Description
Vorrichtung zum Unschädlichmachen der Gase, die aus Beschickungsbunkern von Elektroöfen austreten Es ist bekannt, bei Elektroöfen Bunker über den Öfen vorzusehen und Beschickungsgut aus den Bunkern dem Ofen durch Fallrohre zuzuführen. Unter ungünstigen Bedingungen können sich in den Bunkern Gase bilden. Beispielsweise können aus dem Ofen Gase durch die Fallrohre in die Bunker gelangen, aus diesen in die Ofenhalle entweichen und die Bedienungsmannschaft belästigen oder sogar gesundheitlich schädigen.Device for rendering the gases harmless from charging bunkers Escape from electric ovens It is known to provide bunkers over the ovens in electric ovens and feeding the load from the bunkers to the furnace through downpipes. Under unfavorable Conditions can form gases in the bunkers. For example, from the Furnace gases pass through the downpipes into the bunker, from these into the furnace hall escape and annoy the operating crew or even damage their health.
Die Erfindung hat es sich zum Ziel gesetzt, eine Vorrichtung zu schaffen, durch die die Gase unschädlich gemacht werden können, die aus Beschickungsbunkern von Elektroöfen, bei denen eine Behandlung des Beschickungsgutes in den Beschickungsbunkern mit den Ofengasen nicht erfolgen soll, austreten. Dieses Ziel wird gemäß der Erfindung dadurch erreicht, daß auf der einen Seite der Bunkeröffnung eine Reihe von Düsen zur Erzeugung eines Luftschleiers und auf der anderen Seite einTrichter zumAuffangen und Ableiten des Luftstromes vorgesehen ist.The invention has set itself the goal of creating a device through which the gases can be rendered harmless from the feed bunkers of electric furnaces, in which the loading material is treated in the loading bunkers should not take place with the furnace gases. This aim is achieved according to the invention achieved in that on one side of the bunker opening a number of nozzles to create an air curtain and on the other side a funnel to collect it and diverting the air flow is provided.
Es ist zwar bereits bekannt, bei solchen Beschikkungsbunkern und Vorbehandlungsöfen, in denen eine Vorbehandlung des Beschickungsgutes durch die Ofengase des Elektroofens erfolgt, Luft zur Verbrennung der Ofengase zuzuführen und die Gase abzusaugen. Jedoch bezieht sich die Erfindung nur auf die Unschädlichmachung von aus solchen Bunkern austretenden Gasen, in denen eine Vorbehandlung des Beschickungsgutes nicht vorgesehen ist.It is already known that in such charging bunkers and pretreatment ovens, in which a pretreatment of the load by the furnace gases of the electric furnace takes place to supply air for combustion of the furnace gases and suck out the gases. However the invention relates only to the rendering of such bunkers harmless escaping gases in which a pretreatment of the load is not intended is.
In der Zeichnung ist in Form eines Ausführungsbeispiels eine die Erfindungsmerkmale aufweisende Vorrichtung dargestellt.In the drawing, in the form of an exemplary embodiment, one is the features of the invention having device shown.
F i g. 1 zeigt im Vertikalschnitt einen Teil eines Elektroofens mit Bunker, F i g. 2 eine Draufsicht des Bunkers.F i g. 1 shows a part of an electric furnace in vertical section Bunker, F i g. 2 is a top view of the bunker.
Über dem Elektroofen 1, der mit Elektroden 2 beheizt wird, sind Bunker 3 angeordnet, die durch Fallrohre 4 mit dem Ofen 1 verbunden sind. Das Beschickungsgut 5 wird mittels nicht dargestellter Fördermittel durch die Bunkeröffnung 6 in den. Bunker 3 gebracht, von wo es durch das Fallrohr 4 in den Ofen 1 gelangt. Durch das Fallrohr 4 können Gase, die bei den im Ofen 1 stattfindenden Reaktionen erzeugt werden, in den Bunker 3 aufsteigen. Damit die Gase nicht durch die Bunkeröffnung 6 entweichen und in der Ofenhalle zu Unträglichkeiten führen, wird durch die Rohrleitung 7 herangeführte Preßluft mittels der Düsen 8 als Luftschleier über die Bunkeröffnung 6 hinweg geblasen. Der Luftstrom gibt nicht nur den Gasen eine bestimmte Bewegungsrichtung und erleichtert so ihr Abführen, sondern er bewirkt auch sofort eine starke Verdünnung der Gase, die ihre Schädlichkeit vermindert und die Gefahr der Bildung einer explosiblen Mischung praktisch beseitigt. Der Luftstrom wird durch Leitbleche 9 begrenzt, durch den Trichter 10 aufgefangen, zu der Leitung 11 geführt und in dieser zum Kamin geleitet. Erforderlichenfalls kann in die Leitung 11 zur Verstärkung des Saugzuges ein Ventilator vorgesehen werden. Die Leitbleche 9 lassen die Bunkeröffnung 6 frei, um das Beschicken des Bunkers 3 zu ermöglichen.Above the electric furnace 1, which is heated with electrodes 2, there are bunkers 3, which are connected to the furnace 1 by downpipes 4. The load 5 is by means of not shown funding through the bunker opening 6 in the. Bunker 3 brought from where it passes through the downpipe 4 into the furnace 1. By the Downpipe 4 can contain gases that are generated in the reactions taking place in the furnace 1 climb into bunker 3. So that the gases do not pass through the bunker opening 6 escape and lead to incompatibilities in the furnace hall, is through the pipeline 7 brought compressed air by means of the nozzles 8 as an air curtain over the bunker opening 6 blown away. The air flow not only gives the gases a certain direction of movement and thus facilitates their removal, but it also immediately causes a strong dilution of gases, which reduces their harmfulness and the risk of the formation of an explosive Mixture practically eliminated. The air flow is limited by baffles 9, through caught the funnel 10, led to the line 11 and passed in this to the chimney. If necessary, a fan can be installed in the line 11 to increase the induced draft are provided. The baffles 9 leave the bunker opening 6 free to allow loading of the bunker 3 to enable.
