Product Details
I. Definition
Pipe silencers (mufflers) are primarily used for effective noise reduction of steam emissions from thermal equipment such as boilers and steam turbines in power generation departments.。
II. Usage
Steam BoilerSteam related to thermal equipmentEmissionThe noise emitted can reach up to 130 decibels, far exceeding the noise regulations issued by our country.Industrial Noise Hygiene StandardsSpecified values (e.g., superheated steam at 1 kg/cm² pressure, when discharged into the atmosphere through an opening, can reach a speed of 570-600 meters/second. For saturated steam, the speed can also reach 470-480 meters/second. Such high-speed steam, when discharged into the atmosphere, generates a significant amount of noise due to exceeding the speed of sound, which is 340 meters/second). The noise reduction effect meets the requirements of the "Noise Hygiene Standards for Industrial Enterprises."
ThreeFeatures
Pipe silencers (mufflers) are primarily used for effectively reducing the noise of steam emissions from thermal equipment such as boilers and steam turbines in power generation departments. They are also widely employed in the steam emissions and noise reduction of gases in industries such as oil, chemicals, metallurgy, and textiles..Muffler is a device that prevents sound from propagating while allowing airflow to pass through.Excl.Significant measures for reducing steam exhaust dynamic noiseTo assess the quality of an exhaust muffler, consider the following three main aspects:
The noise reduction capacity of the pipeline muffler meets the requirements of the "Hygienic Standards for Noise in Industrial Enterprises."
2. The adaptability of pipeline silencers (i.e., to low-mid frequency bandwidth and high-temperature, high-pressure conditions).
3. Structural performance of pipeline silencers (Reasonable dimensions, low cost, long lifespan, etc.).
Boiler steam in the power generation department is not only high temperature and high pressure but also has a wide emission frequency band. Simply relying on small-hole soundproofing is insufficient. The Aulon exhaust sound suppressor 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 boilers and pressure vessel pipeline exhaust venting at 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.
FourPrinciple
Boiler exhaust mufflers are manufactured based on the micro-perforated plate noise reduction principle. Steam emissions from power plant boilers typically have high flow rates, and high flow rates can affect the noise reduction of small holes.Please provide the Chinese content that needs to be translated into American English.Therefore, we need to control the flow first, and then the steam that has undergone flow control enters the expansion chamber, where it is further reduced in pressure and noise. 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 each frequency band has been reduced, and the frequency of the sound pressure level has been pushed higher toAbove 20000Hz range, the noise is significantly reduced. However, secondary noise at certain frequencies still requires further attenuation. We have added a resistive acoustic cotton structure to the exterior expansion, which is designed based on the spectral characteristics of the remaining noise emitted by the voltage reducer, to effectively absorb the residual noise. After installation according to specifications, the total noise reduction should reach 30-60 decibels, meeting the requirements.
FiveSelection
The mufflers are meticulously designed according to the user's emission targets and requirements. Consequently, only products that match the emission targets and parameters are eligible.Please provide the Chinese content you would like translated into American English.Excellent sound absorption effect.
Therefore, when ordering a muffler, the following information is required:
(1) Steam emission volume (T/h), as well as pressure and temperature.
（2) Applicable to (such as for boiler steam output or)SafetyValve exhausts, etc.
(3) Exhaust pipe outer diameter, wall thickness.
