铝电解槽废炭块处理
disposal of waste carbon piece of aluminium electrolytic cell
旧d lanJ一eeao fe一tankuol ehul-铝电解槽废炭块处理(disposal of waste ca卜bon pieee of aluminium eleetrotytie eell)消除铝电解槽大修时排出的废阴极炭块中的有害物质对环境的污染，并使其中的有价组分得到综合利用的过程。当用冰晶石熔盐电解法生产金属铝时，电解质中的氟、钠等会逐渐渗透到阴极炭块的微孔中，使其密度增大，体积膨胀而导致槽体变形损坏，当电解槽使用3一4a后，需大修拆除废炭块。每电解h铝排出废炭块约42kg。废炭块的主要化学成分(%)为:C 51.24%，F8 .77%，NaZO 17.35%，AI:03 7.85%，CaO 3.25%，510:3.54%。 由于铝电解槽废炭块含氟等有害物质，遇水后有毒物溶出造成对环境的污染。中国山东铝厂，对电解槽大修时拆除的废炭块进行了处理和利用。将除杂、破碎的废炭块随同无烟煤进人烧结法氧化铝生产的生料浆中，代替部分无烟煤作脱硫剂，同时回收了铝、钠、炭等有用组分。 (宋佩洪)
