Abstract
Description
Die Erfindung betrifft ein Verfahren zur Verbesserung der Qualität, insbesondere zur Erhöhung des Gehaltes an flüchtigen Kohlenwasserstoffen des bei der Verkokung von Steinkohne in Horizontalkammerverkokungsöfen gebildeten Gases, wobei das Gas über den zwischen Ofenfüllung und Koksofendecke verbleibenden horizontal verlaufenden und an die Vorlage der Koksofenbatterie angeschlossenen Gassammelraum abgesaugt wird.The invention relates to a method for improving the quality, in particular for increasing the content of volatile hydrocarbons in the gas formed in the coking of hard coal in horizontal chamber coking ovens, the gas being sucked off via the gas collection space which runs horizontally between the oven filling and the coke oven ceiling and is connected to the template of the coke oven battery becomes.
Bei den heute fast ausschliesslich eingesetzten Koksöfen wird die Kokskohle von oben aus in die annähernd rechteckförmigen Koksöfen eingefüllt und dann von den Längsseiten her aufgeheizt und verkokt. Nach dem Einfüllen der Kokskohle wird die Ofenfüllung maschinell planiert, um zwischen Koksofendecke und Ofenfüllung einen gleichmässig ausgebildeten und ausreichend grossvolumigen Gassammelraum zu schaffen, über den das Gas dann über die gesamte Länge des Koksofens abgesaugt wird. Seitlich werden die Öfen durch Koksofentüren mit Türstopfen aus feuerfestem Material begrenzt, wobei über die Türstopfen einerseits ein Schutz für die Koksofentüren selbst und andererseits eine begrenzt gleichförmige Verkokung der Ofenköpfe dadurch erreicht wird, dass die Ofenfüllung über den Türstopfen bis in den Bereich der ersten Heizzüge zurückgedrängt ist. Durch diese Ausbildung des Türstopfens ist die Dichtungsfuge der Wärmeeinwirkung des ersten Heizzuges und des Kokskuchens weitgehend entzogen, wobei zwischen dem Türstopfen und der Ofenwandung ein schmaler von oben nach unten beidseitig des Türstopfens durchgehender Kanal verbleibt. Durch diesen schmalen Kanal kann eine ganz geringe Menge an Gas am Türkörper entlang nach oben entweichen. Aufgrund der Ausbildung dieses schmalen Kanals kommt es insbesondere zu Beginn des Verkokungsprozess zu hohen Drükken, so dass das Gas nicht durch die Kanäle abgeführt, sondern vielmehr durch die Dichtleiste hindurch in die Atmosphäre entweicht. Entsprechend schädliche Immissionen sind die Folge.In the coke ovens used almost exclusively today, the coking coal is filled from above into the approximately rectangular coke ovens and then heated and coked from the long sides. After the coking coal has been filled in, the furnace filling is leveled mechanically in order to create a uniformly designed and sufficiently large-volume gas collecting space between the coke oven ceiling and the furnace filling, through which the gas is then sucked off over the entire length of the coke oven. The ovens are laterally delimited by coke oven doors with door plugs made of refractory material.On the one hand, the door plugs provide protection for the coke oven doors themselves and, on the other hand, limited coking of the furnace heads is achieved by pushing the furnace filling over the door plugs back into the area of the first heating flues is. By this design of the door plug, the sealing joint is largely removed from the heat of the first heating flue and the coke cake, a narrow channel remaining from top to bottom on both sides of the door plug remaining between the door plug and the furnace wall. A very small amount of gas can escape upwards along the door body through this narrow channel. Due to the formation of this narrow channel, high pressures occur in particular at the beginning of the coking process, so that the gas does not escape through the channels, but rather escapes into the atmosphere through the sealing strip. This results in harmful emissions.
