editor">　　在鍋爐的制造、運(yùn)輸、安裝和維修過(guò)程中，不可避免地會(huì)產(chǎn)生一些雜質(zhì)如油污、鐵屑、焊渣、氧化鐵等。這些雜質(zhì)隨鍋爐投入使用，但當(dāng)它們進(jìn)入運(yùn)行系統(tǒng)時(shí)會(huì)對(duì)鍋爐造成很大的危害，所以我們將對(duì)新投入運(yùn)行的鍋爐進(jìn)行清洗，那么，在鍋爐啟動(dòng)前應(yīng)該怎么進(jìn)行鍋爐清洗呢？<br /> 　　鍋爐清洗方法，即機(jī)械除垢和化學(xué)清洗，其中化學(xué)清洗可分為堿煮除垢和酸洗除垢。<br /> 　　一、鍋爐化學(xué)清洗：<br /> 　　原理是利用化學(xué)物質(zhì)的反應(yīng)能力，可以去除難以去除的硬垢和腐蝕產(chǎn)物。鍋爐清洗時(shí)，冷卻設(shè)備不能打開(kāi)，設(shè)備中縫隙小的零件可以清洗，清洗時(shí)間短。<br /> 　　二、鍋爐除垢清洗：<br /> 　　1.機(jī)械除垢<br /> 　　機(jī)械除垢主要采用電動(dòng)洗管機(jī)、平鏟、鋼絲刷、錘子。這種方法相對(duì)簡(jiǎn)單，成本低，但強(qiáng)度大除垢效果差，容易損傷金屬表面。僅適用于積垢面積小、結(jié)構(gòu)簡(jiǎn)單、便于機(jī)械工具接觸水垢的小型鍋爐。<br /> 　　2.堿洗除垢<br /> 　　鍋爐堿煮的作用主要是除去水垢，同時(shí)促使水垢松動(dòng)脫落。單純堿煮除垢效果差往往需要配合機(jī)械除垢。堿煮對(duì)以硫酸鹽和硅酸鹽為主的水垢有一定的作用，但對(duì)于碳酸鹽水垢效果遠(yuǎn)不如酸洗。鍋爐清洗也常用于新安裝鍋爐的除銹脫脂，有時(shí)也用于酸洗或垢型轉(zhuǎn)化前的脫脂清洗。<br /> 　　3.酸洗除垢<br /> <p> 　　目前各種除垢方法中，酸洗除垢效果較好，但如果酸洗工藝不當(dāng)或控制不當(dāng)，也會(huì)影響除垢效果或腐蝕金屬，有時(shí)甚至?xí)?yán)重影響鍋爐的運(yùn)行。酸洗前，應(yīng)提前抽取有代表性的水垢樣品進(jìn)行測(cè)試，并制定清洗方案；進(jìn)酸開(kāi)始時(shí)，腐蝕指數(shù)表要掛在鍋爐和酸箱內(nèi)(取出直至除酸)；酸洗工藝流程、酸洗液的溫度和濃度、流速、酸洗時(shí)間等。應(yīng)根據(jù)清潔方案實(shí)施和控制。在鍋爐清洗過(guò)程中，應(yīng)連續(xù)取樣測(cè)試，并如實(shí)記錄。清洗后，應(yīng)檢查并驗(yàn)收清洗質(zhì)量。
