Abstract

The invention discloses an on-line detection method for potassium salt composition. Firstly, the surface of potassium salt is flattened; then, an X fluorescent element on-line measurement mechanism is used to measure the element composition of potassium salt; Data; according to the measurement results of the potassium salt water content, the influence of water changes on the measurement results of the X fluorescent element online measurement mechanism is accurately compensated, and according to the fluctuation of the potassium salt material amount, the distance compensation correction method is used to perform distance compensation correction on the X fluorescence intensity.

Description

technical field [0001] The invention relates to the field of component detection of industrial materials, in particular to an online detection method for potassium salt components. Background technique [0002] China's soluble potassium salt resources are seriously scarce, and the proven reserves are mainly potassium chloride. Most of the deposits have disadvantages such as poor construction conditions, low potassium grade, and high development costs. 95% of the potassium salt in the world is used as fertilizer. China is a large agricultural country and consumes a lot of potassium fertilizer. It has been mainly relying on imports to maintain demand. In recent years, with the development of the potassium salt industry, the self-sufficiency rate of domestic potassium salt has been continuously improved, but the high-grade potassium salt is still too dependent on imported supplies. [0003] In order to improve the utilization rate of soluble potassium resources, various countr...
