  冷却塔噪声的治理目标原则上应是将受声点噪声级控制在相应于当地环境的噪声国家标准以内。具体来说,对于冷却塔周围有降噪要求的区域,受声点的噪声级可参照《城市区域环境噪声标准》(GB3096—93>中的二类混合区或工业集中区的环境噪声标准加以控制。此外,由于冷却塔的噪声属于连续均衡、不分昼夜的稳态噪声,因而受声点的噪声控制一般应以夜晚时段的噪声标准为准,这样位于上述二类区域的受声点的噪声控制标准就分别为50dB(A)及55dB(A)。然而对于夜晚无人的受声点,其噪声控制标准应可适当放宽,建议以白天的噪声标准为准,也就是可提升(放宽)10dB,分别为60dB(A)及65dB(A)。

  降低冷却塔噪声的根本措施是从噪声源着手,研制低噪声、超低噪声冷却塔。消声器声屏障以及隔振等亦是可采用的有效方法。

  进风口噪声降幅-般不大于lOdB(A),可采用片式消声器,消声片制成楔形’按福射状排列,撕需消声来设计该片式消声器各个雜,由于进风口面积比排风口大,故流速比排风口小。安装片式消声器后,流速可允许略有增加。在塔体高出周围居民楼群或受噪声污染的居民楼在塔的一侧等特殊情况下,进风口,用声屏障边锋游戏就能满足降噪要求,这样可使装置简化、施工方便,有时进风口亦可用阻性消声通道,例如将冷却塔排风口以下设计成隔声室,再在隔声室某些位置开进风孔,此时只要设计简易的消声通道就能满足降噪要求。
