  • Bubbles that can contribute to water purification are considered to be 2-3 micron diameters or smaller. Therefore, the existence of such bubbles cannot be confirmed by hand.

Abstract

L'invention concerne un dispositif de purification de la qualité de l'eau permettant de générer des bulles extrêmement fines et de dissoudre des composants oxygénés dans de l'eau d'admission provenant d'une zone d'eau faisant l'objet d'une purification, puis de les introduire en continu dans la zone d'eau faisant l'objet de la purification. Le dispositif comprend un tuyau d'admission (1), un cylindre d'enveloppe extérieur (3), un cylindre d'enveloppe intérieur (4), une plaque de guidage d'eau (5), une plaque de pulvérisation d'eau (6) équipée d'un aimant rotatif, une tige rotative (7) et un moteur immergé (8). Le flux tourbillonnaire généré entre le cylindre d'enveloppe intérieur rotatif (4) et le cylindre d'enveloppe extérieur (3) mélange l'air avec l'eau pour former de nombreuses bulles très fines et dissout les composants oxygénés dans les bulles se trouvant dans l'eau d'admission. Les bulles très fines provenant du dessus sont d'avantage divisées et transformées en bulles plus fines par l'effet de synergie entre l'opération de pompage et une opération électromagnétique entre la plaque de pulvérisation d'eau et la plaque de guidage d'eau (5), les composants oxygénés dans ces bulles étant d'avantage dissous dans l'eau.
