Description

one

The invention relates to equipment of chemical-technological processes and can be used to ensure contact and liquid-liquid phases of the IB phases.

A known centrifugal centrifugal apparatus contains a non-rotating core, a rotor with a sediment placed in it, and devices for input and output of phases.

A disadvantage of the known apparatus is the small size of the contact zone with respect to the total diameter: apparatus.

In order to increase the efficiency of the mass transfer by increasing the contact zone and eliminate slippage of the liquid between the rotor and the housing, the upper and lower rotor surfaces are bent radially and the side surfaces are vertical with the inner surfaces of the hull. Radial paws are connected to vertical ones. Lo-patches are made of a material with a low coefficient of friction, nalimer is made of fluorolast.

FIG. 1 diagrammatically shows the proposed apparatus; in fig. 2 is the same (section A-A "and Fig. 1.

The device consists of a housing 1 in which a rotor 2 is installed with aisles 3 on its periphery. The housing has a chamber 4, on it is fixed. Distribution device 5.

The rotor 2 contains the device 6, the channels 7 and the chamber 8. Radial vanes are located on the upper and lower surfaces of the rotor.

9, and on the cylindrical part - the blades

10. To improve the mass transfer effect, the poTOip can be equipped with a nozzle.

The machine works as follows.

The light liquid is supplied through the center drop of the device 5, passes into the channels 7 of the rotating rotor 2 and under the action of the developing centrifugal pressure in them goes through the hole to the periphery of the internal part of the rotor near the main level of the phase separation. Further, the light phase in the inner cavity of the rotor in the form of a split phase moves to the center of the rotor 2, flows into the chamber 8 and through the device 5 is removed from the apparatus.

Heavy liquid is supplied through device 5 to device 6, from which, under the action of centrifugal force, is sprayed into a layer of light liquid and moves in the form of droplets towards the periphery of the rotor 2, continuously in contact with the light liquid. Then, drops of heavy liquid, having reached the main level of the phase separation, coalesce and already in a continuous flow pass through passages 3 to the periphery of the rotor to the inner surface of the fixed case, from where they flow into chamber 4 and merge into the apparatus.

Thanks to the presence of a molded 9 and 10, the slip, lick, and removal of heavy liquid from n-iodo-mobile corius are eliminated, as a result of which its pressure in the space between the rotor and the housing increases. This leads to an increase in the size of the contact ash inside, the rotor.
