目前,制铝生产仍为冰晶石——氧化铝熔盐电解法。在生产过程中,从电解槽散发出大量烟气,烟气由气态和固态物质所组成。其主要成分为HF,其余CO、CO_2SO_2、siF_4及沥青挥发成分等。为防止含氟烟气对工人健康的损害,1978年以来,湖北丹江铝厂逐步采取了综合性防护措施。1981年对电解厂房进行了改造,采用改进型60KA侧插自焙阳板电解槽。1984年进行了系列的技术改造,新建的电解厂房及相应的辅助设施,电解槽为双侧纵向排列,
At present, aluminum production is still cryolite - alumina molten salt electrolysis. In the production process, a large amount of flue gas is emitted from the electrolytic cell, and the flue gas consists of gaseous and solid substances. The main components of HF, the rest of CO, CO_2SO_2, siF_4 and asphalt volatile components. To prevent fluorine-containing fumes from damaging workers’ health, Hubei Danjiang Aluminum Plant has gradually taken comprehensive protective measures since 1978. Electrolysis plant in 1981 to carry out the transformation, the use of improved 60KA side inserted self-baking cell plate electrolyzer. In 1984 a series of technical transformation, the new electrolytic plant and the corresponding ancillary facilities, electrolyzers arranged longitudinally on both sides,
