一、什么是工業冷卻水?

化學(xue)工業、石油(you)工業、冶金工業及(ji)建筑(zhu)的空調(diao)系統中常需要將熱(re)工藝介(jie)質(zhi)進行冷(leng)卻，水的特性很適合用(yong)作(zuo)冷(leng)卻介(jie)質(zhi)。工業冷(leng)卻水通過換熱(re)器(qi)(或(huo)稱熱(re)交換器(qi)、水冷(leng)卻器(qi)、水冷(leng)器(qi))與工藝介(jie)質(zhi)間接換熱(re)。熱(re)的工藝介(jie)質(zhi)在熱(re)交換過程中降低溫(wen)(wen)度(du)，冷(leng)卻水被(bei)加熱(re)而溫(wen)(wen)度(du)升高(gao)。工業冷(leng)卻水的用(yong)量(liang)往往很大，在化學(xue)工業許多(duo)企業中占到工業用(yong)水總量(liang)的90%~95%以上。因此要進行回收循環使用(yong)。

二、冷卻水系統常分為幾種類型？

冷卻水系統基本可分為(wei)直流水系統和(he)循(xun)環水系統。

在(zai)直流水(shui)(shui)(shui)(shui)(shui)系(xi)統(tong)中(zhong)，冷卻水(shui)(shui)(shui)(shui)(shui)只(zhi)經換熱(re)器(qi)一(yi)次(ci)利用(yong)(yong)后就被排(pai)掉了(le)，所以(yi)直流水(shui)(shui)(shui)(shui)(shui)又稱為一(yi)次(ci)利用(yong)(yong)水(shui)(shui)(shui)(shui)(shui)。直流冷卻水(shui)(shui)(shui)(shui)(shui)系(xi)統(tong)通(tong)常(chang)用(yong)(yong)水(shui)(shui)(shui)(shui)(shui)量(liang)很大(da)，水(shui)(shui)(shui)(shui)(shui)經換熱(re)器(qi)后的(de)(de)溫(wen)升(sheng)較(jiao)小，而排(pai)出水(shui)(shui)(shui)(shui)(shui)的(de)(de)溫(wen)度也(ye)較(jiao)低(di)，水(shui)(shui)(shui)(shui)(shui)中(zhong)的(de)(de)含鹽(yan)量(liang)基本上不濃縮。一(yi)般只(zhi)有(you)在(zai)具有(you)可供(gong)大(da)量(liang)使(shi)用(yong)(yong)的(de)(de)低(di)溫(wen)水(shui)(shui)(shui)(shui)(shui)，并且 水(shui)(shui)(shui)(shui)(shui)費(fei)便(bian)宜的(de)(de)地區采(cai)用(yong)(yong)這種系(xi)統(tong)。

但由于排水(shui)對(dui)環境的污染(ran)問題(ti)， 所以現在即使在水(shui)量(liang)豐富的地(di)區也不提倡采用直流水(shui)系(xi)統(tong)。

在循壞水(shui)(shui)系(xi)沉中(zhong)，冷卻水(shui)(shui)可以反復(fu)使(shi)用(yong)(yong)。水(shui)(shui)經換熱器后溫(wen)度升高，由冷卻塔或其(qi)他(ta)冷卻設備將水(shui)(shui)溫(wen)降(jiang)低下來(lai)，再由泵將水(shui)(shui)送往用(yong)(yong)戶，水(shui)(shui)在如此不斷地進(jin)行重復(fu)使(shi)用(yong)(yong)，所以采用(yong)(yong)循環水(shui)(shui)系(xi)統(tong)可提高水(shui)(shui)的重復(fu)利用(yong)(yong)率。隨著節約(yue)用(yong)(yong)水(shui)(shui)的需要，許(xu)多工業正(zheng)逐漸轉向(xiang)采用(yong)(yong)循環水(shui)(shui)系(xi)統(tong)。
