Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Der vorliegende Gegenstand bezweckt eine beschleunigte Circulation der abzudampfenden Flüssigkeit in den Heizrohren von Verdampfern, einen vermehrten Wärmeaustausch an den Wandungen dieser Röhren und eine schnellere Abdampfung der einzudickenden Flüssigkeit. Dieser Zweck wird mit Hülfe von Ueberhöhungsrohrstücken, welche mit in den Heizröhren angebracht sind, erreicht.The purpose of the present object is to accelerate the circulation of the steam to be evaporated Liquid in the heating tubes of evaporators, an increased heat exchange to the Walls of these tubes and a faster evaporation of the liquid to be thickened. This purpose is achieved with the help of cant pipe pieces, which are included in the heating tubes are appropriate, achieved.

Fig. ι zeigt den gewöhnlichen Robert'schen Verdampfer undFig. Ι shows the usual Robert's Evaporator and

Fig. 2 denselben Apparat mit der vorliegenden Neuerung.2 shows the same apparatus with the present innovation.

Bei dem gewöhnlichen Robert'schen Apparat lastet die oberhalb B befindliche Flüssigkeitsschicht auf dem Inhalt der Heizrohre r und hemmt deren Bewegung. Sperrt man aber die oberhalb B befindliche Flüssigkeit von der in den Rohren r aufsteigenden ab, so wird die directe Belastung von der aufsteigenden Schicht in r genommen ■ und diese Flüssigkeit kann ungehemmt und lebhaft austreten. Diese Absperrung geschieht mit Ueberhöhungsrohrenden s, Fig. 2. Es entsteht infolge dieser Absperrung eine lebhafte Circulation in den Rohren r, ein freies Ausschäumen aus den Rohrenden s und somit eine sehr intensive Abdampfung.In the usual Robert apparatus, the layer of liquid above B rests on the contents of the heating tubes r and inhibits their movement. If, however, the liquid above B is shut off from the liquid rising in the pipes r, the direct load from the rising layer in r is taken and this liquid can escape unchecked and vigorously. This shut-off is done with elevation pipe ends s, Fig. 2. As a result of this shut-off, a lively circulation arises in the pipes r, a free foaming from the pipe ends s and thus a very intensive evaporation.

Dieses Resultat wird deshalb erreicht, weil die volle, d. h. schaumfreie Flüssigkeit, welche im Circulationsrohr C herabsinkt, die durch Dampfentwickelung schaumdurchsetzte, d. h.This result is achieved because the full, i.e. H. foam-free liquid, which in the circulation pipe C sinks, the foam permeated by the development of steam, d. H.

leichtere Flüssigkeit in den Rohren r in die Höhe drückt. Das in den Rohren r aufsteigende Gemenge von Flüssigkeit und Dampf kann ungehindert und deshalb lebhaft austreten. Es giebt hierbei die mitgeführten Dampfblasen frei. Die dampflose Flüssigkeit fällt auf das normale Niveau zurück und wiederholt ihren Lauf durch C nach unten.pushes up lighter liquid in the tubes r. The one rising in the tubes r Mixtures of liquid and vapor can escape unhindered and therefore briskly. It releases the entrained vapor bubbles. The vapor-free liquid is noticeable returns to normal level and repeats its run down through C.

Es ist also bei diesem mit den Rohrenden s armirten Apparat die obere Communication der sinkenden, in C, und der ansteigenden Flüssigkeit, in r r r r . . ., gesperrt. Die Differenz der Schwere der herabsinkenden, blasenlosen, und der aufsteigenden, blasenreichen Flüssigkeitssäulen wird in ihrem ganzen Umfang ausgenutzt, um die Circulation der abzudampfenden Flüssigkeit zu beschleunigen und den Wärmeaustausch an den Wandungen der Heizrohre zu vermehren. It is thus in this with the pipe ends s armirten apparatus, the upper Communication of falling, in C, and the rising liquid in rrrr. . ., locked. The difference in gravity of the descending, bubble-free, and the ascending, bubble-rich columns of liquid is used to its full extent to accelerate the circulation of the liquid to be evaporated and to increase the heat exchange on the walls of the heating pipes.

Das Verhältnifs der Schwere der Flüssigkeitssäulen in C und r ist durch die Verschiedenheit der Schraffur in Fig. 2 angedeutet.The ratio of the gravity of the liquid columns in C and r is indicated by the difference in hatching in FIG.
