Definitions
- Static mixers are often used to mix liquids: One The pump presses the liquid through a static mixer built-in Pipe, the liquid being sheared at the mixer and divided into partial flows that are to be mixed together.
- Kenics mixers With the so-called Kenics mixers (see “Mixing during manufacture and processing von Kunststoffe ", publisher VDI Ges. Kunststofftechnik, VDI publishing house 1986, pp. 238-241) the liquid flow of the mixed material through a in the tube built-in divider divided into partial flows. This divider is around that Tube axis twisted. A vortex-shaped is created in each of the partial flows of the liquid Flow leading to redistribution of the liquid in the cross section of the pipe leads.
- several such mixing elements are arranged one behind the other, to divide the liquid again and again and a sufficient mixing result to achieve.
- the pressure stability of these mixers against highly viscous fluids is however comparatively small.
- SMX mixers consist of two or more mutually perpendicular grids of parallel sheet metal strips, the are welded together at their crossing points and at an angle are set against the main flow direction of the mixture to the liquid to be able to divide and mix.
- the manufacturing effort for these mixers is because of the many welded joints to be made relatively high.
- Heat exchangers typically take place at a very low Reynolds number. If, for example, smooth pipes are used for heat exchange, one is against Zero Reynolds number the heat exchange rate extremely low and on the part of the For a given throughput, the heat exchanger essentially only depends on the pipe length used. A significant improvement in heat exchange is then possible by combining the tubular heat exchanger with a static one Mixing device.
- the object of the invention is to provide a static mixer that can be cooled or is heatable and can be produced in a comparatively simple manner.
- the invention relates to a static mixer insert, consisting at least from two or more layers arranged side by side, in particular to each other parallel webs, the webs being adjacent layers of webs cross and the webs are connected to each other at the crossing points characterized in that the web positions at their crossing points of heat transfer channels are crossed.
- the heat transfer channels preferably run at an angle alpha 60 60 ° to Level of the jetty.
- the heat transfer channels can be separated into individual supply lines and outlets Heat transfer medium open.
- a preferred variant of the static mixer insert is designed so that the Webs are at least partially designed as hollow webs, the additional channels for have a heat transfer medium.
- the webs are in a preferred embodiment of the mixer to the main flow direction of the mix at an angle, in particular from 30 to 50 ° or from -30 up to -50 °, which ensures a good division of the mix flow into partial flows is effected.
- the heat transfer channels are or the channels that run through the hollow webs meandering at their entrances and exits connected with each other. This creates a composite of heat transfer lines created that only a few supply and discharge lines for the heat transfer medium having.
- the invention also relates to a static mixer insert, consisting at least of two or more layers of juxtaposed, in particular webs parallel to one another, in particular with a rectangular cross section, with cross the webs of adjacent layers of webs and the webs on the Junction points are interconnected, characterized in that the Bridges are designed as hollow webs, which have channels for a heat transfer medium.
- the mixer insert is not on the Crossing points penetrated by additional heat transfer channels through the Jetty runs.
- the heat transfer channels can also be used with this form of static mixer use lead into individual supply lines and discharge lines for a heat transfer medium.
- the webs of this design which are only equipped with hollow webs as channels is to the main direction of flow of the mixture by an angle, in particular from 30 to 50 ° or from -30 to -50 °.
- the heat transfer channels of this static mixer insert can also be meandering be connected at their entrances and exits.
- Another object of the invention is a static mixer consisting of at least one of the mixer inserts according to the invention mentioned and an inner housing, that encloses the mixer insert and in the openings for the supply line and derivation of the heat transfer medium either to the crossing the web layers Heat transfer channels or to the channels running along the webs or to both are provided.
- the heat transfer channels or the channels of the hollow webs are preferably directly connected to the Openings in the inner housing are connected;
- a particularly preferred static mixer is constructed so that the inner housing is still enclosed by an additional outer housing, the at least one Has inlet connection and an outlet connection for the heat transfer medium and with the inner housing an inlet space and an outlet space for the heat transfer medium forms and has an inlet and an outlet for the mix.
- mixer inserts arranged one above the other in the inner housing and adjacent mixer inserts are each other about their central axis twisted arranged.
- the structure of the static mixer element according to the invention and of the invention static mixer allows this by injection molding one Manufacture workpiece, from the webs and from the heat transfer channels pierced inner case walls by adding sliders in the injection mold create the spaces between the webs and the heat transfer channels.
- This workpiece can either be itself in an outer housing, e.g. a pipeline, be installed or serve as a lost model for the investment casting.
- each web of a web position ends up to a maximum a web only at one end of the web on an inner housing wall, while the shows other end in the product stream.
- This design enables injection molding to spray all inner housing walls together with the webs, as all Spaces between the webs are accessible to sliders. This will make the Joining effort to complete mixer reduced
- a manufacturing process is particularly preferred, in which a primary molding process, the part of the inner housing walls that the Is penetrated heat transfer channels, is produced with.
- the heat transfer from the heat transfer medium to the mix improves because the Heat conduction paths from the heat transfer medium to the product can be shortened.
- the described heatable or coolable static mixer not only applied there be where static mixing is required, but can be done from a cost perspective other heat exchangers, e.g. Shell and tube heat exchangers as Capacitors, replace.
- FIGS 1a to c show a view of the invention from different views Mixer.
- the outer housing is only shown schematically.
- the mixer consists of an outer housing 1 with product inlet 2, product outlet 3 and inlet nozzle 4, 6 and outlet nozzle 5, 7 for the heating / cooling medium and the mixer inserts 8, 10 with inner housing 11,
- the internals shown in FIG. 2 are located inside the mixer each made of 90 ° rotated against each other, stacked mixing elements 8, 10, which are separated from one another by separating plates 9 on the temperature medium side to control the flow direction of the temperature control medium. With others Arrangement of the dividers can reduce the number of heating / cooling medium nozzles are accepting a higher pressure drop.
- Figures 3a to c show a mixing element (8) from different views. It consists of the inner housing section 300 and alternating layers of parallel Ridges 301 to 306 or 311 to 317 (in part only recognizable in section in Figure 4). The Bars of two successive layers of bars intersect under one Angle of 90 ° and have an angle of 45 ° to the product flow direction.
- the webs are hollow and have heating / cooling channels 362 to 367 and 371 to 377 (Fig. 4). In order to achieve a flow through the channels, these are through the Layers crossing the webs connecting channels 380, 381, 390, 391, 392 with each other connected (see the section in Fig. 4). From each landing 301 to 306, 311 to 317 only one web 304 or 314 extends from one housing inner wall to the opposite Interior wall. All other webs have a free end.
- Figure 5 shows an alternative structure of a mixing element, as in an inventive Mixer can be used.
- On the heating / cooling channels along the Bridges have been dispensed with in favor of simple production, but that is enough Layers of the cross-over cooling channels 580 to 592 through the inner housing of the Mixing element.
- Such a mixing element is particularly suitable for highly viscous products which have the main thermal resistance on the product side and the additional one Thermal resistance due to heat conduction in the now solid webs does not ins Weight drops.
- Figure 6 shows a section through the mixing element of Fig. 5 analogous to the section A-A from Figure 3b.
