The CO reaction tower 2, the fan 3, the electric heater 5, the intake pipe 4, and the exhaust pipe 6 are all integrated in the container 1. The intake pipe 4 and the exhaust pipe 6 are both vertically arranged. The upper end of the intake pipe 4 extends out from the top of the container 1 and is provided with an intake interface 7. The lower end of the intake pipe 4 is connected to the inlet of the CO reaction tower 2 through the electric heater 5. The outlet of the CO reaction tower 2 is connected to the inlet of the fan 3 through a connecting pipe 9. The outlet of the fan 3 is connected to the lower end of the exhaust pipe 6. The upper end of the exhaust pipe 6 extends out from the top of the container 1 and is provided with an exhaust interface 8. Among them, the intake interface 7 and the exhaust interface 8 are respectively connected to the pilot project air intake pipe and the return air pipe. The fan 3 can be selected as a high-temperature fan for drawing out the flue gas.
[0028] As Figure 1 and Figure 2 shown, a preferred solution in this embodiment is that the CO reaction tower 2 is a horizontal reaction tower. Using a horizontal reaction tower is convenient for integration in the container.
[0029] As Figure 2 shown, the fan 3 in this embodiment is located at the rear side of the CO reaction tower 2. This makes the overall structure of the container compact.
[0030] As Figure 2 shown, the connecting pipe 9 in this embodiment is of an arc-shaped structure. By using the arc-shaped connecting pipe 9, the CO reaction tower 2 is located in front of the fan 2, and the fan 3 is located at the rear side.
[0031] Specifically, as Figure 1 and Figure 2 shown, the CO reaction tower 2 in this embodiment is provided with a CO catalyst packing 10.
[0032] As Figure 1As shown, the inlet of the CO reaction tower 2 is arranged upward, and the outlet of the CO reaction tower 2 is arranged horizontally.

A first detection port is provided on the CO reaction tower 2, and a second detection port is provided on the exhaust pipe 6. The inlet CO analyzer 11 is connected to the first detection port through a detection pipeline, and the outlet CO analyzer 12 is connected to the second detection port through a detection pipeline. The inlet CO concentration and the outlet CO concentration of the CO reaction tower can be detected respectively, and the CO analyzer can also retrieve the historical curve of the detection data.

Further, the air outlet of the air conditioner 13 can be directly opposite to the inlet CO analyzer 11 and the outlet CO analyzer 12 to prevent the working temperature in the container, especially that of the inlet CO analyzer and the outlet CO analyzer, from being too high.
[0035] Specifically, both the inlet CO analyzer 11 and the outlet CO analyzer 12 can be arranged at the left rear side of the container 1, and the air conditioner 13 can be arranged at the left front side of the container 1. A switch door can also be provided on the side wall of the container to facilitate the entry and exit of personnel.
