[0002] Airflow dryers are widely used in the tobacco industry. In the process of tobacco processing in the tobacco silk workshop, airflow dryers are located at the end of the leaf production section. The role they play in the silk-making process is to remove excess moisture from the tobacco, so that the tobacco reaches the filling value, suction taste and storage conditions that are suitable for the production process requirements. Specifically, the airflow dryer passes high-temperature process gas into the drying section, so that the tobacco is fully in contact with the process gas in a very short time to dry and dehumidify, so that the tobacco curls, expands and dries, and reaches the required moisture content. In the actual operation process, the airflow dryer has high requirements for the emission of its exhaust gas, and it needs to meet environmental protection standards before it can be discharged. At the same time, in consideration of the combustion efficiency of the airflow dryer, it is also necessary to detect the carbon monoxide content in the exhaust gas. When the carbon monoxide content is detected to rise, the combustion furnace of the airflow dryer needs to be cleaned and maintained accordingly.
