船舶尾气中的氮氧化物（NOx）、硫氧化物（SO2）、颗粒物（PM）等污染物对人体健康、环境和气候条件有很大影响。将选择性催化还原技术与干式净化技术相结合，建立了WD 10 C195 -15船用四冲程高速柴油机SCR-DryEGCS系统试验台，对柴油机尾气中NOx、SO2和PM的净化效果进行了分析。SCR-DryEGCS系统分别去除了89.03%、99%和96%的NOx、SO2和PM。并与低硫油联合SCR法进行了对比，验证了SCR-DryEGCS法的可行性。结果表明，SCR-DryEGCS系统具有自身的优势，对NOx、SOx和PM的同时脱除效果良好。
Pollutants such as nitrogen oxides (NOx), sulfur oxides (SO2), and particulate matter (PM) in ship exhaust have a great impact on human health, environment and climate conditions. Combined selective catalytic reduction technology and dry exhaust gas cleaning technology, a test rig (SCR-DryEGCS system) for WD10C195-15 marine four-stroke high speed diesel engine was established to analyse the removal effect of NOx, SO2, and PM from exhaust gas. The SCR-DryEGCS system removed 89.03%, 99%, and 96% of NOx, SO2, and PM respectively. And also compared with low sulfur oil combined SCR method to verify the feasibility of the SCR-DryEGCS method. It shows that the SCR-DryEGCS system has its own advantages and has a good effect on the removal of NOx, SOx, and PM at the same time.
