The noise control of air compressor mainly includes muffler, anechoic tunnel and sound insulation technology
The main noise source is the intake and exhaust ports, so the appropriate intake and exhaust muffler should be selected. The frequency spectrum of air compressor intake noise is low-frequency, so the intake muffler should choose resistance structure or impedance composite structure with resistance as main component. The exhaust pressure of the air compressor is large and the air flow speed is high, so the small hole muffler should be used at the air compressor outlet.
Installation of anechoic tunnels
The underground or semi underground tunnel of anechoic tunnel. The wall of the tunnel is made of sound-absorbing bricks. Connect the air inlet pipe of the air compressor with the anechoic tunnel, so that the air enters the air compressor through the anechoic tunnel. The use of anechoic tunnel can greatly reduce the intake noise of air compressor and prolong its service life.
Set up acoustic enclosure
The air flow noise can be reduced to less than 80dB (a) after installing mufflers at the inlet and outlet of the air compressor or setting the noise elimination tunnel. However, the mechanical noise and motor noise of the air compressor are still very high. Therefore, sound insulation cover should be installed on the air compressor unit. 4. Suspended space absorber: in Foshan Lingge air compressor station, the large and open workshop reverberates heavily. If the absorbers are distributed on the roof of the workshop, the noise of the workshop can be reduced by 3-10db (a) and the reverberation time can be reduced by 5-10S
