  • 摘要: 采用隔膜电解技术对海水进行改性,生成的氧化液和碱性液分别喷淋进入氧化洗涤塔和碱式吸收塔,通过耦合的二段式反应研究脱除模拟船舶尾气中NO与SO2的性能,实验详细考察了NO与SO2的气体流量与初始浓度、海水电解时间和氧化液有效氯浓度对SO2和NO脱除效率的影响。结果表明:隔膜电解海水能够高效地脱除船舶尾气中的SO2和NO;SO2脱除效率高,在实验条件范围内几乎不受各因素的影响;NO脱除效率随NO初始浓度、海水电解时间、氧化液有效氯浓度的提升而增大,随SO2初始浓度、气体流量的提升而减小。当气体流量为1 m3·h-1,初始SO2、NO浓度分别为600 mL·m-3和900 mL·m-3,海水电解时间为60 min,氧化液有效氯浓度为540 mg·L-1时,模拟船舶尾气中SO2和NO的去除效率可以分别达到98.6%和84.4%。
