Embodiment Construction

[0030] Attached below picture , to further illustrate the online near-infrared spectrometer provided by the present invention.

[0031] in the attached picture Among them, 1 represents the light source, 2 and 16 represent the lens group, 3, 5, 7, 11 and 13 represent the fiber coupler, 4 and 14 represent the fiber, 6 and 12 represent the fiber switch, 8 represent the fiber sample detector, and 9 represent blank Reference cell, 10 is a standard filter, 17 is a slit, 18 is a plane mirror, 19 is a grating, 20 is a flat-field orthogonal optical group, and 21 is a linear array coupling device detector.

[0032] The online near-infrared spectrometer provided by the present invention has a light transmission process as follows: the light emitted by the light source (1) becomes parallel light after being collimated and filtered by the lens group (2), and the light is guided into the optical fiber (4) through the optical fiber coupler (3). ), through the fiber optic coupler (5), fiber...

Abstract

An on-line near infrared spectrograph is composed of light source, lens set, optical coupler, optical fibre, optical switch, optical sampling meter, blank reference pool, standard filter, slit, plane mirror, grating, optical set in orthogonality on flatfield and detector for charge-coupled device of linear array.

Description

technical field [0001] The invention relates to an on-line instrument, and more specifically to an on-line near-infrared spectrometer. Background technique [0002] Traditional laboratory analysis technology takes several hours or more to measure a data, and the data feedback speed is very slow, which is not suitable for timely and precise control of the device, and cannot perform quality card edge operation. The online instrument can quickly provide parameters to the control system, and the control system can optimize and accurately control the device in time according to these parameters. Therefore, it can reduce the severity and energy consumption of the device, and save high value-added components such as gasoline blending components. , It plays an important role in ensuring the smooth operation of the device under high production load, improving the degree of automation and reducing labor costs. [0003] Most of the traditional on-line analyzers are improved similar la...
