KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Es sind in einem geschlossenen Behälter angeordnete Enteisenungsvorrichtungen bekannt, bei denen das aus einem Verteilerrohr α kommende, zu reinigende Wasser durch eine Rieselschicht b läuft, die aus feinkörniger oder feinfaseriger Masse besteht und aus der das durchströmende Wasser Luft mitreißt. Hierauf fällt das Wasser, in Tropfen aufgelöst, durch eine Luftschicht c, in der eine innigeThere are known de-ironing devices arranged in a closed container, in which the water to be cleaned, coming from a manifold α , runs through a trickle layer b , which consists of fine-grained or fine-fiber mass and from which the flowing water entrains air. The water then falls, dissolved in drops, through a layer of air c, in which an intimate
ίο Berührung mit dem Sauerstoff der Luft zum Zwecke der Oxydation stattfindet. Das Wasser sammelt sich sodann auf der oberen Schicht eines Filters d, das das ausgeschiedene Eisenhydroxyd zurückhält. Auch hat man solche Vorrichtungen bereits mit einem Rohre versehen, das den Raum über der Rieselschicht b mit dem Luftraum c unter ihr verbindet und das ein Anstauen von Luft unterhalb der Rieselschicht verhindert. Steigt in einer sol-ίο There is contact with the oxygen in the air for the purpose of oxidation. The water then collects on the upper layer of a filter d, which holds back the precipitated iron hydroxide. Such devices have also already been provided with a pipe which connects the space above the trickle layer b with the air space c below it and which prevents air from accumulating below the trickle layer. Rises in a sol-
ao chen Vorrichtung das sich auf der Filterschicht d ansammelnde Wasser aus irgendeinem Grunde bis an die untere Mündung des Luftrohres oder darüber hinaus, so wird die Tätigkeit dieses Rohres vollständig ausgeschaltet, und es entsteht in dem unteren Räume c ein Überdruck, der die Berieselung stört. In addition, the water that collects on the filter layer d for some reason up to the lower mouth of the air pipe or beyond, the activity of this pipe is completely switched off, and an overpressure arises in the lower space c, which disturbs the irrigation.
Dieser Übelstand wird nach der Erfindung dadurch vermieden, daß das' Luftrohr e im unteren Teile mit Durchbrechungen f versehen wird, die der Luft auch dann noch Einlaß in das Rohr gewähren, wenn das Wasser bereits bis an die Rieselschicht b gestiegen ist.This inconvenience is avoided according to the invention in that the 'air pipe e is provided in the lower part with openings f , which allow the air to enter the pipe even when the water has already risen to the trickle layer b.
Statt des einen mit den Durchbrechungen f versehenen Luftrohres können auch mehrere angeordnet sein.Instead of the one air tube provided with the openings f , several can also be arranged.
