Compressed air exhaust muffler
Silencers can meet the noise reduction and noise reduction requirements of various sizes of boilers for air exhaust, safety valve exhaust, and boiler fan inlet. They are also widely used for boiler steam emissions and other gas noise reduction emissions in industries such as petroleum, chemical, metallurgical, and textile, to meet the noise standards of industrial enterprises. Their characteristics are as follows:
1. Adopting multi-stage noise reduction, with a large amount of noise reduction, the exhaust muffler can reach 35-40 decibels; The venting muffler can reach 25-30 decibels.
2. Small size, light weight, easy installation, and easy maintenance.
3. The XYQ series uses stainless steel or carbon steel for the cylinder body, which has sufficient strength and corrosion resistance.
4. It can independently fix and absorb the vertical and horizontal thermal displacement of the exhaust pipe, so that the exhaust pipe is not subjected to additional loads due to the installation of the muffler, ensuring the safety of the exhaust pipe under thermal energy operation.

One: Application and product characteristics of compressed air muffler
The safety door compressed air muffler is mainly used for effective noise reduction of high-temperature and high-pressure steam emissions from safety valves, PCV valves, and exhaust valves in industries such as power, chemical, and metallurgy.
For boiler safety valves and exhaust valves, they can be seen as an integral part of the pipeline. After acoustic treatment inside, they can reduce the generation and propagation of noise, making the outlet noise reduction reach 20-30 decibels (A-level), and correspondingly reducing the loudness by more than 60%. The subjective feeling has a significant effect. Design safety valve
The pressure exhaust muffler should consider the following three aspects:
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. Mufflers should be rust proof, anti blocking, resistant to high temperatures, high pressures, and high airflow.
3. The emission and blockage ratio of the muffler should be adapted to the smooth elimination of the exhaust airflow of the safety valve.
2、 Principle of Compressed Air Muffler
The compressed air muffler adopts the principle of through hole spraying and resistance for noise reduction, in which large holes are used to expand and control the flow instead of micro hole plate type. In terms of structure, the principle of smooth exhaust of the safety door is first established, and multi-level perforated sound absorption is combined with the principle of resistance noise reduction, allowing steam sound waves to enter countless small holes in the porous sound-absorbing material, exciting the molecular vibration of the porous material, and turning the sound energy into heat energy to overcome frictional resistance and viscous force, thus achieving the ideal noise reduction effect and smoothly eliminating the airflow.
3、 Selection and ordering of compressed air mufflers
When ordering a muffler, the following information must be provided:
(1) What is the exhaust volume (T/h), start-up pressure, and temperature of the safety valve.
(2) Outer diameter and wall thickness of exhaust pipe;
(3) The structure can be selected as small hole type or anti spray composite type. General users choose composite mufflers with good noise reduction effect, made of stainless steel inside and carbon steel shell material; Welding or flange docking can be selected for takeover; Legs can be designed with leg or ear structures;
4、 Specification and model
Compressed air muffler (composite type, suitable for temperatures up to 300 degrees and pressures up to 6.4Mpa)
TB type exhaust muffler, TB refers to a composite muffler with a sound blocking cover, filled with silencing cotton. Gas enters from the bottom and is discharged from the top. Due to the presence of sound-absorbing cotton filling, it is suitable for pressures up to 6.4 Mpa, otherwise the filling will be blown out, and the shell made of carbon steel is suitable for pressures up to 300 degrees.
TB-1.6-10000/57 model meaning: TB represents a composite exhaust muffler, 57 represents an interface outer diameter of 57mm, and 1000 represents an exhaust volume of 1000M3/H.
