Abstract | This invention provides a fine bubble generating apparatus which can efficiently generate fine bubbles on the nanometer level. This apparatus comprises a cylindrical member (40) having a cylindrical inner peripheral surface, a first end wall member (42) configured to close one end of the cylindrical member, and a second end wall member (44) configured to close the other end of the cylindrical member. The cylindrical member (40) and the first and second end wall members (42) and (44) define a fluid swirling chamber (46). The cylindrical member has a fluid inlet hole (48) at a position close to the second end wall member (44) to supply a gas-liquid mixed fluid in the tangential direction of the peripheral surface of the fluid swirling chamber (46). The second end wall member has a fluid outlet hole (50) extending therethrough along the center axis of the inner peripheral surface of the fluid swirling chamber. The gas-liquid mixed fluid is introduced into the fluid swirling chamber at a position close to the second end wall member. Most of the fluid is directed toward the first end wall member while swirling along the inner peripheral surface of the fluid swirling chamber, reversed from the first end wall member toward the second end wall member and discharged through the fluid outlet hole. Selected Figure; Fig.2
L'appareil objet de cette invention peut générer efficacement de fines bulles au niveau nano. L'appareil comprend un membre cylindrique (40) qui a une face périphérique interne cylindrique, une première paroi d'extrémité (42) positionnée de manière à boucher une extrémité du membre cylindrique et une seconde paroi d'extrémité (44) positionnée de manière à boucher l'autre extrémité du membre cylindrique. Membre cylindrique (40), première paroi d'extrémité (42) et seconde paroi cylindrique (44) forment une chambre tourbillonnaire fluide (46). Un orifice d'insertion de fluide (48) qui alimente un liquide constitué de gaz et de liquide tangentiellement à la fâce périphérique de la chambre tourbillonnaire fluide (46) est fourni en position fermée sur la seconde paroi d'extrémité (44) dans le membre cylindrique. Un orifice d'expulsion de fluide (50) qui passe à travers une ligne axiale centrale de la fâce périphérique interne de la chambre tourbillonnaire fluide est ensuite fixé à la seconde paroi d'extrémité. Le mélange gaz-liquide rentre dans la chambre tourbillonnaire fluide avec la seconde paroi d'extrémité en position fermée et la majeure partie du fluide est orientée vers la première paroi d'extrémité tout en tourbillonnant le long de la chambre tourbillonnaire avant d'être dirigée vers la seconde paroi d'extrémité à travers un orifice d'expulsion. |
