A pilot project of integrated purification technology for hazardous waste incineration flue gas treatment based on catalytic ceramic fiber filter tube

实现烟气多污染物一体化净化成为危废焚烧烟气治理领域的新趋势。提出了基于催化陶瓷纤维滤管的危废焚烧烟气一体化处理工艺,并依托江苏某危险废物焚烧厂建设了中试示范工程,以考察该工艺的处理效果。结果表明:该工程可实现对危废焚烧烟气进行除尘、脱酸、脱硝及降解二恶英等处理的集约、高效运行;其关键技术为催化陶瓷纤维管的应用;运行成本较传统工艺降低了约30%,且具有处理效率更高、占地面积更小、投资和运行费用更低等优点。本示范工程可为现役危废焚烧烟气净化工程的改造及新建项目实现深度净化提供参考。

The realization of integrated purification of flue gas with multi-pollutants has become a new trend in the field of treatment of flue gas from hazardous waste incineration.An multi-pollutants integrated purification technology for flue gas from hazardous waste incineration based on catalytic ceramic fiber filter tube was proposed,and the application of this technology in a pilot project of a waste incineration plant in Jiangsu was introduced to investigate the treatment effect.The result indicated that this technology could realize the intensive and efficient removal of multiple pollutants such as nitrate,dust,acid and dioxin in the flue gas of hazardous waste incineration.The key technology was the application of catalytic ceramic fiber tube.Compared with the traditional process,the operating cost was reduced by about 30%.The ingegrated technology had the advantages of higher proceessing efficiency,smaller footprint,lower incestment and oprating costs.This domenstration project can provide technical support to fully control multi-pollutants in flue gas from hazardous waste incineration.
