Description
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 eineThere 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-fibrous material and from which the flowing water entrains air. The water then falls, dissolved in drops, through a layer of air c, in one of them
ίο innige 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 mit einem Rohr versehen, das die Räume über und unter der Rieselschicht miteinander verbindet und ein Anstauen von Luft unter der Rieselschicht verhindert.ίο there is intimate 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 been provided with a pipe which connects the spaces above and below the trickle layer and prevents air from accumulating under the trickle layer.
Nach der Erfindung ist das Lüftrohr e oder, wenn mehrere solcher Rohre vorhanden sind, jedes von ihnen mit einer von außen her bedienbaren Absperrvorrichtung f versehen, die beim Auswaschen der Rieselschicht b nach dem Gegenstromverfahren in ihrer Schließlage die unter der Schicht b vorhandene Luft zwingt, die Filterschicht gleichzeitig mit dem Reinigungswasser zu durchstreichen. Dadurch wird eine gründlichere Reinigung der Rieselschicht von Schlamm erzielt, als sie durch das Wasser allein möglich ist. Zum Auswaschen der Rieselschicht können beliebige, in der Zeichnung nicht dargestellte Zu- und Ableitungsrohre für das Waschwasser verwendet werden.According to the invention, the Lüftrohr e or when a plurality of such tubes are provided, each of them bearing a forth operable from outside shutoff f, the b at wash out the Rieselschicht by the countercurrent method, in its closed position, the forces of the layer b existing air, to cross the filter layer with the cleaning water at the same time. This results in a more thorough cleaning of the trickle layer of sludge than is possible with the water alone. To wash out the trickle layer, any inlet and outlet pipes, not shown in the drawing, can be used for the washing water.
In der Zeichnung ist ferner ein außen liegendes Umgangsrohr mit einem Absperrventil dargestellt, das dem gleichen Zwecke dient wie das Rohr e und das mit diesem Rohre gemeinsam oder auch für sich angeordnet sein kann. Auch kann man mehrere außen liegende Umgangsrohre anwenden, deren jedes ein Ventil trägt.In the drawing, an external bypass pipe is also shown with a shut-off valve, which serves the same purpose as the pipe e and which can be arranged with these pipes together or separately. It is also possible to use several external bypass pipes, each of which carries a valve.
Die Absperrvorrichtung f kann beliebiger Art sein, z. B. ein gewöhnliches Absperrventil bilden und an beliebiger Stelle des Rohres oder der Rohre e angeordnet sein.The shut-off device f can be of any type, e.g. B. form an ordinary shut-off valve and be arranged at any point on the pipe or pipes e .
