Definitions

  • the invention relates to a cyclone separator according to the introductory part of patent claim 1.
  • Such a cyclone separator is known from DE-C-936488.
  • the hollow discharge lock in this case has a conical section tapering upwards in the solid collection container and a cylinder section protruding into the funnel section of the cyclone housing, as a result of which an annular gap is present between the lower edge of the funnel section opening into the solid collection container and the discharge lock.
  • the invention solves the problem of further increasing the degree of separation of a cyclone separator of the type mentioned at the outset and in particular to ensure that solid particles flowing downward into the solids collection container on the wall of the funnel section are not whirled up again as far as possible.
  • the solids discharge lock acts on the one hand in the funnel section as a vortex limiter and as a guiding device for deflecting the gas flow upwards, and on the other hand uses the negative pressure prevailing in the core of the vortex rotating in the cyclone container to suck gas back from the gas space of the solids collection container into the separation space of the cyclone separator. It arises in Annular gap between the discharge lock and the cyclone housing wall surrounding it, a mainly downward gas flow, from which the flowing away of the separated solid strands into the solid collection container is promoted and prevents an upward directed countercurrent view leading out of the solid collection container from forming in this annular gap.
  • the solids discharge lock is also designed as a cone within the solids collection container, which, however, tapers downwards.
  • the residual swirl of the gas flow entering the collecting container is further reduced, in particular if a solid discharge collar protrudes into the collecting container around the solids discharge lock and widens downward at least in its lower section.
  • the solids discharge lock can be supported on the wall of the cyclone housing or the solids collection container using support struts.
  • the solids discharge lock is carried over the solids collection container by a blade ring with inclined blades. This closes with its blades on the surrounding housing wall The blade ring contributes to the fact that a countercurrent sifting through gas flowing back from the solid collecting container through the annular gap formed between the discharge lock and the surrounding wall does not form.
  • the interior of the solids discharge sluice is connected to the cyclone inlet channel via a return line and a suction fan which promotes the inlet channel is switched into the return line.
  • a suction fan which promotes the inlet channel is switched into the return line.
  • the support elements supporting the discharge lock are preferably used.
  • the solids discharge lock in the solids collection container can be supported on hollow support struts which open into the discharge lock and to which the return line is connected.
  • the embodiments of the cyclone separator each have a cyclone housing with an upper cylindrical housing section 1 and a funnel section 4 which adjoins downwards and tapers downwards and opens into a solids collecting container 5 via a cylindrical solids discharge pipe 8.
  • the solids collection container 5 has an upper cylindrical section with a diameter which is substantially larger than that of the discharge tube 8 and a section which tapers conically downwards.
  • a spiral inlet channel 2 opens into the cylindrical housing section 1 of the cyclone separator and a dip tube 3 protrudes from above to discharge the clean gas flow.
  • a solids discharge lock 6 is installed concentrically, which projects upwards into the funnel section 4 and downwards into the solids collecting container 5.
  • the discharge lock is formed within the funnel section 4 as an upwardly tapering slim cone and, in the embodiments shown, extends within the funnel section 4 over approximately two thirds of the length of the funnel section.
  • the discharge lock 6 is cylindrical within the discharge tube 8 and, at its lower end projecting into the solids collecting container 5, is designed as a cone tapering downwards.
  • a discharge collar 7 projects downwards into the solids collecting container 5 around the discharge lock.
  • the solids discharge lock 6 is hollow and open upwards into the funnel section 4 and downwards into the solids collection container 5.
  • the solids discharge lock 6 is supported on oblique support struts 13 on the wall of the solids collecting container 5.
  • These support struts 13 are hollow, open into the discharge lock 6 and are connected externally to a return line 11 which is returned to the inlet channel 2 of the cyclone separator with the interposition of a suction blower 12.
  • gas and fine solid particles carried by it are discharged in the lower part of the interior of the solids discharge lock 6 and returned to the zykon inlet channel 2.
  • the solids discharge lock is fastened in the discharge pipe 8 with the aid of a blade ring 9 with inclined blades. This additionally prevents constructively that between the discharge lock 6 and the discharge tube 8 an upward directed flow out of the solids collection container is formed, which would lead to a countercurrent sifting.
