| 摘 要： | 氨法脱硫技术相较其他脱硫技术有较多优势,该技术在高效治理SO2的同时还可得到副产品化肥硫酸铵,但存在副产物硫酸铵晶体颗粒小和结晶率低的问题.因此,本文综述了晶种、Fe3+、添加剂和悬浮物对硫酸铵结晶的影响,分析了各因素对硫酸铵成核的影响机理,总结了当前研究不足,并对硫酸铵结晶未来重点研究方向进行了展望.

| Abstract: | Ammonia desulfurization technology has many advantages compared with other desulfurization technologies. This technology can effectively control SO2 and also obtain by-product fertilizer ammonium sulfate, but it has the problems of small by-product ammonium sulfate crystal particles and low crystal formation rate. Therefore, the effects of seed crystals, Fe3+, additives and suspended solids on the crystallization of ammonium sulfate were reviewed. The mechanism of various factors on the nucleation of ammonium sulfate was analyzed. The current research deficiencies were summarized, and the key research direction of ammonium sulfate crystallization in the future was prospected. |
