摘　　要：主要介绍了气动脱硫技术,以石灰石作为吸收剂,在吸收塔内加装气动脱硫单元和高效除雾器,不加装塔内托盘和湿式电除尘装置就可以高效的脱除燃煤发电厂烟气中的SO_2、尘等污染物。结果显示,此超低排放技术可显著降低大气污染物排放水平。Usage of pneumatic desulphurization technology is mainly described. Limestone as an absorbent, S02, dust and other pollutants in flue gas can be efficiently desulphurized and removed when the pneumatic desulphurization units and efficient defogger were installed in the desulphurization tower, instead of perforated plate and wet electrostatic precipitator. The results show that pollu-tants emission decreases obviously by the ultra-low emission technology in power plant
