Embodiment Construction
[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0022] like figure 1 As shown, a carbonyl sulfide (COS) trace gas real-time online observation device includes an optical path measurement unit, a laser control and signal processing unit, a gas path and an air pressure control unit, wherein:
[0023] The optical path measurement unit includes an infrared laser 4, a collimator lens 5, reflectors 6a, 6b, a gas absorption cell 7, and a photoelectric detector 8, and the optical path measurement unit is installed on the base plate at a fixed position and angle. Wherein the collimating lens 5 is installed on the shell of the infrared laser 4, facing the light output surface of the infrared laser. The reflector 6a is facing the output direction of the collimated light, and is used to deflect the output infrared collimated light. The reflector 6b is placed at the horizontal position of 6a and arranged at a ce...
