One: Oxygen exhaust muffler application:

This series of silencers effectively reduces noise for equipment such as oxygen and gas emissions.

Section II: Features of Oxygen Emission Muffler:

Oxygen Emission Muffler

To suppress the noise from high-pressure gas flow emissions, this type of silencer is designed by integrating reasonable noise reduction principles. After one-time flow control inside the silencer, the gas enters the pressure-reducing chamber, where it is expanded in a large volume, reducing the pressure to form low-pressure gas flow, which is then ejected. During this process, a portion of the internal energy of the gas flow is converted into sound energy of certain frequencies, and although the noise power is greatly reduced, it often remains above the standard value due to various reasons such as the exhaust gas deviating from the design value. To address this, a double-layered soundproofing hood is designed outside the pressure-reducing chamber, tailored to the frequency spectrum characteristics of the residual noise emitted by the pressure-reducing chamber, for effective absorption of the remaining noise. After installation according to specifications, the total noise reduction can reach 36~42 decibels.

2. Oxygen Emission Muffler

For safety doors on equipment like gas emissions, the exhaust should avoid excessive noise while allowing smooth airflow. Therefore, the commonly used methods of multi-stage throttling and small-hole injection for noise reduction are not suitable. This limitation has always been a design challenge for safety door silencers and a reason for their poor noise reduction performance. The noise reducer of this novel 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. This structural enhancement strengthens the resistance, injection, and obstruction noise reduction effects, achieving an ideal noise reduction result.

3. Oxygen Emission Muffler

A significant number of industrial and mining enterprises utilize low-pressure boilers with pressures of 0.13 MPa or less. In power plant thermal systems, there are also numerous low-pressure thermal devices, such as back-pressure turbines, deaerators, auxiliary exhaust blowers, turbine oil pumps, continuous blowdown of boilers, and periodic blowdown, etc. These equipment require exhaust pipes to be equipped with noise suppressors that are lightweight in structure and easier to install. Our company designs dedicated noise suppressors for different suppression targets, capable of meeting customer requirements.
