Description

Niederschlagselektrode für - elektrische -Gasreinigungsanlagen. 'Bei Niederschlagselektroden für elektrische Gasreinigung, bei denen das Gas die Elektrode quer durchströmt, setzt sich zwar der feine Staub an der gewöhnlich netzartigen Niederschlagselektrode ab. Es hat sich aber gezeigt, daB die größeren Staubteilchen, die durch. die Zusammenballung des Staubes unterder Einwirkung des elektrischen Feldes entstehen, infolge ihrer größeren lebendigen Kraft auch in nächster Nähe der Niederschlagselektrode sich geradlinig weiterbewegen, zum größten Teil durch die Durchgangsöffnungen hindurchtreten und so erneut in den Gasstrom gelangen.Precipitation electrode for - electrical gas cleaning systems. 'At Collecting electrodes for electrical gas cleaning, in which the gas is the electrode Flowing across it, the fine dust settles on the usually reticulated Collecting electrode. It has been shown, however, that the larger dust particles by. the agglomeration of dust under the action of the electric Field arise, due to their greater living power, also in the immediate vicinity the collecting electrode continue to move in a straight line, for the most part through pass through the passage openings and so enter the gas flow again.

Bei der Niederschlagselektrode nach der Erfindung wird dieser Nachteil dadurch vermieden, daß oberhalb jeder Durchtritts,öffnung in der Elektrode auf der dem Gasstrom abgewendeten Seite ein unter spitzem Winkel gegen die Elektrode nach unten gerichteter Lappen angeordnet ist. Die zusammengeballten Staubteilchen treten durch die Öffnungen hindurch, prallen an den Lappen an und werden nach unten abgelenkt. Durch die an den Elektroden angebrachten Lappen werden also auch die zusammengeballten Staubteilchen aus dem Gasstrom entfernt.In the case of the collecting electrode according to the invention, this disadvantage becomes apparent thereby avoided that above each passage, opening in the electrode on the the side facing away from the gas flow follows an acute angle towards the electrode is arranged downward lobes. The agglomerated dust particles kick through the openings, hit the tabs and are deflected downwards. The tabs attached to the electrodes also cause the clumps to become clumped together Dust particles removed from the gas flow.

Die Elektrode gemäß der Erfindung hat die neue Wirkung, daß die feinen Staubteilchen sich fast ausschließlich an den zum Gasstrom senkrecht stehenden Wandungen der Elektrode absetzen. Die Elektroden gemäß der Erfindung wirken sowohl für feine als für grobe Staubteilchen gleich günstig, indem die ersten hauptsächlich durch Anhaften an der Elektrode, die zweiten hauptsächlich durch mechanische. Ablenkung aus dem Gasstrom entfernt werden.The electrode according to the invention has the new effect that the fine Dust particles are almost exclusively found on the walls that are perpendicular to the gas flow the electrode. The electrodes according to the invention work for both fine as equally favorable for coarse dust particles, in that the first mainly through Adherence to the electrode, the second mainly by mechanical. diversion be removed from the gas stream.

Es sind zwar schon Niederschlagselektroden bekannt, bei denen ebenfalls eine Ablenkung des, Gasstromes durch schräg nach unten gerichtete Flächenelemente erzielt wird. Es fehlen bei diesen bekannten Elektroden aber die senkrechten Elektrodenwände, an denen sich der feine Staub absetzen kann. Diese Elektroden wirken daher in bezug auf die feinen Staubteilchen ungünstig.Precipitation electrodes are already known, which are also used a deflection of the gas flow by obliquely downwardly directed surface elements is achieved. In these known electrodes, however, the vertical electrode walls are missing, where the fine dust can settle. These electrodes therefore act in relation unfavorable on the fine dust particles.

Die. Abb. i und 2 zeigen eine Niederschlagselektrode gemäß der Erfindung in Ansicht und ,Querschnitt. i sind die Öffnungen, 2 die schräg nach unten gerichteten Lappen. Dies sind, wie aus Abb.2 ersichtlich, etwa unter gegen die Platte nach dem Boden zu geneigt. Die groben Staubteilcben, die in Abb.2 mit dem Gasstrom von links nach rechts durch die Öffnungen hindurchtreten, werden durch die Lappen nach unten abgelenkt und so aus dem Gasstrom entfernt.The. Figs. I and 2 show a collecting electrode according to the invention in elevation and, cross-section. i are the openings, 2 the diagonally downwards Rag. As can be seen from Fig. 2, these are approximately below against the plate after the Ground too sloping. The coarse dust particles, those in Fig. 2 with the gas flow from the left Passing to the right through the openings are down through the flaps deflected and thus removed from the gas flow.
