Description
Verfahren zum Belüften. von Flüssigkeiten durch Gase Im Patent 594 671 ist ein Verfahren. zur Feinstbelüftung von Diaphragmen-Gäxbottichenbeschrieben, derenLuftverteiler aus Platten, welche aus Diaphragmenmasse hergestellt sind, bestehen. Es wurde nun gefunden, daß bei Anwendung feinporöser Kerzen die Belüftungsdichte bei einer Wirbelung der Gas-oder Luftbläschen steigt, was dadurch zu :erklären ist, daß die von den Bläschen in der Zeiteinheit bestrichene Oberfläche bzw. der von ihnen zurückgelegte Weg sich vergrößert.Method of ventilation. of liquids from gases in Patent 594 671 is a method. for the fine ventilation of diaphragm gas tubs, the air distributors of which consist of plates made of diaphragm mass. It has now been found that when fine-pored candles are used, the ventilation density increases when the gas or air bubbles are swirled, which can be explained by the fact that the surface covered by the bubbles in the unit of time or the distance covered by them increases.
Dieser Effekt hat mit der bekannten Vorrichtung der Mischdüsen und Rührwerke insofern. nichts zu tun, als ier hier lediglich durch eine besondere Anordnung der Belüftungskörper hervorgerufen wird.This effect has with the known device of the mixing nozzles and Agitators insofar. nothing to be done here except simply by a special arrangement the ventilation body is caused.
Das-in der beiliegenden Zeichnung in verschiedenen Abbildungen dargestellte Belüftungssystem trägt nun diesen Umständen Rechnung. In den Abb. i, 2, 3 und 4 ist das neue Belüftungssystem dargestellt: d ist das Hauptluftrohr, b1 bis b. sind Abzweigrohre. In diese Abzweigrohre sind in bestimmten Abständen Belüftungskerzen aus feinporösen Diaphragmenmassen, cl bis c, in einem für jede Kerze beliebigen Winkel eingeschraubt. Dadurch steht über jeder Kerze ein je nach der Winkelstellung verschiedener Flüssigkeitsdruck, bei der Belüftung wird also aus diesem Grunde beispielsweise aus der Kerze cl mehr Luft heraustreten als aus der Kerze c2, wenn der Unterschied des. Winkels- auch nur 2° beträgt: Die Kerzen in Abb. i stehen für eine Kerzenreihe in gleicher Winkelstellung, in den folgenden Reihen verändert sich spiralisch zur Achse die Winkelstellung, was in der Abb. 2 durch verschiedene Länge der Kerzen dargestellt ist. Auch kann man die Wirkung der verschiedenen Winkelstellung noch dadurch- erhöhen, daß man die Kerzen in verschiedener Länge, wie Abb. 3 zeigt, ausführt. Auf diese Weise erhält man über dem Belüftungssystem eine lebhafte Wirbelbildung. Um die Bewegung der Gesamtflüssigkeit zu erhöhen, kann man, wie ies Abb. 4 zeigt, die Belüftungsdichte feldermäßig dadurch abstufen, .daß man beispielsweise die Kerzen des Feldes x1 nach der Richtung x2 wachsen läßt, ,entsprechend die Kerzen des Feldes x2 nach x3 usw. Hierdurch wird noch seine Strömungsbewegung der ganzen Flüssigkeit innerhalb des Bottichs terzeugt, die ebenfalls dazu dient, den Effekt der Durchlüftung zu erhöhen.That-shown in the accompanying drawing in different images Ventilation system now takes these circumstances into account. In Figs. I, 2, 3 and 4 the new ventilation system is shown: d is the main air pipe, b1 to b. are Branch pipes. In these branch pipes there are ventilation candles at certain intervals from fine-pore diaphragm masses, cl to c, in any one for each candle Screwed in angle. As a result, there is a depending on the angular position above each candle different fluid pressures, for this reason, for example, during ventilation more air will come out of the candle cl than out of the candle c2 if the difference is des. Angle is also only 2 °: The candles in Fig. i stand for a row of candles in the same angular position, in the following rows changes spirally to Axis the angular position, which is shown in Fig. 2 by different lengths of the candles is shown. You can also still see the effect of the different angular positions by making the candles in different lengths, as shown in Fig. 3. In this way a lively vortex formation is obtained above the ventilation system. In order to increase the movement of the total liquid, one can, as Fig. 4 shows, Graduating the ventilation density by field by, for example, using the candles of the field x1 can grow in the direction x2, corresponding to the candles of the field x2 to x3 and so on. Hereby its flow motion of the whole liquid becomes inside the tub, which also serves to create the effect of ventilation to increase.
