Abstract:
1. Distributor for a rotary filter comprising filtration cells rotating in a circular movement, comprising (a) a fixed collector part comprising at least two compartments, which each have an upward opening in the form of an arc of a circle and at least one liquid discharge pipe, and a central separator chamber, which comprises a downward opening putting the separator chamber in communication with each of the compartments and a gas discharge pipe, the said downward opening being disposed at a level lower than the upward opening of each of the compartments, (b) a movable distributor part which slides over the collector part during the said circular movement and which comprises, per filtration cell, an alveolus having an inlet for receiving a filtered liquid/gas mixture coming from the filtration cell and an outlet which passes opposite the arc-shaped opening in each of the compartments during the circular movement, thus allowing passage of the mixture in the collector part, and (c) means for putting the separator chamber under negative pressure, so as to cause a separation of gas from the liquid/gas mixture flowing in the said compartments of the collector part, with an upward movement of the gas in the separator chamber from its downward opening, characterised in that, in vertical projection, the downward opening of the central separator chamber and the upward opening of each compartment of the collector part overlap partially.
