style="text-indent:25px">列管式冷卻器清洗：1、物理清洗辦法：固定管板式的可以用水泵刷子沖洗，如果是抽芯式即浮頭式的即可把管束抽出來(lái)沖洗；2化學(xué)清洗：方法當(dāng)積垢由疏松變?yōu)橹旅堋⒂操|(zhì)后，采用機(jī)械清洗方法己達(dá)不到清垢目的，此時(shí)宜采用酸洗的方法。鹽酸不用預(yù)熱就能容易地溶解碳酸鈣和碳酸鎂水垢，因此酸洗液一般為常溫鹽酸溶液。酸洗雖然能很好的疏松水垢和恢復(fù)冷卻器表面的正常狀態(tài)，但鹽酸對(duì)冷卻銅管有腐蝕作用。為了保護(hù)冷卻器管壁不受鹽酸的侵蝕，在酸洗液內(nèi)必須加入添加劑，即強(qiáng)烈地遲滯金屬溶解過(guò)程的物質(zhì)。我們選用的添加劑為苯駢三氮唑，即BC-801水穩(wěn)定劑，使用濃度為3%左右。根據(jù)經(jīng)驗(yàn)，若能夠按時(shí)進(jìn)行機(jī)械清洗，酸洗可2a--3a進(jìn)行1次；反之，需每年進(jìn)行1次酸洗。</p><div
