Abstract

Die Erfindung beinhaltet Verfahren zum Erzeugen eines Aerosols, wobei zwei Gasströme (6,6a) im Gegenstrom in einen abgegrenzten Mischraum (3) eingeleitet werden und in dem Mischraum mit feinen Partikeln beladen werden und das erzeugte Aerosol aus dem Mischraum über einen Auslass (7) abgeführt wird. Weiter beinhaltet die Erfindung eine Vorrichtung zum Erzeugen eines Aerosols mit einem Mischraum, bei der der Mischraum mindestens zwei einander gegengerichtete Gaseinlässe aufweist.The invention includes methods for generating an aerosol, wherein two gas streams (6, 6a) are introduced countercurrently into a delimited mixing chamber (3) and are loaded with fine particles in the mixing chamber and the aerosol generated is conveyed out of the mixing chamber via an outlet (7). is dissipated. Furthermore, the invention includes a device for producing an aerosol with a mixing space, wherein the mixing space has at least two mutually opposing gas inlets.
