[0002] The particulate matter in the exhaust gas discharged from industrial stationary pollution sources is an important source of air pollution. Particulate matter is mainly composed of filterable particulate matter (FPM) and condensable particulate matter (CPM). According to research, the concentration of condensable particulate matter in the exhaust gas of some industries accounts for 49% of the total concentration of particulate matter. In my country, the sampling of exhaust gas particulate matter only stipulates In order to collect filterable particles, there is no requirement to collect condensable particles. The particle sampling instruments used in China only have the function of collecting filterable particles and do not have the function of collecting condensable particles. As a result, the monitoring results are lower than the actual results and the monitoring results are inaccurate. The pollutants in the exhaust gas cannot be well monitored, and the overall safety and practicability are generally not high. Therefore, for the improvement of the existing fixed pollution particle sampling device, a new type of fixed pollution filterable and condensable particles is designed. It is particularly important to change the above-mentioned technical defects and improve the practicability of the overall fixed pollution particle sampling device.
