Definitions
- the invention relates to a coke oven door with at least 2 interlocks, the door body of which is continuously flexible and provided with a pressed-on membrane seal, the door being exposed to a temperature gradient of more than 100 K / m.
- the door contour caused by the temperature load normally deviates greatly from the chamber frame contour, so that a gap of different width is formed over the door height between the door and chamber frame contour, the width of which changes over time.
- the door body designs known today experience considerable thermal deformations due to the thermal loads, which can be approximately 25 mm for doors up to 8 m high.
- the door bodies made of a heavy U-profile with large web heights SH of more than 250 mm the door can only be deformed to an extremely small extent using the bolt forces that are common today.
- the primarily used spring-loaded sealing membranes should therefore cover these relatively large gap widths mainly in the head, middle and foot area of the doors.
- they In order to maintain the required elasticity for bending, they are usually made in thin sheets of at most 1.5 mm. However, these sheet thicknesses are not up to the rough coking plant operation and attack of the mechanical cleaning tools. Considerable maintenance is therefore required.
- the AF diaphragm compression springs must have a characteristic curve which, given the relatively long spring travel, provides enough force to compensate for the diaphragm reaction forces due to the diaphragm bending and, in addition, to ensure a sufficiently high contact pressure (specific sealing strip force q) between the sealing blade and chamber frame in every operating state . If possible, the contact pressure should not fall below a certain minimum value over the entire cooking time. With the previous door designs, this requirement could not be met in most cases.
- DE-PS 25 36 291 proposes that above and below the locking devices (door latch TR) in the metallic door body Resistance-reducing and thus allowing its deflection in the head and foot sections are provided in the door body.
- this measure did not fully meet the expectations placed on high stoves.
- the invention is therefore based on the object of designing a coke oven door in such a way that the aforementioned disadvantages are eliminated.
- the ratio of the door body rigidity (E. I) to the specific sealing strip force (q) is dimensioned so low that the thermal deformation of the door body (T) is largely compensated for by the locking forces (R) and the sealing strip force (q) .
- the chamber frame KR on which the door rests, remains straight.
- the chamber frame wants to thermally deform due to the temperature gradient TGR that is established in the chamber frame. He can be prevented by the anchoring system by the anchoring loads forcibly holding down the chamber frame on the straight (flat) masonry.
- a substantial deformation Yq can only be achieved with a specific sealing strip force q that is generally specified in terms of process technology, however, if the bending stiffness E-1 of the door body is so low that the condition according to the above-mentioned formula is met.
- the following table contains results of the formula for doors between 6 m and 10 m total length. For the determination of these values, it was assumed that f cannot be less than 1 m for procedural reasons and that B is currently usually 500 mm.
- a comparison with the door according to the invention with a total length of 7.5 m according to the table shows, for example, that the proposed door differs to a great extent in its flexural rigidity from conventional ones.
- the gap resulting from the superimposition is significantly smaller than is the case with conventional door constructions with a rigid door body and membrane seal. It has been shown that the gap width that is set can be kept ⁇ 5 mm. Differences of ⁇ 5 mm would only have to be compensated for via the membrane.
- material thicknesses of over 1.5 mm can therefore be used for the membrane seals, which offer sufficient resistance to the use of mechanical cleaning tools and are also suitable for the use of hydraulic high-pressure cleaning.
- the deformed door body is mainly adapted to the chamber frame by the locking and sealing strip forces, the locking forces mentioned are also available as sealing strip forces, and it is avoided that some of the locking forces are ineffective in the frame via stop pieces (Stopper ST) be directed.
- Another advantage of the invention is seen in the fact that deformations of the chamber frame that cannot be completely avoided can be easily compensated for by the proposed door construction over longer periods of time, i.e. the gap width occurring, even in this case ⁇ 5 mm, can be kept. This eliminates the usual adjustment and adjustment work on the pressure elements of the membranes and on the membrane itself.

