Description

Die Erfindung betrifft eine Koksofenbatteriehalle gemäß dem Oberbegriff des Hauptanspruches.The invention relates to a coke oven battery hall according to the preamble of the main claim.

Es sind zahlreiche Koksofenbatteriehallen bekannt, die unter Besprühen der Koksofen-Emissionen mit Wasser, durch Waschen der Emissionen in speziellen Waschern und Absaugen der gewaschenen Gase über Ventilatoren eine Abführung dieser Rauchgase ins Freie in gereinigter Form anstreben. Es kommt indessen bei den bekannten Hallen im allgemeinen zu Stauungen dieser Rauchgase unter dem Hallendach mit der Folge, daß grobe und feine Staubkörner in der Halle von der Decke herabfallen und den Aufenthalt in der Halle unzumutbar machen.Numerous coke oven battery halls are known which, by spraying the coke oven emissions with water, by washing the emissions in special washers and extracting the washed gases via fans, aim to discharge these smoke gases into the open in a cleaned form. In the known halls, however, these smoke gases generally stagnate under the roof of the hall, with the result that coarse and fine dust particles in the hall fall off the ceiling and make the stay in the hall unreasonable.

Aus: der DE-B 2 306 057 ist eine Koksofenbatteriehalle der gattungsgemäßen Art bekannt ; dies gilt auch für einen Dachaufbau mit einer gekrümmten Ablauffläche und einer weiteren gekrümmten Ablauffläche am oberen Ende der Trennwand. Das Herabfallen grober und feiner Staubkörner im Bereich zwischen den Ofentüren und der Trennwand wird allerdings nicht hinreichend unterbunden.From: DE-B 2 306 057 a coke oven battery hall of the generic type is known; this also applies to a roof structure with a curved drain surface and a further curved drain surface at the upper end of the partition. The falling down of coarse and fine dust grains in the area between the furnace doors and the partition is not sufficiently prevented.

Aus der US-A 3 972 782 ist eine weitere Koksofenbatteriehalle der gattungsgemäßen Art mit gekrümmter Ablauffläche im Dach und einer in ihrem oberen Bereich in Richtung auf die Ofentüren vorspringen Trennwand bekannt. Der zwischen diesem Vorsprung und der Dachwölbung entstehende Düseneffekt erweist sich aufgrund von Verwirbelungen jedoch als für die Vermeidung von Staubbelästigungen unzureichend und jener konkreter Ausführung sogar schädlich.From US-A 3 972 782 a further coke oven battery hall of the generic type with a curved drainage surface in the roof and a partition projecting in its upper area in the direction of the oven doors is known. However, due to turbulence, the nozzle effect that arises between this protrusion and the roof curvature proves to be inadequate to avoid dust nuisance and even harmful to that specific design.

Die Erfindung löst die Aufgabe, die Rauchgase, die insbesondere beim Abheben der Ofentüren und Stoßen des Kokskuchens freiwerden, vollständig und unter Vermeidung der vorstehend aufgezeigten Störungen in gereinigter Form aus der Halle abzuführen. Diese Aufgabe wird durch die Kombination der Merkmale einer Koksofenbatteriehalle gemäß Anspruch 1 gelöst. Die Merkmale gemäß den Ansprüchen 2 bis' 10 betreffen besonders vorteilhafte Ausführungsformen der Halle gemäß Anspruch 1.The invention solves the problem of completely removing the flue gases, which are released in particular when lifting the oven doors and pushing the coke cake, out of the hall while avoiding the disturbances indicated above. This object is achieved by the combination of the features of a coke oven battery hall according to claim 1. The features according to claims 2 to '10 relate to particularly advantageous embodiments of the hall according to Claim. 1

Mit der erfindungsgemäßen Ausführungsform einer Koksofenbatteriehalle wird erreicht, daß die Rauchgase zufolge der strömungstechnischen günstigen baulichen Voraussetzungen mit hoher Geschwindigkeit zu den Waschern und den diesen nachgeschalteten Ventilatoren abgeführt werden, wobei keine Stauungen oder Verwirbelungen der Gase und Dämpfe unter dem Hallendach mit all ihren nachteiligen Folgen auftreten.With the embodiment of a coke oven battery hall according to the invention it is achieved that the flue gases are discharged to the washers and the fans connected downstream at high speed due to the aerodynamically favorable structural conditions, with no congestion or swirling of the gases and vapors under the roof of the hall with all their disadvantageous consequences .

