Definitions
- the invention relates to a mixing element for a flange transition in one Pipe according to the preamble of claim 1 and a pipe with such a mixing element.
- a flange mixer is known for its installation only one pair of flanges is needed.
- This flange mixer is formed like a dazzle. Its mixed structure includes two mirror symmetric surface areas, between which a Throughflow is located; this has a central bottleneck and two extended lenticular zones across the bottleneck. The Surfaces can lie on two levels that are inclined against each other are and their intersection - projected perpendicular to a pipe cross-section - forms a midline of the bottleneck. In one the central bottleneck flowing fluid caused due to the glare of the Bottleneck vortex, on the one hand a mixing effect on dosed additives on the other hand cause a relatively large pressure drop. by virtue of the mirror symmetry is a small mass transfer between the through the intersection line and midline given tube halves.
- Flange mixers have arranged opposite to those in pipe sections static mixers have the advantage that they have a small volume. To certain calculation rules apply thanks to the small volume not as a pressure vessel and therefore do not need for approval elaborate examination procedure.
- a disadvantage is that the flange mixer consists only of a mixing element and that he thus a limited Has mixed effect.
- the object of the invention is an alternative to the known Flange mixer to create an improved mixing effect has low pressure loss.
- This object is achieved by that in claim 1 defined mixing element, which is a flange mixer, solved.
- the additive be fed through a variety of access points, so that the Mixing effect of the flange mixer, which consists only of a mixing element exists, can suffice.
- the mixing element is for a flange transition in a pipeline provided and is mounted between two flanges of the pipeline. It includes a mixed-structure, through one or two wings formed within a ring. Two inclined planes are definable, whereby on the one level the one wing or on both Layers the two wings are arranged. The two levels intersect on a crossing axis. Closed partial surfaces as well as open ones Faces of the wings form a surface pattern that is relative to the Crossing axis is formed asymmetrically.
- asymmetric Form is a fluid flowing through the pipeline so deflected that Partial flows from a pipe half through partial surfaces of a plane in the other half pipe are deflected and there largely not diverted partial flows meet, and this also vice versa with respect to other level applies, if on this a second, structural elements exhibiting wing exists.
- Fig. 1 shows a detail of a longitudinal section through a pipe 1 at the location of a flange 10, on which a ring 20 between Flanges 11 and 12 is inserted.
- a Structure 25 arranged for which in the drawing only their location 25 ' is shown in Fig. 2 in a schematic form 25 "as a Surface pattern is shown.
- the structure 25 acts as a static mixer a fluid 9 indicated with arrows 90, which is the pipeline 1 flows through.
- the structure 25 can be made of a sheet, for example Punching and folding, manufacture. That from the ring 20 and the mixed effective structure 25 composite mixing element 2 is on Flange transition 10 can be mounted; it is by means not shown screws the flanges 11 and 12 attached.
- the structure 25 is each with a wing 25a or 25b arranged on two mutually inclined planes 21 and 22, the to intersect on a crossing axis 23.
- the crossing axis 23 is arranged downstream of the ring 20.
- the wings 25a and 25b may be configured to have parts of them over the Junction axis 23 on the side of the other wing 25b and 25a protrude (see Fig. 12).
- the use of a separate ring 20 is advantageous but not necessary.
- the mixed structure 25 may, if appropriate, between the flanges 11 and 12 are clamped.
- FIG. 4 Closed part surfaces and open surface pieces of the structure 25 form a surface pattern 5, which in a specific embodiment with closed part surfaces 52, 51 ', 55, 56 and open surface portions 51, 520, 521, 522 is shown in Fig. 4, wherein the surface pattern 5 in the Image plane is unfolded.
- Figures 2 and 3 is a surface pattern shown as the reference system 4 for a characterization of the Surface pattern 5 is introduced.
- the reference system 4 in Fig. 3 is the plane Folding out of the surface pattern 25 "shown in FIG. 2 as an oblique image.
- the two wings 25a and 25b are largely complementary antisymmetric form in the following sense: 1.) It is a reference system 4 definable by boundary lines 40, 40 ', 40 ", 43 of reference surfaces 41, 41', 42, 42 'is formed and with respect to the crossing axis 23 or Symmetryeachse 43 is mirror-symmetrical; 2.) the partial surfaces 52, 51 ', 55, 56 and patches 51, 520, 521, 522 of the surface pattern 5 and the Reference surfaces 41, 41 ', 42, 42' of the reference system 4 cover common Areas 52, 51 ', 51, 520, 521, 522 starting smaller than the covering ones Surfaces 41, 41 ', 42, 42' or the same size.
- the special antisymmetry of the mixed structure 25 has now the According to the invention aimed effect, which is explained with reference to FIG. 2:
- With the arrows 9a and 9b is the flow of the to specified mixing fluid.
- the arrows 9a are in the Main flow direction (arrow 90 in Fig. 1) oriented.
- the Arrows 9b each directed against an arrow 9a. Express these relationships This is due to the fact that a fluid exchange between the areas of the two Wings 25a and 25b takes place, so that a mixing over the entire cross-section of the pipe 1 results.
