Abstract
The utility model discloses a photoelectric conversion device used for detecting sulphur, which is particularly applied in the field of analytical instruments adopting energy chromatic dispersion-X fluorescence spectrum principle for detecting sulfur content in raw oil and derivation product of the raw oil. The photoelectric conversion device provided by the utility model realizes optical, mechanical and electronic integration, mainly comprises a support frame, an excitation light source system positioned on one side of the support frame, a sample cup arranged at the top part of the support frame, a detector system arranged below the sample cup, and a blocking pillar system used for controlling the break-make of an X-ray optical path, and has the advantages of compact structure, convenience in use, and capability of detecting the high or low content of the sulphur in a to-be-tested sample quickly and accurately.
Description
Technical field
The utility model relates to a kind of photoelectric conversion device of measuring element sulphur content, is applied to adopt energy dispersion especially---an alanysis instrument field of element sulphur content in x-ray fluorescence spectrometry crude oil and the derived product thereof.
Background technology
In assay determination crude oil and derived product thereof, during element sulphur content, adopted classical microcoulomb comprehensive analysis method and Ultraluminescence technology in the past.Classical microcoulomb comprehensive analysis method is more loaded down with trivial details, and additional facilities is many, need use electrolytic cell, and stirrer, high-temperature cracking furnace etc., and be difficult to accurately measure the sulphur of high-load.When the utilization fluorescent technique is measured sulfur content, need additional facilities such as high-temperature cracking furnace, crystalline silica cracking tube, carrier gas, the pre-process of sample is required than higher.The instrument volume that is used for above these two kinds of methods is bigger, carries inconvenience.Adopt energy dispersion---during x-ray fluorescence spectrometry element sulphur content, under the x-ray source irradiation, element sulphur in the sample absorbs energy and inspires XRF, detect XRF energy spectrogram by proportional counter and multichannel analyzer, thereby quantitative test goes out the content of element sulphur in the sample.Energy dispersion---x-ray fluorescence spectrometry speed is fast, measure that concentration range is wide, sample shape arbitrarily and be not destroyed.The method analytical instrument industry at home is a novel developing field.But also be not applied to the perfect relevant apparatus of standard of this method at present.
The utility model content
The purpose of this utility model provides a kind of compact conformation, easy to use, employing energy dispersion---the survey sulphur photoelectric conversion device of element sulphur content in X-ray fluorescence spectra technical measurement crude oil and the derived product thereof that effect is good.
The technical solution of the utility model is: survey sulphur photoelectric conversion device light harvesting, machine, electric components is in one, mainly by bracing frame, be located at the excitation light source system of bracing frame one side, be located at the sample cup and the detector system below the sample window at sample window place, bracing frame top and control the open close bumping post system formation of X ray light path in the excitation light source system, described excitation light source system is provided with X-ray tube and collimating apparatus, the X ray light path is one to favour sample cup, port is facing to the cup oblique through hole at the end, described detector system is provided with probe and proportional counter, the axis of probe and the center line of above-mentioned oblique through hole intersect in the sample cup, and described bumping post system is made up of the bumping post and the motor transmission mechanism of the oblique through hole of vertical insertion.
Further scheme is: the cup end of described sample cup is one deck printing opacity, corrosion resistant film, and this film is clipped between the inside and outside glass holder; Place secondary optical filter between described sample window and the probe, the collimating apparatus front end is placed elementary optical filter; The angle of described oblique through hole center line and probe axis is 45 °; Motor transmission mechanism in the described bumping post system is gear, the rack mechanism that servomotor drives, and is provided with stops and travel switch in this mechanism.
Adopt technique scheme, excitation light source system, sample cup, detection system, bumping post kinematic train combine in bracing frame and are integral, and compact conformation, volume are little.X ray emission light path and X fluorescence are accepted light path and are converged at the sample cup axis, are easy to realize the transmission and the acceptance of light path, and the transmission distance is short, and loss is little.Bumping post transmission adopted rectilinear motion, implementation procedure is simple, and the response time is short, and moment can be finished the light path prevention and be opened action.Sample cup has big volume, and it is convenient to pick and place sample, the requirement of sample shape arbitrarily and be not destroyed, sample can be a liquid, also can be solid, sample size can be more, also can lack, thereby easy to use.The film of sample cup is made by certain material, printing opacity, flexible, corrosion-resistant, and contaminated samples not.Whole device effectively shields X ray in bracing frame, avoids the damage to the operator.Use this photoelectric conversion device, can accurately, fast, conveniently realize photoelectric converting function, thereby measure the content of sample element sulphur.
