Description

Verfahren zur Reinigung von Gaset, mittels Igehrphasenstroms. Eisher wurde Drehstronx zur elektrischen Gasreinig nur in der Weise verwandt; daß die entsprechend hoch herauftransfor- nerte S'pannu'ng direkt den Sprühelektroden zugefu'bxt warde@ Dabei entsteht ein elek- trostatisches Drehfeld, dlas st durch ne- gartive wie auch positive Aufladung der Sprühelektroden, also durch negatives und positives Spr, gekennzeichnet ist. Nach der vorliegenden E'Tfindung geschieht die Erzes dies Drehfeldes mit derselben Elektrodenanordnung wie bei dem vorer- wahnten bek=nien Verfahren, aber mit Plia.- segspennungen, die in an sich bekannter Weise gleichgerichtet sind-. Damit ist die Möglichkeit gegen, zur Staubabscheidurig Drehfelder zu veiwenäen, bei denen ent- weder nur positives oder nur negatives Sprühen erfolgt: Dhs dreiphasige positive Drehfeld z. E. kommt in. der Wfeise zustande, daf£ die Sprühdrähte der drei Phasen mit eirau P%enunterschied von r2o° der Reihe nach Uuf den höchsten positiven Spannungs- betrag gebracht werden. Die Pericidenzahl des Dreiphasenstroms kann dabei beliebig sein. Gegenüber der bekannten Verwendung gleichgerichteten Ennphasenwechselstromes ergibt die vorliegende Anordnung den Vorteil, daß zu den Wirkungen der Gleichspannung die für die Staubabscheidung vorteilhafte Wirkung dies elektrostatischen Drehfeldes hinzugefügt wird. Process for the purification of Gaset, using Igehrphasenstrom. Eisher turned Drehstronx into an electric one Gas purifier only related in the way; that the correspondingly high The voltage applied directly to the spray electrodes zugefu'bxt warde @ This creates an elec- static rotating field, which is thru ne- gartive as well as positive charging of the Spray electrodes, i.e. by negative and positive Spr, is marked. According to the present finding, it happens the ore of this rotating field with the same Electrode arrangement as in the previous were aware of procedures, but with Plia. segspennungen, which in itself are known Way are rectified-. So that is Opportunity against, for dust separation To avoid rotating fields in which neither only positive nor only negative Spraying is done: Dhs three-phase positive Rotating field z. E. comes about in the wfeise, that the spray wires of the three phases with eirau P% difference from r2o ° of the series according to the highest positive voltage amount to be brought. The number of pericids the three-phase current can be arbitrary be. Compared to the known use of rectified single-phase alternating current, the present arrangement has the advantage that the effect of this electrostatic rotating field, which is advantageous for dust separation, is added to the effects of the direct voltage.

Gegenüber der bekannten Drehfeldmethode besteht eine wesentliche Verbesserung darin, daß im Drehfeld jetzt nur mit einem bestimmten Aufladungssinn der Staubteilchen, z. B. durch positive Ionen, gearbeitet wird. Es fallen also Umladungen der Teilchen fort, und die Ausscheidung wird gegenüber der gewöhnlichen Drehfeldabscheid@ung vorteilhafter.There is a significant improvement over the known rotating field method in the fact that in the rotating field the dust particles now only have a certain sense of charge, z. B. by positive ions is worked. So there is a charge reversal of the particles continues, and the separation is compared to the usual rotating field separation more advantageous.

Die Zeichnung zeigt ein Schaltungsbeispiel für eine mit Dreiphasenstrom betriebene Anlage. Darin bedeutet i einen Drehstromhochspannungstransfoxmator, 2,3,4 d'ie Phasenleitungen. 5 deuten drei Quecksilbergleichrichter an, die jedoch durch: Gleichrichter beliebiger A1rt, auch durch rotierende Gleichrichter,- ersetzt werden können. 6, 7, 8 sind; die Sprühelektroden, 9 die Hochspannungsdurchführungen, io ist das Gehäuse. In der !Mitte der drei Sprühdrähte kann in an sich bekannter Weise als Nulleiter ein zylindrischer Starb o. dgl. angebracht sein.The drawing shows an example circuit for a three-phase current operated system. Therein i means a three-phase high-voltage transformer, 2,3,4 d'ie phase lines. 5 indicate three mercury rectifiers, which, however, are characterized by: Rectifiers of any type, including rotating rectifiers, can be replaced can. 6, 7, 8 are; the spray electrodes, 9 the high-voltage bushings, io is the case. In the middle of the three spray wires can be done in a manner known per se as a neutral conductor a cylindrical death o. The like. Be attached.

Die Schaltung der Sprühelektroden kann in Stern- oder Dreieckschaltung erfolgen.The spray electrodes can be connected in star or delta connection take place.
