Description

Sprühelektrode für die elektrische Gasreinigung. Bei der elektrischen Reinigung von Gasen. die stark ätzende Bestandteile enthalten, bewähren sich die gewöhnlichen Sprühelektroden in Form von metallischen Drähten o. dgl. nicht, da sie durch die ätzenden Gase in kurzer Zeit zerstört werden.Spray electrode for electrical gas cleaning. With the electric Purification of gases. which contain highly corrosive components, the Ordinary spray electrodes in the form of metallic wires or the like. Not because they are destroyed in a short time by the corrosive gases.

Erfindungsgemäß werden daher für die Reinigung ätzender Gase Sprühelektroden verwendet, die aus einem Schmelzfluß von Glas. Porzellan. Quarz. Steingut oder ähnlichen Stoffen und aus elektrisch leitenden Stoffen (Metalle wie etwa Wolfram, Nickel, Kupfer. Silber, Gold und Platin) bestehen. Das Metall wird dabei dem Schmelzfuß in derartigen Mengen zugeführt. daß die neue Sprühelektrode eine genügende elektrische Leitfähigkeit aufweist. Trotzdem wird sie aber im Gegensatz zu metallischen Elektroden von. den ätzenden Gasen nicht angegriffen.According to the invention, spray electrodes are therefore used for cleaning corrosive gases used made from a melt flow of glass. Porcelain. Quartz. Earthenware or similar Materials and electrically conductive materials (metals such as tungsten, nickel, Copper. Silver, gold and platinum). The metal becomes the fusible foot supplied in such amounts. that the new spray electrode is sufficiently electrical Has conductivity. In spite of this, however, it is unlike metallic electrodes from. not attacked by the corrosive gases.

Die Herstellung des Schmelzflusses kann z. B. dadurch erfolgen, daß man das 'Metall auf elektrischem Wege in feinstes Pulver zerstäubt und dieses Pulver dann dem Glastluli zusetzt. Es bildet sich eine kolloidale Lösung zwischen dem Metall und dem Schmelztiuß.The production of the melt flow can e.g. B. be done in that the metal is electrically atomized into the finest powder and this powder then clogs the glass luli. A colloidal solution forms between the metal and the melting pot.

In vielen Fällen wird es zweckmäßig sein, als Sprühelektrode einen Körper (Stab oder Rohr) aus Nichtleitern, z. B. aus Porzellan oder Quarz, zu verwenden und diesen Körper mit einem derartigen Schmelzfluß zu überziehen. Der Überzug gewährleistet eine genügende Zuleitung der auszusprühenden Elektrizität. Um die Sprühwirkung zu unterstützen, kann man die Oberfläche einer derartigen Elektrode in üblicher Weise mit einer scharfen Riffelung versehen. Die Elektrizität strahlt dann bekanntlich von den einzelnen Spitzen oder Kanten der Riffelung aus.In many cases it will be useful to use a spray electrode Body (rod or tube) made of non-conductors, e.g. B. porcelain or quartz to use and to coat this body with such melt flow. The coating ensures a sufficient supply of electricity to be sprayed. To the spray effect too support, you can the surface of such an electrode in the usual way provided with a sharp corrugation. As is well known, the electricity then radiates from the individual tips or edges of the corrugation.

Es ist bereits eine Sprühelektrode bekannt, die aus Silit besteht. Eine derartige Silitelektrode erweist sich aber für die Reinigung von Gasen, die stark ätzende Bestandteile enthalten, weniger geeignet, da sie von diesen verhältnismäßig stark angegriffen wird.A spray electrode made of silite is already known. Such a silicon electrode has proven itself for the purification of gases that contain highly corrosive components, less suitable as they are proportionate to these is strongly attacked.
