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。
為(wei)(wei)保(bao)證所有噪聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)敏感點都在(zai)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)屏(ping)障的(de)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)影區內，從而獲得最佳的(de)降噪效果，根據現場情況和聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)學計算(suan)確定聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)屏(ping)障有效高度為(wei)(wei)3m，聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)屏(ping)障采用寬頻(pin)帶組(zu)合吸(xi)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)結(jie)(jie)構和阻(zu)(zu)尼隔(ge)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)板的(de)組(zu)合式(shi)結(jie)(jie)構其中 寬頻(pin)帶組(zu)合式(shi)吸(xi)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)結(jie)(jie)構的(de)吸(xi)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)特(te)(te)性(xing)曲線。 消聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)器選擇現有的(de)阻(zu)(zu)性(xing)消聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)器包(bao)括直管式(shi)、復合式(shi)、片(pian)式(shi)、盤式(shi)和折板式(shi)等幾種方式(shi)，其中片(pian)式(shi)消聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)器具有消聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)量大，阻(zu)(zu)力較小，導流效果和安(an)裝靈 活的(de)特(te)(te)點，因此選擇在(zai)風機(ji)出口處(chu)安(an)裝片(pian)式(shi)消聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)器，同時(shi)考慮(lv)到噪聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)特(te)(te)點在(zai)設計時(shi)特(te)(te)別選用了寬頻(pin)吸(xi)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)材(cai)料(liao)

冷卻塔噪音生產原因

人類對(dui)改善生(sheng)活環境要求的(de)(de)日(ri)益增長(chang)和水(shui)(shui)(shui)資源的(de)(de)日(ri)趨(qu)緊張，是一對(dui)發展(zhan)中的(de)(de)矛(mao)盾，冷卻 塔實現了(le)冷卻水(shui)(shui)(shui)循環利用，大(da)大(da)減(jian)少了(le)熱交換系統對(dui)冷卻水(shui)(shui)(shui)的(de)(de)消耗。因此(ci)，冷卻塔在(zai)工(gong)業和民用建筑(zhu)等領域得到了(le)廣泛應(ying)用，幵丏為節水(shui)(shui)(shui)事業作出了(le)重大(da)貢獻，但是它又(you)產(chan)生(sheng)噪聲，對(dui)環境造(zao)成噪音污染。這一問題已(yi)被國家和社(she)會充(chong)分關注。

噪(zao)音污染是一種嚴重的(de)環(huan)境問題(ti)，這(zhe)是因為民(min)用(yong)冷卻塔一般都(dou)安裝(zhuang)在居民(min)區，所以用(yong)戶 及其(qi)周圍居民(min)都(dou)對(dui)冷卻塔的(de)噪(zao)聲(sheng)指標提出了(le)噪(zao)聲(sheng)限(xian)值要求(qiu)，為此各地環(huan)保局(ju)對(dui)冷卻塔產品的(de)生產和使用(yong)做(zuo)出了(le)嚴格的(de)限(xian)制。

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(zhou)間(jian)、夜間(jian)的(de)時(shi)間(jian)由當(dang)(dang)地人(ren)民政府按當(dang)(dang)地習慣(guan)和季節變(bian)化(hua)劃定(ding)。
