Introduction to chimney muffler:


铂莱娱乐场Chimney noise disturbing the public, how to - chimney muffler, using chimney muffler - chimney noise management. Chimney noise, such as in chemical plants and cement plants, has high chimneys and high air vents. The noise from the air vents presents a low-frequency buzzing sound, which affects a considerable area of the surrounding environment and brings inconvenience to residents' lives. The chimney muffler applies the principles of acoustics and aerodynamics, and adopts a noise reduction measure of installing impedance composite silencers inside the chimney, while reducing high, -, and low-frequency noise. It also increases the noise reduction effect on low-frequency noise, making the surrounding factory and sensitive areas of the chimney achieve good noise reduction results. At the same time, it improves the aerodynamic structure of the muffler, reduces smoke exhaust resistance loss, and ensures chimney smoke emissions; The muffler structure and installation position can be determined based on the chimney noise spectrum, which can meet the noise reduction requirements while reducing costs.


铂莱娱乐场Scope of application of chimney muffler:


The high-temperature airflow generated by boiler combustion in boiler rooms, heating stations, and pipelines collides with chimneys, causing low-frequency noise and resonance of chimneys. Silencers are installed to change the airflow structure, eliminate noise and resonance, and achieve noise reduction


Chimney noise - treatment method:


It is to install a chimney exhaust muffler at the chimney air outlet. Chimney silencers generally use impedance composite silencers, also known as pipeline silencers. If rainproof is required, rainproof silencers should be used.


The chimney silencer has the following features:


1. Good noise reduction ability for low noise;


2. The power of the muffler should be good, that is, the wind resistance should be small;


3. The duration of the muffler should be long.


Chimney silencer -:


铂莱娱乐场-Specially designed to effectively reduce low-frequency noise through sound reduction; In terms of materials, using weather resistant materials is a good choice for manufacturers who are troubled by chimney noise, especially for high temperature and sulfur-containing flue gas.


铂莱娱乐场Noise reduction - energy: the noise reduction is 15-35dB; The frequency band is 31.5-8000Hz.


铂莱娱乐场Resistance loss: The resistance corresponding to the noise reduction is 15-120Pa.


Usage: Suitable for chimney discharge conditions, with temperatures ranging from - to 450 ℃, corrosive, and gas containing certain dust and impurities, with a flow rate of 2-15m/s.


铂莱娱乐场Noise Reduction - Result:


Ensure that the chimney can meet the relevant standards of the Industrial Enterprise Boundary Noise Emission Standard (GB12348-2008) after treatment.


Principle of chimney muffler:


The chimney muffler adopts the principle of through-hole spraying and blocking for noise reduction. It replaces the microporous perforated plate type with a large hole expansion and flow control. On the structure, the principle of ensuring smooth exhaust of the safety door is adopted, and the layered perforated sound absorption is combined with the blocking and silencing principle to allow steam sound waves to enter several small holes in the porous sound-absorbing material. The molecular vibration of the porous material is generated, and the sound energy is converted into heat energy to overcome frictional resistance and viscous force, achieving the desired sound reduction effect, -Ensure the smooth discharge of steam.
