II. Usage
For Use With: Steam Boilers &Steam related to thermal equipmentEmissionThe noise emitted can reach up to 130 decibels.
III.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 from boilers and other gas exhausts in industries such as oil, chemicals, metallurgy, and textiles..A muffler is a device that blocks sound from spreading while allowing airflow to pass through.Significant Measures for Reducing Steam Emission Dynamic NoiseTo assess the quality of an exhaust muffler, consider the following three main aspects:
The noise reduction capacity of the pipeline muffler meets the requirements of the "Noise Hygiene Standard for Industrial Enterprises."
2. Pipe silencers are adaptable to a broad frequency spectrum of low to medium frequencies, as well as high temperatures and pressures.
3. The structure and 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 emission frequency range. Simply relying on small hole noise reduction is insufficient. The Zhuli Exhaust Noise Attenuator 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, pressure vessel pipeline exhaust venting, 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 install.
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 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 hole diameters. After ejection, the sound power of each harmonic band 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 install a resistive sound-absorbing 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 residual noise. After the user installs it as required, the total noise reduction should reach 30-60 decibels, meeting the requirements.
