Description

Aus einem Halbleiter bestehende Niederschlagselektrode für die elektrische Reinigung von Gasen Es ist bereits bekannt, die Niederschlagselektroden für die elektrische Reinigung von Gasen aus einem Halbleiter herzustellen, indem man z. B. Ton- oder Zementrohre bzw. Platten für die Elektroden verwendet. Derartige Elektroden haben den Vorteil, daß sie gegenüber ätzenden Gasen oder Dämpfen sehr widerstandsfähig sind, wobei ihre Leitfähigkeit für die Zuführung des elektrischen Stromes noch ausreicht. Ein Nachteil dieser Elektroden besteht aber in ihrer geringen Widerstandsfähigkeit gegen mechanische Erschütterungen. Sie zerbrechen leicht, bekommen Risse und können dann zu sehr störenden Betriebsunterbrechungen Veranlassung geben.Precipitation electrode consisting of a semiconductor for the electrical Purification of gases It is already known to use the collecting electrodes for the to produce electrical purification of gases from a semiconductor by z. B. clay or cement pipes or plates are used for the electrodes. Such electrodes have the advantage that they are very resistant to corrosive gases or vapors are, where their conductivity is still sufficient for the supply of electrical current. However, a disadvantage of these electrodes is their low resistance against mechanical vibrations. They break easily, crack, and can then give rise to very disruptive business interruptions.

Nach der Erfindung werden nun derartige Niederschlagselektroden für die Erzielung der nötigen Stoßfestigkeit ausAsbestschiefer, Asbestzement, einer anderen Asbestmischung oder überhaupt aus einer Mischung von einem Bindemittel, wie z. B. Gips oder Zement, mit einem Fasermaterial, wie z. B. Asbest, Schlackenwolle, Haaren oder Holzfasern, hergestellt. Der Asbestschiefer wird bekanntlich derart hergestellt, daß Asbest unter Beimengung eines Bindemittels zu Platten gepreßt wird. Derartige Elektroden sind einerseits ebenso widerstandsfähig wie die bisher verwendeten gegen ätzende Dämpfe, andererseits halten sie aber weit besser Erschütterungen aus. Sie lassen sich außerdem leicht sägen oder auf ähnliche Weise in beliebige Form bringen, ohne zu zerspringen. Ebenso können sie leicht z. B. durch Nageln befestigt werden.According to the invention, such collecting electrodes are now for the achievement of the necessary shock resistance from asbestos slate, asbestos cement, one other asbestos mixture or any mixture of a binding agent, such as B. plaster of paris or cement, with a fiber material such. B. asbestos, slag wool, Hair or wood fiber. The asbestos slate is known to be like this produced that asbestos is pressed into panels with the addition of a binder. Such electrodes are on the one hand just as resistant as those previously used against corrosive vapors, but on the other hand they withstand vibrations much better. They can also be easily sawed or similarly cut into any shape without bursting. You can also easily z. B. fastened by nailing will.

Um die Leitfähigkeit der Elektroden nach der Erfindung zu erhöhen, kann man sie mit einem Zusatz von Graphit, Kohlepulver, Metall- oder Metalloxydpulvern oder sonstigen leitenden Metallverbindungen zu dem Material der Elektrode versehen.In order to increase the conductivity of the electrodes according to the invention, you can add graphite, carbon powder, metal or metal oxide powders or other conductive metal connections to the material of the electrode.
