摘要
采用模拟试验的方式研究了冷却塔淋雨噪声特性随着淋雨高度、淋雨面积和淋雨密度变化的规律。结果表明,淋雨的噪音频段集中在中高音频,且其频谱特性不随上述条件变化而改变;淋雨噪声随淋雨密度和淋雨面积增大有明显变化,淋雨高度变化对淋雨噪声的影响几乎可以忽略。研究结果可供冷却塔淋雨噪声的预报和治理参考。
This experiment studies the rules of the characteristics of cooling tower water drenching noise with the change of drenching water height,area and density.The results show that,the water drenching noise mainly focuses on the middle and high frequency and the spectrum characteristics doesn’t change with the change of the above mentioned conditions,the water drenching noise changes obviously with the increase of density and area,but change little with that of height.The research results can provide references for the forecast and control of cooling tower water drenching noise.
