10) for introducing liquid in a controlled quantity, the vaporizable liquid (2) flow rate of which is controlled by a computer (45), said vaporizable liquid (2) forming, with the gas (3) to be mixed, the homogeneous gas mixture (4);
• at least one mixture draw-off duct (11) which emerges directly or indirectly into the stirring enclosure (5) and through which the homogeneous gas mixture (4) can be drawn-off from the recirculation loop (6) by gas drawing-off means (12);
• and
• at least one stirring turbine (13) which is set in motion by a turbine motor (28) and which is positioned in the recirculation loop (6), said turbine (13) forcing the homogeneous gas mixture (4) to circulate in said loop (6).
