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 the separable hanger 20 of handle 11 arranged outside, 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.
