Abstract

The filter vessel contains granular filter material and serves to treat water. At the bottom, the filter vessel has a closable outlet. To remove the filter material outside the filter operation, compressed air is passed into the vessel, as a result of which the filter material, together with water, is displaced through the outlet. The vessel can be provided in the lower region with a gas-permeable plate, the opening of the outlet being in the plate and the feed line for compressed air being situated beneath the plate.

Description

Die Erfindung betrifft ein Verfahren zum Entleeren eines körniges Filtermaterial und Wasser enthaltenden Filterbe­ hälters, der am Boden einen verschließbaren Auslaß auf­ weist, sowie einen entsprechend ausgestalteten Filterbe­ hälter.The invention relates to a method for emptying a granular filter material and filterbe containing water holder that has a lockable outlet on the bottom has, and a correspondingly designed filterbe holder.

Soll das körnige Filtermaterial, z.B. Aktivkohle, zum Rei­ nigen aus dem Filterbehälter entfernt werden, so ist es üblich, durch Einleiten von Wasser das Material aus dem Behälter auszuspülen. Dabei ist jedoch eine große Wasser­ menge nötig, die neben dem Filtermaterial auch selbst an­ schließend gereinigt werden muß, weil sie durch den Kon­ takt mit dem verschmutzten Filtermaterial Schmutzanteile aufnimmt. Bei diesem bekannten Verfahren muß somit eine große Menge verschmutzten Wassers gespeichert und gerei­ nigt werden.If the granular filter material, e.g. Activated carbon, for rice are removed from the filter container, so it is usual, by introducing water the material from the Rinse out the container. However, there is a large water amount necessary, in addition to the filter material itself must finally be cleaned because it is through the Kon interacts with the dirty filter material records. In this known method, a Large quantities of polluted water are stored and cleaned be inclined.

Der Erfindung liegt die Aufgabe zugrunde, das Entleeren des Filterbehälters auf einfache Weise durchzuführen und die dabei anfallende Wassermenge gering zu halten. Beim eingangs genannten Verfahren geschieht dies erfindungsge­ mäß dadurch, daß man das Filtermaterial zusammen mit Was­ ser durch Einleiten von Druckluft durch den Auslaß aus dem Behälter verdrängt. Der erfindungsgemäß ausgestaltete Fil­ terbehälter ist zu diesem Zweck mit mindestens einer Druckluftzufuhr versehen. Durch Verwenden der Druckluft fällt üblicherweise zusammen mit dem Filtermaterial, das gereinigt werden muß, nur eine solche Wassermenge an, die höchstens dem Volumen des Filterbehälters entspricht.The invention has for its object the emptying of the filter container in a simple manner and to keep the amount of water generated low. At the The method mentioned at the beginning is done according to the invention moderately in that the filter material together with what water by introducing compressed air through the outlet from the  Container displaced. The fil designed according to the invention For this purpose, the container is equipped with at least one Provide compressed air supply. By using compressed air usually coincides with the filter material that must be cleaned, only such an amount of water that corresponds at most to the volume of the filter container.

Wenn der Filterbehälter mit einem im unteren Bereich ange­ ordneten gasdurchlässigen, das Filtermaterial tragenden Boden ausgerüstet ist, wobei sich die Mündung des Auslas­ ses im Boden befindet, leitet man die Druckluft zweckmäßi­ gerweise von unten durch den Boden in den Bereich des Fil­ termaterials und verdrängt so Wasser und Filtermaterial durch den Auslaß hindurch nach außen.If the filter container is marked with a in the lower area arranged gas-permeable, carrying the filter material Floor is equipped, with the mouth of the outlet ses in the ground, one conducts the compressed air appropriately from below through the floor into the area of the fil termaterials and thus displaces water and filter material out through the outlet.

Man kann das aus dem Filterbehälter verdrängte Filterma­ terial-Wasser-Gemisch zum Abtransport z.B. in einen Silo­ wagen leiten, dabei ist es zweckmäßig, mit dem Silowagen die Einrichtung zum Erzeugen der Druckluft, z.B. einen Kompressor, mitzuführen.You can see the Filterma displaced from the filter container material-water mixture for removal e.g. in a silo lead wagons, it is advisable to use the silo wagon the device for generating the compressed air, e.g. one Compressor to carry.

Bei dem im Behälter befindlichen Filtermaterial handelt es sich z.B. um Aktivkohle mit dem Körnungsbereich von etwa 0,5 bis etwa 4 mm, doch ist das Verfahren und die Vorrich­ tung selbstverständlich auch für andere körnige Filterma­ terialien und auch andere Flüssigkeiten als Wasser ver­ wendbar.The filter material in the container is concerned e.g. around activated carbon with the grain size range of about 0.5 to about 4 mm, but is the procedure and the Vorrich of course also for other granular filter dimensions materials and liquids other than water reversible.

