  • 矿用燃煤锅炉废气治理……王瑞彦
  • 摘 要:燃煤锅炉在矿山生产中应用广泛,并发挥重要作用,但其产生的废气中含有烟尘、二氧化硫和氮氧化物等有害物质,破坏生态环境,威胁人类健康,加强燃煤锅炉废气治理具有重要意义。介绍了乌山铜钼矿燃煤锅炉废气治理技术,包括布袋除尘、强碱脱硫和SNCR脱硝。治理后的废气中烟尘2.57 mg/m3、二氧化硫266.15 mg/m3、氮氧化物295.91 mg/m3,分别低于新建锅炉大气污染物排放标准50 mg/m3300 mg/m3300 mg/m3,具有良好的经济效益和环境效益,为同类矿山燃煤锅炉废气治理提供参考。

    Treatmentof the exhaust gas discharged by coal boilers in mines……Wang Ruiyan

    AbstractThe coal boiler is widely applied in mine production and plays an importantrole.However,hazardous substance such as the soot,sulfur dioxide and nitrogenoxide contained in the exhaust gas potentially pollutes eco-environment andthreatens human health.Therefore,it is important that the coal boiler exhaustgas be treated.The paper introduced the coal boiler exhaust gas treatmenttechnology of Wushan Copper-Molybdenum Mine,including cloth bag dustcollection,strong alkaline desulfurization and SNCR denitration.The treated gascontains 2.57 mg/m3 dust,266.15 mg/m3 sulfur dioxide and295.91 mg/m3 nitrogen oxide,lower than the 50 mg/m3,300mg/m3 and 300 mg/m3 air pollution emission standards setcorrespondingly for the three by newly built coal boiler.The treatment processcan provide good economic and environmental benefits as well as the basis forcoal boiler exhaust gas treatment of similar mines.
