Specific implementation mode
The utility model is described in detail in conjunction with attached drawing：
Embodiment 1：As Figure 1-Figure 2,
A kind of spiral-flow type flue gas Fly ash sampling pipe, including exhaust duct 4, probe tube, eddy flow blast pipe 2 and sealing support case 9,
Probe tube includes straight pipe 1 and probe tube Taper Pipe section 5, and 5 diameter of probe tube Taper Pipe section gradually decreasees from top to bottom, eddy flow blast pipe
2 diameters are gradually reduced by front end to rear end, and multiple 2 longitudinal arrangements of eddy flow blast pipe are in 1 side wall of probe tube straight pipe, eddy flow air inlet
2 rear end of pipe with 1 side wall of probe tube straight pipe is tangent is connected to, and eddy flow blast pipe 2 is vertical with 1 tube wall of probe tube straight pipe, eddy flow
Spiral shell is equipped with sampling mouth 3 at 2 front-end port of blast pipe；Exhaust duct 4 is L-shaped, and long pipe section is installed in probe tube straight pipe 1,
Exhaust duct 4 be installed on the nozzle in probe tube straight pipe 1 be less than minimum eddy flow blast pipe 2, other end nozzle towards with gas
The identical direction in flow direction；8 bottom of sealing support case is equipped with balance adjustment bolt 10, and collection is provided in sealing support case 8
Grey bottle 9,5 lower end of probe tube Taper Pipe section, which deeply seals, to be communicated in support case 8 with collecting the gray bottle 9.Pacify in 5 centre position of probe tube Taper Pipe section
Equipped with seal gate valve 6, the progress of sealing device 7 is respectively provided between 5 lower end of probe tube Taper Pipe section and collecting the gray bottle 9 and sealing support case 8
Sealing.
In use, first choosing horizontal pipe or flue section, selected according to sampling section size and the air-flow physico-chemical property sampled
It takes suitable sampling mouth 3, while probe tube insertion depth is determined according to institute's sampling pipe sectional position, probe tube is from flue or pipe
Road bottom is inserted into, and insertion depth adjusts sealing support 8 bottom balance adjustment bolt 10 of case after determining, entire probe tube is made to keep hanging down
Straight stable state.
When the device fixes sampling, open seal gate valve 6, air-flow carry flying dust enter sampling mouth 3 again by eddy flow into
Air hose 2 accelerates, and justifying tangent directional velocity with 1 section of probe tube straight pipe enters, as shown in Fig. 2, to enter probe tube straight for air-flow
Air-flow is flowed downward along tube wall in a manner of helical trajectory after pipeline section 1, and under the influence of centrifugal force, flying dust, particulate matter then can
It is attached to wall surface eddy flow to move downward, then then enters probe tube Taper Pipe section 5, with the reduction of particulate matter, flying dust moving radius, then
The angular speed of screw slowly increases, and flying dust can be more close to avoid, and air-flow can be realized gas, gradually divide admittedly in center convergence
From.Because of whole device sealed bottom, and exhaust duct 4 is exported back to air velocity direction, and negative pressure is larger, and flying dust is bored in probe tube
5 bottom energy of pipe end gradually loses to fall to collecting the gray bottle 9, and air-flow goes out in central vortex flows back to pipeline by exhaust duct 4, real
Airless is revealed while now sampling.
When the sufficient flying dust of sampling, seal gate valve 6 can be closed, collecting the gray bottle 10 is taken out, other sampling bottles 9 is changed to or terminates
Sampling, withdrawing device.
Whole device is pure physical arrangement, not complicated electromagnetism, circuit system, safeguards, is easy to operate, and principle is simple,
But it may not apply to ultra-fine Fly ash sampling.
