    Verfahren und Vorrichtung zur Entfernung und Weiterbeförderung   von Gichtstaub 
 EMI1.1 
 



   Der Arbeitsweise der Hochöfen und ähnlicher Schachtöfen haftet der Nachteil an, dass mit dem Gasstrom nennenswerte Mengen der Beschickung den Öfen in Form von Staub   entführt   werden, der sich in den rohgasführenden Rohrleitungen und   Staubabscheidern   zum grössten Teil wieder ablagert. 



  Die Entfernung dieses   Gichtstaubes   geschah bisher bekanntlich durch Öffnen von Klappenventilen, die im Boden der Staubabscheider sowie auf der ganzen Länge unterhalb der Rohgasleitungen angebracht sind. Auf diese Weise gelangt der Staub aus den Staubabscheidern unmittelbar in offene Eisenbahn-

Zur Erläuterung des Arbeitsvorganges nach der Erfindung ist in der Zeichnung ein Ausführungsbeispiel einer dazu dienenden Vorrichtung dargestellt. Fig. 1 zeigt einen Aufriss einer derartigen Anlage, 
 EMI2.1 
 Vorrichtung dar. 



   Eine Rohrleitung b ist zur Zuleitung des für die Förderung des Gichtstaubes bestimmten Ofengases vorgesehen. Die Leitung b ist durch mehrere Verbindungsrohre i mit einer Leitung e verbunden, die zur Förderung des Staubes bestimmt ist. In jede Verbindungsleitung i ist ein Absperrorgan a und eine Strahlpumpe c eingeschaltet. Letztere stehen unter Zwischenschaltung von   Durchgangshähnen     d   mit den Rohgasleitungen   h   in Verbindung. Von der Rohrleitung e zweigen Leitungen el ab, die tangential in die   Staubsammler   f münden. Von der Gasleitung b führen Zweigrohre i2 zu einer zweiten Staubförderleitung e2. In diese Zweigrohre sind gleichfalls Absperrorgane   a2 und gtrahlpumpen C2   eingebaut, von welchen letztere an die   Staubsammler   angeschlossen sind. 



   Durch Öffnen der Hähne a strömt Fördergas in die Strahlpumpen e, reisst den durch die Hähne d aus   den Rohgasleitungen & zugeführten Staub   mit und führt ihn durch die Leitung e (Pfeil x, Fig. 2) und die Zweigleitungen el in die   Staubsammler   f. Zum Absaugen des Staubes aus den Staubsammlern, dessen

    Method and device for removing and forwarding gout dust
 EMI1.1
 



   The mode of operation of blast furnaces and similar shaft furnaces has the disadvantage that significant quantities of the feed are carried away with the gas flow in the form of dust, which is largely deposited again in the pipelines and dust collectors carrying the raw gas.



  The removal of this gas dust was previously known to be done by opening flap valves which are installed in the bottom of the dust collector and along the entire length below the raw gas lines. In this way, the dust from the dust collectors gets directly into open railroad tracks.

To explain the working process according to the invention, an embodiment of a device used for this purpose is shown in the drawing. Fig. 1 shows an elevation of such a system,
 EMI2.1
 Device.



   A pipe b is provided for supplying the furnace gas intended for conveying the blast furnace dust. The line b is connected by several connecting pipes i to a line e, which is intended for conveying the dust. A shut-off device a and a jet pump c are switched on in each connecting line i. The latter are connected to the raw gas lines h with the interposition of through cocks d. Lines el branch off from pipeline e and open tangentially into dust collector f. Branch pipes i2 lead from gas line b to a second dust conveying line e2. Shut-off devices a2 and jet pumps C2, of which the latter are connected to the dust collector, are also built into these branch pipes.



   By opening the taps a, the conveying gas flows into the jet pumps e, entrains the dust fed in through the taps d from the raw gas lines & and guides it through the line e (arrow x, Fig. 2) and the branch lines el into the dust collector f. For vacuuming the dust from the dust collectors, its

 cause the conveyor aisle, crushing or sieving devices can be provided between the dust collector f and jet pumps c2.



   PATENT CLAIMS:
