The research status of the world diesel exhaust aftertreatment technology is summarized systemicallyo at the same time, the development status and problems about oxygenation catalysis converter and particulate filter are analyzed on the basis of mentioned informations, we bring up a diesel exhaust cleanse system, that adopts the technique course of catalysis conversion combining particulate collection and regeneration the system collects exhaust particulate by means of efficacious filtering material it can oxidize ho co and macromolecule solvable organic via catalyst and diesel oil additive enhanced temperature will partly oxidize collected particulate and ultimately achieve the aim of exhaust reduction, after processing system frame design and trial matching, it ' s detected that the system can surely cleanse gas exhaust and particulate in addition, gas - ejected combustion - supporting regeneration for diesel particulate filter is also researched, we have rudimentarily designed the software and hardware of the g as - ejected combustion - supporting system having processed a series of trials, we discover the rules of the system credibly working these rules demonstrate the right direction for researching gas - ejected combustion - supporting regeneration technology
本文系統地介紹了國內外柴油
機排氣后處理技術的研究現狀,分析了氧化催化轉化器和微粒
捕集器的發展現狀及存在的問題,以此為基礎,提出了一種柴油
機排氣凈化系統,該系統採用催化轉化與微粒
捕集及再生相結合的技術路線,通過過濾材料的有效過濾,將排氣中的微粒進行收集,藉助于催化劑和柴油添加劑使排氣中hc 、 co及高分子可溶性有
機物氧化,產生的高溫使得收集到的微粒部分氧化,從而達到降低排放的效果。通過系統結構設計和試驗匹配,實現了對氣體排放物和微粒的凈化。同時,論文中還進行了柴油
機微粒
捕集器噴氣助燃再生的研究,初步設計了噴氣助燃系統,進行了控制系統軟、硬體的開發,通過正交試驗,摸索出了噴氣助燃系統可靠工作的一般規律,為噴氣助燃再生技術的開發提供了方向。
