Abstract

L'invention concerne un générateur de liquide à microbulles avec lequel il est possible d'empêcher une réduction de la pression de l'eau fournie et d'assurer une quantité suffisante d'eau tout en garantissant la concentration de microbulles nécessaire. Un tuyau d'eau (2) relié à une tuyauterie d'alimentation en eau de robinet (12) comporte, dans une partie de celui-ci, une partie élargie (4) dont le diamètre est agrandi. La partie élargie (4) est pourvue d'un élément de support (6) comprenant une partie de bague interne (6a) pour maintenir une buse (5) sur sa périphérie interne, une partie de bague externe (6b) fixée à la partie étendue (4), et une pluralité de parties de rayons (6c) pour relier la partie de bague interne (6a) et la partie de bague externe (6b). La buse (5) comprend, sur une plaque d'admission d'eau côté entrée (7), une pluralité de trous d'admission d'eau (8) dont les axes centraux sont inclinés par rapport à l'axe du tuyau d'eau (2) d'une alimentation en eau de robinet. L'eau de robinet évacuée diagonalement à partir de chacun des trous d'admission d'eau (8) augmente en vitesse tout en tourbillonnant en forme de spirale sur la paroi interne d'un premier canal d'eau (8a) et est éjectée dans un second canal d'eau (8b). La diminution rapide résultante de la pression génère un liquide à microbulles contenant un très grand nombre de bulles de cavitation ultrafines. Le liquide à microbulles est fusionné avec de l'eau de robinet qui passe entre les parties de rayons (6c) s'ouvrant dans l'élément de support (6) sans traverser la buse (5), et est évacuée en aval.
