Definitions

  • the invention relates to a nozzle separator according to the preamble of claim 1 and a method according to the preamble of claim 6.
  • the US 4 286 748 A called, which discloses a centrifuge-type washing device.
  • the technological background of spraying devices is also the US 1 714 232 A cited.
  • replacement wash in which a washing liquid is conducted into the interior of the drum with recirculation lines extending radially outward in the interior of the drum, so that these enter into the interior of the drum radially and radially having an axial velocity component.
  • the separated from the mother liquor solid phase is taken up by the washing solution and ejected as a washed washing suspension from the drum via nozzles as a nozzle phase from the drum ( Fig. 2 ).
  • the invention aims to reduce this problem.
  • the g-field is amplified by the additional peripheral speed.
  • the outlet openings of the supply pipes are located in the circumferential direction between the Feststoffaustragsö réelleen to achieve a particularly good effect of the type described above.
  • they can also lie radially in the extension of the outlet openings.
  • Fig. 2 shows a section through a lower part 1 designed as a nozzle drum for continuous operation Separatortrommel 2 with a vertical axis of rotation.
  • the separator drum 2 has solids discharge nozzles 3 in the region of its largest diameter.
  • the nozzle drum is rotatable by means of a drive, not shown here and has next to the in Fig. 2 components shown an inlet for a suspension to be processed, preferably a plate package of separating plates and one or more devices for the derivation of at least one liquid phase. Such devices are familiar to the skilled worker and require no further explanation here.
  • the separator drum has an arrangement 4 for adding washing liquid into the interior of the drum (see also for a better understanding Fig. 3 ).
  • This arrangement has an inlet for washing liquid (not visible here), which may be formed, for example, concentrically to the inlet (pipe) for the suspension to be processed.
  • the inlet for washing liquid opens into a distributor 5 (see also Fig. 3 ), which has a plurality of circumferentially distributed outlet openings which open into radially in the drum outwardly extending supply pipes 6 for distribution and supply of the washing liquid into the drum interior.
  • the distribution pipes 6 extend in the prior art in the drum radially outward until just before the Feststoffaustragsdüsen 3 in the drum wall 8. Between adjacent Feststoffaustragsdüsen 4 wall reinforcements in the form of packing 9 are arranged circumferentially distributed here, in the interior of the separator drum. 2 protrude and which direct out of the inlet pipes 1 washing liquid in the direction of the solids discharge nozzles 3.
  • the supply pipes 6 for the washing liquid serve to guide the washing liquid, usually a specifically lighter washing acid, into the interior of the drum in the region shortly before the solids discharge nozzles 3.
  • inlet pipes 6, which extend radially outward in the interior of the drum, in their radially outer region with an arcuate deflection section 7 which serves to redirect the washing liquid from the radial direction in the circumferential direction U (in the direction of rotation).
  • This deflection section 7 is after Fig.1 formed as a 90 ° -Rohrbogen, wherein the outlet opening of the pipe bend is directed in the circumferential direction of rotation U, so that the washing liquid leaves the deflection device in the direction of rotation U.
  • an outlet nozzle 10 may be arranged at the end of each supply pipe 6.
  • the deflection angle ⁇ in the circumferential direction U from the radial direction R is preferably between 45 ° and 120 ° (see also Fig. 4 ).
  • the Separatortrommel 2 on its inner wall preferably no more filling, so that the inner circumference is circular or cylindrical.
  • first washing liquid preferably a specific lighter scrubbing acid
  • first washing liquid is passed through the inlet pipes 6 in the edge region of the interior of the separator drum 2, where it exits in the circumferential direction U from the feed pipes 6 into the drum interior.
  • Fig. 5 shows a graph of product loss in the nozzle phase in% over the wash in m 3 / h.
