Title
(EN) DEVICE AND METHOD FOR MIXING TWO FLUIDS
(FR) DISPOSITIF ET PROCÉDÉ DE MÉLANGE DE DEUX FLUIDES
Abstract
(EN)
A mixing device (10) for mixing a first fluid and a second fluid comprises a housing (12) which is provided with a first inlet (20) for the first fluid, a second inlet (27) for the second fluid, a mixing chamber (42) for mixing the first fluid and the second fluid into a mixture of the first fluid and the second fluid, and an outlet (26) for the mixture of the first fluid and the second fluid. The housing (12) is provided with a plurality of heat exchanger tubes (36) having tube walls (37) which are situated next to each other and extend substantially parallel to each other. The interiors of the tube walls (37) define elongate first channels (38). Each elongate first channel (38) comprises a first supply opening (65) and a first discharge opening (66,81). The first supply openings (65) are in fluid communication with the first inlet (20) for the first fluid. At least a number of the first discharge openings (66,81) are in fluid communication with the mixing chamber (42). The tube walls (37) of adjacent heat exchanger tubes (36) are connected to each other so as to define elongate second channels (58) on the exterior of the tube walls (37). Each elongate second channel (58) comprises a second supply opening (75) and a second discharge opening (76). The elongate second channels (58) are in fluid communication with the second inlet (27) for the second fluid and with the mixing chamber (42) by means of the second openings (75,76).

La présente invention concerne un dispositif (10) de mélange permettant de mélanger un premier fluide et un second fluide et comprenant un boîtier (12) pourvu d'un premier orifice d'entrée (20) destiné au premier fluide, d'un second orifice d'entrée (27) destiné au second fluide, d'une enceinte de mélange (42) pour le mélange du premier fluide et du second fluide en vue de l'obtention d'un mélange associant le premier fluide et le second fluide, et d'un orifice de sortie (26) du mélange associant le premier fluide et le second fluide. Le boîtier (12) est pourvu d'une pluralité de tubes échangeurs de chaleur (36) dont les parois (37) sont situées à proximité les unes des autres et sont quasiment parallèles les unes aux autres. L'intérieur des parois des tubes (37) définissent des premiers canaux allongés (38). Chaque premier canal allongé (38) comprend une première ouverture d'alimentation (65) et une première ouverture d'évacuation (66, 81). Les premières ouvertures d'alimentation (65) sont en communication fluidique avec le premier orifice d'entrée (20) destiné au premier fluide. Au moins certaines des premières ouvertures d'évacuation (66, 81) sont en communication fluidique avec l'enceinte de mélange (42). Les parois des tubes échangeurs de chaleur adjacents (36) sont reliées les unes aux autres de façon à définir des seconds canaux allongés (58) à l'extérieur des parois des tubes (37). Chaque second canal allongé (58) comprend une seconde ouverture d'alimentation (75) et une seconde ouverture d'évacuation (76). Les seconds canaux allongés (58) sont en communication fluidique avec le second orifice d'entrée (27) destiné au second fluide et avec l'enceinte de mélange (42) par le biais des secondes ouvertures (75, 76).
