Description
Technical field
The utility model relates to on-line monitoring system of flue gas discharge field, particularly relates to extraction-type fume emission gas-monitoring pollutant measurement calibration system.
Background technology
Extraction-type on-line monitoring system of flue gas discharge adopts heated type directly to extract mode, workflow is that flue gas filters through sampling probe built-in filter, by electric tracing sampling line be delivered to flue gas pretreatment unit dewater, cooling, through flow regulation, enter gaseous contaminant analyser.Accurate for measurement data, generally all need to take Standard Gases NO
x, SO
2flue gas analyzer is demarcated.At present domestic existing calibration system is at the scene in implementation process, standard tracheae need to be received to outdoor sampling probe place, not only pipeline is oversize but also operate cumbersome, easily make sampling monitoring system generation gas leakage problem, cause side amount data inaccurate, secondly in the time of calibration flue gas analyzer and calibration sampling monitoring system, can not complete simply rapidly switching.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of extraction-type fume emission gas-monitoring pollutant measurement calibration system.
The technical scheme that the utility model adopts is: a kind of extraction-type fume emission gas-monitoring pollutant measurement calibration system, mainly comprise calibrating gas bottle, BULKHEAD UNION, flue gas analyzer, described calibrating gas bottle is connected by tracheae with BULKHEAD UNION, described BULKHEAD UNION is connected by tracheae with flowmeter, one, described flowmeter is connected by tracheae with system calibration valve, other end is connected by tracheae with manually-operated gate, described system calibration valve while and blowback stop valve, probe back-flushing valve, flow velocity back-flushing valve connects by tracheae, described manually-operated gate while and anticorrosion throttling valve, the outlet of dehumidifying filtering system connects by tracheae, described anticorrosion throttling valve is connected by tracheae with flue gas analyzer.
The beneficial effects of the utility model are: Standard Gases accesses monitoring system quickly and easily, and by switch valve not only adjustable analyser but also adjustable monitoring system.Calibration gas enters flue gas analysis instrument system after sampling probe and sampling pipeline again, carrys out control valve by gas-monitoring oxygen level, can ensure that the system of entering is calibrating gas entirely, and calibration result is more accurately objective.
