Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Dispergierung von nicht mischbaren Flüssigkeiten oder Gasen und Flüssigkeiten.The invention relates to a method and a device for dispersing immiscible liquids or gases and liquids.

In verschiedensten Anwendungen müssen unmischbare oder schwer mischbare Flüssigkeiten dispergiert werden oder Gase in Flüssigkeiten dispergiert werden. Statische Mischer mit statischen Mischelementen, die gemäss DE 22 05 371 oder gemäss CH 642 564 ausgestaltet sind, eignen sich bekannter Weise sehr gut für diesen Verfahrensschritt.In a wide variety of applications, immiscible or difficult to mix liquids must be dispersed or gases dispersed in liquids. Static mixers with static mixing elements, according to DE 22 05 371 or according to CH 642 564 are configured, well-known way very well for this process step.

Um mittels statischen Mischern eine Dispersion einer vorgegebenen Tropfengrösse zu erzeugen, muss in das fluide Gemisch über Scherung im Mischer über eine gewisse Dispergierstrecke eine gewisse volumetrische Leistung eingetragen werden. Ist die Dispergierstrecke, über die die Scher-oder Dispergierleistung in das fluide Gemisch eingetragen wird, nicht ausreichend lang, sind die entstehenden Tropfen grösser und die entstehende Tropfengrössenverteilung breiter als beim Gleichgewichtszustand für den vorliegenden volumetrischen Leistungseintrag. Ist die Dispergierstrecke länger als bis zur Erreichung des Gleichgewichtszustandes der Tropfenverteilung, ändert sich die Tropfengrössenverteilung nicht mehr gegenüber der Gleichgewichtsverteilung. Unterschiedliche Dispergiersysteme unterscheiden sich nun in der Dispergierstrecke, die nötig ist, bis die Gleichgewichtsverteilung erreicht wird. Je kürzer diese Dispergierstrecke ist, desto weniger Gesamtleistung ist zur Erzeugung der Dispersion erforderlich. Ein statisches Dispergiersystem, das über eine sehr kurze Dispergierstrecke die Gleichgewichtsverteilung der Tropfen in der Dispersion erzeugen kann, hat eine hohe Dispergierleistung, respektive benötigt sehr wenig Leistung zur Erzeugung der Dispersion mit vorgegebener Tropfenverteilung. Somit weist ein statisches Dispergiersystem mit sehr grosser Dispergierleistung typischerweise ein kleines Längen/Durchmesserverhältnis auf.In order to produce a dispersion of a given droplet size by means of static mixers, a certain volumetric power must be introduced into the fluid mixture via shear in the mixer over a certain dispersing distance. If the dispersing path, via which the shear or dispersing power is introduced into the fluid mixture, is not sufficiently long, the resulting droplets are larger and the resulting droplet size distribution wider than in the equilibrium state for the present volumetric input of power. If the dispersing distance is longer than until reaching the equilibrium state of the droplet distribution, the droplet size distribution no longer changes with respect to the equilibrium distribution. Different dispersing systems now differ in the dispersing distance, which is necessary until the equilibrium distribution is reached. The shorter this dispersing distance, the less total power is required to produce the dispersion. A static dispersing system, which can produce the equilibrium distribution of the droplets in the dispersion over a very short dispersion path, has a high dispersing power, respectively, requires very little power for producing the dispersion with predetermined droplet distribution. Thus, points a static dispersing system with very high dispersing power, typically a small length / diameter ratio.

