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. Application

For use with: Steam BoilersSteam related to thermal equipmentEmissionThe noise emitted can reach up to 130 decibels.

III.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 steam emissions and other gas exhaust silencing in industries such as oil, chemical, metallurgy, and textiles..A muffler is a device that blocks sound transmission while allowing air flow.Significant measures for reducing steam exhaust dynamic noiseTo assess the quality of an exhaust muffler, the following three aspects are primarily considered:

The noise reduction capacity of the pipeline muffler meets the requirements of the "Noise Hygiene Standards for Industrial Enterprises."

2. Pipe mufflers are adaptable to a broad spectrum of low to medium frequencies and high temperatures and pressures.

3. Pipe silencers feature reasonable structural dimensions, low cost, and long lifespan.

The boiler steam in the power generation department is not only high temperature and high pressure but also has a wide emission frequency range. Simply using small hole soundproofing is insufficient. The Zhuli exhaust steam silencer is developed based on the composite noise reduction principle of resistance, jetting, and obstruction, featuring large noise reduction capacity, a broad frequency range, 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 advantage of easy manufacture and installation using stainless steel (1Cr18Ni9Ti, 12Cr1MoV) for the silencer tube.

Four,Principle

Boiler exhaust silencers are manufactured based on the micro-perforated plate noise reduction principle. The steam emissions from power plant boilers typically have high flow rates, and high flow rates have a significant impact on the noise reduction of small holes. Therefore, we need to control the flow first, and then the steam that has been controlled enters the expansion chamber for further pressure reduction and noise reduction. After the steam is subjected to a large volume of pressure reduction, 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 frequency band is reduced, and the sound pressure level frequency is pushed up to above 20,000Hz, significantly 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 based on 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 required standards.

FiveSelection

The mufflers are carefully designed according to the user's emission targets and requirements. Therefore, only products that match the emission targets and parameters are eligible.SureExcellent sound-dampening effect.
