step three: the flue gas after the drying enters into rose box (12), carry out final filtration to the flue gas through elementary filter (21) and senior filter (23), ensure that the flue gas is cleaner, simultaneously activated carbon plate (25) are better adsorbs the peculiar smell in the flue gas, ensure that exhaust flue gas is environmental protection more, draw-in groove and elementary filter (21) simultaneously, senior filter (23) and activated carbon plate (25) sliding connection, conveniently change, guarantee filtration efficiency, better change through chamber door (13).
