Embodiment Construction

[0009] Referring to the accompanying drawings, the X-ray tube 1 is fixed on the side of the support frame 2, the collimator 7 is aligned with the oblique through hole 6 on the support frame, and the sample cup 3 arranged at the sample window at the top of the support frame is covered by the inner and outer cups. It is composed of a layer of polycarbonate film, the proportional counter 8 and the probe 9 are arranged directly under the sample cup, the axis of the probe is collinear with the axis of the sample cup, the center line of the oblique through hole intersects the axis of the probe, and the angle is 45°. In the sample cup, there is a secondary optical filter 10 between the probe and the sample window, and there is a primary optical filter at the front end of the collimator. The stop post 4 is horizontally and vertically inserted or withdrawn from the oblique through hole driven by the motor 5 and the gear-rack transmission mechanism, and the transmission mechanism is prov...

Abstract

The invention discloses a photoelectric conversion device for detecting sulfur, and is especially applicable to the field of analytical instruments for detecting the content of sulfur element in crude oil and derivative products by energy dispersive X-ray fluorescence spectrometry. The invention integrates the optical, mechanical and electrical technology, and mainly comprises a bracing frame, an excitation light source located at one side of the bracing frame, a sample cup at the top of the bracing frame, a detector system below the sample cup, and a bumping post system controlling the on-off of the light path of the X-ray. The device has a compact structure, is convenient to use, and can rapidly detect the high or low content of sulfur element in a tested sample.

Description

technical field [0001] The invention relates to a photoelectric conversion device for measuring the content of sulfur element, and is particularly applied in the field of a type of analytical instrument for measuring the content of sulfur element in crude oil and its derivative products by using energy dispersion-X-ray fluorescence spectrometry. Background technique [0002] When analyzing and determining the content of sulfur in crude oil and its derivative products, the classic microcoulomb comprehensive analysis method and ultraviolet fluorescence technology were used in the past. The classic microcoulomb comprehensive analysis method is cumbersome and requires many additional facilities, such as electrolytic cells, stirrers, high-temperature cracking furnaces, etc., and it is difficult to accurately determine high-content sulfur. When using fluorescence technology to determine sulfur content, additional facilities such as high-temperature cracking furnace, quartz crackin...
