Definitions

  • the present invention relates to an improved apparatus for the centrifugal separation of at least two liquid phases and a rigid sedimentary phase making up a mixture, this mixture possibly being constituted, for example, by crude olive oil.
  • the type of apparatus to which the improvements of the invention are applied may be that which is the subject of DTAS 1,103,854.
  • This type of device comprises, around a shower for distributing the mixture to be treated, a rotating enclosure the peripheral wall of which is closed by a coronal bottom and which is coupled to a first device for driving in rotation.
  • This enclosure is integral with an annular partition which plunges into the mixture beyond the phase interface thereof, separates a first chamber containing only the heavy phase, from a second chamber containing the light phase which "floats" the heavy phase, and however spares a peripheral annular passage for the transfer of this heavy phase from the second chamber to the first.
  • the enclosure also has separate thresholds for the discharge of the phases and cooperates with a helical conveyor of the sediments.
  • the conveyor is coupled to a second rotary drive device via a plate which plunges into the mixture beyond the aforementioned interface and separates the second chamber from a cavity with which it nevertheless communicates with the periphery by this conveyor for the transfer of sediments through the heavy phase. Finally, the conveyor is also secured to a centrifuge device plunging at least into the light phase of the second chamber.
  • This type of known device does not give any satisfaction to the user because the light phase ex treats - the oil - is not pure and still contains, in a significant proportion, the heavy phase - water in particular - as well as a little sediment which affects its clarity, while another proportion of the light phase is lost by escaping with the extracted heavy phase.
  • the object of the invention is therefore to remedy this major drawback, by perfecting this type of device in such a way that the light phase is extracted from the mixture, perfectly pure and in full, that is to say without loss, and that it is the same for the heavy phase.
  • the Applicant has found that the centrifuge device of the second chamber containing the light phase which "floats" on the heavy phase does not entail this light phase at a strictly constant angular speed and that this centrifuge device only fills 'a limited part of this second bedroom.
  • the Applicant has also found that the first chamber is free from a centrifuge device capable of driving the heavy phase at constant angular speed.
  • the Applicant has finally found that there is nothing to prevent sediments from being entrained by the heavy phase towards the first chamber and blocking the passage connecting the two chambers.
  • the. transition zone between the two types of flow is extremely narrow; thus, a few millimeters from the centrifuge device - when the latter exists and truly drives the constant mass of mixture in which it is immersed at constant angular speed - said mixture flows in an irrotational vortex; in other words, while, in the intervention zone of the centrifuge device, the phases of the mixture tend to separate, outside of this centrifuge device, the phases tend to remain mixed; in addition, it is important to note that the stable phenomenon is that of the vortex and that it tends to propagate within the centrifuge device while causing a remixing of the phases as and when they are separated by these measures.
  • Another cause of the ineffectiveness of the known apparatus is that the transfer of the heavy phase between the two chambers is not ensured under the best conditions and generates disturbances relative to the flows of the phases in the two chambers, flows which should be at constant angular speed.
  • a first centrifuge device is housed in the first chamber, is integral with the walls of the latter and has, whether it is of the type with radial or inclined blades, with conical plates, with slotted and edged plates or the like, surfaces extend throughout the treated volume, across their circular movement, to transmit the rotation of the first drive device to the heavy phase at a rigorously constant angular speed throughout its mass and at all points;
  • the second centrifuge device housed in the second chamber is integral with the plate, extends along this chamber to reach as close as possible to the separating partition, the discharge threshold of the light phase and the annular passage of the heavy phase and present, whether it is of the type with radial or inclined blades, with conical plates, with slotted and edged plates or the like, surfaces extend throughout the treated volume, across their circular scrolling, to transmit rotation of the second drive device at least in the light phase, at an angular speed which is rigorously constant throughout its mass and at all points, thus opposing any degeneration, by natural tendency, of this type of flow at
  • the regulating device for the combined control of the two rotary drive devices cooperates with a control member sensitive to the specific masses or to the clarities of the two phases. liquids measured at the spill threshold.
  • the extreme turn of the conveyor located near the partition which separates the chambers is perforated to establish additional direct communication between these two chambers, this perforation making it possible to avoid pumping back from the light phase to the heavy phase.
