Description

Technical Field

[0001] The invention relates to the field of air quality monitors, and in particular to an online monitoring instrument for ambient air particles. Background Art

[0002] With the acceleration of global industrialization, the problem of environmental air quality is becoming increasingly serious. PM2.5 and PM10 particles in the air not only have a negative impact on the ecological environment, but also cause many harms to human health. Long-term exposure to high concentrations of particulate matter may cause respiratory diseases, cardiovascular diseases, etc., seriously affecting the quality of life and life expectancy of the public. Therefore, it is particularly important to develop efficient online monitoring instruments to monitor air quality in real time.

[0003] At present, traditional environmental air particulate matter monitoring methods mainly rely on laboratory analysis and manual sampling. These methods are not only time-consuming, but also cannot meet the needs of real-time monitoring. At the same time, when used in places such as outdoors where it is not convenient to supply electricity, although some monitoring instruments are equipped with photovoltaic components, when placed outdoors for a long time, more dust and impurities will adhere to the surface of the photovoltaic panels, thereby reducing the power generation efficiency of the photovoltaic panels. In addition, the monitoring height of traditional outdoor environmental air online detection instruments is mostly fixed. Therefore, when conducting real-time monitoring, the real-time monitoring data will have certain errors due to different monitoring heights.

[0004] Therefore, in order to solve the problems existing in the above-mentioned technology, people in this field have specially proposed an online monitoring instrument for ambient air particulate matter. Summary of the invention
