Industry on-line near-infrared spectrum detection device

Abstract

The invention discloses an industry online near infrared spectrometry device, comprising a near infrared light source, a near infrared spectrometer, two three-bifurcation fibres, two reference measurement sampling pipes and an online measurement sampling pipe; the walls of sampling pipes are uniformly provided with a pair of corresponding optical path holes; the near infrared light source is respectively connected with the incidence optical path holes of three sampling pipes by three-bifurcation ends of the first three-bifurcation fibre; the exit optical path holes of the three sampling pipes are respectively provided with a sunshade mechanism; each sunshade mechanism is respectively connected with the three-bifurcation ends of the second three-bifurcation fibre; the other end of the second three-bifurcation fibre is connected with the near infrared spectrometer. The device of the invention is used for measuring the reference matters and measuring the spectrogram of samples, carrying out the operation processing of the obtained spectrogram, which can eliminate the interferences of the changes of the optical intensity and spectral properties and of the sensitiveness change of the spectrometer detector to the measurement results, realize the failure diagnosis of the optical path system, and can correct the wavelength of the spectrogram obtained by the spectrometer. The device of the invention has the advantages of reliable measurement results and high precision.

Description

Technical field [0001] The invention relates to a near-infrared spectrum detection device, especially an industrial online near-infrared spectrum detection device. Background technique [0002] With the development of chemometrics, near-infrared spectroscopy analysis technology has emerged in the late 1980s and has become an independent analysis technology. With its characteristics of fast analysis speed, no damage to samples, no reagents, and no environmental pollution, Its application areas are expanding day by day. [0003] In order to finally obtain qualified products, modern large-scale process industrial production requires effective and timely monitoring of the production process, and offline laboratory analysis data often lags behind the production process. The process parameters that need to be adjusted are often not implemented in time, and even lead to intermediate products. Or rework or scrapping of the final product. Near-infrared spectroscopy analysis technology can...
