[0017] This invention provides an exhaust gas filtration and conveying system, such as... Figures 1-7 As shown, the system includes a filter housing 1, a filter frame 2 inside the filter housing 1, an activated carbon filter layer 3 inside the filter frame 2, a storage tank 4 for storing reactants on the filter housing 1, a flow monitor 5 for monitoring the flow rate of exhaust gas on the filter housing 1, and an adjustment unit inside the filter housing 1 for adjusting the discharge rate of the storage tank 4.
