Description

Drehrohrofen, bei dem der Brenngut-Schlamm oder -Staub im Gleichstrom mit den Brenngasen eingespritzt wird Das Hauptpatent 421 551 betrifft ein Verfahren und eine Vorrichtung zum Einbringen von Schlamm in Drehrohröfen, darin bestehend, daß der Schlamm mittels entsprechender Düsen und unter starkem Druck vom Auslaufende des Ofens her eingespritzt wird, den Ofen gleichgerichtet mit den Feuergasen in geschlossenem Strahl durchläuft und etwa am Einlaufteil in einem feinen Sprühregen niederfällt.Rotary kiln in which the sludge or dust to be fired is in direct current is injected with the fuel gases. The main patent 421 551 relates to a method and a device for introducing sludge into rotary kilns, consisting therein that the sludge by means of appropriate nozzles and under strong pressure from the outlet end of the furnace is injected, the furnace is rectified with the fire gases in runs through a closed jet and about the inlet part in a fine spray falls down.

Das Zusatzpatent besteht darin, daß bei der vorstehend gekennzeichneten Vorrichtung im Ofenraum ein an sich bekanntes Bündel von Ketten, Drähten, Drahtgewebe oder ähnliche Hindernisse eingebaut sind, gegen die der Sprühregen geführt wird. An diese Hindernisse geben die Heizgase ihre Hitze ab. Durch den Schlamm- oder Staubstrom werden die Hindernisse gekühlt, so daß ein Erglühen und Abzundern der getroffenen Teile vermieden wird. und durch das Überziehen mit Schlamm und Staub tritt ein besonderer Schutz der Hindernisse gegen Zerstörung durch die Flitze ein.The additional patent consists in that in the case of the above Device in the furnace chamber a known bundle of chains, wires, wire mesh or similar obstacles are installed against which the spray is directed. The heating gases give off their heat at these obstacles. By the stream of mud or dust the obstacles are cooled, so that a glowing and scaling of the struck Parts is avoided. and when it is covered with mud and dust, a special one occurs Protection of the obstacles against destruction by the streak.

Die Zeichnung stellt zwei Ausführungsbeispiele dar.The drawing shows two exemplary embodiments.

Fig. i zeigt eine Anordnung, bei der an dem einen Ende des Drehrohrofensa der Brennstoff und ,gegebenenfalls die Verbrennungsluft durch eine Düse c, das Brenngut durch eine von dieser umgebene zentrale Düse beingeführt wird und die Verbrennungsgase den Ofen, nachdem sie ihn in seiner lyanzen Länge durchströmt haben, am Centgegengesetzten Ende durch den Schornstein d verlassen. Den Ofenquerschnitt füllen Ketten h ,aus, die die vorstehend geschilderte Wirkung haben.Fig. I shows an arrangement in which at one end of the rotary kiln a the fuel and, if necessary, the combustion air through a nozzle c, the material to be fired is guided through a central nozzle surrounded by this and the combustion gases the furnace, after it has flowed through it in its full length, on the opposite side of the cent Leave the end through the chimney d. The cross-section of the furnace is filled with chains h, which have the effect described above.

Der Austritt des fertiggebrannten Gutes 6üdet ,an der Gaseintrittsseite bei e statt. Das Beispiel nach Fig. 2 zeigt eine Anordnung, bei der der Austritt der Verbrennungsgase durch den Abzug d an demselben Ofenende erfolgt, an dem durch die Düse b, die von der den Brennstoff zuführenden ringförmigen Düse c -umgeben ist, der Eintritt des schlämm. oder staubförmigen Brenngutes stattfindet. An derselben Seite erfolgt auch der Austritt des gebrannten Gutes durch die Entleerungsvorrichtung e. Die Ketten fz sind hier in einer besonderen Abteilung a1 des Ofens a angebracht.The exit of the finished product 6üdet takes place on the gas inlet side at e. The example according to FIG. 2 shows an arrangement in which the exit of the combustion gases takes place through the flue d at the same furnace end at which the slurry enters through the nozzle b, which is surrounded by the annular nozzle c that supplies the fuel. or dusty material to be fired takes place. On the same side, the fired material is also discharged through the emptying device e. The chains fz are attached here in a special compartment a1 of the furnace a.
