  • System and method for detecting concentration of free SiO2 in coal dust
    Patent number: 11940376
    Abstract: A system for detecting a concentration of free SiO2 in coal dust includes a first sampling tube and a second sampling tube for sampling the coal dust, a three-way control valve communicated with the first sampling tube and the second sampling tube respectively, a photoacoustic spectrometry detection device communicated with the three-way control valve through a connecting pipeline, and a SiO2 reaction tube for reacting SiO2 in the coal dust; and the SiO2 reaction tube is disposed on the second sampling tube. In the present disclosure, a coal dust sampling line is convenient to change by disposing the three-way control valve, and the first sampling tube and the second sampling tube are respectively communicated with the photoacoustic spectrometry detection device, so as to perform a differential accurate detection of the reacted CO content, and to obtain the SiO2 content.
