DEVICE FOR WASTE WATER TREATMENT FROM EMULSIFIED OIL PRODUCTS Russian patent published in 2021 - IPC B01D17/38 B04B1/08 

FIELD: machine building.

SUBSTANCE: invention relates to metallurgical, machine building, petrochemical industry and can be used for purification of waste water from oil products, for separation of heterogeneous liquids in petrochemical, machine building, metallurgical and biotechnological industries. Invention relates to an apparatus for treating waste water from emulsified petroleum products, comprising solid impurities, comprising a housing with inlet openings, rotor to create centrifugal force, inlet branch pipe and branch pipes for oil and water, shaft has vertical design, rotor-separator consists of tray holder, stack of trays, cover, lower and upper parts of the rotor housing are made in the form of a truncated cone, channels for removal of water with solid impurities are in the lower part of the housing, and in the upper part - channels for oil removal. In the first row of plates there are at least six holes of regular hexagonal shape and diameter from 0.3 to 0.5 mm, each hole is made in the place where the truncated cone rib is divided into two unequal parts, upper part is 90%, and lower 10% of length of rib of truncated cone, in rotor is additionally installed a second stack of plates, which is fixed on holder of second row of trays, which is rigidly fixed on inner wall of rotor, first and second stacks of trays are installed at distance with a gap between them from 2 to 5 mm, plates in packages are installed at angle of 45°, additionally a piston pump is fixed on the shaft under the rotor, and an electric motor is installed on the top of the housing.

EFFECT: higher efficiency and improved quality of water-oil emulsion separation by the device.
