Pipe muffler manufacturer

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.。

Part II: Usage

Steam BoilerSteam related to thermal equipmentEmissionThe emitted noise can reach up to 130 decibels, far exceeding the standards set forth in our country's "Industrial noise hygiene standardsRegulated values (e.g., superheated steam at 1 kg/cm² pressure can reach speeds of 570-600 meters/second when expelled into the atmosphere through a hole, while saturated steam can reach 470-480 meters/second. Such high-speed steam, when expelled at speeds exceeding the speed of sound (340 meters/second), generates significant noise). The noise reduction meets the requirements of the "Industrial Enterprise Noise Hygiene Standards."

ThreeFeatures

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 noise reduction of gases in industries such as oil, chemicals, metallurgy, and textiles.A muffler is a device that blocks sound transmission while allowing air flow to pass through.ExcludingSignificant measures for reducing the dynamic noise of steam exhaustTo evaluate the quality of an exhaust muffler, primarily consider the following three aspects:

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

2. The adaptability of pipe silencers (i.e., suitable for low to mid-frequency bandwidth and high temperature and pressure conditions).

3. Structural performance of pipeline silencers (including reasonable dimensions, low cost, and long service life).

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 sound absorption is insufficient. The Assistive Exhaust Sound Absorber is developed based on the composite noise reduction principle of resistance, injection, and damping. It boasts large noise reduction capacity, a wide frequency range of adaptation, and targeted design (for various boiler and pressure vessel pipeline exhaust gas discharge, including parameters such as low, medium, sub-high, high, ultra-high, sub-critical, and super-critical pressures). The noise reduction tube is made of stainless steel (1Cr18Ni9Ti, 12Cr1MoV) for easy manufacturing and installation.

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.So, we first need to control the flow. The steam that has been through once control flow then enters the expansion chamber, where it is further depressurized and noise reduced. After the steam is depressurized in the 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 across various frequency bands has been reduced, while the frequency of the sound pressure level has been elevated toAbove 20,000Hz, the noise is greatly 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 spectrum characteristics of the residual noise emitted by the voltage reducer, to effectively absorb the remaining noise. After the user installs it as required, the total noise reduction should reach 30-60 decibels to meet the specifications.

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 to be translated.Excellent sound-dampening effect.
