Definitions

  • the invention relates to a method for processing a flowable product according to the preamble of claim 1 and a centrifuge, in particular a separator, according to the preamble of claim 9.
  • DE 10 2006 022 156 A1 discloses a method and a device for the treatment of liquids, in which an incoming flowable product is separated in a centrifuge into two liquid phases and a solid phase.
  • the product for example a contaminated lubricating oil
  • the product is separated into two partial streams, which are conducted past a positive or a negative electrode.
  • the particles which are contained in the first partial flow are positively charged and the particles of the second partial flow are negatively charged.
  • both partial streams are combined in a collection tank, whereby the positively charged particles and the negatively charged particles conglomerate to form larger particle dressings due to the mutual electrostatic attraction. These conglomerates are then easier to separate from the liquid in the centrifugal field.
  • SU 5 51 036 discloses a centrifuge which enables electrostatic charging of particles within a non-continuous centrifuge.
  • an electrode is arranged in an inlet chamber on the axis of rotation of the centrifuge. After electrostatic charging of the particles, they are passed on to a drum space in which the particles are deposited in solid collecting pockets. The clarified liquid is then removed from the centrifuge. The solid collecting pockets are embedded in the wall of the centrifuge.
  • continuous operation is not possible with this centrifuge because the collection bags must be emptied at regular intervals.
  • the invention achieves this object by a method having the features of claim 1 and a centrifuge having the features of claim 8.
  • a method for processing a flowable product with a centrifuge in particular a separator with a vertical axis of rotation, with a rotatable centrifuge drum in which a plate package, at least one product outlet and at least one solids discharge opening is arranged, comprises the following steps:
  • the electric field between the plates of the plate package and the remaining part of the centrifuge insulated therefrom is generated by impressing a charge starting from a DC voltage source.
  • step a) the transmission of the positive or negative charge from the outside to a component of the centrifuge can take place, wherein one pole of the DC voltage source Le is contacted with an outer wall of this component and this component consists of electrically conductive material. After charge transfer, this charge is transferred or transferred to the plate package of the centrifuge.
  • the pretreatment of step a) is preferably carried out outside the drum. The pretreatment is also preferably carried out in such a way that the particles are attracted to the charge of the plate package.
  • the pretreatment in step a) can take place according to a first advantageous variant of the invention by an electrostatic charging of the particles, for example outside the centrifuge.
  • the product to be processed is passed past a positively or negatively charged electrode, whereby particles, for example solid particles, are charged to the electrode prior to entry into the centrifuge.
  • This electrode is preferably arranged outside the drum. It is also conceivable, however, to integrate them into the inlet of the drum.
  • the pretreatment in step a) can be carried out according to an alternative variant of the invention but also by adding a ferrofluid, in order to achieve the above-mentioned effect.
  • step d After the particles have been deposited in step d), it is advantageously possible for the electric field to be switched off and / or discharged on the disk package, so that the deposited particles more easily slip off the surface of the disk into the solids.
  • the deposition can be monitored, for example by a probe on a product outlet of the liquid phase or liquid phase. If the proportion of solids exceeds a predetermined value, the deposition on the plate is insufficient. By monitoring the deposition, the process can be adapted to the respective product. Alternatively, the feed can be closed during the polarity reversal or switching off of the electric field.
  • a centrifuge in particular a separator, a centrifuge drum, in particular a continuously operable separator drum with a vertical axis of rotation, in which a disc package is arranged, wherein the centrifuge drum at least one product feed for supplying a product to be processed, a disc pack for phase separation and at least an outlet for draining a liquid phase and a drain for discharging at least one further phase, in particular a liquid phase or a solid phase.
  • the centrifuge also has at least one means for generating an electric charge on the plates of the plate package or in plate columns of the plate package.
  • particles are deposited in the region of a centrifuge, at which the deposition usually takes place without the additional influence of electrostatics.
  • the deposition rate of these charged particles is improved, and crossing of the already deposited particles with the product feed stream is prevented.
  • a suitable DC voltage source can be used, wherein the height of the generated voltage is preferably adjustable.
  • a positive pole is present at one point of the separator and a negative pole at another point of the separator.
  • One of the poles is conductively connected to the plate package.
  • the disk pack is electrically insulated from the outer wall of the centrifuge drum by a coating or other non-conductive material, so that it can not come to a short circuit due to contact of the two components.
