Ventilation and noise reduction system for centralized cooling tower

A ventilation and noise reduction system for centralized cooling towers each having a wind outlet, comprising:

• an integrated sound-absorbing and sound-insulation shed which comprises a concrete foundation and a ceiling structure supported by said concrete foundation for positioning above the cooling towers;
• a wind outlet sound-reduction structure which comprises a detachable sealed sound insulation and sound-absorbing structure arranged for supporting above the wind outlets of the cooling towers for absorbing sound from the wind outlets of the cooling towers, a resistive chip muffler positioned on said detachable sealed sound insulation and sound-absorbing structure for muffling the sound from the wind outlets of the cooling towers, and a rainproof sound-attenuation hood positioned on said resistive chip muffler for attenuating the sound from the wind outlets of the cooling towers and for sheltering rain;
• and
• a wind inlet sound-reduction structure which comprises a pendent two-side sound absorber extended at each eave of said ceiling structure of said integrated sound-absorbing and sound-insulation shed, a waterproof wall arranged for being formed on a ground, and a sound barrier upwardly extended from said waterproof wall to form a wind inlet sound-reduction channel between said pendent two-side sound absorber and said sound barrier.
