1)Muffler
To control the noise of cooling tower exhaust fan inlet and outlet, special muffler can be installed at the cooling tower inlet and exhaust. For the cooling tower with outstanding noise at the air inlet and outlet, this method has obvious noise reduction effect;
2)Sound barrier
When sound waves encounter obstacles in the process of propagation, three phenomena of reflection, transmittance and bypassing will occur. Sound barrier is in the sound source and the sound point between the insertion of a facility to isolate and absorb the sound source to reach the sound point of the direct sound waves, so that part of the sound wave is blocked by the reflection, part of the sound wave is absorbed by the attenuation through the screen body transmittance (very small) and the top of the screen around the additional form of attenuation to reach the sound point, to achieve to alleviate the impact of the sound point of the noise, to achieve the purpose of the noise effect of the noise reduction.
3)Falling water energy dissipation noise reduction device
In the cooling tower before the falling water directly hit the water surface, so that the falling water first in the slanting surface through the noiseless rubbing, viscous deceleration, picking flow separation, evacuation of sprinkler and other forms of dissipation of the transition, to achieve the elimination of the impact of the noise of the noise of the falling water management effect, is the source for the source of the tower is a management technology.
4) vibration damper and rubber soft connection
Cooling tower feet and the ground between the installation of damping spring vibration damper, rubber soft joints installed in the pipeline, can effectively isolate the vibration transmission to prevent noise radiation.
Cooling tower noise management technology and cooling tower sound insulation noise reduction program, Nanchang Jia Green specializes in cooling tower noise management and cooling tower sound insulation noise reduction.
