Description

Die Erfindung bezieht sich auf ein Verfahren zur Kühlung und Entstaubung von Koks nach Verlassen einer Kokstrockenkühlung sowie einen Tauchbehälter zur Durchführung des Verfahrens.The invention relates to a method for cooling and dedusting coke after leaving a dry coke cooling and an immersion tank for performing the method.

Aus der Voranmeldung P 34 29 292 ist ein Verfahren zur Entstaubung von trocken gekühltem Koks bekannt, bei dem im wesentlichen durch Einblasen von Luft der Feinstaub von den Koksstücken entfernt werden soll. Daneben soll durch geeignete mechanische Bewegung des Kokses der Staub von den Koksstücken gelöst werden. Die Möglichkeiten bei diesem Verfahren sind begrenzt, und es läßt sich nicht überall einsetzen.From prior application P 34 29 292 a method for dedusting dry-cooled coke is known, in which the fine dust is to be removed from the coke pieces essentially by blowing air. In addition, the dust should be released from the coke pieces by suitable mechanical movement of the coke. The possibilities with this method are limited and it cannot be used everywhere.

Aus dem Gebiet der Heißbrikettierung nach dem ancit--Verfahren (DE-OS 27 49 408) ist ein Verfahren zur Kühlung der ca. 500 °C heißen Briketts bekannt, bei dem diese über ein Förderband in eine Wassertauchung geleitet werden und nach einer Schlußkühlung verladen werden. Bei diesem ausschließlich für die Kühlung der Heißbriketts angewandten Verfahren hat das Wasserbad eine Temperatur von ca. 40 bis 50 °C und das Kreislaufwasser wird in Wärmetauschem zusätzlich gekühlt Das Problem der Staubentwicklung besteht bei den Briketts nichtFrom the field of hot briquetting according to the ancit method (DE-OS 27 49 4 08), a method for cooling the briquettes, which have a temperature of approximately 500 ° C., is known, in which they are passed into a water immersion via a conveyor belt and after final cooling be loaded. In this process, which is used exclusively for cooling the hot briquettes, the water bath has a temperature of approx. 40 to 50 ° C and the circulating water is additionally cooled in heat exchangers. The problem of dust development does not exist with the briquettes

Aufgabe der Erfindung ist es, ein wirksames Verfahren zur Entstaubung des trocken gekühlten Kokses vorzuschlagen, bei dem die aufwendigen Maßnahmen zur trockenen Entstaubung entfallen.The object of the invention is to propose an effective method for dedusting the dry-cooled coke, in which the complex measures for dry dedusting are omitted.

. Die erfindungsgemäße Lösung dieser Aufgabe besteht darin, daß der Koks mit einer Temperatur von ca. 150 bis 200 °C in einen Tauchbehäfter mit einer Flüssigkeitstemperatur von ca. 100 °C gegeben und vorzugsweise mit stufenlos regelbarer Geschwindigkeit aus dem Tauchbehäfter herausbefördert und dabei vom Feinstaub befreit wird.. The solution to this problem according to the invention is that the coke with a temperature of about 150 to 200 ° C in a dip tank with a liquid temperature of about 100 ° C and preferably conveyed out at an infinitely variable speed out of the dip tank and thereby freed from fine dust becomes.

Es hat sich gezeigt, daß bei einer Temperatur des Kokses von mindestens 150 °C beim Eintritt in das Wasserbad dieses auf einer Temperatur von ca. 100 °C gehalten werden kann, so daß auch der Koks nach kurzer Zeit das Wasserbad mit einer Temperatur von ca. 100 °C verläßt. Bei dieser. Austrittstemperatur des Kokses von ca. 100 °C ist gewährleistet, daß das beim Austrag aus dem Tauchbad mitgenommene Wasser anschließend weitgehend wieder verdampft.It has been shown that at a temperature of the coke of at least 150 ° C when entering the water bath, this can be kept at a temperature of about 100 ° C, so that the coke after a short time the water bath with a temperature of approx 100 ° C leaves. At this. Exit temperature of the coke of approx. 100 ° C ensures that the water taken out of the immersion bath afterwards largely evaporates again.

Es läßt sich erfindungsgemäß insbesondere der Wassergehalt des Kokses nach einer ausreichenden Ausdampfzeit auf einen Wassergehalt unter 5 %, vorzugsweise unter 3 %, dadurch einstellen, daß die Geschwindigkeit, mit der der Koks aus dem Tauchbehäfter gefördert wird, geregelt wird. Es hat sich nun gezeigt, daß eine Tauchzeit des Kokses von weniger als 3 Minuten, vorzugsweise sogar von 1 bis 20 Sekunden, besonders günstig ist. um einen geringen und auch gleichmäßigen Wassergehaft des Kokses zu erhalten.According to the invention, in particular the water content of the coke can be adjusted to a water content below 5%, preferably below 3%, after a sufficient evaporation time by regulating the speed at which the coke is conveyed out of the immersion container. It has now been found that a coke immersion time of less than 3 minutes, preferably even from 1 to 20 seconds, is particularly favorable. to maintain a low and even water content of the coke.

