Abstract
Description
Die Erfindung betrifft ein Verfahren zum Suspendieren und zum Behandeln von feinteiligen Feststoffen in Flüssigkeiten, beispielsweise mischen von Feststoffen in Flüssigkeiten, lösen von Feststoffen in Flüssigkeiten, extrahieren von Wertstoffen eines Feststoffes in eine Flüssigkeit, Reaktion eines Feststoffes mit einer Flüssigkeitskomponente und ähnliches.The invention relates to a method for suspending and treating finely divided solids in liquids, for example mixing solids in liquids, solving Solids in liquids, extracting valuable substances from a solid into a liquid, Reaction of a solid with a liquid component and the like.
Weiterhin wird eine Vorrichtung zur Durchführung dieses Verfahrens gegeben.Furthermore, a device for execution given this procedure.
Üblicherweise werden zum Suspendieren, Mischen und Behandeln von feinkörnigen bzw. feinteiligen Feststoffen in Flüssigkeiten Rühr-, Schüttel- oder Umlaufapparate eingesetzt. Bei zusätzlichem Gaseintrag findet auch das Air-Lift-Prinzip Anwendung. In allen diesen Fällen ist in der Regel ein relativ hoher spezifischer Energieeintrag erforderlich. Bei sehr kleinen Teilchen sind außerdem die gewünschten Effekte oft sehr gering.Usually are used to suspend, mix and treat fine-grained or finely divided solids in liquids stirring, Shake or Circulators used. With additional gas entry takes place also the Air-Lift principle application. In all of these cases usually a relatively high specific energy input is required. In the case of very small particles, the desired ones are also Effects often very little.
Im Sinn der Weiterentwicklung des Standes der Technik der betreffenden Prozesse sowie deren Effizienz wären hohe lokale Geschwindigkeiten, instationäre Fluidbewegungen mit hohen Relativgeschwindigkeiten und dieses bei niedrigem Energiebedarf wünschenswert. Diese Aufgabe wurde, wie im folgenden beschrieben, gelöst.In the spirit of the further development of State of the art of the processes concerned and their efficiency would be high local velocities, unsteady fluid movements with high Relative speeds and this with low energy consumption desirable. This problem was solved as described below.
Erfindungsgemäß wird die Flüssigkeit mit den kleinen Feststoffteilchen im Behandlungsapparat durch eine externe Pulsanregung in eine periodische Bewegung versetzt. Dabei gelingt es durch eine geeignete Wahl der Pulsationsbedingungen (Frequenz, Amplitude) und der Anlagengeometrie, die Feststoffteilchen in Bodennähe nach oben zu bewegen und in der Flüssigkeit gut zu verteilen. Durch eine richtige Bemessung der Anregungsfrequenz erreicht man einen Resonanzzustand der Schwingungsbewegung, wodurch eine energiesparende und sehr wirkungsvolle Fluidbewegung erhalten wird. Der Effekt des Suspendierens und Mischens bei diesen resonanten Fluidschwingungen ist durch ein Aufsteigen, Aufwirbeln und Hochschleudern der Feststoffteilchen vom Apparateboden bis in die oberen Bereiche der Flüssigkeit und durch eine den Prozess fördernde Relativgeschwindigkeit zwischen Feststoff und Flüssigkeit charakterisiert.According to the invention, the liquid with the small solid particles in the treatment apparatus through a external pulse excitation is set in a periodic movement. there succeeds through a suitable choice of pulsation conditions (frequency, amplitude) and the system geometry, the solid particles near the ground to move up and in the liquid good to distribute. By correctly dimensioning the excitation frequency one reaches a resonance state of the oscillatory motion, whereby receive an energy-saving and very effective fluid movement becomes. The effect of suspending and mixing on these resonant fluid vibrations is by rising, whirling up and hurling the solid particles from the bottom of the apparatus to the upper areas of the liquid and by promoting the process Relative speed between solid and liquid characterized.
