Product Details: As an important noise source in industrial production, the blow-off noise is characterized by high noise intensity, wide spectrum, wide pollution hazard range, and high temperature and high-speed airflow emissions. The blow-off noise is generally generated by the instability of high-speed airflow flow. The blow-off silencer is an effective silencer specifically designed to reduce and control blow-off noise. It can be used to reduce the high-intensity noise generated by high-pressure, high-temperature and high-speed blow-off in industrial sectors, such as chemical, petroleum, llurgy and power. They can be mainly divided into throttling and reducing type blow-off silencers, micropore injection blow-off silencers, throttling and reducing & micropore injection composite silencers, and porous dissipative blow-off silencers.
