Definitions

  • the invention relates to a cyclone, in particular for multi-stage heat exchangers, with an external inlet spiral and a gas line which is supplied from below and is deflected approximately at right angles directly in front of the inlet spiral.
  • Multi-stage cyclone heat exchangers are used, for example, as preheaters in cement kilns.
  • efforts are being made to further reduce the overall volume of the cyclones.
  • considerable separation problems arise.
  • the outer inlet spiral should extend over a circumferential angle of at least 180 °.
  • this requires a considerable volume and the weight of the cyclone.
  • the gas flow undergoes an approximately right-angled deflection before entering the cyclone, which leads to a separation of the dust in the gas and results in a particularly high dust accumulation in the uppermost part of the inlet spiral.
  • a known preheater (FR-A-1 454685) two cyclones are arranged directly one above the other, the funnel of the upper cyclone connecting to the gas outlet opening of the lower cyclone.
  • the gas supply line to this cyclone stage is split; one partial line opens into the lower cyclone and the other partial line opens into the upper cyclone.
  • the invention is based on the object of designing a cyclone of the type mentioned in such a way that the construction volume and the dead weight are substantially reduced with approximately the same pressure loss and degree of separation.
  • the invention thus makes use of the knowledge that, on the one hand, a longer separation path and a higher centrifugal force are required in the upper area of the entry spiral because of the higher dust load present there (due to the deflection of the gas flow in the gas supply line), and on the other hand a reduction in the length of the entry spiral in the lower area, a reduction in the diameter of the cyclone housing in this lower area, and thus a substantial reduction in the construction volume of the cyclone, is made possible.
  • the required height of the cyclone funnel depends on the diameter of the cyclone housing at the upper edge of the funnel; this housing diameter is significantly reduced by the subdivision of the entry spiral according to the invention and the lengthwise gradation of the partial spirals.
  • the entry spiral is expediently divided into at least three partial spirals, preferably of the same height.
  • the size of dust deposits on the crescent-shaped bottoms of the partial spirals depend on the size of the surface of these crescent-shaped bottoms. If the entry spiral is divided into several partial spirals, the bottom surface of the individual partial spirals is comparatively small, so that no disturbances due to dust deposits can occur.
  • the uppermost partial spiral expediently extends over a circumferential angle between 180 ° and 360 ° and the lowermost partial spiral over a circumferential angle between 90 and 180 °, preferably between 135 and 180 °.
  • the length of the partial spirals in between is graded accordingly.
  • the cyclone according to the invention is designed without an immersion tube (as is particularly expedient in the hottest stages of a multi-stage heat exchanger), all the partial spirals open into the diameter of the cyclone housing This corresponds to the diameter of the gas outlet opening of this cyclone.
  • all the partial spirals open out into the diameter of the cyclone housing, which corresponds to the diameter of the gas outlet opening of an equivalent cyclone designed without an dip tube.
  • the cyclone 1 shown in FIGS. 1 to 3 contains an inlet spiral 2, which is connected to a gas supply line, not shown, which is supplied from below and is deflected approximately at right angles, and which is divided into three partial spirals 3, 4 and 5 lying one above the other. These three partial spirals 3, 4 and 5 have a different length, decreasing from top to bottom.
  • the uppermost partial spiral 3 extends over a circumferential angle of approximately 270 °, the central partial spiral 4 over a circumferential angle of approximately 180 ° and the lowest partial spiral 5 over a circumferential angle of approximately 135 °.
  • All partial spirals 3, 4 and 5 open out in the diameter D of the cyclone housing, which corresponds to the diameter of the gas outlet opening 6 of this cyclone, which is designed without a dip tube.
  • a material discharge funnel 8 is connected to the lowest partial spiral 4 via a relatively short cylindrical connecting piece 7.
  • FIG. 4 differs from the cyclone shown in FIGS. 1 to 3 only in the presence of an immersion tube 9.
  • the diameter d of this immersion tube is somewhat smaller than the diameter D of the cyclone housing in which the partial spirals 3, 4 and 5 of the entry spiral 2 open out.
