Abstract

1. Equipment for cooling gas-permeable loose material, especially hot coke, consisting of a primary chamber and a cooling chamber located underneath the latter, characterized in that the primary chamber and the cooling chamber are constructed as two bunkers (10 and 1) which are mutually independent statically and which are connected to one another in a gas-tight manner by means of a compensator (15) and are supported by a common or separate frame structure (9).

Description

Die Erfindung betrifft eine Vorrichtung zur Kühlung von gasdurchlässigem Schüttgut, insbesondere von heißem Koks, bestehend aus einer Vorkammer und einer darunter angeordneten Kühlkammer.The invention relates to a device for cooling gas-permeable bulk material, in particular hot coke, consisting of a prechamber and a cooling chamber arranged underneath.

Vorrichtungen der genannten Art sind in unterschiedlichen Ausführungsformen bekannt und werden insbesondere für die sogenannte Kokstrockenkühlung eingesetzt. Bisher wurden derartige Vorrichtungen jedoch normalerweise so ausgeführt, daß die Vorkammer und die Kühlkammer bzw. Kühlzone statisch und meist auch baulich eine Einheit bildeten. Die Vorkammer dient dabei der Bevorratung mit dem heißen Schüttgut, während der Kühlvorgang im wesentlichen in der Kühlkammer stattfindet, wobei das heiße Schüttgut im direkten Wärmeaustausch mit einem gasförmigen Kühlmedium abgekühlt wird. Während des Kühlvorganges bilden sich jedoch innerhalb der Vorrichtung Wärmezonen mit unterschiedlichem Temperaturniveau aus, die das Wärmeverhalten der verwendeten Baumaterialien, insbesondere der keramischen feuerfesten Materialien, unterschiedlich beeinflussen und die zu Beschädigungen bzw. Zerstörungen insbesondere des inneren Mauerwerkes führen können. Bisher konnten die sich daraus ergebenden Probleme nur mit einem verhältnismäßig hohen baulichen und konstruktiven Aufwand beherrscht werden.Devices of the type mentioned are known in different embodiments and are used in particular for so-called dry coke cooling. So far, however, such devices have normally been designed such that the prechamber and the cooling chamber or cooling zone form a unit statically and usually structurally. The prechamber serves to store the hot bulk material, while the cooling process takes place essentially in the cooling chamber, the hot bulk material being cooled in direct heat exchange with a gaseous cooling medium. During the cooling process, however, heat zones with different temperature levels form within the device, which influence the thermal behavior of the building materials used, in particular the ceramic refractory materials, and which can lead to damage or destruction, in particular of the inner masonry. So far, the resulting problems could only be mastered with a relatively high level of structural and constructive effort.

So ist beispielsweise aus der DE-OS-3 004 502 eine Vorrichtung für die Kokstrockenkühlung bekannt, deren Oberteil und Unterteil durch eine Gleitfuge miteinander in Verbindung stehen. Dadurch soll dem unterschiedlichen Dehnungsverhalten von Vorkammer und Kühlkammer während des Betriebes der Vorrichtung Rechnung getragen werden. Die Belastung der Kühlkammer durch das Vorkammergewicht bleibt bei dieser Konstruktion jedoch unverändert, und es ist nicht auszuschließen, daß durch nicht intakte Dehnfugen Schäden, vor allem am feuerfesten Mauerwerk, auftreten.For example, from DE-OS-3 004 502 a device for drying coke dry is known, the upper part and lower part of which are connected by a sliding joint. This should take into account the different expansion behavior of the prechamber and cooling chamber during operation of the device. The load on the cooling chamber due to the prechamber weight remains unchanged in this construction, and it cannot be ruled out that damage, especially to the refractory masonry, may occur due to intact expansion joints.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, bei der die vorstehend geschilderten Probleme auf möglichst einfache Art und Weise gelöst werden, und die im Hinblick auf ihre möglichen Ausführungsformen eine hohe Flexibilität aufweist.The invention is therefore based on the object of providing a device of the type mentioned at the outset in which the problems outlined above are solved in the simplest possible manner and which has a high degree of flexibility with regard to its possible embodiments.

Die der Lösung dieser Aufgabe dienende Vorrichtung ist erfindungsgemäß dadurch gekennzeichnet, daß die Vorkammer und die Kühlkammer als zwei statisch voneinander unabhängige Bunker ausgeführt werden, die mittels eines Kompensators gasdicht miteinander verbunden sind und von einer gemeinsamen oder getrennten Gerüstkonstruktion gehalten werden.The device serving to achieve this object is characterized according to the invention in that the prechamber and the cooling chamber are designed as two statically independent bunkers which are connected to one another in a gastight manner by means of a compensator and are held by a common or separate scaffold construction.

