Micro-hole silencers are mainly used for effectively reducing noise from high-temperature and high-pressure steam emissions in industries such as electricity, chemical, and metallurgy.
Steam mufflers and steam silencers primarily target medium to high-frequency noise. Therefore, our TA series steam mufflers/silencers utilize a through-hole expansion and pressure reduction principle combined with sound absorption and noise reduction. This includes replacing small-hole injection with through-hole expansion and pressure reduction, ensuring smooth steam exhaust in the structure. The composite sound absorption and noise reduction cover and panels effectively absorb any remaining medium to high-frequency noise. The PA series steam mufflers/silencers are constructed with through-hole expansion and pressure reduction tubes and small-hole jet exhaust shells. The expansion and pressure reduction tubes distribute the steam flow, thereby reducing noise and preventing the recurrence of sound. The small-hole jet exhaust shells are small components with many holes, machined from stainless steel, which redirect the wideband exhaust noise to frequencies less sensitive to the human ear and accelerate the attenuation of sound.
Product Features:
1、Miniature mufflerThe noise reduction meets the requirements of the "Industrial Enterprise Noise Hygiene Standard," reducing the export noise by 36-39 decibels (A-weighted).
2、Miniature mufflerSilencing without affecting valve flow, and without impacting the valve's lift and return.
3、Miniature mufflerThe structure's performance accommodates the impact of sudden, high-temperature, high-pressure steam emissions.
Operating Principle:
Miniature mufflerIt is designed based on a reasonable sound absorption principle. High-pressure steam, after passing through a single controlled flow in the silencer, enters the pressure-reducing chamber. After being expanded and depressurized in a large volume, it forms low-pressure steam and is emitted. During this process, part of the steam's internal energy is converted into sound energy of a certain frequency, although the noise power is greatly reduced, it often remains above the standard value due to reasons such as exhaust steam deviating from the design value. To address this, a composite multi-material sound absorption and insulation hood is designed outside the pressure-reducing chamber. The composite hood is designed according to the spectral characteristics of the residual noise emitted by the pressure-reducing chamber and is used to effectively absorb the remaining noise. After installation as required by the user, the total sound absorption can reach 36-42 decibels. Currently, to suppress the noise of high-pressure gas flow exhaust, various types of silencers have been developed, with most of their principles using multi-stage throttling and pressure reduction. However, due to their complex structures, heavy weights, and difficulty in maintenance, their application scope is limited. This steam silencer, like the steam silencer, overcomes the above shortcomings and is designed based on a reasonable sound absorption principle. After passing through a single controlled flow in the silencer, high-pressure steam enters the pressure-reducing chamber, where it is expanded in a large volume to form low-pressure steam and is emitted. During this process, part of the steam's internal energy is converted into sound energy of a certain frequency, greatly reducing the noise. Within a single, mixed-flow silencer shell, 2-4 energy-absorbing and noise-suppressing inner shells are arranged. These inner shells can move vertically and horizontally to absorb the thermal expansion of the exhaust gas管道. A double-layered sound insulation shield is designed outside the pressure-reducing chamber.
Steam mufflers are designed based on a reasonable noise reduction principle. High-pressure steam, after passing through a single control flow in the muffler, enters a pressure-reducing chamber. It is then expanded and pressure-reduced in a large volume, forming low-pressure steam that is emitted. During this process, some of the steam's internal energy is converted into sound energy of a certain frequency, which, although significantly reduced in power, often remains above the standard noise level due to reasons such as the steam discharge deviating from the design value. To address this, a composite noise-reducing and absorbing hood with a multi-material structure is designed outside the pressure-reducing chamber. This composite hood is tailored to the spectral characteristics of the residual noise emitted by the pressure-reducing chamber, effectively absorbing the remaining noise. After installation according to specifications, the total noise reduction can reach 36-42 decibels. To suppress the noise from high-pressure gas flow emissions, various types of mufflers are available, with most using a multi-stage throttling and pressure-reduction principle. However, their complex structure, heavy weight, and difficulty in maintenance limit their application. Our steam muffler and steam muffler overcome these shortcomings, integrating a reasonable noise reduction principle. High-pressure steam, after passing through a single control flow in the muffler, enters a pressure-reducing chamber where it is expanded and pressure-reduced in a large volume, forming low-pressure steam that is emitted. During this process, some of the steam's internal energy is converted into sound energy of a certain frequency, significantly reducing the noise. Inside a single, mixed-flow muffler shell, 2-4 energy-reducing and noise-suppressing inner shells are arranged. These inner shells can move vertically and horizontally to absorb the thermal expansion of the exhaust pipe. Outside the pressure-reducing chamber, a double-layered noise-reducing hood is designed.
