Definitions

  • the invention relates to a static micromixer with a mixing chamber, feeds for at least two fluid fractions to be mixed or dispersed, each having at least one confluence with the mixing chamber and at least one orifice out of the mixing chamber according to claim 1.
  • a micromixer In a micromixer, the fluids to be mixed, each separately separated, are divided into a large number (often several thousand) of fluid flow filaments, all of which open into a mixing chamber via the inlets via the junctions.
  • a static micromixer is characterized by the fact that there are no moving parts in it except for the fluid fractions to be mixed.
  • Such a micromixer with at least one mixing chamber and an upstream guide component for the separate supply of fluids to be mixed to a mixing chamber is known, wherein the guide member with dimensions in the millimeter range of several superimposed films is composed with a respective thickness of about 100 microns thick , in which the channels are incorporated as microstructures.
  • the channels of a film comprise feeds for only one of the two fluid fractions.
  • a similar micromixer in which the supply channels of two fluids to be mixed or mixed open out in an arcuate manner parallel to one another into the mixing chamber, with otherwise the same design and functional principle DE 195 40 292 C1 described.
  • the guide channels have a constant cross-section with widths less than 250 microns, the films in which the channel structures are incorporated, a thickness of about 100 microns.
  • a static micromixer for mixing at least two fluids comprising a plurality of stacked structured films.
  • the mixing chamber is formed by a circular breakthrough in a film, wherein the junctions of the two fluids on the same film incorporated in an alternating order in a plane over the entire mixing chamber height over the cylindrical wall of the mixing chamber are arranged.
  • a two-dimensional spiral flow arises in the mixing chamber, which opens into a bore arranged centrally around the axis of symmetry of the mixing chamber on an end face of the mixing chamber (formed by a foil surface delimiting the mixing chamber).
  • a similar mixing apparatus for mixing at least two fluids with spiral flow guidance is also in the WO 02/089966 A2 described.
  • the fluids are additionally mixed in separate mixers in the supply lines before entering the mixing chamber.
  • a spiral flow guide of the aforementioned type is naturally associated with a flow constriction, which significantly limits the possible throughput or causes an increasing flow velocity.
  • centrifugal forces of the basic flow direction towards the center of the mixing chamber counteract the fluid in the flow spiral. Both influences increase a certain back pressure in the mixing chamber and thus also the probability of turbulent flow components.
  • US 5,573,334 discloses a static mixer for two fluid fractions, comprising a cylindrical mixing chamber with two end portions, one each per fluid fraction and a common orifice are positioned in each one of the end regions. Also realized here in the orifice by a concentric bore in the bottom of the cylindrical mixing chamber - in principle associated with the aforementioned effects.
  • the object of the invention is to propose a static micromixer of the generic type with an improved mixing efficiency already in the laminar fluid flow, said said obstructing the flow obstructing and limiting disadvantages should be reduced.
  • the invention comprises a rotationally symmetrical mixing chamber having an axis of symmetry and two end regions, a number of feeds for at least two fluid fractions to be mixed or dispersed, each having at least one confluence with the mixing chamber and at least one orifice from the mixing chamber. All junctions are located exclusively in one of the two end regions, while the orifices are positioned in the other end region. Preferably, the junctions of the fluid fractions are over the circumference of the shell surface of the mixing chamber, i. not arranged on the end face in alternating order in one or more planes.
  • An essential feature of the invention relates to the arrangement of the junctions of the fluid fractions in the mixing chamber, in alternating order.
  • the alternating sequence of the junctions and thus of the fluid flow filaments flowing into the mixing chamber thus ensures a high specific mixing surface between the fluid fractions to be mixed or dispersed in the mixing chamber.
  • An essential feature of the invention comprises a non-concentric arrangement of the orifice in the mixing chamber.
  • the orifices are arranged in the outer region of the mixing chamber, preferably the lateral surface.
  • turbulent flow components fundamentally improve the efficiency of a mixing or dispersion of the fluid flow filaments in the mixing chamber, however, they also cause larger residence time differences of the fluid mixtures in the mixing chamber to be avoided in certain, in particular reactive mixing processes. By avoiding or reducing turbulent flow, the abovementioned residence time differences also advantageously decrease, in particular in comparison with the devices according to the prior art.
  • each of the fluid flow filaments is completely adjacent, ie on all sides, to fluid flow filaments of another fluid fraction, thus providing the greatest possible mixing surface area between the fluid fractions and as a result a further improvement of the mixing efficiency can be achieved.
  • mixing or dispersing two fluid fractions is ideally created an arrangement of the individual junction cross-sections similar to a checkerboard arrangement.
  • junctions for generating a preferred helical fluid guide in the mixing chamber are arranged tangentially, preferably with a small pitch angle to the lateral surface of the mixing chamber serving as a wall.
  • the object is achieved in that the layers are formed by stacked films with grooves as fluid guides, wherein the feeds per fluid fraction via fluid channels, comprising superimposed openings in the films, are fluidly interconnected.
  • the superimposed openings form in the film stack, the fluid channels from which branch off the fluid guides to the mixing chamber.
  • the fluid connections to the fluid channels are preferably placed on the respective limiting outer cover film.
  • a feed can also be realized via channels on one or more foils, the preferably limiting outer cover foils sealingly covering the fluid channels.
  • the aforementioned low pitch angle of the junctions can be achieved, for example, by designing the foils completely or only in the area of the junctions, ie directly in the wall of the mixing chamber as a truncated cone lateral surfaces. This can be achieved, for example, via cold forming of the individual films or of the film stack prior to the connection of the films to one another with respect to the guide component, for example via diffusion bonding.
  • the fluid channels with appropriate means for measurements such as e.g. a thermocouple or for a temperature control or a pressure measurement such. equipped with a heating element or a fluidic heat exchanger and dimensioned accordingly, which can be tailored to the fluid fractions in an advantageous manner immediately before entering the fluid guides individually.
