NOISE CONTROL OF DEDUSTING SYSTEM OF ROASTER

In this paper, on the basis of noise analysis in the roaster area, it can be found that the main noise sources are from the fan and the exhaust. The causes and characteristics of fan noise and exhaust noise are researched. The noise controlling scheme is introduced. And fan muffler, exhaust muffler and absorber for exhaust pipeline are designed, the influence of environment noise is controlled in effect. After the treatment, noise at boundary of industrial enterprises meets the need of national standard.
