Abstract
Epurateur à hydrocyclone inversé (10) servant à la séparation par centrifugation des contaminants légers contenus dans une suspension de fibres de pâte à papier, constitué d'un corps creux allongé (12) de section transversale circulaire, convergeant de façon uniforme depuis une première extrémité d'entrée vers une deuxième extrémité de pointe, tel que le rapport de longueur du corps conique par rapport au diamètre le plus long est d'au moins environ 20 à 1, et définissant un angle d'ouverture inférieur à 3 degrés.
