Product Details
I. Definition
Pipe muffler (muffler) products mainlyEffective noise reduction for steam emissions from boilers, steam turbines, and other thermal equipment in power generation departments。
II. Usage
For use with: Steam Boilers &Steam related to thermal equipmentEmissionThe noise emitted can reach up to 130 decibels.
III.Features
Pipe silencers (noise dampers) are primarily used for effectively muffling 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 suppression of gases in industries such as oil, chemical, metallurgy, and textiles..A muffler is a device that blocks sound transmission while allowing air flow.Significant measures for reducing the dynamic noise of steam exhaustTo evaluate the quality of an exhaust muffler, consider the following three main aspects:
The noise reduction of our pipeline silencers meets the requirements of the "Noise Hygiene Standards for Industrial Enterprises."
2. Pipe silencers are adaptable to low and medium frequency spectrums, wide bandwidths, and high temperatures and pressures.
3. The pipeline silencer features reasonable structural dimensions, low cost, and long service life.
Boiler steam in the power generation department is not only high temperature and high pressure but also has a wide frequency emission range. Simply relying on small hole noise reduction is insufficient. The Auliu exhaust steam silencer is developed based on the composite noise reduction principle of resistance, injection, and damping, featuring large noise reduction capacity, wide frequency adaptation, and targeted design (for various boiler and pressure vessel pipeline exhaust venting, including parameters such as low, medium, sub-high, high, ultra-high, subcritical, and supercritical pressures). The silencer is made of stainless steel (1Cr18Ni9Ti, 12Cr1MoV) for easy manufacturing and installation.
FourPrinciple
Boiler exhaust silencers are manufactured based on the micro-perforated plate noise reduction principle. Power plant boiler steam emissions typically have high flow rates, and high flow rates significantly affect the noise reduction of small holes. Therefore, we need to control the flow first, and then the steam after the first flow control enters the expansion chamber for further pressure reduction and noise reduction. After the steam is subjected to a large volume pressure reduction, it forms low-pressure steam emissions. During this process, the airflow is ejected through small diameter holes. After ejection, the sound power in each frequency band is reduced, and the sound pressure level frequency is pushed up to above 20,000Hz, greatly reducing the noise. However, secondary noise at certain frequencies still requires further noise reduction. We add a resistive sound-absorbing cotton structure outside the expansion chamber, which is designed based on the frequency spectrum characteristics of the remaining noise emitted by the pressure reduction body, to effectively absorb the remaining noise. After the user installs it according to specifications, the total noise reduction should reach 30-60 decibels, meeting the requirements.
FiveSelect Model
The mufflers are meticulously designed according to the user's emission targets and requirements. Consequently, only products that match the emission targets and parameters are eligible.AlrightExcellent soundproofing effect.
