Description

technical field [0001] The invention relates to a gas quantitative analysis technology, in particular to a quantitative analysis method and analysis system for gas products and gas fire extinguishing agents in a fire scene. Background technique [0002] Fire is one of the most frequent and destructive hazards in various disasters. The gas products produced by fire are very toxic and are the main factor threatening the safety of personnel. In fire safety and related application fields, effective measurement of various fire gas products is a necessary analysis method. [0003] The gas products of the fire scene are often complex in composition and have large range changes. For example, wood fires generally only produce carbon monoxide and carbon dioxide, while oil fires can produce sulfur dioxide and nitrogen dioxide, and cable fires can also produce hydrogen chloride and other substances. Depending on the scale of the fire, the gas products Concentration changes are distribu...

Problems solved by technology

[0005] However, there is currently no measuring instrument that can perform quantitative analysis of gas fire extinguishing agents. At the same time, general gas quantitative measurement devices can only achieve the measurement of a small number of common gases at a single sampling point, which cannot meet the requirements for the dispersion distribution of gas fire extinguishing agents. Quantitative measurement applications require
