Description

Isolierkörper für Elektrodendampferzeuger Bei der Verwendung von hochgespannten Wechselströmen für die Dampferzeugung in Dampfkesseln, die nach dem Elektrodenprinzip arbeiten, sind in diese Kessel bekanntlich Isolierkörper einzubauen, um den Weg des elektrischen Stromes in der Widerstandsflüssigkeit zu vergrößern und dadurch die gewünschte Leistung zu erhalten. Diese Isolierkörper sind bis jetzt vorzugsweise aus Quarz hergestellt worden. Quarz bietet den Vorteil, daß es unempfindlich gegen rasche Temperaturwechsel ist. Dagegen weist es den Nachteil auf, daß es selbst von nur schwach alkalischem Speisewasser verhältnismäßig rasch zerstört wird. Dies ist ein um so schwerwiegenderer Nachteil, als derartige Isolierkörper teuer sind und eine Zerstörung derselben sehr unangenehme Betriebsstörungen bedingt.Insulating body for electrode steam generator When using high voltage Alternating currents for steam generation in steam boilers, based on the electrode principle work, insulators are known to be built into these boilers to avoid the path of the electric current in the resistance fluid and thereby to get the performance you want. These insulating bodies have been preferred up to now made of quartz. Quartz has the advantage that it is insensitive to rapid temperature change is. On the other hand, it has the disadvantage that it is itself of only weakly alkaline feed water is destroyed relatively quickly. This is a disadvantage that is all the more serious as such insulating bodies are expensive and destruction of the same causes very unpleasant operational disruptions.

Zwecks Behebung dieser üb.elstände ist nun der vorliegende Isolierkörper erfindungsgemäß mit einem Anstrich aus Zementmilch, d. b. aus in Wasser gelöstem reinem Zement, versehen.The present insulating body is now used to remedy these deficiencies according to the invention with a paint made from cement milk, d. b. from dissolved in water pure cement.

Während die bisherigen Versuche, durch Anstrich mit Farbe oder farbeähnlichen Produkten die schädlichen Einwirkungen des Stromes auf metallene Teile von Elektrokesseln, z. B. auf deren Wandungen, zu verhindern, sich als gänzlich ungeeignet erwiesen, da diese Anstriche den im Wasser auftretenden Spannungen nicht gewachsen waren, werden die hier in Frage kommenden Isolierkörper, die außer aus Quarz auch aus Schamotte oder einem ähnlichen gegen Temperaturschwankungen widerstandsfähigen Material bestehen können, durch einen Anstrich aus Zementmilch vor den Angriffen des Wassers sehr wirksam geschützt. Gegenüber Massen, wie sie als stärkerer Auftrag zum Schutze der Wände von Elektrokesseln gegen die zerstörende Wirkung des elektrischen Stromes und gegen elektrolytische Vorgänge verwendet werden und welche Massen aus eitler Zusammensetzung aus isolierenden Körpern mit einem im Wasser abbindenden Bindemittel bestehen, stellt ein Anstrich, bestehend nur aus Zementmilch, eine wesentliche Vereinfachung und Verbilligung dar.While the previous attempts, by painting with paint or color-like Products the harmful effects of electricity on metal parts of electric boilers, z. B. on their walls, to prevent, proved to be completely unsuitable, as these paints were not able to withstand the stresses occurring in the water, are the insulating bodies in question here, which are made of chamotte in addition to quartz or a similar material that is resistant to temperature fluctuations can protect against the attacks of the water by a coat of cement milk effectively protected. Towards the masses, as they are more strongly mandated to protect the Walls of electric boilers against the destructive effects of the electric current and used against electrolytic processes and what masses from vain Composition of insulating bodies with a binding agent that sets in water paint consisting only of cement milk represents a significant simplification and cheaper.

Vielfach dürfte es nicht erforderlich sein, sämtliche Flächen des Isolierkörpers mit einem Anstrich aus Zementmilch zu versehen, sondern schon genügen, wenn nur die am meisten gefährdeten Flächen, welches immer die den Elektroden zugekehrten Flächen sind, mit dem Anstrich versehen sind.In many cases it should not be necessary to cover all areas of the To provide the insulating body with a coat of cement milk, it is enough to if only the most endangered areas, whichever is the one facing the electrodes Are surfaces that have been painted.
