Abstract
The invention relates to mixing elements with a reduced structural depth for static mixers, to static mixers comprising at least two mixing elements with a reduced structural depth, and to a method for mixing fluids using a mixing element with a reduced structural depth or a static mixer comprising at least two mixing elements with a reduced structural depth. In the mixing elements, the thickness of the transverse strut at its thickest point is maximally 0.9 to 1.1 times the thickness of the webs multiplied by the cosine of half the opening angle O divided by the sine of the whole opening angle O.
Claims9
A mixing element which has at least one transverse strut from which there originate, at right angles to the longest extent of the transverse strut, at least three webs, at least one web of these at least three webs lying in alternation with at least two webs of the at least three webs with respect to the longest extent of the transverse strut, and the webs lying on opposite sides of the transverse strut enclosing an opening angle O of 60° to 120°, wherein the thickness of the transverse strut (dQ) at its thickest point is not more than 0.9 to 1.1 times the thickness of the webs (dS) multiplied by the cosine of half the opening angle O divided by the sine of the full opening angle O.
