The arrangement includes a first guide wall (4), which is arranged at a distance from that end wall (15) of the cell (1) that is located on the side of the feed end (2), in order to extend along the whole width of the cell with respect to the vertical direction at an inclined angle (α). The first guide wall includes a bottom edge (5), which is located at a distance (H 1 ...H 2 ) from the cell bottom, so that in between the bottom edge (5) and the cell bottom (3), there is left a clearance gap (6) widening from the center towards the cell sides. The second guide wall (7) is essentially parallel with the first guide wall (4) and placed at a distance (L1) therefrom, so that in between the first guide wall (4) and the second guide wall (7), there is formed an uptake shaft (8) extending diagonally upwards at an inclined angle (α). The second guide wall (7) includes a bottom edge (13), which is pressed tightly against the cell bottom (3), a number vertical slots (9), which are arranged as a horizontal line (10) of vertical slots, said line extending along the width of the second guide wall at a distance from the bottom edge (13), and a slanting plate (11), which is attached to the second guide wall (7), in the vicinity of the top part of the line (10)of vertical slots.

摘要： The invention relates to a method and arrangement for separating two solutions mixed in dispersion into two solution phases in a liquid-liquid extraction separation cell (1). The shut-off element (3, 4, 5) comprises a front panel (8) that extends along the whole width of the cell. The front panel (8) includes a bottom edge (9), which is arranged at a distance (H1 H2 H3) from the cell bottom (7), so that the front panel (8) allows an unobstructed flow of the heavier solution phase directly forwards underneath the bottom edge (9). In the vertical direction, the front panel extends to such a height that it forces the lighter solution phase placed on the heavier solution phase to flow as a thin overflow layer over the top edge (12) of the front panel (8) and forces the dispersion to thicken in front of the front panel. The rear panel (15) is essentially parallel with the front panel (8) and placed at a distance (S) therefrom, so that in between the front panel and the rear panel, there is formed an uptake shaft (14) extending essentially vertically upwards, along which uptake shaft the thickened dispersion can rise upwardly and be compressed. At least one slanting plate (16) is in the direction of the flow placed at an inclined angle (δ), inclined upwardly with respect to the horizontal plane. The slanting plate attenuates and slows down the vertical component of the rising compressed dispersion flow and guides the dispersion essentially in the lengthwise direction of the cell as a dispersion flow to the successive separator part.
