| 摘要 |
<p>The present invention relates to a device for injecting a liquid, particularly an aqueous urea solution, into the flow of exhaust gas by using at least one atomizing nozzle (10) which is designed as a two-component nozzle. The liquid can be mixed with pressurized air when or after exiting from each atomizing nozzle (10) in order for the atomizing nozzle to inject the liquid into the flow of the exhaust gas by means of the pressurized air. The atomizing nozzle (10) or all of separate atomizing nozzles (10) have nozzle base bodies (12), nozzle air flaps (13) and nozzle inserts (14) which are formed as rotating members, wherein each atomizing nozzle (1) can be connected to a nozzle lance (11) by the nozzle base body (12), and the nozzle air flap (13) and the nozzle insert (14) are received and held in the nozzle base body (12).</p> |
