摘　　要：在硫酸法钛白粉生产中,回转窑是硫酸法工艺的重要设备之一,煅烧是前处理生产的一道重要工序,煅烧尾气也是从回转窑中产生。随着国家环保要求日趋严格,“2+26”城市特别限值排放的要求,对硫酸法钛白煅烧尾气治理也提出了新的要求,这是整个硫酸法钛白行业环保要求的必然趋势,将影响和制约硫酸法钛白工业的可持续发展。主要介绍了目前硫酸法钛白粉煅烧尾气处理的现状及存在问题,并对硫酸法钛白粉煅烧尾气治理下一步的发展进行展望。In the production of titanium dioxide by sulfuric acid process,rotary kiln is one of the important equipments of sulfuric acid process.Calcination is an important process of pretreatment production,and calcination tail gas is also produced from rotary kiln. With the increasingly strict environmental protection requirements of the country and the special limit emission requirements of“ 2+26” cities,new requirements have been put forward for the treatment of titanium dioxide calcination tail gas by sulfuric acid process.This is an inevitable trend of environmental protection requirements for the entire sulfuric acid titanium dioxide industry,which will affect And the sustainable development of the titanium dioxide industry that restricts the sulfuric acid process.This paper introduces the current situation and existing problems of the treatment of titanium dioxide calcination tail gas by sulfuric acid method,and prospects for the next development of sulfuric acid titanium dioxide calcination tail gas treatment.
