Abstract

The invention relates to an online atmospheric dust particle size measurement system, and belongs to the technical field of air measurement devices. The online atmospheric dust particle size measurement system comprises a lifter, a collector, a range finder, a particle size analyzer, a display and a control memory. The collector is mounted at the execution end of the lifter; the lifter is used fordriving the collector to lift; the range finder is used for measuring the distance between the collector and the ground; the particle size analyzer is used for detecting the particle size of the atmospheric dust collected by the collector; the display is used for displaying atmospheric environment parameters; the control memory is electrically connected with the lifter, the range finder, the particle size analyzer and the display, is used for controlling the lifter to lift according to the distance between the collector measured by the range finder and the ground, and is used for controllingthe display to display particle size data in real time according to the particle size of atmospheric dust collected by the collector detected by the particle size analyzer. The online atmospheric dustparticle size measurement system can realize collection and particle size detection of atmospheric dust samples with different heights, and is wide and accurate in measurement range.

Description

technical field [0001] The present application relates to the technical field of air measuring devices, in particular to an online atmospheric dust particle size measurement system. Background technique [0002] With the rapid development of the transportation industry and manufacturing industry, atmospheric dust pollution is becoming more and more serious. Because it is closely related to human respiratory health, especially in recent years, the smog weather that affects life in winter has further intensified, making the characteristics of atmospheric dust become a research hotspot again. , in which the particle size dynamics of atmospheric dust is the starting point of many studies. However, in the traditional research, only the dust collector is used to attach the atmospheric dust to the quartz membrane, and then the dust material is washed out from the quartz membrane to measure its particle size distribution. This method is not only time-consuming and labor-intensive, ...
