清除電蒸汽鍋爐水垢的幾種方法

電蒸汽鍋爐鍋爐應以防垢為主,其水質須因爐、因水制宜地進行處理,并達到國家標準,以防結垢,這是積板的方法,但如果電蒸汽鍋爐結生了水垢,也應及時清除,以免事故后患。
Electric steam boiler boiler should be based on scale prevention primarily, the water must be processed by furnace, because the local water condition, and reached the national standard, in order to prevent scaling, this is the method of laminated plate, but if the electric steam boilers of the scale, should also be timely cleared, in order to avoid accident trouble.

1、電蒸汽機械除垢。主要采用洗管器、刮刀、鏟刀等工具,有時還配合水力沖洗進行機械清除。此法比較簡單,成本低,但勞動強度大,除垢效果差,易損壞金屬表面,只適用于除垢面積小,且結構簡單便于機械工具鏟到水垢的中小型蒸汽鍋爐。
1, electric steam mechanical descaling. Mainly use the washer, blade, blade tools, sometimes with water flushing for mechanical removal. This method is relatively simple, the cost is low, but high labor intensity, the descaling effect is poor, the metal surface is easily damaged, only suitable for descaling area is small, and is simple in structure and convenient to machine tool shovel to scale steam boiler.


2、堿洗除垢。用磷酸三鈉、燒堿、純堿等堿性藥物進行煮爐清洗,其作用主要是松動水垢并促使其脫落,堿洗除垢常與機械除垢配合進行。
2, alkali cleaning descaling. With three sodium phosphate, caustic soda, soda ash and other basic drugs for boiling furnace cleaning, its main function is to loose scale and promote its shedding, alkali cleaning descaling cooperating with mechanical descaling of.


3、酸洗除垢。常用鹽酸加緩蝕劑,有時還加入氟化物、表面活性劑等添加劑,進行酸洗。酸洗對碳酸鹽水垢和鐵銹垢除垢較徹底,對硫酸鹽和硅酸鹽垢作用較差,需配合堿煮轉型進行除垢。
3, the acid pickling descaling. Commonly used hydrochloric acid and inhibitor, sometimes adding fluoride, surface active agent and other additives, pickling. Pickling of carbonate scale and rust fouling thoroughly, the role of sulfate and silicate scale is poor, to be with the alkali boiling transition of descaling.


需注意的是,如果有并列運行的電蒸汽鍋爐與電熱水鍋爐,不管采用何種方法,在進行除垢前都必須將與之相連接的所有汽、水管道可靠地隔絕,這樣做以提高安全系數。
It must be noted that, if the parallel operation of the electric steam boiler and electric water boiler, regardless of the method, must be all steam, water pipeline isolate reliably connected with the former in descaling, do so in order to improve the safety coefficient.
