  • the device the information of which is given in the description of RU 94023383 Al, is adopted as a prototype of this utility model.
  • X-ray radiation decays sharply in a liquid.
  • the X-ray fluorescence detector senses this radiation only from a thin layer of liquid adjacent to it ( ⁇ lmm). Therefore, with the opposite arrangement of the x-ray source and the X-ray fluorescence detector, the latter should be excited in the entire volume of the liquid. This necessitates the use of very powerful sources of x-ray radiation, which requires appropriate reinforced means of protection against this radiation.
  • the present utility model is based on solving the problem of reducing the power of an x-ray source of an x-ray fluorescence emitter and, accordingly, simplifying the design of the device as a whole.
  • this problem is solved due to the fact that in the X-ray fluorescence analyzer the sulfur content in liquid hydrocarbons, including a cuvette for placing the analyte, in the side wall of which there is a window closed by an X-ray transparent film, an x-ray source located on the side of the cuvette with side of the window, a detector of x-ray fluorescence emanating from the analyte, a spectral analyzer of the detector output signal, electronically calculates

  • the applicant has not identified sources containing information on technical solutions identical to this utility model, which allows us to conclude that it meets the “new” (N) criterion.
  • the required power of the x-ray source is significantly reduced, since the x-ray fluorescence radiation is not excited in the entire volume of liquid hydrocarbon, but only in a thin layer of liquid adjacent to the X-ray source and the X-ray fluorescence detector.
  • the X-ray fluorescence analyzer of the sulfur content in liquid hydrocarbons includes a source of 1 x-ray radiation, in a specific example, an X-ray tube type BX-7.

  • the device operates as follows. X-ray radiation emanating from source 1 penetrates through the film 4, which closes the window in the side wall of the cell 2, which contains the analyzed fluid. In the interaction of x-rays with liquid atoms, a secondary, so-called, x-ray fluorescence radiation occurs, the spectral composition of which is determined by the chemical composition of the analyzed liquid.
  • X-ray fluorescence radiation from a liquid layer 3 adjacent to the film 4 passes through the film 4 and enters the X-ray detector 5.
  • the detector captures the x-ray quanta that fall into it in the form of pulses of an electrical signal whose amplitude is proportional to the energy of the quanta.
  • the signal from the detector enters the spectral analyzer 6, which "cuts out” from the amplitude spectrum the interval corresponding to the energy of the sulfur line.
  • the digital signal from the spectral analyzer enters the electronic computing device 7, which controls the installation and determines the mass fraction of sulfur in the analyzed liquids.
  • the analysis results are sent to the information display unit S. In case of violation of the integrity of the film 4, the analyzed liquid will fall into the tray 9.

Abstract

Le modèle d'utilité appartient au domaine de la fluorescence X et peut s'utiliser pour déterminer la teneur en soufre de pétrole, de produits pétroliers et d'autres hydrocarbures liquides. L'analyseur à fluorescence X pour déterminer la teneur en soufre d'hydrocarbures liquides comprend une cuvette conçue pour accueillir la substance à analyser dans la paroi latérale de laquelle on a réalisé une fenêtre recouverte d'un film transparent aux rayons X, une source de rayons X, disposée adjacente à la cuvette, du côté de la fenêtre, un détecteur de fluorescence X provenant de la substance à analyser, un dispositif de calcul et une unité d'affichage d'informations ainsi qu'une source de rayons X et un détecteur de fluorescence X provenant de la substance à analyser, du même côté par rapport à la cuvette. Ce schéma permet de réduire la puissance de l'émetteur de rayons X et, par conséquent, les dimensions, la consommation de matériaux et le coût du dispositif en général.
