Die Erfindung betrifft einen Zyklonabscheider, insbesondere für die direkte Wärmeübertragung von den heißen Abgasen einer Drehrohrofen-Zyklonschwebegas-Wärmetauscher-Anlage zur Zementklinkerherstellung auf das Zementrohmehl, mit tangentialer Zuführung von Gas und Rohmehl, Gutaustrag im unteren Zyklonbereich und mit einem zentral von oben in den Zyklonabscheider hineinragenden und an der Zyklondecke aufgehängten, aus mehreren Segmenten zusammengesetzten Tauchrohr für die Gasabführung, wobei die Tauchrohrsegmente an ihrem oberen Ende durch Schraubenbolzen mit der durch Feuerfestauskleidung isolierten Gasabzugsleitung lösbar verbunden sind.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.
Bei Anlagen zur Herstellung von Zementklinker aus Zementrohmehl wird das Rohmehl durch Vorwärmen, Calcinieren, Sintern und Kühlen thermisch behandelt, wobei der Abgasstrom der Sinterstufe und der Abluftstrom der Kühlstufe aus dem Klinkerkühler getrennt oder gemeinsam in einer mit Brennstoff versorgten Calcinierstufe noch außerhalb des Sinterofens zur Calcination des Rohmehls genutzt werden. Die Vorwärmstufe besteht in der Regel aus mehreren übereinander angeordneten Schwebegas-Wärmetauscherzyklonen, die nacheinander vom Zementrohmehl im kombinierten Gleich-/Gegenstrom zum heißen Abgas der Calcinierstufe bzw. des Drehrohrofens durchwandert werden. Dabei wird das in der Calcinierstufe vorcalcinierte Gutmaterial im untersten Zyklon des Zyklonschwebegas-Wärmetauschersystems vom Heißgas abgetrennt und in den Drehrohrofen eingeführt. Es versteht sich, daß die Heißgaszyklone des Zyklonschwebegas-Wärmetauscherstranges, insbesondere der unterste Zyklon, der mit Heißgas und Heißmehl einer Temperatur von z. B. 700 bis 950°C in Berührung kommt, einer hohen mechanischen, chemischen und thermischen Beanspruchung und damit einem hohen thermochemischen und abrasiven Verschleiß ausgesetzt sind. Dies gilt insbesondere für das zentral von oben in den Zyklonabscheider hineinragende Tauchrohr.In plants for the production of cement clinker from raw cement flour 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.
Es ist daher schon bekannt (DE-C-32 28 902), bei einem diesen hohen Beanspruchungen ausgesetzten Zyklonabscheider das Tauchrohr aus mehreren Segmenten zusammenzusetzen und die Tauchrohrsegmente mittels hakenförmiger Ausbildung an der Zyklondecke aufzuhängen oder vermittels radial angeordneter Schraubenbolzen mit der durch eine Feuerfestauskleidung isolierten Gasabzugsleitung des Zyklons lösbar zu verbinden, um Verformungen am Tauchrohrmantel selbst bei hohen thermischen Wechselbelastungen zu vermeiden und im Verschleißfall einzelne Tauchrohrsegmente mit verhältnismäßig geringem Zeit- und Arbeitsaufwand erneuern zu können. Dabei waren aber die Schraubverbindungen der Tauchrohrsegmente nicht gegen die thermochemischen Belastungen geschützt, mit der Folge, daß die Gefahr nicht ausgeschlossen war, daß sich die Schraubverbindung nach einer gewissen Zeit löste, wonach bei fehlender weiterer Sicherung das betreffende Tauchrohrsegment nach unten in den Zyklonabscheider fallen kann.It is therefore already known (DE-C-32 28 902), with a high one Cyclone separators subject the dip tube to stress composed of several segments and the dip tube segments hang from the cyclone ceiling using a hook-shaped design or by means of radially arranged screw bolts the gas discharge line of the gas pipe, insulated by a refractory lining Detachable connection of cyclones to prevent deformation of the dip tube jacket to avoid even with high thermal alternating loads and in the event of wear, individual dip tube segments with relative to be able to renew with little time and effort. Were there but not the screw connections of the dip tube segments protected the thermochemical loads, with the result that the Danger was not excluded that the screw connection after a certain time resolved what after missing further backup the relevant dip tube segment down into the cyclone separator can fall.
Der Erfindung liegt daher die Aufgabe zu Grunde, für Zementklinkerherstellungsanlagen mit Zyklonschwebegas-Wärmetauschersystem einen Zyklonabscheider mit segmentiertem Tauchrohr zu schaffen, bei dem die lösbare Tauchrohrsegment-Befestigung sicher ist und sich durch eine hohe Standzeit auszeichnet. 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.

Mit dieser Konstruktion wird erreicht, daß die Schraubenbolzen die von der Tauchrohrinnenseite her einwirkenden hohen Temperaturen, die bei Heißgas-Zyklonen im unteren Bereich eines Zyklonschwebegas-Wärmetauschersystems einer Zementklinkerherstellungsanlage ohne weiteres etwa 900°C betragen können, auf die durch die fensterartigen Öffnungen der Distanzbuchsen zugängliche Umgebungsluft als Kühlluft gut ableiten können. Es wäre auch möglich, den Innenraum der Distanzbuchsen mit den Schraubenbolzen durch die fensterartigen Öffnungen hindurch mittels Gebläse oder dergleichen mit Zwangsbelüftung zu versehen sowie ggf. auch mit einer Zuführung und Abführung sogar für ein flüssiges Kühlmedium.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. With this construction it is achieved that 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.
