[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0027] See also Figures 1 to 4 In the utility model: a carbon dioxide emission monitor comprises a monitoring box 1, a gas supply pipe 2 is arranged above the monitoring box 1, an air intake pipe 3 and a return pipe 4 are connected to the bottom of the gas supply pipe 2, a filter cartridge 5 is connected to the bottom end of the air intake pipe 3, a filter plate 6 is fixedly connected to the inner wall of the filter cartridge 5, the bottom of the filter cartridge 5 is connected to the monitoring box 1, a mounting hole 7 is opened on the top of the monitoring box 1, a gas detector 8 is installed on the inner wall of the mounting hole 7, a piston plate 9 is slidably connected to the inner wall of the monitoring box 1, an electric push rod 10 fixedly connected to the bottom of the monitoring box 1 is inserted, and an electric control valve 11 is installed on both the air intake pipe 3 and the return pipe 4.

[0028] In the utility model, when in use, the discharged gas circulates inside the gas supply pipe 2. When it is necessary to monitor the discharged gas, the user opens the electric control valve 11 on the air inlet pipe 3. At this time, the gas inside the gas supply pipe 2 will enter the filter cartridge 5 through the air inlet pipe 3. The filter plate 6 inside the filter cartridge 5 will filter the dust in the gas. The filtered gas will then enter the monitoring box 1 from the filter cartridge 5. As the gas enters, the piston plate 9 will descend along the inner wall of the monitoring box 1 until the bottom of the piston plate 9 contacts the electric push rod 10. The monitoring box 1 will be filled with gas to achieve the purpose of collecting a certain amount of gas. At this time, the electric control valve 11 is closed, and the gas detector 8 is turned on to detect the gas inside the monitoring box 1. It can be known that the gas inside the two The proportion of carbon dioxide occupied by carbon dioxide is realized to achieve the purpose of monitoring the carbon dioxide content. After the monitoring is completed, the user starts the electric push rod 10 and opens the electric control valve 11 on the reflux pipe 4. The electric push rod 10 will push the piston plate 9 to move upward, and the piston plate 9 will squeeze out the gas inside the monitoring box 1. The gas will then pass through the filter plate 6 in the opposite direction and flow back to the gas supply pipe 2 through the reflux pipe 4. After the air inside the monitoring box 1 is exhausted, the next monitoring can be carried out. During the monitoring process, before the gas enters the monitoring box 1, there is no other gas inside the monitoring box 1, thereby effectively improving the effect of gas detection, and when the air flows back from the monitoring box 1, the air passes through the filter plate 6 in the opposite direction, which can achieve the purpose of recoil cleaning of the filter plate 6, which is beneficial to the next gas filtering.

[0031] See also Figure 3 , wherein: the top end of the electric push rod 10 is fixedly connected with a mounting plate 14 , and the top of the mounting plate 14 is installed with a control switch 15 .

[0032] In the utility model, after the gas inside the monitoring box 1 is filled, the bottom of the piston plate 9 will contact and trigger the control switch 15. After the control switch 15 is triggered, the electric control valve 11 on the air intake pipe 3 will be closed, thereby effectively controlling the air flow entering the monitoring box 1.

[0033] See also Figures 1 to 3 , wherein: two air outlet holes 16 are provided at the bottom of the monitoring box 1, and the inner walls of the two air outlet holes 16 are fixedly connected with filter screens 17.
