An apparatus for separating immiscible liquids of various density is disclosed, comprising a plurality of pan-shaped elements, wherein all walls (6, 7, 8, 9) of each pan-shaped element (5) are inclined outwards. The pan-shaped elements (5) are arranged so that the distance (h) between bases (10) of the adjacent pan-shaped elements (5) is less than the height of their walls (6, 7, 8, 9). Each arrangement for evacuating one of the phases is fashioned as a substantially vertical passage (16) having an inlet (17) flow area greater than the outlet (18) flow area. The passage (16) is arranged so that the walls (20) thereof extend through the base (10) of the pan-shaped elements (5). The outlet (18) of the passage (16) is spaced from the base (10) of the pan-shaped element (5) at a distance greater than the inlet (17) of this passage (16). The passage (16) is provided with a flow control member (19).
The method and apparatus mixes two immiscible liquids A and O to form a dispersion and then pre-separates the dispersion into two fractions (A+o) and (O+a) in a spout. These two fractions are fed separately into a decanter with two separate compartments which continue to maintain the two fractions as separate. Within the two separate compartments the two fractions are further separated into two flows, A, O, a, and o, such that four flows exit the decanter.
A method for mixing and separating immiscible liquid salts and liquid metals in a centrifugal contractor. The method includes introducing the liquids into an annular mixing zone and intensely mixing the liquids using vertical vanes attached to a rotor cooperating with vertical baffles, a horizontal baffle, and bottom vanes attached to the contactor housing. The liquids enter the contactor in the range of 700-800 degrees Celsius. The liquids are separated in the rotor into a dense phase and a light phase which are discharged from the contactor.
Settleable-particles are separated from a dirty flow of settleable-particles and fluid by trays having a planar section configured with opposed ends and opposed sides, and an entrance edge and an exit edge on opposed ends. The section has opposed side edges, and an upturned entrance lip at each of the entrance and exits edges, with downturned lips at each side edge. A settler unit has one tray as an upper tray and another tray as a lower tray, the two trays being mounted parallel and at a low-angle to define a dirty flow entrance, a clean flow exit, and a pocket between the upturned entrance lip and the upturned exit lip for receiving and capturing settled-particles from the dirty flow while cleaner flow flows from the entrance to the exit. A sludge exit is at each side of the trays for permitting the captured settled-particles to exit the pocket.
