Abstract

Eine Gasabscheideanlage (1) zum Abscheiden von Gas aus Flotationsschaum umfasst mindestens einen Gasabscheideraum (6), wobei im Gasabscheideraum (6) mindestens ein Teil des im Flotationsschaum enthaltenen Gases durch Zerstören von Gasblasen im Flotationsschaum aus dem Flotationsschaum abgeschieden wird. Zur Anlage (1) gehört mindestens eine den Gasabscheideraum (6) begrenzende Konstruktion (5, 18, 30) oder eine im Gasabscheideraum (6) angeordnete Konstruktion, gegen die oder an der entlang ein im Gasabscheideraum (6) mit einer erhöhten Strömungsgeschwindigkeit zuzuführender, Flotationsschaum enthaltender Strom steuerbar zum Zerstören von Gasblasen im Flotationsschaum angeordnet ist.A gas separation plant (1) for separating gas from flotation foam comprises at least one gas separation space (6), wherein at least part of the gas contained in the flotation foam is separated from the flotation foam by destroying gas bubbles in the flotation foam in the gas separation space (6). The plant (1) includes at least one construction delimiting the gas separation space (6) (5, 18, 30) or a construction arranged in the gas separation space (6), against or against which a gas flow in the gas separation space (6), Flotationsschaum containing stream is controllably arranged to destroy gas bubbles in the flotation foam.
