Description

Fangraumelektrocle für Elektrofilter Für Elektrofilter sind Fangraumniederschlagselektroden aus einander profilgleichen Eisen, z. B. gewalzten Doppel-T-Eisen, bekannt, die zu einer großflächigen Elektrode derart aneinandergesetzt werden, daß sie unmittelbar aneinanderstoßen. Derartige Elektroden haben sich gut bewährt. Sobald jedoch große Abmessungen beherrscht werden müssen; wird es schwierig; mit den damit beträchtlich wachsenden; gesteigerten Ge--wichten der bekannten Elektroden dieser Gattung fertig zu werden, da Walzeisen solcher Art sich nicht genügend dünn auswalzen lassen. Außerdem würden die bekannten Walzprofile, auch wenn es _ gelänge, ihre Querschnittsstärke hinreichend zu vermindern, keine Eisen von genügender Knickfestigkeit ergeben.Trap area electrocle for electrostatic precipitators Trap area precipitation electrodes are used for electrostatic precipitators from each other profile iron, z. B. rolled double-T iron, known the be placed together to form a large-area electrode in such a way that they are immediately butt against each other. Such electrodes have proven themselves well. However, once great Dimensions must be mastered; it becomes difficult; with that considerably growing; the increased weights of the known electrodes of this type to become, since these types of iron cannot be rolled out sufficiently thin. aside from that the known rolled sections would, even if they succeeded, reduce their cross-sectional thickness to be reduced sufficiently, no iron of sufficient buckling strength results.

Andererseits hat man den Vorschlag gemacht; Niederschlagsfangraumelektroden aus Blechrinnen herzustellen, die in einem Rahmen in Abständen voneinander befestigt sind. Diese Elektroden haben aber den Nachteil, daß der Gasstrom von der einten Seite der Elektrode in das auf der anderen Seite der Elektrode- befindliche Sprühfeld hindurchtreten kann. Außerdem ist die mechanische Festigkeit solcher Elektroden bei der Verwendung größerer Abmessungen nicht ausreichend, wenn nicht besondere Versteifungen vorgesehen werden. Im folgenden wird nun die Ausbildung einer Fangraumniederschlagselektröde beschrieben, - bei der alle diese Nachteile vermieden werden.On the other hand, the proposal was made; Precipitation trap electrodes made of sheet metal gutters, which are fastened in a frame at a distance from one another are. However, these electrodes have the disadvantage that the gas flow from the one Side of the electrode into the spray field on the other side of the electrode can pass through. In addition, the mechanical strength of such electrodes is when using larger dimensions not sufficient, if not special Stiffeners are provided. In the following, the formation of a trap area precipitation electrode will now be described - in which all these disadvantages are avoided.

Gemäß der Erfindung ist die Fangraumniederschlagselektrod@e in der Weise aus querschnittsgleichen Blechstreifen gebildet, daßder Querschnitt jedes Blechstreifens gleichsam ein in seinen Abbiegungen in stetig,gebogener Kurvenform verlaufendes lateinisches W darstellt, dessen in der Vereinigung stark überhöhte Mittelsclienkel sich im Bereich der Abbiegungen der V-förmigen Hälften des W einander fast berühren und in demselben Bereich auf der mittleren Abbiegung des benachbarten Blechstreifens aufsitzen.According to the invention, the trap chamber precipitation electrode is formed from sheet metal strips with the same cross-section that the cross-section of each sheet metal strip represents, as it were, a Latin W running in its bends in a steady, curved curve shape, the center of which, when combined, is greatly increased in the area of the bends of the V- shaped halves of the W almost touch each other and sit in the same area on the middle bend of the adjacent sheet metal strip.

Eine solche Fangraumnederscblagselektrode hat den großen Vorteil, daß sie ein geringes Gewicht besitzt, da zu ihrer Herstellung ohne weiteres Bleche von sehr geringer Stärke, z. B. o,5 bis i nun, verwendet werden können. Derartige Elektroden besitzen daher nur etwa i/4 bis 1/s des Gewichtes von Fangraumelektroden, die aus Walzprofileisen hergestellt werden. Man kann daher solche Elektroden mit besonderem Vorteil beim Einbau von Filteranlagen in Gebäuden verwenden, deren Grundfläche nur eine verhältnismäßig- geringe spezifische Belastung verträgt. Die Fängraumniederschlagselektrode gemäß der Erfindung besitzt ferner den Vorteil, daß die- Blechstreifen infolge ihres besonderen @W-förinigen Querschnitts ähnlich wie gespundete Bretter .so- aneinandergesetzt werden können, daß ihre Mittelstege zusammenhängende, in der Querrichtung :ui` Gase völlig undurchlässige Fläche bilden.Such a trap area nipple electrode has the great advantage that it has a low weight, since for its production without further sheets of very low strength, e.g. B. o, 5 to i now, can be used. Such Electrodes therefore have only about 1/4 to 1 / s of the weight of trap chamber electrodes, which are made from rolled section iron. You can therefore use such electrodes Particular advantage when installing filter systems in buildings, use their footprint only tolerates a relatively low specific load. The collecting chamber precipitation electrode according to the invention also has the Advantage that the sheet metal strips due to their special @ W-shaped cross-section, similar to pounded boards .So can be put together that their central webs are contiguous, in the transverse direction: ui` gases form a completely impermeable surface.

In der Figur ist ein Ausführungsbeis einer solchen Fangraunmiederschlagselektrode im Querschnitt dargestellt. Die Elektrode besteht, wie die Figur zeigt, aus mehreren dünnen, zu einem W-förmigen Profil gebogenen Blechstreifen, das in seinen. Abbiegungen in stetig gebogener Kurvenform verläuft. Bei seiner Verarbeitung wird jeder Blechstreifen um seine mittlere Längsachse so gebogen, bis, im Querschnitt gesehen, die Enden der beiden so entstandenen- Schenkel fest aneinanderliegen. Die beiden Endstücke 3 und ¢ dieser Schenkel - werden - dann zurückgebogen, bis sie mit den nebeneinanderliegend-en Teilen der Schenkel -je einen -spitzen Winkel von etwa 7o. bis-8o' bilden. Ferner werden die Kanten der Blechstreifen zweckmäßig inngebördelt, damit sie eine bessere mechanische Festigkeit erhalten und nicht sprühen können. Die Abbiegungen der beiden V-förmigen Hälften jedes Blechstreifens bilden alsdann eine Vertiefung, in welche die mittlere Ab-1'egung des benachbarten Blechstreifens hinagt. Derartig geformte Blechstreifen kön-.tti an der Baustelle in beliebiger Zahl zueirier großflächigen Elektrode zusammengesetzt werden.The figure shows an embodiment of such a trap collecting electrode shown in cross section. As the figure shows, the electrode consists of several thin sheet metal strip, bent to a W-shaped profile, which in its. Turns runs in a continuously curved curve shape. Each sheet metal strip is processed during its processing bent about its central longitudinal axis until, seen in cross section, the ends of the two legs created in this way lie firmly against one another. The two end pieces 3 and ¢ of these legs - are - then bent back until they match the adjacent legs Divide the legs into an acute angle of about 7o. to form -8o '. Further the edges of the sheet metal strips are appropriately beaded so that they have a better one Maintain mechanical strength and not be able to spray. The turns of the two V-shaped halves of each sheet metal strip then form a recess into which the middle deposition of the adjacent sheet metal strip protrudes. Such shaped Sheet metal strips can be applied over a large area at the construction site in any number Electrode to be assembled.
