ZDA-PDSI-02P type dilution channel sampler Introduction: The ZDA-PDSI-02P dilution channel sampler is mainly composed of a soot sampling gun (or a vehicle exhaust sampling probe), a four-channel sampling box, a primary dilution tank, a secondary dilution tank, a dilution chamber, and external connection components. Through different constant velocity sampling devices, the original flue gas is collected into the first dilution chamber and mixed with the first clean air in a certain ratio. After a uniform mixing by aerodynamics, it enters the residence tank to stay. According to different sampling requirements, one can be selected. Stage dilution, secondary dilution, to achieve different dilution ratios, using aerodynamics to simulate the natural diffusion, condensation, cooling, nucleation and reaction processes of particulate matter in the atmosphere. Finally, the uniform cutting sampling of PM10 and PM2.5 is completed by the flow balance control system. The equipment has achieved a number of invention patents and utility model patents.
