Description

Die Erfindung betrifft eine am Kokskuchenführungswagen be­festigte Absaughaube für die beim Ausbringen des Kokses aus einer Koksofenkammer auftretenden Emissionen.The invention relates to a suction hood attached to the coke cake carriage for the emissions occurring when the coke is discharged from a coke oven chamber.

Beim Ausbringen (Drücken) des Kokses aus den Koksofenkam­mern in den Koksverlade- und -löschwagen entstehen beim Zusammenbrechen des glühenden Kokskuchens Gemische aus Staub, Luft und Gas, die als aufsteigende dunkle Wolke die Atmosphäre verunreinigen und die Umgebung belästigen. Die hierbei gebildeten Gase, die durch Verbrennung von Ober­flächenkoks mit der Umgebungsluft entstehen, sind aggres­siv und wirken insbesondere in Verbindung mit Wasser korro­siv auf in der Umgebung befindliche Maschinen- und Anla­genteile.When the coke is discharged (pressed) from the coke oven chambers into the coke loading and unloading car, when the glowing coke cake collapses, mixtures of dust, air and gas are formed which, as a rising dark cloud, contaminate the atmosphere and pollute the environment. The gases formed in this process, which are generated by the combustion of surface coke with the ambient air, are aggressive and, particularly in connection with water, have a corrosive effect on machine and system parts in the vicinity.

Um ein ungehindertes Austreten dieser Emissionen in die Atmosphäre zu verhindern, ist es deshalb bereits bekannt, den Kokskuchenführungswagen, durch den das Drücken des Kokses aus der Koksofenkammer bewerkstelligt wird, mit einer Absaughaube zu versehen, durch die die auftreten­den staubbeladenen Gase abgesaugt und in der die Stäube niedergeschlagen werden sollen. Hierfür sind bereits ver­schiedene konstruktive Ausführungsformen bekannt.In order to prevent these emissions from escaping unhindered into the atmosphere, it is therefore already known to provide the coke cake carriage, which is used to push the coke out of the coke oven chamber, with a suction hood, through which the dust-laden gases that occur are extracted and in which the Dusts should be deposited. Various design embodiments are already known for this.

So werden zum Beispiel in der DE-AS 17 71 506 und der DE-PS 30 38 519 Absaughaubenkonstruktionen beschrieben, bei denen die Absaugung der staubbeladenen Gase nur durch den thermischen Auftrieb bewerkstelligt wird, der durch die hohe Temperaturdifferenz zwischen dem gedrückten glü­henden Koks und der Umgebungsluft hervorgerufen wird. Derartige Absaughaubenkonstruktionen, die auch als Ka­mine bezeichnet werden, können dabei mit Flüssigkeits­bedüsungs- und -abscheideeinrichtungen versehen sein, durch die die benetzten Staubteilchen abgeschieden und abgeführt werden können. Derartige nur die Thermik nutzende Haubensysteme sind zwar weniger aufwendig und damit wirtschaftlicher als andere Systeme, die mit Ven­tilatoren oder Gebläsen arbeiten. Nachteilig bei den bisher bekannten Konstruktionen ist jedoch, daß sie während des Drückvorganges immer nur einen Teil der Grundfläche des Koksverlade- und -loschwagens überdecken. Daher liegt, wenn beim Drücken des Kokses der Koksver­lade- und -löschwagen verfahren wird, immer ein Teil des glühenden Kokses außerhalb des Absaugquerschnittes des Haubensystems, so daß in diesem Bereich die staubbela­denen Gase ungehindert in die Atmosphäre entweichen können.For example, DE-AS 17 71 506 and DE-PS 30 38 519 suction hood constructions are described, where the extraction of the dust-laden gases is accomplished only by the thermal buoyancy caused by the high temperature difference between the pressed glowing coke and the ambient air. Suction hood constructions of this type, which are also referred to as chimneys, can be provided with liquid spraying and separating devices through which the wetted dust particles can be separated and removed. Such hood systems that only use thermals are less complex and therefore more economical than other systems that work with fans or blowers. A disadvantage of the previously known constructions, however, is that they always cover only a part of the base area of the coke loading and unloading carriage during the pressing process. Therefore, if the coke loading and unloading car is moved when the coke is pressed, part of the glowing coke is always outside the suction cross-section of the hood system, so that the dust-laden gases can escape into the atmosphere unhindered in this area.

