Description

Zur Durchführung oder Beschleunigung von in Flüssigkeit stattfindenden chemischen und biologischen Vorgängen ist ein Begasen oft notwendig.To carry out or accelerate things that take place in liquid fumigation is often necessary for chemical and biological processes.

Besonders auf dem Gebiet der mikrobiologischen Eiweißsynthese existieren verschiedenartigste Belüfter, die alle eine möglichst feine Verteilung der Luft anstreben, jedoch die optimale Verteilung nicht immer erreichen.Exist especially in the field of microbiological protein synthesis A wide variety of aerators, all of which distribute the air as finely as possible aim, but do not always achieve the optimal distribution.

Im Gegensatz zu den schon bekannten Vorrichtungen, die sich gleichfalls der Abscherwirkung zum Zwecke der Gasverteilung bedienen, ermöglicht die vorliegende Erfindung die Bildung von Gasblasen in gewünschter Größe mit absoluter Sicherheit. Aus Abb. I ist ersichtlich, daß eine bekannte, rotierende Vorrichtung t Verwendung findet, z. B. ein Schraubenrührer, der in bekannter Weise die unterhalb (bei A) angesaugte Flüssigkeit in ebenfalls bekannter Weise in einem offenen, zylinderförmigen Gehäuse2 aufwärts und strahlenförmig nach außen bewegt, wobei jedoch die Flüssigkeit erfindungsgemäß an mindestens zwei waagerecht und übereinander angeordneten, durch Schlitze voneinander getrennten, stationären, ringförmigen, gasverteilenden, gelochten Hohlkörpern 3 vorübergeführt wird, so daß mittels Abscherung Gasblasen entstehen, die an den Hohlkörpern mit Sicherheit nicht noch einmal als Gas-Flüssigkeits-Gemisch abscherend wirken, da auf den einzelnen Hohlkörpern jeweils nur ein Loch in Strömungsrichtung der radial vorübergeführten Flüssigkeit vorgesehen ist.In contrast to the already known devices, which are also serve the shearing action for the purpose of gas distribution, enables the present Invention the formation of gas bubbles in the desired size with absolute certainty. From Fig. I it can be seen that a known rotating device t use finds, e.g. B. a screw stirrer, which in a known manner the below (at A) sucked liquid in a known manner in an open, cylindrical Housing 2 moved upwards and radially outwards, but with the liquid according to the invention on at least two arranged horizontally and one above the other through Slots separated from each other, stationary, annular, gas-distributing, perforated Hollow bodies 3 is passed, so that gas bubbles arise by means of shearing, the ones on the hollow bodies certainly not again as a gas-liquid mixture have a shearing effect, as there is only one hole in the direction of flow on the individual hollow bodies the radially passed liquid is provided.

Außerdem ist die Bildung der in Strömungsrichtung der Flüssigkeit unmittelbar aufeinanderfolgenden Gasblasen in der geforderten, zweckmäßigen Größe dadurch gewährleistet, daß die mittels Abscherung entstandenen Gasblasen im Durchmesser kleiner sind als der zugehörige Lochdurchmesser an der Abscherstelle und die sonst beim Abscheren auftretende Gefahr der Gasschlauchbildung ausgeschaltet ist. Wie Abb. I und II zeigen, erfolgt die Gaszufuhr von einer Hauptleitung q. aus getrennt und über ein jeweils eingebautes Regulierorgan 5 an die jedem Hohlkörper zugeordnete zentrale Verteilerkammer 6, von wo aus zwei oder mehr Verbindungsstutzen 7 an den Hohlkörper führen. Jeder Hohlkörper wird also mit der Gasmenge versorgt, die der an den Löchern abscherend wirkenden Flüssigkeitsmenge entspricht.In addition, the formation is in the direction of flow of the liquid immediately successive gas bubbles in the required, appropriate size this ensures that the gas bubbles produced by means of shearing have a diameter are smaller than the corresponding hole diameter at the shear point and the other the risk of gas hose formation occurring when shearing is eliminated. As Figs. I and II show that the gas is supplied from a main line q. from separated and via a built-in regulating member 5 to the one assigned to each hollow body central distribution chamber 6, from where two or more connecting pieces 7 to the Lead hollow body. Each hollow body is thus supplied with the amount of gas that the corresponds to the amount of liquid acting as a shear at the holes.

Durch die vorzugsweise Anordnung der gasverteilenden Löcher auf der dem natürlichen Auftrieb entgegengesetzten Seite der Hohlkörper ist weitgehend für einen Druckausgleich in den Hohlkörpern gesorgt.The preferred arrangement of the gas-distributing holes on the the side of the hollow body opposite the natural buoyancy is largely for a pressure equalization is provided in the hollow bodies.

Zwischen der untersten Schicht des (bei B) aus dem Verteiler radial austretenden Gas-Flüssigkeits-Gemisches und dem unteren Rand des Ansaugstutzens C ist ein Abstand in der Größe, daß die Gasblasen mit Sicherheit durch ihren natürlichen Auftrieb aus der Flüssigkeit entweichen und die rotierende Vorrichtung nur Flüssigkeit ansaugt.Between the lowest layer of the (at B) from the manifold radially escaping gas-liquid mixture and the lower edge of the suction nozzle C is a distance of the size that the gas bubbles can be sure of by their natural Buoyancy from the liquid escape and the rotating device only liquid sucks.
