摘要
针对陶瓷催化滤管烟气污染物一体化脱除技术,介绍了脱硫、脱硝、除尘原理与特点,分析了该技术的研究现状和工业应用情况。分析认为:该技术具有工艺流程短、系统简单、运行成本低、无二次污染等优点,但投资成本高,对于单台40 t/h燃煤锅炉,该工艺的设备投资是传统工艺的1.5~2倍;成熟的商业化陶瓷催化滤管采用钒钛系脱硝催化剂,该催化剂工作温度区间为350~420℃,脱硫、除尘、脱硝过程都是在高温烟气中进行。
Based on the integrated removal technology of flue gas pollutants by ceramic catalytic filter tube,the principle and characteristics of desulfurization,denitrification and dust removal were introduced.The research status and industrial application of this technology were analyzed.The analysis founds that this technology has the advantages of short process flow,simple system,low operation cost and no secondary pollution.However,the equipment investment cost of this technology is 1.5~2 times of that of traditional process for a 40 t/h coal-fired boiler.The mature commercial ceramic catalytic filter tube adopts V-Ti denitrification catalyst with the working temperature range of 350~420℃,so the process of desulfurization,dust removal and denitrification are all carried out in high temperature flue gas.
