Description

Die Erfindung betrifft ein Verfahren zur Kühlung von heißen Schütt- gütern, wie z.B. Koks, Klinker, Sinter in einem Kühler, insbesondere zur Entlastung des Gaskühlkreislaufes und eine Einrichtung zur Durchführung des Verfahrens. Es ist bekannt, heiße Schüttgüter im Gasstrom zu kühlen, wobei das Kühlgas soweit aufgeheizt wurde, daß beim Kühlen des Kühlgases die Kühlflächen der Gefahr einer Überhitzung ausgesetzt wurden.The invention relates to a method for cooling hot bulk - goods, such as coke, clinker sintered in a cooler, in particular for the discharge of the gas cooling circuit and a device for carrying out the method. It is known to cool hot bulk goods in the gas stream, the cooling gas being heated up to such an extent that the cooling surfaces were exposed to the risk of overheating when the cooling gas was cooled.

Die Erfindung hat es sich zur Aufgabe gestellt den Kühlprozeß zu vereinfachen und die Kühlung des Schüttgutes durch ein Kühlgas, durch die Abfuhr der Strahlungswärme möglichst weitgehend zu ersetzen.The object of the invention is to simplify the cooling process and to replace the cooling of the bulk material by a cooling gas as far as possible by removing the radiant heat.

Das erfindungsgemäße Verfahren ist dadurch gekennzeichnet, daß die Oberfläche der ausgebreiteten Schüttung im Kühler ständig mit heißem Schüttgut beaufschlagt, bzw. vom abgekühlten Schüttgut befreit wird, wobei die von der Oberfläche ausgehende, intensive Wärmestrahlung über Strahlungskühlflächen abgeführt wird und daß das teilweise abgekühlte Schüttgut während der Abstrahlung, oder insbesondere anschließend an sie, in einem strömenden Gasstrom weiter abgekühlt wird. Weitere wesentliche Verfahrensmerkmale sind in den Verfahrensansprüchen 2 und 3 gekennzeichnet.The process according to the invention is characterized in that hot bulk material is constantly applied to the surface of the spread bulk in the cooler, or is freed from the cooled bulk material, the intense heat radiation emanating from the surface being dissipated via radiation cooling surfaces and in that the partially cooled bulk material is removed during the Radiation, or in particular following it, is further cooled in a flowing gas stream. Further essential process features are characterized in process claims 2 and 3.

Die-erfindungsgemäße Einrichtung zur Durchführung des Verfahrens ist dadurch gekennzeichnet, daß in einem Kühler, welchen das zu behandelnde Schüttgut durchwandert, oberhalb der freien Schüttgutoberfläche dieser zugewendet eine Strahlungskühlfläche vorgesehen ist und daß in Flußrichtung des Schüttgutes unterhalb dieser Strahlungskühlfläche eine Gaskühlung, insbesondere mittels im Kreislauf geführtes Gas vorgesehen ist, wobei der Austritt des Kühlgases aus dem Kühler im Bereich unterhalb der Strahlungskühlfläche vorzugsweise durch eine Schüttgutschicht, von dieser getrennt angeordnet ist.The device according to the invention for carrying out the method is characterized in that in a cooler through which the bulk material to be treated passes, a radiation cooling surface is provided above the free bulk material surface and that in the direction of flow of the bulk material below this radiation Cooling surface gas cooling is provided, in particular by means of gas circulated, the outlet of the cooling gas from the cooler in the area below the radiation cooling surface is preferably arranged separately from this by a bulk material layer.

Die Erfindung ist in den Figuren 1-5 beispielsweise und schematisch dargestellt. Es zeigen

  • Fig.1 einen kegelförmigen Bunker
  • Fig.2 einen 2-teiligen Kühlbunker
  • Fig. 3 einen Kühlbunker ohne Gaskühlung
  • Fig.4 einen Kühlbunker hinter einem Drehrohrofen
  • Fig. 5 einen rinnenförmigen Tunnelofen mit einer Kühlsektion.
The invention is shown schematically, for example, in FIGS. 1-5. Show it
  • Fig.1 a conical bunker
  • Fig.2 a 2-part cooling bunker
  • Fig. 3 shows a cooling bunker without gas cooling
  • 4 shows a cooling bunker behind a rotary kiln
  • Fig. 5 shows a trough-shaped tunnel furnace with a cooling section.

In Fig.1 ist ein kegelförmiger Bunker dargestellt, bei dem das Schüttgut über einen zentralen Trichter 12 eingebracht wird. Wird an der Unterseite des kegeligen Kühlers Schüttgut kontinuierlich abgezogen, so senkt sich die Schüttgutoberfläche 3 innerhalb des Kühlers und frisches heißes Schüttgut wird aus dem zentralen Trichter 12 im Kühler aufgeschüttet, sodaß die Strahlungsheizflächen 4 durch die intensive Wärmebestrahlung des Schüttgutes beheizt werden. Zur Intensivierung der Kühlung ist darüber hinaus eine Gaskühlung vorgesehen, mittels welcher ein kaltes Kühlgas über das Gebläse 13 einer Gasverteileinrichtung 14 dem Schüttgut zugeführt wird. Das Kühlgas strömt durch die Schichten des Schüttgutes hin nach oben, wird im ringförmigem Raum 15 oberhalb der Schüttgutoberfläche gesammelt und über den Austritt 6 der Rückkühleinrichtung 16 zugeführt.1 shows a conical bunker, in which the bulk material is introduced via a central funnel 12. If bulk material is continuously drawn off on the underside of the conical cooler, the bulk material surface 3 lowers within the cooler and fresh hot bulk material is poured out of the central funnel 12 in the cooler, so that the radiant heating surfaces 4 are heated by the intensive heat radiation of the bulk material. To intensify the cooling, gas cooling is also provided, by means of which a cold cooling gas is fed to the bulk material via the blower 13 of a gas distribution device 14. The cooling gas flows upwards through the layers of the bulk material, is collected in the annular space 15 above the bulk material surface and is fed to the recooling device 16 via the outlet 6.

