Abstract

Die Erfindung betrifft einen statischen Mischer, umfassend einen sich in einer Hauptrichtung (X) erstreckenden Kanal (1) mit zumindest einem darin angeordneten Mischglied (4), wobei das Mischglied (4) Strukturen (6, 7) zur Aufteilung, Umlenkung und/oder Zusammenführung eines durch den Kanal (1) geförderten Medienstroms umfasst, wobei zumindest eine aufteilende Struktur (6, 7) den Medienstrom in zumindest einen ersten Teilstrom und einen zweiten Teilstrom aufteilt, wobei der erste Teilstrom und der zweite Teilstrom von der aufteilenden Struktur (6, 7) bis zu einer Zusammenführung verschiedene mittlere Weglängen aufweisen.

The invention relates to a static mixer comprising a channel (1) extending in a main direction (X) with at least one mixing element (4) arranged therein, the mixing element (4) having structures (6, 7) for dividing, deflecting and / or Merging a through the channel (1) funded media stream comprises, wherein at least one dividing structure (6, 7) divides the media stream into at least a first partial stream and a second partial stream, wherein the first partial stream and the second partial stream of the dividing structure (6, 7) have different average path lengths until a merge.
