Product Details
I. Definition
Pipe muffler (muffler) products mainlyEffective noise reduction for steam emissions from boilers, steam turbines, and other thermal equipment in power generation departments。
II. Usage
For use with: Steam BoilersSteam related to thermal equipmentEmissionThe noise emitted can reach up to 130 decibels.
III.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 boiler steam emissions and other gas exhaust silencing in industries like oil, chemicals, metallurgy, and textiles..A muffler is a device that prevents sound from spreading while allowing air flow.Significant measures for reducing the dynamic noise of steam exhaustWhen assessing the quality of an exhaust silencer, 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. Pipeline silencers are adaptable to a wide bandwidth of low to mid-frequency spectra and 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 range of emissions. Simply relying on small-hole sound absorption is insufficient. The Zuli Exhaust Sound Absorber is developed based on the composite noise reduction principle of resistance, jet, and damping, featuring large noise reduction capacity, wide frequency adaptability, and targeted design (for various boiler and pressure vessel pipeline exhaust emissions at parameters such as low, medium, sub-high, high, ultra-high, subcritical, and supercritical pressures), with the advantages of easy manufacturing and installation of the noise reduction tube made of stainless steel (1Cr18Ni9Ti, 12Cr1MoV).
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 that has been controlled flows into the expansion chamber for further pressure reduction and noise reduction. After the steam is depressurized in a large volume, it forms low-pressure steam that is ejected. During this process, the airflow is ejected through small orifices. 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 depressurization 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.
FiveSelection
The mufflers are carefully designed according to the user's emission targets and requirements. Consequently, only products that match the emission targets and parameters can be obtained.GoodExcellent sound-dampening effect.
