Abstract

Die Erfindung betrifft einen elektrostatischen Abscheider (1, 1') für eine Abgasleitung (2) einer Abgasreinigungsanlage, ein Heizungssystem zur Erzeugung von Energie mittels Verbrennen von einem Energieträger mit einem elektrostatischen Abscheider (1, 1') und ein Verfahren zur Reduzierung von Ablagerungen von Partikeln eines Abgasstroms (P) an einer Elektrode (6) eines elektrostatischen Abscheiders (1, 1') eines Heizungssystems.The invention relates to an electrostatic precipitator (1, 1 ') for an exhaust pipe (2) of an exhaust gas purification system, a heating system for generating energy by burning an energy source with an electrostatic precipitator (1, 1') and a method for reducing deposits of Particles of an exhaust gas stream (P) at an electrode (6) of an electrostatic precipitator (1, 1 ') of a heating system.

Es ist eine Aufgabe der Erfindung, einen elektrostatischen Abscheider (1, 1') und ein Heizungssystem zu schaffen, welche die Nachteile gemäß dem Stand der Technik überwinden und die insbesondere eine Ablagerung von Partikeln auf der Elektrode (6) verhindern oder reduzieren.It is an object of the invention to provide an electrostatic precipitator (1, 1 ') and a heating system which overcome the disadvantages of the prior art and in particular prevent or reduce deposition of particles on the electrode (6).

Gekennzeichnet ist der elektrostatische Abscheider (1, 1') dadurch, dass dieser ein beheizbares Partikelabweisemittel umfasst, welches verhindert, dass sich Partikel an der Elektrode (6) ablagern, wobei die Elektrode (6) und das beheizbare Partikelabweisemittel (9b) zumindest teilweise als ein gemeinsames Bauteil als direktbeheizte Elektrode ausgebildet sind. Gekennzeichnet ist das Heizungssystem dadurch, dass dieses den erfindungsgemäßen elektrostatischen Abscheider (1, 1') umfasst.

Figure imgaf001
The electrostatic precipitator (1, 1 ') is characterized in that it comprises a heatable particle repelling agent, which prevents particles from depositing on the electrode (6), the electrode (6) and the heatable particle repelling agent (9b) at least partially as a common component is formed as a directly heated electrode. The heating system is characterized in that it comprises the electrostatic precipitator (1, 1 ') according to the invention.
