Compressed Air Silencer

Silencer for compressed air, exhaust muffler for compressed gas, F-type exhaust muffler. Our XYQ series silencers can meet the noise reduction requirements for steam exhaust from various sizes of boilers, safety valve exhaust, and the intake of boiler fans. They are also widely used in the steam exhaust and noise reduction discharge of boilers in the petrochemical, chemical, metallurgical, textile, and other industries, helping to meet the noise standards of industrial enterprises. Features include:

1. Multi-stage silencing design ensures significant noise reduction, with exhaust silencers reaching 35~40 decibels and vent silencers up to 25~30 decibels.

2. Compact, lightweight, easy to install, and maintain.

3. XYQ series, with cylinders made of high-quality stainless steel or carbon steel, offering sufficient strength and corrosion resistance.

4. Capable of independently fixing and absorbing the vertical and horizontal thermal displacement of the exhaust steam piping, ensuring that the piping is not subjected to additional loads due to the installation of silencers, thereby guaranteeing the safety of the exhaust steam piping under thermal operation.

One: Applications and Product Features of Compressed Air Silencers

The safety valve air exhaust silencer is mainly used for effectively reducing the noise of high-temperature and high-pressure steam exhaust from safety valves, PCV valves, and exhaust valves in the power, chemical, and metallurgy industries.

For boiler safety valves and exhaust valves, it can be regarded as a component of the pipeline. After acoustic processing internally, it can reduce the generation and transmission of noise, achieving a noise reduction of 20∽30 decibels (A-weighted level) at the outlet, correspondingly reducing the loudness by more than 60%, resulting in a significant subjective effect. When designing the exhaust silencer for safety valves, the following three aspects should be considered:

1. After silencing, excessive noise should be avoided, with the silencing amount meeting the requirements of the "Noise Hygiene Standards for Industrial Enterprises."

2. Mufflers should be rust-proof, clog-resistant, and capable of withstanding high temperatures, pressures, and air flow.

3. The exhaust volume and blockage ratio of the silencer should be suitable for the smooth exhaust of the safety valve steam flow.

Section 2: Principle of Compressed Air Silencer

The compressed air silencer utilizes the noise reduction principle of through-hole spray and impedance, replacing the micro-porous plate type with large-hole expansion and flow control. It ensures the smooth exhaust of the safety valve steam by design, incorporating multi-level perforated sound absorption and combining it with the impedance noise reduction principle. This allows steam sound waves to enter the countless small holes of the porous sound-absorbing material, exciting the molecular vibration of the porous material, converting the sound energy into heat to overcome frictional resistance and viscosity, thus achieving the ideal noise reduction effect while ensuring the smooth exhaust of steam.

Section 3: Ordering and Selection of Compressed Air Silencers

When ordering mufflers, the following information is required:

(1) Safety valve exhaust flow rate (T/h), set pressure, temperature.

(2) Exhaust pipe outer diameter, wall thickness;

(3) Structure options include small-hole or anti-spray resistance composite. Generally, users choose the composite silencer for better noise reduction, with internal material of stainless steel and shell material of carbon steel; the connection pipe can be selected for welding or flange connection; the support leg can be chosen in leg or ear structure.

Section 4: Specifications and Models

Compressed Air Silencer (Composite Type, suitable for temperatures up to 300 degrees, pressure up to 6.4 Mpa)

TB Type Exhaust Muffler, where TB stands for Absorptive Muffler with Sound Attenuation Enclosure (Composite), filled with sound absorption material. Gases enter from the bottom pipe and exit from the top. Suitable for pressures up to 6.4Mpa due to the sound absorption material; otherwise, the material may be blown out. The shell is made of carbon steel, suitable for temperatures up to 300 degrees.
