氢氧化铝焙烧烟气脱硝工艺的探讨

Exploration on Denitration Process of Aluminium Hydroxide Calcinator Flue Gas

文章简要概括了烟气脱硝技术的现状,针对氢氧化铝焙烧炉烟气的特点,指出了采用SNCR+SCR联合的脱硝技术脱除焙烧烟气中氮氧化物,该技术在不大幅改动氢氧化铝焙烧炉主体结构的前提下,可使氢氧化铝焙烧烟气中的氮氧化物含量满足超低排放的标准,并以此分析了该技术的特点及适用性。

This paper briefly introduces the status of flue gas denitration technology,according to the characteristic of the flue gas of aluminum hydroxide calcinator,it points out that the denitration technology of SNCR combining with SCR is used to remove the nitrogen oxide content in flue gas.The technology ensures ultra-low nitrogen oxide content in flue gas as the emission standards stipulate without significant renovation in major calcinator structure.In addition,the characteristics and applicability of the technique are analysed.
