Problems solved by technology

[0004] However, in the device and method for measuring the mass concentration of infrared interference smoke screens using smoke screen test cabinets and laser particle size distribution instruments proposed by Wang Xuanyu and others, the concentration sampler is required to be in the infrared smoke screen test cabinet when measuring the mass concentration of infrared interference smoke screens. The interference smoke screen is strictly homogeneous, but there is a lack of means and methods to ensure that the infrared interference smoke screen is strictly homogeneous, and it is impossible to ensure that a strictly homogeneous infrared interference smoke screen is collected during the measurement process
Therefore, there is a large measurement error in the scheme proposed by Wang Xuanyu et al.

Abstract

The invention discloses a mass concentration measuring device and method of an infrared-interfered smoke screen in vacuum. The mass concentration measuring device comprises a vacuum tank, a pipeline, a vacuum pump, a flow meter and an ultrathin glass fiber filter membrane; the vacuum tank is connected with the pipeline through the vacuum pump; the ultrathin glass fiber filter membrane is arranged at the position of the joint of the pipeline and the vacuum pump; the flow meter is arranged on the pipeline; the vacuum pump is used for adjusting vacuum degree in the vacuum tank; the ultrathin glass fiber filter membrane is used for collecting smoke screen particles; an ignition device is arranged on the upper portion of the vacuum tank and is used for igniting a smoke producing agent of an infrared-interfered smoke screen to produce the infrared-interfered smoke screen. By the arrangement, measuring error is reduced, and accuracy in measurement is improved.

Description

technical field [0001] The invention relates to the technical field of infrared interference smoke screen effect detection, in particular to a mass concentration measurement device and method for infrared interference smoke screen in vacuum. Background technique [0002] The mass concentration of infrared interference smoke is an important basis for predicting and evaluating the smoke formation efficiency of infrared interference smoke smoke agents and the settling velocity of smoke particles. It is an important reference index in the research and development of infrared interference smoke smoke agents. [0003] Wang Xuanyu and others used a smoke test cabinet and a concentration sampler to measure the mass concentration of infrared interference smoke. Among them, the middle of the smoke screen test cabinet is a rectangular parallelepiped with a sealed structure. The rear wall is equipped with a small door for the experimenters to enter and exit. There is an exhaust port in ...
