DESCRIPTION

Muffler is designed and manufactured for noise reduction of boilers, steam turbines, deaerators, fans and other equipment used in power plants.

To measure the quality of mufflers, the following three aspects are considered.

1. Muffler's muffling performance; (noise attenuation and spectrum characteristics)

2. Aerodynamic performance of mufflers; (pressure loss, etc.)

3. The structure and performance of the muffler. (size, price, lifespan, etc.)

Noise attenuation characteristics of mufflers. The resistance to jet impedance muffler is superior to each frequency noise.

The suitable wind speed of the muffler is generally 6-8m/s, which should not exceed 12m/s when the muffler is high, and the pressure loss of the muffler should be paid attention to.

Attention should be paid to the cross-sectional area of the net passage of the muffler. When the air duct is connected with the muffler, amplification should be done.

The installation of mufflers and other muffling equipment shall have a separate load-bearing suspender or base, and shall be connected with the sound source equipment through a soft joint.

When two silencing elbows are connected in series, the connection spacing between the two elbows should be 2.5 times longer than the diagonal length of the elbow section.

For high temperature, high humidity, oil mist, water vapor environmental systems generally choose microporous structure silencing equipment, for clean requirements such as operating rooms, recording rooms, clean rooms and other environmental systems, microporous structure silencing equipment should be used.

When the adjacent building pipes are in collusion, attention should be paid to the interaction of indoor noise through the pipes, and the air outlet should be silenced.

Muffler selection should be based on fire prevention, moisture proof, corrosion protection, cleanliness requirements, installation space location, noise source spectrum characteristics, system natural sound attenuation, system airflow noise, room allowable noise level, allowable pressure loss, equipment prices and many other factors are considered comprehensively and based on the actual situation. Generally speaking, the greater the muffler's silencing capacity, the greater the pressure loss and price; the smaller the pressure loss, the greater the space the muffler occupies when the muffler's silencing capacity is the same.
