Description

Technical Field

[0001] The utility model relates to the technical field of power plant smoke detection, in particular to an analyzer for measuring smoke components in power plants. Background Art

[0002] Since my country started to work on air pollution source emissions, relevant departments have been continuously issuing relevant technical guidelines and emission standard requirements. Domestic work on regulating air pollution source emissions has developed rapidly. Against this background, it has also promoted the technological innovation of domestic flue gas analyzers. At present, ultraviolet and infrared principles of flue gas online monitoring systems are used in power plants; enterprises choose appropriate monitoring systems according to their own needs; if the monitoring speed requirements are high, and it is hoped that the detection of multiple pollutants can be completed in a short time, the use of chemical reagents can be minimized during the monitoring process, the risk of secondary pollution can be reduced, and high stability can be maintained during long-term use, then an ultraviolet principle flue gas online monitoring system can be selected.

[0003] Existing analyzers for measuring flue gas composition in power plants usually choose to use infrared flue gas analyzers to detect flue gas in power plants. However, infrared flue gas analyzers are prone to gas cross-interference. For example, if multiple gases such as SO2 and NOX appear in the monitoring environment at the same time, they are likely to cancel each other out, resulting in inaccurate measurement results. The ultraviolet analyzer uses ultraviolet differential technology to directly measure the absorption spectrum of the measured gas. Compared with traditional infrared flue gas analyzers, the ultraviolet analyzer solves the problem of gas cross-interference and has more accurate detection accuracy. Utility Model Content
