II. Application
For use with: Steam Boilers &Steam related to thermal equipmentEmissionThe noise emitted can reach up to 130 decibels.
Three,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 boiler steam emissions and other gas exhaust silencing of industries such as oil, chemicals, metallurgy, and textiles..A muffler is a device that blocks sound transmission while allowing air flow.Key measures for reducing steam exhaust dynamic noiseTo assess the quality of an exhaust muffler, the following three aspects are mainly considered:
The noise attenuation of the pipeline muffler meets the requirements of the "Industrial Enterprise Noise Hygiene Standard."
2. Pipe silencers are adaptable to a wide frequency spectrum, including low and medium frequencies, as well as high temperatures and pressures.
3. The pipeline muffler features 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 soundproofing 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, wide frequency range adaptation, and targeted design (for various boiler and pressure vessel pipeline exhaust emissions, including parameters such as low pressure, medium pressure, sub-high pressure, high pressure, ultra-high pressure, subcritical, and supercritical), with the advantages of easy manufacturing and installation of the silencer using stainless steel (1Cr18Ni9Ti, 12Cr1MoV).
FourPrinciple
Boiler exhaust mufflers are manufactured based on the micro-perforated plate noise reduction principle. Power plant boiler steam emissions typically have high flow rates, and high flow rates have a significant impact on the noise reduction of small holes. Therefore, we first need to control the flow. After the steam passes through the initial flow control, it then enters 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 hole diameters. After ejection, the sound power in various frequency bands has been reduced, and the sound pressure level frequencies are pushed above 20,000 Hz, significantly reducing the noise. However, secondary noise at certain frequencies still requires additional noise reduction. We install a resistive sound-absorbing cotton structure outside the expansion chamber, which is designed based on the frequency spectrum characteristics of the remaining noise emitted by the depressurization 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 muffler is meticulously designed according to the customer's emission targets and requirements. Consequently, only products that match the emission targets and parameters are eligible.AlrightExcellent sound-dampening effect.
