[0041] Step 2: The heated flue gas enters the first oxygen monitor 6, the first sulfur dioxide monitor 601, the first nitrogen oxide monitor 602, and the first carbon monoxide monitor 603 to monitor the component content in the flue gas, and passes through the second pressure and temperature monitor 7 to monitor the pressure and temperature of the flue gas again.

[0044] Among them, the flue gas inlet 1 of step one is carefully designed to ensure that the on-site flue gas can be steadily and smoothly introduced into the device, reducing the impact of airflow fluctuations on subsequent detection and response.

[0045] Among them, the variable frequency induced draft fan 3 in step one flexibly adjusts the working frequency of the induced draft fan according to actual needs, thereby effectively controlling the flow rate and flow of the flue gas and ensuring the stability of the airflow during the entire monitoring process.

[0050] The specific usage and function of this embodiment are as follows:

Then, by adjusting the operation of the variable frequency induced draft fan 3, the flue gas flows through the flow measuring device 4, thereby realizing accurate detection and regulation of the flue gas flow rate to adjust to a suitable flue gas flow rate. Then, the flue gas passes through the electric heater 5 and is quickly heated to a specific temperature requirement. Only when this temperature condition is reached can the flue gas smoothly enter the three-layer carbon monoxide oxidation catalyst for reaction. Before the flue gas enters the carbon monoxide oxidation catalyst, each monitoring point will perform a comprehensive detection and analysis on it to obtain the initial parameters. After entering the carbon monoxide oxidation catalyst, the flue gas flows through the three layers of carbon monoxide oxidation catalyst. When passing through each layer of catalyst, the corresponding sampling points, temperature monitoring points and pressure monitoring points will play a role, and relevant data will be monitored and recorded in real time. After a period of reaction, the flue gas is again detected and analyzed by a series of monitoring points. Then, the flue gas is discharged from the flue gas outlet 15. Finally, by comparing the detection concentration of oxygen before and after the reactor and combining other monitoring data, the performance of the carbon monoxide oxidation catalyst is comprehensively and accurately evaluated.
