Description

Vorrichtung zur feinen Verteilung von Gasen in Flüssigkeiten Zur feinen Verteilung von Gasen in Flüssigkeiten verwendete man bisher meistens Filterplatten oder -kerzen, welche aber für den praktischen Betrieb wenig geeignet sind, da die feinen Poren der Filtermaterialien sich leicht verstopfen und dadurch zu unliebsamen Betriebsunterbrechungen führen. Man hat auch schon Vorrichtungen vorgesdilagen, die aus wellenförmig gestalteten Platten oder konzentrisch angeordneten Rohrstücken bestehen und so nebeneinander- bzw. ineinandergelegt sind, daß wellenförmige Kanäle gebildet werden, durch welche die zu mischenden Stoffe hindurchgeführt und zufolge der Prallwirkung an den Umlenkstelkn innig miteinander gemischt werden.Device for fine distribution of gases in liquids for fine For the distribution of gases in liquids, filter plates have mostly been used up to now or candles, which are not very suitable for practical use, as the The fine pores of the filter materials can easily become clogged and become unpleasant Cause business interruptions. Devices have already been prepared those made of wave-shaped plates or concentrically arranged pieces of pipe exist and are so juxtaposed or nested that wave-shaped channels are formed, through which the substances to be mixed passed and according to the impact at the deflection knuckles are intimately mixed with one another.

Gemäß vorliegender Erfindung wird die feine Verteilung von Gasen in Flüssigkeiten mit einer Vorrichtung erzielt, in welcher gegenüber den Mündungen der beiden konzentrisch angeordneten Rohre sich in geringem Abstand und quer zur Strömungsrichtung Teller befinden, so daß schlitzartige Austrittsöfinungen entstehen. Gegenüber der bekannten obenerzvähnten Einrichtung weist diese Ausführung bei ungefähr gleicher Mischwirkung einen wesentlich einfacheren Aufbau auf. According to the present invention, the fine distribution of gases achieved in liquids with a device in which opposite the mouths of the two concentrically arranged tubes are at a small distance and transversely to Direction of flow plate are located, so that slot-like outlet openings arise. Compared to the known device mentioned above, this version has approximately the same mixing effect on a much simpler structure.

Einige Ausführungsbeispiele zeigen die Abb. I bis 3 in der beiliegenden Zeidinung. Some embodiments are shown in Figs. I to 3 in the enclosed Zeidinung.

Die Gas-T;lüssigkeits-Mischung wird hier dadurch erzielt, daß das Gaszuführungsrohr I innerhalb des Flüssigkeitszuführunbsrohres z verlegt und seine Mündung durch einen Prallteller 3 derartig abgeschirmt ist, daß das Gas tellerförmig in feiner Schicht senkrecht zur Flüssigkeitsströmung ausgebreitet und von der aufprallenden Flüssigkeit daher leicht zerteilt wird. Der zum Auseinanderreißen der so gebildeten größeren Blasen erforderliche Austrittsschlitz wird bei Abb. I und 2 durch den vor der Mündung des äußeren Rohres 2 angebrachten Teller 4 erzielt, bei Abb. 3 durch den nach oben gebogenen Rand 4 des Tellers 3. Bei Abb. 2 ist außerdem zur besseren Durchmischung eine Umlenkung nach unten durch Rohr 5 vorgesehen. Die Düse nach Abb. 3 kann auch mit trichterförmiger Mündungserweiterung von Rohr 2 aus gebildet und der Rand 4 auch fortgelassen werden. The gas-liquid mixture is achieved here in that the Gas supply pipe I laid within the liquid supply pipe z and his Muzzle is shielded by a baffle plate 3 in such a way that the gas is plate-shaped Spread out in a fine layer perpendicular to the flow of liquid and away from the impinging one Liquid is therefore easily broken up. The one to tear apart those so educated The exit slit required for larger bubbles is shown in Fig. I and 2 through the front the mouth of the outer tube 2 attached plate 4 achieved, in Fig. 3 by the upwardly bent edge 4 of the plate 3. In Fig. 2 is also for the better Mixing, a downward deflection through tube 5 is provided. The nozzle according to Fig. 3 can also be formed with a funnel-shaped mouth widening from tube 2 and the edge 4 can also be omitted.
