[0051] Working principle:

[0052] S1: The exhaust motor 511 drives the rotating base 521 and the exhaust impeller 52 to rotate, and the gas is extracted into the interior through the exhaust pipe 53. During the extraction process, the flue gas first passes through the particle filter 561, which filters out large particles of impurities in the flue gas. When the flue gas passes through the adsorption layer 564, the fibers in the adsorption layer 564 adsorb the moisture in the flue gas. The adsorbed flue gas is then extracted into the exhaust housing 51 through the pipe.

[0053] S2: The heating ring 551 heats the heat exchange inner tank 5211, and the heat is transferred to the exhaust impeller 52. The exhaust impeller 52 then heats the flue gas during the extraction process, evaporating the water vapor in the flue gas. The water vapor is then discharged through the exhaust pipe 54 to the gas injection tank 442 in the built-in gas seat 44.

[0054] S3: The rotating motor 41 drives the gas storage annular seat 42 to rotate through gear meshing, so that the air inlet 423 on the inner end face of a single gas storage space is rotated and aligned with the exhaust hole 441 provided on the outer end face of the built-in gas seat 44. The gas in the built-in gas seat 44 is discharged into the gas storage space for storage. When the air inlet 423 rotates and is misaligned with the exhaust hole 441, the air inlet 423 and the exhaust hole 441 are respectively blocked. When the gas is pumped out again, the air inlet 423 on the inner end face of the next gas storage space is rotated and aligned, so that multiple gases are stored separately.

[0055] When the air is exhausted, the air inlet 423 at the inner end of the air storage space is rotated to align with the exhaust hole 441, and the exhaust motor 511 is driven in the reverse direction to exhaust the air in the delivery pipe 54 and exhaust the air in the exhaust pipe 53. At this time, the solenoid valve on the air distribution pipe at the outer end of the air storage space aligned with the exhaust hole 441 is opened, and communicates with the annular air storage tank 421 in the vent seat 425. When the exhaust motor 511 exhausts air in the reverse direction, the air filtered by the air purifier 45 is extracted and replaced with the gas when passing through the air injection tank 442, the exhaust shell 51 and the exhaust pipe 53, so as to prevent the gas extracted last time from being stored inside and to avoid mixing when multiple gases are extracted. When the exchanged gas passes through the exhaust shell 51, it exchanges heat with the exhaust impeller 52. When the heated gas is discharged through the adsorption layer 564, the adsorption layer 564 is heated to evaporate the water vapor adsorbed inside, so that the adsorption layer 564 can be reused.

[0056] S5: When the gas in the gas storage space needs to be detected, the solenoid valve on the exhaust bend 422 below the gas storage space to be detected is opened to transport the gas in the gas storage space to the detection chamber 36. The divergent lens converts the scattered light emitted by the light source into parallel light, which then enters the gas chamber. The focusing lens converts the parallel light in the detection chamber 36 into focused light and then transmits it to the optical fiber 32. The optical fiber 32 transmits the signal to the spectrometer 34. The spectrometer 34 mainly collects spectral signals and converts them into electrical signals. It is also responsible for transmitting the optical information to the processor 31 in real time. The processor 31 performs the optical signal processing on the flue gas. Perform analysis to achieve flue gas ultraviolet analysis. When the flue gas analysis is completed, the exhaust pipe at the bottom of the detection chamber 36 is connected to the fan to extract the gas in the detection chamber 36. At this time, the solenoid valve on the gas distribution pipe in the gas storage space interconnected with the detection chamber 36 is opened, and the air inlet 423 and the exhaust hole 441 on the gas storage space are misaligned. When the fan extracts the gas in the detection chamber 36, the gas filtered by the air purifier 45 is extracted, and the interior is ventilated when passing through the gas storage space and the detection chamber 36 to prevent the internal gas from mixing during the secondary detection and affecting the detection result.
