The device comprises a top cover, a sleeve, a filter drum, a bottom cover, an inlet guide pipe, a constant-speed sampling head, an outlet connecting pipe, a connecting sleeve, a sealing soft plate, a sealing cover plate and a sleeve cover, wherein the constant-speed sampling head and one end of the inlet guide pipe are in threaded connection, the other end of the inlet guide pipe and a smoke tangential inlet of the top cover are in threaded connection; the filter drum is fixed in the sleeve through the top cover and the bottom cover, an opening end of the filter drum sleeves the filter drum interface and is sealed; the bottom cover is provided with a shallow conical groove; the outlet connecting pipe and the connecting sleeve and a smoke educing hole on the top cover are in threaded connection; one sealing soft plate sleeves the connecting sleeve, the sealing cover plate is arranged on the sealing soft plate, the sleeve cover is arranged at the outlet of the connecting sleeve for fixing the outlet connecting pipe. The problem that the acquisition amount is reduced due to falling dust is avoided when the device is used for vertical sampling, the accidental error of the measurement is reduced, and the device also cane used for sampling in a horizontal direction. |
