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 silencing and other gas exhausts in industries like oil, chemical, metallurgy, and textiles.A muffler is a device that prevents sound from spreading while allowing airflow to pass through.Significant measures for reducing the dynamic noise of steam exhaustTo assess the quality of an exhaust muffler, the following three aspects are primarily considered:
The noise reduction of the pipeline muffler 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, as well as high temperatures and pressures.
3. Pipe silencers feature reasonable structural dimensions, low cost, and long lifespan.
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 soundproofing is insufficient. The Zhuli Exhaust Steam Soundproofing Device is developed based on the composite noise reduction principle of resistance, injection, and impedance. It features large noise reduction capacity, wide frequency band adaptation, and targeted design (for various boiler and pressure vessel pipeline exhaust discharge 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.
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, which significantly impact noise reduction in small apertures. Therefore, we first control the flow rate, and then the steam enters the expansion chamber after passing through a flow control stage, where it is further pressurized to reduce noise. After the steam is pressurized in a large volume, it forms low-pressure steam that is ejected. During this process, the airflow is ejected through small diameter apertures. The sound power across various frequency bands is reduced after ejection, and the sound pressure level frequencies are pushed above 20,000 Hz, greatly diminishing the noise. However, secondary noise at certain frequencies still requires further noise reduction. We add a resistive sound-absorbing 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 as required, the total noise reduction should reach 30-60 decibels, meeting the requirements.
FiveSelection
The mufflers are meticulously designed according to the customer's emission targets and requirements. Consequently, only products that match the emission targets and parameters are eligible.SureExcellent sound-dampening effect.
