Description

technical field [0001] The invention relates to a nanometer sulfur-fixing agent, which belongs to the technical field of air pollution control. Background technique [0002] Coal is one of the main energy sources in my country, and it is also the most commonly used energy raw material in modern industry, but its main utilization method is combustion, and combustion will produce smoke, sulfur dioxide (SO 2 ), NO x and other air pollutants. The acid rain, which is easily formed by these atmospheric pollutants, has caused great harm to the atmospheric environment, seriously affected the quality of human living environment, and destroyed the ecological balance. To solve this technical problem, my country adopts coal-fired sulfur fixation technology to control sulfur dioxide (SO 2 ) emissions to reduce air pollution. [0003] At present, the sulfur fixation technologies of domestic coal-fired power plants include: desulfurization before combustion, sulfur fixation during comb...
