The invention discloses a device and method for detecting particles in a pipeline. The two opposite sides of the side wall of the pipeline are provided with a first transparent window and a second transparent window respectively, light is emitted into the pipeline by a light source through the first transparent window, when there are particles passing through gas of the pipeline, the effective optical path of the transmitted light passing through the particles is changed, and therefore the light intensity of the transmitted light detected by a photoelectric detecting module through the secondtransparent window is changed, and the number of the particles passing through the pipeline can be determined according to the changing frequency of the light intensity; meanwhile, the size of the particles can be obtained according to the changes of the light intensity; the problem that the number and size of the particles passing through the pipeline cannot be precisely detected in the prior artcan be solved, and the de
