CA 2257869

A mixing device for fluids, comprising a column within which there is an internal core, a space between the column and core defining a channel for the flow of the fluids, the surface of the column facing the core having fluid guide elements which impart helical flow in a first twist direction upon a fluid flowing along the channel, the surface of the core having fluid guide elements thereon which impart helical flow in an opposite twist direction upon the fluid. On part of the channel, the helical flow imparted to the fluid is predominantly in the twist direction of the elements on the core and on a part of the channel upstream or downstream of this part the helical flow imparted to the fluid is predominantly in the twist direction of the elements on the column.

Dispositif mélangeur pour fluides comprenant une colonne dans laquelle est ménagé un élément central. Un espace situé entre la colonne et l'élément central définit un passage d'écoulement pour fluides. La surface de la colonne orientée vers l'élément central comporte des éléments de guidage de fluide qui engendrent un écoulement tourbillonnaire, dans un premier sens de rotation, dans un fluide s'écoulant dans le passage, et la surface de l'élément central comporte des éléments de guidage de fluide qui engendrent un écoulement tourbillonnaire, dans un sens de rotation opposé, dans ledit fluide. Dans une zone du passage, l'écoulement tourbillonnaire du fluide suit principalement le sens de rotation imparti par les éléments ménagés sur l'élément central, et dans une zone du passage située en amont ou en aval de la première zone, l'écoulement tourbillonnaire suit principalement le sens de rotation imparti par les éléments ménagés sur la colonne.
