Beschreibungdescription
Die Erfindung betrifft eine Konverteranlage mit zwischen dem Hut eines kippbarenThe invention relates to a converter system with between the hat of a tiltable
Konverters und der Mündung eines Rauchgaskamins vorgesehenen Dichtring, wobei Antriebe vorgesehen sind, mit denen der Dichtring so weit vom Konverterhut wegfahrbar ist, daß der Konverter ungehindert gekippt werden kann.Converter and the mouth of a flue gas chimney provided sealing ring, drives are provided with which the sealing ring can be moved so far away from the converter hat that the converter can be tilted freely.
Konverter zur Stahlerzeugung sind im Regelfall mit einem wassergekühltenConverters for steel production are usually with a water-cooled
Kühlkamin ausgerüstet, um die an der Mündung austretenden Prozeßgase zu erfassen und abzuleiten. Die Konvertermündung ist dabei von der Eintrittsöffnung des Kühlkamins beabstandet, um das Gefäß zum Chargieren und zum Entleeren unter der Kaminöffnung vorbei bewegen zu können.Cooling chimney equipped to record and discharge the process gases emerging at the mouth. The converter mouth is spaced from the inlet opening of the cooling chimney in order to be able to move the vessel past under the chimney opening for charging and emptying.
Bei Anlagen, die mit unterdrückter Verbrennung der Prozeßgase arbeiten, ist während des Prozesses der Spalt möglichst vollständig geschlossen zu halten. Dadurch soll der Zutritt von Luft zum abgesaugten Konvertergas begrenzt werden, um das brennbare Gas mit seinem hohen Heizwert unverbrannt zu erfassen und nach entsprechender Kühlung und Reinigung der weiteren Verwertung zuzuführen. Zu diesem Zweck wird üblicherweise ein beweglicher wassergekühlter Ring am Kamineintritt angeordnet, der mittels hydraulischer oder anderer mechanischer Vorrichtung abgesenkt werden kann, um so den Luftspalt während des Prozesses zu verringern.In systems that work with suppressed combustion of the process gases, the gap must be kept as completely closed as possible during the process. This is intended to limit the access of air to the extracted converter gas in order to record the combustible gas with its high calorific value unburned and, after appropriate cooling and cleaning, to pass it on for further use. For this purpose, a movable water-cooled ring is usually arranged at the chimney inlet, which can be lowered by means of hydraulic or other mechanical devices, so as to reduce the air gap during the process.
Da der Ring aufgrund seiner notwendigen Beweglichkeit einen baulich bedingten Abstand zum feststehenden Kamin Eintritt hat, bleibt ein Luftspalt zwischen den beiden Bauteilen bestehen. An diesem Spalt kann jedoch weiterhin sowohl Luft in das Prozessgas eintreten oder aber heißes staubhaltiges Prozeßgas in die Arbeitsräume austreten. Beides ist aber unerwünscht und soll gerade verhindert werden. Weiterhin sind verschiedene zusätzliche Vorrichtungen zur Abdichtung des Restspaltes zwischen dem Ring und der Kühlhaube bekannt, so z.B. eine Wassertasse, die Abschleierung mit Dampf oder Inertgas, oder Umkehrungen mittels Schürze, die eine Art Labyrinth-Abdichtung herstellen soll.Since the ring has a structural distance from the fixed chimney due to its necessary mobility, an air gap remains between the two components. At this gap, however, air can still enter the process gas or hot dusty process gas can escape into the work rooms. Both are undesirable and should be prevented. Furthermore, various additional devices for sealing the remaining gap between the ring and the cooling hood are known, for example a water cup, the covering with steam or inert gas, or reversals using an apron, which is intended to produce a type of labyrinth seal.
Diese bekannten Dichtungssysteme weisen Nachteile auf, die von den extremen Betriebsbedingungen am Einbauort und der schlechten Zugänglichkeit hervorgerufen werden. So benötigt eine Wassertasse viel Platz, darüber hinaus ist sie störanfällig und wartungsaufwendig.These known sealing systems have disadvantages which are caused by the extreme operating conditions at the installation site and the poor accessibility. A water cup needs a lot of space, moreover, it is prone to failure and requires a lot of maintenance.
