ForBaffled exhaust silencerA component of the pipeline, which, after internal acoustic processing, can reduce the generation and transmission of noise, steam blowing tube usedSilencerThe design cannot solely focus on noise reduction effects; it must first meet the requirements of steam blow pipes, ensuring high flow rates, low resistance, and high momentum. Subsequently, noise reduction can be achieved through techniques such as pressure reduction, throttling, expansion, and frequency shifting.
To meet the high steam temperature requirement during supercritical unit steam blowing, the materials selected for the inlet of the blowing pipe silencer and throttle tube are 0Cr18Ni9, while the materials for the second-stage throttle tube and housing are 20g or 16MnR.
2. Designed for harsh working conditions, the medium can contain water, iron debris (particle size up to ∮30mm), and engineering materials.
3. Noise reduction up to 20dB~40dB(A). Suitable for (blowing methods): Constant Pressure Blower, Pressure Reduction Blower, Oxygen Enrichment Blower.
4. Refer to the technical specifications of GB150-1998 "Steel Pressure Vessels" during design and manufacturing. To ensure the use of silencers, structural measures and requirements must be established to meet strength, thermal expansion, displacement, drainage, corrosion allowance, and protection against damage from solid debris. The quality of silencer manufacturing should be supervised and inspected by professionals from the design and supervisory authorities.
Boiler blowdown is a quick and easy method to remove debris and obstructions from pipes: the process generates a tremendous noise of about 130-150 dB.Blowpipe MufflerThe technology can significantly reduce the generation and transmission of noise, achieving an acoustic noise reduction of over 30-40 decibels (A-weighted) for the exhaust noise, correspondingly lowering the loudness by more than 60 decibels, resulting in a noticeable effect on the subjective perception.
