低温等离子体技术净化船舶柴油机尾气的化学反应动力学模拟

摘要

针对目前尚没有一种净化方法能同时去除船舶柴油机尾气中NOx ，SO2和炭粒的现状，提出将低温等离子体技术应用于船舶柴油机尾气净化中。利用MATLAB，根据化学反应动力学原理建立关于低温等离子体技术净化NOx和SO2的微分方程组，对船舶尾气中NOx和SO2的净化效果进行模拟。在此基础上，进一步研究尾气中的SO2含量和O2含量对尾气处理效果的影响。理论研究结果说明此方法是可行的。利用低温等离子体技术净化船舶柴油机尾气具有较好的发展前景。%Considering that there exist no cleaning methods that can remove NOx ,SO2 and carbon parti-cles together from marine diesel engine flue gas,it is proposed that the low temperature plasma technology is put forward for cleaning marine diesel engine flue gas. The differential equations of removing NOx and SO2 by the technology are established by MATLAB according to the chemical reaction kinetics. The effects of removing NOx and SO2 from marine diesel engine flue gas are simulated. On this basis,the in-fluences of SO2 and O2 contents in flue gas on treatment effect are further studied. The theoretical re-search results show that the method is feasible. It has better development prospect to use the technology to clean marine diesel engine flue gas.
