Description
Anordnung zum Druckausgleich an Flüssigkeitsisolatoren für Elektrofilter Zum Abschluß der Nebenkammer für die Hochspannungseinführung von Elektrofiltern werden vielfach mit Öl o. dgl. gefüllte Flüssigkeitsverschlüsse verwendet. Da nun die Gase in dem Elektrofilter starken Druckschwankungen unterworfen sind, so kann es vorkommen, daß der Flüssigkeitsspiegel der in dem Verschluß vorhandenen Flüssigkeit in seiner Höhe stark schwankt und bei stoßartigen Druckänderungen sogar die Flüssigkeit aus dem Verschluß herausgetrieben wird. Man hat nun diese Schwierigkeit dadurch zu beseitigen versucht, daß man den Isolatorenraum und die Filterkammer durch eine Druckausgleich leitung miteinander verbindet. Es hat sich hierbei jedoch der Nachteil gezeigt, daß noch teilweise ungereinigtes Gas aus der Filterkammer über die Ausgleichleitung in den Isolatorenraum eindringen kann. Im folgenden wird nun gezeigt, wie sich dieser Übelstand beheben läßt.Arrangement for pressure equalization on liquid isolators for electrostatic precipitators At the end of the secondary chamber for the high-voltage introduction of electrostatic precipitators Liquid seals filled with oil or the like are often used. Because now the gases in the electrostatic precipitator are subject to strong pressure fluctuations, so can it happens that the liquid level of the liquid present in the closure in its height fluctuates strongly and with sudden changes in pressure even the liquid is driven out of the breech. You now have this difficulty because of it Tried to eliminate that the isolator space and the filter chamber through a Pressure equalization line connects with each other. However, this has the disadvantage shown that still partially unpurified gas from the filter chamber via the equalization line can penetrate into the isolator room. The following shows how this Can fix the problem.
Erfindungsgemäß ist in der Ausgleichleitung ein -zwar nachgiebiges, aber gasundurchlässiges Zwischenglied, z. B. eine Membran, ein Ballon, ein Kolben o. dgl., angeordnet, das zwar einen Druckausgleich gestattet, aber den Übertritt von Gasen aus der Filterkammer in den Isolatorenraum verhindert. Auf diese Weise werden Verschmutzungen des Isolatorenraumes mit Sicherheit vermieden.According to the invention, in the equalizing line there is a - although flexible, but gas-impermeable intermediate member, e.g. B. a membrane, a balloon, a piston o. The like. Arranged, which allows a pressure equalization, but the transfer of gases from the filter chamber in the isolator room is prevented. In this way Soiling of the isolator room is avoided with certainty.
In der Figur ist ein Ausführungsbeispiel der Erfindung im Aufriß dargestellt. i ist ein Elektrofilter, in dem in an sich bekannter Weise die nicht besonders dargestellten Sprüh- und Niederschlagselektroden aufgehängt sind. Den Sprühelektroden wird die Hochspannung durch den Leiter ? von außen her zugeführt. Die Einführungsstelle des Lei-* ters 2 ist in eine Nebenkammer 3 verlegt, in deren oberer Wand der Durchführungsisolator 4. angeordnet ist. Die Nebenkammer 3_ ist mit der Filterkammer i durch ein Rohrstück 5 verbunden. Um zu verhindern. daß die staubhaltigen Gase aus der Filterkammer i durch dieses Rohrstück 5 in das Innere der Nebenkammer 3, in welcher der Isolator 4 angeordnet ist, eindringen, ist ein Flüssigkeitsverschluß vorgesehen, der aus einer auf dem Leiter 2 angebrachten Glocke 6 besteht, die in die Flüssigkeit 7 eintaucht, welche in den unteren Teil der Nebenkammer 3 eingefüllt ist. Um einen Druckausgleich zwischen dem Innenraum der 1Tebenkammer 3 und der Filterkammer i herbeizuführen, ist eine Druckausgleichleitung 8 vorgesehen. In diese Druckausgleichleitung ist nun ein aus zwei trichterartigen Hälften bestehender Körper 9 eingefügt, bei dem zwischen den beiden Hälften eine elastische Membran io eingespannt ist, welche zwar den Durchtritt der Gase von der Filterkammer nach dem Innenraum der Nebenkammer 3 verhütet, aber in weiten Grenzen einen Druckausgleich zwischen diesen beiden Räumen gestattet.In the figure, an embodiment of the invention is shown in elevation. i is an electrostatic precipitator in which, in a manner known per se, the not specifically shown Spray and precipitation electrodes are suspended. The spray electrodes is the High voltage through the conductor? fed from the outside. The introduction point of the Conductor 2 is laid in a secondary chamber 3, in the upper wall of which the bushing insulator is located 4. is arranged. The secondary chamber 3_ is connected to the filter chamber i through a piece of pipe 5 connected. To prevent. that the dusty gases from the filter chamber i through this pipe section 5 into the interior of the secondary chamber 3, in which the insulator 4 is arranged to penetrate, a liquid seal is provided, which consists of a bell 6 attached to the conductor 2, which is immersed in the liquid 7, which is filled in the lower part of the secondary chamber 3. To equalize pressure to bring about between the interior of the secondary chamber 3 and the filter chamber i, a pressure equalization line 8 is provided. In this pressure equalization line is now inserted a body 9 consisting of two funnel-like halves, in which an elastic membrane is clamped between the two halves, which is true the passage of the gases from the filter chamber to the interior of the secondary chamber 3 prevents, but within wide limits, an equalization of pressure between these two spaces allowed.
