Problems solved by technology

[0003] At present, the cascade impact particle collection device is mainly used to collect particles of different particle sizes (especially submicron particles). The sample is scattered at multiple points, which brings difficulties to the subsequent chemical analysis
Moreover, the series design structure adopted by the series impact particle collection device makes it easy to interfere with other levels if a certain level fails.
In addition, due to the characteristics of the cascade impact particle collection device using the sampling medium as the particle impact plate, it is impossible to apply viscous substances such as silicone oil to the particle impact plate to reduce the phenomenon of particle rebound, resulting in the device’s capture of particles with a rated particle size low efficiency

Abstract

The invention relates to an atmospheric particulate matter collection device, in particular to a wide-range multi-particle-size particulate matter parallel collection device which comprises a PM10 sampling head, wherein a blank tube connector and five particle matter cutters, namely, PM2.5, PM1.0, PM0.7, PM0.44 and PM0.25 cutters, are respectively connected with the lower end of the PM10 sampling head; the blank tube connector and the five particle matter cutters are respectively connected with a filtering film clamp sampling unit; each filtering film clamp sampling unit is connected with a flow control system and a sampling air pump; the flow control system is connected with an intelligent economic control system. The atmospheric particulate matter collection device provided by the invention, has the characteristic that particulate matters of multiple particle sizes from micron to submicron can be simultaneously captured, and in addition, the parallel collection device with uniform collected sample distribution and high capturing efficiency can be applied to study on climate, environments and healthcare effects of particulate matters of different particle sizes.

Description

technical field [0001] The invention relates to a device for collecting particles in an atmospheric environment, in particular to a device for collecting particles in parallel with multiple particle sizes in a wide range. Background technique [0002] Particulate matter is not only an atmospheric pollutant that affects air quality and endangers human health, but also has an important impact on the formation of haze weather and climate change due to its direct and indirect effects on radiation. Particle size is one of the important physical properties of atmospheric particulate matter, and is a key parameter affecting the climate, environmental effects and human health of particulate matter. For example, according to the Mie scattering principle, it can be known that particles (0.4-0.7 μm) with wavelengths similar to solar radiation have the highest light scattering efficiency. The respiratory system has different deposition mechanisms, so particles of different particle siz...
