摘要
通过对乳粉车间浓缩设备降膜蒸发器发射噪声测试,验证了气流喷射噪声是最主要噪声,运用现代测试和分析手段,结合马大猷教授的喷射气流噪声理论,提出主动降噪的理论依据和有效措施。
It is concluded that the air-flow noise is the most noise by testing on falling-film Evaporator of concentrator in milk powder workplace. Together with professor Madaqil＇ s Jetting Air Flow theory and applying the modern testing and analyzing methods, the author proposes the theoretical is and efficient measures on preventing noise.
