Definitions

  • the invention relates to a static mixer unit for mixing at least two fluids, in particular liquids, gases and/or pasty masses, which has a static mixer with several flow-influencing elements arranged in a hollow body.
  • the invention further relates to a set of parts comprising a static mixer unit, at least two, in particular exactly two, containers, each with an outlet on the containers, wherein the containers each contain one of at least two, in particular exactly two, different fluids.
  • the invention also relates to a method for mixing at least two fluids, in particular liquids, gases and/or pasty masses, with a static mixer unit and the use of a static mixer unit for mixing two fluids.
  • Static mixers are devices for mixing fluids in which the flow movement alone causes the mixing and which do not have moving elements. They consist of a series of specially shaped flow-influencing elements arranged in a pipe or housing. The fluids to be mixed are guided through these elements, whereby they are divided, diverted and recombined. This creates shear forces, turbulence or extensional flows that cause a homogeneous distribution of the fluids to be mixed.
  • Conventional static mixers work exclusively through the kinetic energy of the flowing media and do not require an external energy supply for the mixing process.
  • Static mixers are widely used in the construction sector, in industrial manufacturing or in industrial process engineering, among others, and have established themselves in numerous applications as a reliable and efficient solution for mixing liquids, gases and viscous media.
  • Such mixers are described, for example, in the patent documents US 4,062,524 (Bayer AG ), US 2012/0106290 A1 (Meijer et al. ), US 3,664,638 (Kenics Corp .), EP 0 815 929 B1 (Sulzer Chemtech AG ) and EP 2 181 827 B1 (Sulzer Mixpac AG ).