Abstract
Description
Die Erfindung betrifft eine Koksofentür mit mindestens 2 Verriegelungen, deren Türkörper durchgehend biegeelastisch ausgeführt und mit einer angedrückten Membrandichtung versehen ist, wobei die Tür mit einem Temperaturgradienten von mehr als 100 K/m beaufschlagt ist.The invention relates to a coke oven door with at least 2 interlocks, the door body of which is continuously flexible and provided with a pressed-on membrane seal, the door being exposed to a temperature gradient of more than 100 K / m.
Beim Bau von modernen Koksofenanlagen geht die Entwicklung, wie die Vergangenheit gezeigt hat, zu immer grösseren Koksofenkammern, wobei besonders starke Zunahmen bei der Höhe der Kammern zu beobachten sind. Während früher vornehmlich Öfen mit Kammerhöhen bis zu ca. 4 m und Kammerbreiten bis zu ca. 450 mm gebaut wurden, sind heute Koksofenbatterien mit Kammerhöhen bis zu 8 m und Kammerbreiten bis zu 600 mm erfolgreich in Betrieb bzw. im Bau. Diese Entwicklung hat massgeblich zur Verbesserung der Wirtschaftlichkeit der Kokserzeugung beigetragen.In the construction of modern coke oven plants, as the past has shown, the trend is towards ever larger coke oven chambers, with particularly strong increases in the height of the chambers being observed. While in the past mainly ovens with chamber heights up to approx. 4 m and chamber widths up to approx. 450 mm were built, today coke oven batteries with chamber heights up to 8 m and chamber widths up to 600 mm are successfully in operation or under construction. This development has made a significant contribution to improving the profitability of coke production.
Bei den vorgenannten Abmessungen kommt einer guten Abdichtung der Kammern durch die Koksofentüren aus Umweltschutzgründen eine besondere Bedeutung zu. Dabei wird die Koksofentür durch Riegel, in der Regel 2, manchmal auch 3, gegen den Kammerrahmen gedrückt.With the aforementioned dimensions, a good sealing of the chambers by the coke oven doors is of particular importance for environmental reasons. The coke oven door is pressed against the chamber frame by bolts, usually 2, sometimes 3.
Eine Vielzahl von Türkonstruktionen ist im Laufe der Jahre entwickelt und mit unterschiedlichem Erfolg eingesezt worden. Allgemein ist festzustellen, dass Konstruktion und Bau möglichst über den gesamten Garungsvorgang dicht abschliessender Türen sich mit grösser werdenden Kammeröffnungen immer schwieriger gestalten.A large number of door constructions have been developed over the years and have been used with varying degrees of success. In general, it should be noted that the design and construction of doors that close tightly over the entire cooking process, if possible, are becoming increasingly difficult with increasing chamber openings.
Es ist bekannt, Metall auf Metall dichtende Koksofentüren mit den unterschiedlichsten Formen von Dichtleisten, wie Winkelmembranen, Z-Membranen, Flacheisenmembranen, Keildichtleisten oder dergleichen auszustatten. Alle diese bekannten Dichtungsausführungen, wie sie beispielsweise in Fig. 1 und 2 (Ausschnitt A nach Fig. 1) dargestellt sind, müssen, auch wenn sie über einen gewissen Bereich elastisch sind und durch Druckelemente AF, beispielsweise Federn, zur Anlage gebracht werden, von Zeit zu Zeit entsprechend den durch Temperaturdifferenzen hervorgerufenen Verwerfungen von Kammerrahmen KR und/oder Türkörper T verstellt werden. Dies geschieht bei Flach- bzw. Keilmembranen üblicherweise durch Hammerschläge, bei den elastischen Membranen M durch Nachstellen an Befestigungselementen.It is known to provide metal on metal sealing coke oven doors with the most varied of shapes of sealing strips, such as angle membranes, Z-membranes, flat iron membranes, wedge sealing strips or the like. All of these known seal designs, as shown for example in FIGS. 1 and 2 (section A according to FIG. 1), must, even if they are elastic over a certain range and brought into contact with pressure elements AF, for example springs From time to time according to the distortions of the chamber frame KR and / or door body T caused by temperature differences. In the case of flat or wedge membranes, this is usually done by hammer blows, in the case of the elastic membranes M by adjusting on fastening elements.
