Abstract

Der Zick-Zack-Sichter weist einen mit Luftzuführungen (4,9) versehenen Sichtraum auf, der in strömungstechnisch parallel geschaltete, zickzackförmige Kanäle (5) unter­ teilt ist, deren Länge 1 größer ist als ihre Breite b. Auf diese Weise wird ein Sichterpaket mit vielen kleinen Kanalquerschnitten gebildet. Dieses Bauprinzip erlaubt bei einer gleichen Zahl von Knickstellen wesentlich geringere Bauhöhen.