  • a suitable voltage level for such a DC voltage source is in the range between 5000 and 20,000 volts.
  • the means for generating an electric charge on the plates of the plate package is preferably arranged outside the centrifuge drum.
  • a first pole of the DC voltage source can be arranged with positive or negative charge on the outer wall of a pump element of the centrifuge, which is connected to the plate package.
  • the pole only has to be attached to the pump element, further design adjustments of the centrifuge drum are not necessary. This is advantageous, since thus an already existing centrifuge can still be retrofitted.
  • FIG. 1 is a partial sectional view of a separator drum in a hermetically sealed design.
  • a rotatable Separatortrommel 1 with vertical axis of rotation D is set to a rotary spindle 2, which is driven by a direct drive or by a belt drive, not shown here.
  • the rotary spindle 2 is conically shaped along an upper circumferential region and fastened with a fastening means 6 on the drum base 20.
  • a product inlet 4 is adjoined by a product inlet pipe 5 which rotates during operation and which is aligned concentrically with the axis of rotation D.
  • the product P passes into a manifold 7 having manifold bores or fins from which the flowable product is e.g. can emerge in the radial direction in the interior of the separator drum 1. It is also conceivable (not shown here) to direct the product from the distributor into at least one rising channel in the plate package.
  • the incoming product flows into the plate gap between conical plates of a plate package 1 1 spaced apart from one another by axially intermediate spacers.
  • a better separation of solid particles in the disk columns of a Teller package is made possible in the present case by applying the plate package 1 1 with an electric charge. This also means that already deposited particles stick to the underside of the plate.
  • an outer wall 1 8 of the separator drum 1 or an outer wall 1 9 of the pump element 1 2 via a respective electrical line 1 5a and 1 5b connected to a positive and a negative pole of a DC voltage source 14.
  • Another component, such as the actual separator drum 1 is polarized in the opposite direction.
  • the plate package 1 1 is insulated from the inner wall of the separator drum 1, here by one or more non-conductive material layers 1 6, 1 7 above and below the plate package 1 first
  • the distributor 7 is also insulated by an upper material layer 1 7 and a lower material layer 21.
  • drum base 20 may also be insulated from the rotary spindle 2 by an electrically non-conductive material layer 22.
  • the product inlet pipe 5 and the manifold 7 are preferably made of an electrically non-conductive material or have a non-conductive coating, so that preferably already charged before entering the drum parts not settle or unload here already on the components.
  • a pretreatment in the manner of step a) of claim 1. the product is first passed before entering the rotating separator drum to a negative or positive charged electrode of a DC voltage source, so that the solid particles in the product charge electrically.
  • This electrode can also be arranged alternatively in the product feed 4 or in the feed pipe 5.
  • the loading of the solid particles can also be done elsewhere before the entry of the product flow in the plate gap of the plate package 1 1.
  • a suitable voltage level for such a DC voltage source is in the range between 5000 and 20,000 volts.
  • the product supply pipe 5 and the distributor 7 consist of non-conductive material or are coated with non-conductive material, so that the deposition preferably takes place only in the disk package.
  • the product After the product has entered the drum 1, it enters the plate column of the plate pack 1 1.
  • the charge of the particles of the product is opposite to the charge of the plates, so that the plate exerts an electrostatic attraction on the charged particles, which collect increasingly on the plates.
  • the plate column therefore continue to grow over time.
  • the plate package increases with time. It is therefore advantageous if this is suitably monitored during operation (for example based on the inflow quantity or the outflow quantity) and if, depending on the monitoring or periodically at predetermined time intervals, the plate package is reversed and, if appropriate, the drum is emptied rinse out the attached particles.
  • the DC voltage source is preferably on connected the control system of the centrifuge (not shown here).
  • FIG. 1 shows a separator which allows a solid-liquid separation.
  • the method can also be applied analogously to three-phase separators.
  • the deposition of solids on a charged plate package in other designs, e.g. be used with hanging drums.
  • the inventive method and the centrifuge are suitable for a wide variety of products, but in particular for the purification of a contaminated oil. It should also be noted that although the embodiment is preferred as a hermetically sealed machine with rotating inlet pipe and an instructive pump element, in which the product is pumped through the machine, it is not mandatory.