Es hat sich nun in der Praxis gezeigt, dass die vorgenannten Massnahmen zum Abdichten der Türen vor allem bei grossen Kammerhöhen nicht immer ausreichend wirksam sind, so dass es zu Belastungen der Umwelt kommt.It has now been shown in practice that the above-mentioned measures for sealing the doors, especially with large chamber heights, are not always sufficiently effective, so that there is a burden on the environment.
Zwischen dem Füllen einer Kammer mit kalter Kohle und dem Garungsende ergeben sich je nach Auslegung der Öfen Zeiträume von 16-25 Stunden. Während dieser Zeit treten unterschiedliche Temperaturbelastungen von Kammerrahmen und Türkörper auf. Diese Temperaturbelastungen bewirken ihrerseits unterschiedliche Temperaturgradienten in Kammerrahmen TGR und Türkörper TGT, die wiederum zu unterschiedlichen Verformungen über die Garungszeit führen. Der Verformungszustand von Kammerrahmen und Türkörper wird weiterhin von Umwelteinflüssen, wie starkem Regen und grossen Temperaturschwankungen, beeinflusst. Vielfach ist auch eine Veränderung der Kammerrahmenform über längere Zeiträume durch Flammenschlag zu beobachten.Depending on the design of the ovens, there are periods of 16-25 hours between filling a chamber with cold coal and the end of cooking. During this time, the chamber frame and door body are exposed to different temperatures. These temperature loads in turn cause different temperature gradients in the chamber frame TGR and door body TGT, which in turn lead to different deformations over the cooking time. The state of deformation of the chamber frame and door body is still influenced by environmental factors such as heavy rain and large temperature fluctuations. In many cases, a change in the shape of the chamber frame can be observed over longer periods due to the flame.
Die infolge der Temperaturbelastung hervorgerufene Türkontur weicht von der Kammerrahmenkontur normalerweise stark ab, so dass sich über die Türhöhe zwischen Tür- und Kammerrahmenkontur ein unterschiedlich breiter Spalt ausbildet, dessen Breite sich über die Zeit verändert.The door contour caused by the temperature load normally deviates greatly from the chamber frame contour, so that a gap of different width is formed over the door height between the door and chamber frame contour, the width of which changes over time.
Der Betrag der thermischen Verformung von Kammerrahmen und Türkörper nimmt mit der Kammerhöhe quadratisch zu, womit der Spalt zwischen Kammerrahmen und Türkörper in gleichem Umfang breiter wird. Es ist daher verständlich, dass die Dichtungsprobleme mit grösser werdender Kammerhöhe wesentlich zunehmen.The amount of thermal deformation of the chamber frame and door body increases quadratically with the chamber height, which widens the gap between the chamber frame and door body to the same extent. It is therefore understandable that the sealing problems increase significantly with increasing chamber height.
Die heute bekannten Türkörperausführungen erfahren infolge der thermischen Belastungen erhebliche thermische Verformungen, die bei Türen bis zu 8 m Höhe ca. 25 mm betragen können. Bei den üblicherweise eingesetzten Türkörpern aus einem schweren U-Profil mit grossen Steghöhen SH von mehr als 250 mm ist eine Rückverformung der Tür mit den heute gebräuchlichen Riegelkräften nur in einem äusserst geringen Umfang möglich.The door body designs known today experience considerable thermal deformations due to the thermal loads, which can be approximately 25 mm for doors up to 8 m high. With the commonly used door bodies made of a heavy U-profile with large web heights SH of more than 250 mm, the door can only be deformed to an extremely small extent using the bolt forces that are common today.
Die eingesetzten, vornehmlich federbelasteten Dichtmembranen sollen daher in der Hauptsache im Kopf-, Mittel- und Fussbereich der Türen diese relativ grossen Spaltbreiten überdecken. Um die dafür erforderliche Biegeelastizität zu erhalten, werden sie üblicherweise in geringen Blechstärken von höchstens 1,5 mm ausgeführt. Diese Blechstärken sind jedoch dem rauhen Kokereibetrieb und Angriff der mechanischen Reinigungswerkzeuge nur unzureichend gewachsen. Ein erheblicher Wartungsaufwand ist daher erforderlich.The primarily used spring-loaded sealing membranes should therefore cover these relatively large gap widths mainly in the head, middle and foot area of the doors. In order to maintain the required elasticity for bending, they are usually made in thin sheets of at most 1.5 mm. However, these sheet thicknesses are not up to the rough coking plant operation and attack of the mechanical cleaning tools. Considerable maintenance is therefore required.
