Abstract

The invention discloses a particle size distribution measuring device and method for infrared interference smoke screen in vacuum. The device comprises a vacuum tank, a pipeline, a vacuum pump and a multi-layer filter membrane serial piece; the vacuum tank and the vacuum pump are connected through the pipeline; the multi-layer filter membrane serial piece is arranged at the junction of the pipeline and the vacuum pump; the vacuum pump is used for adjusting the vacuum degree in the vacuum tank; the multi-layer filter membrane serial piece comprises multiple layers of glass fiber filter membranes, and is used for collecting smoke particles; the multiple layers of glass fiber filter membranes are arranged from large to small according to pore diameters in sequence; an igniting device is arranged at the upper portion of the vacuum tank, and is used for igniting an infrared interference smoke screen smoke agent, and therefore smoke is generated. According to the particle size distribution measuring device and method for infrared interference smoke screen in vacuum, the measurement error is reduced, and the measurement accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of infrared interference smoke screen effect detection, in particular to a particle size distribution measurement device and method for infrared interference smoke screen in vacuum. Background technique [0002] The particle size distribution of infrared interference smoke is an important physical quantity to characterize the infrared extinction characteristics of infrared interference smoke in vacuum, and it is also a necessary parameter for quantitative calculation of infrared interference smoke shielding performance and interference performance. Significance. [0003] The extinction coefficient of infrared interference smoke has an important influence on the shielding performance of infrared interference smoke, and the size of smoke particles in infrared interference smoke is an important factor affecting the extinction coefficient. Therefore, in the development of infrared interference smoke smoke agent...
