Background technology
According to the requirement of gathering for gaseous state in the pollution source and dirt attitude fluoride in the mensuration ion selective electrode method of the national standard HJ/T67-2001 atmosphere stationary pollution source fluoride of smoke dust sampling; In order from pipeline, to obtain representational sample, adopt isokinetic sampling's method to gather fluoride.The at present domestic sampling rifle that in the pipeline particulate pollutant is measured, uses mainly contains following several kinds of functions: flue dust (flue gas) sampling, the test of cigarette temperature, water capacity test, temperature test, pitotpre ure test etc.; And the filter cylinder for sampling of existing sampling rifle, accurately no consumption obtain in the pollution source all with gaseous state and the solid-state fluoride that exists.
Summary of the invention
Deficiency to the prior art existence; Technical matters to be solved by this invention is; The special-purpose sampling pipe of gaseous state in a kind of flue and dirt attitude fluoride is provided; The structural design of sampling pipe and sampling head through uniqueness, accurately no consumption obtain in the pollution source allly with gaseous state and the solid-state fluoride that exists, eliminate the measuring error that residual smoke causes.
For solveing the technical problem; The technical scheme that the present invention taked is: the special-purpose sampling pipe of gaseous state and dirt attitude fluoride in a kind of flue; It comprises combination sampling head, RTD, pitot tube connecting pipe, flue gas connecting pipe, protection tube, handle and handle; The combination sampling head is combined by pitot tube and flue gas sampling head, and the flue gas sampling back of head connects the flue gas connecting pipe; Protection tube links to each other with handle, and RTD, pitot tube connecting pipe, flue gas connecting pipe insert in the handle through protection tube; Handle is provided with handle; Be provided with filter cylinder in the flue gas sampling head; Said flue gas sampling back of head is provided with the filter cylinder frame adaptive with filter cylinder, and said filter cylinder places the filter cylinder frame; The outside of said flue gas sampling back of head and flue dust connecting pipe is wound with the heating tape.
Said filter cylinder frame is processed by corrosion resistant plate or stainless (steel) wire that the surface is uniformly distributed with aperture.
The special-purpose sampling pipe of gaseous state and dirt attitude fluoride in the above-mentioned flue, it also at the separable hanger of handle arranged outside, is provided with absorption bottle on the hanger.Said absorption bottle is impact type absorption bottle or porous glass plate absorption bottle.
The special-purpose sampling pipe of gaseous state and dirt attitude fluoride is rational in infrastructure in the flue of the present invention, gaseous state in the flue and the sampling of dirt attitude fluoride is combined the overall process heating; Prevent to produce condensate water, avoid fluoride to be dissolved in condensate water, cause measuring error, and built-in filter cylinder frame; When smoke moisture is bigger, cause when filter cylinder is broken to be difficult for taking out, the filter cylinder frame can be brought into play protection and the fixedly effect of filter cylinder, its inner highly versatile that connects; Easy to maintenance, simple appearance, telotism; In light weight, use easy to carryly, measurement of soot and dust concentration is accurate.

Embodiment
Embodiment 1
Like Fig. 1,2, shown in 3; The special-purpose sampling pipe of gaseous state and dirt attitude fluoride in a kind of flue; It comprises combination sampling head 1, RTD 2, pitot tube connecting pipe 5, flue gas connecting pipe 4, protection tube 6, handle 11 and handle 13; Combination sampling head 1 is combined by pitot tube 8 and flue gas sampling head 7, and flue gas sampling head 7 rear portions connect flue gas connecting pipe 4; Protection tube 6 links to each other with handle 11, and RTD 2, pitot tube connecting pipe 5, flue gas connecting pipe 4 insert in the handle 11 through protection tube 6; Handle 11 is provided with handle 13; Be provided with filter cylinder 15 in the flue gas sampling head 7; Said flue gas sampling head 7 rear portions are provided with the filter cylinder frame 25 adaptive with filter cylinder 15, and said filter cylinder 15 places filter cylinder frame 25, and filter cylinder frame 25 is processed by corrosion resistant plate or stainless (steel) wire that the surface is uniformly distributed with aperture.The outside of said flue gas sampling head 7 rear portions and flue dust connecting pipe 4 is wound with heating tape 26.At handle 11 arranged outside hangers 20, three absorption bottles 21,22,23 are set on the hanger 20, absorption bottle is impact type absorption bottle or porous glass plate absorption bottle.The sampling pipe of present embodiment twines heating tape 26 in the outside of flue gas sampling head 7 rear portions and flue dust connecting pipe 4, and the omnidistance heating that can guarantee to sample avoids producing the condensation of moisture phenomenon.Filter cylinder frame 25 is arranged on flue gas sampling head 7 inside, when needing replacing heating tape 26 perhaps to keep in repair, can directly front end end cover 27 be screwed off.
Embodiment 2
The special-purpose sampling pipe of gaseous state and dirt attitude fluoride and the difference of embodiment 1 are in the flue of present embodiment, and two porous glass plate absorption bottles are set on the hanger 20.Remaining structure is all identical.
Above-mentioned special-purpose sampling pipe, it so that the temperature of control sampling section is measured flue-gas temperature with RTD simultaneously about 130 ℃ in sampling process, is furnished with separable hanger at handle part at traditional smoke dust sampling filter cylinder outer wrap plate heater.Stainless steel filter cylinder frame is added at the position of dress filter cylinder in the traditional sampling head, prevents that filter cylinder is broken.When in gathering thing, containing dirt attitude and vapor-phase fluoride, the hanger apolegamy is in series with 3 large-scale impact type absorption bottles that 75ml solution is housed, and interior dress sodium hydroxide solution gathers respectively dirt attitude and vapor-phase fluoride through filter cylinder and absorption bottle; If when only containing vapor-phase fluoride in the collection thing, the porous glass plate absorption bottle that the apolegamy hanger only need be connected two 50ml solution is housed.Twine the heating tape in the whole flue gas sampling pipe, heating-up temperature 110-130 ℃.The connecting pipe that uses is a polyfluortetraethylene pipe all, and it is minimum that adhesion effect is reduced to.This sampling rifle is rational in infrastructure, and gaseous state in the flue and the sampling of dirt attitude fluoride are combined, and the overall process heating prevents to produce condensate water, avoids fluoride to be dissolved in condensate water; Cause measuring error, and built-in filter cylinder frame, when smoke moisture is bigger, cause when filter cylinder is broken to be difficult for taking out; The filter cylinder frame can be brought into play protection and the fixedly effect of filter cylinder, and its inner highly versatile that connects is easy to maintenance, simple appearance; Telotism, in light weight, use easy to carryly, measurement of soot and dust concentration is accurate.
