优选地，用于新能源混合动力汽车的新型尾气净化装置中，所述吸附层包括活性碳芯和滤网，且滤网位于吸附层中贴近净化腔的一侧。
优选地，用于新能源混合动力汽车的新型尾气净化装置中，所述净化腔和吸收腔通过卡扣扣接。
优选地，用于新能源混合动力汽车的新型尾气净化装置中，所述净化腔和吸收腔的外侧管壁涂有耐高温漆层。
优选地，用于新能源混合动力汽车的新型尾气净化装置中，所述所述溶解室的顶部设有进水口，所述溶解室的底部设有出水口。
优选地，用于新能源混合动力汽车的新型尾气净化装置中，所述滤音板上设有蜂窝状通气孔。
本发明的有益效果是：
本发明结构设计合理，一方面通过吸附层吸附尾气中的固体悬浮微粒，通过净化腔除去一氧化碳、碳氢化合物和氮氧化合物，通过溶解室吸收硫氧化合物，通过多级净化作用，可以增加装置对尾气中有害气体的净化种类，提高净化效果，由于净化腔和吸收腔之间通过卡扣进行连接，使得净化腔和吸收腔便于进行拆卸，进而便于清洗和保养，另一方面通过消音室将尾气经过多次反射碰撞，减少声波中的能量，进而达到降噪效果。
当然，实施本发明的任一产品并不一定需要同时达到以上所述的所有优点。
