自然通风冷却塔降噪设计

自然通风冷却塔降噪设计

冷却塔噪音清理

空调冷却塔多用于人流多的场所或住宅区,对噪音的要求非常高。空调冷却塔多采用机械通风式冷却塔,其运转时,水塔噪声来源主要有以下几个方面:
1、风车噪音:
其噪声主要是由机械噪声和流体噪声组成;
2、电机噪声:
其主要电机运转时的电磁声;
3、水滴噪声:
4、通风噪声:
其主要有塔体内外空气流体噪声和塔体共振噪声。

冷却塔降噪标准

《中华人民共和国环境保护法》及《中华人民共和国环境噪声污染防治条例》,保障城市居民的生活声环境质量,我国制订了《社会生活环境噪声排放标准 GB22337-2008》。
1、城市区域环境噪声标准限值见表:
2、夜间突发的噪声,其最大值不准超过标准值15dB。
3、区域及时间的划定:
(1)、各类标准适用区域由当地人民政府划定。
(2)、本标准昼间、夜间的时间由当地人民政府按当地习惯和季节变化划定。

(时段) 边界外声环境功能区 昼间 夜间
0 50 40
1 55 45
2 60 50

噪声治理的三种类型
隔声屏
适用于要求相对较低噪声治理,多用在铁路、高铁、高速公路两侧,或者一些同类型场所,其原理为阻止噪声朝特定方向的传播。
隔声罩
适用于小型噪声源,如特殊用途的小型机器、锅炉房鼓风机、煤矿井下鼓风机等等。
隔声房
最正规的棋牌游戏平台 适用于大型噪声源,如冷却塔噪声、大型风机噪声、机械设备噪声等等。根据噪声源的不同,选择不同类型治理工艺,或其中一种,或几种类型复合使用。
