The piston 18 is fixedly connected to the bottom of the piston rod 15. The piston 18 is slidably connected to the inner wall of the sampling box 14. The sampling pipe 12 is fixedly connected to the bottom of the sampling box 14. The filtering structure is located on the top of the rectangular plate 2. The filtering structure includes a filtering box 3, a first filter plate 20, a second filter plate 21, a third filter plate 22 and a limiting plate 23.

[0024] Furthermore, the sampling device further includes a stop valve 11, a stop valve two 13, a glass plate 17 and a scale line 19. The stop valve 11 is arranged on the outer surface of the air outlet pipe 10. The stop valve two 13 is arranged on the outer surface of the sampling pipe 12. The glass plate 17 is fixedly connected to the sampling box 14. The piston 18 is slidably connected to the glass plate 17. The scale line 19 is arranged on the outer wall of the sampling box 14. An air outlet is provided at the top of the sampling box 14. When sampling, first open the stop valve 11, move the piston 18 upward through the circular handle 16, and the volume of the sample can be judged through the scale line 19. After the piston 18 moves to a suitable position, close the stop valve 11. At this time, the gas inside the sampling box 14 can be taken out by opening the stop valve two 13.

After being filtered by the filter plates, finally the fan 4 transports the filtered gas into the interior of the gas storage tank 1 to complete the recovery of the gas. The purity of the gas can be improved through the filtering structure, and the quality of the recovered gas can be increased.

[0027] Working principle: The gas enters the interior of the filter box 3 through the air inlet pipe 6. The gas first passes through the first filter plate 20 to filter out particulate matter in the gas, then passes through the second filter plate 21 made of activated carbon to adsorb and filter harmful chemical substances, and then passes through the third filter plate 22 to deeply filter the gas. Finally, the fan 4 transports the filtered gas into the interior of the gas storage tank 1 to complete the recovery of the gas. When sampling, first open the stop valve 11. Move the piston 18 upward through the circular handle 16. The volume of the sample can be judged through the scale line 19. After the piston 18 moves to a suitable position, close the stop valve 11.
