Product Overview
Circular chimney silencer, also known as cylindrical stack muffler, is a professional noise reduction device specially designed for industrial chimneys, flues and exhaust stacks. Adopting circular streamlined structure, multi-layer composite sound absorption and sound insulation design, it effectively eliminates high-decibel airflow noise generated by flue gas exhaust, ventilation fans, boilers and industrial exhaust equipment. With compact round appearance, stable structure and high temperature resistance, it perfectly matches circular chimney pipelines, widely applied in chemical plants, power plants, heating stations, factories and other industrial noise control projects.
Core Product Features
1. Optimized Circular Streamlined StructureCylindrical round design fits seamlessly with circular chimney pipes, avoidsairflow turbulence and secondary noise, small wind resistance, no influence onnormal exhaust and smoke discharge efficiency.
2. Efficient Multi-Stage Noise Reduction SystemInternal filled with high-density flame-retardant sound-absorbing media,equipped with perforated noise elimination partitions. It absorbs low, mediumand high frequency airflow noise simultaneously, with stable noise reductioneffect up to 15-40dB.
3. High Temperature & Corrosion Resistant ShellOuter shell made of galvanized steel or stainless steel optional, anti-rust, acidand alkali resistant, long service life under high-temperature flue gas workingenvironment.
4. Safe Flame Retardant Internal FillerSound absorption material reaches flame retardant standard, no deformationor powder falling under long-term high temperature operation, reliable forboiler and high-temperature exhaust pipelines.
5. Customized Size & Connection CaliberSupport customized diameter, length, flange connection size according tocustomer's chimney pipe parameters, convenient for on-site welding andinstallation.
6. Low Maintenance DesignIntegrated sealed structure, dust-proof and waterproof, no frequentreplacement of internal filler, greatly reducing later maintenance cost.
