DETAILED DESCRIPTION OF THE INVENTION

[0026] FIG. 1 shows two vane profiles 1 arranged in parallel with one another for a mist eliminator unit of the prior art in vertical cross-section. The vane profiles form flow paths between them, through which a gas flows in order to remove liquid droplets carried in the gas. The removal process in this case takes place at deflection points that form corresponding separation zones and that are formed by edges 2 that are produced by bending planar sheet metal profiles.

[0027] FIG. 2 shows two vane profiles 10 configured according to the invention in vertical cross-section. In this case, the corresponding deflection points are not formed of sharp edges, but rather of round embossed portions 11, 12, 13, 14 that are produced by means of roll forming. Said round embossed portions extend in different directions, wherein the two round embossed portions 12, 13 are arranged next to one another and cause the profile to change direction. This is also the case for the round embossed portions 11, 14. In this case, too, the corresponding legs form an angle other than 180° with one another.

[0028] In this embodiment, it is clear to see that all direction changes of the profile are caused by round embossed portions, wherein said round embossed portions are effective with regard to the desired phase separation and can be produced in a particularly simple and quick manner by means of a corresponding roll forming machine, for example.

[0029] FIG. 3 schematically shows the production of a vane profile 10 provided with round embossed portions 11. The round embossed portion 11 shown in the center is produced by means of a roller 16 that is provided with a corresponding profile and that, for example, forms an angle of 90° with the metal strip. The two lateral rollers 15, 17 are arranged obliquely with respect to the plane of the metal strip and produce corresponding round embossed portions while also angling the strip.

[0030] FIG. 4 shows another embodiment of vane profiles 20 in cross-section. The respective profiles have two round embossed portions 21, 22, wherein the round embossed portion 22 is arranged in the shape of a pocket, whereas the round embossed portion 21 is approximately semi-circular in cross-section and causes the profile to change direction.

[0031] FIGS. 5a-c schematically shows three stages for producing a vane profile. FIG. 5a shows a planar metal strip 30 in cross-section. FIG. 5b shows how a round embossed portion 31 is created in the planar metal strip by means of a roller 33 of a corresponding roll forming machine. In another step, shown in FIG. 5c, two other round embossed portions 32 with angled metal strip regions are created by means of two inclined rollers 34.

[0032] It should be understood that the procedure represented schematically in FIGS. 5a-c is merely an exemplary embodiment for the production of a vane profile. What is essential is that a vane profile is produced which has at least one separation zone comprising at least one embossed portion produced by means of roll forming for removing liquid droplets from a gas flow.
