Definitions
- the invention relates to a mixing tube for low viscosity Fluids, in particular for fluids with suspended contained solids, according to the preamble of claim 1.
- This device includes Mixing elements in a tube, each consisting of two outer segments and at least one inner segment consist. The segments are at one end or sides with the housing gap-free connected while their other ends are at a distance end in front of the pipe wall. Adjacent segments intersect with a gap at each intersection remains. The mixing takes place essentially within the mixing elements by a crosswise deflection individual partial flows.
- the object of the invention is to provide a mixing tube to create static internals in terms of known static mixing device cheaper can be produced.
- This task is claimed by the 1 defined mixing tube solved, in which the mixture due to the bottlenecks mentioned in the claim and the subsequent bottlenecks of mixed routes.
- a Such a mixing device is also for low-viscosity Liquids that do not contain solids can be used.
- the mixing tube according to the invention for low-viscosity fluids contains plate-shaped elements attached to or on individual parts of the tube, its cross section partially cover.
- the bottlenecks left open by the elements each comprise at least one gap-shaped area, with a longitudinal extension of this gap, that of Pipe wall to pipe wall through the pipe axis or from the Pipe wall through the pipe axis to a second section runs.
- the gap closes with the pipe axis Angles in the range between around 20 and 60 °, preferably between 35 and 45 °, a.
- the one Length in the range of 1 to 10 pipe diameters.
- the bottleneck or bottlenecks of the invention Mixing devices are shaped and arranged such that in the flowing fluid as it passes through a Bottleneck two opposite vortices form. While of the flow through the mixing section results in Whirl a partial mixing. Compared to the known mixing device are fewer mixing elements and for each mixing element only two segments are required to create one to achieve largely the same good mixing effect. However, a longer pipe is required. Further causes the mixing device according to the invention lower pressure drop.
- the dependent claims 2 to 11 relate to advantageous Embodiments of the mixing tube according to the invention.
- the Claim 12 relates to the use of Mixing tube.
- Figures 1 and 2 represent an inventive Mixing tube 1 for low-viscosity fluids.
- the tube wall 10 is only indicated by dash-dotted lines.
- the circular Pipe has a diameter D.
- the mixing pipe 1 contains plate-shaped elements 2 as internals, the individual Place the tube 1 partially cover its cross section and create bottlenecks 3.
- the elements 2 are in elliptical surfaces with the main axes d and e arranged.
- the bottleneck 3 released in the elements 2 includes two sections 31 and 32: a wide gap 31, the from the pipe wall 10 through the pipe axis c to the second portion 32 extends along the axis e, and a flow opening 32 adjoining the tube wall 10 of an elongated, here crescent-like shape, the is arranged transversely to the first partial region 31.
- the shape of the second partial area 32 can also be, for example be lenticular.
- the axis e (or the gap 31) closes with the Pipe axis c an angle ⁇ in the range between around 20 and 60 °, preferably between 35 and 45 °.
- the second section 32 is downstream after the gap 31 arranged. After the bottleneck 3 there is a mixed section 4th
- edges these segments essentially include the following Sections: an edge piece a with the shape of a elliptical arc adjacent to tube wall 10; on straight edge piece s, which forms a boundary with the gap 31; and an edge piece b that connects to the second partial area 32 of the bottleneck 3.
- Between the tube wall 10 and the arcuate edge a can be a small gap located at individual points Connecting means, for example welding material, are bridged.
- the elliptical border can, for example be approximated by straight pieces.
- Edge piece s can also be a curved one.
- the flowing fluid is in Fig.1 by arrows 5, 5 ' indicated.
- the bottleneck 3 induces two in the flow opposite vortices that are projected onto a Cross-sectional area are indicated with arrows 6, 6 '.
- the gap 31 is essentially trapezoidal (corner points A, B, B 'and A'); it widens towards the second Subarea 32 of the bottleneck 3. With this slit shape creates an optimal pair of vertebrae 6, 6 '. So that two Bottleneck is 3 mirror-symmetrical; the plane of symmetry lies on the pipe axis c.
- the plate-shaped elements associated with a bottleneck 3 2 are in the embodiment of Figures 1 and 2 in arranged on one level. You can be together with the Manufacture connecting web 23 from a piece of sheet metal. Figure 3 shows how these elements 2 material-saving from one Strips of sheet metal can be cut out.
- the plate-shaped elements 2 can instead of just be curved or kinked.
- bottlenecks 3 in the mixing tube 1 there are at least two bottlenecks 3 in the mixing tube 1 provided, one each to a first bottleneck 3 adjacent, downstream bottleneck 3 ' outside the mixing section 4 at a distance m of around 3 to 5 pipe diameters D is arranged.
- the free space between adjacent bottlenecks 3, 3 ' thus has a length of around 2 to 4 pipe diameters D. on.
- the gaps 31 of adjacent bottlenecks 3, 3 ' are transverse arranged to each other.
- Figures 4 to 8 represent further embodiments possible bottlenecks 3.
- the two are in Fig.4 Segments 21 and 22, which have the same shape, are angular arranged to each other.
- the shape of the segment 21 or 22 can be seen in Fig. 5.
- the segments 21 and 22 can of course also by a web 23 - for example, as shown in dashed lines - connected his.
- Figures 6 and 7 show bottlenecks 3 for Mixing tubes 1 according to the invention, their cross sections are square or rectangular.
- Fig. 6 also shows that a web 23 at a different location than at the Border between the two sections of the bottleneck 3 can be arranged.
- the web 23 can be, for example Be a rod with a circular cross-section.
- the fifth exemplary embodiment according to FIG. 8 shows one Bottleneck 3, which only consists of a gap-shaped area 31 consists.
- the area 31 can be trapezoidal (with two curved sides AA ', BB') and thereby in or against expand the direction of flow.
- the mixing tube 1 according to the invention can mix a Fluids with suspended solids are used become. Especially if the solids are fibrous, this use is advantageous.
