Section 1: Exhaust Muffler Application:

This series of silencers is primarily used for effective noise reduction in equipment such as power plants, chemical industry, metallurgy, mining, textile industry boilers, safety valves, gas emissions, fan exhausts, vacuum pump exhausts, compressed air exhausts, diesel engine exhausts, and generator set exhausts.

Section II: Features of Exhaust Muffler:

1. Exhaust muffler

To suppress the noise from high-pressure gas flow emissions, this type of silencer is designed based on a comprehensive and reasonable noise reduction principle. After passing through a single flow control within the silencer, the gas enters the pressure-reducing chamber, where it is expanded in a large volume, thereby forming a low-pressure gas flow that is then ejected. During this process, a portion of the steam's internal energy is converted into sound energy of a certain frequency. Although the noise power is significantly reduced, it often remains above the standard value due to various reasons such as the exhaust steam deviating from the design value. To address this, a double-layered sound-insulating enclosure is designed around the pressure-reducing chamber, tailored to the spectral characteristics of the residual noise emitted by the chamber, for effective absorption of the remaining noise. After installation according to specifications, the total noise reduction can reach 35 to 60 decibels.

2. Exhaust muffler

For safety doors on gas emission devices, the exhaust should not only minimize noise but also ensure smooth airflow. Therefore, the conventional methods of multi-stage throttling and small-hole injection for noise reduction are not suitable. This has always been a design challenge for safety door silencers and a reason for their poor noise reduction performance. The silencer of this safety door also employs the noise reduction principle of resistance, injection, and obstruction, replacing the smaller diameter flow control holes with larger diameter holes for expansion, thereby enhancing the resistance, injection, and obstruction noise reduction effects structurally. This achieves an ideal noise reduction effect.

3. Low-pressure Exhaust Muffler (Type TD)

A large number of industrial and mining enterprises utilize low-pressure boilers of 0.13MPa and below, and there are also numerous low-pressure thermal devices in power plant thermal systems, such as back-pressure turbines, deaerators, auxiliary exhaust pumps, turbine oil pumps, continuous blowdown from boilers, periodic blowdown, and more. These equipment's exhaust pipes require the installation of noise mufflers that are structurally lightweight and easier to install. Our company designs corresponding mufflers for different noise reduction targets, meeting the needs of our customers.
