  • Fig. 2 is a plan view and
  • Fig. 3 shows a partial section.

Auf einem Tieflader 1 ist der doppelwandige Kokslöschbehälter 2 ange­ordnet. Die innere Wand des Kokslöschbehälters wird von Schleiß­platten 3 gebildet, und zwar sowohl an den Wänden 4 als auch dem Boden 5. Die Öffnung für den Wasser- und Koksauslaß ist mit einer Klappe 6 von außen verschlossen. Zusätzlich ist in der Öffnung ein Gitterrost 7 vorgesehen. Die Löschwasserzufuhr für die Tauchlöschung erfolgt über die Zufuhrrohre 8. Von den Wasserzufuhrrohren 8 führt ein Lei­tungssystem 9, 10, 11 zu den Wassereintrittsöffnungen 12, 13 und 14.The double-walled coke extinguishing container 2 is arranged on a low loader 1. The inner wall of the coke extinguishing container is formed by wear plates 3, both on the walls 4 and the bottom 5. The opening for the water and coke outlet is closed with a flap 6 from the outside. In addition, a grating 7 is provided in the opening. The supply of extinguishing water for the immersion extinguishing takes place via the supply pipes 8. A pipe system 9, 10, 11 leads from the water supply pipes 8 to the water inlet openings 12, 13 and 14.

Gemäß der Erfindung sind die Wassereintrittsöffnungen 12, 13, 14 im Behälterboden 5 nur in dem Teilbereich des Bodens angeordnet, der sich von der Mittelebene 15 an ansteigend zu einer Behälterwand er­streckt. Die Achsen der Wassereintrittsöffnungen 13 stehen dabei lot­recht zum Behälterboden 5. Es empfiehlt sich, die Wassereintritts­öffnungen 13 durch im Abstand davon angeordnete Abdeckplatten zu schützen, um sowohl beim Füllen des Löschbehälters als auch während des Löschvorganges ein Verstopfen derselben zu verhindern. Ferner sich nach einem weiteren Merkmal der Erfindung die Wassereintritts­öffnungen 12 in dem Teilbereich der Behälterwandungen angeordnet, die den Behälterboden im ansteigenden Bereich ab der Mittelebene 15 seitlich begrenzen. In der Höhe erstreckt sich diese Zone der Seiten­wand mit den Wassereintrittsöffnungen 12 etwa bis zur Höhe der Ober­kante 16 des Behälterbodens. Die Achsen der Eintrittsöffnungen 12 stehen senkrecht zur Behälterwand. Zur Erfindung gehört ferner die Anordnung von Wassereintrittsöffnungen 14 in unmittelbarer Nähe der Oberkante 16 des Behälterbodens 5, wobei deren Achse eine Neigung aufweist, die der des Behälterbodesn 5 entspricht. Die Wasserein­trittsöffnungen 12, 13, 14 sind mit dem Wasserzufuhrrohr 8 über ein Leitungssystem 9, 10, 11 verbunden.According to the invention, the water inlet openings 12, 13, 14 in the container base 5 are arranged only in the partial region of the base which extends from the central plane 15 to a container wall. The axes of the water inlet openings 13 are perpendicular to the container bottom 5. It is advisable to protect the water inlet openings 13 by cover plates arranged at a distance therefrom, in order to prevent them from becoming blocked both when filling the extinguishing container and during the extinguishing process. Furthermore, according to a further feature of the invention, the water inlet openings 12 are arranged in the partial region of the container walls, which laterally delimit the container base in the rising region from the central plane 15. The height of this zone of the side wall with the water inlet openings 12 extends approximately to the height of the upper edge 16 of the container bottom. The axes of the inlet openings 12 are perpendicular to the container wall. The invention also includes the arrangement of water inlet openings 14 in the immediate vicinity of the upper edge 16 of the container base 5, the axis of which has an inclination which corresponds to that of the container base 5. The water inlet openings 12, 13, 14 are connected to the water supply pipe 8 via a line system 9, 10, 11.

Die gemäß der Erfindung ausgestatteten Einpunktlöschwagen sind mit Vorteil anwendbar bei jeder Art von Kokskammergrößen. Besondere Vor­teile ergeben sich jedoch bei Koksofenbatterien, mit einer Kammer­kapazität, die pro Brand eine Koksmenge von 20 t und darüber, lie­ fern. Das Fassungsvermögen des Behälters sollte dabei so gewählt werden, daß es um 40 bis 100 % größer ist als das einzufüllende Koksvolumen. Die Obergre nze kann dabei je nach Geometrie des Behäl­ters überschritten werden. In jedem Fall ist die Größe so zu bemes­sen, daß die Bewegungen des Kokses während des Löschvorganges inner­halb des Behälters erfolgen. Durch die seitlich begrenzte Wasserzu­fuhr wird durch den beim Tauchvorgang plötzlichen Wassereinfall und der damit verbundenen Dampfbildung eine Egalisierung der Schüttgut­oberfläche erzielt, so daß für die Beregnung eine im wesentlichen ebene Schüttgutoberfäche vorhanden ist. Dies ist von Vorteil im Hinblick auf eine gleichmäßige Abkühlung und Durchnässung des Kokses. Bei Anwendung des erfindungsgemäßen Kokslöschbehälters konnten bei einer Koksmenge pro Ofenkammer von 43 t und einem Behälterquerschnitt von 6 cx 6 m² beispielsweise folgende Werte erzielt werden. Bei einer Wassermenge für den Tauchlöschvorgang von ca. 1,5 cbm/t Koks konnte der Löschvorgang innerhalb von 30 sec beendet werden. Der Koks wies nach dem Löschvorgang eine Feuchtigkeit von 2 % auf. Eine Nesterbil­dung innerhalb des Haufwerkes war nicht vorhanden.The single-point fire-fighting vehicles equipped according to the invention can advantageously be used with any type of coke chamber size. However, there are special advantages with coke oven batteries with a chamber capacity that amounts to 20 tons and more of coke per fire remote. The capacity of the container should be chosen so that it is 40 to 100% larger than the coke volume to be filled. The upper limit can be exceeded depending on the geometry of the container. In any case, the size must be such that the movements of the coke during the extinguishing process take place inside the container. Due to the laterally limited water supply, a leveling of the bulk material surface is achieved due to the sudden incidence of water during the dipping process and the steam formation associated therewith, so that an essentially flat bulk material surface is available for the irrigation. This is advantageous with regard to a uniform cooling and wetting of the coke. When using the coke extinguishing container according to the invention, for example, the following values could be achieved with a coke quantity per furnace chamber of 43 t and a container cross section of 6 cx 6 m². With a quantity of water for the immersion extinguishing process of approx. 1.5 cbm / t coke, the extinguishing process could be ended within 30 seconds. The coke had a moisture content of 2% after the extinguishing process. There was no formation of nests within the pile.
