Technical field
The utility model relates to pollution sources detection technique field, in particular to a kind of variable optical path tester for smoke concentration.
Background technique
Traditional dust concentration METHOD FOR CONTINUOUS DETERMINATION instrument mostly uses greatly laser to threading method, and measuring principle is based on Lamber-Be11,
That is one beer's law of youth uncle: i.e. when a monochromic beam (such as laser) passes through flow media containing particulate matter, due to particulate matter
Absorption, scattering and reflex, light intensity can decay, and the attenuation degree of light intensity meets following equation:
In formula: 1.For incident intensity, I is output intensity, and C is the mass concentration of particulate matter in medium, and K is and particulate matter
The relevant calibration coefficient of physical characteristic, L are the practical light path that light passes through medium.Traditional analyzer is surveyed once installing
Amount light path is a fixed value.
In practical application, by measuring output intensity I, incident intensity I, the reality that calibration coefficient K and light beam pass through are introduced
Light path L can find out corresponding flue dust depth C by formula (1).Traditional dust gauge in use, cause incident intensity decay because
Element mainly have 2, one is in medium particulate matter absorption, scattering and reflection；The second is particulate matter is to optics in being used for a long time
The pollution of mirror surface.
The latter is the main reason for causing analyzer to drift about, and this drift can make with using the time to be constantly increasing
At the severe deviations of measurement result.
In order to improve this phenomenon, back blowing machine is mostly introduced in traditional dust measuring system, forces blowback and media contact
Optical mirror plane prevents particulate matter in the accumulation of optical mirror plane, and the introducing of blowback system only plays the process for delaying pollution, but
Pollution of the particulate matter to mirror surface can not fundamentally be solved.
For the monitoring for realizing system, current most common way is periodically to carry out manual cleaning to optical mirror plane, and existing
Most of analyzers be unable to complete on-line maintenance optical mirror plane, be both needed to remove analyzer, after maintenance and cleaning, again by
Luminous energy alignment and system debug virtually increase the deviation of system caused by installing again.For this purpose, it is proposed that one kind can
Darkening journey dust concentration analyzer.
