摘要

非热等离子体烟气脱硝的主要问题是能耗偏高，然而适当设置烟气的条件参数，有可能尽量地降低能耗.其中烟气所含SO2和外加NH3产生的降低能耗或提高脱硝率的效果被广泛关注.本文采用CSTR模型，对非热等离子体烟气脱硝的化学反应过程进行数学模拟.从原理上证实了SO2和外加NH3产生的增效不是SO2的贡献，而是外加NH3的效果，同时，讨论了温度的效应.本研究为燃煤电厂烟气净化流程中的非热等离子体脱硝段的设置及调质剂的使用提供理论参考.

Abstract

The main problem in non-thermal plasma flue gas denitrification is overly high energy cost.However，if the conditional parameters are set appropriately the energy cost can be reduced to a lowest possible value.In these respects the effects of the SO2 content in the gas and the ammonia applied to the gas are widely noticed.In this work a CSTR model was adopted to simulate the chemical reaction processes in non-thermal plasma flue gas denitrification.It was proved in principle that the effects of SO2 and addition on energy reduction were not initiated by SO2，but contributed by the externally added NH3.Meanwhile the effect of temperature was also discussed.This work could serve as a theoretical reference for the setup of the non-thermal plasma flue gas denitrification stage and applying the ammonia reagent.