Als wichtigster Vorteil des erfindungsgemäßen Verfahrens ist die Tatsache anzusehen, daß in dem Tauchbehälter alle Feinstäube aus den Koksstücken herausgetrennt und zunächst vom Wasser aufgenommen und anschließend mit dem Kettenförderer abtransportiert werden.The most important advantage of the method according to the invention is the fact that all fine dust is separated from the coke pieces in the immersion container and is first taken up by the water and then transported away with the chain conveyor.

Die auf der Wasseroberfläche schwimmenden Koksstäube werden erfindungsgemäß durch Aufsprühen von Kreislaufwasser und/oder Frischwasser in Kokstransportrichtung und/oder zu Sieb- und/oder Filtereinrichtungen hin gespült. Diese Sieb- und Filtereinrichtungen werden dann in an sich bekannter Weise abgereinigt. Der Koksgrus und die kleineren Koksstücke, die am Boden des Kettenförderers sich absetzen, werden beim Rücklauf des Kettenförderers außerhalb des Wasserbades abgetrennt, wobei gegebenenfalls der noch am Kettenförderer anhaftende Koksgrus vor Eintritt in den Tauchbehälter abgespült wird.The coke dusts floating on the water surface are rinsed according to the invention by spraying on circulating water and / or fresh water in the coke transport direction and / or towards sieving and / or filtering devices. These sieve and filter devices are then cleaned in a manner known per se. The coke breeze and the smaller pieces of coke that settle at the bottom of the chain conveyor are separated when the chain conveyor returns outside the water bath, with the coke breeze still adhering to the chain conveyor being rinsed off before entering the immersion container.

Auch der Koks soll beim Verlassen des Tauchbehälters zum Abspülen der oberflächlich anhaftenden Feinstäube zusätzlich mit geringen Mengen an Wasser beaufschlagt werden.When leaving the immersion tank, the coke should also be charged with small amounts of water to rinse off the fine dust adhering to the surface.

Das aus dem Tauchbehälter und evtl. der Auffangwanne unterhalb des Tauchbehälters abgezogene Wasser wird nach einer eventuellen zusätzlichen Reinigung im Kreislauf zurückgegeben.The water drawn out of the immersion tank and possibly the drip pan below the immersion tank is returned to the circuit after any additional cleaning.

Zur Verringerung der Korrosionsgefahr und eventuell als Staubbindemittel hat es sich als günstig erwiesen, dem Wasser des Tauchbehälters in geringen Mengen z. B. Kalkmilch oder ähnliche Substanzen zuzugeben. Der Koks kann auch beim Verlassen des Tauchbehälters mit einem Staubbindemittel z. B. aus öligen oder teerhaltigen Stoffen besprüht werden.To reduce the risk of corrosion and possibly as a dust-binding agent, it has proven to be advantageous to add small amounts of water to the immersion tank, e.g. B. add milk of lime or similar substances. The coke can also be used when leaving the immersion tank with a dust-binding agent, e.g. B. sprayed from oily or tar-containing substances.

Zur Durchführung des Verfahrens wird ein Tauchbehälter vorgeschlagen, der aus einem kastenförmigen, offenen Behälter mit kontinuierlich umlaufendem Kettenförderer besteht, wobei der Rücklauf des Kettenförderers außerhalb des Wasserbades im Freien unter dem Behälterboden angeordnet ist Zum Auffangen des Koksgruses und der kleineren Koksstücke ist dabei zweckmäßigerweise unterhalb des Tauchbehälters eine Auffangwanne mit Wasserablauf vorgesehen. Der Tauchbehälter besitzt zur Abtrennung der feinen Schwebestoffe aus dem Wasser einen Wasserüberlauf mit Sieb- und Filtereinrichtungen und zugehörigen Reinigungsgeräten. Diese Siebe und Filter sind zweckmäßigerweise im Bereich des Austrages des Kokses, vorzugsweise in den Seitenwänden des Tauchbehälters angeordnetTo carry out the method, a submersible container is proposed, which consists of a box-shaped, open container with a continuously rotating chain conveyor, the return of the chain conveyor being arranged outside the water bath in the open under the container bottom. To catch the coke bump and the smaller pieces of coke is expediently below the Immersion tank provided a drip pan with water drain. To separate the fine suspended matter from the water, the immersion tank has a water overflow with sieve and filter devices and associated cleaning devices. These screens and filters are expediently arranged in the area of the discharge of the coke, preferably in the side walls of the immersion container

Zur Kondensation der aus dem Tauchbehälter aufsteigenden Dampfschwaden kann schließlich die Haube des Tauchbehälters oder auch der Austrittsquerschnitt eine indirekte Wasserkühlung besitzen. Damit wird vor allem der Wasserverlust durch Verdampfung gering gehalten.Finally, to condense the steam vapors rising from the immersion tank, the hood of the immersion tank or the outlet cross section can have indirect water cooling. Above all, this keeps water loss through evaporation low.
