Induced draft fan silencer

The induced draft fan silencer is mainly suitable for reducing the intake noise of Roots series fans, and can also be used for noise reduction of exhaust pipes and other high-pressure fans. The induced draft fan has a noise reduction capacity of 15-30dB (A) and a pressure loss of less than 500Pa.

Overview of induced draft fan muffler

Specification and model of induced draft fan muffler

YF muffler is suitable for various types of fan fans and has cotton filling.

The induced draft fan muffler, in the same form as the exhaust pipe muffler and the drum induced draft fan muffler, adopts the principle of resistance absorption noise reduction that has a significant effect on high-frequency broadband, as well as the principle of resistance noise reduction that has good effects on low frequency and pulsation, as well as micro perforated silencers and impedance composite silencers.

Barrier muffler is a type of absorption muffler produced, which is generally divided into straight pipe, sheet, folded plate, honeycomb, acoustic flow, labyrinth, and elbow types according to the different airflow channel structures. A silencer is a device that utilizes sound waves transmitted through a porous sound-absorbing material to undergo friction and viscous resistance, converting sound energy into thermal energy for dissipation, thereby achieving the goal of noise reduction. It is a type of muffler that applies to all silencers.

The principle of anti muffler is different from that of anti muffler in terms of noise reduction. It cannot directly absorb sound energy, but instead uses the interface or adjacent resonant cavity on the pipeline to reflect and interfere with certain frequency sound waves transmitted along the pipeline at the interface, thereby achieving the purpose of noise reduction. It is divided into expansion chamber type mufflers and resonance type mufflers.

In the field of international noise control engineering, noise is dominated by broadband, and the combination of resistance absorption noise reduction and anti noise reduction is used to control high-intensity broadband noise.

Selection of induced draft fan muffler:

1: Flow rate, pressure.

2: Interface size.

3: Is it installed at - or at the outlet, and is it equipped with a rain cap.

Note:

1. Due to the complex exhaust objects of user thermal equipment, we can design various specifications of mufflers based on exhaust volume, steam pressure, temperature, and pipe size.

2. Fan type silencers generally require joint disinfection, that is, the installation of silencers and compartments, and the fan base must be equipped with shock-absorbing pads.
