The movable plate 10 is movably connected. After the movable plate 10 moves, it can drive the meshing teeth 15 connected to its inner wall to move, and the meshing teeth 15 drive the gear 13 to transmit, thereby completing the driving work of the stirring rod 12, so that the stirring rod 12 can stir the activated carbon area, and the position of the activated carbon changes, so it can adsorb sulfur dioxide through different faces. The top of the transparent plate 7 is slidably connected with the movable plate 10, and the inner side of the movable plate 10 is provided with a second vent hole 14, the inner diameter of the second vent hole 14 is equal to the inner diameter of the first vent hole 8, and after the first vent hole 8 is connected to the second vent hole 14, it is convenient to output the gas after adsorbing sulfur dioxide, and the inner side of the movable plate 10 is provided with a meshing tooth 15;

[0022] An output pipe 5 is connected to the top of the shell 3, and a bolt 4 is threadedly connected to the middle part of one side of the outer wall of the shell 3. The bolt 4 and the movable plate 10 are movably connected. The bolt 4 is manually rotated to extend into the shell 3, thereby pushing the movable plate 10 movably connected thereto to move, completing the misalignment work between the second air hole 14 and the first air hole 8, so that the sulfur dioxide gas continues to contact and adsorb the activated carbon in the first activated carbon area 6. The shell 3 and the ventilation pipe 2 are threadedly connected. When the components inside the shell 3 need to be replaced, it is convenient to disassemble and assemble the shell 3.

[0023] Working principle: When in use, the staff first pours sulfuric acid into the storage tank body 1. During this period, sulfur dioxide escapes through the ventilation pipe 2, so it enters the first activated carbon area 6 in the shell 3, so that the activated carbon adsorbs sulfur dioxide. Subsequently, the gas continues to escape and passes through the first ventilation hole 8. The gas after one adsorption is tested by the test paper 9. If the color change of the test paper 9 is large, the bolt 4 is manually turned to make it extend into the shell 3, thereby pushing the movable plate 10 that is movably connected with it to move, and the process is completed. The misalignment between the second vent hole 14 and the first vent hole 8 completes the work of covering the first vent hole 8. During this period, after the movable plate 10 moves, it can drive the meshing teeth 15 connected to its inner wall to move, and the meshing teeth 15 drives the gear 13 to transmit, thereby completing the driving work of the stirring rod 12, so that the stirring rod 12 can stir the activated carbon area, and the position of the activated carbon is changed, so it can adsorb sulfur dioxide through different faces. Finally, under the adsorption effect of the second activated carbon area 11, all the escaped sulfur dioxide is adsorbed.
