Definitions
- the invention relates to a method for processing a product by means of a phase separation according to the preamble of claim 1.
- DE 10 2005 021 331 A1 shows a separating separator.
- DE 10 2005 021 331 A1 shows a separating separator.
- the derivation of a heavier liquid phase via an outlet which is associated with a throttle device and only the derivation of a lighter liquid phase by means of a paring disc.
- WO 94/06 565 A1 discloses a separating separator in which the lighter liquid phase takes place by means of a paring disc and the other heavy liquid phase by means of a discharge device by means of tubes adjustable at an angle to the radial, which are adjusted once to a desired radius, so that In operation, the derivation of this phase is always carried out, but such that only a portion of the tube is immersed in the heavy phase, which should keep the friction low.
- DE 697 12 569 T2 discloses a Trennseparator, in which the lighter liquid phase by means of a baffle plate and the other heavy liquid phase by means of an outlet element which is pressed with a drive device to varying locations of a free liquid surface, so that during operation also always the derivative of this Phase takes place, as possible, the immersion depth should be kept constant in this phase to reduce energy consumption.
- the invention has the object to solve this problem in a simple manner.
- the invention solves this problem by the subject matter of claim 1, that is, by simple means and with a very simple method in that the heavier liquid phase HP and the solid phase are discharged only discontinuously, whereas the lighter liquid phase LP is continuously passed out of the drum.
- a sufficient amount of the heavier phase can always accumulate farther out in the drum until it is possible to remove that amount of heavier phase from the drum.
- the drain is interrupted for a period of time until a sufficient amount of heavy liquid phase has accumulated again outside the drum to drain it from the drum.
- the solid phase can likewise be ejected discontinuously from the drum, preferably by means of solids discharge openings displaceable by a piston slide, preferably independently of the time when the heavy liquid phase is emptied.
- the process according to the invention can be used particularly advantageously in the processing of vegetable or animal oils and fats, which have only a relatively small proportion of heavy phase, in particular less than 3%.
- FIG. 1 shows a sectional view of a separator drum with a hood, shown schematically
- the rotatable Separatortrommel 1 is set to a rotary spindle 2, which is driven for example directly or via a belt and which is rotatably mounted (not shown here).
- the rotary spindle 2 may be designed conically in its upper peripheral region.
- the separator drum 1 is surrounded by a stationary hood 3 that does not rotate with the drum.
- the advantageous double-conical separator drum 1 has a product feed pipe 4 for a product P to be hurled, to which a distributor 5 adjoins, which is provided with at least one or more outlet openings 6, through which incoming centrifuged material into the interior of the separator drum 1 and at least one Rising channel 7 of the plate package can be passed.
- a supply line through the spindle, for example, from below is also conceivable.
- the construction is chosen such that the outlet openings 6 below a riser channel 7 in a plate package 8 of conically shaped separating plates (not shown).
- a divider plate 9 which has a larger diameter than the plate package 8.
- the solid phase is designated S. It is discontinuously discharged through solids discharge openings 10, which can be opened and closed discontinuously with the aid of a piston valve 1 1.
- the lighter liquid phase LP (light phase) is conducted at an inner radius n_p into a peeling chamber 12 and from there by means of a first peeling member, a peeling disk 13 (also called a gripper), out of the drum.
- the paring disc acts like a pump.
- the peeling disc may e.g. be downstream of the separator in the downstream derivative of a valve (not shown here) for throttling.
- the inlet 14 in the paring disc 13 is located on a fixed diameter, which is not adjustable.
- the heavy phase HP flows around the outer circumference of the divider plate 9 through a discharge channel 15 into a second peeling chamber 15, in which a second peeling element 16 is arranged.
- This peeling member is designed such that its inlet or its inlet opening 17 within the peeling chamber is continuously or discontinuously adjustable (see also Fig. 2), so that at least a first inner radius Ri and an outer radius Ra can be achieved in the drum ,
- the second peeling member 16 is formed as a peeling tube, which is formed in the section of Fig. 1 L-shaped and has a first portion 18, which is radially aligned in the peeling chamber and a second, parallel to The axis of rotation D aligned portion 19, which is guided upward from the rotating system, wherein the
- Section 19 is rotatable about its longitudinal axis on the radius r19.
- a pivoting of the peeling tube 18 about this axis of rotation r19 makes it possible to pivot the inlet 17 between the mentioned inner radius Ri (dashed line position in FIG. 2) and the outer radius Ra (not dashed representation in FIG 2).
- a device for pivoting the peeling tube is arranged outside the separator.
- the pivoting per se can be realized in a variety of ways, such as by means of a gear transmission, a lever mechanism or by means of a hydraulic or pneumatic drive.
- a toothed segment 20 may be formed on the outer pipe diameter, which meshes with a drive gear 21 of a transmission, which is otherwise not shown, to which an electric motor (not shown) is connected upstream.
- the drive and the gear connection to the peeling member can also be realized in other ways.
- the above-described three-phase Trennseparator with the drum 1 with a vertical axis of rotation is suitable for the separation of various fluid mixtures such as for the separation of water from oil.
- Trennseparatoren occur problems with the continuous discharge of the heavier phase, especially if only very small volume flows of this phase are to be processed or if the proportion of the heavier phase relative to the lighter phase is very low, for example, if the proportion of heavier phase on the incoming product less than 3%, preferably less than 1%, most preferably 0.5%.
- This problem is solved by means of the illustrated Trennseparators in that the heavier liquid phase Hp is discharged only discontinuously.
- the adjustable second peeling element 16 is adjusted to such a small radius Ri or, if it is not already set up on this inner radius, that it does not dive into the heavy phase HP during operation.
- the heavy phase - such as water in the separation of water and oil - accumulates outside in the drum 1, so that the radius to which the heavier phase, especially the water, extends in the drum 1 from outside to inside goes up.
- the inlet 17 of the peeling member 16 Upon reaching a predetermined inner radius, for example, when the heavier liquid phase HP - especially the water - reaches the inlet 17 of the peeling member 16 (or for example after a predetermined time interval), the inlet 17 of the peeling member 16 in a step ii) on a larger radius Ra (see Figs. 1 and 2) adjusted so that it dips into the heavier liquid phase HP, so that the heavier liquid phase HP is discharged from the drum 1.
- the maximum radius up to which the heavier liquid phase HP extends in the drum 1 further increases radially outward relative to the axis of rotation D. at.
- the inlet 17 is again pivoted to one, preferably the inner radius Ri from step i), so that again according to step i) the discharge of the heavier phase HP is interrupted.
- timing of skimming the heavy phase may also be controlled via timing and may be particularly simple, for example, at fixed intervals.
- the time of skimming by means of a sensing and / or measurement can be carried out (in this respect would be particularly advantageous: a contact pressure gauge, a flow meter, a water sensor in the process).
