Abstract

Verfahren zur Regeneration von beladenen Rußfiltern zur Filterung von Gasen und Abgasen, bei dem das Abgas (6) vor Durchtritt durch den Filter (2) mit Heizmitteln (3) aufgeheizt wird, wobei man mittels des Heizmittels (3) mindestens einen Abgasteilstrom innerhalb des Abgasrohres (1), das dem Filter (2) das zu filternde Abgas (6) zuführt, ausbildet und zusätzlich derart erhitzt, daß der Teilstrom des Abgases (6) in den Filter (2) mit höherer Temperatur als der des anderen Teilstroms eintritt.

Figure 00000001
Process for the regeneration of loaded soot filters for filtering gases and exhaust gases, in which the exhaust gas (6) is heated with heating means (3) before passing through the filter (2), with at least one partial exhaust gas flow within the exhaust pipe using the heating means (3) (1) which supplies the filter (2) with the exhaust gas (6) to be filtered, forms and additionally heats such that the partial flow of the exhaust gas (6) enters the filter (2) at a higher temperature than that of the other partial flow.
