Description

Vorrichtung zum Schutze der Isolatoren elektrischer Gasreiniger Durch Ablagerung von Verunreinigungen aus dem staubführenden Gas treten bekanntlich bei elektrischen Gasreinigungsanlagen sehr häufig Isolationsstörungen ein, welche den Betrieb der Anlage in Frage stellen können und deshalb Maßnahmen zu ihrer Verhütung bzw. möglichst schnellen Beseitigung erfordern.Device to protect the insulators of electric gas purifiers It is known that deposits of impurities from the dust-carrying gas occur electrical gas cleaning systems very often insulation faults, which the Can jeopardize the operation of the system and therefore take measures to prevent it or require removal as quickly as possible.

Es sind bereits verschiedene Verfahren biekannt, die diesem Übelstand abhelfen sollen; insbesondere hat man die Isolatoren in besonderen Räiunen untergebracht, um sie dem Zutritt des verunreinigten Gases möglichst zu entziehen. Man hat diese Räume weiterhin durch elektrische Felder gegen den Gasraum hin ,abzuschirmen versucht und ,ähnliches mehr.Various methods are already known to address this problem to remedy; in particular, the isolators were placed in special rooms, in order to remove them as far as possible from the ingress of the contaminated gas. You have this Attempts to shield the room further against the gas space by means of electric fields and more like that.

Bekannt ist auch das Verfahren, die Oberfläche der Isolatoren dadurch sauber zu halten, daß man einen Strom reinen Gases über den Isolator hinwegleitet, um dadurch die Verunreinigung der Oberfläche zu vermeiden oder abgelagerten Staub, zu entfernen.The process is also known, the surface of the insulators thereby keep clean by passing a stream of pure gas over the insulator, in order to avoid the contamination of the surface or deposited dust, to remove.

Die nachstehend beschriebene Erfindung gibt eine Vorrichtung an, um die Isolatoren gegen Staubablagerungen zu schützen, und zwar wird ein Strom reinen Gases durch die Hochspannungsleitung 'selbst in das Kammerinnere geführt und in der Nähe; des Isolators aus seiner Leitung geblasen, und zwar derart, daß dieser aus der Leitung ausströmende Reingasstrom in der Nähe des Isolators eine Art Sperrzone aus staubfreiem Gas schafft, durch welche dem staubführenden Gas der Zutritt zu den Isolatoren verwehrt wird.The invention described below provides an apparatus to To protect the insulators against dust deposits, a stream becomes pure Gas through the high-voltage line 'itself into the chamber interior and into nearby; of the insulator blown out of its line, in such a way that this stream of clean gas flowing out of the line in the vicinity of the isolator creates a kind of exclusion zone creates from dust-free gas, through which the dust-carrying gas access the isolators are denied.

Wesentlich bei der Erfindung ist, daß dieses >,Sperrgas« nicht durch eine besondere Gaszuführungsleitung, sondern durch die rohrförmig ausgebildete Hochspannungsleitung selbst in den Gasraum hineingeführt wird. Dieser Reingasstrom kann ein Luftstrom sein, der von der äußeren Atmosphäre entnommen wird oder aber dem gereinigten Gase selbst, wenn die Art des zu reinigenden Gases eine Vermischung mit Luft nicht zuläßt.It is essential in the invention that this "sealing gas" does not pass through a special gas supply line, but through the tubular high-voltage line is even introduced into the gas space. This stream of clean gas can be an air stream which is taken from the external atmosphere or the purified gases even if the type of gas to be cleaned does not allow it to mix with air.

Wesentlich ist bei der Vorrichtung nach der Erfindung, daß dieser Reingas- oder Luftstrom nicht die Isolatorenoberflächeselbst bespült, sondern nur die Umgebung des Isolators gegen den Staubgasraum hin absperrt. In der Zeichnung ist eine beispielsweise Ausführung der Vorrichtung dargestellt, und zwar für einen Durchführungsisolator, der in bekannter Weise in einer seitlichen Nische an der Reinigerkammier untergebracht ist. In sinngemäßer Abänderung kann natürlich die Vorrichtung auch für einen Tragisolator im Innern der Kammer angewendet werden. ES `bezeichnen in der Abbildung: r die Reinigerkammer, in, welcher die Elektroden untergebracht sind und welche vom staubführenden Gas durchzogen wird, z die seitliche Isolatorennische, 3 einen Durchführungsisolator, q. die Hochspannungsleitung, welche als Gasrohr ausgeführt ist, 5 Anschlußstutzen für die Reingaszuführung, 6 Absperrorgan dieser Leitung, 7 Schlitze oder Löcher in der Gaszuführung, aus welchen das Schutzgas in das Innere der Kammer austritt.It is essential in the device according to the invention that this Clean gas or air flow does not flush the insulator surface itself, but only the environment of the isolator closes off from the dust gas space. In the drawing an example embodiment of the device is shown, for one Bushing insulator, which is in a known manner in a side niche on the Reinigerkammier is housed. In a corresponding change, of course, the Device can also be used for a support insulator inside the chamber. IT In the illustration, `denote: r the detergent chamber in which the electrodes are housed and which is permeated by the dust-carrying gas, e.g. the lateral insulator niche, 3 a bushing insulator, q. the high-voltage line, which is designed as a gas pipe is, 5 connecting pieces for the clean gas supply, 6 shut-off device of this line, 7 slots or holes in the gas supply, from which the protective gas enters the interior exits the chamber.

Die Hochspannungsleitung q. ist nach unten hin mit der Stromzuführung von dem Umformer her verbunden. Der Anschlußstutzen 5 dient zur Zuführung des Schutzgases bzw. der Luft.The high voltage line q. is down with the power supply connected by the converter. The connection piece 5 is used to supply the protective gas or the air.

Das Schutzgas kann entweder in die Kammer eingesaugt werden, wenn in derselben Unterdruck herrscht, oder aber durch ein besonderes Gebläse aus der Reingasleitung abgesaugt und durch den Stutzen 5 in der Leitung ¢ eingeblasen werden.The protective gas can either be sucked into the chamber, if in the same negative pressure prevails, or by a special fan from the The clean gas line is sucked off and blown in through the nozzle 5 in the line ¢.

Die Wirkungsweise der Vorrichtung ist klar und ergibt sich aus der Beschreibung und Zeichnung.The operation of the device is clear and results from the Description and drawing.
