Description

Verfahren zur Säuberung von Vielzellen-Fliehkraft-Staubabscheidern Der Betrieb von Vielzellen-Fliehkraft-Staubabscheidern wird mitunter durch Staubansätze in den Reingasrohren, die auch zu Verstopfungen führen können, gestört, auch Verlagerungen der Staubaustrittsöffnungen können eintreten. Die Gefahr des Auftretens solcher Störungen ist um so größer, je feiner der noch im Reingas enthaltene Staub ist. Die Ursache der Ansätze ist durch verschiedene Einflüsse begründet. Besondere mineralische Bestandteile, elektrostatische Aufladungen, Kondensationserscheinungen usw. begünstigen die Bildung dieser Ansätze.Process for cleaning multi-cell centrifugal dust collectors The operation of multi-cell centrifugal dust collectors is sometimes caused by dust deposits in the clean gas pipes, which can also lead to blockages, disturbed, also displacements the dust outlet openings can enter. The risk of such occurrence The finer the dust still contained in the clean gas, the greater the disturbance. The cause of the approaches is justified by various influences. Special mineral Components, electrostatic charges, condensation phenomena etc. favor the formation of these approaches.

Nach der Erfindung werden in den Reingasrohren auftretende Ansätze oder Verstopfungen in einfachster Weise ohne Außerbetriebsetzung der Staubabscheideanlage dadurch beseitigt, daß Frischluft oder Gas durch die Staubaustrittsöffnungen in die Zellen eingeführt und durch die Reingasrohre abgesaugt wird. Dieses geschieht durch zeitweise und kurzzeitig durchgeführtes Verbinden des Staubsammelrohres, beispielsweise mit der Atmosphäre oder der Gaszuführungsleitung zum Abscheider oder bei Rauchgasreinigungsanlagen mit dem Rauchgaszuführungskanal. Es genügt schon ein wenige Minuten langes Einschalten dieser Spülströmungen, um durch das Mitreißen von grobem Staub innerhalb der Zellen und der Reingasrohre eine Scheuerwirkung hervorzurufen, die zur Beseitigung der Ansätze führt.According to the invention appearing approaches in the clean gas pipes or blockages in the simplest way without putting the dust separation system out of operation thereby eliminates that fresh air or gas through the dust outlet openings in the cells are introduced and aspirated through the clean gas pipes. This happens by intermittently and briefly carried out connecting the dust collection pipe, for example with the atmosphere or the gas supply line to the separator or with flue gas cleaning systems with the flue gas supply duct. Switching on for a few minutes is sufficient these flushing currents in order to by entrainment of coarse dust within the cells and the clean gas pipes cause a scrubbing effect, which to eliminate the Approaches leads.

Während bisher das Reinigen der Vielzellen-Fliehkraft-Staubabscheider zeitraubend und nur bei Außerbetriebsetzung der Abscheideanlage möglich war, erfolgt durch das neue Verfahren die vollkommene Reinigung während des Betriebes.While so far the cleaning of the multi-cell centrifugal dust separator was time-consuming and only possible when the separation system was shut down by the new procedure ensures complete cleaning during operation.
