Description

Niederschlagselektrode für elektrische Gasreinigung. Zusatz zum Patent 438 972**). Das Hauptpatent betrifft eine Niederschlagselektrode für elektrische Gasreinigung, die in Form eines schmalen Kastens ausgebildet ist und an den wirksamen Elektrodenflächen mit Schlitzen versehen ist, die ihre freie Durcbgangsöffnung der Gasströmung zukehren. Der abzuscheidende Staub wird daher durch die Schlitzöffnungen in das Innere des Kastens hineingetrieben und gelängt von dort, ohne wieder aufgewirbelt zu werden, in den Bunkerraum. Nach dem Zusatzpatent 447 912 sind die Schlitze winkelförmig, sichelförmig. oder in Form eines liegenden V ausgebildet.Precipitation electrode for electrical gas cleaning. Addendum to Patent 438 972 **). The main patent relates to a collecting electrode for electrical gas cleaning, which is designed in the form of a narrow box and is provided on the effective electrode surfaces with slots, which turn their free passage opening towards the gas flow. The dust to be separated is therefore driven through the slot openings into the interior of the box and from there into the bunker room without being whirled up again. According to the additional patent 447 912, the slots are angular, sickle-shaped. or in the form of a horizontal V.

Es hat sich nun gezeigt, daß bei denjenigen nach dem Hauptpatent oder dem Zusatzpatent ausgebildeten Niederschlagselektroden, die auf beiden wirksamen Seiten des Kastens mit Schlitzen versehen sind, die Gasströmung die Staubteilchen auf der einen Seite zwar in die Schlitze hineintreibt, daß aber bei ungleichmäßiger Druckströmungsverteilung im Gase die Staubteilchen auf der andern Seite dann zum Teil aus dem Innern des Kastens wieder heraustreten. Der Wirkungsgrad der Gasreinigung wird dadurch beeinträchtigt.It has now been shown that those according to the main patent or the additional patent trained collecting electrodes, which are effective on both Sides of the box are slotted, the gas flow the dust particles on the one hand it drifts into the slots, but that when it is more irregular Pressure flow distribution in the gas then leads to the dust particles on the other side Part of the inside of the box step out again. The efficiency of gas cleaning is affected by this.

Um derartige Erscheinungen an Kastenelektroden, die auf beiden Seiten mit Schlitzen versehen sind, zu vermeiden, ist gemäß der vorliegenden Erfindung zwischen den beiden wirksamen Elektrodenflächen im Innern des Kastens eine Trennwand angebracht. Diese Trennwand verhindert ein Wiederaustreten der Staubteilchen aus den Schlitzen, so daß eine wesentlich günstigere Wirkung erzielt wird.To avoid such phenomena on box electrodes on both sides slotted is to be avoided in accordance with the present invention a partition between the two effective electrode surfaces inside the box appropriate. This partition prevents the dust particles from escaping again the slots, so that a much more favorable effect is achieved.

In Abb. i und *'2 !'der Zeichnung ist die neue Anordnung an einem Beispiel veranschaulicht. i und z sind die beiden wirksamen Flächen der kastenförmigen Niederschlagselektrode. Sie sind mit schlitzförmigen öffnungen 3 beiderseits versehen. Die beiden wirksamen Flächen der Elektrode sind im Innern des Kastens durch eine Wand 4 voneinander getrennt.In Fig. I and * '2 !' the drawing illustrates the new arrangement using an example. i and z are the two effective areas of the box-shaped collecting electrode. They are provided with slot-shaped openings 3 on both sides. The two effective surfaces of the electrode are separated from one another by a wall 4 inside the box.
