Description
Vorrichtung zum Belüften von Abwässern Die Erfindung betrifft eine Vorrichtung zum Belüften von Abwässern, die aus einem Bottich mit einem in der Mittelachse des Bottichs angeordneten Rotorsystem besteht, dessen hohle Welle mit den Rotorarmen in luftdurchlässiger Verbindung steht und in einem Fallrohr angeordnet ist. Es sind bereits Vorrichturgen zum Belüften von Abwasser bekannt, bei denen die Luft aus Bohrungen eines im Wasser rotierenden Zylinders austritt, und zwar unmittelbar hinter nasenförmigen Ausformungen des Zylinders.Apparatus for aerating waste water The invention relates to a Device for aerating waste water coming from a vat with one in the central axis of the tub arranged rotor system, whose hollow shaft with the rotor arms is in air-permeable connection and is arranged in a downpipe. There are Vorrichturgen already known for the ventilation of wastewater, in which the air from Bores of a cylinder rotating in the water emerges, directly behind nose-shaped formations of the cylinder.
Bei der Rotation des Zylinders entsteht hinter diesen Ausformungen ein gewisses Vakuum, so daß der Austritt des Gases in die Flüssigkeit erleichtert wird. Der Nachteil dieser bekannten Vorrichtungen besteht darin, daß die Luft in unmittelbarer Nähe des Zylinders bleibt und von dort nach oben steigt, so daß eine innige Mischung mit der Flüssigkeit nicht erfolgen kann. Außerdem ist es auch bekannt, auf eine hohle Rotorwelle hohle Scheiben aufzusetzen, in die die Luft aus der Rotorwelle eintritt und aus denen sie ebenfalls hinter nasenförmigen Ausformungen austritt. When the cylinder rotates, formations are created behind these a certain vacuum, so that the escape of the gas into the liquid facilitates will. The disadvantage of these known devices is that the air in remains in the immediate vicinity of the cylinder and rises from there upwards, so that a intimate mixing with the liquid cannot take place. Besides, it is also known Put on a hollow rotor shaft hollow disks into which the air from the rotor shaft enters and from which it also exits behind nose-shaped formations.
Auch hier kann keine innige Vermischung von Flüssigkeit und Luft erzielt werden, da die Wirkung praktisch ebenso ist wie bei den vorbeschriebenen Zylindern. Zwar kann der Sauerstoffeintrag durch Anwendung einer Mehrzahl von Scheiben verbessert werden, jedoch wird die Vorrichtung dann sehr aufwendig, ohne daß ein Optimum an Wirkung erreicht wird. Here, too, there can be no intimate mixing of liquid and air can be achieved because the effect is practically the same as the above Cylinders. It is true that the introduction of oxygen can be achieved by using a plurality of disks be improved, but the device is then very expensive without a Optimum effect is achieved.
Aufgabe der Erfindung ist es, die aufgezeigten Nachteile zu beseitigen und durch die besondere Ausbildung der Rotorarme eine optimale Vermischung von Flüssigkeit und Sauerstoff zu erreichen, um gleichzeitig eine Mischzone gewollter Größe herzustellen. The object of the invention is to eliminate the disadvantages indicated and due to the special design of the rotor arms, an optimal mixing of the liquid and oxygen to simultaneously create a mixing zone of the desired size.
Diese Aufgabe wird bei einer Vorrichtung zum Belüften von Abwässern, die aus einem Bottich mit einem in der Mittelachse des Bottichs angeordneten Rotorsystem, dessen hohle Welle mit den Rotorarmen luftdurchlässig verbunden ist, besteht, dadurch gelöst, daß die Rotorarme in an sich bekannter Weise einen tropfenförmigen Querschnitt aufweisen und die äußeren Enden der Rotorarme mit Wirbel erzeugenden flachen Störkörpern besetzt sind und daß über den Rotorarmen ein konischer Ablenkteller und unter dem Rotor ein Statorstumpf angeordnet sind. This task is performed with a device for aerating waste water, consisting of a tub with a rotor system arranged in the central axis of the tub, whose hollow shaft is connected to the rotor arms in an air-permeable manner, consists thereby solved that the rotor arms in a known manner a teardrop-shaped cross-section have and the outer ends of the rotor arms with vortex-generating flat disruptive bodies are occupied and that a conical deflector plate and below the rotor arms Rotor are arranged a stator stump.
