Abstract

Abstract:

Driven by the concept of green ecology and sustainable development strategy, exhaust emissions to the environment has attracted much attention. As one of the main pollutants of exhaust gas, NO _x is the focus and difficulty of exhaust gas pollutant control. The advantages, disadvantages and application status of traditional post-treatment de-NO _x technologies are introduced. The basic researches of dielectric barrier discharge are reviewed. The synergistic de-NO _x performance and mechanism by DBD and catalyst are analyzed. It is pointed out that:①the DBD power supply and the reactor structure are the key factors restricting the de-NO _x performance; ②the de-NO _x performance of DBD only is not satisfactory, but the combination of DBD with catalytic packed bed exhibits excellent de-NO _x efficiency and high N₂ selectivity; ③the researches on de-NO _x mechanism of plasma-assisted catalyst mainly include plasma characteristic parameter diagnosis, fluid model verification, plasma propagation mechanism analysis and in-situ characterization. However, the research on the theoretical calculation of plasma catalysis is limited. Therefore, we propose that the future development of DBD de-NO _x technology should be based on ①the high-power and high-efficiency power supply to improve the NO _x treatment capacity; ②the reactor structure optimization to improve the de-NO _x efficiency and N₂ selectivity; ③suitable design and construct of the de-NO _x catalyst for DBD environment; ④the comprehensive analysis of the de-NO _x mechanism of DBD synergistic catalyst.

Key words: dielectric barrier discharge, catalyst, packed bed, selectivity, de-NO _x mechanism

摘要：

受绿色生态和可持续发展战略理念的驱动，废气排放对环境造成的危害备受关注。NO _x 作为废气的主要污染物之一，是废气污染物控制的重点与难点。基于此，本文介绍了传统后处理脱硝技术的优缺点及应用现状,回顾了介质阻挡放电（DBD）基础研究，分析了DBD脱硝性能，重点阐述了DBD协同催化剂脱硝及脱硝机理。分析指出：①DBD驱动电源与反应器结构是制约脱硝性能的关键因素；②单独DBD技术脱硝性能较差，而DBD协同催化填充床技术展现出优异的脱硝性能和较高的N₂选择性；③等离子体协同催化脱硝机理研究主要包括等离子体特征参数诊断、流体模型验证、等离子体传播机制分析以及原位表征，而在等离子体催化理论计算方面的研究较为缺乏。因此，未来DBD协同催化脱硝技术应立足如下几个方面发展：研发高功率、低能耗电源，提升废气NO _x 处理量；优化反应器结构，提升脱硝的效率与选择性；设计与构筑适宜于DBD环境的脱硝催化剂；深入全面分析DBD协同催化剂脱硝机理。
