烟气湿式氧化脱硝及资源化利用方法
摘要：
本发明涉及一种烟气湿式氧化脱硝及资源化利用方法，包括将含有NOX的烟气通入酸性二价铁溶液中，在0-100℃的温度条件下，吸收NOX生成深褐色的亚硝基亚铁盐、硝酸和亚硝酸的混合液，最终实现烟气脱硝处理。将脱硝的吸收液加入氧化剂，使二氧化氮放出并溶于水、氨水、氢氧化钾或氢氧化钠溶液，生成硝酸，硝酸铵，硝酸钾，硝酸钠等，从而实现资源化利用。
摘要（英）：

The invention relates to a flue gas wet-type oxidation denitration and resource utilization method which comprises the following steps of: leading the glue gas containing NOX into an acid ferrous iron solution; absorbing NOX at 0-100 DEG C to generate a dark brown mixed solution consisting of nitroso ferrite, nitric acid and nitrous acid to finally realize the flue gas denitration processing; and adding an oxidant into the denitration absorption liquid so that the nitrogen dioxide is discharged and dissolved in water, ammonia water, potassium hydroxide or sodium hydroxide solution to generate nitric acid, ammonium nitrate, potassium nitrate, sodium nitrate and the like so as to realize resource utilization.
