Abstract

In einer Vorrichtung zur Durchführung einer pneumatischen Flotation wird die begaste Trübe über eine Rohrleitung (16) in den unteren Bereich der Trennzelle (10) zu einer Druckaufbaudüse (19) geführt, die durch ihre Querschnittsverminderung in der begasten Trübe einen definierten Druck aufbaut, der zu einer Verkleinerung der Gasblasen führt. Die unter erhöhtem Druck stehende Trübe wird anschließend vor Eintritt in das Trenngefäß in einer Druckabbaukammer (21), die mit Trübeauslaßdüsen (22) versehen ist, entspannt.
