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.
- Static mixers which are located in a pipe section of a pipeline are arranged. For the installation of such a pipe section in the pipeline As a rule, there must be two pairs of flanges, two flanges on Pipe section and two assigned flanges on the pipeline. Such static mixers cause small pressure drops when - what in the The rule is the case - do not narrow the cross-section of the pipe section significantly thus cause only a small degree of vertebral detachment, which is high Dissipation of the flow energy results.
- a flange mixer is known for its installation only one pair of flanges is required.
- This flange mixer is trained like an aperture.
- Its mix-effective structure comprises two mirror-symmetrical surface areas, between which there is a Flow opening is located; this has a central bottleneck and two Lenticular zones across the bottleneck.
- the Surface areas can lie on two levels that are inclined towards each other and their crossing line - projected vertically onto a pipe cross-section - forms a midline of the bottleneck.
- a mixing effect on added additives have and on the other hand cause a relatively large pressure drop. Because of Due to the mirror symmetry, there is a low mass exchange between the the intersection line and midline given tube halves.
- Flange mixers have compared to those arranged in pipe sections static mixers have the advantage that they have a small volume. To They apply to certain calculation rules thanks to their small volume not as a pressure vessel and therefore do not require any for approval elaborate examination procedure.
- a disadvantage is that the flange mixer consists of only one mixing element and that it is therefore a limited one Has a mixing effect.
- the object of the invention is to provide an alternative to the known Flange mixer to create an improved mixing effect has low pressure drop.
- This object is achieved by the in claim 1 defined mixing element, which is a flange mixer, solved.
- the additive can be fed in via a large number of access points, so that the Mixing effect of the flange mixer, which consists of only one mixing element exists, can suffice.
- the mixing element is for a flange transition in a pipe provided and can be installed between two flanges of the pipeline. It includes a mix structure by one or two wings is formed within a ring. There are two inclined planes definable, whereby on one level one wing or on both Levels arranged in two wings. The two levels intersect on an intersection axis. Closed partial areas as well as open ones Surfaces of the wings form a surface pattern that is related to the Crossing axis is asymmetrical.
- a fluid flowing through the pipeline can be deflected such that Partial flows from a pipe half through partial surfaces of one level into the other pipe half are redirected and there largely not diverted partial flows encounter, this also vice versa with respect to another level applies if there is a second, structural elements showing wing exists.
- FIG. 1 shows sections of a longitudinal section through a pipeline 1 the location of a flange transition 10 at which a ring 20 between Flanges 11 and 12 is inserted.
- Structure 25 In the interior of the ring 20 is one Structure 25 arranged for which only their location 25 'in the drawing is drawn in and in FIG. 2 in a schematic form 25 "as a Surface pattern is shown.
- Structure 25 acts as a static mixer a fluid 9 indicated by arrows 90 which connects the pipeline 1 flows through.
- the structure 25 can be made of sheet metal, for example Stamping and folding. That from the ring 20 and the Mixing structure 25 composite mixing element 2 is on Flange transition 10 mountable; it is by means of screws, not shown the flanges 11 and 12 attached.
- the structure 25 is each with a wing 25a or 25b on two inclined planes 21 and 22, the intersect on an intersection axis 23.
- the crossing axis 23 is arranged downstream of the ring 20.
- the wings 25a and 25b can be designed so that parts of them over the Intersection axis 23 on the side of the other wing 25b or 25a protrude (see Fig. 12).
- the mix-effective structure 25 can, if configured appropriately, be clamped between the flanges 11 and 12.
- FIG. 2 Form closed partial areas and open area pieces of structure 25 a surface pattern 5, which in a specific embodiment with closed partial areas 52, 51 ', 55, 56 and open area pieces 51, 520, 521, 522 in Fig. 4, wherein the surface pattern 5 in the Image plane is unfolded.
- Figures 2 and 3 is a surface pattern shown that as a reference system 4 for a characterization of Surface pattern 5 is introduced.
- the reference system 4 in Fig. 3 is the plane Unfolding the surface pattern 25 "shown as an oblique image in FIG. 2.
- the two wings 25a and 25b are largely complementary antisymmetric form in the following sense: 1.) It is a reference system 4 definable by the boundary lines 40, 40 ', 40 ", 43 of reference surfaces 41, 41', 42, 42 'and that with respect to the crossing axis 23 or Axis of symmetry 43 is mirror-symmetrical; 2.) the partial surfaces 52, 51 ', 55, 56 and patches 51, 520, 521, 522 of the patch 5 and the Reference surfaces 41, 41 ', 42, 42' of the reference system 4 cover common Areas 52, 51 ', 51, 520, 521, 522 that are smaller than the covering ones Surfaces 41, 41 ', 42, 42' or the same size.
- the closed and open partial surfaces form a with respect to the crossing axis 23 antisymmetric arrangement, for which the following applies: Crossing axis 23 or the axis of symmetry 53 the closed Partial surfaces 52, 51 'to lie on open partial surfaces 51, 520, 521, 522 come and that the reverse also applies. Because of this antisymmetry is a mapping between open and closed areas of the two Given wings.
- the three open ones arranged on the wing 25b Partial surfaces 520, 521, 522 taken together are practically congruent (same shape and area) to the associated closed partial area 52 of the other wing 25a.
- the open partial surface 51 of the wing 25a is congruent to the closed partial surface 51 'of the other wing 25b.