Bisher ist die Dispergierung mit konventionellen statischen Mischern oder mit Rührelementen erfolgt. In beiden Fällen ist normalerweise ein sehr grosser spezifischer Energieeintrag in das fluide Gemisch notwendig, um die gewünschten Tropfengrössen zu erreichen. Bei Prozessen mit statischen Mischern geschieht dieser grosse spezifische Leistungseintrag über eine sehr hohe Produktscherung während der kurzen Zeit, in der sich das fluide Gemisch im statischen Mischer befindet. Diese grosse Scherung führt zu einem grossen Druckverlust über den statischen Mischer. Typischerweise wird in statischen Mischern ein Längen- zu Durchmesserverhältnis im Bereich von 5 oder mehr vorgesehen, um eine gute Dispergierung zu erreichen. Bei Prozessen in Rührkesseln erfolgt dieser Energieeintrag typischerweise auf niedrigerem Leistungsniveau aber dafür über sehr lange Rührzeiten. Insgesamt zeigt sich, dass Dispersionsprozesse in Rührkesseln oft höhere Gesamtleistungseinträge bedingen und sich wegen der langen Prozesszeiten schlecht zur Integration in kontinuierliche Prozesse eignen. Ausserdem sind sie aufgrund der verwendeten dynamischen Apparatur teurer und wartungsintensiver.So far, the dispersion has been done with conventional static mixers or with stirring elements. In both cases, a very large specific energy input into the fluid mixture is normally necessary to achieve the desired drop sizes. In processes with static mixers, this large specific power input occurs over a very high product shear during the short time that the fluid mixture is in the static mixer. This large shear causes a large pressure drop across the static mixer. Typically, a length to diameter ratio in the range of 5 or more is provided in static mixers to achieve good dispersion. In stirred tank processes, this energy input typically occurs at a lower power level, but over very long stirring times. Overall, it can be seen that dispersion processes in stirred tanks often require higher total power inputs and, because of the long process times, are poorly suited for integration into continuous processes. In addition, they are more expensive and more maintenance-intensive due to the dynamic equipment used.

Aufgabe der Erfindung ist es, eine Dispergierung von Gasen in Flüssigkeiten oder Flüssigkeiten in anderen, nicht mischbaren Flüssigkeiten mit niedrigerer spezifischer Dispergierleistung zu erreichen.The object of the invention is to achieve a dispersion of gases in liquids or liquids in other, immiscible liquids with lower specific dispersing power.

Die Aufgabe der Erfindung wird durch ein Dispergierelement gelöst, welches einen Kanal umfasst, in welchem ein Einsatzelement umfassend eine Schaumstruktur angeordnet ist. Insbesondere kann das Einsatzelement eine Schaumstruktur enthalten, die offenporig ist. Unter einer Schaumstruktur, die als offenporig charakterisiert ist, soll nachfolgend eine Schaumstruktur verstanden werden, bei denen die einzelnen Poren nicht durch Wände voneinander getrennt sind. Die Pore kann als Loch oder Hohlraum angesehen werden. Es existieren grosse Öffnungen zwischen angrenzenden Poren, durch die ein Fluid strömen kann. Für eine offenporige Schaumstruktur sind die Wände zwischen den Poren praktisch vollständig eliminiert. Die Öffnungen in den Wänden sind so gross, dass von der Wand nur noch ein Steg bestehen bleibt, der die Randbegrenzung benachbarter Poren bildet. Selbstverständlich kann eine Mehrzahl von Stegen vorgesehen sein.The object of the invention is achieved by a dispersing element comprising a channel in which an insert element comprising a foam structure is arranged. In particular, the insert element may contain a foam structure which is open-pore. A foam structure which is characterized as open-pored is to be understood below to mean a foam structure in which the individual pores are not separated from one another by walls. The pore can be considered a hole or cavity. There are large openings between adjacent ones Pores through which a fluid can flow. For an open-pore foam structure, the walls between the pores are virtually completely eliminated. The openings in the walls are so large that only one web of the wall remains, which forms the boundary of adjacent pores. Of course, a plurality of webs may be provided.

Die Schaumstruktur kann ein Metall, eine Metallegierung, insbesondere eine Aluminiumlegierung, eine Keramik, Glas, Kohlenstoff und/oder einen Kunststoff umfassen. Diese Schaumstruktur hat den Vorteil, dass sie eine sehr grosse innere Oberfläche aufweist, die zum Aufbrechen und Zerkleinern der Phasengrenze genutzt werden kann.The foam structure may comprise a metal, a metal alloy, in particular an aluminum alloy, a ceramic, glass, carbon and / or a plastic. This foam structure has the advantage that it has a very large inner surface that can be used for breaking up and crushing the phase boundary.

