Description

Verfahren zur Säuberung der Elektroden von Elektrofilteranlagen mit zwei oder mehreren hintereinandergeschalteten elektrischen Feldern Bei Elektrofilteranlagen mit zwei oder mehr hintereinandergeschalteten elektrischen Feldern ist es bekannt, die einzelnen Elektrodengruppen unabhängig voneinander und in zeitlicher Aufeinanderfolge zum Zwecke der Säuberung zu erschüttern. Während bisher die Erschütterung aller Elektrodengruppen in demselben Zeitmaße erfolgte, kommt es bei der Erfindung darauf an, daß, in Richtung des Gasstromes gesehen, also mit zunehmender Gasreinheit, das Zeitmaß der aufeinanderfolgenden einzelnen Erschütterungen von der einen Elektrodengruppe zur nächsten vergrößert wird. Die Erfindung beruht auf der Erkenntnis, daß die der Eintrittsseite des zu reinigenden Gases zunächstliegenden Elektroden bei weitem mehr Schwebekörper ansetzen als die nachfolgenden Elektroden und infolgedessen öfter erschüttert werden müssen als die Elektroden, die in dem schon teilweise gereinigten Gas liegen und infolgedessen einen geringeren Staubansatz aufweisen.Process for cleaning the electrodes of electrostatic precipitators with two or more electrical fields connected in series in electrostatic precipitator systems with two or more electric fields connected in series, it is known the individual electrode groups independently of one another and in chronological order to shake for the purpose of cleansing. While so far the shock of everyone Electrode groups took place in the same amount of time, it depends on the invention indicates that, seen in the direction of the gas flow, i.e. with increasing gas purity, the Time measure of the successive individual vibrations from one group of electrodes is enlarged to the next. The invention is based on the knowledge that the On the inlet side of the gas to be cleaned, the electrodes lying next to it by far Apply more floats than the following electrodes and consequently more often have to be shaken than the electrodes in the already partially cleaned Gas lie and as a result have a lower amount of dust.

Die Erfindung bezieht sich sowohl auf solche Elektrofilteranlagen, die aus zwei oder mehr hintereinandergeschalteten Einzelfiltern bestehen, wie ,auf Anlagen, bei denen zwei oder mehr hintereinandergeschaltete Elektrodengruppen in demselben Raum untergebracht sind.The invention relates to such electrostatic precipitators, which consist of two or more individual filters connected in series, such as, on Systems in which two or more electrode groups connected in series in are housed in the same room.

Die Erschütterung kann auf beliebige Weise sowohl mechanisch, d. h. selbsttätig, wie von Hand vorgenommen werden, sofern nur dafür gesorgt wird, daß bei der Erschütterung der Elektroden der zweiten oder nachfolgenden Stufen ein größeres Zeitintervall eingehalten wird als bei der Elektrodengruppe der vorangehenden Stufe.The vibration can be mechanical, i. H. automatically, as if carried out by hand, provided that it is only ensured that if the electrodes of the second or subsequent stages are shaken, a larger one Time interval is observed than with the electrode group of the previous stage.
