Definitions

  • the invention relates to a device for the contact of at least two liquid phases, particularly for extracting one liquid from another liquid, for the absorption of gases in liquids and for permitting a reaction between at least two liquid phases.
  • Suitable devices are for example stirring devices of various constr-uctions driven by individual electromotors, or partitions and plates in various combinations.
  • a device is also known multistage extraction. This device comprises a plurality of adjacent departments through which liquids ow continuously and countercurrently, as disclosed for example in French patent specication No. 1,328,710.
  • Another known device consists of a column with sieve type trays arranged above each other. The individual trays are arranged alternately against each other and a free space is left between the upper edge of each sieve type tray and the internal wall of the column, as disclosed for example in German patent specification No. 1,103,299.
  • Still another known device adapted for mixing and separating comprises a prismatic hollow body with an internal wall against which are arranged rotatably and adjustably impact plates as disclosed in the German patent specification No. 1,159,396.
  • Dispersions produced inthe device are very irregular, as shown, for example by R. E. Treybal in Liquid Extraction, McGraw-Hill, New York, 1963.
  • a more specific object of the invention is a device for the contact of two liquid phases comprising a vertical vessel having the shape of a cylinder with branches for the supply and discharge of liquids.
  • a vertical vessel having the shape of a cylinder with branches for the supply and discharge of liquids.
  • In the vessel there are arranged at least two horizontal plates one above the other. These plates perform the same reciprocating shifting movement in the direction of the longitudinal axis of the vessel and they are provided with holes of two types differing in size.
  • the area of the smallest holes of the larger dimension is at least three times larger than the area of the largest holes of the smaller type, and the number of holes of the smaller type is at least 65 of the total number in the plate.
  • the position of the holes in each plate diifer from the position of the holes in adjacent plates. Two types of holes with a different shape may be provided in each plate.
  • the device for carrying out the invention has plates which, on the side to which flows the dispersed phase are provided with a vertical portion which is for example adjustable and which extends at the utmost to %0 of the distance between adjacent plates.
  • the invention is based on the recognition that in a device of this type it is possible, by means of a reciproeating shifting movement of the plate, to increase the turbulence in the continuous phase and the circulation in drops, and that it is further possible to increase the interphase surface which leads to an increase in eciency.
  • the device in accordance with the invention it is possible to achieve an increased interphase surface without the creation of a signicant part of a too fine dispersion which is easily carried along by the continuous phase.
  • the increased interphase surface is produced by a suitable combination of the reciprocating shifting movement and the size of the holes in the plate which permits to achieve sufficiently large drops to prevent them being carried along by the continuous phase, but also suiciently small to produce a large interphase surface.
  • a device in accordance with the invention permits therefore to operate at large relative phase velocities, for example at a velocity of 2 to 4 cm./sec. and thus to achieve high performances.
  • the vertical partition arranged on the lower or upper edge of the large holes producesduring the intermittently shifting movement of the plate such pressure conditions in its neighbourhood that during part of the oscillation during which the plate moves in the direction opposed to the direction of movement of the dispersed phase, the passage of the dispersed phase through the small holes is increased while its flow Y through the large holes is reduced.
  • the adjustability of direction of stationary partitions It is desirable for the position of the large holes in adjacent plates to be different with respect to the axis of the vessel to prevent direct passage of the continuous phase over the shortest path.
  • PIG. l is an axial section through a vertically arranged cylindrical reactor with two plates;
  • FIGS. 2 and 3 show another type of plate
  • FIG. 4 illustrates a plate with a perpendicular partition having the shape of a cylinder

  • the plate 8 carries a vertical partition 12 on its circumference which rests against the inner wall of the reactor envelope 1. This partition 12 extends below the lower plate surface.
  • the large hole 9 is provided on its lower side with a vertical partition 11 having the shape of a cylindrical envelope.
  • FIG. 5 represents a tray with large and small holes which is provided on its lower side with a resilient packing piece 13 attached by means of a holding ring 14.
  • FIG. 6 shows a tray with a vertical partition 11 with two elongated holes 15 in a direction parallel with the vertical axis of the vessel. Through these holes 15 there pass screws 16 permitting to adjust the position of the partition with respect to the tray. As shown in PIG. 6 the screws are set to their lower position in the holes 1S and in FIG. 7 they are set to the central position in the holes 15.
