Distributor for rotary filter and rotary filter equipped therewith

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.
