Abstract
Description
Anwendungsgebietfield of use
Gegenstand der Erfindung ist eine Belüftungsturbine mit Schaumzerstörer zum Belüften von Flüssigkeiten mit schaumbildenden Inhaltsstoffen.object The invention is a ventilation turbine with foam destroyer for ventilation of liquids with foam-forming ingredients.
Die Anwendungsgebiete beziehen sich auf die mikrobiologische Reinigung von hochverschmutzten Abwässern aus der chemischen Industrie, der industriellen Tierproduktion und der Herstellung von Nahrungsmitteln.The Areas of application relate to microbiological purification of highly polluted wastewater from the chemical industry, industrial animal production and the production of food.
Charakterisierung der bekannten technischen LösungenCharacterization of the known technical solutions
Zur Beherrschung der Abwasserprobleme spielen Belüftungskreisel und Belüftungsturbinen eine besondere Rolle. Durch den Eintrag von Luft werden den Mikroorganismen Lebensbedingungen geschaffen, die zur Umwandlung von gelösten Substanzen in Biomasse und damit zur Reinigung des Abwassers führen.for Control of wastewater problems play aeration gyros and aeration turbines special role. By the entry of air become the microorganisms Created conditions for the conversion of dissolved substances in biomass and thus lead to the purification of the wastewater.

Nachteilig an diesen drei Lösungen ist, daß der Schaum die vom mikrobiologischen Prozeß vom Sauerstoffgehalt her verbrauchte Luft mitführt und diese Luft durch die Zerstörung des Schaumes im Zentrifugalfeld freigesetzt und in den Prozeß zurückgeführt wird.adversely at these three solutions is that the Foam the oxygen content from the microbiological process entrains used air and this air through the destruction of the foam in the centrifugal field is released and returned to the process.
Ziel der ErfindungObject of the invention
Das Ziel der Erfindung ist es, eine Vorrichtung vorzustellen, bei der die Frischluft über einen eigenen Weg in die zu belüftende Flüssigkeit gelangt und die verbrauchte Luft nicht in den Vorgang der Belüftung der Flüssigkeit zurückgeführt wird.The The aim of the invention is to provide a device in which the fresh air over a separate way to be ventilated liquid does not get into the process of aeration and the spent air liquid is returned.
Damit wird den Mikroorganismen ständig neuer Sauerstoff zugeführt, die Umsetzung der abzubauenden Stoffe aktiviert und der Prozeß mit geringerem Energieaufwand betrieben.In order to is getting more and more new to microorganisms Supplied with oxygen, the implementation of the degraded substances activated and the process with less Energy expenditure operated.
Merkmale der ErfindungFeatures of invention
Es wurde erkannt, daß im Bereich der Zerstörung des Schaumes die entweichende sauerstoffarme Luft immer noch die Rotationsenergie besitzt und daher von der Rotationsachse weg nach außen befördert wird.It it was recognized that in Area of destruction Foam escaping oxygen-poor air still Has rotational energy and therefore away from the axis of rotation transported outside.
Die erforderliche Frischluft wird dagegen noch rotationslos angesaugt und nimmt aus diesem Grunde einen dicht an der Hohlwelle entlang führenden Strömungsweg.The required fresh air, however, is sucked in still without rotation and therefore takes a close along the hollow shaft leading Flow path.
Die Merkmale der Erfindung zeichnen sich dadurch aus, daß die Achse der Belüftungsturbine als Hohlwelle ausgebildet wird und im mittleren Bereich Luftansaugöffnungen besitzt. Die Flügel der Belüftungsturbine befinden sich an der Unterseite einer Abdeckung, die eine Durchlaßöffnung zur Hohlwelle besitzt. Über der Abdeckung befindet sich ein über flügelartige Rippen verbundener zylindrischer Mantel. Nach obenhin enden die Rippen kurz unter den Luftansaugöffnungen. Damit ist der Bereich der Belüftungsturbine vom Bereich der Schaumzerstörung getrennt. Da die flügelartigen Rippen durch ihre Ventilationswirkung ständig frische Luft ansaugen kann keine verbraucht Luft in die Turbine gelangen.The Features of the invention are characterized in that the axis the ventilation turbine as Hollow shaft is formed and in the central region Luftansaugöffnungen has. The wings the ventilation turbine are located at the bottom of a cover, which has a passage opening to the Hollow shaft has. about The cover is an over wing-like Ribbed connected cylindrical shell. To the top end the Ribs just below the air intake openings. This is the area of the ventilation turbine separated from the area of foam destruction. Because the wing-like Ribs constantly suck in fresh air due to their ventilation effect Can not get used air into the turbine.
Zur Abführung der sich aus dem Schaum bildenden Flüssigkeit sind im unteren Bereich des Mantels zur Abdeckung hin Schlitze vorhanden.for removal the liquid forming the foam is in the lower part slits available to cover towards the cover.
Um zu vermeiden, daß Flüssigkeit nicht im oberen Bereich des Mantels herausspritzt, ist dieser Weg nach oben durch einen Ring begrenzt.Around to avoid that liquid does not squirt out in the upper part of the coat, this way bounded above by a ring.
Dieser Ring kann auch aus sich überlappenden flügelartigen Ringsegmenten hergestellt sein, die den vertikalen Transport des Schaumes in die Vorrichtung unterstützen.This Ring can also be overlapping wing-like Ring segments are made, which the vertical transport of the Support foam in the device.
