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: Steam BoilersSteam for thermal equipmentEmissionThe noise emitted can reach up to 130 decibels.
Three,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 blocks sound transmission while allowing air flow.Significant measures for reducing the dynamic noise of steam exhaust. To assess 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 Hygiene Standards for Industrial Enterprises."
2. Pipe mufflers can accommodate low to mid-frequency bandwidth and high temperatures and pressures.
3. The structure and dimensions of the pipeline silencers 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 frequency range of emissions. Simply using small hole soundproofing is insufficient. The Zuli 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 range adaptation, and targeted design (for various boilers and pressure vessel pipelines with parameters such as low pressure, medium pressure, sub-high pressure, high pressure, ultra-high pressure, subcritical, and supercritical), with the advantages of being made of stainless steel (1Cr18Ni9Ti, 12Cr1MoV) and easy to install and assemble.
FourPrinciple
Boiler exhaust silencers are manufactured based on the micro-perforated plate noise reduction principle. The steam排放 from power plant boilers generally has a high flow rate, and a high flow rate significantly affects the noise reduction of small holes. Therefore, we first control the flow, and then the steam that has been controlled enters the expansion chamber for further pressure reduction and noise reduction. 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 holes. After ejection, the sound power in each harmonic frequency band has been reduced, and the sound pressure level frequency is pushed up to above 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 remaining 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.
Five.Selection
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.
