Description
Ofen zum Verkoken von kohlenstoffhaltigem Gut Die Erfindung betrifft einen Ofen zum Verkoken von kohlenstoffhaltigem Gut sowie zum Glühen von anderem Gut, in dem die Glühhitze in dem Gut selbst durch elektrischen Strom erzeugt wird und bei dem das Gut nacheinander durch eine Vorwärmzone, eine durch Stromdurchgang erhitzte Verkokungs- oder Glühzone und weiter durch eine Abkühlzone geführt wird, wobei in entgegengesetzter Richtung ein Gasstrom durch das Gut getrieben wird zwecks Ausnutzung der in der Abkühlzone abgegebenen Wärme zur Vorwärmung des in die Vorwärmzone eintretenden Gutes.Furnace for coking carbonaceous material The invention relates to a furnace for coking carbonaceous material as well as for annealing other Good, in which the glowing heat in the good itself is generated by electrical current and in which the goods are successively passed through a preheating zone, one through the passage of electricity heated coking or annealing zone and further through a cooling zone, whereby in the opposite direction a gas flow is driven through the material for the purpose Utilization of the heat given off in the cooling zone to preheat the in the preheating zone occurring good.
Um zu verhindern, daß die in der Abkühlzone auf etwa 80o` angewärmten Gase, deren Temperatur alsa die Endtemperatur in der Glühzone von etwa looo bis 140o° C bei weitem nicht erreicht, die Temperatur in der Glühzone in unzweckmäßiger Weise herabsetzen, sind gemäß der 'Erfindung in der Ofenwandung in Höhe der Glühzone Gaskanäle angeordnet, durch die, die in' der Abkühlzone erwärmten Gase um die Glühzone herum in die Vorwärmzone geführt werden können. Gleichzeitig mit der Verhinderung einer unzweckmäßigen Temperaturverringerung in der Glühzone wird hierbei eine erhebliche Entlastung des die Gase durch den Ofen drückenden Ventilators erreicht.To prevent the ones in the cooling zone from being warmed up to around 80o` Gases, the temperature of which is the final temperature in the annealing zone from about 10000 to 140o ° C is nowhere near reached, the temperature in the annealing zone in unsuitable Way, are according to the 'invention in the furnace wall at the level of the annealing zone Gas channels arranged through the, in 'the cooling zone heated gases around the annealing zone around into the preheating zone. Simultaneously with the prevention an inexpedient temperature reduction in the annealing zone becomes a considerable one Relief of the fan pushing the gases through the furnace is achieved.
Besondere Gasführungskanäle sind bei Gaserzeugern bekannt. Bei diesen Gaserzeugern haben sie aber die Aufgabe, Klargase getrennt von den Schmelzgasen abzuziehen, nicht aber zur Wärmeerzeugung durch einen Schachtofen gepreßte Gase um die Glühzone herumzuführen.Special gas ducts are known from gas generators. With these Gas generators, however, have the task of separating clear gases from the melt gases to be withdrawn, but not gases pressed through a shaft furnace to generate heat around the annealing zone.
Auf der Zeichnung ist ein Ausführungsbeispiel eines gemäß der Erfindung ausgeführten Ofens dargestellt. -Der Ofenschacht i ist in drei Zonen, und zwar die V orwärmzone A, die Glühzone B und die Abkühlzone C, unterteilt. Die zwischen der Glühzone und der Abkühlzone bestehende Vergrößerung des Profils braucht aber natürlich nicht unbedingt durchgeführt zu werden.The drawing shows an embodiment of a furnace designed according to the invention. The furnace shaft i is divided into three zones, namely the preheating zone A, the annealing zone B and the cooling zone C. Of course, the enlargement of the profile between the annealing zone and the cooling zone does not necessarily have to be carried out.
Am oberen und unteren Ende der Glühzone B sind Elektroden 2a und 2v zur Zu- und Abführung des Stromes angeordnet. Die Elektroden sind durch Stopfbüchsen 3 gasdicht in den Schacht eingeführt. Das Glühgut wird durch den Trichter q. eingebracht und durch die Vorrichtung 5 aus dem Ofen ausgetragen und schließlich durch einen geeigneten Apparat 6 entleert.Electrodes 2a and 2v for supplying and removing the current are arranged at the upper and lower ends of the annealing zone B. The electrodes are inserted gas-tight into the shaft through stuffing boxes 3. The material to be annealed is fed through the funnel q. introduced and discharged from the furnace by the device 5 and finally emptied by a suitable apparatus 6.
Durch den Ventilator 7 wird Gas durch die Rohrleitung 8 unten in die Austragvorrichtung 5 eingeführt, durch den Ofen nach oben gedrückt und oben aus der Vorwärmzone wieder abgezogen. Die Glühzone wird er-iindungsgemäß durch Kanäle 9 umgangen.The fan 7 is gas through the pipe 8 down into the Discharge device 5 inserted, pushed up through the oven and out at the top removed from the preheating zone. According to the invention, the annealing zone is made up of channels 9 bypassed.
Beim Betrieb des Ofens sinkt das Glühgut von der Vorwärmzone, in der es durch die dort eingeführten Gase bis auf Rotglut erwärmt wird, in die Glühzone, in der der Strom von den Zuführungselektroden auf das Glühgut übergeht und dort das Gut durch Ohmsche '\Värine erhitzt. Beim weiteren Absinken verläßt das Glühgut die Glühzone und gelangt in die Abkühlzone. Der kalte, durch den Ventilator 7 neu eingeblasene Gasstrom erwärmt sich in der Abkühlzone C. Der Hauptteil des Gasstromes tritt durch die Kanäle 9 von der Abkühlzone in die V orwärmzone und gibt dort seine Wärme an das kalte Glühgut ab.When the furnace is in operation, the material to be annealed sinks from the preheating zone in which it is heated to red heat by the gases introduced there, in the glow zone, in which the current passes from the supply electrodes to the annealing material and there the material is heated by Ohmsche '\ Värine. The annealing material leaves when it continues to sink the annealing zone and gets into the cooling zone. The cold one, thanks to the fan 7, new blown gas stream is heated in the cooling zone C. The main part of the gas stream passes through the channels 9 from the cooling zone into the preheating zone and is there Heat to the cold annealing material.
Der beschriebene elektrische Ofen kann sowohl zum Verkoken von Kokskohle als auch zum Glühen irgendwelchen anderen leitenden Gutes verwendet werden. Er eignet sich besonders gut zum Glühen des in der Elektrodenindustrie verwendeten Petrolk:okses zum Austreiben der in diesem enthaltenen flüchtigen Bestandteile und der Feuchtigkeit.The electric furnace described can be used for coking coking coal as well as for glowing any other conductive good. He is suitable particularly good for glowing the petrol k: okses used in the electrode industry to drive off the volatile constituents and moisture contained in it.
