ThreeFeatures
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 extensively applied in the steam emissions and noise reduction of gases in industries such as oil, chemical, metallurgy, and textile.A muffler is a device that prevents sound from propagating while allowing airflow through.Significant measures for reducing the dynamic noise of steam exhaust. Assessing the quality of exhaust mufflers primarily involves considering the following three 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 silencer 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, which cannot be effectively muffled by simply using small holes. The Zuli Exhaust Muffler is developed based on the composite noise reduction principle of resistance, injection, and obstruction, featuring large noise reduction capacity, wide frequency range adaptation, 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.
Four,Principle
Boiler exhaust silencers are manufactured based on the micro-perforated plate noise reduction principle. Power plant boiler steam emissions generally have high flow rates, and high flow rates significantly affect the noise reduction of small holes. Therefore, we need to control the flow first, and then the steam that has been controlled flows into 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 hole diameters. After ejection, the sound power in each octave band is reduced, and the sound pressure level frequency is pushed above 20,000Hz, greatly reducing the noise. However, secondary noise at certain frequencies still requires further noise reduction. We install a resistive acoustic cotton structure outside the expansion chamber, which is designed based on 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 standards.
