One: Application of Exhaust Muffler:

This series of silencers is primarily used for effective noise reduction in equipment such as power plants, chemical, metallurgical, mining, textile industry boilers, safety valve exhausts, 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 the gas is once controlled within the silencer, it enters the pressure-reducing chamber where it is expanded through a large volume, thereby forming a low-pressure gas flow that is ejected. During this process, a portion of the gas flow's internal energy is converted into sound energy of certain frequencies. Although the noise power is greatly reduced, it often remains above the standard value due to various reasons such as deviations from the design pressure. To address this, a double-layered sound-insulating hood is designed outside the pressure-reducing chamber, tailored to the spectral characteristics of the residual noise emitted by the pressure-reducing chamber, to effectively absorb the remaining noise. After installation according to the user's requirements, the total noise reduction can reach 35~60 decibels.

2. Exhaust muffler

For safety doors on equipment like gas emission systems, the exhaust should not only minimize noise but also allow for smooth airflow. Therefore, the traditional 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. This safety door's silencer also employs the noise reduction principle of resistance, injection, and obstruction, replacing the smaller diameter flow control holes with larger holes for expansion, thereby enhancing the resistance, injection, and obstruction noise reduction effects structurally, achieving an ideal noise reduction result.

3. Low-pressure exhaust muffler (Type TD)

Many industrial and mining enterprises use a large number of low-pressure boilers with a pressure of 0.13 MPa or less. In power plant thermal systems, there are also numerous low-pressure thermal units, such as back-pressure turbines, deaerators, auxiliary exhaust blowers, turbine oil pumps, continuous blowdown from boilers, periodic blowdown, and more. The exhaust pipes of these equipment require the installation of mufflers that are lightweight in structure and easier to install. Our company designs corresponding mufflers for different noise-reduction targets, capable of meeting customer requirements.

Section 3: Order Instructions:

1. Application objects (such as boiler ignition exhaust, safety valve exhaust, fans, deaerator exhaust, etc.).

2. Boiler evaporation capacity, steam pressure, and temperature.

3. Emission Volume: t/h.

4. Interface pipe diameter and wall thickness.

5. As long as the technical specifications provided by the customer are complete, our company can design and produce any type and specification of muffler on behalf of them.

IV. Installation Precautions:

During shipment, detailed instructions for the packing materials are included.

Description:

1. When the user's exhaust manifold specification does not match the table, the outer dimensions will vary.

2. Our factory will design steam exhaust equipment based on the user's specified steam volume, pressure, and pipe size.

V. Product Showcase

If there is sufficient installation space for the cross-section and length of the silencer, you can change the cross-section size when the height is insufficient but the width is sufficient, expanding towards the width. Our company can supply according to design requirements. Increasing the length of the silencer can enhance the noise reduction, but it also results in increased resistance loss.