Die Schaumstruktur kann eine Porengrösse bis einschliesslich 100 PPI aufweisen. PPI ist ein übliches Mass zur Charakterisierung der Porengrösse einer Schaumstruktur. Es ist die Abkürzung für "Pores per Inch". Besonders bevorzugt liegt die Porengrösse in einem Bereich von 10 bis einschliesslich 100 PPI.The foam structure may have a pore size up to and including 100 PPI. PPI is a common measure for characterizing the pore size of a foam structure. It is the acronym for "Pores per Inch". Most preferably, the pore size ranges from 10 to 100 PPI inclusive.

Die freien Volumenanteile der Schaumstruktur, die für das Dispergierelement zum Einsatz kommen kann, betragen von 40 bis zu 97%, vorzugsweise von 50% bis zu 95%.The free volume fractions of the foam structure which can be used for the dispersing element are from 40 to 97%, preferably from 50% to 95%.

Eine Schaumstruktur kann mittels verschiedener Verfahren hergestellt werden. Beispielsweise kann in einem ersten Verfahrensschritt ein offenporiger Polyurethanschaum als Vorlage verwendet werden. Ein wesentlicher Vorteil bei der Verwendung eines Polyurethanschaums besteht darin, dass unterschiedlichste Formen und Porengrössen definiert industriell hergestellt werden können. Aus dem Polyurethanschaum kann in einem zweiten Verfahrensschritt eine Gussform für Leichtmetallguss mit verlorener Form hergestellt werden. Diese Gussform enthält die gewünschte Schaumstruktur. Auch CVD Techniken oder andere Verfahren, die auf Polyurethanschäumen als Vorläufer basieren, werden in der Industrie zur Erzeugung von Schaumstrukturen eingesetzt. Ausserdem sind verschiedene andere Verfahren zur Erzeugung von offenporigen Schaumstrukturen in der Entwicklung oder schon im Einsatz. Alternativ kann eine Schaumstruktur auch computergestützt mittels Rapid Manufacturing Techniken aus verschiedenen Materialien, insbesondere den oben genannten, hergestellt werden.A foam structure can be produced by various methods. For example, in a first process step, an open-pored polyurethane foam can be used as a template. An essential advantage of using a polyurethane foam is that a wide variety of shapes and pore sizes can be produced industrially. From the polyurethane foam can be produced in a second process step, a mold for light metal casting with lost shape. This mold contains the desired foam structure. Also, CVD techniques or other methods based on polyurethane foams as precursors are used in the industry to produce foam structures. There are also different ones other methods of producing open-pore foam structures in development or already in use. Alternatively, a foam structure can also be produced computer-assisted by means of rapid manufacturing techniques of different materials, in particular those mentioned above.

Erstaunlicherweise kann durch den Einsatz einer Schaumstruktur zum Dispergieren der notwendige Leistungseintrag für die Dispergierung reduziert werden. Dadurch können kompakte Dispergierelemente gebaut werden. Hierbei bedeutet kompakt, dass die Länge des Dispergierelements im Vergleich zu der Länge eines statischen Mischers reduziert ist. Die Reduktion der Länge kann zwischen 5 und 99% liegen. Das Einsatzelement weist eine Länge L und einen Durchmesser D auf, wobei das Verhältnis L/D kleiner als 5, vorzugsweise kleiner als 3, besonders bevorzugt kleiner als 2 ist. Überraschenderweise gelingt es mit einem Verhältnis L/D von kleiner als 5, Dispersionen von gleicher Qualität wie mit dem aus dem Stand der Technik vorbekannten statischen Mischer herzustellen.Surprisingly, by using a foam structure for dispersion, the necessary power input for the dispersion can be reduced. As a result, compact dispersing elements can be built. Here, compact means that the length of the dispersing element is reduced compared to the length of a static mixer. The reduction in length can be between 5 and 99%. The insert element has a length L and a diameter D, wherein the ratio L / D is less than 5, preferably less than 3, more preferably less than 2. Surprisingly, with a ratio L / D of less than 5, it is possible to produce dispersions of the same quality as with the static mixer previously known from the prior art.

