Definitions

  • the invention relates to a cyclone separator, in particular for direct heat transfer from the hot exhaust gases of a rotary kiln cyclone suspended gas heat exchanger system for the production of cement clinker on the cement raw meal, with tangential feed of Gas and raw meal, good discharge in the lower cyclone area and with a centrally protruding into the cyclone separator from above and suspended from the cyclone ceiling, composed of several segments Dip tube for gas discharge, the dip tube segments at its upper end by bolts with the gas exhaust line insulated by refractory lining detachably connected are.
  • the raw meal is preheated, calcined, sintered and cooled thermally treated, the exhaust stream of the sintering stage and the Exhaust air flow of the cooling stage from the clinker cooler separately or together in a fueled calcining stage used outside the sintering furnace for calcining the raw meal become.
  • the preheating stage usually consists of several one above the other arranged floating gas heat exchanger cyclones, the one after the other from the raw cement meal in combined cocurrent / countercurrent to the hot exhaust gas from the calcining stage or the rotary kiln be hiked through.
  • the precalcined in the calcining step Good material in the bottom cyclone of the cyclone levitation gas heat exchanger system separated from the hot gas and into the rotary kiln introduced. It is understood that the hot gas cyclones Cyclone suspension gas heat exchanger strand, especially the bottom one Cyclone with hot gas and hot flour at a temperature of e.g. B. 700 to 950 ° C comes into contact, a high mechanical, chemical and thermal stress and thus a high are exposed to thermochemical and abrasive wear. This This applies in particular to the central top of the cyclone separator protruding dip tube.
  • the invention is therefore based on the object for cement clinker production plants with cyclone levitation gas heat exchanger system to create a cyclone separator with segmented dip tube, in which the detachable immersion tube segment fastening is secure and is characterized by a long service life.
  • Characteristic of the cyclone separator according to the invention segmented dip tube, in which the dip tube segments at their upper ends with approximately radially arranged bolts the cyclone ceiling or with the cyclone gas exhaust line detachably connected is that the bolts are in around the dip tube circumference distributed spacers arranged outward (i.e. radial outside) at least one window-like opening for access to ambient air as a cooling medium for the immersion pipe segment attachment exhibit.
  • the bolts from the inside of the dip tube acting high temperatures in hot gas cyclones in the lower Area of a cyclone levitation gas heat exchanger system Cement clinker production plant can easily be about 900 ° C can, through the window-like openings of the spacers can easily discharge accessible ambient air as cooling air. It would also be possible to use the interior of the spacers Screw bolts through the window-like openings To provide fans or the like with forced ventilation as well possibly also with a feed and discharge even for a liquid Cooling medium.
  • the dip tube segments at the upper end an outwardly protruding one have a hook-shaped projection in cross section with which the dip tube segments engage in a web that extends from the Inside of the spacers extends upwards.
  • a total of four dip tube segments can according to a further feature of the invention in Crossing joint area in which two adjacent and adjoin two immersion tube segments arranged underneath, one that overlaps the intersection joint area on one side of the segments Holding plate can be arranged with four cross bolts through four corresponding holes in the four adjacent corners the dip tube segments are inserted, then on the four cross bolts inserted through to secure the Holding plate to be attached.
  • Figure 1 shows a section of a cyclone separator from the cyclone ceiling 10 provided with a refractory lining 11 on the inside is.
  • Hot gas and raw cement powder flow tangentially into the cyclone a plant for the production of cement clinker.
  • a dip tube protrudes centrally from above into the cyclone separator into it, which is composed of a multitude of segments and is suspended from the cyclone ceiling 10.
  • Figure 2 are two side by side arranged dip tube segments 12 and 13 to see which below, in turn, the further dip tube segments 14 and 15 etc. are attached.
  • From the cyclone ceiling 10 goes up centrally the gas discharge line equipped with a refractory lining 16 on the inside 17 onwards.
  • the dip tube segments 12, 13 etc. of the uppermost around the dip tube circumference distributed row have an outwardly angular protruding Projection 18 with which the dip tube segments in engage a web 19 extending from the inside of spacers 20 extends upwards.
  • the spacers 20 are around Dip tube circumference distributed on the cyclone ceiling 10, on the Gas line 17 attached and arranged approximately radially to the dip tube center. In the spacer bushes 20 there is an approximately radially arranged one Screw 21 arranged with which the dip tube segment 12 releasably connected to the insulated gas exhaust line 17 is.
  • dip tube segments 12 etc. are first by means of their hook-shaped projections 18 in the spacers 20 or their webs 19 hooked, causing the weight the segments are discontinued. Then the segments aligned and screwed.
  • the spacers distributed around the circumference of the immersion tube 20, in which the bolts 21 are arranged each have at least one outwardly window-like opening 22 for Access of ambient air as a cooling medium for the immersion pipe segment fastening.
  • the bolts 21 can high temperatures from the inside of the dip tube discharge to the outside air.
  • the Head of the bolts 21, which on the inside of the dip tube a corresponding recess of the dip tube segment 12 etc. and is arranged in the spacer 20, each by a Cover 23 is covered, the releasable attachment of the dip tube segments protects against high thermochemical stress. After assembly, the cover 23 can still be sewn by a tack weld be secured on the dip tube segment 12, etc. In any case is the dip tube segment attachment according to the invention by a marked long service life.
  • the intersection joint area arranged on one side of the segments covering holding plate 29 be with four cross bolts 30, 31, 32, 33 which are corresponding by four Holes in the four adjacent corners of the Dip tube segments are inserted, with the inserted through four cross bolts cross bolts 34, 35 for securing the holding plate 29 are attached.
  • the crossbars 34, 35 can be drawn as shown be arranged vertically, but also horizontally or diagonally.
  • the outer contour of the holding plate 29 can be square, square, round etc. be, and it can also have a central recess 36, z. B. a round hole, which saves weight on the holding plate 29 contributes.
  • the bottom row of the dip tube segments is expedient below stabilized only with crossbars 37.
