Special X-ray fluorescence energy spectrometer for high-precision cement industry

Abstract

The invention relates to the technical field of X-ray fluorescence detection and particularly discloses a special X-ray fluorescence energy spectrometer for the high-precision cement industry. The special X-ray fluorescence energy spectrometer comprises an X light pipe, a diffraction crystal, a sample stage and a detector, wherein the diffraction crystal is a full-focus bent crystal with double curved surfaces and is prepared from a Ge(111) crystal; the X light pipe adopts an Ag target material; the diffraction crystal monochromatizes an Ag:La ray of an X light pipe primary spectrum and focuses the Ag:La ray to a sample detection surface to stimulate light elements difficult to stimulate in a sample. Meanwhile, the X light pipe primary spectrum stimulates fluorescent rays GE:Ka and Ge:Kb of Ge to stimulate heavy elements easy to stimulate in a sample. The continuous background of a detector is very low, and all elements of raw materials in the cement production process can be accurately analyzed.

Description

technical field [0001] The invention relates to the technical field of X-ray fluorescence detection, in particular to a high-precision X-ray fluorescence spectrometer dedicated to the cement industry. Background technique [0002] The industrial process of cement production is to mix limestone, clay, iron powder and other raw materials in a certain proportion through the batching control system to obtain cement raw meal through raw meal grinding, and then calcinate the cement raw meal in a cement kiln to obtain cement clinker. The process of mixing raw materials, admixtures, retarders, etc. according to a certain ratio and grinding them through cement mills to obtain finished cement. Raw materials, raw materials, clinker and cement in the industrial process of cement production require chemical composition analysis. First of all, the ratio of raw materials should be set according to the chemical composition of the raw materials, and the ratio of raw materials must be adjust...
