| Influencing factor | Specific reason | Inspection method | Solutions and optimizations |
| 1 | Low exhaust gas concentration | The exhaust gas is stable and its concentration is low | The concentration of imported exhaust gas is continuously measured by mobile FID | If possible, increase the concentration multiple and reduce the post-concentration air volume |
| 2 | The exhaust gas is unstable, and the concentration is low for more time | The concentration of imported exhaust gas is continuously measured by mobile FID | Optimized operating parameters are adopted according to actual working conditions and automatically adjusted according to exhaust gas concentration |
| 3 | Zeolite runner performance degradation or damage | Zeoliter runner to service life | Check the appearance of zeolite runner and the inlet and outlet pressure difference, and test the treatment efficiency of zeolite runner | Replace the new runner or part of the module |
| 4 | Dust clogging due to front-end filtration failure | Detection of zeolite runner processing efficiency;Check the filter box and zeolite runner appearance and pressure difference | Replace and improve front filter,set alarm; |
| 5 | Blockage caused by substances with a high boiling point | Detection of zeolite runner processing efficiency;Check the appearance of zeoliter runner and the inlet and outlet pressure diffference, analyze the exhaust gas composition. | The exhaust gas with high boiling point is separated to avoid entering the runner;Or pre-treatment to reduce the content of high-boiling substances. |
| 6 | The corrosive nature of exhaust gas leads to the damage of zeolite properties | Detection of zeolite runner processing efficiency;Check the appearance of zeoliter runner and the inlet and outlet pressure diffference, analyze the exhaust gas composition. | The corrosive exhaust gas is separated to avoid entering the runner or to predispose the group to remove the corrosive exhaust gas components alliance |
| 7 | The concentration multiple design is low | Improper design and selection | Check the design date and accounting, and actual measurement if possible, according to the actual operating parameters more analysis. | If possible, according to the actual operating and change the wheel and other parts |
| 8 | CO system design is not reasonable | The designed CO heat transfer system is not properly designed | Check design date and accounting, and actual measurement analysis | If possible, adjust the structure or replace |
| 9 | The heat exchanger used has a low thermal efficiency | Check design date and accounting, and actual measurement analysis | Adjust or replace if possible |
| 10 | Catalyst degradation or failure | Catalyst to working life | The concentration of exhaust gas at the inlet and outlet of CO system was continuously detected by mobile FID to measure and analyze the system | Catelyst replacement |
| 11 | Catalyst poisoning | Use mobile FID to pretreat the exhaust gas at the inlet and outlet of the CO system if it is possible to carry out continuous concentration detection of the catalyst ocntaining poisoning.Or content analysis;Open the CO furnace to check the catalyst | Resulting in the isolation of the toxic gas containing the catalyst |
| 12 | The heat transfer efficiency of the heat exchanger decrease | There is adhesion on the heat exchanger surface | Check the cold and hot end paramters of the heat exchanger compare and analyze with the design parameters; Check the heat exchanger if possible | Clean the surface of the heat exchanger with the accessory S/Ishiko listening blood |
