双碱法在烧结机烟气脱硫中的应用

Application of Double Alkaline in Sintering Machine Flue Gas Desulfurization

在我国因SO2排放而形成的酸雨危害日益严重，每年造成数千亿的经济损失，SO2及酸雨污染已经成为制约我国经济和社会发展的重要因素。而钢铁企业是国家重点的基础产业，产生的SO2约占全国排放量的10%以上，其中烧结工序中排放总量约占钢铁企业排放总量的50~60o，解决好烧结工序SO2的减排，就是抓住了钢铁行业SO2减排工作的重点。

Acid rain damage due to SO2 emissions is increasing serious in China, resulting in hundreds of billions economic losses each year. SO2 and acid rain pollution have become important factors in China＆#39;s economic and social development. The steel industry is a national key basic industries, the SO2 emissions accounting for over 10% of China, wherein the total emissions of the sintering process accounting for about 50~60% of total emissions from the enterprise. Solving well the sintering process of SO2 reduction will seize the key point of steel industry SO2 emission reduction work.
