DEORDORIZING SYSTEM FOR DRAIN PIPE

摘要

PURPOSE: A deodorizing system for a drain pipe is provided to effectively remove offensive odors from a drain pipe even if the amount of sewage or rainwater is sharply increased. CONSTITUTION: A deodorizing system(100) for a drain pipe comprises deodorizing units(140) and air current cutoff assemblies. The deodorizing units are installed on the top of a drain pipe(10) at uniform intervals and collect and remove offensive odors. The air current cutoff assemblies are installed on the inner top end of the drain pipe at uniform intervals and form negative pressure inside the drain pipe.
