Description

Einrichtung zur elektrischen Ausscheidung von Schwebekörpern aus elektrisch isolierenden, insbesondere gasförmigen lnedien. Bei der elektrischen Abscheidung und Niederschlagung von Schwebekörpern aus elektrisch isolierenden, insbesondere gasförmigen Medien mit Hilfe von Elektrizitätsausströmern (Sprühelektroden) und gegenpoligen Niederschlagselektroden hat man schon vorgeschlagen, die Elektroden in Gruppen anzuordnen und die einzelnen aufeinanderfolgenden Abschnitte derart verschieden voneinander elektrisch einzustellen, daß mit zunehmender Reinheit des Mediums eine stufenweise gesteigerte, von den Sprühelektroden ausgehende Stromdichte auftritt. Es hat sich gezeigt, daß trotz dieser stufenweisen Steigerung der Stromdichte namentlich feinere Schwebeteilchen urabgeschieden bleiben können. Die Erfindung beruht nun auf der Erkenntnis, daß diesem Mangel abgeholfen wird, wenn die Stromdichte in unmittelbarer Nähe der Niederschlagselektrode gegenüber der mittleren Stromdichte in dem betreffenden Behandlungsabschnitt erhöht wird. Aus dieser Erhöhung der Stromdichte in nächster Nachbarschaft der Niederschlagselektrode ergibt sich eine wesentliche Verbesserung der Abscheidung. Erreicht wird diese besondere Art der Steigerung der Stromdichte 'dadurch, daß die Niederschlagselektrode und die Sprühelektrode mit Bezug auf ihre gegenseitige Gestaltung und Anordnung in den einzelnen Behandlungsabschnitten verschieden ausgeführt werden.Device for the electrical elimination of floating bodies from electrical insulating, especially gaseous, media. In the case of electrical deposition and precipitation of floating bodies from electrically insulating, in particular gaseous media with the help of electricity vents (spray electrodes) and Opposite polarity precipitation electrodes have already been proposed, the electrodes to be arranged in groups and the individual successive sections so different from each other electrically adjust that with increasing purity of the medium one step-by-step increased current density emanating from the spray electrodes occurs. It has been shown that in spite of this step-by-step increase in the current density in particular finer suspended particles can remain separated. The invention is now based on the knowledge that this deficiency is remedied if the current density is in the immediate Proximity of the collecting electrode compared to the mean current density in the relevant one Treatment section is increased. From this increase in current density in the next There is a significant improvement in the vicinity of the collecting electrode the deposition. This special type of increase in current density is achieved 'in that the collecting electrode and the spray electrode with respect to their mutual design and arrangement in the individual treatment sections different are executed.

Eine Möglichkeit zur Ausführung der Erfindung besteht darin, daß in den nachfolgen-; den Behandlungsabschnitten die Querschnitte der plattenförmigen Niederschlagselektroden gekrümmt, z. B. oval, gewählt werden. Dadurch erreicht man eine Verringerung des Abstandes zwischen Niederschlagsfläche und Sprühelektrode, und zwar insbesondere an der Stelle der Krümmung, und im allgemeinen eine erhöhte Stromdichte an der Niederschlagsfläche.One way to carry out the invention is that in the subsequent; the treatment sections the cross-sections of the plate-shaped Curved collecting electrodes, e.g. B. oval, can be selected. This is how you achieve a reduction in the distance between the precipitation surface and the spray electrode, in particular at the point of curvature, and generally an increased one Current density on the precipitation surface.
