Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Belüftung einer Flüssigkeit, vorzugsweise auf dem Gebiet der Wasseraufbereitung und insbesondere der Entsäuerung von Wasser.The Invention relates to a device for aeration of a liquid, preferably in the field of water treatment and in particular the deacidification of water.
Unter Entsäuerung von Wasser ist die Verminderung der Konzentration des in Wasser gelösten Kohlenstoffdioxids zu verstehen. Hierbei soll der pH-Wert des Wassers erhöht werden, um die korrosionschemischen Eigenschaften des Wassers gegenüber metallischen Werkstoffen, z. B. den Rohrleitungen in einem Trinkwassersystem, zu verbessern.Under deacidification Water is the reduction of the concentration of water dissolved carbon dioxide to understand. Here, the pH of the water should be increased, to the corrosion-chemical properties of water over metallic Materials, eg. B. the pipelines in a drinking water system, to improve.
Im Stand der Technik sind verschiedene Verfahren und Vorrichtungen zur Entsäuerung des Wassers bekannt. Zum Beispiel können Verdüsungsverfahren, Kaskadenbelüftung oder Verfahren mit Flachbelüftern verwendet werden.in the State of the art are various methods and devices for deacidification known of the water. For example, atomization, cascade aeration or Procedure with flat aerators be used.
Bei bekannten Flachbelüftern wird Luft über einen Luftverdichter mit einem bestimmten Druck in ein System aus Rohren gegeben, die aus einem feinporigen Werkstoff, z. B. aus Sinterkeramikmaterial, bestehen und vom zu entsäuernden Wasser umspült werden.at known Flachbelüftern will air over one Air compressor with a certain pressure in a system of pipes given, which consists of a fine-pored material, for. B. sintered ceramic material exist and to be deacidified Water is washed around.
Die für die Belüftung verwendeten Sinterkeramikrohre sind herstellerseitig nur in Ausführungen lieferbar, die beidseitig offen sind, was zu der Notwendigkeit führt, entsprechende Dichtelemente an den Stirnseiten der Rohre vorzusehen, die dem Luftverdichterdruck ausgesetzt sind.The for the ventilation used sintered ceramic tubes are only available in versions by the manufacturer, which are open on both sides, which leads to the need to appropriate Provide sealing elements on the front sides of the tubes, the air compressor pressure are exposed.
Es kommt hinzu, dass die Sinterkeramikrohre herstellungsbedingte Längenabweichungen aufweisen und darüber hinaus die Stirnflächen der Sinterkeramikrohre nicht planar abschliessen und sogar gegenüber dem Rohrradialschnitt angeschrägt sein koennen. Diese herstellungsbedingten Toleranzen können eine funktionssichere Abdichtung der Sinterkeramikrohre an ihren Stirnflächen erschweren.It is added that the sintered ceramic tubes production-related length deviations and above beyond the end faces the sintered ceramic tubes do not finish planar and even against the Tapered radial section bevelled could be. These manufacturing tolerances can be a Functionally reliable sealing of the sintered ceramic tubes complicate their faces.
Um die gewünschten Entsäuerungswirkungsgrade zu erzielen, muss ein bestimmter Luftdurchsatz vorhanden sein. Um diesen zu erzielen, werden bei bekannten Entsäuerungsanlagen Seitenkanalverdichter verwendet. Diese weisen jedoch den Nachteil auf, dass sie einen relativ geringen Wirkungsgrad und damit hohen Energieverbrauch aufweisen.Around the desired Entsäuerungswirkungsgrade to achieve a certain air flow rate must be present. Around To achieve this, are in known deacidification side channel blower used. However, these have the disadvantage that they have a have relatively low efficiency and thus high energy consumption.
Der Luftdurchsatz wird bei bestehenden Flachbelüftern zudem dadurch beeinträchtigt, dass stangenförmige Halteelemente, die die Keramikrohre an den beiden Seiten eines vom Seitenkanalverdichter gespeisten zentralen Luftzuführungselements befestigen, innerhalb der Keramikrohre verlaufen, was einerseits den für den Luftdurchfluss zur Verfügung stehenden Querschnitt der Keramikrohre vermindert und andererseits zu einer Druckminderung durch Verwirbelungen führt. Ein weiteres Problem besteht dann, dass die bisherigen Abdichtungen an den Stirnseiten der Keramikrohre unzureichend sind. Hier kann es zu einem Druckabfall kommen, der durch eine entsprechend höhere Einspeisung durch den Luftverdichter kompensiert werden muss.Of the Airflow is also affected by existing flat ventilators, that rod-shaped Holding elements that hold the ceramic tubes on both sides of a Side channel compressor fed central air supply element fasten, run inside the ceramic tubes, on the one hand the for the air flow available Cross-section of the ceramic tubes reduced and on the other hand to a Pressure reduction by turbulence leads. Another problem is that the previous seals on the front sides of the ceramic tubes are insufficient. This can lead to a pressure drop, the by a correspondingly higher Infeed must be compensated by the air compressor.
