Flue gas desulfurization and denitrification agent for civil coal-fired cooking stove and use thereof

The invention provides a flue gas desulfurization and denitrification agent for a civil coal-fired cooking stove and a use thereof. The flue gas desulfurization and denitrification agent comprises, by weight, 50 to 90 parts of sodium alkali, 1 to 5 parts of a metal and/or metal oxide additive, 0 to 10 parts of sodium sulfite and 2 to 50 parts of a heat storage material. Through adjustment of the composition and dosage ratio of the flue gas desulfurization and denitrification agent, the flue gas desulfurization and denitrification agent having excellent desulfurization and denitrification performances in the temperature range of civil flue gas. Through combination with a special desulfurization and denitrification device, SO2 and NOx in the flue gas produced by a civil coal-fired cooking heating stove are effectively removed. 本发明提供了种民用燃煤炊事炉用烟气脱硫脱硝剂及其用途，所述脱硫脱硝剂按重量份计包括以下组分：钠剂碱50份～90份、金属和/或金属氧化物添加剂1份～5份、亚硫酸钠0份～10份和蓄热材料2份～50份。本发明通过调整烟气脱硫脱硝剂的组成和用量配比，得到可以在民用烟气温度范围内具有优异脱硫脱硝性能的烟气脱硫脱硝剂，并结合特定脱硫脱硝装置，进而可以有效的脱除民用燃煤炊事采暖炉中烟气
