Kombinierter Wärmeaustauscher und MischerCombined heat exchanger and mixer

Die Erfindung betrifft einen kombinierten Wärmeaustauscher und statischen Mischer, der insbesondere für photographische Emulsionen geeignet ist.The invention relates to a combined heat exchanger and static mixer, which is particularly useful for photographic emulsions suitable is.

Bei der Herstellung photographischer Materialien wird die Silber-Halogenid-Emulsion in einer Mischanlage mit photochemischen Zusätzen wie Farbkuppler, Sensibilisatoren, Stabilisatoren, versehen und anschließend in flüssigem Zustand auf eine la fende Bahn aufgetragen. Beim Auftrag hat die Emulsion in der Regel eine Temperatur zwischen 35 und 40°. Zu diesem Zweck müssen Temperiervorrichtungen eingebaut werden. Es hat sich nun herausgestellt, daß bei der Temperierung von photographischen Emulsionen im Gegensatz zu konventionellen Wärmeaustauschern besonders kritische Anforderungen gestellt werden. Photographische Emulsionen sind in besonderem Maße gegen Überhitzung empfindlich. Die Temperierung muß daher bei möglichst kleinen Temperaturdifferenzen zwischen Emulsion und Heizmedium erfolgen. Eine weitere Gefahr der Überhitzung besteht darin, daß die an der Grenzschicht des Wärmeaustauschers entlang strömende Emulsion gelliert, so daß der Wärmeübergang erheblich herabgesetzt wird. Es hat sich nun als günstig erwiesen, wenn die Mischung und Temperierung nicht wie bisher üblich in getrennten Schritten erfolgt, sondern gleichzeitig durchgeführt wird. Zu diesem Zweck wurden die bekannten statischen Mischer (siehe DT-OS 1 557 118) modifiziert und mit einem Wärmeaustauscher kombiniert.In the manufacture of photographic materials, the silver halide emulsion is mixed with photochemicals Additions such as color couplers, sensitizers, stabilizers, provided and then in a liquid state on a la fende web applied. When applied, the emulsion has in usually a temperature between 35 and 40 °. For this purpose, temperature control devices must be installed. It has it has now been found that in the tempering of photographic In contrast to conventional heat exchangers, emulsions are subject to particularly critical requirements. Photographic emulsions are particularly resistant to overheating sensitive. The temperature control must therefore be carried out with the smallest possible temperature differences between the emulsion and the heating medium take place. Another risk of overheating is that the heat exchanger along the boundary layer flowing emulsion gelled, so that the heat transfer is significant is reduced. It has now proven beneficial when Mixing and temperature control are not separate, as was previously the case Steps takes place, but is carried out simultaneously. For this purpose, the known static mixers (see DT-OS 1 557 118) were modified and equipped with a heat exchanger combined.

Die erfindungsgemäße Neukonstruktion ist dadurch gekennzeichnet, daß die Mischsegmente des rohrförmigen statischen Mischers an einem axialen Innenrohr angeordnet sind, das von dem Heiz-The new construction according to the invention is characterized in that the mixing segments of the tubular static mixer are arranged on an axial inner tube, which is from the heating

medium durchströmt wird.medium is flowed through.

Bezüglich der· Dimensionierung gelten folgende Überlegungen. Mit zunehmendem Innenrohrdurchmesser nimmt zwar der Wärmeaustausch zu, die Mischwirkung geht jedoch zurück. Es wurde nun überraschenderweise gefunden, daß das Verhältnis von Innenrohrdurchmesser C (Außenmaß) zur lichten Weite A des Außenrohres von 1 : 1 ,9 bis 1 : 2,3 variiert werden kann, ohne die optimalen Arbeitsbedingungen wesentlich zu ändern. Das Verhältnis von Mischsegmentdurchmesser A zu Mischsegmentlänge.. B wird vorteilhaft im Bereich von 1 : 1 bis 1 : 1,5 gewählt. Mit diesen Abmessungen wurden bei photographischen Emulsionen mit einer Viskosität von maximal 200 cp sehr gute Ergebnisse erzielt. Selbstverständlich kann der Mischer zusätzlich zu der Innenrohrbeheizung noch mit einem herkömmlichen äußeren Heizmantel ausgerüstet werden.With regard to the dimensioning, the following considerations apply. The heat exchange increases as the inner tube diameter increases to, but the mixing effect is reduced. It has now surprisingly been found that the ratio of Inner tube diameter C (outer dimension) to the clear width A of the Outer tube can be varied from 1: 1.9 to 1: 2.3 without to change the optimal working conditions significantly. The ratio of mixing segment diameter A to mixing segment length .. B is advantageously chosen in the range from 1: 1 to 1: 1.5. These dimensions were used for photographic emulsions very good results with a maximum viscosity of 200 cp achieved. Of course, in addition to the inner tube heating, the mixer can also be equipped with a conventional outer Heating jacket can be equipped.

