Section 3: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 blocks sound transmission while allowing air flow through.Significant 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, including low and medium frequencies, as well as 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 frequency range of emissions. Simply relying on small hole noise reduction is insufficient. The Zuli Exhaust Steam Silencer is developed based on the composite noise reduction principle of resistance, jet, and obstruction, featuring large noise reduction capacity, wide frequency adaptability, and targeted design (for various boiler and pressure vessel pipeline exhaust emissions, including parameters such as low, medium, sub-high, high, ultra-high, subcritical, and supercritical pressures), with the advantages of being made of stainless steel (1Cr18Ni9Ti, 12Cr1MoV) and easy to install and fit.
FourPrinciple
Boiler exhaust mufflers are manufactured based on the micro-perforated plate noise reduction principle. The steam discharge from power plant boilers typically has high flow rates, which significantly affect the noise reduction of small holes. Therefore, we first need to control the flow, and then the steam, after passing through the initial flow control, enters the expansion chamber for further pressure reduction and noise reduction. After the steam is subjected to 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 frequencies are pushed up to above 20,000Hz, greatly diminishing 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 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 required standards.
