Abstract

Es werden ein Verfahren und eine Vorrichtung zur schonenden kontinuierlichen Vermischung einer Tröpfchendispersion mit einer Flüssigkeit beschrieben, wobei die Flüssigkeit in Form einer Vielzahl feiner Flüssigkeitsstrahlen in die Tröpfchendispersion injiziert wird, so daß die kinetische Energie der Flüssigkeitsstrahlen auf kurze Entfernung von der Injektionsstelle dissipiert und die weitere Vermischung durch eine in dem Behälter erzeugte Umwälzströmung mit Schergeschwindigkeiten unterhalb 20/s erfolgt.

Figure 00000001
A method and a device for the gentle continuous mixing of a droplet dispersion with a liquid are described, the liquid being injected into the droplet dispersion in the form of a large number of fine liquid jets, so that the kinetic energy of the liquid jets dissipates at a short distance from the injection site and the other Mixing takes place by means of a circulating flow generated in the container with shear rates below 20 / s.
