Intermittent tail gas detection structure and tail gas detection control system

The invention discloses an intermittent tail gas detection structure and a tail gas detection control system which is suitable for asphalt stirring equipment.The intermittent tail gas detection structure comprises a fixed cover and a protective cover capable of moving relative to the fixed cover, and a tail gas detection sensor is contained and wrapped by a space formed after the protective cover and the fixed cover are closed in a matched mode and exposed out when the protective cover is opened.The content of tail gas generated in the combustion process of a combustor is intermittently detected by the tail gas detection structure, the air-oil ratio of the combustor is regulated according to detection data, complete combustion of fuel is guaranteed, and therefore the environmental performance of the combustor is improved; by adopting the intermittent tail gas detection structure, abrasion of a device with the tail gas detection structure is reduced, the service life is prolonged, and the using cost is reduced
