超低排放限值下的干熄焦环境除尘改造技术研究

The technology study of dust-catching environment for CDQ under ultra-low emission limit

为满足当地的环保排放标准和厂区合理布置的要求,分析了干熄焦环境除尘脱硫工艺,即钠基干法(SDS)脱硫和石灰石-石膏法湿法脱硫,探讨在超低排放的要求下干熄焦环境除尘脱硫工艺的技术可行性和适用条件,为今后的工程项目设计提供思路。

In order to meet the local environmental emission standards and the requirements of rational plant layout, two desulphurization processes of CDQ environmental dust removal are analyzed: sodium-based dry desulphurization(SDS) and limestone-gypsum wet desulphurization. The technical feasibility and applicable conditions of CDQ environmental dust removal and desulphurization process under the requirement of ultra-low emission are discussed for the future. Engineering project design provides ideas.