Die Membrandruckfedern AF müssen eine Kennlinie aufweisen, die bei den relativ langen Federwegen genügend Kraft zur Verfügung stellen, um die Membranreaktionskräfte infolge der Membranverbiegung zu kompensieren und darüber hinaus noch einen genügend hohen Anpressdruck (spezifische Dichtleistenkraft q) zwischen Dichtschneide und Kammerrahmen in jedem Betriebszustand zu gewährleisten. Der Anpressdruck sollte nach Möglichkeit über die gesamte Garungszeit einen bestimmten Mindestwert nicht unterschreiten. Mit den bisherigen Türkonstruktionen war diese Forderung meist nicht zu erfüllen.The AF diaphragm compression springs must have a characteristic curve which, given the relatively long spring travel, provides enough force to compensate for the diaphragm reaction forces due to the diaphragm bending and, in addition, to ensure a sufficiently high contact pressure (specific sealing strip force q) between the sealing blade and chamber frame in every operating state . If possible, the contact pressure should not fall below a certain minimum value over the entire cooking time. With the previous door designs, this requirement could not be met in most cases.
Um diese vorstehend geschilderten Schwierigkeiten zu verringern, ist auch schon vorgeschlagen worden, Türen mit biege-elastischen Türkörpern T auszustatten. So wird mit der DE-PS 25 36 291 unter anderem vorgeschlagen, dass oberhalb und unterhalb der Verriegelungsvorrichtungen (Türriegel TR) im metallischen Türkörper widerstandsverringernde und damit dessen Durchbiegung in den Kopf- und Fusspartien ermöglichende Aussparungen im Türkörper vorgesehen werden. Diese Massnahm hat jedoch bei hohen Öfen nicht die in sie gestellten Erwartungen voll erfüllt.In order to reduce these difficulties described above, it has also been proposed to equip doors with bend-elastic door bodies T. For example, DE-PS 25 36 291 proposes that above and below the locking devices (door latch TR) in the metallic door body Resistance-reducing and thus allowing its deflection in the head and foot sections are provided in the door body. However, this measure did not fully meet the expectations placed on high stoves.
Der Erfindung liegt daher die Aufgabe zu Grunde, eine Koksofentür so auszubilden, dass die vorgenannten Nachteile beseitigt werden. Hierzu wird erfindungsgemäss vorgeschlagen, dass das Verhältnis von Türkörpersteifigkeit (E. I) zur spezifischen Dichtleistenkraft (q) so gering bemessen ist, dass die thermische Verformung des Türkörpers (T) überwiegend durch die Verriegelungskräfte (R) und die Dichtleistenkraft (q) kompensiert wird.The invention is therefore based on the object of designing a coke oven door in such a way that the aforementioned disadvantages are eliminated. For this purpose, it is proposed according to the invention that the ratio of the door body rigidity (E. I) to the specific sealing strip force (q) is dimensioned so low that the thermal deformation of the door body (T) is largely compensated for by the locking forces (R) and the sealing strip force (q) .
Diese Bedingungen sind, wie gefunden wurde, dann gegeben, wenn die Koksofentür der Formel:
Die Wirkungsweise der erfindungsgemässen Tür wird im folgenden an Hand der Zeichnungen, die als ein Ausführungsbeispiel eine Tür mit 2 Riegeln darstellen, näher erläutert.The mode of operation of the door according to the invention is explained in more detail below with reference to the drawings, which represent a door with 2 bolts as an exemplary embodiment.
