When the upper limit is exceeded, the harmful components in the gas cannot be completely treated and will be directly discharged into the atmosphere. Therefore, the staff needs to perform water replacement operations in a timely manner, which is time-consuming and labor-intensive. Utility Model Content

[0029] The driving assembly drives the connecting shaft 4, and the driving assembly includes but is not limited to the motor 6. The driving assembly drives the partition 5 to rotate to push the liquid adsorbent in the original collecting bin 101 into the original discharge bin 102, and at the same time pushes the liquid adsorbent in the original feeding bin 103 into the original collecting bin 101.

[0030] The exhaust pipe 7 is connected to the bottom cover 3 and communicated with the interior of the collecting bin 101, and the pipe opening of the exhaust pipe 7 is located below the liquid level of the liquid adsorbent in the collecting bin 101. The bottom cover 3 is provided with an air inlet 301 communicated with the interior of the collecting bin 101, the exhaust pipe 7 is covered and arranged outside the air inlet 301, and a check valve 71 is arranged inside the exhaust pipe 7.

[0031] The gas storage tank 10 is connected to the top cover 2 and communicated with the inside of the collection bin 101, and the air inlet end of the gas storage tank 10 is located above the liquid level of the liquid adsorbent in the collection bin 101. The output end of the gas storage tank 10 is connected to the exhaust pipe 11, and a valve A111 is arranged in the exhaust pipe 11, and a gas detection probe 16 is arranged in the gas storage tank 10. An air outlet 201 is arranged on the top cover 2, and the air outlet 201 is communicated with the collection bin 101, and the air inlet end of the gas storage tank 10 is covered and arranged outside the air outlet 201. A piston plate 13 is arranged in sliding connection with the inner wall of the gas storage tank 10, and a spring 15 for pressing the piston plate 13 downward is arranged in the gas storage tank 10, and an air guide pipe 14 is arranged on the piston plate 13, and the air guide pipe 14 is communicated with the collection bin 101 and the exhaust pipe 11, and the gas detection probe 16 is located below the piston plate 13.

When the gas detection probe 16 detects that the signal is normal, the valve A111 is opened and the valve B121 is closed. The equipment resumes normal operation. At this time, the staff only needs to fill the feeding bin 103 with liquid adsorbent.
