Abstract
In a static micromixer which comprises at least one mixing chamber and one guide component disposed upstream of the mixing chamber and which includes channels extending therethrough at an angle to the longitudinal axis of the micromixer, so that the channels of alternate layers intersect without communicating with each other, the cross-section of the channels decreases steadily from the entrance end to the exit end of the guide component so as to reduce the pressure losses of the fluid flowing through the channels for mixing in the mixing chamber.
Claims8
A static micromixer with at least one mixing chamber (4) and an upstream guide component (1) for the separate admission of two different fluids (a, b) to be mixed or too be dispersed, said guide component (1) including for each of said fluid flows at least two slot-like flat channels (5a, 5b) extending at an angle with respect to, and from opposite sides of a plane extending along a longitudinal axis (16) of the micromixer such that said channels intersect each other in mutually spaced relationship and in an alternating fashion at an exit area to said mixing chamber (4), where they form a common exit cross-section of alternatingly arranged outlets of said slot-like channels for said different fluids (a, b), with webs disposed between adjacent outlets at the exit cross-section (3a, 3b) the height of the webs being less than 500 μm, said chactaeis in said guide component having, for at least a part of the fluid flows to be mixed, a cross-section which decreases from the channel inlet sides continuously toward and up to the channel exit area.
