Abstract
L'invention concerne un épurateur à vortex pour fractionner une suspension gazeuse ou liquide en plusieurs portions. Cet epurateur comporte une chambre à vortex ayant une partie convergente 3 formée de plusieurs sections A1-A8 ayant des sections transversales circulaires, disposées successivement dans le sens axial de la chambre et en communication directe les unes avec les autres, chaque section ayant un diamètre plus petit que la section immédiatement précédente à partir de la grande extrémité de la chambre, et ayant son centre décalé latéralement par rapport au centre de ladite section immédiatement précédente, ainsi que par rapport au centre de la section immédiatement suivante afin de former dans la partie de transition entre les zones un rebord en forme de croissant Application, notamment, à l'épuration de pâte pour la fabrication du papier.
