<p>A motor exhaust gas purification method and its system, both ends of activated carbon (AC) paper are separately wound around passive scroll (42) for the AC paper and active scroll (43) for the AC paper which are arranged in a cabinet (10a,10b),and the middle part between the ends is wound around the reel (20) arranged in the exhaust gas passage of a motor muffle pipe(100). When the AC paper is saturated with harmful substance, the active scroll(43) is rotated, the used AC paper on the reel (20) is then wrapped to the active scroll(43), at the same time, the passive scroll (42) rotates with the rotating of the used AC paper, and the new AC paper is released and wrapped on the reel(20) over again until a circle of new AC paper is wrapped. The passive scroll (42) and the active scroll (43) are replaced when the new AC paper on the passive scroll (42) is released entirely. The invention uses the replaceable AC paper for absorbing harmful substance in the exhaust gas without secondary pollution to the environment.</p> |