Es sind verschiedene Vorschläge bekannt geworden, die Kanäle am Türkörper bzw. am Türstopfen zu erweitern. Diese Versuche zeigten auf der Druckseite kurzfristige Erfolge. Die Kanäle setzen sich jedoch aufgrund des dann erhöhten Temperaturgefälles um so schneller mit Teerkondensaten zu, was sowohl bezüglich der Gasführung wie auch der Reinigung der Koksofentüren erhebliche Probleme mit sich bringt. Ein solcher Vorschlag ist aus Coke and Gas ff, (Juni 1953), Seiten 221 und 222 bekannt. Dort ist eine Koksofentür vorgeschlagen worden, die einen Steinstopfen aufweist, der im Mittelpunkt eine Art Bohrung oder kleinen Kanal aufweist, durch den Gas abgeführt werden kann. Dieses Gas wird allerdings nur in etwa 1 m Höhe über Ofensohle durch einen Querkanal zugeführt und oben im Bereich des horizontalen Gassammelraums wieder herausgeführt. Die Temperatur des zu Beginn des Verkokungsvorganges in diesen Steinkanal einströmenden Gases ist so gering und der Steinstopfen selbst noch so weit abgekühlt, dass es frühzeitig zu Ansätzen und Niederschlag von Kondensat kommt, so dass diese kleinen Öffnungen zuwachsen und dann für den Gasfluss nicht mehr zur Verfügung stehen. Selbst dann, wenn dieser kleine Kanal offengehalten werden könnte, müsste aber die Hauptmenge des entstehenden Gases nach wie vor durch die Ofenfüllung hindurch in den oberen horizontalen Gassammelraum aufsteigen. Der Gehalt an flüssigen Kohlenwasserstoffen könnte damit allenfalls kaum messbar erhöht werden.Various proposals have become known for expanding the channels on the door body or on the door plug. These attempts showed short-term success on the print side. However, due to the then increasing temperature gradient, the channels clog all the more quickly with tar condensates, which poses considerable problems both with regard to the gas flow and the cleaning of the coke oven doors. Such a proposal is known from Coke and Gas ff, (June 1953), pages 221 and 222. There a coke oven door has been proposed which has a stone plug which has a kind of bore or small channel in the center through which gas can be discharged. However, this gas is only fed in through a transverse channel at a height of about 1 m above the furnace bottom and is led out again at the top in the area of the horizontal gas collecting space. The temperature of the gas flowing into this stone channel at the start of the coking process is so low and the stone plug itself has cooled so far that condensate builds up and precipitates early, so that these small openings grow and are then no longer available for the gas flow stand. Even if this small channel could be kept open, the bulk of the resulting gas would still have to rise through the furnace filling into the upper horizontal gas collection space. At best, the content of liquid hydrocarbons could hardly be increased measurably.
Die US-A-4086145 beschreibt eine Koksofentür, wo der aus feuerfestem Material bestehende Steinstopfen durch eine sogenannte Barriere ersetzt ist. Diese Barriere wird von einem oder mehreren Doppel-T-Trägern gebildet, die sich gegenseitig abstützen und deren Flanken durch zusätzliche Einbauten abgestützt werden. Abgesehen davon, dass in der US-A-4086145 an keiner Stelle erwähnt ist, dass mit dieser Tür ein Verfahren zur Verbesserung der Gasqualität durchgeführt werden soll oder kann, ist dies auch deshalb nicht möglich, weil die Freiräume innerhalb der Barriere so bemessen sind, dass dort allenfalls die auch gewünschte Druckentlastung an den Türdichtungen erzielt werden kann. Im übrigen sind auch hier die Temperaturunterschiede so gross, dass die Freiräume durch Kondensat u.a. Verschmutzungen schnell zuwachsen. Nach wie vor müssen daher bei derartig ausgebildeten Koksofentüren die Gase annähernd insgesamt durch die Ofenfüllung hindurch in den oberen horizontalen Gassammelraum aufsteigen. Lediglich während der zeitlich geringen Zeiträume, in denen an der Koksofentür ein überhöhter Druck auftritt, vor allem zu Beginn des Verkokungsprozesses, ist hier eine Druckentlastung zu verzeichnen. Dies hat auf die Gasqualität jedoch keinen Einfluss. Aus diesem Grund kann aus dieser rein konstruktiven Veränderung der Form des Steinstopfens bzw. der Barriere auch keineswegs auf eine bestimmte Verfahrensführung zur Verbesserung der Gasqualität geschlossen werden.US-A-4086145 describes a coke oven door where the stone plug made of refractory material is replaced by a so-called barrier. This barrier is formed by one or more double T-beams, which support each other and whose flanks are supported by additional internals. Apart from the fact that there is no mention in US-A-4086145 that a method for improving the gas quality should or can be carried out with this door, this is also not possible because the free spaces within the barrier are dimensioned in such a way that that at most the desired pressure relief can be achieved on the door seals. Incidentally, the temperature differences are so great here that the free spaces due to condensate, among other things. Soiling quickly. Therefore, in the case of coke oven doors designed in this way, the gases have to rise approximately as a whole through the furnace filling into the upper horizontal gas collecting space. Only during the short time periods in which excessive pressure occurs at the coke oven door, especially at the beginning of the coking process, can pressure relief be noted here. However, this has no influence on the gas quality. For this reason, it cannot be inferred from this purely constructive change in the shape of the stone plug or the barrier that the gas quality is improved.
Der Erfindung liegt die Aufgabe zugrunde, die Gasqualität zu verbessern und dabei gleichzeitig die Ausgarung der Kopfpartien der Ofenfüllung zu verbessern und zu vergleichmässigen.The invention has for its object to improve the gas quality and at the same time to improve and even out the cooking of the top parts of the furnace filling.
