Description
Propeller 7 und 8 sehr fein zerschlagen und unter Überwindung des Gegendrucks der Wassersäule durch die er- ; zeugte Strömung in die Flüssigkeit mitgerissen und durch j starke Turbulenz innig mit der Flüssigkeit vermischt, ? so daß der Lufteintrag im wesentlichen außerordentlich ■ feinblasig (ca. 1 min Durchmesser der Luftblasen) unc
dair.it für die Begasung der Flüssigkeit f.-u^erc^centlic·:. | effektiv erfolgt und eine hohe "Rate ar, Lccur.^: vor. 0~s j in der Flüssigkeit erzeugt wird. !
Vorrichtung in dem Gas- bzw. Liutsuführungskänal 9 unc;
dem Belüftergehäuse 3 stehende Flüssigkeit zu verdrängen,
so daß, wie bereits gesagt, der Ventilator 10 ein Kiederdruckventilator sein kann. Wenn der Ventilator 10, wie
oben beispielhaft angegeben, bei einer Leistungsaufnahme.
Flüssigkeiten mit Feststoffen eine Strömung bzw. Umwälzung erzeugt v/erden soll oder wo gasförmige Medien wie luft, Sauerstoff, andere Gase oder deren Gemische möglichst feinblasig in flüssige Medien (oder Mischungen von Flüssigkeiten mit Feststoffen) eingebracht werden sollen, insbesondere auch sur Herbeiführung cherischer "Reaktionen.
