CA 2038815

A device for separation of air from fiber suspensions of flotation devices which are heavily air- and foam-lades or represent a mixture of fluid and foam features a hydrocyclone whose inlet opening is arranged least 2.5 m below the outlet opening of the flotation device for the air-laden fluid or mixture. The separation section of the hydrocyclone is a slender, truncated cone-shaped body on whose pointed (thin) end the deaerated fluid is withdrawn. In this outlet opening there is a back pressure maintained, so that the inlet opening is not completely covered by the vortex of the fluid, leaving still a sufficiently free entrance cross section for the foam. Above the entrance section of the hydrocyclone a mechanical foam eliminator with a rotor is arranged, the rotor comprising an impeller wheel which is provided with radial blades. A funnel-shaped suction sooket feeds the foam-air mixture to the impeller wheel.

Un dispositif permettant de séparer l'air des suspensions de fibres produites par des dispositifs de flottation, qui sont chargées d'air ou de mousse ou qui représentent un mélange de fluide et de mousse, est constitué d'un hydrocyclone dont l'entrée est disposé à au moins 2,5 m au-dessous de la sortie du fluide ou du mélange chargé d'air du dispositif de flottation. La section de séparation de l'hydrocyclone est un mince cône tronqué dont l'extrémité pointue (petite) est le point de prélèvement du fluide désaéré. Comme on maintient une contre-pression dans cette sortie, l'entrée n'est pas complètement recouverte par le vortex de fluide; l'espace y est donc suffisant pour laisser pénétrer la mousse. Il y a, au-dessus de la section d'entrée de l'hydrocyclone, un dispositif anti-mousse comportant un rotor qui comprend une roue à lames radiales. Une tubulure d'aspiration en forme d'entonnoir achemine le mélange mousse-air jusqu'à la roue à lames.
