MZ-1 type neutron online coal quality analyzer and relative measurement method

Abstract

The invention discloses an MZ-1 type neutron online coal quality analyzer and a relative measurement method. The analyzer comprises a box body, a neutron generator, two gamma ray detectors, a calibration coal box, a to-be-detected coal box channel and a distribution box; and the neutron generator, the gamma ray detectors, the calibration coal box and the to-be-detected coal box channel are all assembled in the box body. The method comprises the following steps: 1, giving a chemical analysis value of a calibration coal sample; 2, solving a linear relationship among the contents of organic hydrogen, organic oxygen and carbon elements in the corresponding coal types; 3, putting the calibration coal sample into the calibration coal box; 4, finding out a linear relation Mc / Ms = k * (Ac / As) + b;5, calculating the carbon content Mc in the coal sample to be detected; 6, comparing the measurement data with the reference data by using a computer; and 7, completing guidance of a production link.The analyzer and method have the beneficial effects that the measurement precision is improved, so that the requirement of coal quality analysis on precision is met.

Description

technical field [0001] The invention relates to a coal quality analyzer and a relative measurement method, in particular to an MZ-1 neutron online coal quality analyzer and a relative measurement method. Background technique [0002] At present, the coal quality analysis technology used in the existing coal industry production mainly adopts laboratory chemical analysis or X-ray fluorescence analysis. These two methods need to collect samples of raw coal on site (sampling process), and then make standard samples that meet the analysis requirements (sample preparation process). After sampling and sample preparation, the experimenters analyze the samples and obtain the analysis results. The whole process takes a long time, and during this time, a large amount of raw coal enters the production link through the conveyor belt. Therefore, traditional methods cannot quickly give analysis results and lack effective guidance for the production process. [0003] At present, the more...
