板式換熱器處理方法：編輯①換熱器流道中的臟物或板片結(jié)垢，對于新運行的系統(tǒng)，根據(jù)實際情況每周清洗一次。清洗板片表面水垢（主要指CaCO3）時，選用含氨基磺酸溶液或含烏洛托品、苯胺、硝酸溶液作為清洗液，清洗溫度4O～6O℃。不拆卸設(shè)備化學(xué)浸泡清洗時，要打開換熱器冷介質(zhì)進(jìn)、出口，或安裝設(shè)備時在介質(zhì)進(jìn)、出口接管上安裝DN25清洗口，將配好的清洗液注入設(shè)備中，浸泡后用清水清洗干凈殘留酸液，使pH≥7。拆開清洗時，將板片在清洗液中浸泡30min。然后用軟刷輕刷結(jié)垢，用清水清洗干凈。清洗過程中應(yīng)避免損傷板片與橡膠墊。若采用不拆卸機(jī)械反沖洗方法，應(yīng)事先在介質(zhì)進(jìn)、出口管路上接一管口，將設(shè)備與機(jī)械清洗車連接，把清洗液按介質(zhì)流動的反方向注入設(shè)備，循環(huán)清洗時間10～15min，介質(zhì)流速控制在～m/s。再用清水循環(huán)幾遍，使清水中Cl質(zhì)量濃度控制在25mg/I以下。②二次循環(huán)水比較好采用經(jīng)過軟化處理后的軟水。一般要求水中懸浮物質(zhì)量濃度不大于5mg/L、雜質(zhì)直徑不大于3mm、pH≥7。當(dāng)水溫不大于95℃時，Ca、Mg濃度應(yīng)不大于2mmol/L；當(dāng)水溫大于95℃時，Ca、Mg濃度應(yīng)不大于0．3mmol/L、溶解氧質(zhì)量濃度應(yīng)不大于0．1mg/L。③對于集中供熱系統(tǒng)，可以采用一次向二次補(bǔ)水的方法。</p></p><br
