Description

Einrichtung zur Erhaltung der Isolation bei elektrischen Gasreinigungsapparaten. Eine beträchtliche Schwierigkeit bei der elektrischen Gasreinigung besteht darin, die Isolatoren und Durchführungen frei von leitenden Überzügen zu erhalten und so die sonst entstehenden Isolationsstörungen zu vermeiden.Device for maintaining the insulation in electrical gas cleaning devices. A significant difficulty with electrical gas cleaning is to keep the insulators and bushings free of conductive coatings and such to avoid the insulation disturbances that otherwise arise.

Die Isolation wird in den praktisch wichtigen Fällen vor allem herabgesetzt durch Wasser, das sich auf den Flächen des Isolators kondensiert. Eine bekannte hIaßregel zur Abhilfe besteht darin, die Isolatoren über den Taupunkt des Rohgases zu erhitzen. Die Isolatorenheizung allein führt aber für viele Staubarten nicht zu befriedigenden Ergebnissen, weil die Staubschichten, die sich auf den Isolationsflächen absetzen, leitend sind und, wenn überhaupt, erst bei zu hohen Tem peraturen nicht leitend werden.The isolation is mainly reduced in the practically important cases by water that condenses on the surfaces of the insulator. An acquaintance The rule of thumb to remedy this is to keep the isolators above the dew point of the raw gas to heat. Insulator heating alone, however, does not lead to many types of dust satisfactory results because of the layers of dust that are on the insulation surfaces stop, are conductive and, if at all, not only when the temperature is too high become a leader.

Die vorliegende Erfindung ergibt einen wirksamen Schutz des Isolators gegen Kondensation von Feuchtigkeit auf seiner Oberfläche und zugleich auch gegen das Beschlagen mit Staub. Dazu wird der Isolator oder die Durchführung in an sich bekannter Weise in einem besonderen Gehäuse aufgestellt, das reit dem Staubraum nur durch eine möglichst enge öffnung, eventuell durch Zwischenstücke oder Rohre (Leitungen), in Verbindung steht. Das Verbindungsstück zwischen Staubraute und Isolatorgehäuse wird derart gekühlt, daß die Feuchtigkeit des Rohgases sich an den geeignet ausgestalteten Wandungen des Zwischenstückes (oder der Öffnung) kondensiert. Unter Umständen kann dabei der Isolator oder das Innere seines Gehäuses geheizt werden.The present invention provides effective protection for the isolator against condensation of moisture on its surface and at the same time against fogging up with dust. This is done by the isolator or the implementation in itself As is known, set up in a special housing that rides the dust room only through an opening that is as narrow as possible, possibly through spacers or pipes (Lines), is in communication. The connecting piece between the dust diamond and the isolator housing is cooled in such a way that the moisture of the raw gas is appropriately configured Walls of the intermediate piece (or the opening) condensed. May be while the insulator or the interior of its housing are heated.

Durch die Kühlung der Gehäuseöffnung des Isolators wird nicht nur der Durchgang vom Dämpfen verhindert oder vermindert. Es tritt dazu noch eine sehr nützliche Nebenerscheinung ein: der Kondensationsvorgang bewirkt nämlich zugleich eine Ausflockung des im Rohgas enthaltenen Staubes. Der ausgeflockte Staub fällt, der Schwere folgend, bei geeigneter Anordnung vom Isolator weg, oder er wird durch Strömungsvorgänge oder aber elektrisch auf den Kühlflächen niedergeschlagen. Das Gehäuseinnere und der Isolator bleiben daher von Staub frei.By cooling the housing opening of the isolator is not only the passage of steaming prevents or diminishes. There is also a very useful by-product: the condensation process causes at the same time a flocculation of the dust contained in the raw gas. The flocculated dust falls following the gravity, with a suitable arrangement away from the isolator, or it will through Flow processes or deposited electrically on the cooling surfaces. That The interior of the housing and the insulator therefore remain free of dust.
