摘要
火电行业燃煤烟气是SO_2、NO_x和烟尘的主要来源之一,造成的环境污染非常严重,对人体健康和区域经济发展均产生了不良影响。随着《火电厂大气污染物排放标准》和环境保护部《关于执行大气污染物特别排放限值的公告》的实施,对燃煤烟气的脱硫脱硝一体化处理成为各企业亟待解决的难题。文章着重介绍了某火电厂采用脱硫脱硝一体化技术对原烟气处理系统进行改造的情况,改造后烟气中的SO_2、NO_x、烟尘等指标均实现了稳定达标排放。
Coal-fired gas of thermal power industry is the main-source of SO2 NOx and snake dust, which has serious negative impacts on human health and the regional economic development, has serious environmental pollution. With the implementation of the emission standard of pollutants in thermal power plant and the implementation of Notice on the implementation of special emission limits for atmospheric pollutants, the simultaneous desulfurization and denitrification of coal-fired gas has become a difficult problem, which needs to be solved urgently. The paper focuses on the reconstruction of flue gas treatment system originally existed by using coal-fire gas simultaneous desulfurization and denitrification. The pollutant indexes, such as SO2 NOx. Snake dust. etc, in the effluent of the reconstruction system can reach the emission standard steadily.
