Description

Einrichtung zum Schutze der Ausströmelektroden elektrischer Gasreiniger gegen Beschädigung durch Lichtbogenbildung Gegenstand der Erfindung ist eine Einrichtung, die geeignet ist, beim Betrieb von elektrischen Gasreinigern mit Hochspannungsgleichrichtern hoher Leistung die Ausströmelektroden beim Auftreten von Überschlägen zwischen den gegenpoligen Elektroden gegen Abschmelzen zu schützen. Es ist bekannt, zum Schutz der Ausströmelektroden gegen Beschädigung durch Lichtbogen Vorschaltwiderstände in den Hochspannungszuleitungen anzuordnen. Es ist ferner bekannt, diese Vorschaltwiderstände im Innern des Abscheideraumes als Auflager für die Niederschlagelektroden einzubauen.Device to protect the discharge electrodes of electric gas cleaners against damage by arcing The subject of the invention is a device, which is suitable when operating electrical gas cleaners with high-voltage rectifiers high performance the discharge electrodes in the event of flashovers between the to protect opposing polarity electrodes against melting. It is known for protection of the discharge electrodes against damage from arcing series resistors to be arranged in the high-voltage supply lines. It is also known, these ballast resistors to be installed in the interior of the separation room as a support for the precipitation electrodes.

Gemäß der Erfindung wird nur eine Niederschlagelektrode bzw. nur eine Gruppe von Niederschlagelektroden mit einem solchen untergelegten Widerstand ausgerüstet und zugleich das elektrische Feld an dieser Stelle durch geringeren Abstand zwischen den gegenpoligen Elektroden verstärkt. Tritt aus irgendeinem Grunde in dem elektrischen Gasreiniger ein Überschlag auf, so wird der Überschlag an der mit dem untergelegten Widerstand versehenen Niederschlagelektrode oder Elektrodengruppe erfolgen, die einen geringeren Abstand von den Ausströmelektroden als die übrigen Niederschlagelektroden hat. Dieser Überschlag wird durch den vorgeschalteten Widerstand stark gedämpft, und es ergibt sich mit Hilfe eines einzigen Widerstandes, also mit geringen Mitteln, in Verbindung mit der Verringerung des Elektrodenabstandes ein ausreichender Schutz für die ganze elektrische Gasreinigungsanlage.According to the invention, only one precipitation electrode or only one Group of precipitation electrodes equipped with such an underlying resistor and at the same time the electric field at this point due to the smaller distance between the opposing electrodes reinforced. Occurs for some reason in the electric If the gas cleaner has a flashover, the flashover is applied to the one with the one underneath Resistance-provided precipitation electrode or electrode group take place, the a smaller distance from the outflow electrodes than the other precipitation electrodes Has. This flashover is strongly dampened by the upstream resistor, and with the help of a single resistance, i.e. with little means, in connection with the reduction in the distance between the electrodes, adequate protection for the entire electrical gas cleaning system.

An sich ist es bekannt, nur einen einzigen Vorschaltschutzwiderstand zu verwenden bzw. nur einzelne Elektrodengruppen mit einem Schutz dieser Art zu versehen. Bei der bekannten Einrichtung handelt es sich aber nicht um einen solchen Widerstand, der im Innern des Elektrofilters als Unterlage für eine Niederschlagelektrode oder Elektrodengruppe dient, und es fehlt ferner das bei der Erfindung wesentliche Merkmal, daß das elektrische Feld an der Einbaustelle des Widerstandes durch Abstandsverringerung der gegenpoligen Elektroden verstärkt, der einzige Schutzwiderstand also an einer Stelle eingebaut ist, an der die auf ihm abgestützte Niederschlagelektrode einen geringeren Abstand von den Ausströmelektroden hat als die übrigen Niederschlagelektroden des Elektrofilters.It is known per se to have only a single series protection resistor to use or only individual groups of electrodes with a protection of this type Mistake. However, the known device is not one Resistance inside the electrostatic precipitator as a base for a precipitation electrode or electrode group is used, and what is essential in the invention is also lacking Feature that the electric field at the installation point of the resistor by reducing the distance of the electrodes with opposite polarity is reinforced, so the only protective resistance on one Place is installed at which the precipitation electrode supported on it a has a smaller distance from the outflow electrodes than the other precipitation electrodes of the electrostatic precipitator.
