BeschreibungDescription
Vorrichtung zum Begasen und Rühren von Flüssigkeiten.Device for gassing and stirring liquids.
Die Neuerung betrifft eine Vorrichtung zum Begasen und Mischen vom Flüssigkeiten wie Wasser, Abwasser, Chemieschesubsanzen und dergleichen.The innovation concerns a device for gassing and mixing liquids such as water, waste water, chemical substances and the like.
Bei bekannten Vorrichtungen dieser Art, die für die Begasung von Flüssigkeit eingesetzt sind, wird immer ein sehr großer Teil des Gases "ungenutzt" auf der Oberfläche der behandelten Flüssigkeit herraus gedruckt.In known devices of this type, which are used for the gassing of liquids, a very large part of the gas is always pressed out "unused" on the surface of the treated liquid.
Abglsehen davon, daß dies unerwünscht ist, (langer Begasungsprozeß) führt der kleine Wirkungsgrad zum höhen Energieverbrauch. Despite the fact that this is undesirable (long gassing process), the low efficiency leads to higher energy consumption.
Es ist die Aufgabe der Neuerungs eine gattungsgemäße Vorrichtung so zu verbessern, daß ein Wirkungsgrad viel höher liegt und die Begasungskosten zu minimieren.The aim of the innovation is to improve a generic device so that the efficiency is much higher and the gassing costs are minimized.
Die Aufgabe wird neuerungsgemäß durch folgende Merkmale gelöst:The task is solved according to the innovation by the following features:
a) an der Welle des Antriebswerkes ist eine Hohlwelle angekuppelt deren Ende mit einem Hohlenrührorgan versehen ist;a) a hollow shaft is coupled to the drive shaft the end of which is provided with a hollow stirring element;
b) der gemeinsamer Innenraum der Welle und des Rührorgans ist einerseits mit einer Gassaugleitung und anderseits mit einen Ausschleuderbohrungen oder deren gleichen versehen.b) the common interior of the shaft and the agitator is provided on the one hand with a gas suction line and on the other hand with an ejection bore or similar.
Bei einer bevorzugten Ausführungsform der Neuerung ist zur Verbesserung der Begasung von Flüssigkeit bei minimalen Energieeinsatz die Fliehkraft ausgenutzt.In a preferred embodiment of the innovation, centrifugal force is used to improve the aeration of liquid with minimal energy consumption.
Die nachstehende Beschreibung dient im Zusammenhang mit beiliegender Zeichnung der weiteren Erleuchterung. Es zeigen:The following description, in conjunction with the attached drawing, serves to provide further clarification. They show:
Fig.l eine Schaubildliche Ansicht einer Begasungs- und RührvorrichtungFig.l a diagrammatic view of a gassing and stirring device
Fig.2 eine Schnittansicht des RührersFig.2 a sectional view of the stirrer
Ein Rührorgan 2 mit einem Innenraum und Ausblasungsbohrungen 5 ist über eine Hohlwelle 3 durch ein Antriebswerk 1 rotierend angetrieben. Die Welle und Rührer bestehen vorzugsweise aus Stahl. Die Hohlwelle 3 ist drehbar über einer Saugleitung 4 mit Gasquelle verbunden. Die Leitung 4 und der Innenraum der Welle 3 stellt damit eine Verbindung zum Innenraum des Rührorgans 2 und behandelten Flüssigkeit her. Die Gassaugleitung ist mit einer klein dimmensionierten Bohrung 5 versehen. Dadurch ist eine geringe Menge Flüssigkeit im Innenraum der Welle und Rührer eingesaugt, und mit dem Gas zusammen durch, die Druckbohrungen 5 heraus geschleudert wird. Somit kann im Innenraum der Welle 5 zum zwecke des Ansauges vom Gas ein Unterdruck erzeugt werden. Als Antriebswerke 1 können alle möglichen Antriebe, vom Elektrotauchmotoren (wie Fig.l zeigt) bis Wasserturbienen, eingesetzt werden. Die Begasungsprozess benötigt fast keine zusätzliche Energie. Zum Ansaugen und Verteilen vom Gas in Flüssigkeiten ist der Fliehkraft der Gas- Flüssigkeitteilchen ausgenutzt.A stirring element 2 with an interior and blow-out holes 5 is driven in rotation by a drive mechanism 1 via a hollow shaft 3. The shaft and stirrer are preferably made of steel. The hollow shaft 3 is rotatably connected to a gas source via a suction line 4. The line 4 and the interior of the shaft 3 thus establish a connection to the interior of the stirring element 2 and the treated liquid. The gas suction line is provided with a small-dimensioned hole 5. As a result, a small amount of liquid is sucked into the interior of the shaft and stirrer and is thrown out together with the gas through the pressure holes 5. In this way, a negative pressure can be generated in the interior of the shaft 5 for the purpose of sucking in the gas. All possible drives, from electric submersible motors (as shown in Fig. 1) to water turbines, can be used as drive mechanisms 1. The gassing process requires almost no additional energy. The centrifugal force of the gas-liquid particles is used to suck in and distribute gas in liquids.
Die beschriebene Vorrichtung wird in folgeder Weise funktionieren:The device described will work as follows:
Ein Rührreaktor, Rührbehälter oder dergleichen ist kontinuierlich oder beatchweise mit der behandelten Flüssigkeit zu füllen. Der Rührorgan 2 und Welle 3 ist mittels des Antriebs 1 gedreht. Die Gas- Flüssigkeitteilchen sind durch die Bohrungen ist aus dem Innenraum des Rührer 2 herraus geschleudert. Somit entsteht Unterdruck im Innenraum des Rührers 2, der Welle 3 und der Leitung 4. Durch den in den Innenräumen herrschenden Unterdruck wird das Gas und die Flüssigkeit (vom ca. 25% bis 40% Gesamtvollumen) in das Innere der Welle und des Rührers eingesaugt und gelangt von da über die Äusschleuderbohrungen 5 in der behandelten Flüssigkeit.A stirred reactor, stirred tank or the like is to be filled continuously or in batches with the treated liquid. The stirring element 2 and shaft 3 are rotated by means of the drive 1. The gas-liquid particles are ejected through the holes from the interior of the stirrer 2. This creates a negative pressure in the interior of the stirrer 2, the shaft 3 and the line 4. Due to the negative pressure prevailing in the interiors, the gas and the liquid (from approx. 25% to 40% of the total volume) are sucked into the interior of the shaft and the stirrer and from there reach the treated liquid via the ejection holes 5.
Somit ist ein Rühren und Begasen sichergestellt.This ensures stirring and gassing.
Es hat sich gezeigt, daß an einer gemeinsamen Hohlwelle mehrere separate Rührorgane und Begasungsvorrichtungen angebracht werden können.It has been shown that several separate stirring elements and gassing devices can be attached to a common hollow shaft.
