Abstract

The invention relates to the technical field of industrial automatic measurement, and provides an online detection system of element content of industrial solid powder, aiming at solving the problems that the commonly used detection method cannot meet the requirement on fast and real-time online detection of contents of multiple elements in industrial solid powder, and the LIPS (Laser Induced Plasma Spectroscopy) technology is not applied to online detection of contents of elements in industrial solid powder successfully. The online detection system of element content of industrial solid powder comprises a sampling channel, a measurement room, an LIPS detector, a correction device, a sample discharging channel and a working gas generator for supplying gas for the whole detection system, and realizes application of the LIPS technology in online detection of elements in industrial solid powder by a reasonable and compact structure. Proved by experiments, the detection system provided bythe invention can detect multiple elements in the industrial solid powder online rapidly in real time so as to guide workers to adjust the production condition in time to improve the production efficiency.

Description

technical field [0001] The invention relates to the technical field of industrial automatic measurement, in particular to an on-line detection system for element content of industrial solid powder. Background technique [0002] At present, chemical analysis, X-ray fluorescence spectrometry and gamma ray analysis are commonly used in the industry for the quantitative analysis of elements in solid powder. However, the process of chemical analysis is complex and time-consuming, which cannot guarantee the timeliness of industrial online control; X-ray fluorescence spectrometry must be equipped with special sample preparation equipment, and the types of detected elements are limited; the disadvantage of gamma-ray analysis is that the detection results are subject to high The fluctuations in the content of atomic number elements (such as iron) have a greater impact, the price of radioactive sources is expensive, and its maintenance and daily care are also difficult, and there are ...
