Abstract
Disclosed are a mine dust real-time detection system based on double-photoacoustic spectrometry and a detection method. The mine dust real-time detection system based on double-photoacoustic spectrometry includes a first sampling unit, a first photoacoustic detection cavity, a second sampling unit, a second photoacoustic detection cavity, a signal unit and a processing unit; the first sampling unit is used for sampling in respective, the first photoacoustic detection cavity provides a photoacoustic effect field to substances sampled by the first sampling unit, the second sampling unit is used for sampling in respective, the second photoacoustic detection cavity provides the photoacoustic effect field to substances sampled by the second sampling unit, the signal unit is used for providing a laser signal, and the processing unit is used for collecting and processing a photoacoustic signal.
