Abstract

La présente invention concerne un générateur de microbulles comprenant : une première section Venturi (110) ; une seconde section Venturi (130) ; et une section de mélange (120) pour accoupler un écoulement de fluide entre la première section Venturi et la seconde section Venturi, la première section Venturi (110) présentant une première section convergente (112) accouplée à une première section divergente (116), créant un premier étranglement pour un écoulement de liquide à travers le générateur de microbulles, et ayant un orifice d'entrée de gaz (118) au niveau ou à proximité de la partie la plus étroite de l'étranglement pour aspirer du gaz dans un liquide s'écoulant à travers le premier étranglement, la seconde section Venturi (130) présente une seconde section convergente (132) accouplée à une seconde section divergente (136), et créant un second étranglement pour un écoulement de liquide à travers le générateur de microbulles, et la section de mélange (120) s'accouplant entre la première section divergente (116) et la seconde section convergente (132).
