摘要
论及强电离放电非平衡等离子体技术应用于净化内燃机尾气中NOX 的研究。分析了强电离放电产生等离子体净化内燃机尾气原理 ,主要讨论了折合电场强度对NOX 脱除率的影响。当折合电场强度达到 6 2 4× 10 4V/cm时 ,NO的脱除率达到 91% ;当折合电场强度达到 6 76× 10 4V/cm时 ,NOX 的总体脱除率达到 4 9
The removal of NO X in the exhaust gas of internal-combustion engine by the technology of strong ionization discharge nonequilibrium plasma is discussed and the principle how the strong ionization discharge reactor works is also analyzed.The relation between NO X removal rate and reduced electric field is discussed in details.As a experimental result,the NO removal rate comes up to 91 percent while the reduced electric field has been enhanced to 6.24×10 4 V/cm ,and the highest removal rate of total NO X is 49.3 percent which attained at 6.76×10 4 V/cm.
