2.5monitor quality is uneven, cannot PM in accurate evaluation surrounding air
2.5content.For ensureing PM
2.5accurately and reliably, the U.S., Japan, European Union etc. have carried out detection method standardization and the research of metering traceability to Monitoring Data.The external single channel PM set up
2.5monitor calibrating installation, at calibration PM
2.5need during monitor to prepare multiple single size gasoloid, whole pipeline must be cleaned before different size gasoloid is passed into calibrating installation, process is loaded down with trivial details, calibration efficiency is low, and the longer rate that exists purging dead angle that causes of pipeline increases, cause having different size aerosol particle to remain, affect calibration accuracy.
Summary of the invention
In order to solve the problem, the invention provides a kind of hyperchannel PM
2.5monitor calibrating installation, this device overall construction design is reasonable, and avoid the problem that existing calibration system needs to repeat to purge whole pipeline, precision and efficiency of detecting is high, and cost is lower, simple to operate, is easy to promote the use of.
In order to achieve the above object, technical scheme of the present invention is:
A kind of hyperchannel PM2.5 monitor calibrating installation, it is characterized in that: comprise aerosol generator 1, first blending bin 103, second blending bin 203, the 3rd blending bin 303, the 4th blending bin 403, the 5th blending bin 503, the 6th blending bin 603, the 7th blending bin 703, the 8th blending bin 803, PM2.5 monitor 5, preposition particle diameter spectrometer 7, PM2.5 cutter 8, rearmounted particle diameter spectrometer 9 and clarifier I 6, clarifier II 10, connected with thread forms by pipeline between its each several part; Aerosol generator 1 is connected with the first blending bin 103, second blending bin 203 in parallel successively, the 3rd blending bin 303, the 4th blending bin 403, the 5th blending bin 503, the 6th blending bin 603, the 7th blending bin 703, the 8th blending bin 803 simultaneously; First blending bin 103, second blending bin 203 in parallel successively, the 3rd blending bin 303, the 4th blending bin 403, the 5th blending bin 503, the 6th blending bin 603, the 7th blending bin 703, the 8th blending bin 803 downstream are connected with preposition particle diameter spectrometer 7 with PM2.5 monitor 5 again simultaneously; PM2.5 monitor 5 downstream pipe connects clarifier I 6; Preposition particle diameter spectrometer 7 downstream pipe connects PM2.5 cutter 8, rearmounted particle diameter spectrometer 9 and clarifier II 10 successively.
Owing to have employed described technical scheme, the present invention has following superiority:
1, eight kinds of single size gasoloids enter detecting instrument respectively by respective corresponding pipeline, do not need to purge whole pipeline before passing into different size gasoloid, only need to purge public part, improve calibration efficiency, reduce error.
2, system of the present invention is adopted accurately can to measure PM
2.5aerocolloidal concentration, meets calibration PM
2.5the requirement of monitor, simple to operate, can the continuous working long period, be easy to apply in gauge check industry.
