Pipe silencers (mufflers) are primarily used for effectively reducing noise from steam emissions in thermal equipment such as boilers and steam turbines in power generation departments. They are also extensively employed in the steam emissions of boilers and other gas exhausts in industries like oil, chemicals, metallurgy, and textiles. A silencer is a device that prevents sound from propagating while allowing airflow, serving as a crucial measure for eliminating the dynamic noise of steam emissions. When assessing the quality of steam exhaust silencers, three main aspects should be considered:
The noise reduction of the pipeline silencer meets the requirements of the "Noise Hygiene Standards for Industrial Enterprises."
2. The adaptability of pipeline silencers (i.e., suitable for low to mid-frequency bandwidth and high temperature and pressure conditions).
3. Structural performance of pipe silencers (Reasonable dimensions, low cost, long lifespan, etc.).
Boiler steam in the power generation department is not only high temperature and high pressure but also has a wide emission frequency range. Simply relying on small hole sound absorption is not sufficient. The Zhuli Exhaust Sound Absorber is developed based on the composite noise reduction principle of resistance, jet, and obstruction, featuring large noise reduction capacity, wide frequency range adaptation, and targeted design (for various boilers and pressure vessel pipelines with parameters such as low pressure, medium pressure, sub-high pressure, high pressure, ultra-high pressure, subcritical, and supercritical), with the advantages of being made of stainless steel (1Cr18Ni9Ti, 12Cr1MoV) and easy to install.
