Section 3:Features
Pipe silencers (mufflers) are primarily used for effectively silencing steam emissions from thermal equipment such as boilers and steam turbines in power generation departments. They are also widely employed in the steam emissions and noise reduction of gases in industries such as oil, chemicals, metallurgy, and textiles..A muffler is a device that blocks sound transmission while allowing airflow to pass through.Significant measures for reducing the dynamic noise of steam exhaust. To evaluate the quality of an exhaust silencer, consider the following three main aspects:
The noise reduction of the pipeline muffler meets the requirements of the "Noise Hygiene Standards for Industrial Enterprises."
2. Pipeline silencers are adaptable to a wide frequency spectrum, including low and medium frequencies, as well as high temperatures and pressures.
3. Pipe silencers feature reasonable structural dimensions, low cost, and long lifespan.
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 insufficient. The Aulii Exhaust Steam Muffler is developed based on the composite noise reduction principle of resistance, injection, and damping, featuring large noise reduction capacity, wide frequency adaptability, and targeted design (for various boiler and pressure vessel pipeline exhaust emissions, including low-pressure, medium-pressure, sub-high-pressure, high-pressure, ultra-high-pressure, subcritical, and supercritical parameters), with the advantages of being made of stainless steel (1Cr18Ni9Ti, 12Cr1MoV) and easy to install.
FourPrinciple
Boiler exhaust silencers are manufactured based on the micro-perforated plate noise reduction principle. The steam排放 from power plant boilers typically has high flow rates, which significantly affect the noise reduction of small holes. Therefore, we first control the flow, and then the steam enters the expansion chamber after passing through the initial flow control, where it further reduces pressure and noise. After the steam is depressurized in a large volume, it forms low-pressure steam that is ejected. During this process, the airflow is ejected through small orifices. After ejection, the sound power in various frequency bands is reduced, and the sound pressure level frequency is pushed up to above 20,000Hz, greatly diminishing the noise. However, secondary noise at certain frequencies still requires additional noise reduction. We install a resistive acoustic cotton structure outside the expansion chamber, which is designed based on the frequency spectrum characteristics of the remaining noise emitted by the depressurization body to effectively absorb the residual noise. After the user installs it according to specifications, the total noise reduction should reach 30-60 decibels, meeting the required standards.
FiveSelection
The muffler is meticulously designed according to the user's emission targets and requirements. Therefore, only products that match the emission targets and parameters are eligible.SureExcellent sound-dampening effect.
