Description

Technical Field

[0001] This utility model belongs to the field of total suspended particulate matter detection technology, and specifically relates to a device for detecting total suspended particulate matter in the atmosphere. Background Technology

[0002] Total suspended particulate matter (TSP) refers to solid or liquid particles with a diameter of less than 100 micrometers in the air. These particles can originate from natural sources (such as volcanic eruptions and sandstorms) and anthropogenic sources (such as industrial emissions and vehicle exhaust). TSP has a significant impact on environmental quality, human health, and climate, making its effective monitoring crucial. Various methods exist for its detection, with the gravimetric method being a relatively traditional approach. This involves collecting air samples over a specific time period, filtering them through a filter membrane, weighing them, and calculating the mass concentration of particulate matter per unit volume of air. However, most common detection devices can only achieve air adsorption at a single location or through multiple fixed sets of pipes. This results in a limited range of collected air and insufficient representativeness of the collected samples. The density of TSP in some locations may be higher or lower than expected, affecting the final detection results and leading to inaccurate readings.

[0003] In summary, the total suspended particulate matter detection device with a limited range of air adsorption and collection has some problems in use. Therefore, it is hoped that a new structure can be proposed to solve the above-mentioned technical problems. Utility Model Content
