Abstract

Eine Gasabscheideanlage (1) zum Abscheiden von Gas aus Flotationsschaum umfasst mindestens einen Gasabscheideraum (4), in dem mindestens ein Teil des im Flotationsschaum enthaltenen Gases durch Zerstören von Gasblasen im Flotationsschaum aus dem Flotationsschaum abgeschieden wird. Im Gasabscheideraum (4) ist mindestens ein derartiger Abschnitt vorhanden, in dem die Querschnittsfläche des Gasabscheideraums (4) in Strömungsrichtung (A) eines in den Gasabscheideraum (4) zuzuführenden, Flotationsschaum enthaltenden Stroms sich verringernd angeordnet ist, um die Strömungsquerschnittsfläche für den Flotationsschaum enthaltenden Strom zu verringern. Weiterhin umfasst die Anlage (1) mindestens einen Flüssigkeitszuführungsblock (9), um Flüssigkeit in den im Gasabscheideraum (4) vorhandenen, Flotationsschaum enthaltenden Strom zum Zerstören von Gasblasen im Flotationsschaum zuzuführen.
