style="text-indent:25px">開(kāi)式冷卻塔合理布局就是實(shí)現(xiàn)功能分區(qū)，動(dòng)靜分開(kāi)。冷卻塔由于噪聲源強(qiáng)較大，宜布置在生產(chǎn)區(qū)或者活動(dòng)區(qū)等噪聲要求較低的區(qū)域。避免距離辦公室、宿舍、居住區(qū)等噪聲敏感建筑物太近，影響職工和居民的工作。不同功能區(qū)之間設(shè)置噪聲防護(hù)距離，環(huán)境噪聲較高的功能區(qū)內(nèi)靠近噪聲源側(cè)安排噪聲要求相對(duì)不高的建筑或房間。主要是隔絕設(shè)備的振動(dòng)，以減弱設(shè)備振動(dòng)對(duì)結(jié)構(gòu)的影響。在滿足換風(fēng)系數(shù)的條件下，在冷卻塔外側(cè)設(shè)置隔聲設(shè)施冷卻塔外罩，一般情況下，隔聲措施的可以達(dá)到156的效果。</p><p style="text-indent:25px">開(kāi)式冷卻塔的冷卻原理就是，通過(guò)將循環(huán)水以噴霧方式，噴淋到玻璃纖維的填料上，通過(guò)水與空氣的接觸，達(dá)到換熱，再有風(fēng)機(jī)帶動(dòng)塔內(nèi)氣流循環(huán)，將與水換熱后的熱氣流帶出，從而達(dá)到冷卻。此種冷卻方式，首期的投入比較的少，但是運(yùn)營(yíng)成本較高（水耗、電耗）。2.閉式冷卻塔的冷卻原理是，簡(jiǎn)單來(lái)說(shuō)是兩個(gè)循環(huán)：一個(gè)內(nèi)循環(huán)、一個(gè)外循環(huán)。沒(méi)有填料，主重心部分為紫銅管表冷器。①內(nèi)循環(huán)：與對(duì)象設(shè)備對(duì)接，構(gòu)成一個(gè)封閉式的循環(huán)系統(tǒng)（循環(huán)介質(zhì)為軟水）。為對(duì)象設(shè)備進(jìn)行冷卻，將對(duì)象設(shè)備中的熱量帶出到冷卻機(jī)組。開(kāi)式冷卻塔的這種冷卻方式，水耗和電耗是比較大的，也就是說(shuō)運(yùn)營(yíng)成本會(huì)比較高。</p><div
