Product Details
I. Definition
Pipe muffler (muffler) products mainlyEffective noise reduction for steam emissions from thermal equipment such as boilers and steam turbines in power generation departments。
II. Usage
For use with: Steam Boilers &Steam related to thermal equipmentEmissionThe noise emitted can reach up to 130 decibels.
Three,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 reduction of other gases in industries such as oil, chemical, metallurgy, and textile, as well as for boiler steam emissions..A muffler is a device that blocks sound transmission while allowing air flow through.Significant measures for reducing the dynamic noise of steam exhaustTo assess the quality of an exhaust muffler, consider the following three main aspects:
The noise attenuation of the pipeline muffler meets the requirements of the "Noise Hygiene Standards for Industrial Enterprises."
2. Pipe mufflers are adaptable to a broad frequency spectrum of low to medium frequencies, as well as high temperatures and pressures.
3. Pipe silencers feature 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 emission frequency range. Relying solely on small hole soundproofing is insufficient. The Zhuli exhaust steam silencer is developed based on the composite noise reduction principle of resistance, spray, and damping. It features large noise reduction capacity, wide frequency range adaptation, and targeted design (for various boilers and pressure vessel pipelines with parameters such as low, medium, sub-high, high, ultra-high, subcritical, and supercritical pressures), with the advantages of easy manufacturing and installation using stainless steel (1Cr18Ni9Ti, 12Cr1MoV) for the silencer.
FourPrinciple
Boiler exhaust silencers are manufactured based on the micro-perforated plate noise reduction principle. The steam emission from power plant boilers typically has high velocity, which significantly affects the noise reduction of small holes. Therefore, we first control the flow, and then the steam enters the expansion chamber after the first flow control, where it is further pressure-reduced and noise-reduced. After the steam undergoes a large volume pressure reduction, it forms low-pressure steam that is ejected. During this process, the airflow is ejected through small holes. After ejection, the sound power across various frequency bands has been reduced, and the sound pressure level frequencies are pushed up to above 20,000Hz, greatly diminishing the noise. However, secondary noise at certain frequencies still requires further reduction. We install a resistive sound-absorbing cotton structure outside the expansion chamber, which is designed based on the spectrum characteristics of the remaining noise emitted by the pressure-reducing body to effectively absorb the residual noise. After the user installs it as required, the total noise reduction should reach 30-60 decibels, meeting the required standards.
Five,Selection
The mufflers are meticulously designed according to the user's emission targets and requirements; accordingly, only products that match the emission targets and parameters are eligible.GoodExcellent sound-dampening effect.
