Description
Die Erfindung betrifft eine Wasserbehandlungseinrichtung mit einem Gehäuse, das einen Wasserzulauf und einen Wasserablauf aufweist, wobei in dem Gehäuse eine Opferanoden-Einrichtung untergebracht ist.The The invention relates to a water treatment device with a housing, the having a water inlet and a water outlet, wherein in the casing a sacrificial anode device is housed.
Solche Wasserbehandlungseinrichtungen werden zur Verminderung von Korrosionserscheinungen in wasserführenden Anlagen eingesetzt. Dabei wird unter Ausnützung des elektrolytischen Prozesses die deckschichtbildende Eigenschaft des Wassers unterstützt. Hierzu ist in der Wasserbehandlungseinrichtung eine Magnesiumanode eingesetzt, die sich während der Behandlungszeit opfert. Dabei werden metallische Magnesiumpartikel, sogenannte Magnesium-Kolloide, aus der Magnesiumanode herausgelöst. Diese werden mit dem strömenden Wasser abtransportiert und lagern sich an den metallischen Wandungen der zu schützenden wasserführenden Leitungsbereiche lokal ab. Dort bilden sie aufgrund ihres elektrochemisch unedlen Charakters eine Nanoanode und schützen so den umgebenden Leitungsbereich.Such Water treatment facilities are used to reduce corrosion in water-bearing Equipment used. It is under utilization of the electrolytic Process supports the capping property of the water. For this is used in the water treatment device, a magnesium anode, the while sacrifices the treatment time. This involves metallic magnesium particles, so-called magnesium colloids, extracted from the magnesium anode. These be with the pouring Transported water and store on the metallic walls the one to be protected water-bearing Management areas locally. There they form due to their electrochemical a feathered nano anode, thus protecting the surrounding conduction area.
Bei den bekannten, auf diesem Wirkprinzip arbeitenden Wasserbehandlungseinrichtungen wird der erforderliche großvolumige Aufbau als störend empfunden. Um eine wirkungsvolle Behandlung auch bei größeren Volumenströmen zu garantieren, muss eine entsprechende Anodengröße vorgesehen sein, was jedoch dann auch eine entsprechende Gestaltung der Kathode erfordert.at the well-known, working on this principle water treatment facilities becomes the required large volume Construction perceived as disturbing. In order to guarantee an effective treatment even with larger volume flows, must a corresponding anode size be provided But what then also requires a corresponding design of the cathode.
Es ist Aufgabe der Erfindung, eine Wasserbehandlungseinrichtung der eingangs erwähnten Art zu schaffen, die einen leistungsfähigen Korrosionsschutz auf kleinem Bauraum ermöglicht.It Object of the invention, a water treatment device of mentioned in the beginning Kind of creating a powerful anti-corrosion protection small space allows.
Diese Aufgabe wird dadurch gelöst, dass in dem Gehäuse wenigstens zwei Elektroden, bestehend aus einem Opferanoden-Material und mit unterschiedlicher Polung, untergebracht sind, dass diese Elektroden im wasserdurchströmten Gehäusebereich angeordnet sind, und dass die Elektroden mittels einer Steuereinrichtung im Laufe der Wasserbehandlungsdauer umpolbar sind. Bei dieser Anordnung wird das Elektrodenopfermaterial sowohl an der Anode als auch an der Kathode verwendet. Infolge der Umpolvorgänge werden die beiden Elektroden abgebaut und tragen so zum Korrosionsschutz bei. Auf diese Weise kann auf engem Raum eine große Menge an reaktivem Material untergebracht werden.These Task is solved by that in the case at least two electrodes consisting of a sacrificial anode material and with different polarity, are accommodated that these electrodes in the water flowing through housing area are arranged, and that the electrodes by means of a control device be repolished during the water treatment period. In this arrangement becomes the electrode sacrificial material both at the anode and on the cathode used. As a result of Umpolvorgänge the two electrodes are degraded and thus contribute to corrosion protection. That way you can up a large amount of space be housed on reactive material.
