Description

Anlage zum Mahlen, Fördern, Bunkern, Zuteilen und Verfeuern von Kohlenstaub Es sind Kohlenstaubaufbereitungsanlagen hekannt, bei welchen die Kohle in einem zusammenhängenden Arbeitsgang gemahlen, gefördert und gebunkert oder verfeuert wird. Die Förderleitungen solcher Anlagen hat man derart ausgebildet, daß, sich zwischen Mühle und Brenner die Färderleitung in zwei parallele Stränge teilt, in deren einen ein Staubabscheider mit Bunker und Zuteilvorrichtung .eingeschaltet ist und durch deren zweiten Strang die Staubluft direkt zum Brenner fließt.Plant for grinding, conveying, bunkering, distributing and burning coal dust There are coal dust processing plants known in which the coal in one coherent operation is ground, conveyed and bunkered or burned. The delivery lines of such systems have been designed so that between Mill and burner divides the conveyor line into two parallel strands, one of which a dust separator with bunker and metering device is switched on and through the second line of which the dust air flows directly to the burner.

Erfindungsgemäß wird dieser zweite Strang, die Umgehungsleitung des Bunkers, durch ein Regelorgan absperrbar gemacht und der Ventilator, der als gemeinsamer Mühlen- und Einblaseventilator arbeitet, in. denjenigen Teil der Rohrleitung @eingeschaltet, welcher bei abgesperrtem Regelorgan der Umgehungsleitung nur von entstaubter Luft durchströmt wird. Man setzt dadurch den Ventilatorverschleiß herab und hält den Staubabscheider unter Unterdruck. Damit in allen Fällen der Ventilator genügend Verbrennungsluft fördert, ist auf der Saugseite noch ein regelbarer Lufteinlaß vorgesehen.According to the invention, this second strand, the bypass line of the Bunkers, made lockable by a regulating device and the fan, which is used as a common Mill and injection fan works, in that part of the pipeline @ is switched on, which when the control element of the bypass line is shut off only from dust-free air is flowed through. This reduces the fan wear and keeps the Dust separator under negative pressure. So in all cases the fan is sufficient Promotes combustion air, an adjustable air inlet is provided on the suction side.

In der Zeichnung ist die Anordnung schematisch dargestellt. Der in der Mühle a erzeugte Staub wird von der Förderluft durch die Rohrleitungen c, h und e zum Ventilator b getragen, der ihn durch die Leitung f zum Brenner g drückt. Schließt man die Klappe in der Leitung fz, so tritt die Luft aus c in den Staubabscheider d, dessen unterer Teil i als Staubbunker ausgebildet ist. Die entstaubte Abluft geht durch Leitung e zum Ventilator b und weiter durch Leitung f, in welche mit Hilfe der Aufgabevorrichtung h in von der Erzeugung unabhängiger, regelbarer Weise Staub aus dem Bunker! aufgegeben wird, zum Brenner g. Um die Förderluftmenge von der zur Verbrennung benötigten Luftmenge unabhängig zu machen, ist auf der Saugseite des Ventilators ein regelbarer Lufteinlaß, vorgesehen. Dieser Lufteinlaß gestattet die Förderung der Verbrennungsluft auch dann., wenn die Mühle außer Betrieb, ist und die Leitungen c und e abgeschlossen smd. Die Anordnung bietet daher auch die Möglichkeit, ohne Mühle vom Bunker allein zu arbeiten.The arrangement is shown schematically in the drawing. The dust generated in the mill a is carried by the conveying air through the pipes c, h and e to the fan b, which pushes it through the line f to the burner g. If the flap in the line fz is closed, the air from c enters the dust separator d, the lower part i of which is designed as a dust bunker. The dedusted exhaust air goes through line e to fan b and further through line f, into which, with the help of the feed device h, dust from the bunker can be regulated independently of the generation! is abandoned, to the burner g. In order to make the amount of conveying air independent of the amount of air required for combustion, a controllable air inlet is provided on the suction side of the fan. This air inlet allows the combustion air to be conveyed even when the mill is out of operation and lines c and e are closed off. The arrangement therefore also offers the possibility of working alone from the bunker without a mill.