Die Besprühung und Waschung der Rauchgase in einem Wascher sowie ihre Abführung über einen Ventilator sind aus der DE-B-23 06 057 bereits bekannt.The spraying and washing of the flue gases in a washer and their removal via a fan are already known from DE-B-23 06 057.

Die strömungstechnischen Voraussetzungen für die erfolgreiche Abführung der Rauchgase lassen sich spürbar verbessern durch die baulichen Maßnahmen der Ansprüche 2 und 3. Dabei ist die leichte Auswölbung der Trennwand 10 von ganz besonderer Wirksamkeit auf die störungsfreie Abströmung der Gase. Keinesfalls darf diese Auswölbung eine deutlich hervorstehende Nase aufweisen, wie sie in der Zeitschrift « Metal Producing •, Februar 1979, Seite 47, offenbar ist, vielmehr soll es sich um einen « weichen » Bogen handeln. Eine scharfe Nase verursacht erhebliche Strömungsabrisse und Verwirbelungen der Rauchgase unter dem Hallendach, so daß eine zügige Abfuhr der Gase eher gestört als begünstigt wird.The fluidic requirements for the successful removal of the flue gases can be noticeably improved by the structural measures of claims 2 and 3. The slight curvature of the partition 10 is particularly effective for the trouble-free outflow of the gases. Under no circumstances should this bulge have a clearly protruding nose, as is evident in the magazine “Metal Producing •, February 1979, page 47, rather it should be a“ soft ”bow. A sharp nose causes considerable stalls and swirling of the flue gases under the roof of the hall, so that a rapid removal of the gases is disturbed rather than favored.

Die Ausbiegung des unteren Teiles der Trennwand etwa in halber Höhe des Löschwagens bewirkt die Ausbildung eines Luftströmungskanals und somit ein günstiges, nämlich ungebremstes und beschleunigtes Hineinströmen von Frischluft in die im unteren Bereich weitgehend offene Halle, die im übrigen an ihren Stirnseiten nach Möglichkeit völlig geschlossen sein kann, z. B. falls die Einwirkung starker Winde auf die Halle zu befürchten ist.The bending of the lower part of the partition approximately half way up the fire truck causes the formation of an air flow channel and thus a favorable, namely unchecked and accelerated flow of fresh air into the largely open hall in the lower area, which, moreover, is completely closed on the front sides if possible can, e.g. B. if the impact of strong winds on the hall is to be feared.

Es liegt auf der Hand, daß seitlich auf die Halle auftreffende Winde die gewünschte störungsfreie Abführung der Rauchgase empfindlich stören können. Dieser Gefahr begegnet die Erfindung mit Trennwänden gemäß den Ansprüchen 8 bis 10. Falls diese Trennwände im Abstand von je etwa 5-10 Öfen in das Hallendach eingezogen sind, so bilden sie über ihre Schutzwirkung vor Seitenwinden hinaus mit den beiden gekrümmten Leitblechen nahezu quadratische Kanäle, die eine besonders wirbelfreie und beschleunigte Abströmung der Rauchgase bewirken. Zur Einsparung von Waschern und Ventilatoren empfiehlt es sich, für eine größere Anzahl von nebeneinanderliegenden Öfen nur einen Wascher und einen Ventilator vorzusehen. Es kann auch ausreichend sein, an mehrere Wascher nur einen Ventilator anzuschließen.It is obvious that the winds hitting the side of the hall can seriously disrupt the desired trouble-free removal of the flue gases. The invention counters this danger with partitions according to claims 8 to 10. If these partitions are drawn into the hall roof at intervals of about 5-10 ovens, they form, with their two curved guide plates, almost square channels in addition to their protective effect against side winds, which cause a particularly swirl-free and accelerated outflow of the flue gases. To save washers and fans, it is advisable to provide only one washer and one fan for a larger number of stoves lying side by side. It may also be sufficient to connect only one fan to several washers.

Weitere Ziele, Merkmale, Vorteile und Anwendungsmöglichkeiten der vorliegenden Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispiels anhand der Figur.Further objectives, features, advantages and possible uses of the present invention result from the following description of an exemplary embodiment with reference to the figure.

Die Fläche 1 veranschaulicht eine Seitenansicht der Batterie mit der Bühne 2 für den Koksofenführungswagen 3, über den der gestoßene Koks in den Löschwagen 4 auf Löschgleis 4a übergeführt wird.The area 1 illustrates a side view of the battery with the stage 2 for the coke oven carriage 3, via which the pushed coke is transferred to the fire truck 4 on the fire track 4a.

Das Hallendach 5 beginnt frei oder fest montiert auf der türseitigen Ofenkante der Batterie an der sogenannten Koksseite und geht an der anderen Dachkante 6 in die geschlossene Seitenwand 7 über, die an den Wascher 16 praktisch gasdicht anschließt. Eine weitere Abstützung des Daches erfolgt durch die Wand oder den Pfeiler (Abstützung) 8, hinter welchen - hier nicht dargestellt - der Ventilator außerhalb der Halle angeordnet ist. Ziffer 10 kennzeichnet die Trennwand, Ziffer 11 das mittlere Leitblech und Ziffer 12 das obere Leitblech. Die gestrichelt gezeichnete Linie 13 zeigt den Dachverlauf, falls das Dach von Leitblech 12 gebildet wird und dadurch sehr niedrig gehalten sein kann, z. B. um 3 bis maximal 4,5 m die Ofendecke überragt. Ebenso kann das Dach die Funktion des Leitbleches 12 übernehmen, wenn es die entsprechende Form aufweist und im wesentlichen frei von störenden Strömungsunterbrechungen ist.The hall roof 5 begins freely or permanently mounted on the door-side oven edge of the battery on the so-called coke side and merges with the other roof edge 6 into the closed side wall 7, which connects to the washer 16 practically gas-tight. The roof is further supported by the wall or the pillar (support) 8, behind which - not shown here - the fan is arranged outside the hall. Number 10 identifies the separator wall, number 11 the middle baffle and number 12 the upper baffle. The dashed line 13 shows the course of the roof if the roof is formed by baffle 12 and can be kept very low, z. B. protrudes from the furnace ceiling by 3 to a maximum of 4.5 m. Likewise, the roof can take over the function of the guide plate 12 if it has the appropriate shape and is essentially free of disturbing flow interruptions.

Durch diese Dimensionierung entspricht die Höhe des Hallendaches ab Ofendecke etwa dem Abstand zwischen Ofentüren und Wand 10, so daß günstige statische Verhältnisse vorliegen.Due to this dimensioning, the height of the hall roof from the furnace ceiling corresponds approximately to the distance between the furnace doors and wall 10, so that favorable static conditions are present.

Die schraffierte Fläche veranschaulicht eine Trennwand 17 mit den erforderlichen Schlitzen 14 für die ungehinderte Durchfahrt des Leitbleches 11, falls dieses auf dem Koksofenführungswagen 3 montiert ist. - Diese Schlitze erübrigen sich, falls die Leitbleche 11 fest zwischen den Trennwänden installiert sind. - Wenn aber das Leitblech 11 auf dem Koksofenführungswagen 3 aufgesetzt ist, besitzt es im allgemeinen nur die Breite von 5-10 Koksöfen und fährt mit dem Koksofenführungswagen 3 längs den Koksofentüren auf der Bühne 2. Jedenfalls bildet das Leitblech 11 für die Abführung der Rauchgase zum Zeitpunkt des Ausstoßens des Kokskuchens mit dem Leitblech 12 einerseits und dem oberen, gekrümmten Teil der Wand 10 zwei nahezu quadratische Kanäle, wodurch, die Abströmung der Gase und Dämpfe beschleunigt wird. Unterstützt wird der Abströmungseffekt durch eine allmähliche Verringerung des Abstandes zwischen den Leitblechen 11 und 12. Ergänzend sei bemerkt, daß die Breite der Trennwand 10 sowie des Leitbleches 12 der Länge der Halle entspricht. Zur Verbesserung der Abströmung der Emissionen dient im übrigen die Düse 15 für z. B. Wasser. Weitere (Wasser)-düsen sind empfehlenswert.The hatched area illustrates a partition 17 with the necessary slots 14 for the unhindered passage of the guide plate 11 if it is mounted on the coke oven carriage 3. - These slots are unnecessary if the baffles 11 are firmly installed between the partitions. - But if the baffle 11 is placed on the coke oven carriage 3, it generally has only the width of 5-10 coke ovens and drives the coke oven carriage 3 along the coke oven doors on the stage 2. In any case, the baffle 11 forms for the removal of the flue gases Time of ejection of the coke cake with the guide plate 12 on the one hand and the upper, curved part of the wall 10 two almost square channels, which accelerates the outflow of gases and vapors. The outflow effect is supported by a gradual reduction in the distance between the guide plates 11 and 12. In addition, it should be noted that the width of the partition 10 and the guide plate 12 corresponds to the length of the hall. To improve the outflow of emissions, the nozzle 15 is used for z. B. water. Additional (water) nozzles are recommended.
