Experimental Study on Removal of Nitrogen Oxides from Flue Gas with High Concentration Organic Wastewater

  • 摘要: 为研发经济、高效的有机废物与烟气NOx协同控制技术,分别采用丙烯酸钠、工业酒精和萘磺酸钠高浓度有机废水替代氨水、尿素等常用脱硝剂,在热态燃煤试验炉上,研究了T(烟气温度)、φ(O2)、停留时间和废水与烟气混合方式等参数对烟气脱硝的影响. 结果表明:在烟气温度为1 190 K时,丙烯酸钠、酒精和萘磺酸钠高浓度有机废水的脱硝效率分别为12.7%、14.2%和9.1%;烟气温度为1 360 K时,三者的脱硝效率分别达到37.6%、39.8%和35.9%;烟气温度高于 1360 K后,脱硝效率下降. φ(O2)从4.1%增至5.2%时,脱硝效率降低了约21.5%、13.1%和15.7%;而φ(O2)升至6.8%时,脱硝效率降至11.2%~13.6%. 丙烯酸钠废水喷射入温度分别为1 185和1 303 K的烟气时,逆向喷入比正向喷入的脱硝效率分别提高30.4%和19.3%;停留时间从0.67 s升至0.82 s时,3类废水脱硝效率分别提高16.0%、18.8%和16.6%.
