Description

Aus einem Halbleiter bestehende Niederschlagselektrode für elektrische Gasreiniger Die Niederschlagselektroden -für Elektrofilter werden vielfach aus Halbleitern,- z. B. Holz, Papier, Zement, Beton usw., hergestellt, weil derartige Elektroden für manche Zwecke gewisse Vorzüge besitzen. Z. B. kann bei derartigen Elektroden eine Funkenentladung kaum eintreten, weil durch den Halbleiter der Übergang des Stromes sehr stark begrenzt wird. Man kann deshalb eine verhältnismäßig hohe Spannung an solche Elektrofilter legen und auf diese Weise eine besonders gute Niederschlagswirkung erzielen. Im folgenden wird nun eine besondere Ausbildung einer derartigen Niederschlagselektrode gezeigt; welche eine günstige Aufhängung derselben ermöglicht.Precipitation electrode consisting of a semiconductor for electrical Gas purifier The precipitation electrodes - for electrostatic precipitators are often made of semiconductors, z. B. wood, paper, cement, concrete, etc., made because such electrodes for some purposes have certain merits. For example, with such electrodes a Spark discharge hardly ever occurs because the current is passed through the semiconductor is very limited. You can therefore apply a relatively high voltage place such electrostatic precipitators and in this way a particularly good precipitation effect achieve. A special design of such a collecting electrode will now be described below shown; which allows a convenient suspension of the same.

Gemäß der Erfindung wird die aus einem Halbleiter bestehende Niederschlagselektrode in der Weise ausgebildet, daß sie aus zwei in geringemAbstandevoneinander angeordneten, vorteilhaft armierten Halbleiterplatten zusammengesetzt ist, zwischen denen die Aufhängevorrichtungen der Elektrode angebracht sind. Hierdurch wird der Vorteil erreicht, daß die Gleichmäßigkeit des Sprühfeldes zwischen den Sprüh-und Niederschlagselektroden in vollkommener Weise gewährleistet wird. Bisher waren nämlich meist die Trageisen auf den Flächen der Niederschlagselektrode angeordnet, die den Sprühelektroden zugewendet sind. Es besteht dann die Gefahr, daß sich ein Sprühstrom von den Trageisen nach den Sprühelektroden hin ausbildet und womöglich Funkenüberschläge zwischen beiden Teilen stattfinden. Dieser Übelstand ist nun durch die angegebene Ausbildungsform der Niederschlagselektrode gänzlich beseitigt. Die Aufhängevorrichtung ist dann durch die Halbleiterplatten wirksam gegen die Sprühplatte abgeblendet. -In den Fig. x und 2 ist ein Ausführungsbeispiel einer in dieser Weise ausgebildeten Niederschlagselektrode im Auf- und Seitenriß dargestellt. io und ii sind zwei aus einem Halbleiter bestehende Platten, die durch die Bolzen 12 miteinander verbunden und in einem gewissen Äbstande voneinander gehalten sind. Auf die beiden einander abgewendeten Seiten der Halbleiterplatten io und ii sind zur Armierung derselben als Fangrinnen ausgebildete Eisen 13 aufgelegt und gleichfalls durch die Bolzen 12 befestigt. DerAbstand der beiden Platten io und ii ist so groß gewählt, daß die zur Aufhängung der Niederschlagselektrode dienenden Trageisen in dem Zwischenraum Platz haben und dort an den Bolzen 12 befestigt sind.According to the invention, the precipitation electrode made of a semiconductor designed in such a way that it consists of two advantageously reinforced semiconductor plates is composed, between which the Suspension devices of the electrode are attached. This creates the advantage achieves that the uniformity of the spray field between the spray and collecting electrodes is guaranteed in a perfect way. Up until now, it was mostly the carrying irons arranged on the surfaces of the collecting electrode facing the spray electrodes are. There is then the risk that a spray stream from the carrying irons will follow the spray electrodes and possibly arcing between the two Sharing take place. This disadvantage is now due to the specified form of training the collecting electrode completely eliminated. The hanger is then effectively shielded from the spray plate by the semiconductor plates. -In the Fig. x and 2 is an exemplary embodiment of a collecting electrode designed in this way Shown in front and side elevation. io and ii are two made of one semiconductor Plates connected to each other by bolts 12 and spaced at a certain distance are held from each other. On the two opposite sides of the semiconductor plates io and ii are laid iron 13 designed as guttering to reinforce the same and also fastened by the bolts 12. The distance between the two plates io and ii is chosen to be so large that those used to suspend the collecting electrode Carrying irons have space in the space and are attached to the bolts 12 there.
