Safety Valve Muffler

Product Details

I. Definition

Pipe silencers (mufflers) are primarily used for effectively silencing steam emissions from thermal equipment such as boilers and steam turbines in power generation departments.。

II. Application

Steam BoilerSteam related to thermal equipmentEmissionThe noise emitted can reach up to 130 decibels, far exceeding the noise regulations stipulated by our country.Industrial Enterprise Noise Hygiene StandardsSpecified values (e.g., superheated steam at 1 kg/cm² pressure, when discharged into the atmosphere through an opening, can reach a velocity of 570-600 meters/second. For saturated steam, the velocity can also reach 470-480 meters/second. At such high velocities, when discharged into the atmosphere, the steam exceeds the speed of sound (340 meters/second), resulting in significant noise). The noise reduction effect meets the requirements of the "Noise Hygiene Standards for Industrial Enterprises."

III.Features

Pipe mufflers (noise suppressors) 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 the steam emissions and noise suppression of other gases in industries such as oil, chemical, metallurgy, and textile..A muffler is a device that blocks sound transmission while allowing air flow to pass through.Excl.Significant measures for reducing the dynamic noise of steam exhaust. Assessing the quality of steam exhaust mufflers primarily involves considering the following three aspects:

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

2. The adaptability of pipeline silencers (i.e., suitable for low to mid-frequency bandwidth and high temperature and 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 frequency range of emissions. Simply using small-hole sound absorption is insufficient. The Zuli Exhaust Steam Silencer is developed based on the composite noise reduction principle of resistance, injection, and obstruction, featuring large noise reduction capacity, wide frequency adaptability, and targeted design (for various boiler and pressure vessel pipeline exhaust venting, including parameters such as low, medium, sub-high, high, ultra-high, subcritical, and supercritical pressures), with the advantages of easy manufacturing and installation using stainless steel (1Cr18Ni9Ti, 12Cr1MoV) for the silencer.

FourPrinciple

Boiler exhaust silencers 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 you would like translated into American English.Therefore, we first need to control the flow. After passing through the flow control, the steam enters the expansion chamber, where it is further reduced in pressure and sound dampened. After the steam is subjected to a large-volume pressure reduction, it forms low-pressure steam that is ejected. During this process, the airflow is ejected through small-diameter orifices. After ejection, the sound power in each harmonic band is reduced, and the frequency of the sound pressure level is elevated toAbove 20,000Hz, the noise is significantly reduced. However, secondary noise at certain frequencies still requires further attenuation. We have added a resistive sound-absorbing cotton structure to the exterior expansion, which is designed based on the frequency spectrum characteristics of the residual noise emitted by the pressure-reducing unit to effectively absorb the remaining noise. After the user installs it according to specifications, the total noise reduction should reach 30-60 decibels to meet the requirements.

FiveSelection
