II. Usage
For use with: Steam BoilersSteam related to thermal equipmentEmissionThe noise emitted can reach up to 130 decibels.
Three,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 prevents sound from spreading while allowing airflow to pass through.Key measures for reducing steam exhaust dynamic noiseTo assess the quality of an exhaust muffler, consider the following three main aspects:
The noise reduction efficiency of our pipeline silencers meets the requirements of the "Industrial Enterprise Noise Hygiene Standard."
2. Pipe mufflers are adaptable to a wide frequency spectrum, including low and medium frequencies, as well as high temperatures and pressures.
3. Pipe mufflers 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 band. Simply relying on small hole soundproofing is insufficient. The Assistive Exhaust Sound Absorber is developed based on the composite noise reduction principle of resistance, spray, and impedance. It features large noise reduction capacity, wide frequency band adaptation, and targeted design (for various boiler and pressure vessel pipeline exhausts, including parameters such as low pressure, medium pressure, sub-high pressure, high pressure, ultra-high pressure, subcritical, and supercritical). The sound-damping sleeve is made of stainless steel (1Cr18Ni9Ti, 12Cr1MoV) and is easy to manufacture and install.
FourPrinciple
Boiler exhaust silencers are manufactured based on the micro-perforated plate noise reduction principle. The steam emission from power plant boilers usually has high flow rates, which significantly affect the noise reduction of small apertures. Therefore, we need to control the flow first, and then the steam, after being controlled, enters the expansion chamber for further pressure reduction and noise reduction. After the steam is subjected to a large volume of pressure reduction, it forms low-pressure steam that is ejected. During this process, the airflow is ejected through small diameter apertures. After ejection, the sound power in various frequency bands is reduced, and the sound pressure level frequency is pushed up to above 20,000 Hz, significantly reducing the noise. However, secondary noise at certain frequencies still requires further noise reduction. We add a resistive absorbent cotton structure outside the expansion chamber, which is designed according to the frequency spectrum characteristics of the residual 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.
FiveSelection
The muffler is meticulously designed according to the user's emission target and requirements. Therefore, only products that match the emission target and parameters are eligible.AlrightExcellent sound-dampening effect.
