Description

Kegelschleuder mit Venturi-Einlaufsystem zur intensiven Vermischung zweier Phasen (flüssig-gasförmig)Cone centrifuge with Venturi inlet system for intensive mixing of two phases (liquid-gaseous)

Stand der Technik:State of the art:

Bekanntlich läßt sich mit Hilfe des Venturi-Effektes bei schnell stromerndem Treibmittel (Flüssigkeit) und entsprechend abgestimmter Düsenöffnung ein Unterdruck erzeugen und z.B. Gas (Luft) ansaugen. Der Flüssigkeitsdruck und die Düsenöffnung bestimmen die dabei mitgerissene Luftmenge. Die Vermischung beider Phasen ist nur unzureichend. It is well known that with the help of the Venturi effect, a low pressure can be generated with a rapidly flowing propellant (liquid) and a correspondingly adjusted nozzle opening, and gas (air) can be sucked in, for example. The liquid pressure and the nozzle opening determine the amount of air entrained . The mixing of the two phases is inadequate.

Bei vielen Applikationen ist es aber wünschenswert, eine möglichst intensive Vermischung von Flüssigkeit und Gas zu bewerkstelligen und diesen Zustand möglichst lange stabil zu halten.However, in many applications it is desirable to achieve the most intensive mixing of liquid and gas possible and to keep this state stable for as long as possible.

Der Erfindung liegt der Lösungsansatz zugrunde, mit einem nachgeschaltetem Rotationskörper beide Phasen in hohe Rotation zu versetzen. Dabei wird der Partialdruck in der Drehachse gesenkt. Das Lösungsvermögen von Gas in der Flüssikeit wird erhöht und durch intensive Verwirbelung relativ lange stabil gehalten.
Dies ist zum Beispiel bei Belüftungsvorgängen von entscheidender Bedeutung.The invention is based on the solution approach of setting both phases into high rotation using a downstream rotating body . This reduces the partial pressure in the axis of rotation. The dissolving capacity of gas in the liquid is increased and kept stable for a relatively long time by intensive turbulence.
This is crucial, for example, in ventilation processes .

Vorteile:Advantages:

* Intensive Vermischung von beiden Phasen* Intensive mixing of both phases

* Bessere Anreicherung* Better enrichment

* Längerer stabiler Zustand* Longer stable state

* Gleichzeitige Separatation spez. schwererer Anteile mit Hilfe der Zentrifugalkraft* Simultaneous separation of heavier particles using centrifugal force
