  • the selectively at one point of the The additive is fed into the periphery of the lumen Rule after interference still as an uneven Concentration distribution in the fluid flow can be determined. Aperture-like internals also cause flow separation, which leads to large pressure drops to lead.
  • the object of the invention is to provide an intermediate flange ring in which admixture of an additive leads to a distribution which is compared to the distribution is more uniform with known intermediate flange rings, and / or with the smaller flow separations and thus less Pressure drops occur. This object is achieved by the in claim 1 defined intermediate flange ring released.

  • He comprises an outer ring 3 with at least one point 30 for Feeding the additive 10 and an inner, concentrically arranged Ring 4.
  • the inner ring 4 is largely the same width as the outer ring 3 and consists of a one-piece ring segment or a plurality of one-piece and axially arranged ring segments (see. Fig. 4).
  • the exterior Ring 3 and the inner ring 4 together close at least one Annulus 5 in which all or some of the feed points 30 open.
  • the inner ring 4 forms the outer surface 64 of a lumen 6, which is from Fluid flow 20 is flowed through.
  • the feed point can be designed as a connector 30, the elements for Connecting a pipeline, for example an internal thread (Fig. 2), a flange or a welding end.
  • the neck can formed together with the outer ring as a monolithic component his.
  • the intermediate flange 1 of FIG. 1 is a component of a single ring device arranged between the flanges 21 a, 21 b, the width b of the outer ring 3 except for the thicknesses d of two sealing rings 8a, 8b is equal to the distance a between the pipe sections 20a, 20b.
  • the Intermediate flange ring 1 can also be a component of a multi-ring device be made up of two or more axially arranged Intermediate flange rings 1 exists.
  • the additive 10 is a variety of Through openings 7 entered in the lumen 6.
  • the Passage openings 7 arranged on the input side and through a separate Sheet metal ring 70 is formed. They are evenly about axis 22 - over the Distributed circumference of the lumen 6 and lying on a circle - arranged.
  • the Sheet metal ring 70 is between the inner ring 4 and the flange 21 a Pipe piece 2a inserted; the passage openings 7 are through Recesses 71 of the sheet metal ring 70 are formed.
  • the passage openings 7 can also be in the form of bores and / or Slots are formed. It is in the embodiment of FIG. 4 Holes.
  • the inner ring 4 consists of two segments 4a and 4b, which each form an annular channel 5a and 5b. In each ring channel 5a, 5b opens at least one additive feed point 30, not shown.
  • the inner ring 4 consists of only one segment. Because of this Segment 4 can also be formed from a plurality of ring channels 5.
  • the diameter of the lumen 6 is usually the same size as that Inner diameter of the pipe sections 2a, 2b. It can also be smaller. In in this case, the intermediate flange 1 exerts the effect of an aperture, what is advantageous for mixing in the additive.
  • the intermediate flange ring 1 according to the invention can be used with a Mixing structure 9 - see Fig. 6 - to a flange mixer combine with the compared to the device that from US-A 5 839 828 is known, with a smaller pressure loss a better one Mixing effect can be achieved.
  • This flange mixer contains, for example Structure 9 having webs, which consists of a stamped piece 9a - see FIG. 5 - is made.

  • the two Planes intersect on an intersection axis that is transverse to the longitudinal axis of the cylindrical space. Closed patches as well as open ones Partial surfaces of the wings form a surface pattern that with respect to the Crossing axis is asymmetrical in a special way. (On Example is given by the structure shown in Fig. 6.
  • Asymmetric form becomes a fluid that enters the cylindrical space flows through forming tube, influenced in such a way that partial flows from each a pipe half through the closed surface pieces (webs 91 a, 91 b; 92) are diverted to the other half of the pipe, largely not there deflected partial flows encounter and be mixed with them. It this results in mixing over the entire pipe cross-section.
