Abstract：An efficiency evaluation system of PM2.5 particle separation device based on static chamber method was established firstly. In the developed evaluation system, the different aerosol environment conforming to the measurement requirements was generated separately in the static chamber by atomizing 8 kinds of different size polystyrene particle samples. By utilizing an aerodynamic diameter spectrometer, particle concentration before and after particle separation device was measured to obtain the penetration curve of the particle separation device after data fitting. Then, evaluation experiments for a domestic and an imported particle separation devices were carried out to obtain their collecting efficiency. The study is helpful for the production and use of particle separation device, and reference for the subsequent evaluation of other kinds of particle separation devices.
