Self-silencing chimney for rto

Abstract

The utility model discloses a self -noise formula chimney for RTO, specifically at RTO chimney field, chimney includes from top to bottom in proper order set up upper pipe, silencer pipe and lower pipe, and upper pipe and lower pipe all are arranged as funnel shape, the inside installation of silencer pipe has the acoustic lining of equidistance distribution of several layers, and the intercalation of several layers acoustic lining has the pipeline assembly, the inside installation of upper pipe has the upper flow guide spare of pipeline assembly intercommunication, the inside installation of lower pipe has the lower flow guide spare of pipeline assembly intercommunication. The utility model discloses through porous sound absorption board, perforated plate and multi -chamber structure cover broadband noise, utilize pipeline through -hole shunt and concentric circle sound -proof mechanism simultaneously and prolong the flue gas and sound wave propagation path, enhance the sound energy absorption and resonance cancellation effect.
