Abstract (en)

Atomizing nozzle (30) for two substances comprises an annular gap (64) surrounding an outlet opening (52) for discharging compressed gas at high speed. Preferred Features: The outlet opening is formed by a peripheral wall having an outermost end forming an outlet edge (54). The annular gap is arranged in the region of the outlet edge. Control devices and/or compressed gas sources are provided to independently adjust the pressure of the compressed gas fed to the annular gap and the pressure opening into a mixing chamber (40).

Abstract (de)

Zweistoffzerstäubungsdüse zum Versprühen einer Flüssigkeit unter Zuhilfenahme eines Druckgases. Die Erfindung betrifft eine Zweistoffzerstäubungsdüse zum Versprühen einer Flüssigkeit unter Zuhilfenahme eines Druckgases mit einer Mischkammer, einem in die Mischkammer mündenden Flüssigkeitseinlass, einem in die Mischkammer mündenden Druckgaseinlass und einer Austrittsöffnung stromabwärts der Mischkammer. Erfindungsgemäß ist ein die Austrittsöffnung umgebender Ringspalt zum Austreten von Druckgas mit hoher Geschwindigkeit vorgesehen. Verwendung z.B. für die Rauchgasreinigung.
