Description

one

The invention relates to continuous extraction apparatus. used for extraction in a liquid-liquid system, and can be used in the chemical, petrochemical and other industries.

Rotary extractors for a liquid-liquid system, including an exterior vertical cylindrical body, tO partitioned by height by separating plates or half rings, a rotor with mixing devices and fittings for input and output of liquid phases 1.15 are known.

Also known is a rotary extractor containing a vertical cylindrical body, upper and lower settling Kaglers that are connected to the housing, coaxially mounted in the housing 20 for rotation of a cylindrical rotor, fixedly mounted along the axis of the housing inside the rotor, stator half rings, fixedly mounted on the shaft and inner-25 body shells, mixing devices and fittings for input and output of phases 2.

In the known extractors, when the rotor rotates, a capture occurs.

the motion of the fluid in it, its rotation and agitation in the agitators. However, the rotational speed of the treated fluids decreases as the fluid moves away from the rotor walls and in the center becomes insignificant, therefore, the mixing intensity decreases. This is especially noticeable in the central part of the rotor between the mixing devices. An increase in the rotational speed of the rotor in order to increase the rotational speed of the processed fluids in the central part of the rotor leads to the separation of liquids in the region adjacent to the rotor surface under the action of centrifugal force and the existing difference in their densities. Thus, in the known extractors it is impossible to obtain a uniform distribution of the dispersible phase inside the rotor over its cross section neither at a low speed of its rotation, nor at a high one.

In addition, the placement of the mixed devices on a stationary shaft leads to a decrease in the flow area of the rotor, therefore, to a decrease in the productivity of the apparatus per unit area.

The purpose of the invention is to intensify the process by rational use of the entire volume of the hull and ensuring turbulent pulsations.

ETa c; spruce-e-ts by the fact that the extractor is equipped with vertical partitions attached to the stator yolokoltsa inside the rotor with bokosa of the rims, placed against the mixing devices that are placed on the outer and inner surfaces of the rotor, and the device is spaced on the inside the surface of the rotor, made in the form of radially curved

And 8 partitions passing through the notches 7; A part of the processed fluids is drawn to the axis of the rotor. In this way, circulating flows are formed, providing intense turbulent pulsations throughout the entire volume of the rotating rotor. The mixing of the liquids between the body and the rotor is based on the devices 9 located on the outer surface of the rotor. Liquids are captured by them and, under the action of centrifugal force, are thrown against the walls of housing 1. The fluids to be processed are delivered to the rotor 4 wall from the inner layers when devices 9 are displaced. Thus, a pulsating circulation motion of the fluids being processed is created, ensuring the existence of intense turbulent pulsations.

In intensive mixing, one of the phases becomes dispersed and, in the form of droplets, evenly spreads to the other. The droplets of the dispersed phase, having passed the mixing zooi excusator, are coalesced in. settling chamber 2 or 3.