Da die Schaumstrukturen kaum eine Mischwirkung aufweisen, können Kombinationen von statischen Mischelementen zur Makrovermischung und Vordispergierung mit zumindest einem Einsatzelement, welches eine Schaumstruktur enthält, zu einer Dispergiereinheit zusammengestellt werden. Die Dispergiereinheit kann auch die Wirkung als Homogenisiereinheit einschliessen. Dispergiereinheiten enthaltend ein Einsatzelement, welches eine Schaumstruktur enthält, eignen sich zur Erzeugung von Emulsionen, Dispersionen oder Schäumen. In dieser Anmeldung steht der Begriff Dispersion für Systeme, in denen Tropfen und/oder Blasen grösser als etwa 50-100 Mikrometer gross sind. Der Begriff Emulsion wird für Systeme mit kleineren Tropfen und/oder. Blasen verwendet.Since the foam structures have hardly any mixing effect, combinations of static mixing elements for macro-mixing and predispersion with at least one insert element containing a foam structure can be combined to form a dispersion unit. The dispersing unit may also include the effect as a homogenizing unit. Dispersing units comprising an insert element which contains a foam structure are suitable for producing emulsions, dispersions or foams.

Das Dispergierelement kann entweder zur Verarbeitung von schon vorgemischten oder vordispergierten Fluidsystemen eingesetzt werden oder die zu dispergierende Flüssigkeits- oder Gasphase wird bei der Verarbeitung hinzu dosiert. Falls das zu dispergierende Fluid zudosiert wird, kann zumindest ein Dosierelement in den Kanal münden, in welchem das Dispergierelement angeordnet ist. Das Dosierelement dient zum Eintrag eines Fluids in die im Kanal strömende erste Flüssigkeit. Das Fluid kann ein Gas oder eine zweite Flüssigkeit sein. Insbesondere strömen das Fluid und die erste Flüssigkeit im Gleichstrom durch den Kanal.The dispersing element can either be used for processing already premixed or predispersed fluid systems, or the liquid or gas phase to be dispersed is metered in during processing. If the fluid to be dispersed is metered in, at least one metering element can open into the channel in which the dispersing element is arranged. The metering element serves to introduce a fluid into the first liquid flowing in the channel. The fluid may be a gas or a second liquid. In particular, the fluid and the first fluid flow in cocurrent through the channel.

Das Dosierelement ist vorteilhafterweise stromaufwärts des Dispergierelements angeordnet. Es ist auch möglich, ein Dosierelement in die Dispergierelemente einzubauen. Zur gleichmässigen Verteilung der zu dispergierenden Phase kann auch eine Mehrzahl von Dosierelementen in den Kanal münden oder in der Dispergierelement eingebaut werden.The metering element is advantageously arranged upstream of the dispersing element. It is also possible to install a metering element in the dispersing elements. For uniform distribution of the phase to be dispersed, it is also possible for a plurality of metering elements to open into the channel or to be installed in the dispersing element.

Das Dosierelement kann als ein Rohr mit Dosieröffnungen ausgestaltet sein. Das Dosierelement kann als eine Kapillare ausgestaltet sein, die eine Dosieröffnung umfasst, die beispielsweise als eine Düse ausgebildet sein kann. Im Bereich der Dosieröffnung kann eine Krümmung vorgesehen sein, damit die zu dispergierende Phase sich optimal im Dispergierelement verteilen kann. Zur besseren Verteilung der zu dispergierenden Phase kann die Zuleitung eine Mehrzahl von Dosierelementen speisen, sodass die Anzahl der im Kanal angeordneten Einspeispunkte für die zu dispergierende Phase erhöht wird.The metering element can be designed as a tube with metering openings. The metering element can be designed as a capillary, which comprises a metering opening, which can be designed, for example, as a nozzle. In the area of the metering opening, a curvature can be provided so that the phase to be dispersed can be distributed optimally in the dispersing element.

