Device for aeration by sudden discharge of compressed air with improved ejection duct

摘要

The rapid air discharger for cleaning a cement works has an air accumulation reservoir (4) connected to a discharge duct (3), and an outlet pipe (5). The area (C) of the section of the outlet pipe at its distal end is larger than the area (A) of the duct input section situated adjacent to the air flow control. The outlet pipe can have a convergent-divergent section.
