Titel: Vorrichtung zum Belüften bzw. Begasen von Flüssigkeiten Title: Device for aerating or gassing liquids
Die Erfindung bezieht sich auf eine Vorrichtung zum Belüften bzw. Begasen von Flüssigkeiten, insbesondere zum Einmischen von Luft bzw· Rauchgasen in freie Gewässer oder in in Großbehältern befindliches Wasser, mit einer in die Flüssigkeit eingetauchten, etwa lotrechten Antriebswelle, an deren unterem Ende ein Mischrad mit im wesentlichen radialen Schaufeln befestigt ist, wobei eine in Uähe der Radnabe mündende, zur Antriebswelle koaxiale Luft- bzw. Gras-Zufuhrleitung vorgesehen ist.The invention relates to a device for aerating or gassing liquids, in particular for mixing in Air or flue gases in open waters or in water in large containers, with an immersed in the liquid, approximately vertical drive shaft, at the lower end of which a mixing wheel with essentially radial blades is attached, wherein an air or grass supply line which opens near the wheel hub and is coaxial with the drive shaft is provided.
Zur Reinigung von Abwässern und ähnlichen Flüssigkeiten werden häufig chemische Reaktionen und/oder biologische Prozesse durchgeführt, die es erforderlich machen, den Abwässern bzw. Flüssigkeiten Sauerstoff, Luft oder ein anderes Gras, insbesondere Rauchgas, zuzuführen.Chemical reactions and / or biological processes are often carried out to purify wastewater and similar liquids, which make it necessary to the sewage or liquids oxygen, air or another grass, in particular Flue gas to be supplied.

Für eine solche Belüftung bzw. Begasung von Abwässern und ähnlichen Flüssigkeiten sind bereits zahlreiche Vorrichtungen bekanntgeworden; insoweit wird lediglich beispielehalber auf die DT-PSen 505 793^und 920 844, M-AS 1 782 485, OE-PS 220 092 sowie IR-PSen 1 092 827 und 1 238 593 verwiesen. Diesen bekannten Vorrichtungen haftet jedoch sämtlich der Nachteil an, daß die Ausnutzung des Sauerstoff-, Luft- oder Gaseintrage schlecht und/ oder der Energie-Wirkungsgrad ungenügend und/oder die konstruktive Ausgestaltung zu aufwendig ist.Numerous devices have already become known for such aeration or fumigation of waste water and similar liquids; in this respect, reference is only made to the DT-PSs 505 793 ^ and 920 844, M-AS 1 782 485, OE-PS 220 092 and IR-PSs 1 092 827 and 1 238 593 referenced. This well-known Devices, however, all have the disadvantage that the use of oxygen, air or gas input is poor and / or the energy efficiency is insufficient and / or the structural design is too complex.
Hier will die Erfindung Abhilfe, d.h. also eine Vorrichtung zur Belüftung bzw. Begasung von Flüssigkeiten schaffen, die die vorerwähnten Nachteile vermeidet sowie darüber hinaus innerhalb eines weiten Anwendungsbereichs einsatzfähig ist und auch größere Abwasser- bzw. Flüssigkeitsmengen gleichmäßig belüftet bzw. begast. Ausgehend von einer Vorrichtung der eingangs beschriebenen Art wird diese Aufgabe erfindungsgemäß dadurch gelöst, daß das Mischrad nach Art eines Pumpenlaufrads ausgebildet ist und aas einer auf der Ober- und Unterseite mit Schaufeln bestückten Scheibe besteht.The invention aims to remedy this, i.e. a device for Create aeration or gassing of liquids, which avoids the disadvantages mentioned above and can also be used within a wide range of applications, including larger ones Wastewater or liquid quantities evenly aerated or gassed. Based on a device of the type described at the outset This object is achieved according to the invention in that the mixing wheel is designed in the manner of a pump impeller and aas consists of a disc equipped with blades on the top and bottom.
Aufgrund dieser baulich sehr einfachen Ausgestaltung saugt das Miβehrad über geeignete Vorsehaltvorrichtungen von oben Sauerstoff, Luft oder Gas und von unten Abwasser an und bringt diese Medien beim radialen Ausstoß zur innigen Vermischung und damit zu einem hohen Grad an Reaktion. Außerdem hat sich gezeigt, daß der angesaugte Sauerstoff die angesaugte Luft bzw. das angeeaug-Due to this structurally very simple design, the bicycle sucks in oxygen, air or gas from above and brings it in from below via suitable holding devices Media with radial ejection for intimate mixing and thus for a high degree of reaction. It has also been shown that the sucked in oxygen the sucked in air or the sucked in

