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 for thermal equipmentEmissionThe noise emitted can reach up to 130 decibels.

III.Features

Pipe mufflers (silencers) are primarily used for effectively muffling steam emissions from thermal equipment such as boilers and steam turbines in power generation departments. They are also widely employed in industries such as oil, chemicals, metallurgy, and textiles for boiler steam emissions and other gas exhaust muffling..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, consider the following three main aspects:

The noise attenuation 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 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 emission frequency range. Simply relying on small hole noise reduction is insufficient. The Zuli Exhaust Noise Attenuator is developed based on the composite noise reduction principle of resistance, injection, and impedance, featuring large noise reduction capacity, wide frequency adaptability, and targeted design (for various boiler and pressure vessel pipeline exhausts, including low-pressure, medium-pressure, sub-high-pressure, high-pressure, ultra-high-pressure, subcritical, and supercritical parameters), and the noise reduction chamber is made of stainless steel (1Cr18Ni9Ti, 12Cr1MoV) for easy installation.

FourPrinciple

Boiler exhaust mufflers are manufactured based on the micro-perforated plate noise reduction principle. The steam排放 from power plant boilers generally has high flow rates, and high flow rates significantly affect the noise reduction of small holes. Therefore, we need to control the flow first, and then the steam after the first flow control 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 diameter holes. After ejection, the sound power in each harmonic frequency band is reduced, and the sound pressure level frequency is pushed up to above 20,000Hz, greatly reducing the noise. However, secondary noise at certain frequencies still requires further noise reduction. We add a resistive acoustic 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 according to specifications, the total noise reduction should reach 30-60 decibels, meeting the requirements.

Five,Selection

The muffler is meticulously designed according to the user's emission targets and requirements. Consequently, only products that match the emission targets and parameters are eligible.GoodExcellent sound-dampening effect.