Das Verfahren zur Erzeugung einer Dispersion gemäss der Erfindung umfasst folgende Schritte: in einem ersten Schritt wird eine erste Flüssigkeit und gleichzeitig ein zweites Fluid in den Kanal eingeleitet, wobei die erste Flüssigkeit mit dem zweiten Fluid in einem zweiten Schritt in einem Dispergierelement in Kontakt gebracht wird, wobei das Dispergierelement ein Einsatzelement, welches eine Schaumstruktur enthält, umfasst, die in dem Kanal angeordnet ist, wobei die erste Flüssigkeit und das zweite Fluid im Gleichstrom durch das Dispergierelement geleitet werden, wobei die erste Flüssigkeit und das zweite Fluid durch das Einsatzelement geleitet werden, wodurch das zweite Fluid in die erste Flüssigkeit dispergiert wird.The method for producing a dispersion according to the invention comprises the following steps: in a first step, a first liquid and at the same time a second fluid are introduced into the channel, wherein the first liquid is brought into contact with the second fluid in a second step in a dispersing element wherein the dispersing element comprises an insert member containing a foam structure disposed in the channel, wherein the first liquid and the second fluid are co-directed by the dispersing element, the first liquid and the second fluid being passed through the insert member , whereby the second fluid is dispersed in the first liquid.

Das Verfahren zur Erzeugung einer Dispersion aus einer unmischbaren oder schlecht mischbaren Flüssigkeit in einer anderen Flüssigkeit oder einem Gas in einer Flüssigkeit wird z.B. bei der Herstellung von Emulsionen bei Lebensmitteln, Haushaltprodukten oder Kosmetik angewendet. Auch bei der Erzeugung grosser Oberflächen für Reaktionen, dem Lösen eines Gases in einer Flüssigkeit, wie beispielsweise der Wasserbehandlung durch Ozon, ist eine Dispergierung erforderlich.The process for producing a dispersion of an immiscible or poorly miscible liquid in another liquid or gas in a liquid is described e.g. used in the preparation of emulsions in food, household products or cosmetics. Also in the generation of large surfaces for reactions, the dissolution of a gas in a liquid, such as the water treatment by ozone, a dispersion is required.

Neben der Dispergierleistung ist auch der Energieeintrag in die Dispersion massgebend, dank der besseren Dispergierleistung von Schaumstrukturen können gleichwertige Resultate mit geringerem Energieeintrag in die Dispersion erzeugt werden. Der Energieeintrag liegt überraschenderweise um bis zu 99% niedriger als bei statischen Mischern aus dem Stand der Technik.In addition to the dispersing power, the energy input into the dispersion also plays a decisive role. Thanks to the better dispersing performance of foam structures, equivalent results can be achieved with less energy input into the dispersion Dispersion can be generated. The energy input is surprisingly up to 99% lower than in static mixers from the prior art.

Dieses Ausführungsbeispiel ist nur ein exemplarische Darstellung einer möglichen Anordnung von Dispergierelementen und statischen Mischern zu einer Dispergiereinheit, die Erfindung ist in keiner Weise als auf dieses Ausführungsbeispiel beschränkt anzusehen.This embodiment is only an exemplary illustration of a possible arrangement of dispersing elements and static mixers to a dispersion unit, the invention is in no way to be regarded as limited to this embodiment.

