Definitions

  • the invention relates to a static mixing device for fluids containing or consisting of solid particles according to the preamble of claim 1.
  • the known static mixing devices such as are described, for example, in Swiss Patents 642 564, 547 120 or 578 370, all have the disadvantage that they tend to become blocked when fluids containing or consisting of solid particles are used.
  • Such fluids can e.g. consist of different granules which are to be mixed homogeneously with one another or be liquids which contain fibers or other solid particles, for example.
  • Such cases occur, for example, in municipal wastewater treatment, e.g. when mixing chemicals in sludge, in the paper industry or also in the food industry, e.g. when mixing fruit pieces in yogurt.
  • the invention is based, for media of the type mentioned above, i. even fluids consisting of piece goods or containing piece goods to create a blockage-free, static mixing device, which also ensures homogeneous mixing with an acceptable pressure loss.
  • the design according to the invention of a static mixing device prevents the settling or catching of solid particles between the webs and the casing tube wall or between crossing webs with simple means, so that a perfect mixing can be carried out in the device.
  • the outer webs or the one ends of the inner webs can be welded or soldered to the tube wall, for example.
  • the device cross section can be both circular and have a different contour, e.g. be a rectangle.
  • the web cross sections can taper towards the free ends.
  • the cross sections and the longitudinal section shapes advantageously have aerodynamic contours, e.g. rectangular, elliptical or semicircular.
  • the angle between the webs and the tube axis is advantageously in the range from 3u to 60 °, in particular 45 and 30 °.
  • an advantageous development of the invention can consist in that the successive ones Mixing elements are each arranged at an angle, in particular offset by 90 °, in the housing. This ensures spatial homogeneity.
  • Another application may, for example in the mixing flocculant chemicals in secondary sewage sludge exist for sludge dewatering in front of a Z entrifugaldekanter of a municipal sewage treatment plant.
  • the installation of a mixer according to the invention takes into account the requirement for an efficient use of the quantity of chemicals for rapid and uniform mixing.
  • each mixing element consists of three webs 2a to 2c, with a space remaining between the crossing webs, as can be clearly seen from FIGS. 2a to 2d. It may be expedient to provide groove-like constrictions at the crossing points in order to enlarge the free space.
  • FIGS. 1 to 2d is a particularly advantageous embodiment, it is in principle also possible, depending on the process in which the mixing device is to be used, to design the mixing device with a plurality of webs. 3 and 4, a mixing element is shown, which is arranged in a tube 3 and which consists of two outer webs 4a and 4e and inner webs 4b to 4d.