  • the end of the conveyor located near the partition which separates the chambers is integral with at least one scraper element extending near the peripheral wall and directed in the annular passage to avoid any accumulation of sediment in the first chamber to heavy phase, this scraping element forming with an enclosure generator an angle between 0 and 45 °.
  • a labyrinth seal is interposed between the partition (which separates the two chambers) and a continuous central ring of the conveyor.
  • the discharge thresholds are adjustable tubes carried by the peripheral wall and extending from the center towards the periphery to open out of the enclosure and flush with the free surfaces of the heavy and light phases respectively in the chambers which contain them; the partition is stepped and has a skirt connecting a central flank to a peripheral flank; the tubes taking the light phase pass through the skirt by pressing against the peripheral flank in the first heavy phase chamber and against the central flank in the second light phase chamber at this location.
  • the apparatus comprises a rotating enclosure 1 constituted by a cylindrical peripheral wall 2 extended by a frustoconical wall 3 and closed by a coronal bottom 4 secured to a hub 5 also frustoconical which penetrates inside.
  • the conveyor 7 is fixed around the device 17 and is therefore driven at the same speed of rotation as the latter by the pulley 14, speed which is different from that of the enclosure 1 driven by the pulley 11.
  • a separating partition 20 is fixed against a shoulder of the hub 5 and extends towards the wall 2 of the enclosure; the beveled peripheral edge 21 of this partition defines with said wall an annular passage 22 which establishes permanent communication between two chambers 23 and 24 separated by said partition.
  • the chamber 23, of annular shape, is delimited by the wall 2, the bottom 4 and the partition 20; it is intended to contain only the heavy liquid phase which, in the established centrifugation regime, reaches the cylindrical level 25 concentric with the axis of rotation 6.
  • the chamber 24, also of annular shape, is delimited by the wall 2, the partition 20 and the plate 15; it is intended to receive the mixture to be treated and to contain, in particular in the central zone, the light phase which, at the same speed as above, reaches the cylindrical level 26 also concentric with the axis of rotation 6 but closer to that that level 25 of the heavy phase.
  • the interface between the heavy phase and the light phase is located at the cylindrical level 27 only in the chamber 24, the plate 15 opposing any crossing and flow of the light phase towards the cavity 28 for discharging rigid sediments.
  • the mixture to be treated is distributed by a central nozzle 29 in a tube 30 coaxially integral with the plate 15 and extending in the cavity 28; this mixture reaches the plate 16 which projects it radially into the centrifuge device 17, 18 or 19.
  • the heavy phase is evacuated from the chamber 23 by an overflow threshold; preferably this threshold is constituted by at least one radial tube 31 (six in the example shown in Fig..3) carried by the peripheral wall 2, a threaded connection 23 making it possible to adjust its protrusion and thus the level of its mouth which determines then that of the free surface 25 of the heavy phase in said chamber 23.
  • an overflow threshold preferably this threshold is constituted by at least one radial tube 31 (six in the example shown in Fig..3) carried by the peripheral wall 2, a threaded connection 23 making it possible to adjust its protrusion and thus the level of its mouth which determines then that of the free surface 25 of the heavy phase in said chamber 23.
  • the light phase is evacuated from the chamber 24 by an overflow threshold of the same type; this threshold is then constituted by at least one radial tube 33 carried by the peripheral wall 2, a threaded connection 34 also making it possible to adjust its protrusion and thus the level of its mouth which then determines that of the free surface 26 of the light phase in said chamber 24.
  • the partition 20 is stepped and has a skirt 35 connecting a central flank 36 which is fixed to the hub 5, to a peripheral flank 37 which delimits the passage 22 actually.
  • the tubes 33 intended to take the light phase in the chamber 24 extend in the chamber 23 against the peripheral flank 37, pass through the skirt 35 and open very close to the latter in said chamber 24 against the flank central 36; these tubes therefore open flush with the surface in the chamber 24.
  • the centrifuge device 17 (or 18 or 19) can occupy the entire treatment volume of said chamber 24; it is integral, by one of its ends, with the plate 15 and, by its periphery, with the conveyor; it extends along the chamber 24 and ends, at its other end, as close as possible to the stepped partition 20; as a result, this last end of the centrifuge device is conformally complementary to the stepped profile of the partition 20 provided with the tubes 33, leaving only a minimum clearance which is of the order of 1 or 2 mm, this clearance being necessary since the centrifuge device 17 does not rotate at the same angular speed as the enclosure 1 and the partition 20 consequently.
