Abstract

Appareil cyclonaire à écoulement axial pour la séparation de particules en suspension dans un fluide, constitué par un corps tubulaire (10) comprenant un aubage (14) de mise en rotation à l'extrémité d'entrée du fluide à épurer, un dispositif de récupération de l'énergie cinétique du fluide à son autre extrémité, et un noyau (12) disposé dans l'axe du corps tubulaire, des fentes longitudinales (18) étant découpées dans la paroi du corps tubulaire, entre ses extrémités, pour l'évacuation des particules séparées. Axial flow cyclone device for separation of particles suspended in a fluid, consisting of a tubular body (10) comprising a blade (14) for rotating the inlet end of the fluid to be purified, a device for recovery of the kinetic energy of the fluid at its other end, and a core (12) arranged in the axis of the tubular body, longitudinal slots (18) being cut in the wall of the body tubular, between its ends, for the evacuation of separate particles.

Pour améliorer l'efficacité de séparation de ces appareils, notamment pour des particules dont les dimensions sont comprises entre 5 et 10 microns, la section du passage ménagé entre le corps tubulaire (10) et le noyau (12) a une section progressivement décroissante, de l'amont vers l'aval, dans la portion convergente (10a) du corps tubulaire, et une section progressivement croissante, de l'amont vers l'aval, entre l'extrémité amont de la portion divergente (10c) et l'extrémité de sortie du corps tubulaire. To improve the separation efficiency of these devices, especially for particles whose dimensions are between 5 and 10 microns, the section of the passage formed between the tubular body (10) and the core (12) has a section gradually decreasing, from upstream to downstream, in the portion convergent (10a) of the tubular body, and a section progressively increasing, from upstream to downstream, between the end upstream of the divergent portion (10c) and the end of exit from the tubular body.
