摘要
随着人们对环境质量要求的提高 ,冷却塔落水噪声对环境的影响正受到人们的重视。冷却塔噪声的治理目标是将受噪声干扰处的噪声级控制在噪声国家标准允许范围 5 0～ 5 5dB。具体来说 ,用冷却塔落水消能降噪装置进行塔内声源治理 ;用声波阻隔技术进行塔外传声途径的治理。通过这 2条途径降低冷却塔落水噪声对环境的影响。
With increase of requirements for environment quality attention has been paid to the influence of the water falling noise from the cooling tower on the environment. The target of noise control from the cooling tower is to control the noise level at the place subject to the noise interference within the allowable range of the state standards for the noise, while the standard for the noise level control is 50~55 dB. In practice the noise reduction device for water falling energy consumption for cooling towers is used for control of the noise source within the tower and sound wave isolation technique is used to control the noise transmission path outside the tower. The previous two approaches can reduce the influence of water falling noise from cooling tower on the environment.
