Abstract

The invention discloses a special oil analysis device based on gathered optical fiber signal transmission and double-layer multi-CCD (Charge Coupled Device) detection, and the special oil analysis device is used for detecting the content of various metal elements in an oil sample. A rotating disc electrode drives oil to an analytical gap, spark discharge is generated by high voltage between two electrodes, and the metal elements in the oil sample are excited to generate emission spectra; and light with different wavelengths is transmitted to a grating to be split through optical fibers and then irradiated to different CCDs, and the content of multiple elements is obtained through light intensity signal detection and digital operation of spectral lines. The special oil analysis device comprises a light source part, an optical fiber transmission system, a light splitting system, a photoelectric detection system and a control circuit, wherein the light source part comprises a high-voltage generator, a rod electrode and the rotating disc electrode; and the light splitting system fixedly arranges an incidence gap, a concave grating and the CCDs on a Rowland circle device by virtue of a Paschen-Runge device. Compared with an existing instrument, the special oil analysis device disclosed by the invention has the characteristics of fast analysis, simultaneous detection on more than ten elements, direct sampling, no sample pretreatment, easiness for operation and convenience for maintenance.

Description

technical field [0001] The invention relates to a special device for oil analysis, in particular to a special device for oil analysis based on aggregated optical fiber signal transmission and double-layer multi-CCD detection. Background technique [0002] Traditional oil element analysis uses atomic absorption spectrometer or ICP spectrometer, which requires a lot of time for sample pretreatment, and a large amount of expensive auxiliary gases are required during the analysis process. Traditional elemental analysis instruments mainly use photomultiplier tubes as detectors, and then transmit signals to the spectroscopic system through lenses.