Für eine Abschleierung werden teuere Betriebsstoffe verbraucht.Expensive consumables are consumed for a veil.
Labyrinthähnliche Schürzen sind wegen der erforderlichen Kühlung aufwendig, sie sind von begrenzter Wirkung durch die Restspalten und darüber hinaus schlecht zugänglich.Labyrinth-like aprons are expensive because of the required cooling, they have a limited effect due to the remaining gaps and are also difficult to access.
Weitere Nachteile sind bei allen genannten Dichtungssysteme die Wartung und Reinigung der Teile durch Schlacken und Stahlanbackungen im Dichtungsbereich, insbesondere wegen der schlechten Zugänglichkeit.Further disadvantages are the maintenance and cleaning of the parts by slag and steel caking in the sealing area in all of the sealing systems mentioned, in particular because of the poor accessibility.
Aus JP 63-42321 ist ein Rauchgaskamin bekannt, bei dem der Mündungsbereich koaxial zu einem zentralen Kaminrohr beweglich angeordnet ist. Diese Mündung iegt sich lose auf den Konverter auf.A flue gas chimney is known from JP 63-42321, in which the mouth region is arranged to be movable coaxially with a central chimney pipe. This mouth is loosely attached to the converter.
Die Erfindung hat sich, in Kenntnis der o.g. Schwierigkeiten, zum Ziel gesetzt, mit konstruktiv einfachen Mitteln den spaltischen Konverter und Kamin während des Betriebes dicht zu schließen und darüber hinaus die Möglichkeit zu schaffen, eine gasdichte Verbindung zwischen Kamin und Konverter herzustellen und so die Anlage auch unter Überdruck zu betreiben.The invention has, with knowledge of the above. Difficulties, with the goal of using structurally simple means to close the gap converter and chimney tightly during operation and also to create the possibility of establishing a gas-tight connection between chimney and converter and thus operating the system even under excess pressure.
Die Erfindung erreicht dieses Ziel durch die kennzeichnenden Merkmale des Anspruchs 1. Die übrigen Ansprüche sind vorteilhafte Weiterbildungen der Erfindung.The invention achieves this aim by the characterizing features of claim 1. The remaining claims are advantageous developments of the invention.
Erfindungsgemäß wird der Dichtring als Hülse ausgebildet, die den Rauchgaskamin von außen umfasst. Hierbei ist die Mündung der Hülse in Schließstellung am Konverterhut anlehnbar. Die Hülse weist dabei vertikale Trennschnitte auf, wobei ein Schließring entsteht, der aus zwei oder mehreren zueinander beweglichen Teilsegmenten zusammengesetzt ist. Die einzelnen Segmente weisen einen Innenradius auf, der mit dem äußeren Radius des Kaminunterteils übereinstimmt. Sobald die Teilsegmente des Schließringes an der Kaminwandung anliegen, ist derAccording to the invention, the sealing ring is designed as a sleeve which surrounds the flue gas fireplace from the outside. Here, the mouth of the sleeve is in the closed position on Converter hat can be leaned on. The sleeve has vertical separating cuts, whereby a locking ring is formed, which is composed of two or more sub-segments that are movable relative to one another. The individual segments have an inner radius that corresponds to the outer radius of the lower part of the chimney. As soon as the sub-segments of the locking ring lie against the chimney wall, the
Ring dicht geschlossen.Ring tightly closed.
Außen an den Segmenten des Schließringes sind Vorrichtungen angebracht, mit denen diese horizontal auseinandergeschoben werden können. Dadurch lösen sich die Ringe in der Mitte von der Kühlkaminwand ab und können nun beliebig auf dieDevices are attached to the outside of the segments of the locking ring with which they can be pushed apart horizontally. As a result, the rings in the middle detach from the chimney wall and can now be placed on the
Konvertermündung abgesenkt bzw. von ihr wegbewegt werden.Converter mouth lowered or moved away from it.
