摘要
进行了排油烟噪声的频谱分析 ,研制出一种可防油烟雾、降噪性能好 (插入损失达 31 .8～ 33.9d BA )、耐高温、使用寿命长的排油烟通风复合式消声器。该技术经过两年的实际应用证明 ,降噪能力强 ,效果稳定 ,解决了同时降噪和排油烟的难题 。
The noise of exhausting cooking oil smoke from catering trade contains aerodynamic noise,electric and magnetic noise and flame noise.After analyzing frequency characteristics of the noise,we have designed a new type of an excellent impedance compound muffler.The muffler can ensure that not only does the environmental noise meet the standard,but also the pollution of cooking oil smoke can be reduced.