  • the light and heavy phases flow through the tubes 31 and 33 respectively and spring outside where they are collected by fixed annular gutters.
  • the centrifuge device 17 is constituted by a plurality of blades 38 extending longitudinally, that is to say parallel to the axis of rotation 6. These blades are arranged side by side (Fig. 2) and are inclined, with respect to the radial directions, at an angle "a".
  • the angle "a” can be understood, depending on the nature and composition of the mixture, the intensity of the centrifugal field ... between 20 and 90 °; however, in the example shown concerning the purification of olive oil, this angle is substantially equal to 40 °.
  • the blades 38 delimit two by two of the passages 39 in which the heavy particles 40 precipitate centrifugally, on one face of the blade and accumulate to form a film which flows in the direction of the arrow F .1 along the slope towards the periphery to move towards the chamber 23, while the light particles 41 precipitate, in a centripetal manner, on the opposite face of blade and accumulate to form another film which flows in the direction of arrow F.2 along the slope towards the center to accumulate in chamber 24.
  • the blades 38 are rigidly held in place to form a rotor capable of supporting the centrifugal field. To this end, the blades are welded at one of their ends to the plates 15, 16 and, near their other end, on a central ring 42 and a peripheral ring 43 connected together by spokes 44 suitably distributed; it is obvious that intermediate holding wheels similar to the previous one, 42 to 44, can be provided if the length of the blades 38 is too great.
  • the heavy phase which remains in the cavity 28 to the cylindrical level 45 (FIGS. 1 and 4) to be driven at substantially the same speed of rotation as the heavy phase in the chamber 25. Consequently, the cavity 20 is free of liquid animation means; however, the conveyor 7 must be maintained and for this purpose, its turns are connected together by longitudinal bars 46 directly coupled to the plate 15 and, via arms 47 and 48, to the tube 30 thereof. Under these conditions, if the enclosure 1 rotates faster than the conveyor 7, the total thickness of the phases treated in the chamber 24 can be increased while maintaining the heavy phase at level 45 in the cavity 28.
  • the chamber 23 contains a centrifuge device 49 driven by the pulley 11 at the same speed of rotation as the enclosure 1 and, consequently, at a speed different from that of the above-mentioned centrifuge device 17 which is driven by the pulley 14.
  • the device 49 comprises, in the example shown (Fig. 3, 5 and 6) six blades 50 extending in radial planes between the threshold tubes 31 and made integral, in particular by welding, of the wall 2 and from the bottom 4 by marrying the stepped shape of the partition 20; so as not to disturb the flow of the heavy phase, from the chamber 24 towards the chamber 23, the blades 50 have a notch 51 opposite the annular passage 22.
  • the pulleys 11 and 14 or other coupling means must be rotated at different angular speeds which are those retained for centrifuge devices 17 and 49. These centrifuge devices rigorously transmit said speeds to the liquid masses contained in the chambers 24 and 23 so that said masses rotate as a unit. As already indicated, the ratio of these rotational speeds must be controlled and regulated with extreme precision.
  • the driving pulleys 11 and 14 or other coupling means are connected by two independent transmissions Tl and T.2 to the two outputs of a variable speed drive V driven by a motor M.
  • the treated mixture is composed of liquid phases whose specific masses are not absolutely constant, it suffices to modify the ratio of the rotational speeds of the pulleys 11 and 14 to precisely stabilize the interface of the light and heavy phases in the chamber 24, at level 27 depending on the levels 25 and 26 to which the threshold tubes 33 and 31 are adjusted.
  • the mixture can consist of crude olive oil and it is known that the specific gravity of the purified oil can vary, depending on the origin of the olives and many other parameters elsewhere.
  • the significant quantity can be the specific mass of the phases flowing through the threshold tubes considered or else the clarities of these phases or others.
  • sensor-comparators C.5 and C.6 of these quantities are connected to the threshold tubes 33 and 31, for example and connected by means of slaving A.1 and A.2 to the aforementioned regulating device R.
