摘要
结合活性焦干法烟气净化技术的优缺点以及现阶段中国燃煤电厂烟气脱硫整体发展水平,分析活性焦干法烟气净化技术应用于中国大型燃煤电厂的适应性;总结了该技术应用于燃煤电厂烟气污染治理需解决的关键问题,如工程造价、对高SO2浓度烟气的适应性、所需物料的供应及脱硫副产物处置及活性焦再生热源等,对于中国高含硫燃煤烟气条件,若采用活性焦干法烟气净化技术,需进行二次技术开发;特别指出,只有研发出中国自主知识产权的可资源化活性焦干法烟气宽谱净化技术,实现技术设备国产化,尤其是吸附塔和解析塔等核心设备的加工制造,才能大幅降低工程造价,使该技术具有较强的技术经济优势而加以推广。
The adaptability of activated coke dry flue gas purification technology applied in large-scale-coal fired power plants are analyzed in combination with tire pros anti cons of the technology anti the present status of flue gas desulphurization in domestic power plains. The key issues need to be solved in the application of the technology are discussed, such as the project costs, the adaptability to high SO2 content, the material supplies, the desulfurization byproduct disposal management and the heat resource for activated coke regeneration. The analysis also indicates that for the high sulfur coal in China, the technology needs to be further developed if applied. In partieular, only the technology suitable for wide-range flue gas with independent intellectual rights is developed and the core equipiments, such as the absorber and the regenerator are manufactured domestically, can the project costs be reduced by a big margin so as to make the technology more advantageous in technical and economic performances and be applied broadly.
