Description

Sprühelektrode für die elektrische Gasreinigung. Bei elektrischen Gasreinigungsanlagen werden als Sprühelektroden die verschiedentlichsten festen oder elastischen Gebilde aus elektrisch geeigneten Materialien verwendet.Spray electrode for electrical gas cleaning. With electrical Gas cleaning systems are used as spray electrodes, the most varied of solid or elastic structures made of electrically suitable materials are used.

Alle diese Anordnungen hatten bisher einen wesentlichen Nachteil. Er besteht bei den bekannten starren Sprühelektroden darin, daß diese schwer in die Senkrechten und genau zentral zur Sammelelektrode einzustellen sind und dies unmöglich wird, wenn durch Temperaturunterschiede gewisse Spannungen in das Material gebracht werden, die naturgemäß ein Verziehen verursachen.All of these arrangements have hitherto suffered from a major disadvantage. It consists in the known rigid spray electrodes that they are difficult in the vertical and exactly central to the collecting electrode are to be set and this becomes impossible if, due to temperature differences, certain stresses in the material which naturally cause warping.

Die elastischen Sprühelektroden hängen sich leichter senkrecht ein und sind gegen Temperaturschwankungen unempfindlich, sind aber schwer abzureinigen, schwingen noch lange nach der Abreinigung aus und sind nachdem wieder schwer einzustellen.The elastic spray electrodes hang more easily vertically and are insensitive to temperature fluctuations, but are difficult to clean off, oscillate long after cleaning and are difficult to adjust again afterwards.

Besonders bei den festen Sprühelektroden, die leichter durch rhythmischeStöße in gleichmäßige Erschütterung gebracht werden können als die elastischen, und die nach der Abreinigung schneller ausschwingen als die elastischen Elektroden, fällt der erwähnte Nachteil um so mehr ins Gewicht.Especially with the fixed spray electrodes, which are easier to use with rhythmic impacts can be brought into uniform vibration as the elastic, and the Swing out faster than the elastic electrodes after cleaning, falls the disadvantage mentioned is all the more significant.

Gegenstand der Erfindung ist nun eine starre Elektrode, die Temperatureinflüssen besser gewachsen ist als die bisher bekannten, und die leicht und schnell abgereinigt werden kann.The subject of the invention is now a rigid electrode, the temperature influences has grown better than the previously known ones, and cleaned easily and quickly can be.

Sie besteht aus einem starren metallischen Röhrchen von einem Durchmesser, der durch den.Coronagradienten bedingt ist, und dessen Länge beliebig nach der Länge der Sammelelektrode gewählt werden kann. Dieses Röhrchen ist über einen elastischen angespannten Draht oder Drahtseil gezogen, das hierauf genau zentral und senkrecht eingestellt wird. Temperaturschwankungen haben auf das Röhrchen keinen nennenswerten Einfluß.It consists of a rigid metal tube with a diameter which is conditioned by the Corona gradient, and its length arbitrarily according to the length the collecting electrode can be selected. This tube is about an elastic tense wire or wire rope pulled, which then exactly centrally and vertically is set. Temperature fluctuations have no noticeable effect on the tube Influence.

Beim Abschütteln bleibt der Draht vollkommen in Ruhe, und nur das Röhrchen wird in rasche Auf- und Abwärtsbewegung versetzt, beispielsweise durch eine kleine Preßluft- oder elektrische Vorrichtung.When shaking off the wire remains completely at rest, and only that The tube is set in rapid upward and downward movement, for example by a small compressed air or electrical device.

Nachdem der Staub abgefallen ist, kann die Erschütterung sofort durch Abstellen des Treibmittels unterbrochen werden.After the dust has fallen off, the shock can come through immediately Stopping the propellant are interrupted.

Zum Unterstützen der Abreinigung kann das Röhrchen mit kleinen Löchern versehen sein, durch welche während des Abklopfens ein Gas- oder Luftstrom von innen nach außen gedrückt werden kann. Auf diese Weise wird die außen sitzende Staubschicht aufgelockert und die Abreinigung unterstützt und auch verhindert, daß zwischen Draht und Rohrinnenfläche sich Staubablagerungen bilden, die ein leichtes Gleiten zwischen Rohr und Draht verhindern könnten.The tube with small holes can be used to aid cleaning be provided, through which a gas or air flow from the inside during tapping can be pushed outwards. In this way, the layer of dust sitting on the outside becomes loosened up and supports cleaning and also prevents between wire and inner surface of the pipe, dust deposits form, which slide easily between Pipe and wire could prevent.

In der Abbildung ist A das Sprühröhrchen, a seine Durchbrechungen, B der durch das Röhrchen .gezogene Draht, C die Sammelelektrode.In the figure , A is the spray tube, a is its perforations, B is the wire drawn through the tube, C is the collecting electrode.
