ABSTRACT:
Pollution separator and purifier apparatus (10) for at least one fluid mixture comprises: an inlet member (14) for admitting the fluid mixture to be treated into a stationary cylindrical body (12); a rotor mounted in the cylindrical body (12) and having a stack of at least two plates (18) with openings, cooperating with means that generate a pressure drop in the top portion of the apparatus and generating upward helical motion in the mixture to be treated; a hopper (22) for collecting the heavy phase, connected to the cylindrical body (12) beneath the rotor (16) and provided with forced evacuation means (24); and an extractor member (26) for extracting the treated mixture, and connected to the cylindrical body (12) above the rotor (16). The inlet member (14) is situated between the rotor (16) and the extractor member (26), and includes an annular chamber (28) connected to the annular gap (20) that exists between the periphery of the plates (18) and the wall of the cylindrical body (12), an inlet (30) for admitting the mixture to be treated into said annular chamber (28), and a central column (32). The apparatus includes means (26, 40, 42) for generating downward helical motion in the annular gap (20).
