Definitions
- viscosity of a fluid is independent of shear, it is called a Newtonian fluid. If the viscosity of a fluid depends on a shear, it is called a non-Newtonian fluid. If the viscosity of a fluid decreases with increasing shear, it is called a shear thinning fluid. If the viscosity of a fluid increases with increasing viscosity, this is called shear-thickening fluid.
- the static mixers are constructed, for example, of several mixing elements. These mixing elements are usually formed in one piece and may have an outer sleeve, in which one or more cross struts are introduced. These cross struts have substantially the shape of an elongated body, such as an elongated cuboid, cylinder or an elongated body with triangular, elliptical or other like base, which is introduced with the long side, ie the cross strut length, perpendicular to the main flow direction in the outer sleeve and at one of the two shorter sides, ie the width of the width, is both perpendicular to the long side and perpendicular to the main flow direction.
- an elongated body such as an elongated cuboid, cylinder or an elongated body with triangular, elliptical or other like base, which is introduced with the long side, ie the cross strut length, perpendicular to the main flow direction in the outer s
- the cross strut thickness ie the thickness of the cross strut. If there is more than one transverse strut, they are arranged parallel to one another in two planes, as seen in the main flow direction. Of these one or more cross struts goes on each side of the respective cross strut to the inner surface of the outer sleeve and / or to the nearest
- Cross strut at least one bridge off, such that the width of the openings, through the webs in free cross-section of the static mixer is equal to the width of the webs.
- the webs which extend from the same transverse strut in different directions, close an angle which is smaller than 180 °, the opening angle O.
- the mixing elements are installed in a 4 + 4 arrangement, ie, two mixing elements arranged immediately after each other twice are arranged as described above, wherein the second four mixing elements are immediately adjacent to the first four mixing elements, but the second four mixing elements are rotated 90 ° relative to the first four mixing elements in the plane normal to the main flow direction.
- 2 + 2, 2 + 3, 3 + 2, 3 + 3, 3 + 4, 4 + 3 or any other arrangements are possible.
- Arrangements of at least two immediately after the other arranged mixing elements are also called static mixer.
- the number of mixing elements is preferably a multiple of 3.
- the number of mixing elements is preferably a multiple of 4.
- a static mixer which consists of a tubular housing and contains at least one mixing element arranged therein.
- the mixing element consists of intersecting webs, which have an angle with respect to the tube axis.
- the webs of the mixing elements are arranged in at least two groups. The lands within each group are substantially parallel. The webs of one group intersect with the webs of the other group.
- EP0856353A1 shows a module which is part of a static mixer intended for a residence-time-critical, plastically flowable mix.
- the device comprises a tubular housing in which webs are arranged. The webs are inclined against the longitudinal axis of the housing; they essentially intersect on a straight line perpendicular to the longitudinal axis.
- the module comprises a sleeve which can be inserted into the housing.
- the mixing material conducting inner wall of the static mixer is formed by inner sides of the sleeve.
- the webs are formed like a spike, each with a pointing against the direction of movement of the mixed material vertex and attached to the sleeve inside base. Each vertex forms a gap with the interior wall of the device.
- WO2009000642A1 discloses mixing elements in which intermediate spaces are at least partially located between adjacent webs. In this way, an improvement of the
- the reduction of the pressure loss can be advantageously achieved by reducing the specific effect of the mixing element or static mixer.
- the specific effect is a dimensionless characteristic number for the description of mixing elements and static mixers into which the pressure loss in the mixing element or static mixer and the residence time of the fluid in the mixing element or static mixer are received in the numerator and the viscosity of the fluid enters the denominator.
- Detailed explanations of the specific effect can be found in Dolling, E.: "For the representation of mixing processes in highly viscous liquids", Dissertation RWTH Aachen, 1971.
- a further technical task may be to accomplish a given mixing task with equipment size and dwell time specified for reasons of quality and installation, with as little pressure loss as possible in order to save energy. Furthermore, it may be a technical task to reduce the temperature at required throughput, mixing quality and allowable pressure loss to increase the quality. As one skilled in the art knows, lowering the temperature of polymer melts typically slows down harmful side reactions and thus increases product quality, but at the same time the viscosity of polymer melts increases as the temperature is lowered, so that a limitation in pressure loss can occur.
