NOISE SUPPRESSOR OF TEXTILE WASTE TREATMENT SYSTEM Russian patent published in 2007 - IPC F01N1/00 

FIELD: mechanical engineering; textile industry; noise silencers.

SUBSTANCE: proposed noise suppressor contains housing with in form of cylindrical shell, coaxial intake and outlet branch pipes and resonance insert in form solid of revolution installed coaxially to housing with formation of ring clearance. Said resonance insert made in from of solid of revolution consists of central cylindrical shell, radius R₁ and two conical shells, length H_k secured at edges of cylindrical shell. Perforated disks, radius R₂ are rigidly secured to conical shells from side of their free planes, and element is installed in middle of resonance insert to increase rigidity of resonance insert, said element is made in form of solid disk. Resonance insert is secured in housing by means of attachment elements made in form of at least one ring with holes. Housing in lined from inside, and resonance insert from outside, with noise absorbing material of thickness h₁ and h₂, respectively.

EFFECT: improved efficiency of noise damping.
