Description
Elektrode für elektrische Gasreinigung Bei den bisher bekannten elektrischen Gasreinigungsanlagen muß das auf den Elektroden sich absetzende Niederschlagsgut durch Schüttelvorrichtungen oder andere mechanische Mittel entfernt werden, um den Wirkungsgrad der elektrischen Reinigungskammer nicht zu sehr absinken zu lassen. Solche Reinigungsvorrichtungen sind nur dann zu entbehren, wenn man das elektrische Feld so schwach wählt, daß das Niederschlagsgut nur mit geringer Kraft an die Elektrode angedrückt wird, so daß es von selbst herabfallen kann. Dies ist aber insofern wieder nachteilig, als dadurch der Reinigungsgrad der Kammer stark herabgesetzt wird. Vorliegende Erfindung zeigt nun, wie dieser Nachteil vermieden werden kann.Electrode for electrical gas cleaning In the previously known electrical The precipitate deposited on the electrodes must be used in gas cleaning systems be removed by shaking devices or other mechanical means to remove the Not to let the efficiency of the electric cleaning chamber drop too much. Such cleaning devices can only be dispensed with if you have the electrical Field selects so weak that the precipitate only applies little force to the electrode is pressed so that it can fall down by itself. But this is so again disadvantageous as this greatly reduces the degree of cleaning of the chamber. Present The invention now shows how this disadvantage can be avoided.
Erfindungsgemäß sind die Elektroden mit einer polierten Oberfläche versehen. Dies hat den Vorteil, daß das Niederschlagsgut auch zum Abrutsch kommt, wenn das elektrische Feld in der Niederschlagselektrode stark ist, also der Niederschlag mit ziemlicher Kraft an der Elekttode festgehalten wird. Dadurch nämlich, daß die Oberfläche poliert ist, was auf irgendeine bekannte Weise geschehen kann, wird die durch das Feld bedingte Reibung zwischen Elektrode und Niederschlagsgut von der Schwerkraft überwunden, und der niedergeschlagene Staub fällt von selbst herab.According to the invention, the electrodes have a polished surface Mistake. This has the advantage that the precipitated material also slips off, when the electric field in the collecting electrode is strong, i.e. the precipitation holding on to the electrode with considerable force. Because the The surface is polished, which can be done in some known way becomes the Friction between the electrode and the precipitate caused by the field Overcome gravity, and the precipitated dust falls off by itself.
Im allgemeinen wird man Niederschlags-und Sprühelektroden so polieren, daß das Niederschlagsgut von selbst abrutscht. Es kann aber auch für verschiedene Zwecke vorteilhaft sein, nur eine Elektrode, z. B. die Sprühelektrode, an der sich kein Niederschlag absetzen soll, mit einer glatten Oberfläche zu versehen. Derartige, gemäß der Erfindung polierte Elektroden kann man zweckmäßig aus poliertem Blech oder anderem Metall herstellen. Für verschiedene Zwecke sind aber auch in bekannter Weise aus Halbleitern, wie Marmor oder Gips, bestehende Elektroden geeignet, die erfindungsgemäß mit einer polierten Oberfläche versehen sind.In general, deposition and spray electrodes will be polished in such a way that that the precipitate slips off by itself. But it can also be used for different Purposes may be advantageous to use only one electrode, e.g. B. the spray electrode on which no precipitate should settle, to provide a smooth surface. Such, Electrodes polished according to the invention can advantageously be made from polished sheet metal or other metal. For various purposes, however, are also known Electrodes made of semiconductors such as marble or plaster are suitable for the are provided according to the invention with a polished surface.
Man kann schließlich auch die aus einem Halbleiter bestehenden Elektroden mit einem Stoff überziehen, der polierbar ist, wie z. B. Graphit, und diesen dann polieren. Diese Stoffe können aus Leitern oder Nichtleitern bestehen, je nachdem wie es für den Zweck der Gasreinigungsanlage notwendig ist.Finally, electrodes made of a semiconductor can also be used cover with a substance that can be polished, such as e.g. B. graphite, and then this polishing. These materials can consist of conductors or non-conductors, as the case may be as it is necessary for the purpose of the gas cleaning system.
Man hat zwar auch schon Elektroden mit glatter Oberfläche verwendet, z. B. Drähte oder Stäbe, doch ist die Oberfläche dieser Elektroden nur in dem Sinne glatt, wie es eben bei Körpern, die in üblicher Weise aus den Rohstoffen durch Schmieden, Ziehen usw. hergestellt werden, der Fall ist. An solchen Elektroden setzt sich der Staub fest und muß durch Schüttelung der Elektroden mittels besonderer Vorrichtungen entfernt werden. Wird dagegen die Oberfläche der Elektroden mit besonderen Hilfsmitteln poliert, so kann das unter der Wirkung des elektrischen Feldes sich an ihnen absetzende Niederschlagsgut nicht festhaften, sondern wird von der Schwerkraft ohne weiteres nach unten gezogen. Es besteht dadurch der Vorteil, daß besondere. Schüttelvorrichtungen für die Elektroden erspart werden.Electrodes with a smooth surface have also been used, z. B. wires or rods, but the surface of these electrodes is only in that sense smooth, as is the case with bodies that are usually made from raw materials by forging, Pulling, etc., is the case. The Dust solid and must by shaking the electrodes using special devices removed. On the other hand, the surface of the electrodes is cleaned with special tools polished, it can be deposited on them under the action of the electric field Precipitated material does not adhere, but is easily handled by gravity downward drawn. It has the advantage that special. Shaking devices for the electrodes can be saved.
