Silencer Noise Control For Boiler And Steam Turbine Use

Silencer Noise Control for Discharge Of Steam And Other Gases At High Pressure And Tempe

Introduction:

Steam muffler and steam muffler are designed with the most reasonable muffler principle. The high-pressure steam enters the pressure reducing body after a primary flow control in the muffler, and then expands and reduces the pressure by a large volume again, forming low-pressure steam and then spraying out. In this process, the internal energy of the steam flow is partially converted into sound energy of a certain frequency. Although the noise power is greatly weakened, the exhaust noise is still higher than the standard value due to many reasons such as the deviation of the exhaust steam from the design value. For this reason, a combined multi-material composite sound-absorbing hood is designed outside the pressure-reducing body. The composite sound-absorbing hood is designed according to the spectral characteristics of the residual noise emitted by the pressure-reducing body to effectively absorb the residual noise. . When the user installs as required, the total noise reduction can reach 36 to 42 decibels. At present, in order to suppress the noise emitted by high-pressure airflow, there are many types of mufflers in the world. Most of their principles use multi-stage throttling and pressure reduction. Due to their complex structure, heavy weight, and difficult maintenance, their application range is limited. This steam muffler and steam muffler overcome the above shortcomings and are designed by combining the most reasonable noise reduction principles. The high-pressure steam passes through a control flow in the muffler and then enters the pressure reducing body after large-volume expansion, forming low steam and then spraying out. In this process, the air flow can be partially converted into sound energy of a certain frequency, and its noise It is greatly weakened. In an ejection and mixed flow sound-absorbing shell, 2-4 energy-dissipating and sound-absorbing inner tanks are arranged in a concentrated manner. The inner tank shells can be moved vertically and horizontally to absorb the thermal expansion of the exhaust steam pipe. A double-layer sound barrier is designed for the anti-hypertensive body. Exhaust steam muffler is mainly aimed at medium and high frequency noise, so TA series steam muffler, steam muffler we adopt the muffling principle of through hole expansion and pressure reduction combined with sound absorption and sound absorption, in which through hole expansion and pressure reduction instead of small hole injection , The structure ensures smooth steam exhaust. The structure of the composite sound-absorbing cover and sound-absorbing sheet can effectively absorb the remaining medium and high-frequency noise; PA series steam mufflers and steam mufflers adopt through-hole expansion and pressure reduction tubes And the small hole spraying and dispersing shell. The expansion pressure-reducing tube divides the steam flow, after which the noise is attenuated and the sound generation is reduced. The small hole ejection shell is a small hole element with many small holes that is drilled in stainless steel, which pushes the exhaust noise with a wide frequency band to the ultra-high frequency area where the human ear is insensitive, and accelerates the attenuation of the sound.
