The air inlet pipe 2 extends into the absorption tank 8, and the tail end of the air inlet pipe is connected with a microporous aerator 7 so as to reduce the size of bubbles and strengthen the absorption and removal of carbon dioxide. The tail end of the air inlet pipe 2 can be connected with an air pump device for blowing air into the absorption tank 8 to remove CO2. In the invention, the microporous aerator 7 can adopt a hollow glass tube with a plurality of micropores with the aperture of 1-1.5 mm on the tube wall. The gas outlet pipe 5 is sequentially connected with CO2The detection device 3, the safety device 4 and the first one-way exhaust valve 11. One end of the air outlet pipe 5 is communicated with the headspace of the absorption tank 8 to ensure that the headspace does not extend below the liquid level, and the other end is an air outlet. The height of the microporous aerator 7 in the absorption tank 8 is lower than the air inlet at one end of the air outlet pipe 5 by a certain distance.
