摘要: 采用黄磷乳浊液为吸收剂,考察了黄磷浓度、反应温度、搅拌速度、氧气浓度、烟气流量等影响因素对脱硝率的影响,并且通过添加碳酸钙进行改性,提高了体系的脱硝率。结果表明,脱硝率随黄磷浓度增大、反应温度升高、搅拌速度增大而升高;随烟气流量的增大而下降;加入碳酸钙改性可以明显提高体系脱硝效果;烟气流量400mL/min,反应温度50℃,搅拌速度1 200r/min,氧气浓度12%,黄磷浓度6g/L,碳酸钙浓度2g/L的条件下,处理NO浓度为0.06%的烟气,反应30min体系脱硝率可达到84.76%。

Abstract: In this research, by use of yellow phosphorus emulsion as absorbent, influences of the factors such as yellow phosphorus concentration, reaction temperature, stirring rate, oxygen concentration and gas flow rate on denitrification rate are investigated. Furthermore, modification is performed by addition of calcium carbonate to improve the denitrification efficiency of the system. The results show that the denitrification efficiency rises with the increase of yellow phosphorus concentration, reaction temperature and stirring rate, but decreases with the increase of flue gas flow rate. Denitrification efficiency of the system is obviously improved by addition of calcium carbonate for modification. Under the conditions that flue gas flow rate is 400 mL/min, reaction temperature is 50℃, stirring rate is 1 200 r/min, oxygen concentration is 12%, yellow phosphorus concentration is 6 g/L and calcium carbonate concentration is 2 g/L, the denitrification efficiency of the flue gas with NO concentration of 0.06% can reach to 84.76% after 30 minutes of reaction.