Einzelheiten des Verfahrens und der Vorrichtung werden mit Hilfe der Zeichnung erläutert.Details of the method and the device are provided with Help explained in the drawing.

Der Filterbehälter 1 weist einen gasdurchlässigen Boden 2, z.B. einen Düsenboden, auf, auf welchem sich ein Bett 3 eines körnigen Filtermaterials befindet. Bei dem Filterma­ terial kann es sich z.B. um Aktivkohle handeln. Das Fil­ termaterial dient zum Reinigen einer Flüssigkeit, insbe­ sondere Wasser, die durch einen Einlaß 5 in den Behälter 1 eintritt und ihn durch einen unteren Abfluß 6 verläßt. Der Filterbehälter kann prinzipiell auch in anderer Richtung als der in der Zeichnung dargestellten durchflossen wer­ den. Beim Bett 3 des Filtermaterials handelt es sich übli­ cherweise um ein Festbett, doch ist auch ein Wirbelbett möglich.The filter container 1 has a gas-permeable base 2 , for example a nozzle base, on which there is a bed 3 of a granular filter material. The filter material can be activated carbon, for example. The Fil termmaterial is used to clean a liquid, in particular special water, which enters the container 1 through an inlet 5 and leaves it through a lower drain 6 . The filter container can flow in principle in a different direction than that shown in the drawing. Bed 3 of the filter material is usually a fixed bed, but a fluidized bed is also possible.

Wenn das Filtermaterial durch den Reinigungsbetrieb ver­ schmutzt ist und ausgewechselt oder regeneriert werden muß, werden zunächst der Einlaß 5 und der Abfluß 6 abge­ sperrt. Dann wird im Auslaß 7 das Ventil 8 geöffnet und Druckluft durch die Leitung 9 über das geöffnete Ventil 10 zunächst in den unteren Bereich des Behälters 1 und dann durch den gasdurchlässigen Boden 2 nach oben gedrückt. Da­ bei wird das Bett 3, sofern es sich um ein Festbett han­ delt, etwas aufgewirbelt und dadurch gelockert, gleichzei­ tig entsteht im oberen Bereich des Behälters 1 ein Luft­ polster 12, dessen Volumen sich vergrößert. Das Luftpol­ ster 12 drückt das Wasser zusammen mit dem Filtermaterial zur Mündung 7 a des Auslasses 7 und durch den Auslaß hin­ durch nach außen zu einem nicht dargestellten Auffangbe­ hälter.If the filter material is dirty by the cleaning operation and needs to be replaced or regenerated, the inlet 5 and the drain 6 are first blocked. Then the valve 8 is opened in the outlet 7 and compressed air is pressed through the line 9 via the opened valve 10 first into the lower region of the container 1 and then through the gas-permeable base 2 upwards. Since the bed 3 , provided it is a fixed bed, swirled up a little and thereby loosened, at the same time, an air cushion 12 is created in the upper region of the container 1 , the volume of which increases. The Luftpol ster 12 presses the water together with the filter material to the mouth 7 a of the outlet 7 and through the outlet through outwards to a not shown Auffangbe container.

Falls erforderlich, kann zusätzliche Druckluft durch die gestrichelte Leitung 13 in den oberen Bereich des Behäl­ ters 1 eingeleitet werden; es ist auch möglich, die Druck­ luft allein durch die Leitung 13 heranzuführen und auf die Leitung 9 zu verzichten. Abweichend von der Zeichnung kann die Druckluft auch an anderer Stelle in den Behälter 1 ge­ leitet werden. Dadurch daß man Druckluft aber durch die Leitung 9 von unten zunächst durch den Boden 2 leitet, er­ reicht man eine vorteilhafte Auflockerung des Bettes 3 des Filtermaterials, so daß dieses Material durch das zum Aus­ laß 7 fließende Wasser vollständig aus dem Behälter 1 ent­ fernt wird.If necessary, additional compressed air can be introduced through the dashed line 13 in the upper region of the container 1 ; it is also possible to bring the compressed air through line 13 alone and to dispense with line 9 . Deviating from the drawing, the compressed air can also be conducted elsewhere in the container 1 ge. By pressurizing air through line 9 from the bottom through the bottom 2 , it is sufficient to loosen the bed 3 of the filter material, so that this material is completely removed from the container 1 by the water flowing to 7 .
