【摘要】 烧结烟气是钢铁行业的主要污染物,成为钢铁企业SO₂减排的重点,减排形势日趋严重,而随之产生的大量脱硫灰的综合利用成为急需解决的问题。介绍了烧结烟气脱硫灰的产生、特性以及污染现状,总结了当前国内外对脱硫灰综合利用的现状和利用过程中存在的问题,并提出了烧结烟气脱硫灰用作新型胶凝材料或者复合微粉的新途径,从而使之变废为宝。更多还原

【Abstract】 Sintering flue gas have became focal point in SO₂ dischange at iron and steel industry, It is more serious to decrease SO₂,and the comprehensive utiliza-tion of the large amount of desulfurization ash has become an urgent task.The formation,the characteristic and the pollution situation of sintering flue gas desulfurization ash is analyzed,current comprehensive utilization of semi -dry desulfurization ash from sintering flue gas and problems from the processes of comprehensive utilization are summarized,the new utilization of the desulfurization ash to produce the new type of ce-menting materials or compound powder is put forward.更多还原