Sobald der vertikale Bewegungsvorgang beendet ist und der Ring in der erreichten Stellung verbleiben soll, werden die Ringsegmente von der Vorrichtung wieder zusammengezogen bis sie erneut dicht an der Wand des Kamins anliegen. Soll der Schließring in eine neue Position gebracht werden, so werden zunächst die Segmente wieder mit Hilfe der Vorrichtung voneinander gelöst, der Ring wird von der Hubvorrichtung in die neue Stellung gebracht und wieder geschlossen.As soon as the vertical movement process has ended and the ring is to remain in the position reached, the ring segments are pulled together again by the device until they are again close to the wall of the fireplace. If the locking ring is to be brought into a new position, the segments are first detached from one another again with the aid of the device, the ring is brought into the new position and closed again by the lifting device.
Der horizontale Abstand der einzelnen Segmente läßt sich in einem vorbestimmtenThe horizontal distance between the individual segments can be predetermined
Bereich einstellen. Dadurch wird es möglich, den Ring so auszubilden, daß er über den Rand des Konverters abgesenkt werden kann und beim Schließen diesen ebenfalls dicht umfaßt. Damit kann weder Luft in das Konvertergas eingesaugt werden, noch dieses aus dem System in den Arbeitsraum entweichen.Set range. This makes it possible to design the ring so that it can be lowered over the edge of the converter and also encloses it tightly when closed. This means that air cannot be sucked into the converter gas, nor can it escape from the system into the work area.
Darüber hinaus können aber auch beliebige Zwischenstellungen angefahren werden, wobei stets sichergestellt ist, daß der Spalt zwischen dem Kamin und dem Schließring völlig abgedichtet ist.In addition, any intermediate positions can also be approached, always ensuring that the gap between the chimney and the locking ring is completely sealed.
Die Ringsegmente können auch so befestigt werden, daß sie an ihrem oberen Rand schwenkbar an einer Haltevorrichtung angebracht sind und seitlich nach oben schalenförmig in eine geöffnete Stellung oder nach unten in die geschlossene Stellung bewegt werden. Für die Schwenkbewegungen können entweder geeignete Hebegestänge fest angeordnet oder aber bewegliche Hydraulikzylinder angebracht werden. Die Ringsegmente sind aus wassergekühlten Rohren hergestellt, die dicht miteinander verschweißt sind. Dabei können die Rohre entweder horizontal oder vertikal angeordnet sein. Das Kühlwasser wird durch bewegliche Verbindungsrohre geleitet, welche an die Verteiler der Rohrsegmente angeschlossen sind.The ring segments can also be fastened in such a way that they are pivotally attached to a holding device at their upper edge and are moved laterally in the manner of a bowl into an open position or downwards into the closed position. For the swiveling movements either suitable lifting rods can be fixed or movable hydraulic cylinders can be attached. The ring segments are made from water-cooled pipes that are welded tightly together. The tubes can be arranged either horizontally or vertically. The cooling water is led through movable connecting pipes, which are connected to the distributors of the pipe segments.
Die seitliche Verschiebervorrichtung wird mittels Hydraulikzylindern betätigt oder auch durch mechanische Vorrichtungen wie Schubantrieb oder Hebegestänge. Die erforderliche Energieversorgung erfolgt durch entsprechende flexible Zuleitungen. Die Vorrichtungen sind so konstuiert und eingebaut, daß sie vor Hitze und Schlacke ausreichend geschützt sind.The side shifting device is actuated by means of hydraulic cylinders or also by mechanical devices such as thrust drive or lifting linkage. The necessary energy supply is provided by corresponding flexible supply lines. The devices are designed and installed in such a way that they are adequately protected against heat and slag.
Die Ringsegmente können über eine Führung verbunden sein, die für einen kontrollierten synchronen Bewegungsablauf sorgen. So können beispielsweise Führungsschienen mit Rolienführung am Kaminunterteil und am Schließring dafür sorgen, daß die Bauteile bei den Bewegungen ihre Position zueinander beibehalten.The ring segments can be connected via a guide, which ensure a controlled synchronous movement. For example, guide rails with roller guides on the lower part of the chimney and on the locking ring can ensure that the components maintain their position relative to one another during the movements.
