Parabolic-mirror-based open type optical long-range pool

Abstract

The invention relates to a parabolic-mirror-based open type optical long-range pool, and belongs to the field of a gas phase monitoring technology. The parabolic-mirror-based open type optical long-range pool is characterized by comprising four planar parabolic mirrors, an open air gas chamber, optical fiber couplers, horizontal guiderails and a spiral propeller; the four planar parabolic mirrors are distributed in the open gas chamber diagonally and perpendicular to an upper disc and a bottom disc of the open gas chamber; the four horizontal guiderails are diagonally arranged on the upper disc of the open gas chamber, the four horizontal guiderails are correspondingly arranged on the bottom disc of the open gas chamber, the parabolic mirrors are arranged on the horizontal guiderails; incidence holes and emergence holes are formed in the planar parabolic mirrors and provided with the optical fiber couplers; the spiral propeller is connected with and pushes the planar parabolic mirrors to do linear movement. The parabolic-mirror-based open type optical long-range pool has the advantages of being simple in structure, easy to regulate and realize, capable of automatically setting an effective optical path, applicable to automatic online monitoring of low-concentration gas areas of a production site, and the like, and the environment safety of a production site can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of gas phase monitoring, in particular to an open optical long-range cell based on a parabolic mirror. Background technique [0002] At present, with the rapid development of the petroleum industry, with more and more gas leakage incidents, explosion accidents and air pollution occur frequently, which greatly threatens the living environment and property safety. Therefore, online monitoring of flammable gases and toxic and harmful gases is particularly important. Some confined spaces, such as reaction tanks, oil tanks, lack of good ventilation workshops, underground pipes, underground drains, cabins, etc. All are important places where harmful gas detection is required. Petrochemical enterprises are common places where dangerous gases exist. Flammable, explosive, toxic and harmful gas leaks may occur from raw material collection, production process to product storage and transportation. Therefore, online m...

Problems solved by technology

However, in the existing absorption cells, the absorption cell with simple manufacturing process and stable system can achieve a small effective optical path; the absorption cell with a large optical path has complicated manufacturing process and poor system stability, which is not easy to achieve. Conducive to on-site low concentration measurement and other technical issues
