Definitions
- the invention relates to a method according to the preamble of claim 1.
- hydrocyclones are well suited to removing heavy parts by centrifugal forces or concentrate light parts in fiber suspensions and by using one to lead the intended discharge opening out of the hydrocyclone.
- the operational safety especially the freedom from clogging of such hydrocyclones particularly important. Blockages can occur if the contaminants, e.g. in the area of the discharge opening provided for them, so collect and concentrate that there is a blockage. In many cases, a A compromise can be found between operational safety, i.e.
- a known way to To reduce the risk of constipation on heavy-duty hydrocyclones is that a dilution liquid is supplied.
- a water supply leads into Edge area of the hydrocyclone e.g. through slots in the circumferential direction in the Cyclone wall.
- the dilution fluid then swirls the outer layers and must penetrate the heavy dirt already concentrated in it, resulting in a Backwashing heavy parts in the accept stream can result.
- the invention is based on the object of a method for applying To create contaminants from hydrocyclones, with which both a reliable Removal of the contaminants is possible, as well as a good separation effect.
- the dilution liquid is therefore not introduced into the Edge of the hydrocyclone, where blockage is expected, but in the center, with axial Direction, and thus mainly in the core flow.
- the dilution liquid With a sufficiently large one Inflow velocity the dilution liquid reaches the conical area of the separating room and mixes through the effect of the ruling ones Gradually shear flow with the surrounding fiber suspension.
- the kind of Dilution leads to a gentle backwashing of the fibers in the material without that the same thing happens with already concentrated heavy parts, since these are on the wall and are not affected by the dilution water addition. Without the measures according to the invention, some of those that have already been concentrated would be concentrated Heavy parts whirled up and get into the middle of the hydrocyclone. From there then discharged with the accepted material.
- the hydrocyclone 1 shows a hydrocyclone according to the invention, roughly schematically an inlet 2 for the paper fiber-containing suspension S and an accept material outlet 3 for the cleaned suspension, i.e. the accepted substance A.
- the suspension S to be cleaned becomes set in rotation and enters the separating part 6 with a separating cone 1, in which the speed of rotation usually increases again. This will the contained heavy parts ST concentrated on the inner wall of the separating cone 1 and go down into the reject discharge device 17.
- the designated addition point 5 has the narrowest Position 4 of the separating cone 1 is the distance a, which is preferably in axial Seen direction, is at most a few millimeters.
- this can Distance a up to 30% of the length L of the hydrocyclone.
- Another sensible one The requirement is that the axial distance to the inlet 2 be kept as large as possible e.g. at least 70% of the length L of the hydrocyclone.
- the heavy parts ST fall, after they have passed the narrowest point 4 of the separating cone 1, into the Discharge chamber 8 from which it, e.g. via a discharge device 17, as reject R be removed.
- This discharge can take place continuously or intermittently.
- the dilution liquid W is replaced by a simple one vertical inlet pipe 9 is added, which is an axial and at the addition point 5 against the direction of discharge of the contaminants ST has an opening.
- Circumferential component Vu (see FIG. 5) is so low compared to the axial speed Vax to hold that the angle ⁇ between the resultant of the two vectors and the Axis does not exceed 30 °. Overall, with this type of Dilution water addition to a much larger volume distributed and is therefore less harmful to the separation effect.
- the liquid W is particularly advantageously at a certain axial position in the Hydrocyclone entered. Then there is only one opening at the addition point 5. It may be possible to adjust their position in the axial direction.
- FIG. 2 shows a variant for carrying out the method Dilution liquid W via a curved inlet pipe 9 directly in the middle of the entered reject tube 11 below the separating cone 1. It is here the addition point 5 selected so that it is below the narrowest point 4, what but not necessarily so.
- FIG. 3 shows a further possibility for carrying out the method.
- the Dilution liquid W first placed in a flow insert 16 ', in the Inside there is a central displacement body 12, so that an annular Flow cross section arises.
- the ring-shaped jet easily penetrates the one above part of the separating cone. It is also indicated here by arrows, like that Heavy parts ST slide down into the discharge chamber 8 near the wall. she can do this without going through the flow of the dilution liquid into the core flow of the Hydrocyclones to be flushed.
- FIG. 4 shows an axial inflow of the Dilution liquid W through the central inlet pipe 9. It opens inside the Flow insert 16 '' via an injector 13 into a central tube 14 Parts of the suspension are sucked out of the hydrocyclone and in the middle again be added, which serves the stable operation and the fiber loss minimized.
- FIG. 6 A hydrocyclone similar to that in FIG. 1 is shown in a perspective view in FIG. 6 shown. More constructive details are visible, but also these Drawing is still greatly simplified.
- FIG. 7 essentially shows the lower part of FIG. 6 in an enlarged form.
- Man This makes it easier to recognize that the inlet pipe 9 is screwed in exactly in the middle and in one circular opening opens here above the narrowest point 4. It's easy too mount and can be adjusted axially. With the help of the axial adjustment is one better adjustment of the hydrocyclone to the existing conditions possible.
- the discharge chamber 8 of FIG. 8 has a slightly eccentrically inserted one Inlet pipe 9, but this remains in the radially inner region of the hydrocyclone.
- the Outlet cross-section of the inlet pipe 9 holds one from the wall of the hydrocyclone Distance b a, which is at least 10% of the inside diameter of the hydrocyclone on it Digit is. It must be guaranteed that the already concentrated Heavy parts can no longer be washed in by the dilution liquid.
- the Eccentricity can bring advantages in special cases, e.g. if the hydrocyclone is operated horizontally. It can also be made adjustable.
- the flow inserts shown should only show the principle. More usable Flow applications are conceivable. In particular, their dimensions can be determined by Invoice and simple tests tailored to the respective purpose become.
