Method of separating particles contained in a laden fluid, and a dynamic separator for performing this method

Claim 1

A dynamic separator for separating particles from a particle-laden fluid, said separator having a rotor located in a fluid-tight enclosure embodying an inlet for the particle-laden fluid, an outlet for the purified fluid and, in its lower portion, an outlet for the particles, the rotor carrying a filtering cartridge of generally cylindrical form and coaxial with the axis of rotation of the rotor, comprising the improvement wherein the filtering cartridge has at its center an upstream space connected in a fluid-tight manner to the inlet for the laden fluid, the cartridge being constituted by a succession of filtering partitions arranged to form, alternately, on one hand, radial passages directly connecting the upstream space to a space outside the rotor and, on the other hand, transverse passages which are separated from the radial passages by filtering partitions, through which transverse passages purified fluid is extracted as a result of a suction created between the inlet and the outlet for the fluid, the transverse passages extending into a downstream space in the rotor connected in a fluid-tight manner to the outlet for the purified fluid.
