Activated carbon absorption box

The utility model discloses an activated carbon absorption box, which comprises a box body, first guide frames and movable plates, the top of the box body is symmetrically provided with the first guide frames, the inner sides of the first guide frames are movably provided with the movable plates, the inner side of the box body is symmetrically provided with a plurality of second guide frames, and the second guide frames are movably provided with the movable plates. Mounting blocks are symmetrically mounted on the inner wall of one side of the box body, rotating rods are movably mounted on the inner sides of the mounting blocks in a penetrating mode, a baffle is mounted at one end of each rotating rod, and a knocking rod is mounted on one side of each baffle. Waste gas is firstly blown to the baffle, the baffle can prevent the waste gas from being directly blown to the activated carbon body, so that continuous damage of strong wind to the activated carbon body is reduced, meanwhile, the waste gas blows up the
