冷却塔噪音如何降低?

冷却塔噪音如何降低?

冷却塔在选用的环节中,考虑到离心水泵、排风机和冷却循环水不间断的选用,造成冷却塔噪音干扰相当大。噪音主要是考虑到振动的形成的,冷却塔的噪音具体这几个因素:淋水声、排风机风噪声音、离心水泵震动声音。冷却塔噪音共震的干扰区域相当大,能够 制定到周边30-50米内,加消声瓦和隔音屏障后进入60-70dB,因而,冷却塔的噪音干扰是较为严重的。而冷却塔噪音处理的形式具体有:阻隔噪音传递、提升消音棉、改换低转数的排风机等形式。

1、冷却塔降噪处理屏障选择:冷却塔降噪处理所需用的屏障,应当依据具体情况开展选用。较为普遍的就是说墙体、玻璃钢和铝合金。墙体以沙面制定,表面杂点比较多,能够 将声音不一样的方向的散射,而且墙体的使用期限是相当靠谱的。铝合金和玻璃钢表面较为光洁,因而应当制定相应的弧型面。将声音较大 水平的往下散射。飘浮式落水消能降噪处理设备具体由选用挤拉、注塑或热压成型的塑料件或玻璃钢件(受力件)组成。其材料特性是构造轻型、有利于运送、便于安装、防腐耐用。

假如费用预算较为充裕,能够 考虑到可以直接改换大风叶低转数的排风机来减低噪音。或者是在离心水泵和排风机的出风口安装消声屏,消声屏的降噪处理区域在20-30分贝。离心水泵能够 在离心水泵的外面制定消音棉,消音棉可以相当合理有效的减低噪音,而且还不会干扰离心水泵的散热。假如冷却塔制定在室外,那么具体就是说上述的形式开展降噪处理,假如冷却塔制定在室内,能够对室内设计隔音处理,制定在室内,能够选用冷却塔隔音降噪涂料。