Das heißt, bei der erfindungsgemäßen Konstruktion werden Vorkammer und Kühlkammer statisch so voneinander getrennt, daß sie zwei separate und baulich eigenständige Einheiten bilden, die den unterschiedlichen Temperaturbedingungen in Vorkammer und Kühlkammer einfacher und besser angepaßt werden können. Gleichzeitig können dadurch beide Einheiten konstruktiv einfach und verfahrenstechnisch optimal auf die jeweils geforderte Anwendungsgröße ausgelegt werden. Das gilt auch im Hinblick auf die äußere Formgebung, so können beispielsweise beide Einheiten einen runden oder einen eckigen Querschnitt aufweisen.That is, in the construction according to the invention, the prechamber and the cooling chamber are statically separated from one another in such a way that they form two separate and structurally independent units which can be more easily and better adapted to the different temperature conditions in the prechamber and the cooling chamber. At the same time, both units can be designed in a structurally simple and process-technically optimal manner for the required application size. This also applies to the external shape, for example both units can have a round or an angular cross-section.

Weitere Einzelheiten der erfindungsgemäßen Vorrichtung ergeben sich aus den vorliegenden Unteransprüchen sowie aus dem Ausführungsbeispiel, das nachfolgend an Hand der Abbildung erläutert werden soll.Further details of the device according to the invention result from the present subclaims and from the exemplary embodiment which is to be explained below with reference to the figure.

Die erfindungsgemäße Vorrichtung besteht aus den beiden Bunkern 1 und 10, wobei der Bunker 1 als Kühlkammer und der Bunker 10 als Vorkammer dient.The device according to the invention consists of the two bunkers 1 and 10, the bunker 1 serving as a cooling chamber and the bunker 10 as a prechamber.

Der Bunker 10 ist deshalb über dem Bunker 1 angeordnet. Der Bunker 1 besteht aus dem äußeren Mantel und der Innenauskleidung 3. Beim äußeren Mantel 2 kann es sich beispielsweise um eine Stahlkonstruktion handeln, während die Innenauskleidung 3 aus einem den jeweiligen Temperaturbedingungen angepaßten feuerfesten keramischen Material besteht. In seinem Oberteil weist der Bunker 1 die Eintrittsöffnung 4 auf, in die die Austrittsöffnung 14 des Bunkers 10 hineinragt. Wie aus der Abbildung ersichtlich ist, weist der Bunker 1 in seinem unteren Teil eine konische Verjüngung auf, an deren unterem Ende sich die Austrittsöffnung 5 für das gekühlte Schüttgut befindet. Selbstverständlich ist diese Austrittsöffung mit einem Verschluß versehen, der hier aber nicht dargestellt worden ist. Es kann sich dabei jedoch um eine Konstruktion handeln, wie sie bei derartigen Vorrichtungen üblich ist. Das gasförmige Kühlmedium wird von unten über den Gasverteiler 6 in das im Bunker 1 befindliche Schüttgut eingeleitet und wird nach Passieren desselben über den Absaugstutzen 7 wieder abgezogen. Die in der Abbildung dargestellte Ausführungsform des Gasverteilers 6 stellt selbstverständlich nur eine mögliche Variante dessen dar, wie das gasförmige Kühlmedium in das Schüttgut eingeleitet werden kann. Selbstverständlich ist hier auch eine andere Ausführungsform der Gaseinleitung möglich, beispielsweise in der Form, daß das gasförmige Kühlmedium von vornherein in zwei Teilströme aufgeteilt wird, die in unterschiedlicher Höhe in den Bunker 1 eingeleitet werden. Wie aus der Abbildung zu ersehen ist, weist die Innenauskleidung 3 in den einzelnen Bereichen das Bunkers 1 eine unterschiedliche Schichtdicke auf. Sie ist im Bereich der konischen Verjüngung oberhalb der Austrittsöffnung 5 geringer als im Oberteil des Bunkers 1. Damit wird der unterschiedlichen Wärmebeanspruchung innerhalb der einzelnen Wärmezonen des Bunkers 1 Rechnung getragen.The bunker 10 is therefore arranged above the bunker 1. The bunker 1 consists of the outer casing and the inner lining 3. The outer casing 2 can be a steel structure, for example, while the inner casing 3 consists of a refractory ceramic material which is adapted to the respective temperature conditions. In its upper part, the bunker 1 has the inlet opening 4, into which the outlet opening 14 of the bunker 10 projects. As can be seen from the figure, the bunker 1 has a conical taper in its lower part, at the lower end of which there is the outlet opening 5 for the cooled bulk material. Of course, this outlet opening is provided with a closure, which has not been shown here. However, this can be a construction as is customary in such devices. The gaseous cooling medium is introduced from below via the gas distributor 6 into the bulk material located in the bunker 1 and, after passing through it, is drawn off again via the suction nozzle 7. The embodiment of the gas distributor 6 shown in the figure is of course only one possible variant of how the gaseous cooling medium can be introduced into the bulk material. Of course, another embodiment of the gas inlet is also possible here, for example in the form that the gaseous cooling medium is divided into two partial streams from the outset, which are introduced into the bunker 1 at different heights. As can be seen from the figure, the inner lining 3 has a different layer thickness in the individual areas of the bunker 1. It is lower in the area of the conical taper above the outlet opening 5 than in the upper part of the bunker 1. The different thermal stresses within the individual heat zones of the Bunkers 1 taken into account.

