Description

one

The invention relates to mass transfer apparatus designs used in the radiochemical industry.

Known extraction apparatuses Adeleanu, made in the form of successive sections connected by overflow channels, on which pumps are installed, each of the sections consisting of mixing and settling chambers, do not allow the processing of substances with a specific gravity difference of about 0.05 g / cm.

In order to process the reagents with a specific gravity difference of less than 0.05 g / cm, in the proposed mixer apparatus, the chamber is designed as a reaction zone of an extraction column, the axis of which is arbitrarily relative to the vertical axis, and for uniform mixing of the reagents at each point of the mixing chamber installed on overflow channels, equipped with pulsators.

FIG. 1 shows the proposed mass transfer apparatus; in fig. 2 - a mixing chamber with a longitudinal axis, having a vertical rotation.

The mass transfer apparatus consists of consecutive sections, each of which is divided by a partition U with an outlet 2 into a mixing chamber 3 and a settling chamber.

The mixing chamber 3 is connected to the settling chambers 4 of the adjacent sections by channels 5 and 6 for the flow of reagents. Pumps 7 and S supply clarified solutions.

Directly into the mixing chamber, the pressure cavities 9 and 10 of HiacocoB are in communication with the collectors 11 and 12, having hydraulic lock caps 13, equally distributed over the cross section. Mixing chamber filled

extraction nozzle 14 and communicated with the pulsator through its pulsation chamber 15 and pulsation collector 16. The reagents are fed into the mixing chambers of the outer sections: the heavy phase through the inlet pipe 17, lightly through the inlet pipe 18, the phases are distributed by collectors // and 12 through the section and move to the outlet 2 (in the present example, from bottom to top). In this case, the extraction unit 14

in combination with pulsation, ensures uniform distribution of droplets of the dispersed phase over the cross section of the mixing chamber.

Having passed the mixing chamber, the emulsion through the outlet 2 enters the settling chamber 4, where it is exfoliated by graphitization. The lightened phases enter the mixing chambers of adjacent sections: it is easy through the non-continuous channel 5 and the pump 7 with the collector 1 on the pressure cavity,

through the overflow channel 6, the pump 8 and the collector 12.

In the example, the residence time of the light phase is minimal. To increase the residence time of the light phase, the longitudinal axis of the mixing chamber can be rotated relative to the vertical axis (see Fig. 2).