- the object of the present invention is therefore to provide a mixing element which has a lower pressure loss with the same or better mixing result.
- This lower one Pressure loss is to be achieved without increasing the residence time or increasing the diameter or free volume of the mixing element or static mixer.
- the mixing result can be evaluated, for example, by measuring a concentration distribution at the outlet from the static mixers. Frequently, the concentration distribution is combined into an integral mixing quality.
- concentration distribution is combined into an integral mixing quality.
- transverse strut side which faces away from the webs, preferably has the shape of a rectangle, this rectangle being at right angles to the main flow direction of the fluids.
- the thickness of the webs (dS) is 0.01 to 0.07, preferably 0.015 to 0.06 and most preferably 0.02 to 0.05 times the diameter of the mixing element perpendicular to the main flow direction.
- the mixing element according to the invention may comprise a sleeve. If the mixing element according to the invention has a sleeve, the outer surfaces of the transverse struts and the end faces of the sleeve lie in one plane.
- the pressure loss can be further reduced by the mixing element according to the invention with the same or better mixing result, if in the main flow direction, the width of the opening between two adjacent webs, which lie on the same side of the cross member from which they depart larger is as the width of a bridge. In this case, this web width of these two webs is substantially equal.
- the mixing element according to the invention is additionally advantageous in that it has a smaller overall depth than a comparable mixing element from the prior art.
- a mixing element according to the invention has a construction depth reduced by twice the thickness of the transverse strut. This can certainly lead to an opening angle O of 90 ° and a conventional ratio of diameter of the static mixer to the thickness of the web of 20: 1, an approximately 20% smaller depth.
- the resulting space savings is technically desirable, especially because usually in a pipe that is traversed by the fluids to be mixed, not only a mixing element according to the invention, but many mixing elements according to the invention are incorporated.
- These then form - analogously to the static mixers of the prior art already described above - a static mixer according to the invention. This solves the additional task of providing a mixing element which, with the same or better mixing result and at the same time reducing the pressure loss, has a smaller overall depth than comparable mixing elements from the prior art.
- the smaller overall depth of the mixing element according to the invention causes a shorter residence time of the fluid to be mixed or of the fluids to be mixed with one another in the mixing element. This in turn reduces the thermal loads and thus in turn temperature-induced damage to the fluid to be mixed or the fluids to be mixed together.
- this arrangement according to the invention causes uniform flow of force.
- the force flows are transmitted through the webs without deflection directly from a mixing element according to the invention to the subsequent mixing element according to the invention, whereby moments at the transition between web and cross member and the associated additional shear stresses are avoided.
- the strength is increased.
- Further advantages of the mixing element according to the invention and the static mixer according to the invention are the material savings in the production of the mixer and that increased throughput is tolerable.
- the mixing element according to the invention it is not to be feared that a mixing element according to the invention or a static mixer built up from at least two mixing elements according to the invention will be compressed under the load of the flowing fluid.
- the mixing element according to the invention is suitable for higher load than a corresponding mixing element of the prior art and a static mixer constructed of at least two mixing elements according to the invention is suitable for higher load than a corresponding static mixer of the prior art.
- the advantages of the mixing element according to the invention emerge when at least two of the mixing elements according to the invention form a static mixer, that is, when the static mixer is composed exclusively of the mixing elements according to the invention.
- the subject matter of the present invention is therefore also a static mixer comprising at least two mixing elements according to the invention.
- subject of the present invention is also a static mixer, which is constructed exclusively of the mixing elements according to the invention.
- one or more or all of the mixing elements according to the invention may or may not have a sleeve.
- the static mixer according to the invention may or may not have a sleeve.
- Such a sleeve may have marker grooves or marker pins on the outside, which make it difficult or prevent incorrect installation or assembly of the mixing element or of the static mixer into a tube through which the fluids to be mixed flow.
- Another object of the present invention is also a method for mixing fluids using a mixing element according to the invention.
- another subject of the present invention is also a method for mixing using a static mixer according to the invention.