Vorzugsweise wird für die Elektroden Magnesium eingesetzt, das aufgrund Hygiene- und Gesundheitsanforderungen in reiner Form vorliegen soll.Preferably is for The electrodes used magnesium due to hygiene and health requirements should be in pure form.
Gemäß einer bevorzugten Ausgestaltung der Erfindung ist eine besonders effektive Wasserbehandlung dann möglich, wenn vorgesehen ist, dass beide Elektroden aus Magnesium und/oder Zink bestehen.According to one preferred embodiment of the invention is a particularly effective Water treatment then possible if it is provided that both electrodes of magnesium and / or Zinc exist.
Um einen gleichmäßigen Behandlungserfolg in den einzelnen Polungsphasen zu erreichen, kann es vorgesehen sein, dass in dem Gehäuse vier Elektroden untergebracht sind, die paarweise über Kreuz kontaktiert sind.Around a uniform treatment success in to reach the individual poling phases, it can be provided that in the case four electrodes are accommodated, which contacts in pairs crosswise are.
Ein gleichmäßiger Abtrag der Elektroden wird auf einfache Weise dadurch möglich, dass die benachbarten Elektroden äquidistant zueinander angeordnet sind. Wenn die Elektroden dabei baugleich sind, wird eine gleichmäßige Lebensdauer erreicht.One even removal the electrodes is possible in a simple manner that the adjacent Electrodes equidistant are arranged to each other. If the electrodes are identical, becomes a uniform life reached.
Ein gleichmäßiger Abbau des Anodenmaterials lässt sich exakt dadurch steuern, dass der Wechsel von Anoden- auf Kathodenschaltung der Elektroden periodisch erfolgt und/oder dass der Wechsel von Anoden- auf Kathodenschaltung der Elektroden in Abhängigkeit von einer vorgegebenen Ladungsmenge erfolgt.One even degradation of the anode material Control exactly by switching from anode to cathode the electrodes are periodically and / or that the change of Anode to cathode switching of the electrodes in dependence from a given amount of charge.
Für die Wasserbehandlungseinrichtung ergibt sich dann ein kompakter Aufbau, wenn vorgesehen ist, dass die Elektroden in einem Behandlungsraum angeordnet sind, der von einer wasserdurchlässigen Wandung im Behandlungsraum eine Leitung angeordnet ist, die in wasserleitender Verbindung mit dem Behandlungsraum steht und dass die Wandung unter Belassung eines Wasserströmungsbereiches von dem Gehäuse wasserdicht umgeben ist. Dabei kann das zu behandelnde Wasser durch die Wandung in den Behandlungsraum einströmen und diesen dann wieder durch die Leitung verlassen. Denkbar ist auch eine Verwendung der Wasserbehandlungseinrichtung in umgekehrter Strömungsrichtung. Ein effektiver Kurzschlussschutz kann auf einfache Weise dadurch erreicht werden, dass die Elektroden mittels wasserdurchlässigen Schottwänden voneinander getrennt sind.For the water treatment device then results in a compact structure, if it is provided that the electrodes are arranged in a treatment room, the of a water-permeable Wall in the treatment room a pipe is arranged, which in water-conducting Connection with the treatment room stands and that the wall under Leaving a water flow area from the case is surrounded watertight. Here, the water to be treated by the Wall flow into the treatment room and this again leave through the line. It is also conceivable use of the Water treatment device in the reverse flow direction. An effective one Short circuit protection can be easily achieved by that the electrodes by means of water-permeable bulkheads from each other are separated.
Den Schottwänden kann eine weitere funktionelle Eigenschaft zugeordnet werden, wenn vorgesehen ist, dass die Schottwände die wasserdurchlässige Wandung gegenüber der im Behandlungsraum angeordneten Leitung abstützen. Dann kann die wasserdurchlässige Wandung mit hoher Durchlässigkeit materialoptimiert ausgeführt werden.The bulkheads can be assigned another functional property if provided is that the bulkheads the water permeable Wall opposite supported by the arranged in the treatment room line. Then the water-permeable wall can with high permeability material optimized executed become.
