本文提出了一种利用电解海水进行湿式净化去除模拟船舶排放物中NOx和SO2的方法。在半连续鼓泡床反应器中考察了影响NO和NO的去除率的几个因素。结果表明，活性氯浓度、NO入口浓度、反应温度和共存气体（CO2和O2）浓度的增加有利于NOx的脱除，而气体流量的增加则抑制了NOx的脱除。电解海水的pH值对NOx的去除有显著影响。在此基础上，对单级和双级反应器同时脱除NOx和SO2进行了初步研究。在最佳条件下，对模拟船舶排放物（NOx 1000 ppm，O215%，CO25%，SO2751 ppm）中NOx和SO2的最大去除率分别为92%和100%。采用离子色谱法对工艺出水的最终产物（NO2-和NO3-）进行了分析，并对反应途径进行了探讨。
This paper proposed a promising method for removal of NOxand SO2from simulated ship emissions by wet scrubbing using electrolyzed seawater. Several factors were investigated on removal efficiencies of NO and NOxin a semi-continuous bubble column reactor. Results showed that NOxremoval was enhanced with the increase of active chlorine concentration, NO inlet concentration, reaction temperature, and concentrations of coexisting gases (CO2and O2), but was inhibited with increasing gas flow rate. The pH of the electrolyzed seawater had a significant impact on the NOxremoval. Then, simultaneous removal of NOxand SO2in both single stage and double stage reactors were studied preliminarily. Maximum removal efficiencies of NOxand SO2from simulated ship emissions (NOx1000 ppm, O215%, CO25%, SO2751 ppm) were 92% and 100% respectively under optimum conditions. Final products (NO2−and NO3−) of the process effluent were analyzed by the ion chromatography, and reaction pathways were also discussed.
