1. Identification and evaluation of noise sources: First, identify the main noise sources and understand their frequency, intensity and distribution. This helps to make a targeted governance plan.
2. Sound insulation measures: use sound insulation materials to reduce noise transmission. Sound insulation wall, sound insulation cover, etc. It can be built near the noise source to block the propagation path of noise.
3. Vibration reduction measures: Use vibration reduction devices to reduce the noise generated by mechanical vibration. This includes the installation of shock-absorbing pads, shock-absorbing hangers, etc. On the fan and supporting structure.
4. Fan design optimization: consider the factors of reducing noise in the design stage of the fan. For example, optimize the blade shape, reduce air turbulence and so on.
5. Operation management: Reasonable operation management can reduce noise. For example, adjust the speed and running time of the fan to reduce noise.
6. Maintenance: Check and maintain the fan equipment regularly to ensure that it is in the best condition and reduce the generation of abnormal noise.
7. Noise monitoring and control: The noise monitoring system is used to monitor the noise level in real time, and once it exceeds the specified standard, control measures will be taken.
8. Technical upgrade: Advanced noise control technology, such as active noise control technology, is adopted to reduce the noise level by emitting sound waves to cancel the noise.
9. Community participation: If fan noise affects the surrounding communities, you can communicate with local residents and work out solutions.
10. Comply with laws and regulations: comply with local and national noise emission laws and regulations to ensure that the noise level of the fan is within the allowable range.
The comprehensive application of the above methods can effectively control the noise problem of industrial fans and reduce its impact on the environment and human health.
