Die Neuerung betrifft Leichtflüssigkeitsabscheider kleiner Nenngröße, insbesondere mit einem quer in den Durchflußquerschnitt gestellten Einsatz zur Koaleszenz der mit dem Abwasser mitgeführten Leichtflussigkeitsdispersion. Es gibt Anwendungsfälle, in denen größere Abwassermengen mit geringer Verschmutzung stoßweise anfallen. Hierher gehören z.B. Bilgenabwässer auf Schiffen, die mit Maschinen- und Getriebeöl, Motorkraftstoffresten und Schmiermittel verschmutzt sind. Nach dem Abwasseranfall müßte ein wesentlich größerer Abscheider eingebaut werden. Dies kann jedoch vermieden werden, wenn neuerungsgemäß dem Abscheider ein Einfüllgefäß mit einer Auslaufdrossel vorgeschaltet wird. Die Drossel bewirkt, daß der Abscheider mit einer geringen Zulaufmenge beaufschlagt wird und demnach in der Nenngröße herabgesetzt werden kann. Der Auslaufdrossel kann auch noch ein Grobfilter vorgeschaltet werden, so daß grobe Schmutzstoffe schon dort zurückgehalten werden und den Koaleszenzeinsatz des Abscheiders nicht mehr zusetzen können.The innovation affects light liquid separators with a small nominal size, in particular with an insert placed across the flow cross-section for coalescing the light liquid dispersion carried along with the waste water. There are applications in which large quantities of waste water with low levels of contamination occur in bursts. This includes, for example, bilge waste water on ships that are contaminated with engine and gear oil, engine fuel residues and lubricants. After the waste water has accumulated, a much larger separator would have to be installed. However, this can be avoided if, in accordance with the innovation, a filling vessel with an outlet throttle is installed upstream of the separator. The throttle means that the separator is supplied with a small inflow quantity and can therefore be reduced in nominal size. A coarse filter can also be installed upstream of the outlet throttle so that coarse contaminants are retained there and can no longer clog the coalescence insert of the separator.
Die Abbildungen zeigen einen neuerungsgemäß ausgestatteten Leichtflüssigkeitsabscheider im Längs- (Fig. 1) und Querschnitt (Fig. 2). Es handelt sich um ein überlicherweise aus Gußeisen hergestelltes Abscheidergehäuse 1 mit angeformten Zu- (2) und Ablaufstutzen 3 und den üblichen strömungsführenden Armaturen 4 und Tauchwänden 5. Dem untenliegenden Auslauf ist der in einem Käfig 7 geführte Schwimmer 8 mit Schließventil 9 vorgeschaltet. Ein seitlich abgehendes Handventil dient dem Abzug der angesammelten Leichtflüssigkeit. Zwischen Zulaufarmatur 4 und Käfig 7 steht der als offenporiger Schaumkunststoff ausgebildete Koaleszenzeinsatz 11, der in seitliche Führungsleisten 12 gesteckt ist und zur Reinigung herausgenommen werden kann.The illustrations show a light liquid separator equipped with the new features in longitudinal (Fig. 1) and cross-section (Fig. 2). It is a separator housing 1, usually made of cast iron, with molded inlet (2) and outlet nozzles 3 and the usual flow-guiding fittings 4 and baffles 5. The bottom outlet is preceded by the float 8 with a closing valve 9, which is guided in a cage 7. A hand valve leading off to the side is used to drain the accumulated light liquid. Between the inlet fitting 4 and the cage 7 is the coalescence insert 11, made of open-pore foam plastic, which is inserted into lateral guide rails 12 and can be removed for cleaning.
An den Zulauftutzen 2 ist ein mindestens 10 1 fassendes Einfüllgefäß 13 angeschlossen und zwar mittels eines 90°Bogens Das zylindrisch ausgeformte Gefäß besitzt im Boden eine Auslaufdrossel (Lochblende 15) auf die ein Grobfilter 16 gelegt ist, das aus demselben Material wie der Koaleszenzeinsatz besteht und zum Reinigen (Abspritzen) herausgenommen werden kann. Das Einfüllgefäß kann andere Formen haben, z.B. Kegelstumpfförmig aussehen. Das Grobfilter ist dann leichter zu entnehmen.A filling vessel 13 with a capacity of at least 10 litres is connected to the inlet nozzle 2 by means of a 90° bend. The cylindrical vessel has an outlet throttle (perforated plate 15) in the bottom onto which a coarse filter 16 is placed, which is made of the same material as the coalescence insert and can be removed for cleaning (spraying). The filling vessel can have other shapes, e.g. be truncated cone-shaped. The coarse filter is then easier to remove.