Das Fallrohr, in dem die Welle angeordnet ist, und der in seinem untersten Ende angeordnete Ablenkteller bestehen entweder aus einem Stück oder der Ablenkteller ist unmittelbar am Fallrohr befestigt. The downpipe in which the shaft is located and the one in his Lower end arranged deflection plates consist either of one piece or the The deflector plate is attached directly to the downpipe.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigt F i g. 1 einen Schnitt durch die Vorrichtung, F i g. 2 den Rotor mit den Rotorarmen, Fig. 3 einen Querschnitt durch einen Rotorarm. An exemplary embodiment of the invention is shown in the drawing. It shows F i g. 1 shows a section through the device, FIG. 2 the rotor with the Rotor arms, FIG. 3 shows a cross section through a rotor arm.
Auf dem Bottich 1 liegt eine Traverse 2, die den Antriebsmotor 8 trägt. Von diesem wird die hohle Welle 7 angetrieben, die das Fallrohr 6 durchsetzt. A crossbeam 2, which drives the drive motor 8, lies on the tub 1 wearing. The hollow shaft 7, which passes through the downpipe 6, is driven by this.
Das Fallrohr 6 endet oben in einer trichterförmigen Öffnung 5 und am unteren Ende in einem kegeligen Ablenkteller 11. Unterhalb dieses Ablenktellers 11 sitzt auf der Welle 7 der Rotor 9. Dieser Rotor 9 besteht im einzelnen aus der Muffe 14, in der die eigentlichen Rotorarme 12 befestigt sind. Wie die Fig. 3 zeigt, besitzen die Rotorarme 12 tropfenförmigen Querschnitt. Auf ihrem äußeren Ende sind Wirbel erzeugende flache Störkörper 13 befestigt, hinter denen die Luft aus den hohlen Rotorarmen 12 austritt. Zu dem Fallrohr 6 führt von der Seite her eine Leitung 3, und unten führt aus dem Bottich eine Abflußleitung 4 heraus. Die Wirkungsweise der Vorrichtung ist folgende: Das aufzubereitende Abwasser fließt durch die Leitung 3 und fällt durch das Fallrohr 6 nach unten.The downpipe 6 ends at the top in a funnel-shaped opening 5 and at the lower end in a conical deflection plate 11. Below this deflection plate 11 sits on the shaft 7 of the rotor 9. This rotor 9 consists in detail of the Sleeve 14 in which the actual rotor arms 12 are attached. As Fig. 3 shows, the rotor arms 12 have teardrop-shaped cross-section. Are on their outer end Vortex-generating flat disruptive bodies 13 attached, behind which the air from the hollow rotor arms 12 exits. A line leads to the downpipe 6 from the side 3, and at the bottom a drain line 4 leads out of the tub. The mode of action of the device is as follows: The wastewater to be treated flows through the pipe 3 and falls down through the downpipe 6.
Der Fall wird durch den am Boden B des Bottichs 1 angeordneten Statorstumpf 10 abgebremst, so daß das Abwasser nach allen Seiten strömt. In dieser Zone dreht sich der Rotor 9, wobei die Rotorarme 12 auf Grund ihrer Tropfenform mit nur geringem Widerstand in der Flüssigkeit umlaufen. Die Störkörper 13 dagegen bedingen bei der Bewegung durch die Flüssigkeit eine Strahlablösung und erzeugen damit eine starke Wirbelbildung in der Gegend ihrer Umlaufbahn. Da in dieser Umlaufbahn die Luft aus den hohlen Rotorarmen austritt, gelangt sie unmittelbar in die von starken Wirbeln erfüllte Zone, so daß eine innige Durchmischung des Abwassers mit Sauerstoff eintritt, die durch die Lenkung derFlüssig- keitsströmung durch den Ablenkteller 11 und den Stator 10 in einer örtlich begrenzten Turbulenzzone begünstigt wird.The fall is caused by the stator stump arranged on the bottom B of the tub 1 10 braked so that the sewage flows in all directions. Rotates in this zone the rotor 9, the rotor arms 12 due to their teardrop shape with only a slight Resistance circulate in the liquid. The disruptive bodies 13, on the other hand, require the Movement through the liquid creates a jet separation and thus a strong one Vortex formation in the area of their orbit. Because in this orbit the air is out Exiting the hollow rotor arms, it goes directly into those of strong eddies filled zone, so that an intimate mixing of the wastewater with oxygen occurs, which by directing the liquid flow through the deflection plate 11 and the stator 10 is favored in a localized turbulence zone.
Durch die Ausbildung der Vorrichtung nach der Erfindung wird gegenüber den bekannten Vorrichtungen eine wesentlich gesteigerte Sauerstoffaufnahme erreicht. The design of the device according to the invention is opposite the known devices achieved a significantly increased oxygen uptake.