Der über dem Bunker 1 angeordnete Bunker 10, der als Vorkammer dient, weist ebenfalls einen äußeren Mantel 11 und eine Innenauskleidung 12 auf. Es kann sich auch hier beim äußeren Mantel 11 um eine Stahlkonstruktion handeln, während die Innenauskleidung 12 wiederum aus feuerfestem keramischen Material besteht. Der Bunker 10 verjüngt sich in seinem Unterteil zur Austrittsöffnung 14 hin, die so dimensioniert ist, daß sie in der Eintrittsöffnung 4 des Bunkers 1 ausreichend Spiel hat. Beide Bunker sind dabei durch den Kompensator 15 miteinander verbunden. Dieser sorgt für einen gasdichten Abschluß, während gleichzeitig das Wärmedehnverhalten beider Bunker nicht beeinträchtigt wird. Das zu kühlende Schüttgut, wie z. B. der heiße Koks, gelangt über die Einfüllöffnung 13 in den Bunker 10 und nach Passieren desselben in den Bunker 1. Die strichpunktierten Linien zeigen dabei die Aufböschung des Schüttgutes in den beiden Bunkern. Selbstverständlich ist die Einfüllöffnung 13 mit einem in der Abbildung nicht dargestellten Deckel bzw. einer Einfüllschleuse versehen. Hierbei kann wiederum auf bekannte und bereits bewährte Konstruktionen zurückgegriffen werden. Im Oberteil des Bunkers 10 befindet sich der Absaugstutzen 18, durch den entweichendes Gas aus der Vorkammer abgezogen werden kann.The bunker 10 arranged above the bunker 1, which serves as a prechamber, also has an outer jacket 11 and an inner lining 12. The outer jacket 11 can also be a steel construction, while the inner lining 12 is made of refractory ceramic material. The bunker 10 tapers in its lower part towards the outlet opening 14, which is dimensioned such that it has sufficient play in the inlet opening 4 of the bunker 1. Both bunkers are connected to each other by the compensator 15. This ensures a gas-tight seal, while at the same time the thermal expansion behavior of both bunkers is not impaired. The bulk material to be cooled, such as. B. the hot coke, passes through the filling opening 13 into the bunker 10 and after passing through the same in the bunker 1. The dash-dotted lines show the embankment of the bulk material in the two bunkers. Of course, the filling opening 13 is provided with a lid or a filling lock, not shown in the figure. Here, in turn, known and already proven designs can be used. In the upper part of the bunker 10 there is the suction nozzle 18 through which escaping gas can be withdrawn from the prechamber.

Beim vorliegenden Ausführungsbeispiel werden die Bunker 1 und 10 von der Gerüstkonstruktion 9 gehalten, die als Stahl- oder Betonbau ausgeführt werden kann. Der Bunker 1 ist dabei mittels der Auflagefläche 8 an der Gerüstkonstruktion 9 befestigt, während der Bunker 10 an seiner Außenseite die Aufnahmepratzen 16 aufweist, die auf den Endflächen 17 der Gerüstkonstruktion 9 aufliegen. Auf diese Art und Weise haben beide Bunker ausreichend Halt, während ihr Wärmedehnverhalten nicht beeinträchtigt wird.In the present exemplary embodiment, the bunkers 1 and 10 are held by the scaffold structure 9, which can be constructed as a steel or concrete structure. The bunker 1 is fastened to the scaffold structure 9 by means of the support surface 8, while the bunker 10 has on its outside the receiving claws 16 which rest on the end faces 17 of the scaffold structure 9. In this way, both bunkers have sufficient hold while their thermal expansion behavior is not impaired.

Abschließend soll nochmals darauf hingewiesen werden, daß die im Ausführungsbeispiel dargestellte äußere Form der Bunker mit zylindrischem Oberteil und konischer Verjüngung im Unterteil für die erfindungsgemäße Vorrichtung keineswegs zwingend vorgeschrieben ist. Es kann vielmehr auch eine andere Formgebung der Bunker gewählt werden. Ebenso wird man deren Dimensionierung natürlich den jeweiligen Erfordernissen der Praxis anpassen.Finally, it should be pointed out once again that the outer shape of the bunkers with cylindrical upper part and conical tapering in the lower part shown in the exemplary embodiment is by no means mandatory for the device according to the invention. Rather, a different shape of the bunker can be chosen. Likewise, their dimensions will of course be adapted to the respective practical requirements.
