Application of air compressor silencer:

Air compressor silencer (muffler) is mainly used for noise reduction in equipment such as power, petrochemical, metallurgical, mining, and textile industry boiler steam emissions.

Air compressor silencer -:

1. Air compressor silencer

To suppress high-pressure steam flow emission noise. High pressure steam enters the pressure reducing body through secondary flow control in the eliminator, expands the pressure by a large volume, and forms low-pressure steam, which is then sprayed out. During this process, the internal energy of the steam flow is partially converted into sound energy of a certain frequency. Although its noise power is greatly reduced, it often remains above the standard value due to reasons such as deviation from the design value of the exhaust steam.

For the safety doors of boilers and other devices, the exhaust steam should avoid excessive noise and allow the steam flow to be discharged smoothly. Therefore, the commonly seen sound-absorbing methods such as throttling and small hole injection are not used. This limitation is not only difficult to design safety door dampers, but also the reason for the poor sound-absorbing effect of safety door dampers. The suppressor of this type of safety door also adopts the principle of noise reduction through resistance, spraying, and resistance. It replaces the smaller diameter control hole with a large hole expansion, which strengthens the effect of noise reduction through resistance, spraying, and resistance, achieving a reasonable sound reduction effect

For this purpose, a double-layer sound barrier was designed outside the pressure reducing body, and the air compressor muffler was designed based on the spectrum of residual noise emitted by the pressure reducing body to effectively absorb the residual noise. After the user installs according to the requirements, the total noise reduction can reach 15-20 decibels.

2. Low pressure air compressor silencer

Various industrial and mining enterprises use a large number of boilers with a pressure of 13MPa and below, and there are also many low-pressure thermal devices in the power plant thermal system, such as backpressure steam turbines, auxiliary deaerator, auxiliary air extractor, steam turbine oil pump, boiler continuous discharge, periodic discharge, etc. The exhaust pipes of the above equipment require a lightweight and easy to install fire extinguisher. Design useful suppressors for different noise reduction objects to meet user requirements.

3. Soot blowing pipeline exhaust muffler

After the installation and repair of steam boilers and related thermal equipment pipelines, it is necessary to perform steam flushing and cleaning of debris inside the pipelines. During the blowing process, a large amount of noise will be generated. The TC type suppressor adopts a noise reduction structure, which also suppresses noise through the principles of resistance, spray, and resistance. The internal structure integrates the design of PX and TA types.

The air compressor muffler series is produced as an impedance acoustic flow type. Based on the frequency spectrum data obtained from inter site testing of various types of wind turbines in power plants, determine which frequency range requires a large amount of noise reduction as the main basis for designing sound-absorbing structures and fluid channels. At the same time, narrow rectangular channels with larger material finishes are used to enhance absorption results. The noise of a fan often has more than one spectral value when there is large noise, and the requirements for its noise reduction vary for different spectral bands. For this purpose, this product adopts a resistive structure that suppresses high and low frequency noise, as well as an impedance structure that suppresses low and high frequency noise. At the same time, high-frequency and low-frequency noise reduction zones are used in the resistive channel to maximize the bandwidth of noise reduction and achieve good noise reduction results. After the user installs the product as required, the noise limit will not exceed 55-80 decibels.

Application and Production of Air Compressor Silencers:

Air compressor silencers are mainly used in industries such as electric power, chemical industry, metallurgy, etc. to eliminate high temperature and high pressure steam emissions from safety valves, PCV valves, and exhaust valves.

For boiler safety valves and exhaust valves, they can be seen as components of pipelines. After internal acoustic treatment, the generation and transmission of noise can be reduced, resulting in a noise reduction of 10-20 decibels (A sound) at the outlet, and a corresponding reduction of over 60% in loudness. This is subjectively significant. When designing a safety valve exhaust muffler, the following three aspects should be considered:

1. After noise reduction, excessive noise should be avoided, and the amount of noise reduction should meet the requirements of the Industrial Enterprise Noise Hygiene Standards.

2. Silencers should be rust proof, anti clogging, high temperature, high pressure, and high airflow resistant.

3. The emission and blockage ratio of the muffler should be suitable for the smooth elimination of the safety valve exhaust airflow.

Principle of air compressor silencer:

The air compressor muffler adopts the principle of through-hole spraying and blocking for noise reduction. It replaces the micro hole perforated plate type with a large hole expansion and flow control. On the structure, it ensures smooth exhaust of the safety valve, and combines the principle of blocking and silencing to allow steam sound waves to enter several small holes in the porous sound-absorbing material, causing molecular vibration of the porous material. 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.
