烟道气脱硫脱硝一体化技术研究进展

摘要

Smoke from the burning coal boiler is one of the main reasons of air pollution, and its main composition are S02 and NOx. But the two catalytic process of desulfurization denitrification influence each other, so the desulfurization denitrification integration technology is the treatment direction of flue gas. According to different mechanisms, the flue gas desulfurization denitrification integration technology are divided into two types: combined SOJNO removal and simultaneous SOJNO removal. The paper reviewed the development of integration process at home and abroad.%燃煤锅炉烟道气产生的烟尘是造成大气污染的主要原因之一,其主要成份是有害的SO2和NOX。但是脱硫脱硝两个催化过程相互影响,所以烟道气治理的发展方向是脱硫脱硝一体化技术。按机理的不同,将烟道气脱硫脱硝一体化技术分为两类：联合脱硫脱硝技术和同时脱硫脱硝技术,文章综述了目前国内外开发的各种一体化工艺。