Die Aufgabe wird gemäss der Erfindung dadurch gelöst, dass das Gas gleichzeitig auch an den beiden Stirnseiten des Koksofens über in etwa dem Volumen des oberhalb der Ofenfüllung ausgebildeten Gassammelraum entsprechende, vertikale Sammelräume derart abgesaugt wird, dass die Menge des Gases, das durch die Ofenfüllung senkrecht nach oben steigt, und durch den horizontalen Gassammelraum abgesaugt wird, wesentlich verringert wird und dass durch die vertikalen, an den Stirnseiten des Ofens abgezogene Gas unmittelbar in die Vorlage der Koksofenbatterie abgeleitet wird.The object is achieved according to the invention in that the gas is sucked off at the same time on the two end faces of the coke oven via vertical collecting spaces corresponding approximately to the volume of the gas collecting space formed above the furnace filling such that the amount of gas flowing through the furnace filling is vertical rises to the top, and is sucked off through the horizontal gas collecting space, is substantially reduced and that is discharged directly into the template of the coke oven battery through the vertical gas drawn off at the front sides of the furnace.
Durch das gezielte Absaugen des Gases im Bereich der Stirnseiten des Koksofens bzw. der Ofenfüllung wird die Menge des Gases, das durch die Ofenfüllung senkrecht nach oben steigt und durch den horizontalen Gassammelraum abgesaugt werden muss, wesentlich verringert. Das Gas kann nun bis zu einem gewissen Bereich in die Ofenfüllung hinein auf kurzem Wege abgesaugt und dann unmittelbar in die Vorlage abgeleitet werden. Der Anteil an flüchtigen Kohlenwasserstoffen steigt deutlich an.Through the targeted suction of the gas in the area of the front of the coke oven or the furnace filling, the amount of gas that is caused by the Furnace filling rises vertically upwards and has to be extracted through the horizontal gas collecting space, significantly reduced. The gas can now be sucked up to a certain area into the furnace filling in a short way and then discharged directly into the receiver. The proportion of volatile hydrocarbons increases significantly.
Ein gleichmässiges und während des gesamten Verkokungsprozesses sicheres Abführen des freigesetzten Gases aus dem Kokskuchen bzw. der Ofenfüllung in Richtung auf die vertikalen Sammelräume und weiter zur Vorlage wird erfindungsgemäss dadurch erreicht, dass die von den an den Stirnseiten des Koksofens abgesaugten Gasen mitgeführte Wärme zur Beheizung des aus Türkörper, Koksofenwänden und einer über Distanzstücke gehaltenen, hitzebeständigen Platte gebildeten vertikalen Sammelräume verwendet wird. Durch die gleichmässige Aufheizung des Sammelraums wird das Niederschlagen von Kondensat weitgehend verhindert. Damit wird erreicht, dass sich die Tür beinahe von selbst reinigt, so dass immer ein ausreichend grosses Volumen für das Absaugen des Gases zur Verfügung steht. Auch die Schlitze zwischen der Platte und der Ofenwandung werden auf diese Art und Weise offengehalten, so dass auch über die Höhe des Sammelraums gesehen überall Gas in den Sammelraum eindringen kann. Darüberhinaus tritt der positive Effekt ein, dass das der Vorlage zugeführte Gas ein um etwa 50° niedrigere Temperatur aufweist, als bei Vorhandensein nur des horizontalen Gassammelraums.A uniform and safe removal of the released gas from the coke cake or the furnace filling in the direction of the vertical collecting spaces and further to the presentation is achieved according to the invention in that the heat carried off by the gases extracted at the end faces of the coke oven is used to heat the is used from door body, coke oven walls and a vertical collection space formed over spacers, heat-resistant plate. The uniform heating of the collecting space largely prevents condensation from depositing. This ensures that the door almost automatically cleans itself, so that there is always a sufficiently large volume available for the suction of the gas. The slots between the plate and the furnace wall are also kept open in this way, so that gas can penetrate into the collecting space everywhere, even when viewed over the height of the collecting space. In addition, there is the positive effect that the gas supplied to the receiver has a temperature which is approximately 50 ° lower than when only the horizontal gas collecting space is present.
Die Erfindung zeichnet sich insbesondere dadurch aus, dass durch eine Erhöhung der flüssigen Kohlenwasserstoffe im Gas der Wert des gewonnenen Gases erhöht wird, wobei zugleich durch die gleichmässige Ausgarung der Kopfpartien auch eine Verbesserung und Vergleichmässigung der Gasqualität sichergestellt wird.The invention is characterized in particular by the fact that an increase in the liquid hydrocarbons in the gas increases the value of the gas obtained, and at the same time an improvement and homogenization of the gas quality is ensured by the uniform cooking of the head parts.
