Abstract
Dispositif de distribution d'un gaz dans un milieu liquide. Dans ce dispositif pour introduire un gaz dans un milieu liquide, comprenant un rotor, ou roue 9, pourvu d'ailettes et un stator également pourvu d'ailettes 11, la roue étant pourvue de moyens pour l'introduction d'un gaz, tel que de l'air, vers un vide prévu au centre du rotor, à partir duquel des conduites sont prévues pour l'épuisement de l'air dans le milieu liquide, ces conduites se terminent entre deux ailettes adjacentes et sont prévues dans le bossage du rotor au voisinage de la face arrière d'une ailette, l'axe de chaque conduite interceptant un rayon à travers l'ailette sur la face arrière de laquelle la conduite se termine. La présente invention est particulièrement utile pour fournir une introduction et une dispersion d'un gaz dans un milieu liquide.