Es zeigen:
- Fig. 3 die Verformung der Tür durch die Temperaturlast;
- Fig. 4 die Verformung der Tür durch Riegel- und Dichtleistenkraft;
- Fig. 5 die Verformung der Tür durch Temperaturlast und Riegel- sowie Dichtleistenkraft und
- Fig. 6 eine Ansicht der Tür, in der die wesentlichen Abmessungen eingetragen sind.
- Figure 3 shows the deformation of the door by the temperature load.
- Figure 4 shows the deformation of the door by locking and sealing strip force.
- Fig. 5, the deformation of the door by temperature load and bolt and sealing strip force and
- Fig. 6 is a view of the door in which the essential dimensions are entered.
Für die vereinfachte Darstellung der sich einstellenden Verformungen wird angenommen, dass der Kammerrahmen KR, auf dem die Tür aufliegt, gerade (plan) bleibt. In Wirklichkeit will sich jedoch der Kammerrahmen thermisch verformen auf Grund des sich einstellenden Temperaturgradienten TGR im Kammerrahmen. Durch das Verankerungssystem kann er daran gehindert werden, indem die Verankerungslasten den Kammerrahmen auf dem geraden (planen) Mauerwerk mit Gewalt niederhalten.For a simplified representation of the deformations that occur, it is assumed that the chamber frame KR, on which the door rests, remains straight. In reality, however, the chamber frame wants to thermally deform due to the temperature gradient TGR that is established in the chamber frame. He can be prevented by the anchoring system by the anchoring loads forcibly holding down the chamber frame on the straight (flat) masonry.
Im Betriebszustand (Fig. 3) erfährt die auf dem Kammerrahmen aufliegende Tür eine thermische Verformung auf Grund des sich im Türkörper einstellenden Temperaturgradienten TGT sowie des thermischen Ausdehnungskoeffizienten des Türwerkstoffes von 0,9-2 10-5 K-'. Die Türdurchbiegung in Türmitte ist in Fig. 3 durch Yth dargestellt.In the operating state (FIG. 3), the door resting on the chamber frame undergoes thermal deformation due to the temperature gradient TGT which arises in the door body and the thermal expansion coefficient of the door material of 0.9-2 10-5 K- '. The door deflection in the middle of the door is shown in Fig. 3 by Y th .
Gleichzeitig erfährt die Tür eine Verformung etwa gemäss Fig. 4 auf Grund der Verriegelungskräfte R und der spezifischen Dichtleistenkräfte q, die üblicherweise zwischen 10 und 30 kp/cm liegen. Die Türverformung in Türmitte ist mit Yq bezeichnet. In der Praxis treten beide Belastungsfälle gleichzeitig auf, d.h. es tritt eine Überlagerung der Verformungen gemäss Fig. 5 ein, Yth-Yq=Y.At the same time, the door undergoes deformation as shown in FIG. 4 due to the locking forces R and the specific sealing strip forces q, which are usually between 10 and 30 kp / cm. The door deformation in the middle of the door is labeled Yq. In practice, both load cases occur simultaneously, ie the deformations according to FIG. 5 are superimposed, Y th -Yq = Y.
Eine wesentliche Verformung Yq ist bei im allgemeinen verfahrenstechnisch vorgegebener spezifischer Dichtleistenkraft q jedoch nur erreichbar, wenn die Biegesteifigkeit E-1 des Türkörpers so gering ist, dass die Bedingung nach der oben erwähnten Formel erfüllt wird.A substantial deformation Yq can only be achieved with a specific sealing strip force q that is generally specified in terms of process technology, however, if the bending stiffness E-1 of the door body is so low that the condition according to the above-mentioned formula is met.
Die vorstehenden Ausführungen bezogen sich, wie erwähnt, auf eine Koksofentür mit 2 Riegeln und einem planen Kammerrahmen. In der Praxis ist es jedoch meistens nicht auszuschliessen, dass auch der Kammerrahmen eine thermische Verformung erfährt. In diesem Fall kann es sich als zweckmässig erweisen, eine dritte Verriegelung in der Mitte der Tür anzuordnen.As mentioned, the above explanations relate to a coke oven door with 2 bolts and a flat chamber frame. In practice, however, it can usually not be ruled out that the chamber frame will also experience thermal deformation. In this case, it can be useful to place a third lock in the middle of the door.
