1、為保證冷卻塔的散熱,不能對其進(jìn)行封閉式隔聲處理,為此設置組合式聲屏障來(lái)阻止下部噪聲能量的傳播.<br /> 2、為有效減少噪聲聲波的繞射，在冷卻塔底部設置吸聲隔聲組合式聲屏障，吸收低頻噪聲<br /> 3、在冷卻塔中部設置阻尼隔聲板和寬頻帶組合式吸聲材料提高中低頻吸聲效果<br /> 4、落水的高頻噪聲用超細玻璃棉材料吸收<br /> <img alt="" src="/uploadfile/kindeditor/image/20230731/20230731092120072007.jpg" /><br /> 5、考慮到現場(chǎng)實(shí)際情況方案中的所有降噪設施都進(jìn)行了防塵防潮處理同時(shí)不影響冷卻塔的通風(fēng)和散熱功能。<br /> 為保證所有噪聲敏感點(diǎn)都在聲屏障的聲影區內,從而獲得佳的降噪效果，根據現場(chǎng)情況和聲學(xué)計算確定聲屏障有效高度為3m，聲屏障采用寬頻帶組合吸聲結構和阻尼隔聲板的組合式結構其中寬頻帶組合式吸聲結構的吸聲特性曲線(xiàn)。<br /> 消聲器選擇現有的阻性消聲器包括直管式、復合式、片式、盤(pán)式和折板式等幾種方式,其中片式消聲器具有消聲量大，阻力較小,導流效果和安裝靈活的特點(diǎn)，因此選擇在風(fēng)機出口處安裝片式消聲器,同時(shí)考慮到噪聲特點(diǎn)在設計時(shí)特別選用了寬頻吸聲材料<br /> <img alt=""
