Helvetica, Arial, sans-serif;font-size:14px;white-space:normal;"> 循環(huán)水在正常運行條件下的水質(zhì)控制，可從緩蝕阻垢控制入手。 </p> <div style="box-sizing:border-box;margin:0px;padding:0px;color:#333333;font-family:"Microsoft YaHei", Helvetica, Arial, sans-serif;font-size:14px;white-space:normal;"> 緩蝕阻垢控制是循環(huán)水處理領域的一項重要課題。通過添加緩蝕阻垢劑，對水系統(tǒng)中的熱交換設備有緩蝕、減少污垢的目的。在低濃度條件下，原水為腐蝕性水，隨著濃度的增大，逐漸變?yōu)榻Y垢水；對此，為確保水處理的持續(xù)性和高效率，需制定兩個防腐層保護方案。 </div> <div

style="box-sizing:border-box;margin:0px;padding:0px;color:#333333;font-family:"Microsoft YaHei", Helvetica, Arial, sans-serif;font-size:14px;white-space:normal;"> 緩蝕控制是低濃度比水處理的重點。通過公式pHs=(9.30+A+B)-(C+D),PSI=2xPHs-PH，可以判斷循環(huán)水垢與腐蝕的關系。 </div> <div style="box-sizing:border-box;margin:0px;padding:0px;color:#333333;font-family:"Microsoft YaHei", Helvetica, Arial, sans-serif;font-size:14px;white-space:normal;"> </div> <div style="box-sizing:border-box;margin:0px;padding:0px;color:#333333;font-family:"Microsoft YaHei", Helvetica, Arial, sans-serif;font-size:14px;white-space:normal;"> HEDP是聚醚部門循環(huán)水處理的緩蝕阻垢劑，其適用水質(zhì)范圍為高PH值、高堿度、高硬度條件下。因為HDEP單獨使用阻垢效果明顯，緩蝕效果較差，在循環(huán)水腐蝕判斷中，車間基本上采用硫酸鋅作為緩蝕劑補充，依靠兩種藥劑的協(xié)同作用來提高水處理的緩蝕效果。循環(huán)水的腐蝕速率控制在0.075毫米/a以下。 </div> <div style="box-sizing:border-box;margin:0px;padding:0px;color:#333333;font-family:"Microsoft YaHei", Helvetica, Arial, sans-serif;font-size:14px;white-space:normal;"> </div> <div

style="box-sizing:border-box;margin:0px;padding:0px;color:#333333;font-family:"Microsoft YaHei", Helvetica, Arial, sans-serif;font-size:14px;white-space:normal;"> 在高濃縮倍數(shù)的條件下，循環(huán)水容易因成垢離子的濃度而結垢。這時，我們應該采取的措施是阻垢。聚醚部循環(huán)水水質(zhì)如表所示，由于黃河水和澧河水作為補給水的變化，要考慮鈣離子+堿度的值是否在900loomg/l范圍內(nèi)，有時黃河水作為補給水水質(zhì)，不適合在高濃度因子下運行，主要是因為經(jīng)濟運行。適當增加緩蝕性阻垢劑的投加量，并加高效阻垢分散劑，是目前聚醚部循環(huán)水處理中所采取的一種有效措施。
