Abstract

Die Erfindung betrifft einen elektrostatischen Abscheider (1), insbesondere für eine Abgasleitung (2) einer Abgasreinigungsanlage, mit einem Strömungskanal (3) mit einer Kanalwandung (4) und einem Kanalinneren (5), durch welchen ein partikelbeinhaltendes Abgas (P) in einer Strömungsrichtung strömt, und einer sich in dem Kanalinneren (5) im Wesentlichen in Strömungsrichtung (P) erstreckenden Elektrode (6), zur Bildung eines elektrischen Feldes zwischen der Elektrode (6) und der Kanalwandung (4), sowie ein Heizungssystem mit einem elektrostatischer Abscheider (1).The invention relates to an electrostatic precipitator (1), in particular for an exhaust line (2) of an exhaust gas purification system, having a flow channel (3) with a channel wall (4) and a channel interior (5), through which a particle-containing exhaust gas (P) in a flow direction flows, and in the channel interior (5) substantially in the flow direction (P) extending electrode (6) for forming an electric field between the electrode (6) and the channel wall (4), and a heating system with an electrostatic precipitator ( 1).

Es ist eine Aufgabe der Erfindung, einen elektrostatischen Abscheider (1) und ein Heizungssystem zu schaffen, welche die Nachteile gemäß dem Stand der Technik überwinden und die insbesondere das Versagen des elektrischen Auflademechanismus', das Corona-Quenching, verhindern.It is an object of the invention to provide an electrostatic precipitator (1) and a heating system which overcomes the disadvantages of the prior art and which in particular prevent the failure of the electrical charging mechanism, the corona quenching.

Gekennzeichnet ist der elektrostatische Abscheider (1) dadurch, dass zur Verbesserung der Abscheideleistung des elektrostatischen Abscheiders längs der Elektrode (6) an mindestens zwei Stellen jeweils mindestens zwei Sprühelektrodenabschnitte (6a) angeordnet sind, wobei die radialen Erstreckungen der an einer Stelle angeordneten Sprühelektrodenabschnitte (6a) im Wesentlichen gleich sind und sich von den radialen Erstreckungen der an einer anderen Stelle angeordneten Sprühelektrodenabschnitte (6a) unterscheiden.

Figure imgaf001
The electrostatic precipitator (1) is characterized in that, to improve the separation efficiency of the electrostatic precipitator, at least two spray electrode sections (6a) are arranged at least two locations along the electrode (6), the radial extensions of the spray electrode sections (6a ) are substantially the same and differ from the radial extents of the diffuser electrode portions (6a) disposed at a different location.
