Abstract
La présente invention est relative à un procédé et un dispositif pour introduire des bulles gazeuses dans un liquide. Dans le procédé de l'invention, on forme une émulsion dont la fraction de vide est importante, on l'envoie dans le récipient et on dévie le jet complexe formé par l'émulsion et le liquide entraîné de façon à lui imposer un trajet incurvé. Les gradients de pression provoqués par la courbure du trajet provoquent une migration des bulles de l'émission et les diluent dans la masse du liquide, où elles prennent un mouvement ascentionnel. Application à la flottation, en particulier d'eaux contenant des flocs peu stables.
