Section 3:Features
Pipe mufflers (silencers) 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 silencing and other gas exhausts in industries like oil, chemical, metallurgy, and textiles..A muffler is a device that blocks sound from spreading while allowing air flow 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 of the pipeline silencer meets the requirements of the "Noise Hygiene Standards for Industrial Enterprises."
2. Pipe silencers are adaptable to a wide frequency spectrum of low to medium frequencies and high temperatures and pressures.
3. The structural dimensions of the pipeline silencers are reasonable, cost-effective, and have a 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. Simply relying on small hole sound absorption is not sufficient. The Assistive Exhaust Sound Attenuator is developed based on the composite noise reduction principle of resistance, injection, and damping. It features large noise reduction capacity, wide frequency adaptability, and targeted design (for various boiler and pressure vessel pipeline exhaust emissions, including parameters such as low pressure, medium pressure, sub-high pressure, high pressure, ultra-high pressure, subcritical, and supercritical). The noise reduction tube is made of stainless steel (1Cr18Ni9Ti, 12Cr1MoV) and is easy to manufacture and install.
IV.Principle
Boiler exhaust silencers are manufactured based on the micro-perforated plate noise reduction principle. Power plant boiler steam emissions typically have high velocities, and high velocities have a significant impact on the noise reduction of small holes. Therefore, we first need to control the flow. After the steam passes through the initial flow control, it then enters the expansion chamber for further pressure reduction and noise reduction. After the steam undergoes large-volume pressure reduction, it forms low-pressure steam that is ejected. During this process, the airflow is ejected through small hole diameters. After ejection, the sound power across all frequency bands has been reduced, and the sound pressure level frequencies are pushed above 20,000 Hz, greatly diminishing 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 residual noise emitted by the pressure-reducing body to effectively absorb the remaining noise. After the user installs it as required, the total noise reduction should reach 30-60 decibels, meeting the specified requirements.
FiveSelection
The mufflers are meticulously designed according to the customer's emission targets and requirements. Consequently, only products that match the emission targets and parameters are eligible.GreatExcellent soundproofing effect.
