摘　　要：随着国家环保政策的日益严格,对钛白粉行业煅烧尾气处理提出了更高的要求,这是整个硫酸法钛白环保要求的必然趋势,将影响和制约硫酸法钛白行业的可持续发展,主要介绍了石灰石石膏法联合钠碱法进行脱硫系统为主的煅烧尾气治理方案,有效降低烟气中的粉尘、SO_(2)、SO_(3)、酸雾等污染物,满足最新的地方及国家排放标准。With the increasingly strict national environmental protection policies,the calcination tail gas treatment in the titanium dioxide industry has put forward higher requirements,which is the inevitable trend of the environmental protection requirements of the whole sulfuric acid titanium dioxide industry,and will affect and restrict the sustainable development of the sulfuric acid titanium dioxide industry.This paper mainly introduces the calcination tail gas treatment scheme based on the limestone gypsum method combined with sodium alkali method for desulfurization system,effectively reducing the dust,SO_2,SO_3 Acid fog and other pollutants meet the latest local and national emission standards.
