The main silencing facility in the operation management and monitoring project is a closed brick-concrete structure, with the muffler components installed inside and the concealed pipelines concealed. In addition to the building, the whole system is not in contact with the open air environment. There is no maintenance and overhaul work for several years, and no special management is required. Monitoring results: The company's environmental monitoring station and the city environmental monitoring station measured at the exhaust vent for 72 hours, and when the fan was overloaded (greater than 40m, /min), the noise level never exceeded 80dB (A), which is equivalent. The noise floor of the production plant area achieves the design effect.
Benefit Evaluation This design transfers hazardous noise sources and performs step-by-step treatment. It seems to increase engineering investment, such as pipelines and accessories, civil rooms, silencers, etc. It is designed and installed directly at the sound source to achieve such a functional large metal. The sound-absorbing facilities consisting of parts are more valuable in terms of one-time investment comparison and transfer method measures. Because in engineering practice, sound absorption and sound insulation are closely combined. It is difficult to achieve a noise reduction effect of 50 dB (A) or more with an overall muffler manufactured by a metal plate. Because of the sound, the Shandong filter plate will be mutually permeable and diffused through the muffler wall components. On the other hand, the sound source is located above the top of the highway sidewalk, and the large-scale sound-absorbing facilities are designed and installed. In addition to the hidden noise and public hazard, there is still an environment. Beautiful and high-altitude maintenance difficulties, short service life and many other disadvantages, from the economic and practical, safe and reliable, environmental benefits and other comprehensive comments, this comprehensive design and practice is optimized and reasonable.
To correct the noise of wind turbine blower noise, to report the noise law generated by instantaneous continuous injection of airflow, to reveal the noise change step by step and to explain the noise reduction process step by step, put forward the method of highlighting the key design and management, and combined with the actual cure, achieved governance The ideal effect of noise.
