SUBSTANCE: centrifuge for separating liquid inhomogeneous media refers to process equipment intended for separating liquid inhomogeneous media in various industries into constituent fractions in the centrifugal force field. The centrifuge for separating liquid inhomogeneous media comprises a filter device mounted on the body-bottom base, consisting of a shell, an upper cover, and two shafts: a drive shaft and a supporting hollow shaft with radial openings and packs of removable membrane filter elements (PRMFE) and sets of turbolators. The PRMFE are secured through a spacer seal on the support shaft secured to the body-bottom. The set of turbulators through the regulating segments is mounted between the upper drive and lower support turbolators, and the upper drive turbolator is connected to a drive shaft concentrically coupled to the stationary support shaft. Rotation of the set of turbolators is provided through a pulley mounted on the shaft from an instrument electric motor mounted on a frame, and secure vertically through a belt gear. At that, the rotation occurs from 200 to 800 and from 800 to 2000 rpm. In addition, there is an opening for drilled in stationary shaft bottom for draining clean filtrate through a flange with a branch pipe. There are pipe connections for gauges, safety valves and an input connection pipe of initial mixture mounted on the upper cover.

SUBSTANCE: invention is referred to methods of increasing separation efficiency of solid and liquid phases during the centrifugal filtration performed in the tank (1) for centrifugal filtration. These methods lie in increase of overfall of pressure through a filtering deposit (6) with use of an exposure, such as gas introduction through an inlet pipe (9) for compressed air to augment pressure of gas in the filtering chamber, and/or the application of vacuum to an outer side of the filtering chamber. The external unit of increase in overfall of pressure is designed to augment speed of water removal during the drainage period at a centrifugal filtration and, hence, to reduce amount of residual water.
EFFECT: lowering of damp of the filtered deposit.