Ausgehend davon stellt sich die Erfindung die Aufgabe, den Energieverbrauch derartiger Flachbelüfter bei gleicher Entsäuerungsleistung wesentlich zu vermindern.outgoing Of these, the invention sets itself the task of energy consumption Such Flachbelüfter at the same deacidification performance to significantly reduce.
Eine weitere Aufgabe der Erfindung liegt dann, den Luftdurchfluß des Flachbelüfters zu verbessern und die Abdichtung der Keramikrohre zu optimieren.A Another object of the invention is then to the air flow of Flachbelüfters improve and optimize the sealing of ceramic pipes.
Diese Aufgabe wird gelöst durch eine Vorrichtung zur Belüftung einer Flüssigkeit mit den Merkmalen gemäß Anspruch 1 sowie mit den Merkmalen gemäß Anspruch 10.These Task is solved by a device for ventilation a liquid with the features according to claim 1 and with the features of claim 10th
Ein Kern der Erfindung besteht dann, dass das Halteelement zur Befestigung der Belüftungshohlkörper an dem Luftzuführungselement außerhalb des Belüftungshohlkörpers angeordnet ist.One Core of the invention is then that the retaining element for attachment the ventilation hollow body the air supply element outside arranged the ventilation hollow body is.
Hierdurch wird verhindert, dass der effektive Durchflussquerschnitt der Keramikrohre beeinträchtigt ist.hereby will prevent the effective flow cross section of the ceramic tubes impaired is.
Gemäß einer Ausführungsform der Erfindung ist ein Trägerelement vorgesehen, das die Belüftungshohlkörper stirnseitig abschließt. Hierbei ist zwischen dem Trägerelement und der Stirnseite des Belüftungshohlkörpers ein Dichtring schwimmend gelagert, wobei darüber hinaus eine Manschette vorgesehen sein kann, die die Stirnseite, den schwimmenden Dichtring einschließend, übergreift.According to one embodiment The invention is a carrier element provided that the ventilation hollow body frontally concludes. Here is between the carrier element and the front side of the ventilation hollow body Sealing ring floating, in addition, a cuff can be provided, the front side, the floating sealing ring including, overlaps.
Gemäß einer bevorzugten Ausführungsform der Erfindung ist zwischen dem Trägerelement und dem schwimmenden Dichtring eine verstellbare, in der Manschette geführte Stempelplatte angeordnet, die vorzugsweise über einen in dem Trägerelement angeordneten Gewindemechanismus verstellbar ist.According to one preferred embodiment of Invention is between the carrier element and the floating seal an adjustable, in the cuff guided Stamp plate arranged, preferably arranged over a in the carrier element Threading mechanism is adjustable.
Diese erlaubt es, die Dichtwirkung des Dichtelements an jeder Stirnseite des Belüftungshohlkörpers in Abhängigkeit von den Herstellungstoleranzen der Sinterkeramikrohre und gegebenenfalls des in diesen herrschenden Luftdrucks funktionssicher einzustellen, so dass an den Stirnseiten kein Druckabfall auftritt.These allows the sealing effect of the sealing element on each end face of the ventilation hollow body in dependence from the manufacturing tolerances of the sintered ceramic tubes and optionally to function reliably in the prevailing atmospheric pressure, so that no pressure drop occurs at the end faces.
Da einerseits die Belüftungshohlkörper sehr gut abgedichtet werden können und andererseits der effektive Durchflussquerschnitt der Belüftungshohlkörper nicht beeinträchtigt wird, ist der Einsatz eines Luftverdichters möglich, der unter Beibehaltung oder sogar Erhöhung des Entsäuerungswirkungsgrads einen im Vergleich zu Seitenkanalverdichtern reduzierten oder geringeren Luftdruck erzeugt.Since on the one hand the ventilation hollow body can be sealed very well and on the other hand, the effective flow area of the ventilation hollow body is not compromised, the use of an air compressor is possible, which produces while maintaining or even increase the deacidification efficiency reduced or lower compared to side channel compressors air pressure.
Dieses ermöglicht den Einsatz eines Radialventilators, der preisgünstiger als ein Seitenkanalverdichter ist und überdies einen wesentlich geringeren Energieverbrauch als ein Seitenkanalverdichter aufweist. Dies führt z. B. bei den in der Trinkwasseraufbereitung üblichen Wasservolumina zu erheblichen Kosteneinsparungen.This allows the use of a centrifugal fan, which is cheaper than a side channel blower is and moreover a much lower energy consumption than a side channel blower having. this leads to z. As in the usual in drinking water treatment volumes of water to significant cost savings.
