Abstract

La présente invention concerne un générateur de bulles générant des microbulles dont la taille est de l’ordre du nanomètre (1/1 000 000 mm ; 10-9) en faisant tourner une section rotative à une vitesse supérieure à et indépendamment de la vitesse d’une source d’entraînement rotatif. Des aimants (10, 11) et (13, 14) dotés de polarités différentes sont disposés entre une roue à aubes de pompe (17), un élément de retenue (12) tourné par un moteur immergé (8) et les deux extrémités d’une section rotative (4). Des aimants de répulsion fixes (15) sont disposés, à un pas prédéterminé dans la direction axiale d’un tube externe (3), sur une surface circonférentielle interne du tube externe (3) qui fait face à la surface circonférentielle externe de la section rotative (4). Des aimants de répulsion rotatifs (16) sont disposés, à un pas prédéterminé dans la direction axiale de la section rotative (4), sur la surface circonférentielle externe de la section rotative (4) qui fait face à la surface circonférentielle interne du tube externe (3). Les aimants de répulsion fixes (15) et les aimants de répulsion rotatifs (16) se composent d’aimants ayant la même polarité, ce qui leur permet de s’appliquer réciproquement une répulsion par l’intermédiaire d’une force magnétique. La force augmentant la vitesse de rotation par répulsion apparaissant à partir du moment où l’aimant de répulsion fixe (15) et l’aimant de répulsion rotatif (16) se font face jusqu’au moment où ils se séparent est supérieure à la force de restriction de rotation par répulsion apparaissant à partir du moment où ils sont proches les uns des autres jusqu’au moment où ils se font face.
