Section 3: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 silencing and other gas exhaust emissions in industries such as oil, chemicals, metallurgy, and textiles.A muffler is a device that prevents sound from spreading while allowing air flow through.Key measures for reducing the dynamic noise of steam exhaustTo evaluate the quality of an exhaust muffler, consider the following three main aspects:
The noise reduction of the pipeline muffler meets the requirements of the "Noise Sanitation Standard for Industrial Enterprises."
2. Pipeline silencers are adaptable to a wide bandwidth of low to mid-frequency spectrums and high temperatures and pressures.
3. The pipeline silencer features 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 emission band. 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, spray, and obstruction, featuring large noise reduction capacity, broad frequency adaptation, and targeted design (for various boilers and pressure vessel pipeline exhaust discharge with parameters such as low, medium, sub-high, high, ultra-high, subcritical, and supercritical pressures), and the silencer is made of stainless steel (1Cr18Ni9Ti, 12Cr1MoV) with the advantages of convenient manufacturing and installation.
FourPrinciple
Boiler exhaust mufflers are manufactured based on the micro-perforated plate noise reduction principle. The steam排放 from power plant boilers typically has high flow rates, which significantly affect the noise reduction of small holes. Therefore, we first control the flow, and then the steam enters the expansion chamber after passing through the initial flow control, where it is further pressure-reduced and noise-suppressed. After the steam is pressure-reduced in a large volume, it forms low-pressure steam that is ejected. During this process, the airflow is ejected through small diameter holes. After ejection, the sound power in various frequency bands is reduced, and the sound pressure level frequency is 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 installation according to specifications, the total noise reduction should reach 30-60 decibels, meeting the required standards.
Five.Selection
The muffler is meticulously designed according to the user's emission targets and requirements. Consequently, only products that match the emission targets and parameters can be approved.SureExcellent sound-dampening effect.
