Description

Vorrichtung zum Abreinigen senkrecht angeordneter Sprühdrähte bei der elektrischen Gasreinigung. Zum Abreinigen von gespannten Sprühdrähten bei der elektrischen Gasreinigung; sind schon zahlreiche Vorschläge gemacht. So gibt es Einrichtungen, bei denen die Elektroden durch irgendwelche Maßnahmen erschüttert oder mittels Abstreifer gereinigt werden, sie haben den Nachteil, daß zu ihrer Bewegung ein mehr oder weniger umfangreicher Mechanismus, der meist sogar noch besonders isoliert werden muß, erforderlich ist. Ein weiterer Vorschlag geht dahin, die Abreinigung durch einen lose um den Sprühdraht gelegten Hilfsdraht zu bewirken; diese Arbeitsweise führt insofern zu Schwierigkeiten, als die Bewegung des hin und her pendelnden Hilfsdrahtes dauernde Feldumbildungen verursacht. -Endlich gibt es Verfahren und Vorrichtungen, bei denen diiq Sprühdrähte durch Ströme von Luft, Gas oder :anderen Medien »abgeblasen« werden. Insbesondere befaßt sich ein Vorschlag damit, Druckluft, die von den Enden der Drähte aus zugeführt wird, an diesen entlang zu blasen. Diese Methode kann wohl Erfolg haben, bei einem trockenen, groben Staub, versagt jedoch vollkommen bei einem zähen, zur Krustenbildung neigenden Niederschlag, wie Hochofengichtstaub. Um die Sprühdrähte von solchem abzureinigen, bedarf eq eines gröberen Mittels.Device for cleaning vertically arranged spray wires at electrical gas cleaning. For cleaning off tensioned spray wires at the electric gas purification; numerous suggestions have already been made. So there is Facilities in which the electrodes are shaken by any measure or cleaned by means of scrapers, they have the disadvantage that they cause movement a more or less extensive mechanism, which is usually even more special must be isolated is required. Another suggestion is the cleaning by an auxiliary wire loosely placed around the spray wire; this way of working leads to difficulties insofar as the movement of the auxiliary wire oscillating back and forth permanent field transformations caused. - Finally there are procedures and devices in which diiq spray wires through currents of air, gas or: others Media are "blown off". In particular, one proposal deals with compressed air, which is fed from the ends of the wires to blow along them. These The method can be successful, but it fails with dry, coarse dust perfect in the case of viscous precipitation tending to form crusts, such as blast furnace gout dust. To clean the spray wires from such, eq requires a coarser means.

Die Erfird:mg bringt nun eine Vorrichtung für senkrecht angeordnete Sprühdrähte, die unter Vermeidung komplizierter Bewegungsmechanismen eine vollkommene Abstreifung auch eines Niederschlags mit großem Haftvermögen gewährleistet.The Erfird: mg now brings a device for vertically arranged Spray wires, which while avoiding complicated movement mechanisms a perfect Stripping off even a precipitate with a high adhesive strength is guaranteed.

Bei dieser Vorrichtung ist erfindungsgemäß jeder Ausströmerdraht mit einem ihn konzentrisch umgebenden beweglichen Körper, 'z. B: einer Kugel, versehen, der durch Druck. Luft oder Preßgas an dem Draht entlang bewegt wird und diesen so in einfacher und sicherer Weise abreinigt. Nebenbei hat diese Anordnung den Vorzug, daß die hochgeschleuderten Abstreifkörper bei Abschaltung des Druckes durch ihr Gewicht beim Herunterfallen das ganze Elektrodensystem erschüttern und auch hierdurch zur Abreinigung beitragen. Eine Ausführungsform der Vorrichtung sei an Hand der Zeichnung, die ein Ausströmersystem darstellt, kurz erläutert. Es sei a der Rahmen, die untere Querverbindung ein Rohr b, in das Preßluft eingeleitet werden kann; c sind die Ausströmer, z. B. dünne Stäbe, deren untere Enden in bekannter Weise durch Löcher oder Düsen d des Rohres b führen. Auf den Löchern oder Düsen lagern auf die Elektrodendrähte aufgestreifte, in deren Längsrichtung bewegliche, zweckmäßigerweise nichtleitende Körper e, z. B. Kugeln oder auf Kugelkalotten aufgesetzte Kegel. Die Wirkungsweise dieser Vorrichtung ist ohne weiteres klar. Durch den in das Rohr b von Zeit zu Zeit eingepreßten Luft- oder Gasstrom werden die Körper e an den Aus.strömern hochgetrieben, der Staub wird dadurch abgestreift, die Körper fallen durch ihre Schwerkraft wieder in ihre Ausgangslage zurück.In this device, according to the invention, each air outlet wire is included a moving body concentrically surrounding it, 'z. B: a ball, provided, the by pressure. Air or compressed gas is moved along the wire and this so cleans in a simple and safe way. Besides, this arrangement has the advantage that the scraper bodies thrown up when the pressure is switched off by her Weight when falling, shake the entire electrode system and thereby cause it to shake contribute to cleaning. An embodiment of the device is based on the Drawing showing an exhaust system briefly explained. Let a frame the lower cross connection a pipe b into which compressed air can be introduced; c are the outlets, e.g. B. thin rods, the lower ends of which in a known manner Guide holes or nozzles d of pipe b. Store on top of the holes or nozzles Electrode wires that are slipped on and are movable in their longitudinal direction, expediently non-conductive bodies e, e.g. B. balls or cones placed on spherical caps. the The operation of this device is readily apparent. Through the in the tube b From time to time injected air or gas flow are the bodies e at the Aus.strömern driven up, the dust is stripped off, the bodies fall through hers Gravity back to its original position.