Beispielsweise Ergebnisse der Formel für Türen zwischen 6 m und 10 m Gesamtlänge enthält die folgende Tabelle. Für die Ermittlung dieser Werte wurde davon ausgegangen, dass f aus verfahrenstechnischen Gründen nicht kleiner als 1 m sein kann und B heute üblicherweise bei 500 mm liegt.
Herkömmliche Koksofentüren aus Grauguss mit ca. 7,30 m Gesamtlänge weisen für E-1 Werte von q 4,5·1012 bis 5,0·1012 mm 3 auf.Conventional coke oven doors made of gray cast iron with a total length of approx. 7.30 m have values of q 4.5 · 10 12 to 5.0 · 10 12 m m 3 for E -1 .
Der Vergleich mit der erfindungsgemässen Tür mit 7,5 m Gesamtlänge gemäss Tabelle zeigt beispielsweise, dass sich die vorgeschlagene Tür in ihrer Biegesteifigkeit von herkömmlichen in hohem Masse unterscheidet.A comparison with the door according to the invention with a total length of 7.5 m according to the table shows, for example, that the proposed door differs to a great extent in its flexural rigidity from conventional ones.
Durch die Erfindung wird erreicht, dass der sich auf Grund der Überlagerung (gemäss Fig. 5) ergebende Spalt wesentlich geringer ist als es bei üblichen Türkonstruktionen mit starrem Türkörper und Membrandichtung der Fall ist. Es hat sich gezeigt, dass die sich einstellende Spaltbreite < 5 mm gehalten werden kann. Über die Membrane müssten also nur noch Differenzen von ± 5 mm ausgeglichen werden.It is achieved by the invention that the gap resulting from the superimposition (according to FIG. 5) is significantly smaller than is the case with conventional door constructions with a rigid door body and membrane seal. It has been shown that the gap width that is set can be kept <5 mm. Differences of ± 5 mm would only have to be compensated for via the membrane.
Bei der erfindungsgemässen Koksofentür können daher Materialstärken für die Membrandichtungen von-über 1,5 mm verwendet werden, die ausreichende Widerstandskraft gegen den Einsatz mechanischer Reinigungswerkzeuge bieten und auch geeignet sind für die Anwendung einer hydraulischen Hochdruckreinigung.In the coke oven door according to the invention, material thicknesses of over 1.5 mm can therefore be used for the membrane seals, which offer sufficient resistance to the use of mechanical cleaning tools and are also suitable for the use of hydraulic high-pressure cleaning.
Dadurch, dass die Anpassung des verformten Türkörpers an den Kammerrahmen überwiegend durch die Riegel- und Dichtleistenkräfte erfolgt, stehen die genannten Riegelkräfte auch als Dichtleistenkraft zur Verfügung, und es wird vermieden, dass ein Teil der Riegelkräfte über Anschlagstücke (Stopper ST) wirkungslos in den Rahmen geleitet werden.Because the deformed door body is mainly adapted to the chamber frame by the locking and sealing strip forces, the locking forces mentioned are also available as sealing strip forces, and it is avoided that some of the locking forces are ineffective in the frame via stop pieces (Stopper ST) be directed.
Ein weiterer Vorteil der Erfindung wird darin gesehen, dass nicht ganz zu vermeidende Verformungsänderungen des Kammerrahmens über längere Zeiträume von der vorgeschlagenen Türkonstruktion leicht ausgeglichen werden können, d.h. die auftretende Spaltbreite, auch in diesem Fall < 5 mm, gehalten werden kann. Damit entfallen die üblicherweise notwendigen Einstell- und Justierarbeiten an Andruckelementen der Membranen sowie an der Membrane selbst.Another advantage of the invention is seen in the fact that deformations of the chamber frame that cannot be completely avoided can be easily compensated for by the proposed door construction over longer periods of time, i.e. the gap width occurring, even in this case <5 mm, can be kept. This eliminates the usual adjustment and adjustment work on the pressure elements of the membranes and on the membrane itself.
