Description

Niederschlagselektrode für die elektrische Gasreinigung. Für die elektrische Reinigung von Gasen oder Dämpfen ist es bereits bekannt, Niederschlagselektroden in Form von Wellblechen zu verwenden. Diese Wellblechelektroden haben sich auch für das Absetzen des Staubes als günstig erwiesen. Der Staub setzt sich aber dabei vorwiegend innerhalb der einzelnen Rillen der Elektrode ab, so daß, wie die Erfahrung gezeigt hat, das Wellblech dadurch zum großen Teil in seiner Wirkung als Gegenelektrode zu den Sprühelektroden beeinträchtigt wird.Precipitation electrode for electrical gas cleaning. For the electric Cleaning of gases or vapors is already known, collecting electrodes to be used in the form of corrugated sheets. These corrugated iron electrodes have become too Proven to be beneficial for the settling of the dust. But the dust settles in the process mainly within the individual grooves of the electrode, so that, as the experience has shown that the corrugated iron largely acts as a counter electrode to the spray electrodes is affected.

Lm dies zu vermeiden, wird erfindungse m# äß die Wel' ib lechelektrode auf einer oder auf beiden Seiten mit einem Drahtnetz abgedeckt. Infolge dieser Abdeckung geht das elektrische Feld nunmehr nicht mehr vom Wellblech, sondern zum größten Teil vom Drahtnetz aus. Das Drahtnetz kann aber durch den sich abscheidenden Staub nicht mit einer so starken Schutzschicht wie die Rillen des Wellbleches bedeckt werden. Die Abscheidewirktrng einer derartigen Elektrode wird daher bedeutend gleichmäßiger sein als bei der Verwendung des einfachen Wellbleches.In order to avoid this, the invention is based on the Wel 'ib Iech electrode covered on one or both sides with a wire mesh. As a result of this coverage the electric field no longer goes from the corrugated iron, but to the largest one Part of the wire mesh. The wire mesh can, however, through the separating dust not covered with such a strong protective layer as the grooves of the corrugated sheet metal will. The deposition effect of such an electrode is therefore significantly more uniform than when using the simple corrugated sheet.

Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung. Zu beiden Seiten der netzartigen Sprühelektrode i sind in Richtung des Gasstromes zwei als Niederschlagselektrode dienende Wellbleche-- und 3 angeordniet. Die Rillen des Wellbleches verlaufen in senkrechter Richtung. Die beiden Wellbleche sind nun auf beiden Seiten mit einem Drahtnetz 4. abgedeckt. Dieses Drahtnetz ist als ein endloses bewegliches Band ausgebildet, das über die Rollen 6 und 7 geführt wird. Die Anordnung der beiden Drahtnetze als endloses Band gestattet eine leichte Abreinigung der Netze. Es sind hierfür zwei ruhende Bürsten ä und y vorgesehen, die den Staub von dem vorbeilaufenden Drahtnetz abstreifen. Das Drahtnetz wird daher nach außen ständig blank bleiben, so daß das elektrische Feld immer in der gewünschten Art sich ausbilden kann.The drawing shows an embodiment of the invention. To both Sides of the net-like spray electrode i are two as in the direction of the gas flow Corrugated sheets used for collecting electrodes - and 3 arranged. The grooves of the corrugated sheet run in a vertical direction. The two corrugated sheets are now on both sides covered with a wire mesh 4.. This wire network is as an endless moving one Band formed, which is guided over the rollers 6 and 7. The arrangement of the two Wire nets as an endless belt allow easy cleaning of the nets. There are two stationary brushes ä and y are provided for this purpose, which remove the dust from the passing Strip off the wire mesh. The wire mesh will therefore always remain bare to the outside, so that the electric field can always develop in the desired way.
