南京扬子石化公司化工厂两座大型空压机站及配套设施功率高、体积大、噪声严重、影响面广。根据该机噪声的峰值频率集中在高频区域的特点，我们充分利用现场地形地物，采取科学合理的隔、吸、反射、消声等措施，用有限的资金，在短期内取得了较满意的降噪效果，并达到了国家有关的工业卫生标准。 Nanjing Yangzi Petrochemical Company chemical plant two large air compressor stations and ancillary facilities high power, large size, serious noise, wide impact. According to the characteristic that the peak frequency of the machine noise is concentrated in the high-frequency area, we make full use of on-site topography to take scientific and reasonable measures such as separation, suction, reflection and noise elimination and achieved satisfactory results in a short period of time with limited funds Noise reduction effect, and reached the relevant state industrial hygiene standards.
