Description

Verfahren zur selbsttätigen Regelung der Spannung im Elektrofilter Die Erfindung betrifft ein Verfahren, gemäß dem die Spannung in einem Elektrofilter selbsttätig geregelt wird. Man hat schon vorgeschlagen, diese selbsttätige Regelung der Spannung direkt oder indirekt durch eine vom jeweiligen Zustande des Rohgases abhängige Vorrichtung vornehmen zu lassen, wobei zweckmäßig die Spannung schon vor Eintritt des Gases in das Elektrofilter auf dessen Zustand selbsttätig eingestellt wird. Und zwar werden die bekannten Verfahren gewöhnlich in der Weise durchgeführt, daß die Schwankungen der Leitfähigkeit des Gases zur Steuerung des Spannungsreglers benutzt werden. Zu diesem Zweck werden z. B. in die Rohgasleitung zwei gegenüberliegende leitende Platten eingebaut, die unter Benutzung der Leitfähigkeit des zwischen ihnen hindurchfließenden Gases über diese Gasstrecke hinweg einen Stromkreis schließen, dessen Schwankungen den Spannungsregler steuern. Bei Einrichtungen dieser Art kann es immerhin leicht vorkommen, daß sich die leitenden Platten mit Staub überziehen und daß infolgedessen die Einrichtung sehr bald nicht mehr einwandfrei arbeitet. Im folgenden wird nun ein neues Verfahren gezeigt, bei dem diese Übelstände beseitigt sind.Process for the automatic regulation of the voltage in the electrostatic precipitator The invention relates to a method according to which the voltage in an electrostatic precipitator is regulated automatically. This automatic regulation has already been proposed the voltage directly or indirectly through one of the respective states of the raw gas Dependent device to be made, with the appropriate voltage already before Entry of the gas into the electrostatic precipitator automatically adjusted to its state will. The known procedures are usually carried out in such a way that that the fluctuations in the conductivity of the gas to control the voltage regulator to be used. For this purpose z. B. in the raw gas line two opposite Conductive plates built in, making use of the conductivity of the between them the gas flowing through it close a circuit via this gas path, whose fluctuations control the voltage regulator. With facilities of this type after all, it is easy for the conductive plates to be covered with dust and that, as a result, the facility very soon ceases to function properly. In the following, a new method is shown in which these deficiencies are eliminated are.

Das neue Verfahren beruht auf der Erkenntnis, daß bei vielen Gasen, insbesondere bei Gichtgasen, die überschlagsneigung fast eindeutig von dem Wasserstoff- und Staubgehalt der Gase abhängig ist. Diese Erkenntnis gibt die Möglichkeit zu einem einfachen Verfahren der selbsttätigen Spannungsregelung.The new process is based on the knowledge that with many gases, especially with blast furnace gases, the tendency to overturn almost clearly from the hydrogen and dust content of the gases is dependent. This realization gives the possibility a simple method of automatic voltage regulation.

Erfindungsgemäß wird die Spannung in dem Elektrofilter in Abhängigkeit von dem Wasserstoff- und Staubgehalt der Gase geregelt. 'Wie Versuche gezeigt haben, läßt sich auf diese Weise eine dauernde einwandfreie Regelung der L`berschlagsspannung und damit auch der Betriebsspannung durchführen.According to the invention, the voltage in the electrostatic precipitator is dependent regulated by the hydrogen and dust content of the gases. 'As experiments have shown In this way, a permanent, perfect control of the flashover voltage can be achieved and thus also the operating voltage.

Eine zur Ausführung dieses Verfahrens geeignete Vorrichtung ist vorteilhaft in der Weise ausgebildet, daß zur Regelung der Spannung ein Wasserstoffmesser und ein Rauchgasprüfer o. dgl. verwendet werden. Diese Geräte werden zweckmäßig in die Gaszuführungsleitung selbst eingebaut.A device suitable for carrying out this method is advantageous designed in such a way that a hydrogen meter and to regulate the voltage a smoke gas detector or the like can be used. These devices are useful in the Gas supply line built in itself.

In den Fällen, wo @es sich darum handelt, die Spannung eines durch reines Gichtgas hindurchgehenden Hochspannungsstromes zu regeln, reicht es praktisch aus, die Regelung der Spannung in Abhängigkeit von dem Wasserstoffgehalt der Gase allein vorzunehmen. Zur Durchführung dieses Verfahrens genügt dann die alleinige Verwendung irgendeines Wasserstoffmessers als Indikator. Es ergibt sich dann also eine besonders einfache Regelungseinrichtung.In those cases where @it is about the tension of one through It is practically sufficient to regulate the high-voltage current passing through pure furnace gas off, the regulation of the voltage depending on the hydrogen content of the gases to undertake alone. The only one is then sufficient to carry out this procedure Use any hydrogen meter as an indicator. So it then arises a particularly simple control device.
