KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die vorliegende. Erfindung bezieht sich auf solche Dampftrockner, Ueberhitzer oder Kondensatoren, deren gerade oder schlangenförmig gewundene, äufserlich beheizte oder gekühlte Rohre schraubenförmig gewundene Einlagen enthalten. Die bei diesen Vorrichtungen nach rechts oder nach links gewundenen, auf einander folgenden Einlagen werden entgegengesetzt gewunden; dadurch werden alle Theilchen des die Rohre durchströmenden Dampfes abwechselnd nach rechts und nach links gewendet und so wiederholt mit der Innenwand der beheizten oder gekühlten Rohre in Berührung gebracht.The present. Invention relates to such steam dryers, superheaters or condensers, their straight or serpentine coiled, externally heated or cooled tubes helically coiled inserts contain. Those wound to the right or to the left in these devices, on top of each other the following deposits are wound in the opposite direction; thereby all the particles of the the pipes flowing through the steam alternately turned to the right and to the left and so repeatedly in contact with the inner wall of the heated or cooled tubes brought.

Auf der Zeichnung ist als Beispiel ein Längsschnitt durch ein gerades Rohr dargestellt, das drei gemäfs dieser Erfindung angeordnete Einlagen enthält.In the drawing, a longitudinal section through a straight pipe is shown as an example contains three inserts arranged in accordance with this invention.

Von zwei auf einander folgenden Einlagen α b, welche von Blechstreifen gebildet sind, deren Breite dem inneren Durchmesser des Rohres c entspricht, ist die eine (a) links und die andere (b) rechts gewunden. Die Einlagen sind so in das Rohr c eingebracht, dafs ihre Endkanten an einander stofsen und senkrecht zu einander stehen. Um die richtige gegenseitige Stellung der Einlagen zu sichern, kann von zwei zusammenstofsenden Endkanten die eine mit einem Einschnitt d versehen werden, in welchen die andere Endkante eingreift.Of two successive inserts α b , which are formed by sheet metal strips, the width of which corresponds to the inner diameter of the tube c , one (a) is wound on the left and the other (b) on the right. The inlays are placed in the tube c in such a way that their end edges abut one another and are perpendicular to one another. In order to ensure the correct mutual position of the inserts, one of the two end edges that end together can be provided with an incision d into which the other end edge engages.

Beim Durchlaufen eines mit solchen Einlagen versehenen Rohres wird der Dampfstrom von der ersten Einlage α in zwei Ströme gespalten, welche, der Krümmung der Einlage folgend, nach links gewendet werden. Beim Verlassen der ersten Einlage treffen die beiden nach links gewendeten Dampfströme auf die senkrechte Endkante der nächsten Einlage und werden dadurch nach rechts gewendet u. s. f.When passing through a pipe provided with such inserts, the steam flow from the first insert α is split into two flows which, following the curvature of the insert, are turned to the left. When leaving the first insert, the two steam streams turned to the left meet the vertical end edge of the next insert and are thereby turned to the right and so on

Infolge dieser wechselnden Wendungen, welche der Dampf beim Durchströmen des beheizten oder gekühlten Rohres c durch die abwechselnd entgegengesetzt gewundenen Einlagen empfängt, wird er gewissermaafsen umgerührt und dadurch werden alle seine Theilchen wiederholt mit der heifsen oder gekühlten Innenwandung des Rohres c in Berührung gebracht, was zur Folge hat, dafs die Verdampfung des noch im Dampf enthaltenen Wassers, die Ueberhitzung trocknen Dampfes oder die Kondensation des Dampfes beschleunigt werden. In einem genügend langen, geraden oder schlangenförmig gewundenen, erhitzten Rohr c erzielt man sogar zunächst die Trocknung und dann die Ueberhitzung des das Rohr durchziehenden Dampfes.As a result of these alternating turns, which the steam receives as it flows through the heated or cooled tube c through the alternately oppositely wound inserts, it is to a certain extent stirred and thereby all its particles are repeatedly brought into contact with the hot or cooled inner wall of the tube c , which leads to The consequence is that the evaporation of the water still contained in the steam, the overheating of the dry steam, or the condensation of the steam are accelerated. In a sufficiently long, straight or serpentine wound, heated tube c , drying is first achieved and then overheating of the steam passing through the tube.
