III.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 other gases in industries such as oil, chemical, metallurgy, and textile..A muffler is a device that blocks sound from spreading while allowing airflow to pass through.Key measures for reducing steam exhaust dynamic noise. Assessing the quality of exhaust silencers primarily involves considering the following three aspects:
The noise reduction of the pipeline muffler meets the requirements of the "Noise Hygiene Standards for Industrial Enterprises."
2. Pipe silencers are adaptable to low to medium frequency bandwidth and high-temperature, high-pressure conditions.
3. Pipe silencers feature reasonable structural dimensions, low cost, and long lifespan.
The steam from boilers 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 sound attenuation is not sufficient. The Assistive Exhaust Sound Attenuator is developed based on the composite noise attenuation principle of resistance, injection, and blocking, featuring large noise attenuation, broad frequency adaptation, and targeted design (for various boilers and pressure vessel pipeline exhaust discharge, including parameters such as low pressure, medium pressure, sub-high pressure, high pressure, ultra-high pressure, sub-critical, and super-critical). The noise attenuation tube is made of stainless steel (1Cr18Ni9Ti, 12Cr1MoV) for easy installation.
FourPrinciple
Boiler exhaust silencers are manufactured based on the micro-perforated plate noise reduction principle. The steam排放 from power plant boilers typically has high flow rates, and high flow rates have a significant impact on the noise reduction of small holes. Therefore, we need to control the flow first, and then the steam that has been controlled enters the expansion chamber for further pressure reduction and noise reduction. 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 orifices. After ejection, the sound power in various frequency bands is reduced, and the sound pressure level frequency is pushed up to above 20,000Hz, 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 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 required standard.
