The invention relates to the field of flue gas filtration, and provides an optical measuring probe system for high-humidity low-concentration flue gas pollutants. The optical measuring probe system is used for solving the problem that in the prior art, an error is easy to occur in a flue gas detection process, and a probe is not easy to clean. The optical measuring probe system is characterized in that a probe is connected with a probe filtering structure, and a reflowing device is connected with the probe; under the action of negative pressure generated by the reflowing device, gas in a flue flows into the probe, then the probe carries out measurement on the gas; the probe filtering structure is sleeved outside an air vent of the probe and used for filtering impurities in the gas; a flexible filter material of the probe filtering structure covers the air vent of the probe; and the flexible filter material is composed of a layer of long fiber woven fabrics and a layer of polytetrafluoroethylene film with micropores. Through a dust-proof cover and the flexible filter material in the embodiment of the invention, a purpose of enhancing a filtering effect can be achieved, and lenses and filtering structures in the probe can be cleaned.
Description
[0001] This application claims the priority of the Chinese patent application with the application number 201010290012.4 submitted to the China Patent Office on September 25, 2010, and the title of the invention is "An Optical Measurement Probe System for High Humidity and Low Concentration Flue Gas Pollutants", the entire content of which is approved References are incorporated in this application. technical field [0002] The invention relates to the field of smoke detection, in particular to an optical measuring probe system for high-humidity and low-concentration smoke pollutants. Background technique [0003] Due to the increasing environmental pollution and human attention to environmental issues, the continuous monitoring technology of fixed pollution sources has been developed, especially the SO in flue gas pollutants discharged from boilers. 2 and NO X Gas monitoring technology is developed. [0004] The extraction continuous emission monitoring system for flue ga...