In Fig.2 ist eine Konstruktionsvariante zu Fig.1 dargestellt, bei welcher die Gasbehandlungszone 10 mit der Gaskühlung 5 getrennt von einer Schüttgutvorlage 7 ausgebildet ist, in welches das heiße Schüttgut allein durch die Strahlungsheizfläche 4 abgekühlt wird. Durch diese Maßnahme wird erreicht, daß das Kühlgas bei seinem Austritt 6 aus der Gasbehandlungszone eine bedeutend geringere Temperatur aufweist, sodaß Überhitzungen in der Gasleitung mit Sicherheit vermieden werden können. Auch bei dieser Ausführung kann in der Nähe des Gasaustrittes 6 eine Strahlungsheizfläche 17 ähnlich jener mit dem Bezugszeichen 4 vorgesehen werden, wodurch das Kühlgas weiter entlastet wird.2 shows a construction variant of FIG. 1, in which the gas treatment zone 10 with the gas cooling 5 is formed separately from a bulk material receiver 7, into which the hot bulk material is cooled solely by the radiant heating surface 4. This measure ensures that the cooling gas at its exit 6 from the gas treatment zone has a significantly lower temperature, so that overheating in the gas line can be avoided with certainty. In this embodiment too, a radiant heating surface 17 can be located in the vicinity of the gas outlet 6 similar to that provided with the reference numeral 4, whereby the cooling gas is further relieved.

In Fig.3 ist in größerem Maßstab die Schüttgutvorlage 7 dargestellt, bei der die Kühlung so stark ist, daß das Schüttgut soweit abgekühlt wird, daß eine problemlose Lagerung oder ein bequemer Abtransport möglich ist. Die in den Fig.1-3 dargestellten Kühler eignen sich besonders zur Kühlung von glühendem Koks, Klinker oder auch Sinter.In Figure 3, the bulk material template 7 is shown on a larger scale, in which the cooling is so strong that the bulk material is cooled so far that problem-free storage or convenient removal is possible. The coolers shown in Fig. 1-3 are particularly suitable for cooling red-hot coke, clinker or sinter.

In Fig.4 ist eine Kühleinrichtung für heiße kohlenstoffhältige Schüttgüter dargestellt, die in einem Drehrohrofen 17 erhitzt wurden. Beim Austritt des Schüttgutes aus dem Drehrohrofen 17, in den Kühler 1, ist eine Strahlungsheizfläche 4 vorgesehen, über welche die von der Oberfläche 3 des Schüttgutes ausgehende Wärmestrahlung kontinuierlich abgeführt wird. Das heiße Schüttgut wird dabei soweit abgekühlt, daß es in der Gasbehandlungszone, auch wenn es von Luft durchströmt wird, nicht weiter erhitzt, bzw. verbrennt und seine Wärme an das Gas bzw. die Luft abgibt, welche über die Leitung 18 in den Drehrohrofen abgegeben wird und dort zur Verbrennung eines Teiles, des im Schüttgut enthaltenen Kohlenstoffes Verwendung findet.4 shows a cooling device for hot carbon-containing bulk goods which have been heated in a rotary kiln 17. When the bulk material exits from the rotary kiln 17, into the cooler 1, a radiant heating surface 4 is provided, via which the heat radiation emanating from the surface 3 of the bulk material is continuously dissipated. The hot bulk material is cooled to such an extent that it does not continue to heat or burn in the gas treatment zone, even if air flows through it, and gives off its heat to the gas or air, which is emitted via line 18 into the rotary kiln and is used there for the combustion of a part of the carbon contained in the bulk material.

In Fig.5 ist die Anwendung der Erfindung bei einer Ringherdverkokungsanlage dargestellt. Das zu verkokende Material, wird gemäß Pfeil 19 dem Ringherd aufgegeben, in der Verkokungsanlage 20 erhitzt und verkokt und schließlich dem Kühler 1 zugeführt, in welchem jeweils die oberste Schicht durch die Strahlungsheizfläche 4 abgekühlt wird. Die oberste Schicht wird gemäß Pfeil 21 nach erfolgter Abkühlung durch eine Kratzeinrichtung entfernt, wobei die mittlere Schicht der intensiven Kühlung durch die Strahlungsheizfläche ausgesetzt wird, die ebenfalls nach erfolgter Auskühlung entfernt wird. Im letzten Teil des Kühlers wird dann die unterste Schicht 23 abgekühlt und anschließend vom Herd entfernt.5 shows the use of the invention in a ring hearth coking plant. The material to be coked is given to the ring hearth according to arrow 19, heated and coked in the coking plant 20 and finally fed to the cooler 1, in which the top layer is cooled by the radiant heating surface 4. The top layer is removed according to arrow 21 after cooling by a scraping device, the middle layer being exposed to intensive cooling by the radiant heating surface, which is also removed after cooling. In the last part of the cooler, the bottom layer 23 is then cooled and then removed from the stove.
