Title (EN) AERATION INSTALLATION
(FR) INSTALLATION D'AERATION
Abstract:
(EN) The aeration of dispersions, particularly the aeration of suspensions of fibre materials in a floating installation (1) is effected by means of a ring injector (2) to which air is supplied through air supply channels (11) up to the mixture line (4). The ring-shaped slot which is formed in the ring injector (2) is thus aerated inside and outside. The middle piece (7) which is tapered in the direction of the largest free cross-section (Q4) of the ring injector (2) is provided with a fin (56) preventing the rotation of the dispersion.
(FR) L'aération de dispersions, en particulier l'aération de suspensions de matières fibreuses dans une installation de flottage (1) est effectuée au moyen d'un injecteur annulaire (2) auquel l'air est amené par des canaux d'amenée d'air (11) jusque dans le parcours de mélange (4). La fente annulaire qui se forme dans l'injecteur annulaire (2) est ainsi aérée à l'intérieur et à l'extérieur. La pièce médiane (7) qui se rétrécit en direction de la plus grande section transversale libre (Q4) de l'injecteur annulaire (2) est dotée d'une nageoire (56) empêchant la rotation de la dispersion.
