Abstract
Description
Die Erfindung betrifft eine Anordnung zur Enteisenung von Brauchwasser, umfassend ein im Brauchwasserzulauf angeordnetes Behältnis mit Filterkies, durch das das Brauchwasser strömt und wobei sich das Eisen an dem Kies ablagert.The invention relates to an arrangement for iron removal of process water, including one in the process water supply arranged container with filter gravel, through which the process water flows and where the iron deposited on the gravel.
Aus dem Stand der Technik sind hinreichend Enteisenungsanlagen bekannt, die im Wesentlichen aus einem rohrförmigen Behältnis bestehen, in dem eine Kiesschüttung vorgehalten wird. Das zur Brauchwasserversorgung beispielsweise aus dem Erdreich gepumpte Wasser durchströmt, bevor es in das Hauswasserleitungsnetz eingespeist wird, einen sogenannten Enteisenungsfilter. Dieser Filter besteht im Wesentlichen aus einem Rohr, in dem eine Kiesschüttung vorgehalten wird. Infolge der dichten Kiesschüttung in dem Rohr, das auch eine entsprechende Querschnittserweiterung aufweist, wird die Strömungsgeschwindigkeit reduziert, so dass eine Ablagerung des im Wasser vorhandenen Eisens begünstigt wird.Adequate iron removal systems are from the prior art known, which consist essentially of a tubular container in which a gravel is held. For example, for the supply of process water Water pumped from the ground flows through it before it enters the domestic water supply network a so-called de-ironing filter is fed in. This filter consists essentially of a pipe in which a gravel fill is kept becomes. As a result of the dense gravel in the pipe, that too has a corresponding cross-sectional expansion, the flow rate reduced, so that a deposit of the iron present in the water favored becomes.
Bei einer derart nach dem Stand der Technik bekannten Anordnung zur Enteisenung von Brauchwasser ergibt sich das Problem, dass insbesondere bei eisenreichhaltigem Wasser, die Kiesschüttung schnell mit Eisen gesättigt ist, so dass man nicht umhin kommt, in kürzeren Abständen die Kiesschüttung zu reinigen oder entsprechend den Filter auszuwechseln.In such a state of the art Technology known arrangement for iron removal of industrial water results the problem that especially with iron-rich water, the gravel fill quickly saturated with iron is, so that one cannot avoid, the gravel fill at shorter intervals clean or replace the filter accordingly.
Hieraus ergibt sich die der Erfindung zugrunde liegende Aufgabe, eine Anordnung zur Enteisenung von Brauchwasser dahingehend zu verbessern, die wesentlich wartungsfreier arbeitet.This results in that of the invention underlying task, an arrangement for iron removal of process water to improve that, which works much more maintenance-free.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass dem Filter ein Auslassventil vorgeschaltet ist, welches mit einem an einem nachgeschalteten Druckbehälter angeordneten Druckschalter zusammenwirkt, der das Auslassventil zur zeitlich begrenzten Rückströmung öffnet. Aufgrund dieser Anordnung wird erreicht, dass das Filter einer ständigen Reinigung unterliegt, so dass die Gesamtanlage wartungsfrei arbeiten kann. Denn steigt in dem Boiler der Druck bis zu einer gewissen Grenze, wird im vorgeschalteten Bereich des Filters das Auslassventil geöffnet, so dass infolge des sich im Boiler vorhandenen Druckes das Wasser durch den Filter zurückströmt und durch den Auslass ausgetragen wird. Bei dieser Rückströmung wird insbesondere die Kiesschüttung aufgelockert, wobei infolge der Rückströmung die einzelnen Kiesel sich gegeneinander reiben, so dass sich der Kies von dem abgelagerten Eisen wieder befreit. Das abgelöste Eisen wird dann über den Ausguss ausgetragen. Ein wartungsfreies Arbeiten der Filteranordnung wird dadurch erreicht.This object is achieved according to the invention solved, that the filter is preceded by an outlet valve, which with a pressure switch arranged on a downstream pressure vessel interacts, which opens the outlet valve for a temporary backflow. by virtue of This arrangement ensures that the filter is a constant cleaning subject, so that the entire system can work maintenance-free. Because the pressure in the boiler rises to a certain limit, the outlet valve is opened in the upstream area of the filter, so that due to the pressure in the boiler, the water flows back through the filter the outlet is discharged. In this backflow, in particular gravel loosened up, the individual pebbles due to the backflow rub against each other so that the gravel separates from the deposited Iron freed again. The replaced Iron is then over poured the spout. Maintenance-free working of the filter arrangement is achieved.
In Weiterbildung der Erfindung umfasst das Behältnis für den Filterkies ein schlankes Rohr, welches bis zu zwei Dritteln seines Volumens mit Kies gefüllt ist. Aufgrund dieser geometrischen Auslegung wird eine hohe Strömungsgeschwindigkeit in dem Filter erreicht, so dass dies begünstigend ist für den Rücklauf, wobei die Masse des Kieses in dem schlanken Rohr etwa der Masse an Kies üblicher Filteranordnungen entspricht.In a further development of the invention the container for the Filter gravel is a slim tube, which can be up to two thirds of its size Volume filled with gravel is. Because of this geometric design, a high flow rate reached in the filter, so this is beneficial for the return, where the mass of the gravel in the slim pipe is approximately the mass more common on gravel Filter arrangements corresponds.
In Weiterbildung der Erfindung weist dabei das Filterrohr vorzugsweise einen Durchmesser von 90 bis 100 mm auf, wobei dessen Länge vorzugsweise etwa 1.400 mm umfasst.In a further development of the invention the filter tube preferably has a diameter of 90 to 100 mm on, its length preferably comprises about 1,400 mm.