Man sollte zunächst erwarten, daß der Wärmeaustausch bei einem in dieser Weise modifizierten statischen Mischer wegen der relativ kleinen Oberfläche des Innenrohres und wegen des radialen Temperaturgradienten längs eines Mischsegmentes ungünstig ist. In den Fällen, in denen eine Beheizung des Mischstrecke erforderlich war, wurde der statische Mischer daher bisher mit einem äußeren Heizmantel vecsehen. Vergleichsversuche der neuen Mischerausführung .(Innenrohrbeheizung) haben ergeben, daß der Wärmeaustausch gegenüber einem statischen Mischer mit Außenmantelheizung (bei gleicher PrimärIeistung) um 200 % gesteigert werden kann. Eine physikalische Erklärung für diese unerwartet große Steigerung steht noch aus. Vermutlich werden an den Mischsegmenten infolge der ständigen Umschichtungen und der damit verbundenen Grenzschichtstörungen besonders hohe Wärmeübergangszahlen erreicht.One should initially expect that the heat exchange in a static mixer modified in this way is unfavorable because of the relatively small surface area of the inner tube and because of the radial temperature gradient along a mixing segment. In those cases in which the mixing section had to be heated, the static mixer was therefore hitherto used with an external heating jacket. Comparative tests of the new mixer design (inner tube heating) have shown that the heat exchange compared to a static mixer with outer jacket heating (with the same primary output) can be increased by 200%. A physical explanation for this unexpectedly large increase is still pending. Presumably, particularly high heat transfer coefficients are achieved at the mixed segments as a result of the constant shifts and the associated boundary layer disturbances.

Die neue Kombination von statischem Mischer und Wärmeaustauscher gewährleistet ferner einheitliche Verweilzeitbedingungen für verschiedene Volumelemente der· photographischen Emulsion. Auf diese Weise konnte eine'Verbesserung der Homogenität undThe new combination of static mixer and heat exchanger also ensures uniform residence time conditions for different volume elements of the photographic emulsion. In this way, an improvement in homogeneity and

damit auch der Qualität der photographischen Emulsion erzielt werden. .thus also the quality of the photographic emulsion achieved will. .

Ein weiterer Vorteil des modifizierten Mischers ist die große mechanische Stabilität des inneren Mischeinsatzes. Die Stabilität ist wichtig beim Einsatz des Mischers bei der Herstellung photographischer Emulsionen. Der Mischer muß hier häufig in verdunkelten Räumen geöffnet und gereinigt werden. Die verbesserte Stabilität verhindert ein Verbiegen der Mischsegmente und damit ein Klemmen des Mischeinsatzes beim Wiederzusammenbau nach der Reinigung. Da eine Beschädigung des Mischeinsatzes nicht mehr zu befürchten ist, kann der Durchmesser der Mischsegmente praktisch mit dem Innendurchmesser des Außenrohres übereinstimmen. In diesem Fall sind die Mischbedingungen optimal. *Another advantage of the modified mixer is the great mechanical stability of the inner mixing insert. The stability is important when using the mixer in making photographic emulsions. The mixer often has to be in darkened rooms can be opened and cleaned. The improved stability prevents the mixing segments from bending and thus jamming of the mixing insert when reassembling after cleaning. Because damage to the mixing insert is no longer to be feared, the diameter of the mixing segments can practically match the inner diameter of the outer tube to match. In this case the mixing conditions are optimal. *
