一、什么是工業冷卻水?

化學(xue)工(gong)(gong)業(ye)(ye)(ye)、石油工(gong)(gong)業(ye)(ye)(ye)、冶金工(gong)(gong)業(ye)(ye)(ye)及建(jian)筑的(de)空(kong)調系統中常(chang)需要(yao)將熱工(gong)(gong)藝(yi)介(jie)質進行冷卻(que)，水(shui)的(de)特性很適合用作冷卻(que)介(jie)質。工(gong)(gong)業(ye)(ye)(ye)冷卻(que)水(shui)通過換熱器(或(huo)稱熱交(jiao)換器、水(shui)冷卻(que)器、水(shui)冷器)與工(gong)(gong)藝(yi)介(jie)質間接換熱。熱的(de)工(gong)(gong)藝(yi)介(jie)質在(zai)熱交(jiao)換過程中降低溫度，冷卻(que)水(shui)被加熱而(er)溫度升高。工(gong)(gong)業(ye)(ye)(ye)冷卻(que)水(shui)的(de)用量往(wang)往(wang)很大，在(zai)化學(xue)工(gong)(gong)業(ye)(ye)(ye)許多(duo)企業(ye)(ye)(ye)中占到工(gong)(gong)業(ye)(ye)(ye)用水(shui)總量的(de)90%~95%以上。因此要(yao)進行回收循環使(shi)用。

二、冷卻水系統常分為幾種類型？

冷卻水系(xi)統(tong)基本(ben)可分為(wei)直(zhi)流水系(xi)統(tong)和循環水系(xi)統(tong)。

在直流水(shui)系統中，冷(leng)卻水(shui)只經(jing)換(huan)熱器(qi)一(yi)次利用后就被排掉了(le)，所以直流水(shui)又稱為一(yi)次利用水(shui)。直流冷(leng)卻水(shui)系統通常用水(shui)量(liang)很大，水(shui)經(jing)換(huan)熱器(qi)后的(de)溫(wen)升較小，而(er)排出(chu)水(shui)的(de)溫(wen)度也較低，水(shui)中的(de)含鹽(yan)量(liang)基本(ben)上不濃縮。一(yi)般只有在具有可供(gong)大量(liang)使用的(de)低溫(wen)水(shui)，并且 水(shui)費便宜的(de)地(di)區采(cai)用這種(zhong)系統。

但由于排(pai)水(shui)對環境的污染問題， 所以(yi)現(xian)在即使在水(shui)量(liang)豐富的地區也不提倡采用直流水(shui)系(xi)統(tong)。

在循(xun)壞水(shui)(shui)(shui)(shui)(shui)系沉中，冷卻水(shui)(shui)(shui)(shui)(shui)可以反復使用(yong)(yong)。水(shui)(shui)(shui)(shui)(shui)經換熱器后溫度升高，由(you)冷卻塔(ta)或其他(ta)冷卻設(she)備將(jiang)水(shui)(shui)(shui)(shui)(shui)溫降低下來，再由(you)泵將(jiang)水(shui)(shui)(shui)(shui)(shui)送往(wang)用(yong)(yong)戶，水(shui)(shui)(shui)(shui)(shui)在如(ru)此不斷地進(jin)行重(zhong)(zhong)復使用(yong)(yong)，所以采(cai)用(yong)(yong)循(xun)環(huan)水(shui)(shui)(shui)(shui)(shui)系統可提(ti)高水(shui)(shui)(shui)(shui)(shui)的(de)重(zhong)(zhong)復利用(yong)(yong)率(lv)。隨著節(jie)約(yue)用(yong)(yong)水(shui)(shui)(shui)(shui)(shui)的(de)需要，許多(duo)工業正逐漸轉向采(cai)用(yong)(yong)循(xun)環(huan)水(shui)(shui)(shui)(shui)(shui)系統。
