Description

Einrichtung für elektrolytische Reinigung von Wasser, insbesondere Speisewasser, für Dampfkessel. Die Erfindung betrifft eine Einrichtung zur elektrolytischen Reinigung von Wasser, insbesondere Speisewasser, für Dampfkessel, bei der die Reinigung in einem Behälter erfolgt, von dem aus das gereinigte Wasser der Verwendungsstelle zugeführt wird. Es, ist dabei nicht nur erwünscht, die eigentlichen Iiesselsteinbildner aus dem zu reinigenden Wasser zu entfernen, sondern es ist wichtig, daß auch andere Gase, insbesondere Sauerstoff, dem zu reinigenden Wasser entzogen werden. Die größte Sauerstoffmenge wird durch die im Wasser befindliche Luft geliefert.Equipment for electrolytic purification of water, in particular Feed water, for steam boilers. The invention relates to a device for electrolytic Purification of water, in particular feed water, for steam boilers, in which the purification takes place in a container, from which the purified water of the point of use is fed. It is not only desirable to be the actual scaler to remove from the water to be purified, but it is important that others also Gases, especially oxygen, are withdrawn from the water to be cleaned. The largest Amount of oxygen is supplied by the air in the water.

Nun hat aber das gereinigte Wasser die Eigenschaft, aus der Umgebung wieder begierig Luft aufzunehmen, so daß schließlich an der Verwendungsstelle erhebliche Sauerstoffmengen wieder indem Wasser vorhanden sind. . Nach der Erfindung wird deshalb der Zutritt von Gasen zu dem gereinigten Wasser verhindert und das Entfernen von Gasen aus dem Wasser, insbesondere das Entfernen der Luft aus dem Wasser, dadurch erreicht, daß die elektrolytisch zu behandelnde Flüssigkeit unter einem Unterdruck gehalten wird. Infolgedessen werden alle aus dem Wasser frei werdenden Gase, insbesondere auch diejenigen, die bei der elektrolytischen Zersetzung entstehen, ständig abgesaugt, und die einmal erreichte Reinheit des Wassers bleibt erhalten. Vor allen Dingen wird vom Wasser die aufgenommene Luft freigegeben und entfernt. Die Einrichtung kann dabei beispielsweise so getroffen werden, daß der Behälter, in dem das Wasser elektrolytisch behandelt wird, luftdicht abgeschlossen ist und an ihm eine Luftpumpe angeschlossen ist, welche ständig ein für die Entfernung der Gasse -erforderliches Vakuum unterhält. Das gereinigte Wasser selbst wird dann in geschlossenen Leitungen der Verwendungsstelle zugeführt.But now the purified water has the property of being from the environment again eager to take in air, so that finally considerable at the point of use Amounts of oxygen again in the presence of water. . According to the invention is therefore prevents the access of gases to the purified water and the removal of Gases from the water, especially removing the air from the water, thereby achieves that the liquid to be electrolytically treated under a negative pressure is held. As a result, all the gases released from the water, in particular also those that arise during electrolytic decomposition are constantly sucked off, and the purity of the water, once achieved, is retained. Above all the air taken in by the water is released and removed. The establishment can for example be made so that the container in which the water Is electrolytically treated, is hermetically sealed and has an air pump on it is connected, which is constantly required for the removal of the alley Vacuum maintains. The purified water itself is then in closed pipes supplied to the point of use.

Gegenüber bekannten Verfahren, bei denen das Speisewasser unter einen Unterdruck gesetzt und frei werdende Gase abgesaugt werden, gelingt es, mit einer Einrichtung nach der Erfindung, auch solche Gase aus, dem Wasser zu entfernen, die bei den bekannten Verfahren nicht entfernt werden können, wie z. B. Kohlensäure, die durch die elektrolytische Behandlung des Wassers überhaupt erst frei wird. Man erhält infolgedessen ein Wasser, das ganz wesentlich weniger aktiv ist als ein Wasser nach den bekannten Verfahren, so daß die Gefahr der Entstehung von Korrosionen erheblich vermindert wird.Compared to known methods in which the feed water under one A vacuum is applied and released gases are sucked out Device according to the invention to remove such gases from the water that can not be removed in the known methods, such. B. carbonic acid, which is only released through the electrolytic treatment of the water. Man As a result, it receives water that is much less active than water according to the known method, so that the risk of corrosion occurring is considerable is decreased.
