The paper presents the results of investigations on acoustic coagulation of industrial gases carried out on pilot installation in a selected industrial plant.

By submitting preliminary combustion gases of coal dust to the action of powerful acoustic field the remarkable increase of efficiency of dust extracting and particularly of small dust particles by means of cyclone has been obtained. As the generator of powerful acoustic fields there has been used the dynamic sirene described in the paper [1].


In der vorliegenden Arbeit werden die Ergebnisse von Untersuchungen über die Koagulation von Industrieabgasen vorgestellt, die an einer Pilotanlage in einem ausgewählten Betrieb durchgeführt wurden.

Durch Beschallung von Verbrennungsabgasen mit einem starken Schallfeld wurde eine deutliche Verbesserung der Staubabscheidung - besonders kleiner Staubpartikel - durch einen Zyklon beobachtet. Als Schallerzeuger wurde die in [1] beschriebene dynamische Sirene benutzt.


On présente les résultats d'une recherche sur la coagulation acoustique des gaz industriels. Les expériences ont été effectuées dans une installation pilote équipant une usine sélectionnée.

En soumettant préliminairement des gaz de combustion à l'action d'un puissant champ acoustique, on a constaté une nette augmentation d'efficacité du dépoussiérage, notamment en ce qui concernait les particules les plus fines. Le générateur acoustique était une sirène dynamique qui a été décrite récemment dans Acustica.
