Abstract

Die Düse zum Einbringen und Dosieren eines Behandlungsmediums in den Abgasstrom bei Verbrennungsprozessen umfasst ein Düsenrohr (2) und einen im Querschnitt runden inneren Verdrängerkörper (1) zur Bildung eines Düsenringspaltes (14). Der Verdrängerkörper (1) begrenzt innerhalb des Düsenrohres (2) einen Mischraum (18) und weist an diesem Ende eine Verjüngung (3) auf, mit der er an einem Zuführrohr (5) für das Behandlungsmedium ausschließlich gehalten ist. Das Zuführungsrohr (5) durchquert einen Druckraum (6.1), welches zwei axiale Begrenzungswände (4,7) aufweist. In diesen Begrenzungswänden ist das Zuführungsrohr gehalten, wobei in der Begrenzungswand (4) eine Halterung (12) vorgesehen ist, die das hindurchströmen des Trägermediums aus dem Druckraum (6.1) zum Düsenspalt (14) ermöglicht.

Figure imgaf001
The nozzle for introducing and metering a treatment medium into the exhaust gas flow in combustion processes comprises a nozzle tube (2) and an internal displacement body (1) which is round in cross section to form a nozzle ring gap (14). The displacer (1) bounded within the nozzle tube (2) has a mixing space (18) and has at this end a taper (3), with which it is exclusively held on a feed tube (5) for the treatment medium. The supply pipe (5) passes through a pressure chamber (6.1), which has two axial boundary walls (4,7). In these boundary walls, the supply pipe is held, wherein in the boundary wall (4) has a holder (12) is provided, which allows the flow of the carrier medium from the pressure chamber (6.1) to the nozzle gap (14).
