| 摘 要： | 在自行设计的吸收塔反应器中,以氨水作为吸收剂,研究其对SO2和NOx的脱除效果,在氨法脱硫的工艺条件下对SO2的脱除率为100%,NOx脱除率可达72%。对SO2和NOx的吸收条件进行了研究,发现吸收液中SO32-浓度是影响脱硫脱硝率的重要因素。提出了选择性催化氧化(SCO)和氨法烟气脱硫相结合的氨吸收法同时脱硫脱硝技术,此法可用于改造现有氨法烟气脱硫设备,达到SO2和NOx同时脱除的目的。

| Abstract: | The study on simultaneous desulfurization and denitrification was carried out in a self-designed reactor using ammonia as the absorbent.The removal efficiency of SO2 was 100% and NOx removal rate was 72%.The condition for the absorption of SO2 and NOx was studied.It showed that SO32? concentration in the absorption solution is an important factor for desulfurization and denitrification.The combination of selective catalytic oxidation(SCO)and ammonia flue gas desulfurization were proposed.This method can be used to modify the existing ammonia flue gas desulfurization equipments to achieve simultaneous desulfurization and denitrification. |
