Die als nächstliegend angesehene Druckschrift
Die Aufgabe der Erfindung besteht somit darin, eine Vorrichtung zum Dispergieren, Mikronisieren usw. der dispersen Phase zur Verfügung zu stellen, mit welcher eine Stabilisierung der erzeugten Tropfen, Partikel usw. erreicht werden kann.The object of the invention is therefore to provide a device for dispersing, micronizing, etc. of the disperse phase available, with which a stabilization of the generated droplets, particles, etc. can be achieved.
Diese Aufgabe wird insbesondere durch eine Vorrichtung erreicht, wie sie im Anspruch 1 angegeben ist, wobei der Innenraum, in Verbindung mit den Eintrittsdüsen und Austrittsdüsen, derart ausgebildet ist, dass in ihm eine Strömungsform auftritt, durch welche die gewünschte effiziente Stabilisierung der erzeugten Tropfen, Partikel usw. erreicht werden kann. Weiterhin ist der Durchflussquerschnitt der Austrittsdüsen größer als der Durchflussquerschnitt der Eintrittsdüsen. Insbesondere kann durch die erfindungsgemäße Ausgestaltung einer Vorrichtung zum Dispergieren, Mikronisieren usw. eine gute Stabilisierung des Produkts erreicht werden.This object is achieved in particular by a device as set forth in claim 1, wherein the interior space, in conjunction with the inlet nozzles and outlet nozzles, is designed in such a way that a flow form occurs therein through which the desired efficient stabilization of the drops produced, Particles, etc. can be achieved. Furthermore, the flow area of the outlet nozzles is greater than the flow area of the inlet nozzles. In particular, a good stabilization of the product can be achieved by the inventive design of a device for dispersing, micronizing, etc.

Die Eintrittsdüse und die Austrittsdüse weisen vorzugsweise einen kreisförmigen, rechteckigen oder elliptischen Querschnitt auf.The inlet nozzle and the outlet nozzle preferably have a circular, rectangular or elliptical cross section.
Die Eintrittsdüse weist bevorzugt einen Durchmesser bzw. eine Schlitzweite im Bereich von etwa 0,1 bis 5 mm und insbesondere im Bereich von etwa 0,2 bis 0,6 mm auf.The inlet nozzle preferably has a diameter or a slot width in the range of about 0.1 to 5 mm and in particular in the range of about 0.2 to 0.6 mm.
Die Austrittsdüse weist bevorzugt einen Durchmesser bzw. eine Schlitzweite im Bereich von etwa 0,1 bis 10,0 mm und insbesondere im Bereich von etwa 0,2 bis 2,0 mm auf.The outlet nozzle preferably has a diameter or a slot width in the range of about 0.1 to 10.0 mm and in particular in the range of about 0.2 to 2.0 mm.
Sowohl die Eintrittsdüsen als auch die Austrittsdüsen sind vorteilhafterweise jeweils in einem Winkel im Bereich von etwa 10° bis 350° relativ zueinander angeordnet, wobei ein Idealfall im Bereich von etwa 45° bis 315° geeignet ist, und ein Winkel α von im Wesentlichen 180° bevorzugt wird.Both the inlet nozzles and the outlet nozzles are advantageously each arranged at an angle in the range of about 10 ° to 350 ° relative to each other, an ideal case in the range of about 45 ° to 315 ° is suitable, and an angle α of substantially 180 ° is preferred.
Jede der Eintrittsdüsen und der Austrittsdüsen ist zweckmäßigerweise mit einem Düsenhalter versehen, in welchem die eigentliche Düse aufgenommen ist.Each of the inlet nozzles and the outlet nozzles is expediently provided with a nozzle holder, in which the actual nozzle is accommodated.
Der Düsenhalter ist vorzugsweise mit einem konischen Zulauf und/oder einem konischen Auslauf ausgestattet.The nozzle holder is preferably equipped with a conical inlet and / or a conical outlet.
Nach einer Weiterbildung können die Eintrittsdüsen eines Düsenpaars parallel versetzt zueinander angeordnet sein.According to a development, the inlet nozzles of a nozzle pair can be arranged offset parallel to one another.

