Description
[technical field]
The present invention relates to a kind of calibration method and calibrating installation of flue gas discharge continuous monitoring system.
[background technology]
" flue gas discharge continuous monitoring system " (being called for short CEMS) is a kind of through sampling, analysis mode or direct metering system; Measure the equipment of pollutant levels such as sulfur dioxide in flue gas, oxides of nitrogen and oxygen level, used widely in industries such as power plant, metallurgy, mining and metallurgy, petrochemical industry, environmental monitorings.For promoting the reduction of discharging work of the total amount of pollutant, protect atmospheric environment, each relevant enterprise is using online boiler smoke discharging continuous monitor system, and this system replaces the monitoring mode of artificial continuous sampling, has improved the promptness and the accuracy of flue gas data monitoring.
But because the complicacy of monitoring " object environment "; High dirt, high humidity, high pollution property, the erosion of the easy contaminated thing of flue gas discharge continuous monitoring system, infringement make the measurement result data produce deviation; Shorten the serviceable life of monitoring system; Influence accuracy, the validity of online monitoring data, this just causes there is not comparability between testing result, and supervision department can't directly adopt Monitoring Data to carry out the evaluation of pollution source emission level.Therefore, need comprehensive, the objectively metering evaluation of carrying out flue gas discharge continuous monitoring system badly,, but do not have those skilled in the relevant art that this is studied with accuracy, the validity of guarantee online monitoring data.
Therefore, so far, China does not have perfect flue gas discharge continuous monitoring system measurement and examination method, and corresponding standard verification apparatus, and the measurement verification lack of scientific of existing flue gas discharge continuous monitoring system, otherwise effective technique are supported.
