Description

technical field [0001] The proposal relates to the technical field of on-line and on-site monitoring of industrial hazardous gas leakage, and in particular to an adaptive reflective infrared laser industrial hazardous gas leakage monitoring device. Background technique [0002] At present, with the rapid development of industry, it is inevitable to produce flammable, explosive and poisonous dangerous gases, such as methane and carbon monoxide (CO), in the production process of chemical industry, mining industry and oil and gas mining industry. Once the dangerous gas leaks, it will cause explosion and poisoning, which will lead to major safety accidents and cause huge losses of personnel and property. [0003] Tunable semiconductor laser absorption spectroscopy technology (TDLAS) based on an open optical path is an effective means widely used in industrial dangerous gas leakage monitoring (such as oil and gas exploration and chemical industry, etc.). , using the absorption e...
