Component detection device used for smoke dust particulates and based on double-pulse laser-induced breakdown spectroscopy

The invention belongs to the technical field of detection of smoke particulates, particularly relates to a component detection device used for smoke dust particulates and based on double-pulse laser-induced breakdown spectroscopy. The invention aims to overcome the problems that common measurement means are tedious, complex and high in cost, standard measurement is difficult to achieve, and smoke is not filtered in the prior art. According to a scheme provided by the invention, the component detection device comprises a machine body, a first fixed laser body, a second fixed laser body, a retarder, a first total reflection mirror, a second total reflection mirror, a spectrometer, an enhanced charge coupler, an optical fiber probe, a computer, an air inlet, a focusing mirror, an air filter membrane, a rotating table and an air pump. The component detection device used for smoke dust particulates and based on the laser-induced breakdown spectroscopy not only can rapidly detect the components of particulate matte
