Abstract
Flüssigkeitsverteiler (110) in einer Vorrichtung zum Waschen von Zellulosepulpe, wobei der Flüssigkeitsverteiler eine Vielzahl von Einlassöffnungen (111a-b) umfasst, die entlang einer Längsrichtung des Flüssigkeitsverteilers verteilt sind. Jede Einlassöffnung ist mit einer Strömungsleiteinrichtung (112) versehen, die einen Schlitz für jede Einlassöffnung bildet, wobei der Schlitz eine tangentiale Öffnung (114) aufweist, die in eine tangentiale Richtung der Presswalze weist, wobei die Öffnung angrenzend an die Kammerwand (105) angeordnet ist, um die Strömung entlang einer Kammerwand der Vorrichtung zu leiten. Die Strömungsleiteinrichtungen von mindestens zwei benachbarten Einlassöffnungen können in Längsrichtung benachbarte Schlitze bilden, die durch eine Trennwand getrennt sind. Alternativ sind die Strömungsleiteinrichtungen (112) mit einer oder mehreren seitlichen Öffnungen (121) zwischen ihren Schlitzen versehen, wobei die eine oder mehreren seitlichen Öffnungen einen effektiven Gesamtströmungsquerschnitt aufweisen, der kleiner ist als das Doppelte des effektiven Strömungsquerschnitts jeder tangentialen Öffnung.
