上犹县滤清器厂60年代建厂以来,冲天炉化铁一直把萤石作为造渣材料。由于萤石(主要成分是CaF_2)能与炉中SiO_2、Al_2O_3等组成低熔点多元化合物,加剧对炉壁的侵蚀,更主要的是萤石在高温条件下,产生大量的有毒有害的HF和SiF_4气体外排(HF的危害程度比SO_2大20倍),严重污染环境,影响厂周围群众和职工的身心健康,因冲天炉所排有害气体对厂周围农作物和树木的危害,而产生不同程度的枯黄,经常引起环境污染纠纷。针对上述情况,在厂领导
On the county filter factory 60 years since the plant, Cupola has been to fluorite as slagging material. Fluorite (CaF 2) can form low-melting point compounds with SiO 2 and Al 2 O 3 in the furnace, which aggravates the erosion of the furnace wall. More importantly, fluorite produces a large amount of toxic and hazardous HF and SiF 4 at high temperature The efflux of gas (HF is 20 times more harmful than that of SO 2) seriously pollutes the environment and affects the physical and mental health of the people and workers around the plant. Due to the harmful gas emitted by the cupola on the crops and trees around the plant, different degrees of Yellowish, often causing environmental pollution disputes. In response to the above situation, the factory leadership
