    A process for the production and maintenance of a fluidized layer in a heterogeneous system includes the steps of: (1) setting a heterogeneous mass stream having a liquid as the continuous phase and a solid and/or gas as the disperse phase into fluidized motion in a column between two plates arranged superimposed and inclined in opposition to each other with respect to the horizontal, said plates forming a fluidizing cell and said fluidized motion being promoted by the force of gravity; (2) enriching a heavier phase above the lower plate, especially in the lower region thereof, and causing said heavier phase to flow from there into the space below the lower plate; (3) enriching a lighter phase below the upper plate, especially in the upper region thereof, and causing the lighter phase to flow from there into the space above the upper plate and/or to be discharged from there from the column; and (4) conducting the disperse phase in case of a density higher than that of the continuous phase, in a direction from the top toward the bottom through the column; or (5) conducting the disperse phase in case of a density lower than that of the continuous phase, in a direction from the bottom toward the top through the column.

    (54) MULTI SECTION COUNCIL FOR MASS TRANSFER
    /
    The invention relates to mass transfer devices, it can be used for carrying out processes in heterogeneous systems in which one of the phases is solid and the other is dispersed, especially if the dispersed phase is solid particles.
    Column mass transfer apparatuses are known in the art which contain plates or partitions in the body that do not cover the whole body cross section and serve to direct the movement of liquids 1. In addition, partitions are installed in order to reduce fluid circulation
    in the vertical direction, KOTcipeili
    occurs in the absence of a partition wall) k.
    Closest to the present invention is a multisection column equipped with nozzles for supplying and discharging substances and oppositely inclined plates, which are equipped with holes 2 and 2 and the upper edge of the column. In this column, the light phase flows through the wrinkle at the upper edge of the inclined plate, and The desired phase is through holes at the bottom edge. Such a primitive action provides
    It induces the circulation and formation of vortex phase motion.
    However, the well-known column is characterized by the possibility of a light phase breakthrough along the wall of the column. In addition, the process of circulation and vortex formation is uncontrollable, and this narrows the field of application of the column, as it reduces its versatility.
    The purpose of the invention is to intensify mass transfer.
    In the proposed column, vortices are formed more intensively, the breakthrough of the light phase is prevented, and conditions are created for the controlled control of the internal circulation process and the vortex pattern.
    This is achieved by installing a guide element over the hole of the top edge of the plate.
    FIG. 1 shows the proposed column with the indication of phase boundaries; in fig. 2 - the same, section aa in figure 1; in fig. 3 and 4 are two variants of plates.

    In case 1 of the proposed column, there are laid sloped tarp. 2, made with holes 3 and 4 for the flow of phases. Above the top opening 4 a guide element 5 is installed. For example, a flat plate. The column is equipped with nozzles b and 7 cc and the water supply respectively. In FIG 3, an iso6ra) en variant of the disassembled plate; on the upper stjern of which, using a distant element 8, a guide element 5 is installed, having the shape of a segment of a circle, completely covering the entire upper opening 4, but also entering the plane of the dish, forming a channel 9. The portion 10 of the dish is horizontal and has additional holes 11 of rectangular shape. Below the upper hole 4 there is a regulating device 12, made in the form of a rotary bolt. . V The trolleys depicted in Fig. 4 are equipped with armor and devices 13, which prevent undesirable desiccation of the particles of solid mortality —Rools: rolls. The operation of the column is in e, 4SSii -: - i3iA; Vfei: ---.-..- ---- - i- --- -,, ..-,.: .- ... . „.... - -. following. The heterogeneous mass flow is the phase of which is indicated by: a double arrow, connect cBiepxy through a branch pipe.6. Inside the column, the heavy and light phases are concentrated respectively in the eoya (x below and ipae of the turbulence zone 14). More than the hard phase moves through the openings 3 and leaves the apparatus below, and the light phase passes up through the openings 4. With insufficient density difference between the heavy and Light phases get heterogeneous flow is forcedly pushed through the column with a pump.The proposed column can also work as an apparatus with transverse flows, in this case additional components can be fed through nozzles located under each plate. You or a stream enriched in one of the phases is diverted. Claims of the invention A multi-compartment mass-transfer column equipped with nozzles for supplying and discharging substances and oppositely inclined plates that have holes on the lower and upper edges, so that , in order to intensify mass transfer, they are equipped with a guiding element installed above the Hole of the upper .cir.
