CENTRIFUGE FOR SEPARATING MULTICOMPONENT LIQUID MEDIUM Russian patent published in 2000 - IPC

FIELD: equipment adapted for separating liquid medium containing oil fraction, which may be used in different branches of industry. SUBSTANCE: centrifuge has cylindrical-conical rotor, cylindrical membrane-type filter fixed within rotor and equipped with device for preliminary filtration of medium to be separated. Continuous cylindrical shell with end flanges is positioned in rotor concentrically and in spaced relation to cylindrical filter. Shell is adapted for separating light oil fraction. Auxiliary filter made in the form of cylindrical-conical chamber is arranged in fixed position under shell. Auxiliary filter walls are made in the form of membranes, which define with rotor wall and main filter wall gaps for flowing and discharge of separated phases. Centrifuge separates medium into four fractions. Construction of centrifuge provides self-recovery of membranes. EFFECT: increased efficiency and improved purity of separation of multicomponent medium. 2 cl, 1 dwg
