Portable pollution sources dilute passageway aerosol sampling device and fluidization cabin

The utility model provides a portable pollution sources dilute passageway aerosol sampling device and fluidization cabin, including the sampling mouth, the sampling pipe, the pitot tube, heating device, the diluter, the particulate matter cutterbar, the fluidization cabin, the desicator, a filte, the tee bend, the solenoid valve, the aspiration pump, the circulating air return circuit, a single -chip microcomputer, pipeline temperature sensor ts, pipeline pressure sensor ps, pitot tube differential pressure sensor triangle P1, temperature sensor tg, temperature sensor tc, pressure sensor pc, flow sensor qc, pressure sensor pr, flow sensor qr, the keyboard, the display, communication interface. The utility model discloses can dilute the sample gas of high temperature, high humility, high concentration in the pipeline, realize sampling of sample gas constant speed and particulate matter constant current separation, with the aerosol sample collection in the pipeline to the fluidization cabin in, at the fluidization under -deck, the particulate matter is overcome the gravitational settling effect and is in flow state in the aerosol.