Gemäß einer bevorzugten Erfindungsausgestaltung kann es vorgesehen sein, dass einer Steuereinrichtung ein Strömungsmesser zugeordnet ist, der den Volumenstrom des Wassers misst und den Messwert der Steuereinrichtung übermittelt und dass die Steuereinrichtung den Elektrolysestrom in Abhängigkeit vom Volumenstrom regelt.According to one preferred embodiment of the invention may be provided that a control device, a flow meter is assigned, which measures the volume flow of the water and the measured value the control device transmitted and that the control means the electrolysis current in dependence regulated by the flow rate.
Auf diese Weise wird die Behandlungsintensität auf das Wasserentnahmevolumen angepasst. Dadurch kann auch die Lebensdauer der Elektroden optimiert werden.On this way, the treatment intensity on the water withdrawal volume customized. This can also optimize the life of the electrodes become.
Gemäß einer bevorzugten Ausgestaltungsvariante der Erfindung ist es vorgesehen, dass jeder der beiden materialgleichen Elektroden jeweils eine Elektrode eines anderen Materiales zugeordnet ist, mit der sie über eine Kurzschlussverbindung galvanisch gekoppelt ist. Mit dieser Anordnung kann der Aufbau vereinfacht werden, so dass eine kostengünstige außenstromlose Lösung entsteht.According to one preferred embodiment variant of the invention it is provided each of the two material-like electrodes has one electrode each associated with another material with which it has a Short circuit connection is galvanically coupled. With this arrangement The structure can be simplified, so that a cost-effective without external power solution arises.
Wenn bei einer erfindungsgemäßen Wasserbehandlungseinrichtung zusätzlich vorgesehen ist, dass die Elektroden im Behandlungsraum in Elektrodenräumen angeordnet sind, dass in dem Behandlungsraum räumlich getrennt von den Elektrodenräumen wenigstens eine Festbettelektrode untergebracht ist, die zumindest an einem Teil des zu behandelnden Wassers durchströmt ist, dann wird zusätzlich ein wirkungsvoller Verkalkungsschutz geschaffen. Dabei macht man sich die Erkenntnis zunutze, dass sich das im Wasser ebenfalls befindliche Calcium als Calcit an den negativen Polbereichen der Festbettelektrode ablagert. Die dauerhafte Calcit-Ablagerung wird durch die Umpolung verhindert. Nach dem Umpolvorgang wird das Calcit abgesprengt und mit dem fließenden Wasser abgeführt. Damit ist ein Verkalken des nachfolgenden Leitungsnetzes verhindert.If in a water treatment device according to the invention additionally it is provided that the electrodes are arranged in the treatment space in electrode spaces are that in the treatment room spatially separated from the electrode spaces at least a fixed bed electrode is housed, at least at one Part of the water to be treated is flowed through, then an additional created effective calcification protection. You do it yourself use the knowledge that this is also in the water Calcium as calcite at the negative pole regions of the fixed-bed electrode deposits. The permanent calcite deposit is prevented by the polarity reversal. After Umpolvorgang is the Calcite blasted and discharged with the flowing water. In order to is a calcification of the subsequent pipeline network prevented.
Die Festbettelektrode kann dabei als bipolare Elektrode entweder aus elektrisch leitenden oder leitenden oder nicht leitenden Partikeln in gleichmäßiger Mischung verwendet sein.The Fixed bed electrode can be used as a bipolar electrode either electrically conductive or conductive or non-conductive particles in a uniform mixture be used.
Bevorzugter Weise ist jedoch vorgesehen, dass die Festbettelektrode von einer Schüttung aus elektrisch leitfähigem Material besteht. Dieses wird von einem einheitlichen Granulat, beispielsweise von einer Kohleschüttung, gebildet. Durch diese Schüttung kann das Wasser während der Behandlung strömen. Die Schüttung bildet große reaktive Oberflächen, so dass eine wirksame Kalkschutzfunktion möglich wird.preferred However, it is provided that the fixed bed electrode of a fill made of electrically conductive Material exists. This is made of a uniform granulate, For example, from a coal bed formed. Through this fill can the water while to pour the treatment. The bed makes big ones reactive surfaces, so that an effective Kalkschutzfunktion is possible.