- FIG. 2 The special anti-symmetry of the mix-effective structure 25 now has Effect desired according to the invention, which is explained with reference to FIG. 2: Arrows 9a and 9b schematically show the flow pattern of the mixing fluid specified. In reality there are also eddies for a good mixing effect is essential. These eddies are with the present schematic illustration ignored because another aspect of Mixing effect should be explained.
- the arrows 9a are in the Main flow direction (arrow 90 in Fig. 1) oriented. Give the arrows 9b Partial flows of the fluid through the closed partial areas of the Structure 25 are distracted. Thanks to the complementary antisymmetry, they are Arrows 9b each directed against an arrow 9a. Express these relationships differs in that there is fluid exchange between the areas of the two Wing 25a and 25b takes place, so that a thorough mixing over the whole cross section of the pipeline 1 results.
- the mixing element 2 can be more general Mark as follows:
- the surface pattern 5 of the mix-effective Structure 25 is asymmetrical with respect to the crossing axis 23.
- the asymmetrical shape means that the pipe 1 flows through Fluid 9 can be deflected in such a way that partial flows 9b, which through partial surfaces of the one Wing 25a to the side of the other wing 25b are deflected there encounter largely non-redirected partial streams 9a. this is also valid vice versa with respect to deflected partial flows 9b of the other wing 25b.
- the structure 25 arranged in the interior of the pipeline 1 is included two ring pieces 6 and 6 'connected between the ring 20 and the Flange 11 - see Fig. 1 - be inserted.
- the structure 25 is on the Axis of symmetry 53 folded so that the right dash in Fig. 4 drawn angle arises.
- Also between the ring pieces 6, 6 'and both wings 25a, 25b is folded in such a way that the ring pieces 6, 6 'come to lie in the same plane. After folding, they form Ring pieces 6 and 6 'at their ends 61 and 62 or 61' and 62 'joints.
- FIGS. 5 to 8 Two further exemplary embodiments of the invention are shown in FIGS. 5 to 8 shown. While in one example the number of open patches on one wing 25a is one and on the other wing 25b is two in the other example, this number two or three. In these examples the surface pattern 5 differ relatively strongly from the pattern of Frame of reference 4.
- the surface pattern 5 according to FIG. 5 (with corresponding surfaces 51, 52, 521, 522 and 51 'as in the first example, Fig. 4) can do the same Reference system as in the first example Fig. 3 are assigned.
- Fig. 6 shows an overlay of the surface pattern 5 and the reference system 4. Common areas of this overlay that are up to 30% smaller than the covering surface pieces 51, 521, 522 or partial surfaces 51 ', 52 of the Are surface pattern 5, 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. 7 The other mix-effective structure 5 with the somewhat more complicated one Surface pattern 5 is shown in FIG. 7.
- a correspondingly more complex reference system 4 namely that of Fig. 8 be taken as a basis.
- the mixing element 2 according to the invention is intended to lead to a mixing result, which is associated with the smallest possible pressure loss. Therefore, the open areas of the wings 25a and 25b overall are not essential be smaller than the free cross section of the pipeline 1. This condition is fulfilled if the above-mentioned open areas are at least in total have the same area as the closed partial areas and if the inclination of levels 21 and 22 is relatively large, so that of angle included at the intersection axis 23 of 120 ° or less is.
- the flange mixer 2 can with a suitable training in the Pipe 1 can be installed and removed without disassembly part of the pipeline 1 is required. This requires that the Wings 25a and 25b largely in the area between the two End cross sections 13, 14 of the ring 20 (see Fig. 1) are arranged.
- the mixing element 2 is well suited for adding an additive to feed the flange point 10 into the pipeline 1.
- Fig. 9 are Feed points for an additive 95 are shown, which are integrated in the ring 20 are. They are uniform by a plurality or a plurality arranged and equally large outlet openings 31 are formed.
- the Additive 95 is conveyed via a feed pipe 30 into an annular groove 3 'from which it through the outlet openings 31 into the effective range dash-dotted lines 25 'indicated mixer structure 25 arrives.
- feed pipes 30 for several additives or other fluids to be mixed may be provided.
- the many 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 one inserted seal (not shown) are milled.
- Feed points 30 'for fluid to be mixed can also be upstream the mixing element can be arranged as illustrated in FIG. 10. about a nozzle 31 'feeds a fluid upstream of the mixing element 2.
- the aperture 8 can also be part of the mix-effective structure 25 his; the structure 25 may be formed on the periphery so that it is as Ring aperture works.
- FIG. 12 shows a further mix-effective structure 25.
- This consists of a closed ring 6, which between the pipe flanges 11, 12 (Fig. 1) can be inserted, a first wing 25a, which consists of a middle Web is formed, and a second wing 25b, which consists of two lateral Webs 25b 'and 25b "is composed.
- the wings 25a and 25b are like this formed parts of them over the crossing axis 23 to the side of the other wing 25b or 25a protrude.
- the middle bridge or the Both side webs can be missing, so that the mixed structure 25 has only one wing 25a.
- a mixing element 2, one such reduced structure 25, is also an inventive Mixing element.
- An example of such a structure 25, which has only one wing is shown in Fig. 13; it is missing compared to the embodiment of FIG Fig. 12 of the wing with the lateral webs 25b 'and 25b ".
- the mix-effective structure 25 can be made of flexible material, for example be made of thin spring sheet or plastic. At different throughput, the webs bend differently; the Flow resistance grows less with increasing throughput quickly, 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 mixing structure 25 plane 21, 22 associated with the wing are bent out. So can in the example of FIG. 12, the two lateral webs 25b 'and 25b "around different angles can be bent out of the plane 22.
