となつている。 As shown in FIG. 1, the measurement of the above dust is usually carried out using a filter paper or a detection part A, an SO 2
This is done by connecting an absorption bottle B, a mist remover C, a vacuum pump D, a flow meter E, a gas meter F, etc. in sequence and suctioning an exhaust gas sample, but in this case, the sampling tube 1' is simply a small diameter fixed tube. As a result, dust adheres and accumulates inside, making it difficult to measure the actual amount of distribution.

ある。 In order to eliminate the above-mentioned drawbacks, this device prevents the deposition of dust by inducing resonance in the sampling tube at any time or continuously. In Figure 2, reference numeral 1 denotes a sampling tube, which is supported by a spring 4 inside an outer tube 3, which is provided in advance almost orthogonally to the duct 2, with a gap maintained between it and the inner surface of the outer tube 3. There is. This outer tube 3 is
A partition plate 5 made of a soft thin film is placed inside the duct 2 near the boundary to isolate it from the inside of the duct 2, and a resonance mechanism 6 is provided at a suitable location on the outside to vibrate the sampling tube 1 inside. It's summery. In this embodiment, the resonance mechanism 6 is formed by a hammer 6a consisting of a solenoid coil operated by an AC power source and a movable core, and the lower end of the movable core strikes the outer surface of the sampling tube 1 with fine strokes. 7 is a control panel for the resonance mechanism 6.
次に第３図は、共振機構６として振動機６ｂを

A vibrator 6b is provided, and a dust trap 8 and a dust monitor 9 are also installed in a part of the sampling tube.
is installed to prevent coarse particles from being brought into the measuring instrument, and after a certain period of time, it is removed and quantified separately.Other parts are shown with the same symbols as in Fig. 2.

ができる。 As explained above, in this device, the sampling tube 1 is supported by the spring 4, and resonance is induced therein by the resonance mechanism 6, so that the dust inside the sampling tube 1 is shaken off and fine particles are removed. Particles can be sucked as they are by the vacuum pump and transferred to the filter paper or the detection unit, and coarse particles can be moved forward little by little by gravity due to the vibration of the sampling tube 1 and introduced into the dust trap 8, etc., thus eliminating all the inconveniences of the conventional method. can do.