Weitere Einzelheiten und Vorteile des Erfindungsgegenstandes ergeben sich aus der nachfolgenden Beschreibung der zugehörigen Zeichnung, die zur Verdeutlichung des Verfahrens nachfolgend erläutert wird. Dabei handelt es sich um eine perspektivische Teilansicht einer Koksofentür mit einem auf der Innenseite ausgebildeten grossvolumigen Sammelraum. Die Figur zeigt die wesentlichen Teile einer Koksofentür, mit der in den Koksofen hineinzeigenden Seite nach oben gewandt. Der die Armaturen tragenden Türkörper ist mit 1 bezeichnet. Seitlich daran sind Dichtleisten angeordnet, die beim Einschwenken der Koksofentür am Türrahmen anliegen und dadurch zu der gewünschten Abdichtung des Koksofens gegenüber der Atmosphäre führen.Further details and advantages of the subject matter of the invention result from the following description of the accompanying drawing, which is explained below to clarify the method. This is a partial perspective view of a coke oven door with a large-volume collecting space formed on the inside. The figure shows the essential parts of a coke oven door, with the side facing the coke oven facing upwards. The door body carrying the fittings is designated by 1. Sealing strips are arranged on the side, which rest against the door frame when the coke oven door is swiveled in, thereby leading to the desired sealing of the coke oven from the atmosphere.
Auf der Innenseite des Türkörpers 1 ist der besonders ausgebildete und mit 4 bezeichnete Türstopfen angeordnet, der entsprechend weit in die Ofenkammer hineinragt und unter Belassung seit- .licher, schmaler Durchlässe für das Gas zwischen der Türfüllung und dem Türkörper 1 den grossvolumigen Sammelraum 7 ergibt. Durch den Sammelraum 7 kann das Gas vom Boden der Ofenkammer zu dem im Bereich der Decke angeordneten Steigrohr und in die Vorlage aufsteigen. Zwischen dem Türstopfen bzw. der Platte 16 und dem Türkörper 1 befindet sich eine Wärmeisolierung 8, die den Türkörper schützt und eine Abkühlung des durch den Sammelraum 7 streichenden Gases verhindert.On the inside of the door body 1, the specially designed and designated 4 door stopper is arranged, which protrudes correspondingly far into the furnace chamber and, while leaving lateral, narrow passages for the gas between the door panel and the door body 1, results in the large-volume collecting space 7. The gas can rise through the collecting space 7 from the bottom of the furnace chamber to the riser pipe arranged in the area of the ceiling and into the receiver. Between the door stopper or the
Der mit 4 bezeichnete Türstopfen ist hier durch die T-förmig ausgebildeten Distanzstücke 18, 19 und die darauf liegenden Abschnitte 29, 30, 31 der Platte 16 gebildet. Die einzelnen Abschnitte 29, 30, 31 sind mit einem gewissen Abstand zueinander angeordnet und liegen auf dem grösseren Flansch der Distanzstücke 18, 19 auf. Auf die einzelnen Abschnitte 29, 30, 31 sind Verstärkungseisen 25, 26 aufgesetzt, so dass die Platte 16 selbst aus dünnem Blech gefertigt werden kann.The door stopper designated 4 is formed here by the T-
Die Darstellung verdeutlicht, dass die Gase bei einem derart ausgebildeten vertikalen Sammelraum sehr gut in diesen abgesaugt werden können. Die einzelnen Distanzstücke 18, 19 stellen keine Behinderung für das abgesaugte bzw. abgeführte Gas dar, zumal sie im Abstand zueinander angeordnet sind. Auch auf der Druckseite, wo oben an der Tür ein Kasten zur Durchführung der Planierstange vorgesehen ist, wird der Planierkasten so ausgebildet, dass das Gas seitlich daran vorbeigeführt werden kann.The illustration shows that the gases can be extracted very well in a vertical collecting space designed in this way. The
Da die hitzebeständige Platte 16 vorzugsweise aus einem Metall bzw. aus Stahl mit einer hohen Wärmeleitfähigkeit hergestellt ist, erfolgt eine 'Wärmezufuhr vom Gas an die Ofenfüllung, so dass diese Partien nicht nur seitlich von den Heizwänden her, sondern zugleich auch über diese Platte 16 aufgewärmt und erhitzt werden. Die dadurch erzielte einwandfreie Abgarung der Kopfpartien führt zu einer Verbesserung der Gasabführung in diesem Bereich in den Sammelraum und erbringt gleichzeitig beim Koksdrücken wesentlich geringere Emissionen, da vollwertiger Koks hier ansteht.Since the heat-
