Portable aerosol sampling device for pollution source dilution channel and fluidization cabin

The invention relates to a portable aerosol sampling device for a pollution source dilution channel and a fluidization cabin. The portable aerosol sampling device comprises a sampling nozzle, a sampling tube, a pitot tube, a heating device, a diluter, a particulate matter cutter, a fluidization cabin, a dryer, a filter, a tee joint, a solenoid valve, an air pump, a circulating gas loop, a single chip microcomputer, a pipeline temperature sensor Ts, a pipeline pressure sensor Ps, a pitot tube differential pressure sensor deltaP1, a temperature sensor Tg, a temperature sensor Tc, a pressure sensor Pc, a flow sensor Qc, a pressure sensor Pr, a flow sensor Qr, a keyboard, a display and a communication interface. According to the portable aerosol sampling device for the pollution source dilution channel, high-temperature, high-humidity and high-concentration sample gas in the pipeline is diluted, the sample gas can be subjected to equal speed sampling and particulate matters are subjected to constant current separation; the aerosol sample in the pipeline can be collected into the fluidization cabin, and the particulate matters in the aerosol overcome the gravity settling action and are in a flowing state in the fluidization cabin.
