Description

Vorrichtung zum intensiven Begasen von Flüssigkeiten Die Erfindung betrifft eine Vorrichtung zum intensiven Begasen von Flüssigkeiten, wie sie etwa zur Förderung aerober biologischer Umsetzungen durch Mikroorganismen, zur Begünstigung des Hefewachstums usw eingesetzt werden.Device for intensive gassing of liquids The invention relates to a device for intensive gassing of liquids, such as to promote aerobic biological conversions by microorganisms, to promote of yeast growth, etc. can be used.

Vorrichtungen dieser Art sind bekannt. Sie weisen eine der Gaszuführung dienende Hohlwelle auf und eine mit dieser in gasleitender Verbindung stehende rotierende Hohlscheibe. Am Umfang der Hohlscheibe sind radial angeordnete Gasaustrittsöffnungen angebracht, über denen sich in geringem Abstand ein Abdeckblech befindet. Das Abdeckblech wird von einem Widerstandsblech getragen, welches in Strömungsrichtung gesehen vor den radialen Austrittsöffnungen befestigt ist. Auf diese Weise entsteht eine Wirbelkammer, die beim schnellen Rotieren der Hohlscheibe einen Sog erzeugt, der so groß ist, daß die Vorrichtung als selbstansaugende B egasungsvorrichtung arbeiten kann. Selbstverständlich ist es aber auch möglich, das der Flüssigkeit zuzuführende Gas, etwa Luft, bei der Vorrichtung nach der Erfindung unter Druck zuzuleiten. Devices of this type are known. You assign one of the gas supply lines serving hollow shaft and a rotating with this in gas-conducting connection Hollow disk. Radially arranged gas outlet openings are located on the circumference of the hollow disk attached, over which there is a cover plate at a short distance. The cover plate is carried by a resistance plate, which is seen in the direction of flow in front is attached to the radial outlet openings. In this way a vortex chamber is created, which, when the hollow disc rotates rapidly, generates suction that is so great that the device can work as a self-priming gas application device. Of course but it is also possible, the gas to be supplied to the liquid, such as air, in the To feed the device according to the invention under pressure.

Die Erfindung bezweckt, die Begasungswirkung dieser Vorrichtung weiter zu verbessern. Erfindungsgemäß wird daher vorgeschlagen, das Abdeckblech mit seinem freien, im Drehsinn hinter der Gas auch trittsöffnung liegenden Ende von der Hohlscheibenachse weg aufzubiegen, und zwar gegenüber der Hohlscheibentangente um einen Winkel von 30 bis 600. Auf diese Weise ergibt sich eine noch feinere Gasverteilung in der zu begasenden Flüssigkeit und demzufolge eine verbesserte Gas ausnutzung. The invention aims to further the gassing effect of this device to improve. According to the invention it is therefore proposed that the cover plate with his free end of the hollow disk axis, also located behind the gas opening, in the direction of rotation to bend away, namely opposite the concave tangent by an angle of 30 to 600. This results in an even finer gas distribution in the to fumigating liquid and consequently an improved gas utilization.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes vereinfacht dargestellt. The drawing shows an exemplary embodiment of the subject matter of the invention shown in simplified form.

F i g. 1 zeigt einen vertikalen Axialschnitt durch die Vorrichtung, Fig. 2 einen Ausschnitt aus Fig. 1 in größerem Maßstab, Fig. 3 einen Schnitt nach der Linie III-E in Fig. 2. F i g. 1 shows a vertical axial section through the device, FIG. 2 shows a detail from FIG. 1 on a larger scale, FIG. 3 shows a section according to FIG the line III-E in FIG. 2.

In einem Gefäß 1 ist eine Hohlwelle 2 mit einer Hohlscheibe 3 in einem Lager 4 drehbar gelagert. In a vessel 1 is a hollow shaft 2 with a hollow disk 3 in a bearing 4 rotatably mounted.

Am Umfapg der Hohlscheibe 3 sind radiale Gasaustrittsöffnungen 5 angebracht. Im Drehsinn vor den Gasaustrittsöffnungen 5 ist jeweils ein senkrecht auf dem Umfang der Hohlscheibe 3 stehendes Widerstandsblech 6 angeordnet. An diesem ist ein Abdeckblech 7 befestigt, das über die Gasaustrittsöffnung 5 hinwegreicht. Das Abdeckblech 7 ist mit seinem freien, im Drehsinn hinter der Gasaustrittsöffnung 5 liegenden Ende 8 von der Hohlscheibenachse weg um einen Winkel aufgebogen. Dieser Winkel beträgt beim Ausführungsbeispiel 400.Radial gas outlet openings 5 are attached to the circumference of the hollow disk 3. In the direction of rotation in front of the gas outlet openings 5 there is in each case a perpendicular to the circumference the hollow disk 3 standing resistance sheet 6 is arranged. There is a cover plate on this 7 attached, which extends beyond the gas outlet opening 5. The cover plate 7 is with its free, in the direction of rotation behind the gas outlet opening 5 lying end 8 bent up at an angle away from the hollow disk axis. This angle is in the embodiment 400.

Der Antrieb der Hohlscheibe 3 erfolgt über die mit ihr fest verbundene Hohlwelle 2 mittels eines nicht gezeichneten Motors. Der Antrieb der Hohlscheibe kann aber auch mittels einer von der Hohlwelle getrennten Welle, beispielsweise von unten her, erfolgen. The drive of the hollow disk 3 takes place via the firmly connected to it Hollow shaft 2 by means of a motor, not shown. The drive of the hollow disk but can also by means of a shaft separated from the hollow shaft, for example from below.
