von Trockenzylinflern.of dry-cylinder fliers.
Gegenstand vorliegender Erfindung ist ein Verfahren zur Erzielung einer hohen Wärmeabgabe des Heizdampfes an die Mäntel von Trockenzylindern.The present invention is a method for achieving a high heat output of the heating steam to the jackets of drying cylinders.
Die Anwendung des Dampfkreislaufes in Dampfheizkörpern ist bereits bekannt. Gemäß der vorliegenden Erfindung soll, um in den Heizräumen von Trockenzylindern die Wärmeabgabe durch den Mantel zu erhöhen undThe application of the steam cycle in steam radiators is already known. According to The present invention is intended to reduce the heat output in the boiler rooms of drying cylinders by raising the coat and
ίο dadurch mit geringeren Dampfspannungen größere Trockenleistungen zu erzielen, ein beschleunigter Umlauf des eingeführten Dampfes und infolgedessen ein gesteigerter Wärmeaustausch zwischen dem wärmezuführenden Mittel und dem wärmeabgebenden Mantel herbeigeführt werden.ίο thus with lower steam tensions To achieve greater drying capacities, an accelerated circulation of the imported Steam and, as a result, an increased heat exchange between the heat-supplying Means and the heat-emitting jacket are brought about.
Das neue Verfahren besteht darin, daß der Frischdampf in den Trockenzylinder durch eine Düse eingeblasen wird, wobei dann die während des Einblasens von der Düse ausgeübte Saugwirkung dazu dient, den bereits in dem Zylinder befindlichen Dampf von neuem nach der Düse hin anzusaugen und wiederholt in Umlauf zu bringen, wie dies bei Dampfheizkörpern üblich und bekannt ist. Zur Erläuterung der Ausübung dieses Verfahrens wird auf der Zeichnung ein Trockenzylinder dargestellt, an welchem die besondere Wirkung der Düse leicht ersichtlich ist.The new procedure is that the Live steam is blown into the drying cylinder through a nozzle, in which case the The suction effect exerted by the nozzle during the injection serves to remove the already to suck in steam in the cylinder again towards the nozzle and to be brought into circulation repeatedly, as is customary and known for steam radiators. To explain the practice of this process, a drying cylinder is shown in the drawing shown, on which the special effect of the nozzle can be easily seen.
Wie die Ausführungsform zeigt, sind die Böden b des Zylinders α tief eingezogen und lassen zwischen sich und dem Trockenzylindermantel nur schmale Ringspalten c frei. Nahe den äußeren Enden des Zylinders führen Verbindungsrohre d aus dem Ringspalt in den hohlen Zapfen e als Saugraum der Düse.As the embodiment shows, the bottoms b of the cylinder α are drawn in deeply and leave only narrow annular gaps c free between them and the drying cylinder jacket. Near the outer ends of the cylinder, connecting pipes d lead out of the annular gap into the hollow pin e as the suction chamber of the nozzle.
Der frische Dampf wird dann durch die Düse f in den mittleren Raum g des Zylinders zwischen den beiden Böden b eingeblasen. Von hier aus steigt der Frischdampf mit dem wieder angesogenen nach dem Ringraum am Mantel auf, durchströmt denselben bis zum Ende und tritt von hier aus durch die Verbindungsrohre d wieder in das Saugrohr e ein, worauf der Kreislauf von neuem beginnt.The fresh steam is then blown through the nozzle f into the central space g of the cylinder between the two floors b. From here the live steam rises with the again sucked in after the annular space on the jacket, flows through the same to the end and from here enters the suction pipe e again through the connecting pipes d , whereupon the cycle begins again.
Die Abführung des Niederschlagwassers aus den Zylindern erfolgt durch den der Dampfeinströmung gegenüberliegenden Zapfen in der bekannten Weise durch Schöpfer oder durch Einhängerohre.The drainage of the rainwater from the cylinders takes place through the Steam inflow opposite spigot in the known manner by scoop or through hanging tubes.
Bei diesem Verfahren findet infolge der hohen Geschwindigkeit, mit welcher der Dampf an der zu beheizenden Fläche entlang streicht, ein vorzüglicher Wärmeaustausch statt.In this process, due to the high speed at which the Steam brushes along the surface to be heated, an excellent heat exchange instead of.