te Gras sehr feinblasig mit dem Abwasser bzw. der Flüssigkeit vermischt wird, so daß der jeweilige Eintrag von dem Abwasser bzw. der Flüssigkeit weitgehend aufgenommen wird. Schließlich bietet die beim Einsatz der erfindungsgemäßen Vorrichtung beobachtete Schaumbildung die Möglichkeit, in dem Abwasser bzw. der Flüssigkeit enthaltene Schmutzpartikel herauszuflotieren.The grass is very fine-bubbled mixed with the waste water or the liquid is so that the respective entry is largely absorbed by the wastewater or the liquid. Finally offers the foam formation observed when using the device according to the invention, the possibility in the waste water or the liquid to float out any dirt particles it contains.
Sas jeweils erforderliche Mischrad wird nach dem im Kreiselpumpenbau für das Pumpenlaufrad üblichen Berechnungsverfahren berechnet und auch nach den dort geltenden Konstruktionsrichtlinien konstruiert. Sind die anzusaugende Luft- bzw. Grasmenge, die umzuwälzende Wassermenge und die Drehzahl des Mischrads bekannt, werden die Gfeschwindigkeitsdreiecke berechnet, womit die Ein- und Austrittswinkel der radialen Schaufeln festliegen.The mixing wheel required in each case is based on the one in centrifugal pump construction Calculated for the usual calculation method for the pump impeller and also according to the design guidelines applicable there constructed. If the amount of air or grass to be sucked in, the amount of water to be circulated and the speed of the mixing wheel are known, the velocity triangles are calculated, with which the entry and exit angles of the radial blades are fixed.
Berechnungsgrundlage für die Ein- und Austrittswinkel der Schaufeln ist die FörderhöhengleiehungCalculation basis for the inlet and outlet angles of the blades is the funding height equation

sind. Sie Schaufeln werden so aufgezeichnet) daß der Eintrittswinkel P^ und der Austrittswinkel P^ auf einem Kreisbogen mit dem Radius r liegen, was die Herstellung der Mischräder wesentlich vereinfacht.are. The blades are recorded in such a way that the entry angle P ^ and the exit angle P ^ lie on an arc with the radius r, which considerably simplifies the manufacture of the mixing wheels.
In weiterer Ausgestaltung der Erfindung beträgt der Austrittswinkel /3 2 der Schaufeln etwa 90°. Ein derartiges Mischrad entspricht annähernd einem bei iurbo-Vakuum-Pumpen verwendeten laufrad, das aufgrund dee Austrittswinkelsβ 2 von etwa 90° praktisch nur G-eschwindigkeitsenergie erzeugt, die wiederum die Gasansaugung bewirkt.In a further embodiment of the invention, the exit angle / 3 2 of the blades is approximately 90 °. Such a mixing wheel corresponds approximately to an impeller used in iurbo vacuum pumps, which, due to the exit angle β 2 of about 90 °, generates practically only G-speed energy, which in turn causes the gas suction.
Für gewisse Anwendungsfälle hat es sich als vorteilhaft erwiesen, wenn die auf der Ober- und Unterseite des Mischrads befindlichen Schaufeln hinsichtlich Zahl und Größe verschieden sind· Dabei empfiehlt es sich, wenn die Schaufeln in Laufrichtung des Mischrads vorwärts gekrümmt sind und die Form eines Kreisbogens aufweisen.For certain applications it has proven to be advantageous if the blades on the top and bottom of the mixing wheel are different in number and size It is recommended that the blades are curved forwards in the running direction of the mixing wheel and have the shape of an arc of a circle exhibit.
Gemäß einem weiteren wesentlichen Merkmal der Erfindung ist unterhalb des Mischrads etwa koaxial zu diesem ein Saugrohr angeordnet. Auf diese Weise wird der Luft- bzw. Gas-Abwasser-Austauschzone ständig von der Belüftung bzw. Begasung noch nicht oder noch nicht intensiv genug erfaßtes Abwasser zugeführt. Biese verstärkte Umwälzung hat auch bei größeren Behältervolumen einen gleichmäßigeren Zustand der Flüssigkeit bzw. des Abwassere zur Folge.According to another essential feature of the invention is below of the mixing wheel arranged approximately coaxially to this a suction pipe. In this way, the air or gas-wastewater exchange zone becomes Wastewater that has not yet been or has not yet been captured intensively enough by the aeration or fumigation is constantly supplied. tuck Increased circulation has a more uniform state of the liquid or the wastewater, even with larger container volumes Episode.