Aus der DE-OS 29 52 179 ist zwar eine Haubenkonstruktion bekannt, bei der die Haube zumindest teilweise die Auf­nahmefläche des Koksverlade- und -löschwagens für den glühenden Koks überdeckt. Die Haube ist hierbei jedoch mit dem Koksverlade- und -löschwagen fest verbunden und mit ihm bis zum Löschturm verfahrbar, was eine aufwen­dige und damit teure und unwirtschaftliche Konstruktion bedingt.From DE-OS 29 52 179 a hood construction is known in which the hood at least partially covers the receiving surface of the coke loading and unloading carriage for the glowing coke. However, the hood is firmly connected to the coke loading and unloading car and can be moved with it to the extinguishing tower, which requires a complex and therefore expensive and uneconomical construction.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Absaughaubenkonstruktion zu schaffen, die einerseits ein ungehindertes Entweichen der beim Ausbringen des Kokses aus einer Koksofenkammer auftretenden Emissionen in die Atmosphäre weitestgehend ausschließt und die sich andererseits durch eine möglichst einfache und da­mit wirtschaftliche Bauweise auszeichnet.The invention is therefore based on the object of creating a suction hood construction, on the one hand an unhindered escape of the emissions occurring when the coke is discharged from a coke oven chamber into the atmosphere as far as possible and which, on the other hand, is characterized by the simplest and therefore most economical construction.

Diese Aufgabe wird gelöst durch eine am Kokskuchenfüh­rungswagen befestigte Absaughaube, die erfindungsgemäß dadurch gekennzeichnet ist, daß dieselbe aus zwei oder mehreren Kaminen zusammengesetzt ist und insgesamt einen Absaugquerschnitt aufweist, der größer ist als die Grund­fläche des verwendeten Koksverlade- und -löschwagens, wobei die einzelnen Kamine zu den dazugehörigen Schlo­ten hin eine Verjüngung aufweisen.This object is achieved by a suction hood attached to the coke cake carriage, which according to the invention is characterized in that it is composed of two or more chimneys and has an overall suction cross section which is larger than the base area of the coke loading and unloading car used, the individual chimneys have a taper towards the associated chimneys.

Durch die Anwendung der erfindungsgemäßen Konstruktion wird sichergestellt, daß sich während des gesamten Drück­vorganges der im Koksverlade- und -löschwagen befind­liche Koks immer unterhalb eines Absaugquerschnittes eines Kamins befindet, so daß auch beim Verfahren des Koksverlade- und -loschwagens keine staubbeladenen Gase in die Atmosphäre gelangen können. Die Zahl der Kamine, aus denen die erfindungsgemäße Absaughaube zusammenge­setzt ist, richtet sich selbstverständlich nach den praktischen Gegebenheiten, insbesondere natürlich nach der Menge der anfallenden staubbeladenen Gase und der Länge der Strecke, die vom Koksverlade- und -löschwa­gen während des Drückvorganges durchfahren werden muß. Es muß hierbei in jedem Falle sichergestellt werden, daß diese Strecke vom Anfangs- bis zum Endpunkt von den Ab­saugquerschnitten der einzelnen Kamine überdeckt ist.The use of the construction according to the invention ensures that the coke in the coke loading and unloading car is always below a suction cross section of a chimney during the entire pressing process, so that no dust-laden gases enter the atmosphere even when the coke loading and unloading car is being moved can. The number of chimneys from which the suction hood according to the invention is made up depends, of course, on the practical circumstances, in particular, of course, on the amount of dust-laden gases and the length of the route which the coke loading and unloading car has to travel through during the pressing process. In any case, it must be ensured that this distance from the start to the end point is covered by the suction cross-sections of the individual chimneys.

Durch die Ausnutzung der Thermik entfallen bei der er­findungsgemäßen Vorrichtung in den hintereinander ge­schalteten Kaminen zusätzliche mechanische Saugvorrich­tungen. Da die einzelnen Kamine zum Schlot hin eine un­terschiedliche Verjüngung aufweisen können, ist es mög­lich, die Sogwirkung der Thermik, die ja abhängig ist vom Grad der Verjüngung, dem Anfall der staubbeladenen Gase anzupassen. Hierbei wird zweckmäßigerweise die Ver­jüngung der Kamine umso größer, je größer der Abstand des jeweiligen Kamins von der gedrückten Koksofenkammer ist. Dadurch wird sichergestellt, daß auch bei schwächer werdender Emission eine vollständige Absaugung der staub­beladenen Gase gegeben ist.By utilizing the thermal, additional mechanical suction devices are omitted in the device according to the invention in the chimneys connected in series. Since the individual chimneys can have a different taper towards the chimney, it is possible to adapt the suction effect of the thermals, which depends on the degree of taper, to the amount of dust-laden gases. In this case, the tapering of the chimneys is expediently greater, the greater the distance of the respective chimney from the pressed coke oven chamber. This ensures that there is complete extraction of the dust-laden gases even when the emissions become weaker.

Die Anwendung der erfindungsgemäßen Absaughaube ist be­sonders vorteilhaft bei herkömmlichen langen und flachen Koksverlade- und -löschwagen mit schrägem Boden.The use of the suction hood according to the invention is particularly advantageous in the case of conventional long and flat coke loading and unloading vehicles with an inclined bottom.

