摘要: 相比于传统的选择性催化还原(SCR)和选择性非催化还原(SNCR),湿法烟气脱硝技术(WFGD)能够实现在较低温度下(< 100 ℃)高效脱除烟气中的氮氧化物(NOx)。本研究将实验室自制的新型有机含硫化合物用于WFGD低温烟气脱硝技术,通过实验室小试和1 000 N · m3 · h-1的工业侧线中试实验系统考察并验证了其低温脱硝性能和工业应用潜力。通过气相色谱-质谱分析了自制的有机含硫化合物主要的含硫有机组分,并通过对比实验确定了主要的活性成分为有机亚砜类化合物,同时其他有机含硫物种的存在能够进一步提高脱硝效率。离子色谱分析表明,所考察的脱硝剂主要通过将烟气中的NOx转化为亚硝酸根离子来达到烟气净化的目的。本研究从实验室小试到中试放大侧线实验多个尺度验证了自制的新型有机含硫化合物的低温烟气脱硝工艺的工业应用可行性。

Abstract: Compared with traditional selective catalytic reduction (SCR) and selective non catalytic reduction (SNCR), wet flue gas denitrification (WFGD) technology can effectively remove nitrogen oxides (NOx) from flue gas at a lower temperature (<100 ℃). In this study, the new organic sulfur compounds made in the laboratory were used in WFGD low-temperature flue gas denitration technology, and their low-temperature denitration performance and industrial application potential were systematically investigated and verified through laboratory pilot test and 1 000 N · m3 · h-1 industrial side line pilot test. The main sulfur containing organic components of self-made organic sulfur compounds were analyzed by gas chromatography-mass spectrometry, and the main active components were identified as organic sulfoxide compounds through comparative experiments. At the same time, the presence of other organic sulfur containing species could further improve the denitration efficiency. Ion chromatography analysis showed that the denitration agent investigated mainly achieved the goal of flue gas purification by converting NOx in flue gas into nitrite ions. This research verified the feasibility of industrial application of the self-made low temperature flue gas denitration process of new organic sulfur compounds on multiple scales from laboratory pilot scale to pilot scale side line experiment, and provided new ideas and application guidance for promoting the implementation of efficient low temperature WFGD industrial technology.
