Abstract

Perfectionnement aux traitements des gaz. Un conduit de gaz 16 aboutit à un précipitateur électrostatique 10 en faisant un certain angle avec la direction de circulation des gaz dans ce dernier. Des éléments saillants 38 sont prévus dans le conduit, près de l'entrée 20 du précipitateur afin d'augmenter l'épaisseur de la zone turbulente de la couche limite des gaz; ceci a pour effet de solliciter les gaz vers les régions d'amont de l'entrée 20 et de favoriser ainsi une distribution uniforme de ceux-ci le long de cette dernière. Application aux techniques de dépoussiérage des gaz.
