Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of air treatment, in particular to an automatic sampling device for air treatment. Background Art
[0002] Particulate matter in the atmosphere (also called aerosols, or simply atmospheric particulate matter) is ubiquitous in nature and daily life, such as dust, bacteria, haze, smoke, etc. The sources of atmospheric particulate matter can be divided into natural sources and anthropogenic sources. Natural sources include ground dust, volcanic ash released by volcanic eruptions, sandstorms, etc. Anthropogenic sources include smoke generated by the combustion of various fuels, material particles emitted by industrial production, automobile exhaust, etc. The vast majority of atmospheric particulate matter suspended in the atmosphere is formed in various industrial and agricultural production processes. Different atmospheric particulate matter has different aerodynamic equivalent diameters (also called particle sizes). Particles with a diameter less than 100μm are called total suspended particulate matter, those less than 10μm are called inhalable particulate matter and are represented by PM10, and those less than 2.5μm are called respirable particulate matter and are represented by PM2.5. The smaller the particle size of atmospheric particulate matter, the greater the impact on human health. In order to detect the particle composition in the atmosphere and facilitate targeted treatment, it is necessary to use a collection device to collect atmospheric particles for detection and analysis.
[0003] Most current collection devices use an air pump to draw gas into the device, where the particles are intercepted on a filter plate, which is then removed to collect the particles. This operation is rather cumbersome and cannot achieve automated collection of particles. Utility Model Content
