Description

Vorrichtung zum Mischen von Gasen und Flüssigkeiten Gegenstand der vorliegenden Erfindung ist eine Vorrichtung zum Mischen von Gasen und Flüssigkeiten, die sich insbesondere zur Erzeugung von Schaum eignet, aber auch in allen Fällen vorteilhaft Anwendung finden kann, wo irgendeine Einwirkung eines Gases auf eine Flüssigkeit beabsichtigt ist. Bei solchen Vorrichtungen, welche aus einem Durchlaufbehälter bestehen, der einen körnigen oder feinporigen Verteilungs- oder Großoberflächenkörper enthält, durch welchen das Gas und die Flüssigkeit gleichzeitig unter Druck hindurchgeleitet werden, hat sich gezeigt, daß, wenn der Behälter glattwandig ist, der Widerstand, den das körnige oder feinporige Füllmaterial und der darin bereits erzeugte Schaum leistet, die neu zutretenden Stoffe veranlaßt, an den glatten Wänden entlang zu streichen, anstatt ihren Weg durch das Füllmaterial zu nehmen.Device for mixing gases and liquids is the subject of present invention is a device for mixing gases and liquids, which is particularly suitable for producing foam, but also in all cases Can be used advantageously wherever any action of a gas on a Liquid is intended. In such devices, which consist of a flow-through container consist of a granular or fine-pored distribution or large surface body contains, through which the gas and the liquid passed simultaneously under pressure it has been shown that if the container is smooth-walled, the resistance, the granular or fine-pored filling material and the foam already produced in it makes the newly arriving substances move along the smooth walls instead of making their way through the filler material.

Die Erfindung vermeidet den Nachteil, indem der Durchgangswiderstand längs der Behälterwand größer gehalten ist als der Durchgangswiderstand durch das Füllmaterial selbst, z. B. durch Bildung von tiefen Rillen in der inneren Behälterwandung oder durch Einbau vorspringender Ringe. Hierdurch ist erreicht, daß die zu mischenden Stoffe ihren Weg nahezu ausschließlich durch das Füllmaterial nehmen und nicht mehr an den Behälterwandungen entlang fließen. Gleichzeitig wird die Innenfläche der Behälterwandung vergrößert, so daß diejenigen Stoffteile, welche etwa doch ihren Weg längs der Innenwandung des Behälters nehmen, einen längeren Weg durchlaufen und infolgedessen zu einer ausreichenden Vermischung miteinander gelangen. Es hat sich gezeigt, daß durch die erfindungsgemäße Ausgestaltung der Behälterinnenwandung eine viel feinkörnigere Füllung verwendet werden kann. Eine derartige Verringerung des Korn maß es ist von besonderem Vorteil, weil die gegenseitige Durchmischung von Flüssigkeit und Gas um so inniger wird, je feinkörniger das Füllmaterial der Mischvorrichtung ist. Wird durch die beschriebene Vorrichtung eine Flüssigkeit und ein Gas gemeinsam hindurchgedrückt, so wird dank der Oberflächenspannung der Flüssigkeit diese durch das Gas in viele winzige Bläschen zerlegt, die in ihrer Gesamtheit einen Schaum von ungewöhnlicher Feinheit und Stabilität ergeben. The invention avoids the disadvantage by reducing the volume resistance is held along the container wall greater than the volume resistance through the Filler material itself, e.g. B. by forming deep grooves in the inner container wall or by installing protruding rings. This ensures that the to be mixed Substances make their way almost exclusively through the filling material and nothing more flow along the container walls. At the same time, the inner surface of the Container wall enlarged, so that those pieces of fabric, which are about theirs Take the path along the inner wall of the container, go through a longer path and consequently achieve sufficient mixing with one another. It has it has been shown that the inventive design of the inner wall of the container a much finer-grain filling can be used. Such a reduction of the grain measured it is of particular advantage because the mutual mixing of liquid and gas is the more intimate, the finer-grained the filler material Mixing device is. Is a liquid and by the device described If a gas is pushed through together, thanks to the surface tension of the liquid This is broken down by the gas into many tiny vesicles, which in their entirety form one Foam of unusual delicacy and stability result.