Fig. 3 zeigt ein Beispiel für eine Schaumstruktur die offenporig ist. Der in Fig. 3 dargestellte Ausschnitt kann beispielsweise in eine der Schaumstrukturen gemäss Fig. 1 oder Fig. 2 integriert sein. Die Pore ist ein Loch oder Hohlraum welche In Fig. 3 durch die Eckpunkte 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 begrenzt. Die einzelnen Poren sind nicht durch Wände voneinander getrennt. Beispielsweise ist die Fläche, welche von den Eckpunkten 11, 12, 13, 14, 15 aufgespannt wird, als eine Öffnung 21 ausgebildet. Diese Öffnung 21 befindet sich zwischen der oben genannten Pore und der zeichnerisch nicht dargestellten vor der Zeichenebene liegenden Pore. Angrenzende Poren können durch die Öffnungen von einem Fluid durchströmt werden. Die Öffnung 21 wird durch Stege 22, 23, 24, 25, 26 begrenzt, welche die Randbegrenzung benachbarter Poren bilden. Fig. 3 shows an example of a foam structure which is porous. The in Fig. 3 shown section can, for example, in one of the foam structures according to Fig. 1 or Fig. 2 be integrated. The pore is a hole or cavity which in Fig. 3 by the corner points 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 limited. The individual pores are not separated by walls. For example, the surface, which is spanned by the corner points 11, 12, 13, 14, 15, formed as an opening 21. This opening 21 is located between the above-mentioned pore and the drawing not shown before the plane lying pore. Adjacent pores can be traversed by the openings of a fluid. The opening 21 is bounded by webs 22, 23, 24, 25, 26, which form the boundary boundary of adjacent pores.

Die Praxis zeigt, dass beim Einsatz von Schaumstrukturen zur Dispersion im Gleichstrombetrieb kaum eigentliche Maldistribution auftritt und die grosse innere Oberfläche der Schaumstruktur zu einer sehr effizienten Dispergierung führt. Zur grossskaligen Vermischung eignet sich die Schaumstruktur nicht. Unter grossskaliger Vermischung versteht man dabei einen Mischprozess, bei dem Fluid über grössere Distanzen senkrecht zur Hauptströmungsrichtung bewegt und durch die Bewegungen des Fluids Inhomogenitäten der Verteilung der einzelnen Komponenten im Fluid in Ebenen senkrecht zur Hauptströmungsrichtung ausgeglichen werden. Deswegen ist eine Kombination von klassischen statischen Mischelementen zur grossskaligen Vermischung und Vordispergierung und Schaumstrukturen zur Feindispergierung vorteilhaft. Einen ähnlichen Effekt kann man durch die Kombination von Abschnitten aus Schaumstrukturen unterschiedlicher Porendichte erreichen.Practice shows that the use of foam structures for dispersion in DC operation hardly actual Maldistribution occurs and the large inner surface of the foam structure leads to a very efficient dispersion. For large-scale mixing, the foam structure is not suitable. By gross-scale mixing is meant a mixing process in which fluid is moved over greater distances perpendicular to the main flow direction and inhomogeneities of the distribution of the individual components in the fluid in planes perpendicular to the main flow direction are compensated by the movements of the fluid. Therefore, a combination of classical static mixing elements for large - scale mixing and predispersion and foam structures for Fine dispersion advantageous. A similar effect can be achieved by combining sections of foam structures with different pore densities.

Es ist auch möglich, eine Kugelpackung einzusetzen, welche ebenfalls offenporig ist. Ein wesentlicher Unterschied von Kugelpackungen zu den Schaumstrukturen, wie vorhin beschrieben, liegt darin, dass Kugelpackungen typischerweise 25-40% freies Volumen und somit ein deutlich schlechteres Verhältnis von Volumen zu Oberfläche sowie grössere Druckverluste aufweisen. Die beschriebenen Schaumstrukturen haben ein freies Volumen von 40 bis zu einschliesslich 97%.It is also possible to use a ball packing, which is also porous. An essential difference of ball packages to the foam structures, as described above, is that ball packages typically have 25-40% free volume and thus a significantly poorer volume to surface ratio and greater pressure drops. The foam structures described have a free volume of from 40 up to and including 97%.