- the inventive mixing element 2 can be more general Characterize as follows:
- the surface pattern 5 of the mixed effective Structure 25 is asymmetrical with respect to the crossing axis 23. Due to the asymmetric shape is a pipe 1 flowing through Fluid 9 can be deflected such that partial flows 9 b, which by partial surfaces of the one Wing 25a be redirected to the side of the other wing 25b, there to encounter largely undirected sub-streams 9a. this is also valid inversely with respect to deflected part streams 9b of the other wing 25b.
- FIGS. 5 to 8 Two further embodiments of the invention are shown in FIGS. 5 to 8 shown. While in an example, the number of open patches on one wing 25a is one and on the other wing 25b is two, is in the other example, this number two or three. In these examples The surface patterns 5 differ relatively strongly from the pattern of Reference system 4.
- the surface pattern 5 according to FIG. 5 may be the same Reference system as in the first example Fig. 3 are assigned.
- Fig. 6 shows a superposition of the surface pattern 5 and the reference system. 4 Common areas of this overlay, which are smaller by a maximum of 30% the covering surface pieces 51, 521, 522 or partial surfaces 51 ', 52 of the Surface pattern are 5, are the closed partial surface 72 and the open partial surface 71 on the wing 25a and the closed Partial surfaces 71 'and the open partial surfaces 721, 722 on the wing 25a.
- FIG. 8 The other mixed structure 5 with something more complicated Surface pattern 5 is shown in FIG.
- a correspondingly more complicated reference system 4 namely that of Fig. 8, based.
- An overlay of the pattern 5 of FIG. 7 with the reference system of FIG. 8 leads - analogous to the overlay in Fig. 6 - to common areas, for which again a complementary one Antisymmetry exists. On an explicit implementation of this overlay is waived.
- the mixing element 2 according to the invention should lead to a mixing result, which is associated with the smallest possible pressure loss. Therefore, the open patches 25a and 25b of the wings overall not material be smaller than the free cross section of the pipe 1. This condition is fulfilled when said open patches total at least have the same surface area as the closed part surfaces and when the inclination of the planes 21 and 22 is relatively large, so that of at the crossing axis 23 included angle 120 ° or smaller is.
- the flange mixer 2 may be in a suitable training in the Piping 1 installed and removed, without causing a disassembly Part of the pipeline 1 is required. This requires that the Wings 25a and 25b largely in the area between the two End sections 13, 14 of the ring 20 (see Fig. 1) are arranged.
- For the surface pattern 5 of the mixed structure 25 can be a Mirror symmetry with respect to an axis 44 (see Fig. 3 or 8), the is perpendicular to the crossing axis 23, are provided.
- the inventive mixing element 2 is well suited to an additive the flange 10 to feed into the pipe 1.
- Fig. 9 are Feed points for an additive 95 shown that integrates into the ring 20 are. They are made uniform by a plurality or variety of arranged as well as equal outlet openings 31 formed.
- the Additive 95 is conveyed via a feed pipe 30 into an annular groove 3 ', from which it via the outlet openings 31 in the effective range of dash-dotted lines 25 'indicated mixer structure 25 passes.
- supply pipes 30 for several additives or other admixing fluids should be provided.
- Outlet openings 31 can also enter an annular gap or radially inwards leading grooves in the ring pieces 6 and 6 ', the ring 20 or a inserted seal (not shown) are milled.
- Feed points 30 'for admixing fluid may also upstream the mixing element are arranged, as illustrated in Fig. 10. about a nozzle 31 ', a fluid is fed in front of the mixing element 2.
- a diaphragm 8 To the fluid flow of the pipe 1 in the region of the flange 2 more swirling, can - see Fig. 11 - with a diaphragm 8, the is inserted together with the mixer structure 25 at the flange 10, in the flow 91 additional vortex 92 behind the aperture 80th be generated.
- the diaphragm 8 can also be part of the mix-effective structure 25 be; the structure 25 may be formed on the periphery so as to be Ring aperture works.
- Fig. 12 shows a further mixed effective structure 25.
- This consists of a closed ring 6 placed between the pipe flanges 11, 12 ( Figure 1) can be inserted, a first wing 25a, which consists of a middle Footbridge is formed, and a second wing 25b, consisting of two lateral Webs 25b 'and 25b.
- the wings 25a and 25b are like this formed that parts of them on the crossing axis 23 on the side protrude the other wing 25b and 25a.
- the middle bridge or the both lateral webs may be missing, so the mixed-effect structure 25 has only one wing 25a.
- a mixing element 2, which is one such reduced structure 25, is also an inventive Mixing element.
- An example of such a structure 25, the only one wing has, is shown in Fig. 13; it lacks compared with the embodiment of Fig. 12 of the wings with the lateral webs 25b 'and 25b ".
- the mixed structure 25 may be made of flexible material, for example be made of thin spring steel or plastic. at different throughput so bend the webs differently; of the Flow resistance thus increases less with increasing throughput fast, as if the bars were rigid.
- the mixing elements described above can be modified so that Parts of one or both wings 25a, 25b of the mixed structure 25 from the wing associated with the plane 21, 22 are bent out. So can in the example of Fig. 12, the two lateral webs 25b 'and 25b "to be bent out of the plane 22 different angles.
