Description
Technical field
The utility model is related to a kind of detection means, more particularly to a kind of particle concentration device for fast detecting.
Background technology
Extraction-type particle monitoring instrument is that heated, the steam in flue gas is evaporated after the saturation wet flue gas of dust-laden are extracted out
Enter measurement chamber afterwards, popped one's head in laser forward scattering and measured, so as to obtain granular material discharged concentration value.
Present extraction-type particle monitoring instrument uses optical means mostly, because particle diameter, the color of particulate matter are to optics letter
Number have an impact, so the concentration value of particle monitoring instrument can not be directly equivalent to mass concentration.And discharge of pollutant sources scene particle
Thing concentration of emission moment raises, and suspects it is instrument problem mostly, and it is that instrument principle causes particle to be now difficult promptly and accurately to judge
Thing concentration of emission is too high or actual condition concentration of emission is too high.
But according to existing granular material discharged regulation, the method for optical measurement particle concentration, it is impossible to accurate measurement
The mass concentration of grain thing, it is necessary to use hand sample, the mode that filter membrane is weighed is compared, so as to correct optical principle measurement
The output of particulate matter analyzer, makes its output concentration be mass concentration.
Because hand sample is more numerous and diverse, hand sample equipment is individual very big, mobile inconvenient.Onsite application hand sample
Method generally require 3-4 person cooperative work and could complete, and complete sampling and need the time mostly.
But, when raising discharge of pollutant sources scene granular material discharged concentration moment, it is difficult to it is instrument promptly and accurately to judge
Principle causes granular material discharged excessive concentration, or caused by actual condition concentration of emission is too high.