  • the conveyor 7 cannot evacuate them towards the mouth of the conical wall 3. It is then necessary to avoid any harmful accumulation, to eliminate them as they appear against the cylindrical wall 2.
  • the latter has at least one calibrated orifice 52 which opens into the chamber 24 near the stepped partition 20 and channels these sediments mixed with heavy phase outwards so that they squirt in a fixed annular drain.
  • the orifice (s) 52 are scraped by the helical conveyor 7 to oppose any clogging.
  • a nozzle 53 fixed in the frame 8 and suitably supplied under low pressure emerges opposite an annular gutter 54 secured to the bottom 4 of the rotating enclosure 1, this gutter communicating with the chamber 23 through at least one opening 55.
  • the first turn 56 delimits openings 58 sufficiently close to one another to annihilate the fluctuations in the flow of the heavy phase from one chamber to the other.
  • the first turn 57 is constituted by two threads 59 and 60 extending respectively, in the peripheral part and in the central part of the conveyor, these threads being kept apart from one another by spacers 61 delimiting between them windows having the same functions as the aforementioned openings 58.
  • a flat ring 62 is fixed, by welding for example, to the rotor 17 at its end near the first turn 56 or 57.
  • This ring supports, by means of a foot 63, at least one scraper element 64 extending as close as possible to the cylindrical wall 2 of the enclosure, from said first turn 56 or 57 and as far as the access passage 22.
  • two elements scraping are planned, but it is obvious that there may be more.
  • the scraping elements 64 extend along the generatrices of the wall 2; on the other hand, according to the second embodiment (Fig. 8), said scraping elements form with the above generators an angle b which is between 0 and 45 °.
  • Figs. 5 to 8 clearly show that a labyrinth seal 65 is interposed between the ring 62 and the stepped partition 20 to prevent any disturbance from propagating from the passage 20 and from the first turn 56 of the conveyor towards the chamber 24 and / or room 23.
  • the centrifuge rotor 18 is constituted by a stack of conical plates 66 connected together by longitudinal members 67 and 68 suitably distributed over their central and peripheral edges respectively. This rotor is fixed on the drive plates 15 and 16 coupled to the drive pulley 14 as well as in the conveyor 7 and, if its rigidity is not sufficient, an extreme holding wheel 42 to 44 and possibly intermediate wheels can be planned.
  • the taper of these plates 66 is between 70 and 100 ° and preferably equal to 80 °, in order to trap and channel the heavy and light particles with the same phase separation result as in the previous embodiment.
  • Said plates also have protruding, on one of their faces, bars 70 or 71, which are located, when the rotor is formed, in the conical tubular chimneys 72 separated by these plates and through which the phases circulate . These bars make it possible to transmit to said phases the rotation at constant angular speed.
  • the bars 70 extend along the generatrices of the plates, in radial planes.
  • the bars 71 are inclined relative to said radial planes.
  • the centrifuge rotor 19 is constituted by a stack of substantially flat coronal discs 73; these are interconnected by internal side members 74 and by a perforated grid 75 or a peripheral cage on which the conveyor 7 is fixed.
  • This rotor 19 possibly reinforced by at least one holding wheel 42 to 44, is fixed to the drive plates 15 and 16 coupled to the drive pulley 14.
  • Each plate 73 delimits a plurality of trapezoidal windows 76 distributed equianglely and separated from each other by screens 77 formed by the solid parts of the plate itself. It is important to note that the plates are angularly offset from each other.
  • each window or slot is delimited, on one side, by a clear edge 78 and, on the other side, by a flange 79 protruding into the intermediate spaces 80.
  • the flanges 79 channel the heavy phase towards the periphery and participate very effectively in driving the rotating phases at constant angular speed.
  • These lateral flanges 79 are radial in the example shown, but they can also be inclined relative to the radial directions at an angle at most equal to 40 °; in addition, they can be extended by a marginal edge 80.
  • centrifuge device 49 is shaped like the centrifuge devices 17, 18 or 19.
  • the method and the apparatus for its implementation are applicable in particular to the extraction of animal and vegetable fatty substances, to the extraction of essential oils, to the production of defatted animal proteins, to the recovery of polymers in mixed solvent medium -water, the extraction of antibiotics, metallurgical refining by selective solvents, the desalination of sea water by the solvent process, the treatment of waste water, etc ...
