Abstract

The invention discloses an air pollutant detection device and an air pollutant detection method. The air pollutant detection device comprises a large particle separation system and a pollutant detection system; the large particle separation system comprises a gas purification cylinder, a piston and a gas input pipe; the piston is arranged in the gas purification cylinder and is used for discharging gas in the gas purification cylinder; a first control valve is arranged on the gas input pipe; a small particle pollutant monitoring system comprises a detection cylinder, a detector for detecting the concentration of small particulate matters and a gas discharging pipe; the gas discharging pipe is communicated with the detection cylinder; a second control valve is arranged on the gas discharging pipe; a gas outlet of the gas purification cylinder is communicated with the gas inlet of the detection cylinder through a capillary connecting pipe; a third control valve is arranged on the capillary connecting pipe; a filter membrane is arranged at the end part, connected with the gas inlet of the detection cylinder, of the capillary connecting pipe. The detection device performs treatment on to-be-detected air before detection by the large particle separation system to enable the detection result to be more accurate.

Description

technical field [0001] The invention belongs to the technical field of particle pollutant concentration detection in the air, and in particular relates to an air pollutant detection device and an air pollutant detection method. Background technique [0002] PM2.5 (Particulate Matter 2.5) refers to the general term for solid particles or liquid droplets less than or equal to 2.5 μm in the air. This kind of tiny particles can enter the lungs, so it is also called fine particles or particles entering the lungs. It is organic carbon compounds, sulfates, nitrates, ammonium salts, and elements such as sodium, magnesium, calcium, aluminum, iron, and even lead, zinc, arsenic, and cadmium. Because of their tiny particles and light weight, they can be suspended in the air for a long time, drifting and spreading over long distances, and pollute the atmosphere. [0003] Smog is the result of the interaction between specific climatic conditions and human activities. The economic and so...
