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 Boilers &Steam related to thermal equipmentEmissionThe emitted noise can reach up to 130 decibels.

Three,Features

Pipe silencers (mufflers) are mainly used for effective noise reduction of steam emissions from thermal equipment such as boilers and steam turbines in power generation departments. They are also widely employed in industries like oil, chemicals, metallurgy, and textiles for noise reduction of boiler steam emissions and other gas discharge emissions.A muffler is a device that prevents the transmission of sound while allowing air flow through.Significant measures for reducing the dynamic noise of steam exhaustTo evaluate the quality of an exhaust muffler, 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 frequency spectrum, including low and medium frequencies, and can withstand 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 impedance, featuring large noise reduction capacity, wide frequency adaptability, and targeted design (for various boiler and pressure vessel pipeline exhaust emissions such as low-pressure, medium-pressure, sub-high-pressure, high-pressure, ultra-high-pressure, subcritical, and supercritical parameters), 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. Power plant boiler steam emissions typically have high velocities, which significantly impact 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 to further reduce pressure and noise. After the steam is depressurized in a large volume, it forms low-pressure steam that is ejected. During this process, the gas flows out through small orifices. After ejection, the sound power in each frequency band is reduced, and the sound pressure level frequency is pushed up to above 20,000 Hz, greatly reducing the noise. However, secondary noise at certain frequencies still requires further noise reduction. We add a resistive absorbent cotton structure outside the expansion chamber, which is designed based on the frequency spectrum characteristics of the remaining noise emitted by the depressurizing body to effectively absorb the residual noise. After the user installs it according to specifications, the total noise reduction should reach 30-60 decibels to meet the requirements.

Five,Selection

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.SureExcellent sound-dampening effect.
