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 BoilersSteam for thermal equipmentEmissionThe noise emitted can reach up to 130 decibels.
ThreeFeatures
Pipe mufflers (noise suppressors) are primarily used for effectively silencing steam emissions from thermal equipment such as boilers and steam turbines in power generation departments. They are also extensively employed in the boiler steam emissions and other gas emission silencing in industries such as oil, chemicals, metallurgy, and textiles..A muffler is a device that blocks sound from spreading while allowing airflow to pass through.Significant measures for reducing steam exhaust dynamic noise. To assess the quality of an exhaust muffler, consider the following three main aspects:
The noise reduction of the pipeline silencer meets the requirements of the "Hygienic Standards for Noise in Industrial Enterprises."
2. Pipe silencers are adaptable to a wide frequency spectrum of low to medium frequencies and high temperatures and pressures.
3. The pipeline muffler features reasonable structural dimensions, low cost, and long service life.
The steam from boilers in the power generation department is not only high temperature and high pressure but also has a wide frequency bandwidth. Simply relying on small-hole soundproofing is not sufficient. The Aulivac Steam Exhaust Silencer is designed based on the composite noise reduction principle of resistance, spray, and damping, offering large noise reduction capacity, a wide frequency bandwidth, and targeted design (for various boiler and pressure vessel pipeline exhausts such as low-pressure, medium-pressure, sub-high-pressure, high-pressure, ultra-high-pressure, sub-critical, and super-critical parameters), with the advantages of being made of stainless steel (1Cr18Ni9Ti, 12Cr1MoV) and easy to install.
Four,Principle
Boiler exhaust silencers are manufactured based on the micro-perforated plate noise reduction principle. The steam emissions from power plant boilers typically have high velocities, and high velocities significantly affect noise reduction in small holes. Therefore, we need to control the flow first, then the steam that has been controlled enters the expansion chamber for further pressure reduction and noise reduction. After the steam is subjected to 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 octave band is reduced, and the sound pressure level frequency is pushed to above 20,000Hz, significantly reducing 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 spectrum characteristics of the residual noise emitted by the pressure reduction body to effectively absorb the remaining noise. After installation according to specifications, the total noise reduction should reach 30-60 decibels, meeting the required standards.
FiveSelection
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.SureExcellent sound-dampening effect.