Die konische Ausbildung von Zulauf 32 und Ablauf 34 führt zu einer Reduzierung des Strömungsverlustes im Zu- und Auslauf der Düsen. Außerdem bewirkt der konische Auslaß bei den Eintrittsdüsen 14 eine Zwangsaufweitung des Fluidstrahles, die sich positiv auf die Turbulenzentwicklung im Düsenkörper 12 auswirkt.The conical design of
Die Düse 30 kann im Querschnitt kreisförmig, schlitzförmig oder rechteckig ausgebildet sein, wobei der Durchmesser bzw. die Schlitzweite bei der Eintrittsdüse 14/30 im Bereich von etwa 0,1 bis 5 mm, und vorzugsweise im Bereich von 0,2 bis 0,6 mm liegt. Bei schlitzförmigen oder rechteckigen Düsen beziehen sich diese Maßangaben auf den kleineren Wert, d.h. auf die Schlitzweite oder Schlitzhöhe. Die Länge der schlitzförmigen oder rechteckigen Düse 30 kann im Bereich von 1 bis etwa 50 mm liegen.The
Bei der Austrittsdüse 30/16 liegt der Durchmesser bzw. die Schlitzweite im Bereich von etwa 0,1 bis 10,0 mm, und vorzugsweise im Bereich von etwa 0,2 bis 2 mm. Auch hier beziehen sich diese Maßangaben bei der schlitzförmigen oder rechteckigen Düse auf den kleineren Wert, d.h. auf die Schlitzweite oder Schlitzhöhe.

Der Durchmesser bzw. die Schlitzweite oder allgemein der Düsenquerschnitt ist bei der Austrittsdüse 30/16 stets größer als bei der Eintrittsdüse 30/14. Hierbei wird der Durchmesser bzw. die Schlitzweite der Austrittsdüse 30/16 so gewählt, dass etwa 1 bis unter 50 % des Gesamtdruckabfalles über den Austritt des Mediums aus der Dispergiervorrichtung erfolgt.The diameter or the slot width or generally the nozzle cross section is always larger at the

Auch der entsprechende Winkel zwischen den Mittelachsen der beiden Austrittsdüsen 16 kann in einem Bereich von etwa 10° bis 350°, zweckmäßigerweise in einem Bereich von etwa 45° bis 315° liegen, und er beträgt vorzugsweise 180°.Also, the corresponding angle between the center axes of the two
In der bevorzugten Ausführungsform, also bei einem Winkel α = 180° zwischen den beiden Eintrittsdüsen 14 treffen die eintretenden Fluidstrahlen direkt aufeinander. Dies hat zur Folge, dass der Impuls der Strahlen sich sehr schnell aufhebt, wobei der Zeitraum für die Aufhebung des Impulses der aufeinander treffenden Fluidstrahlen in erster Linie von der Strömungsgeschwindigkeit abhängig ist. Diese wiederum steht in engem Zusammenhang mit dem Druckabfall und den Stoffeigenschaften der zu behandelnden Substanzen. Wie oben bereits erwähnt, werden die Abmessungen der Düsen 30 so gewählt, dass weniger als 50% des Gesamtdruckabfalles in den Austrittsdüsen erfolgt. Dadurch kann das Maß und der Ort von Kavitationserscheinungen kontrolliert werden. Der Gesamtdruckabfall über das Düsensystem liegt über 10 bar und vorzugsweise über 100 bar.In the preferred embodiment, ie at an angle α = 180 ° between the two

Der oben beschriebene Druckabfall über der Austrittsdüse und die daraus resultierende Strömungsgeschwindigkeit, die mit turbulenten Schwankungsbewegungen behaftet ist, sorgen in erster Linie dafür, dass neu gebildete Grenzflächen von Emulgierhilfsmitteln benetzt werden können, und führt somit zu einer Stabilisierung des Produktes.The above-described pressure drop across the discharge nozzle and the resulting flow velocity, which is subject to turbulent fluctuation movements, provide primarily for the fact that newly formed interfaces can be wetted by emulsifying aids, and thus leads to a stabilization of the product.
Die in der erfindungsgemäßen Vorrichtung zu behandelnden Stoffe sind vorzugsweise Emulsionen aus mindestens zwei ineinander nahezu unlöslichen Flüssigkeiten, Schäume mit mindestens einer gasförmigen und mindestens einer flüssigen Komponente sowie Suspensionen, bei denen mindestens eine Feststoffkomponente in einem fluiden System formuliert wird.The substances to be treated in the device according to the invention are preferably emulsions of at least two liquids which are almost insoluble in one another, foams having at least one gaseous and at least one liquid component and suspensions in which at least one solid component is formulated in a fluid system.
