冷卻塔噪音清理

冷卻塔降噪具體案例, 根據噪聲來源聲場分布和頻帶特性提出如下降噪方案：
1、為保證冷卻塔的散熱，不能對其進行封閉式隔聲處理，為此設置組合式聲屏障來阻止下部噪聲能量的傳播。
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
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
4、落水的高頻噪聲用超細玻璃棉材料吸收
6、考慮到現場實際情況方案中的所有降噪設施都進行了防塵防潮處理同時不影響冷卻塔的通風和散熱功能。

冷卻塔噪音生產原因

人類對(dui)(dui)改善生(sheng)活環(huan)境要求的(de)日(ri)(ri)益(yi)增長(chang)和水資源的(de)日(ri)(ri)趨(qu)緊(jin)張，是一對(dui)(dui)發(fa)展中的(de)矛盾，冷(leng)卻(que) 塔(ta)實現了(le)冷(leng)卻(que)水循(xun)環(huan)利用，大(da)(da)大(da)(da)減少(shao)了(le)熱(re)交換系(xi)統對(dui)(dui)冷(leng)卻(que)水的(de)消耗。因此，冷(leng)卻(que)塔(ta)在工業和民用建筑等領域得到了(le)廣(guang)泛應用，幵丏為節水事業作(zuo)出了(le)重大(da)(da)貢獻(xian)，但(dan)是它(ta)又產生(sheng)噪(zao)聲(sheng)，對(dui)(dui)環(huan)境造成噪(zao)音污染(ran)。這(zhe)一問題已被國家(jia)和社會充分關注。

噪(zao)(zao)音污染是(shi)一(yi)種(zhong)嚴重的環境(jing)問題(ti)，這是(shi)因為民(min)用(yong)冷(leng)卻(que)塔一(yi)般都安裝在居(ju)民(min)區，所以用(yong)戶 及其周圍居(ju)民(min)都對冷(leng)卻(que)塔的噪(zao)(zao)聲指標提(ti)出了(le)(le)噪(zao)(zao)聲限值要求，為此各地環保局對冷(leng)卻(que)塔產品的生產和使用(yong)做出了(le)(le)嚴格(ge)的限制(zhi)。

冷卻塔降噪標準

《中華人民共和國環境保護法》及《中華人民共和國環境噪聲污染防治條例》，保障城市居民的生活聲環境質量，我國制訂了《社會生活環境噪聲排放標準 GB22337-2008》。
1、城市區域環境噪聲標準限值見表：
2、夜間突發的噪聲，其最大值不準超過標準值15dB。
3、區域及時間的劃定：
(1)、各類標準適用區域由當地人民政府劃定。
(2)、本標準(zhun)晝間、夜間的時間由當(dang)地人民政(zheng)府按當(dang)地習慣和季節(jie)變化劃定。

(時段) 邊界外聲環境功能區	晝間	夜間
0	50	40
1	55	45
2	60	50
3	65	55
4	70	55
