The utility model relates to a visual sampling device for smoke dust particles in a flue. The visual sampling device is characterized in that an upper window and a lower window are arranged on the same side of the flue vertically; an illumination light source is positioned on the upper window, and outputs parallel light which enters the flue in an inclined downward manner; the lower window is assembled with a heat insulation air curtain; an image sensor is positioned outside the lower window; a smoke dust particle image is acquired through the heat insulation air curtain; an optical axis of the illumination light source is intersected with a horizontal image axial line of the image sensor in the middle of the flue; and information of the smoke dust particle image acquired by the image sensor is converted to digital data to be sent into an industrial control computer. According to the visual sampling device, visual acquisition of the smoke dust particles in the flue can be realized; furthermore, remote on-line real-time monitoring can be realized; the problem that smoke dust measurement is difficult is solved; and a forceful basis is provided for air pollution control.
