II. Usage
For: Steam Boilers &Steam related to thermal equipmentEmissionThe noise emitted can reach up to 130 decibels.
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 widely employed in the steam emissions and noise reduction of gases in industries such as oil, chemical, metallurgy, and textile, among others..A muffler is a device that prevents sound from spreading while allowing air flow through.Significant measures for reducing the dynamic noise of steam exhaustTo 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 mufflers are adaptable to a wide frequency spectrum of low to medium frequencies, as well as high temperatures and pressures.
3. Pipe silencers feature reasonable structural dimensions, low cost, and long service life.
Boiler steam in the power generation department is not only high temperature and high pressure but also has a wide frequency band of emissions. Simply relying on small hole sound absorption is not sufficient. The Zuli Exhaust Sound Absorber is developed based on the composite noise reduction principle of resistance, injection, and impedance. It features large noise reduction capacity, a wide frequency band, and targeted design (for various boiler and 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.
Four,Principle
Boiler exhaust silencers are manufactured based on the micro-perforated plate noise reduction principle. The steam exhaust from power plant boilers typically has a high velocity, which greatly affects the noise reduction of small apertures. Therefore, we need to control the flow first, and then the steam enters the expansion chamber after one-time flow control, further reducing pressure and noise. After the steam is减压to a large volume, it forms low-pressure steam喷射。In this process, the airflow is ejected through small-diameter holes. After ejection, the sound power of various frequency bands is reduced, and the frequency of sound pressure level is pushed up to over 20000Hz, 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 according to 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 as required, the total noise reduction should reach 30-60 decibels, meeting the required standard.
FiveSelection
The mufflers are meticulously designed according to the user's emission targets and requirements. Consequently, only products that match the emission targets and parameters are eligible.SureExcellent sound-dampening effect.
