摘要

PURPOSE:To prevent any product and dust from adhering to and being deposited on an internal wall in a duct owing to reaction gas and automatically remove them even if they are deposited by providing a self cleaning blade rotatable along the internal wall in the duct. CONSTITUTION:A self cleaning blade 4 is rotatably disposed along an internal wall of a duct. When any matter such as reaction products produced owing to exhaust gas adheres to and is deposited on the duct internal wall, the adhering matter is hereby automatically removed by rotating the blade 4 by a driving motor 6. Further, adhesion of such matter is prevented by rotating the self cleaning blade 4 at all times. Thus, cleaning is ensured with a piping kept connected without requiring disconnection of the piping for cleaning.
