  Einrichtung   zum   elektrischen Schutz der Heizrohre von Kesseln,   Verdampfern u. dgl.   gegen das Ansetzen von Ablagerungen.

 <Desc/Clms Page number 2> 

 Verbindung. Es wird   zweckmässigerweise   ein Stück unter den unteren Rohrboden hinaus verlängert, so dass die Flüssigkeit gezwungen wird, einen längeren Weg zurückzulegen, ehe sie in die Heizrohre wieder eintritt. 



   Bei der Anordnung nach Fig. 3 sind Anode und Kathode nahe aneinandergelegt, indem um die Anode 5 eine besondere, beispielsweise   netzförmig   Kathode 8 gelegt ist. Statt dessen könnten auch plattenförmige Elektroden verwendet werden, zwischen denen die   Flüssigkeit hindurchströmt. Zweck-   mässigerweise wird man auch bei dieser Anordnung den Kessel selbst noch kathodisch anschliessen. 



   PATENT-ANSPRÜCHE :
1. Einrichtung zum elektrischen Schutz   der wirksamen Heizflächen   (d. s. insbesondere die Heizrohre) von Kesseln, Verdampfern od. dgl. gegen das Ansetzen von Ablagerungen, dadurch gekennzeichnet. dass die Anoden und Kathoden in dem zu schützenden Behälter selbst an einer solchen Stelle angeordnet sind, dass die vom Strom durchsetzte Flüssigkeit unmittelbar nach der elektrischen Beeinflussung nur an solche Flächen gelangen kann, an denen Ablagerungen nicht stören.

 Connection. It is expediently extended a little below the lower tube sheet so that the liquid is forced to travel a longer distance before it re-enters the heating tubes.



   In the arrangement according to FIG. 3, the anode and cathode are placed close to one another, in that a special cathode 8, for example in the form of a network, is placed around the anode 5. Instead, plate-shaped electrodes could also be used, between which the liquid flows. With this arrangement, too, the boiler itself will expediently be connected cathodically.



   PATENT CLAIMS:
1. Device for the electrical protection of the effective heating surfaces (i.e., in particular the heating pipes) of boilers, evaporators or the like against the build-up of deposits, characterized in that. that the anodes and cathodes in the container to be protected are themselves arranged at such a point that the liquid through which the current flows can only reach those surfaces immediately after the electrical influence on which deposits do not interfere.

Claims (1)

2. Einrichtung nach Anspruch 1, dadurch gekennzeichnet, dass die Anode gegenüber den Austrittsenden der Heizrohre angeordnet wird. 2. Device according to claim 1, characterized in that the anode is arranged opposite the outlet ends of the heating tubes. 3. Einrichtung nach Anspruch 1, dadurch gekennzeichnet, dass die Anoden in einem Teil des Kessels oder Verdampfers angeordnet sind, in dem der Flüssigkeitsstrom abwärts gerichtet ist. 3. Device according to claim 1, characterized in that the anodes are arranged in a part of the boiler or evaporator in which the liquid flow is directed downwards. 4. Einrichtung nach Anspruch 1 bei Verdampfern, dadurch gekennzeichnet, dass zwischen den Heizrohren ein Fallrohr von grösserem Durchmesser als die Heizrohre angeordnet ist, in dessen Innern die Anode liegt. 4. Device according to claim 1 in the case of evaporators, characterized in that a downpipe of larger diameter than the heating pipes is arranged between the heating pipes, inside which the anode is located. 5. Einrichtung nach Anspruch 1 und 4, dadurch gekennzeichnet, dass das Fallrohr als Kathode dient. 5. Device according to claim 1 and 4, characterized in that the downpipe serves as a cathode. 6. Einrichtung nach Anspruch 1 und 4, dadurch gekennzeichnet, dass das Fallrohr nach unten über die Heizrohre hinaus verlängert ist. EMI2.1 6. Device according to claim 1 and 4, characterized in that the downpipe is extended downward beyond the heating pipes. EMI2.1
