A system for treating ammonia escape by flue gas fractional denitration and a use method belong to the technical field of atmospheric pollution treatment. The system is formed by fusing an ammonia reduction denitration equipment unit, adopts two-stage different sectional denitration modes in use, and utilizes NH in principle 3 The addition amount is easy to control and NO is oxidized into NO 2 、NO 2 The absorbed and converted characteristics are respectively controlled in the intervention of ammonia reduction primary denitration and purified in secondary oxidation denitration, so as to ensure NH 3 And NO X Ultra-clean emission, and effectively solves the problem of ammonia escape. With first-stage denitration of NH 3 Small dosage, secondary denitration changing waste into valuable, low ammonia operation, low power consumption of dry oxidation denitration, cheap and wide denitration agent, obvious desulfurization capability, easy automatic control and the like, and the secondary oxidation denitration can be carried out on NO X The smoke system with low content is used independently, has the function of adsorbing the smoke desulfurization liquid and moisture, and has positive effect on the whitening of smoke. |