Weitere Einzelheiten der Erfindung ergeben sich aus den vorliegenden Unteransprüchen und sollen nachfolgend an Hand der Abbildungen erläutert werden, die ein Ausfüh­rungsbeispiel betreffen. Hierbei zeigen:

  • Fig. 1 eine vereinfachte schematische Darstellung einer erfindungsgemäßen Absaughaube und
  • Fig. 2 einen Schnitt entlang der Linie II - II′ in Fig. 1.
Further details of the invention emerge from the present subclaims and are to be explained below with reference to the figures which relate to an exemplary embodiment. Here show:
  • Fig. 1 is a simplified schematic representation of an exhaust hood according to the invention and
  • Fig. 2 shows a section along the line II - II 'in Fig. 1st

Die in Fig. 1 dargestellte Absaughaube ist aus den zwei Kaminen 1 und 2 zusammengesetzt, die über das Zwischen­stück 3 miteinander verbunden sind. Unter den Kaminen 1 und 2 fährt während des Drückvorganges der Koksverlade- und -löschwagen 4 entlang. Dieser nimmt beim Beginn des Drückvorganges mit seinem vorderen Kopfende die Stellung A ein, während sich bei Beendigung des Druckvorganges das vordere Kopfende in Stellung B befindet. Die zu drückende Koksofenkammer trägt hierbei das Bezugszei­chen 5. Bei Beginn des Drückvorganges (Stellung A) wer­den die staubbeladenen Gase im wesentlichen nur durch den ersten Kamin 1 abgesaugt. Im weiteren Verlauf des Druckvorganges wird dann der Koksverlade- und -lösch­wagen 4 immer mehr in Richtung auf B hin verfahren, so daß die Absaugung der staubbeladenen Gase in zunehmen­dem Maße auch durch den Kamin 2 erfolgt, wie dies durch die Pfeile in Fig. 1 angedeutet wird. Die Stellung des Koksverlade- und -löschwagens 4 bei Beginn des Drück­vorganges ist in der Abbildung durch die unterbrochen gezeichneten Linien markiert, während die Stellung bei Beendigung des Drückvorganges durch die ausgezogenen Linien markiert ist. Man erkennt hieraus, daß sich wäh­rend des gesamten Drückvorganges die gesamte mit glühen­dem Koks bedeckte Grundfläche des Koksverlade- und -löschwagens 4 immer unterhalb der Absaugquerschnitt der Kamine 1 und/oder 2 befindet. Ein Entweichen der staubbeladenen Gase in die Atmosphäre ist deshalb prak­tisch ausgeschlossen.The suction hood shown in Fig. 1 is composed of the two chimneys 1 and 2, which are connected to one another via the intermediate piece 3. Under the chimneys 1 and 2, the coke loading and fire engine 4 along. This assumes position A with its front head end at the start of the printing process, while the front head end is in position B at the end of the printing process. The coke oven chamber to be pressed bears the reference number 5. At the beginning of the pressing process (position A), the dust-laden gases are essentially extracted only through the first chimney 1. In the further course of the printing process, the coke loading and unloading carriage 4 is then moved more and more towards B, so that the dust-laden gases are also increasingly extracted through the chimney 2, as indicated by the arrows in FIG. 1 becomes. The position of the coke loading and unloading carriage 4 at the beginning of the pressing process is marked in the figure by the broken lines, while the position at the end of the pressing process is marked by the solid lines. It can be seen from this that the entire base area of the coke loading and unloading carriage 4, which is covered with glowing coke, is always below the suction cross section of the chimneys 1 and / or 2 during the entire pressing process. Escape of the dust-laden gases into the atmosphere is practically impossible.

Die Darstellung in Fig. 1 läßt ferner erkennen, daß die Kamine 1 und 2 zu den dazugehörigen Schloten 6 hin eine Verjüngung aufweisen. Hierbei ist diese Verjüngung beim Kamin 2 größer als beim Kamin 1. Dadurch wird der Tat­sache Rechnung getragen, daß mit zunehmendem Abstand von der Koksofenkammer 5 die Menge der aus dem glühen­den Koks aufsteigenden staubbeladenen Gase abnimmt, wes­halb die Sogwirkung im Kamin 2 größer sein muß als im Kamin 1. In den Schloten 6 ist jeweils eine Sprüh- und Abscheideeinrichtung 7 vorgesehen, durch die die mit den heißen Gasen aufsteigenden Stäube abgeschieden werden. Außerdem weisen die Schlote 6 zur Verbesserung der Sog­wirkung an ihrem oberen Ende eine diffusorartige Erwei­terung 8 auf.The illustration in FIG. 1 also shows that the chimneys 1 and 2 have a taper towards the associated chimneys 6. This taper in the chimney 2 is larger than in the chimney 1. This takes into account the fact that with increasing distance from the coke oven chamber 5 the amount of dust-laden gases rising from the glowing coke decreases, which is why the suction effect in the chimney 2 must be greater than in the Chimney 1. In the chimneys 6, a spraying and separating device 7 is provided, through which the dusts rising with the hot gases are separated. In addition, the chimneys 6 have a diffuser-like extension 8 at their upper end to improve the suction effect.

Fig. 2 zeigt einen Schnitt entlang der Linie II - II′ durch die in Fig. 1 dargestellte Absaughaube.Fig. 2 shows a section along the line II - II 'through the suction hood shown in Fig. 1.
